Description
本発明は、基材部の被覆に用いられる表皮部材、及び、その表皮部材により基材部が被覆されている内装部材に関する。 This invention relates to a surface material used for covering a base material, and to an interior component in which the base material is covered by the surface material.
特開２０１９－８９５３６号公報（特許文献１）には、基材部を被覆する表皮部材が記載されている。この特許文献１に記載されている表皮部材は、２つの表皮片のそれぞれの側縁部（表皮側縁部）をＵ字状に折り曲げて、更に、その側縁部の折り曲げられた部分同士を互いに突き合わせて縫い合わせることによって、形成されている。 Japanese Patent Publication No. 2019-89536 (Patent Document 1) describes a skin member for covering a base material. The skin member described in Patent Document 1 is formed by folding the side edges (side edges) of two skin pieces into a U-shape, and then sewing the folded portions of these side edges together.
また従来において、表皮部材を基材部に被せるときには、基材部の表面に接着剤を塗布して接着層を形成するとともに、例えば図７に示すように、表皮部材９０の裏面の一部にも接着剤を塗布して接着層９５を形成することがある。これにより、基材部と表皮部材９０とを、基材部の接着層及び表皮部材９０の接着層９５を介して貼り合わせることができる。またこの場合、表皮部材９０の左右の表皮片９１については、各表皮片９１における表皮側縁部９２の内周面全面にも接着剤を塗布して接着層９５を形成することにより、表皮側縁部９２のＵ字状に折り曲げられた形状を固定することがある。 Furthermore, conventionally, when covering a base material with a skin member, an adhesive layer is applied to the surface of the base material to form an adhesive layer, and, as shown in Figure 7, an adhesive layer 95 is also sometimes applied to a portion of the back surface of the skin member 90. This allows the base material and the skin member 90 to be bonded together via the adhesive layer of the base material and the adhesive layer 95 of the skin member 90. In this case, for the left and right skin pieces 91 of the skin member 90, an adhesive layer 95 may also be applied to the entire inner surface of the skin side edge 92 of each skin piece 91 to fix the U-shaped bend of the skin side edge 92.
図７に示したように、表皮部材９０は、左右の各表皮片９１の表皮側縁部９２がそれぞれＵ字状に折り曲げられた状態で基材部に被せられて取り付けられる（固定される）。このような従来の表皮部材９０において、例えば表皮部材９０を、左右の表皮片９１を突き合わせる部分を、左右にカーブさせるように湾曲した形状で形成する場合等では、Ｕ字状に折り曲げられた表皮側縁部９２の裏面側（所謂、縫い代の部分）がよれ易くなることや、その裏面側に皺が部分的に発生すること等があった。 As shown in Figure 7, the skin member 90 is attached (fixed) to the base material by covering it with the skin side edges 92 of each of the left and right skin pieces 91, which are folded into a U-shape. In such conventional skin members 90, for example, when the skin member 90 is formed with a curved shape so that the parts where the left and right skin pieces 91 abut are curved to the left and right, the back side (the so-called seam allowance) of the U-shaped folded skin side edges 92 tends to wrinkle easily, and wrinkles may partially occur on the back side.
しかし、この表皮部材９０では、図７に示したように、表皮側縁部９２のＵ字状に折り曲げられた形状が接着層９５によって固定されているため、表皮側縁部９２の裏面側に生じたよれた形状（歪んだ形状）や皺等も接着層９５によって固定され、そのよれた形状や皺等が、接着層９５を介して表皮部材９０の外面に凸部（凸形状）として表出することがあった。その結果、表皮部材９０が取り付けられた製品（例えば、内装部材等）の外観品質が損なわれることがあった。 However, in this surface member 90, as shown in Figure 7, the U-shaped bend of the surface edge 92 is fixed by the adhesive layer 95. Therefore, any distortions or wrinkles that occur on the back side of the surface edge 92 are also fixed by the adhesive layer 95, and these distortions or wrinkles may appear as protrusions (convex shapes) on the outer surface of the surface member 90 via the adhesive layer 95. As a result, the appearance quality of the product to which the surface member 90 is attached (e.g., interior components) may be impaired.
本発明は上記従来の課題に鑑みてなされたものであって、その目的は、表皮側縁部に生じるよれた形状や皺等に起因して製品の外観品質が低下することを防止又は抑制可能な表皮部材、及び、その表皮部材により基材部が被覆されている内装部材を提供することにある。 This invention has been made in view of the above-mentioned conventional problems, and its object is to provide a surface member capable of preventing or suppressing a deterioration in the appearance quality of a product caused by wrinkles or other distortions that occur on the side edges of the surface, and an interior member in which the base material is covered by the surface member.
上記目的を達成するために、本発明によれば、表皮本体部と、前記表皮本体部から第１方向の一方に延びて、更に前記第１方向の他方に折り返されることにより、略Ｕ字状に折り曲げられた形状を備える表皮側縁部とを有し、前記表皮側縁部は、前記表皮本体部に接続する基端部と、前記基端部から延びるとともに折り曲げられる折曲部と、前記折曲部から延びるとともに前記基端部の裏面側に重ねられる折り返し縁部とを有し、前記基端部の一部の内周面と、前記折曲部の内周面と、前記折り返し縁部の少なくとも一部の内周面とに接着層が設けられ、前記基端部の内周面は、前記接着層が設けられていない非接着面を有する表皮部材が提供される。 To achieve the above objective, the present invention provides a skin member comprising a skin body portion and a skin side edge portion extending from the skin body portion in one direction in a first direction and further folded back in the other direction in the first direction, thereby forming a substantially U-shape. The skin side edge portion comprises a base end portion connected to the skin body portion, a bent portion extending from the base end portion and being bent, and a folded edge portion extending from the bent portion and overlapping the back surface of the base end portion. An adhesive layer is provided on the inner circumferential surface of a portion of the base end portion, the inner circumferential surface of the bent portion, and at least a portion of the inner circumferential surface of the folded edge portion, while the inner circumferential surface of the base end portion is a non-adhesive surface without the adhesive layer.
本発明の表皮部材において、前記基端部の前記非接着面は、前記第１方向に沿った断面視において、前記基端部の前記表皮本体部に対する境界部から、前記折曲部に近付く方向に向けて連続的に配されていることが好ましい。
また、前記基端部の前記非接着面は、前記第１方向に沿った断面視において、前記基端部の内周面の半分の範囲、又は前記半分を超える範囲に配されていることが好ましい。
In the skin member of the present invention, it is preferable that the non-adhesive surface of the base end is arranged continuously in a cross-sectional view along the first direction, from the boundary portion of the base end with respect to the skin body portion toward the bent portion.
Furthermore, it is preferable that the non-adhesive surface of the base end is located in a cross-sectional view along the first direction, within half or more of the range of the inner circumferential surface of the base end.
また、本発明の表皮部材において、前記折り返し縁部の内周面は、前記接着層が設けられていない非接着面を有し、前記第１方向に沿った断面視において、前記基端部の前記非接着面の少なくとも一部と、前記折り返し縁部の前記非接着面の少なくとも一部とは、互いに対向して配されている。 Furthermore, in the surface member of the present invention, the inner circumferential surface of the folded edge portion has a non-adhesive surface where the adhesive layer is not provided, and in a cross-sectional view along the first direction, at least a portion of the non-adhesive surface of the base end portion and at least a portion of the non-adhesive surface of the folded edge portion are arranged facing each other.
更に本発明によれば、上述した構成を備える前記表皮部材と、前記表皮部材により被覆されている基材部とを有する内装部材が提供される。 Furthermore, according to the present invention, an interior member is provided having the above-described surface member and a base material portion covered by the surface member.
本発明によれば、表皮側縁部に生じるよれた形状や皺等を接着層に固定され難くして、よれた形状や皺等に起因して製品の外観品質が低下することを防止又は抑制できる表皮部材と、その表皮部材により基材部が被覆されている内装部材とが提供される。 According to the present invention, a surface member is provided that makes it difficult for wrinkles and other distortions that occur on the side edges of the surface to be fixed to the adhesive layer, thereby preventing or suppressing a deterioration in the appearance quality of the product caused by such distortions and distortions; and an interior member is provided in which the base material is covered by the surface member.

本実施例１の内装部材１は、自動車の車室に用いられる内装部材１であり、例えば自動車のインストルメントパネル、ガーニッシュ、又はコンソールボックス等に用いられる。また、本実施例１の内装部材１は、車内の設置部位に応じた所定の形状を有する基材部１０と、基材部１０を外側から被覆する表皮部材２０とを有する。 The interior component 1 of this embodiment 1 is an interior component 1 used in the passenger compartment of an automobile, for example, in the instrument panel, garnish, or console box of an automobile. Furthermore, the interior component 1 of this embodiment 1 has a base material portion 10 having a predetermined shape according to the installation location in the vehicle, and a surface material 20 that covers the base material portion 10 from the outside.
なお、以下の内装部材１に関する説明において、上下方向は、基材部１０に対して表皮部材２０を近接・離間させる方向に沿った方向を意味し、例えば図１の紙面における上下方向と同じ方向である。この場合、表皮部材２０を基材部１０に近付ける向きを下方とし、表皮部材２０を基材部１０から離間させる向きを上方とする。左右方向は、表皮部材２０を後述する縫い合わせ部３２に交差する方向（好ましくは、縫い合わせ部３２に直交する方向）に切断したときの断面視において、上下方向に直交する方向を意味し、例えば図１の紙面における左右方向と同じ方向である。また、本実施例１及び後述する実施例２における左右方向は、特許請求の範囲に規定する第１方向に対応する方向である。前後方向は、上下方向と左右方向とに直交する方向を意味し、例えば図１の紙面の表裏方向と同じ方向である。 In the following description of the interior component 1, the vertical direction refers to the direction along which the surface component 20 is brought closer to or further away from the base material 10, and is the same direction as the vertical direction on the plane of Figure 1. In this case, the direction that brings the surface component 20 closer to the base material 10 is defined as downward, and the direction that moves the surface component 20 further away from the base material 10 is defined as upward. The left-right direction refers to the direction perpendicular to the vertical direction in a cross-sectional view when the surface component 20 is cut in a direction intersecting the stitching portion 32 (preferably perpendicular to the stitching portion 32), and is the same direction as the left-right direction on the plane of Figure 1. Furthermore, the left-right direction in this embodiment 1 and embodiment 2 described later corresponds to the first direction defined in the claims. The front-back direction refers to the direction perpendicular to the vertical direction and the left-right direction, and is the same direction as the front-back direction on the plane of Figure 1.
内装部材１の基材部１０は、合成樹脂により形成されており、取り付けられた表皮部材２０を支持している。基材部１０は、表皮部材２０に覆われる外面１１と、外面１１に対して凹設される凹溝部１２とを有する。基材部１０の凹溝部１２は、表皮部材２０における後述する左右の表皮側縁部２３の一部（具体的には、表皮側縁部２３における折り返し縁部２６と折曲部２５の下半部）を収容して保持する部分であり、表皮部材２０で左右の表皮側縁部２３が配される位置に対応して設けられている。また、基材部１０の外面１１には、基材側接着層１３が設けられている。本実施例１において、基材側接着層１３は、表皮部材２０に形成される後述の第２接着層４２の形成部分に対応して設けられている。 The base material portion 10 of the interior component 1 is made of synthetic resin and supports the attached surface component 20. The base material portion 10 has an outer surface 11 covered by the surface component 20 and a recessed groove portion 12 formed in relation to the outer surface 11. The recessed groove portion 12 of the base material portion 10 is a portion that accommodates and holds a part of the left and right surface edge portions 23 of the surface component 20 (specifically, the folded edge portion 26 and the lower half of the bent portion 25 of the surface edge portion 23), and is provided corresponding to the positions where the left and right surface edge portions 23 are arranged on the surface component 20. Furthermore, a base material side adhesive layer 13 is provided on the outer surface 11 of the base material portion 10. In this embodiment 1, the base material side adhesive layer 13 is provided corresponding to the portion where the second adhesive layer 42, described later, is formed on the surface component 20.
なお本発明において、基材部１０の材質、大きさ、及び形状、凹溝部１２の大きさ及び形状、並びに、基材側接着層１３の材質等は特に限定されない。また、基材部１０は、例えば上述した凹溝部１２を設けずに形成されていてもよく、また、基材側接着層１３を設けずに形成されていてもよい。 In this invention, the material, size, and shape of the base material portion 10, the size and shape of the groove portion 12, and the material of the base material side adhesive layer 13 are not particularly limited. Furthermore, the base material portion 10 may be formed without the groove portion 12 described above, or without the base material side adhesive layer 13.
本実施例１の内装部材１において、表皮部材２０は、基材部１０を外側から被覆するとともに、表皮部材２０の一部が基材部１０の凹溝部１２に収容されるようにして基材部１０に取り付けられている。表皮部材２０は、表皮本体部２２及び表皮側縁部２３を備える２つの表皮片２１と、２つの表皮片２１を縫い合わせる縫合部３１と、表皮片２１における表皮側縁部２３の内周面に設けられる第１接着層４１と、表皮片２１の表皮本体部２２を基材部１０に固定する第２接着層４２とを有する。 In the interior member 1 of this embodiment 1, the skin member 20 covers the base material 10 from the outside and is attached to the base material 10 such that a part of the skin member 20 is housed in the groove 12 of the base material 10. The skin member 20 comprises two skin pieces 21, each having a skin body portion 22 and a skin side edge portion 23; a suture portion 31 that stitches the two skin pieces 21 together; a first adhesive layer 41 provided on the inner circumferential surface of the skin side edge portion 23 of the skin piece 21; and a second adhesive layer 42 that fixes the skin body portion 22 of the skin piece 21 to the base material 10.
本実施例１において、表皮部材２０を形成する２つの表皮片２１のうち、縫合部３１に対して左右方向の一方側（例えば左側）に配される表皮片２１を第１表皮片２１ａと規定し、左右方向の他方側（例えば右側）に配される表皮片２１を第２表皮片２１ｂと規定する。 In this embodiment 1, of the two epidermal pieces 21 forming the epidermal member 20, the epidermal piece 21 located on one side in the left-right direction relative to the suture portion 31 (for example, the left side) is defined as the first epidermal piece 21a, and the epidermal piece 21 located on the other side in the left-right direction (for example, the right side) is defined as the second epidermal piece 21b.
第１表皮片２１ａ及び第２表皮片２１ｂは、布等の生地又は合成皮革等の皮革により、薄く形成されている。また、第１表皮片２１ａ及び第２表皮片２１ｂは、基材部１０を被覆可能な大きさ及び形状を有するとともに、可撓性を備えている。第１表皮片２１ａと第２表皮片２１ｂとは、縫合部３１によって縫い合わされている。また、第１表皮片２１ａと第２表皮片２１ｂの縫い合わせ部（突き合わせ部）３２は、基材部１０に取り付けられた表皮部材２０を上方から見たときに（図２を参照）、１本の線のように連続して形成されている。 The first and second skin pieces 21a and 21b are thinly formed from fabric such as cloth or leather such as synthetic leather. Furthermore, the first and second skin pieces 21a and 21b have a size and shape that allows them to cover the base material 10, and are also flexible. The first and second skin pieces 21a and 21b are sewn together by a suture portion 31. The suture portion (butt joint) 32 of the first and second skin pieces 21a and 21b is formed as a continuous line when the skin member 20 attached to the base material 10 is viewed from above (see Figure 2).
本実施例１の第１表皮片２１ａ及び第２表皮片２１ｂは、それぞれ、基材部１０の外面１１に沿って配されることにより基材部１０を被覆する表皮本体部２２と、表皮部材２０の縫い合わせ部３２に交差する断面（図１）を見たときに略Ｕ字状に折り曲げられた形状を備える表皮側縁部２３とを有する。なお、本実施例１において、表皮部材２０の縫い合わせ部３２に交差する断面（好ましくは、縫い合わせ部３２に直交する断面）は、左右方向（第１方向）に沿った断面と言うこともできる。また、以下の説明において、「表皮部材２０の断面視」という記載は、表皮部材２０の縫い合わせ部３２に交差する断面を見るときのことを意味する。 In this embodiment 1, the first skin piece 21a and the second skin piece 21b each have a skin body portion 22 that covers the base material portion 10 by being arranged along the outer surface 11 of the base material portion 10, and a skin side edge portion 23 that has a shape that is bent into a substantially U shape when viewed in cross-section (Figure 1) intersecting the seam portion 32 of the skin member 20. In this embodiment 1, the cross-section intersecting the seam portion 32 of the skin member 20 (preferably a cross-section perpendicular to the seam portion 32) can also be said to be a cross-section along the left-right direction (first direction). Furthermore, in the following description, the phrase "cross-sectional view of the skin member 20" refers to the view of the cross-section intersecting the seam portion 32 of the skin member 20.
本実施例１の表皮側縁部２３は、表皮本体部２２と一体的に形成されているとともに、表皮本体部２２から連続的に延びている。また、表皮側縁部２３は、表皮部材２０の断面視（図１）において、表皮本体部２２から左右方向の一方に延びて、更に、左右方向の他方に折り返されることによって略Ｕ字状に形成されている。 In this embodiment 1, the skin side edge 23 is integrally formed with the skin main body 22 and extends continuously from the skin main body 22. Furthermore, in a cross-sectional view of the skin member 20 (Figure 1), the skin side edge 23 extends from the skin main body 22 in one direction (left-right) and is then folded back to the other direction (left-right), forming a roughly U-shape.
このような略Ｕ字状の表皮側縁部２３は、表皮本体部２２に接続する基端部２４と、基端部２４から表皮本体部２２とは反対の方向に延びるとともに折り曲げられる折曲部２５と、折曲部２５から更に延びるとともに基端部２４の裏面側に重ねられる折り返し縁部２６とを有する。 This roughly U-shaped skin edge portion 23 has a base end portion 24 connected to the skin body portion 22, a bent portion 25 extending from the base end portion 24 in the direction opposite to the skin body portion 22 and being bent, and a folded edge portion 26 further extending from the bent portion 25 and overlapping the back side of the base end portion 24.
この場合、表皮部材２０の断面視（図１）において、例えば表皮側縁部２３における折り返し縁部２６の先端の位置から、上下方向に沿う直線を仮想的に延ばしたときに、その仮想的な直線と表皮片２１とが交わる位置を、その表皮片２１における表皮本体部２２と表皮側縁部２３の境界部２７とする。ここで、折り返し縁部２６の先端は、表皮部材２０の断面視（図１）において、折り返し縁部２６における折曲部２５に接続する側とは反対側の末端を意味する。 In this case, in a cross-sectional view of the skin member 20 (Figure 1), if a straight line is virtually extended vertically from, for example, the tip of the folded edge portion 26 on the skin side edge portion 23, the position where this virtual line intersects with the skin piece 21 is defined as the boundary portion 27 between the skin main body portion 22 and the skin side edge portion 23 on the skin piece 21. Here, the tip of the folded edge portion 26 refers to the end of the folded edge portion 26 opposite to the side connected to the bent portion 25 in the cross-sectional view of the skin member 20 (Figure 1).
また本実施例１において、表皮部材２０の裏面及び表皮片２１の裏面とは、表皮部材２０及び表皮片２１の互いに反対側に配される第１表面及び第２表面のうち、基材部１０に面する側又は対向する側の表面を意味する。また、略Ｕ字状の表皮側縁部２３は、前記断面視において、内側に配される内周面と、外側に向く外周面とを有する。この場合、表皮側縁部２３における基端部２４の外周面が、表皮片２１の外部に露呈する表面（外面）の一部を形成し、また、表皮側縁部２３における折り返し縁部２６の外周面が、表皮片２１の基材部１０に対向する裏面（内面）となる。 In this embodiment 1, the back surface of the skin member 20 and the back surface of the skin piece 21 refer to the first and second surfaces of the skin member 20 and skin piece 21, which are located on opposite sides of each other, and which face or are opposite to the base material 10. Furthermore, the substantially U-shaped skin side edge 23 has an inner circumferential surface located on the inside and an outer circumferential surface facing outwards in the cross-sectional view. In this case, the outer circumferential surface of the base end 24 of the skin side edge 23 forms a part of the surface (outer surface) exposed to the outside of the skin piece 21, and the outer circumferential surface of the folded edge 26 of the skin side edge 23 becomes the back surface (inner surface) of the skin piece 21 facing the base material 10.
本実施例１の第１表皮片２１ａ及び第２表皮片２１ｂにおいて、表皮側縁部２３の基端部２４は、上述した境界部２７から、左右方向の内側に向けて、表皮本体部２２に沿うように延びている。ここで、左右方向の内側とは、左右方向において縫い合わせる相手側の表皮片２１に近付く向きを意味する。 In the first epidermal piece 21a and the second epidermal piece 21b of this embodiment 1, the base end portion 24 of the epidermal side edge portion 23 extends inward in the left-right direction from the boundary portion 27 described above, along the epidermal main body portion 22. Here, "inward in the left-right direction" means the direction approaching the epidermal piece 21 that will be sutured together in the left-right direction.
表皮側縁部２３の折曲部２５は、基端部２４における境界部２７とは反対側の端縁から下方に向けて、左右方向の内側へ凸状に膨らむように湾曲しながら延びている。表皮側縁部２３の折り返し縁部２６は、折曲部２５における基端部２４に接続する側とは反対側の端縁から、左右方向の外側に向けて、基端部２４と平行又は略平行に延びている。 The bent portion 25 of the skin side edge 23 extends downward from the edge opposite to the boundary portion 27 at the base end 24, curving inward in a convex shape in the left-right direction. The folded edge 26 of the skin side edge 23 extends outward in the left-right direction from the edge opposite to the side connecting to the base end 24 at the bent portion 25, parallel or approximately parallel to the base end 24.
縫合部３１は、第１表皮片２１ａと第２表皮片２１ｂを縫い合わせる縫製加工を行うことによって形成されており、また、第１表皮片２１ａ及び第２表皮片２１ｂを刺通して縫い合わせる縫製糸により形成されている。本実施例１では、表皮部材２０を上側から見た平面視（図２）において、縫合部３１によって縫い合わされた第１表皮片２１ａと第２表皮片２１ｂの縫い合わせ部３２（言い換えると、第１表皮片２１ａと第２表皮片２１ｂの突き合わせ部３２）は、左右方向にカーブするように湾曲した形状に形成されている。その結果、表皮部材２０の裏面側では、例えば図３に示したように、第１表皮片２１ａ及び第２表皮片２１ｂの折り返し縁部２６に、よれた形状（歪んだ形状）３５や皺が形成され易くなる。 The suture portion 31 is formed by sewing together the first epidermal piece 21a and the second epidermal piece 21b, and is also formed by sewing thread that pierces and sews together the first epidermal piece 21a and the second epidermal piece 21b. In this embodiment 1, in a plan view of the epidermal member 20 from above (Figure 2), the suture portion 32 of the first epidermal piece 21a and the second epidermal piece 21b sewn together by the suture portion 31 (in other words, the butt joint portion 32 of the first epidermal piece 21a and the second epidermal piece 21b) is formed in a curved shape that curves in the left-right direction. As a result, on the back side of the epidermal member 20, for example, as shown in Figure 3, wrinkles and distorted shapes 35 are easily formed on the folded edges 26 of the first epidermal piece 21a and the second epidermal piece 21b.
表皮部材２０の第１接着層４１及び第２接着層４２は、表皮片２１に接着剤を塗布することによって形成されている。本実施例１の第１接着層４１は、表皮側縁部２３における基端部２４の内周面の一部と、折曲部２５の内周面の全体と、折り返し縁部２６の内周面の全体とに設けられている。このように第１接着層４１が設けられていることにより、表皮側縁部２３の略Ｕ字状に折り曲げられた形状を固定できる。 The first adhesive layer 41 and the second adhesive layer 42 of the skin member 20 are formed by applying adhesive to the skin piece 21. In this embodiment 1, the first adhesive layer 41 is provided on a portion of the inner circumferential surface of the base end portion 24 of the skin side edge 23, the entire inner circumferential surface of the bent portion 25, and the entire inner circumferential surface of the folded edge portion 26. By providing the first adhesive layer 41 in this way, the substantially U-shaped bend of the skin side edge 23 can be fixed.
また、表皮側縁部２３における基端部２４の内周面は、第１接着層４１が設けられていない非接着面４５を有する。本実施例１において、基端部２４に設けられる非接着面４５は、表皮部材２０の断面視（図１）において、基端部２４及び表皮本体部２２間の境界部２７から、折曲部２５に近付く方向に向けて連続的に延びている。この場合、基端部２４の非接着面４５は、基端部２４の内周面の全体の５０％の範囲に、又は、内周面の全体の５０％を少し超える範囲に配されている。 Furthermore, the inner circumferential surface of the base end portion 24 at the skin side edge portion 23 has a non-adhesive surface 45 where the first adhesive layer 41 is not provided. In this embodiment 1, the non-adhesive surface 45 provided on the base end portion 24 extends continuously from the boundary portion 27 between the base end portion 24 and the skin main body portion 22 towards the bent portion 25 in a cross-sectional view of the skin member 20 (Figure 1). In this case, the non-adhesive surface 45 of the base end portion 24 is located in an area of 50% of the entire inner circumferential surface of the base end portion 24, or in an area slightly exceeding 50% of the entire inner circumferential surface.
このような非接着面４５が表皮側縁部２３の基端部２４に設けられていることにより、第１表皮片２１ａ及び第２表皮片２１ｂの折り返し縁部２６に図３に示したようなよれた形状３５や皺等が生じたとしても、そのよれた形状３５や皺等に起因するような凸部（凸形状）を表皮部材２０の外面に、特に、表皮側縁部２３の基端部２４の外面に、表出させ難くすることができる。 Because such a non-adhesive surface 45 is provided at the base end 24 of the epidermal side edge 23, even if a distorted shape 35 or wrinkles occur on the folded edge 26 of the first epidermal piece 21a and the second epidermal piece 21b as shown in Figure 3, it is difficult to make any protrusions (convex shapes) caused by such distorted shapes 35 or wrinkles appear on the outer surface of the epidermal member 20, particularly on the outer surface of the base end 24 of the epidermal side edge 23.
本実施例１の第２接着層４２は、表皮部材２０を基材部１０に固定するために、表皮本体部２２の裏面（内面）に設けられている。なお本実施例１において、第２接着層４２は、表皮本体部２２の裏面の少なくとも一部に設けられていればよく、第２接着層４２の形成範囲は限定されない。 In this embodiment 1, the second adhesive layer 42 is provided on the back surface (inner surface) of the skin body portion 22 in order to fix the skin member 20 to the base material portion 10. In this embodiment 1, the second adhesive layer 42 only needs to be provided on at least a portion of the back surface of the skin body portion 22; the formation area of the second adhesive layer 42 is not limited.
本実施例１において、表皮本体部２２の裏面は、第２接着層４２が設けられていない非接着面４５を有する。この場合、表皮本体部２２の非接着面４５は、表皮本体部２２及び基端部２４間の境界部２７から、折曲部２５から離れる方向に向けて連続的に延びており、また、基端部２４の上述した非接着面４５に連続して形成されている。 In this embodiment 1, the back surface of the epidermal body portion 22 has a non-adhesive surface 45 where the second adhesive layer 42 is not provided. In this case, the non-adhesive surface 45 of the epidermal body portion 22 extends continuously from the boundary portion 27 between the epidermal body portion 22 and the base end portion 24 in a direction away from the bent portion 25, and is also formed continuously with the aforementioned non-adhesive surface 45 of the base end portion 24.
表皮部材２０の非接着面４５が、上述のように境界部２７を介して表皮側縁部２３の基端部２４と表皮本体部２２とに亘って連続的に形成されていることにより、表皮部材２０の表皮側縁部２３が、基材部１０の凹溝部１２内にて、凹溝部１２の長さ方向に沿って僅かに移動することを許容できる。これにより、表皮部材２０の表皮側縁部２３を、凹溝部１２の形状に沿って、凹溝部１２内に容易に挿入して収容できる。また、表皮部材２０の表皮側縁部２３を、凹溝部１２内で基材部１０に引っ掛かり難くすることができるため、表皮部材２０の引っ掛かりに起因して表皮部材２０に皺等が発生することを抑制できる。 As described above, the non-adhesive surface 45 of the skin member 20 is continuously formed across the base end 24 of the skin side edge 23 and the skin main body 22 via the boundary portion 27. This allows the skin side edge 23 of the skin member 20 to move slightly along the length of the groove 12 within the groove 12 of the base material 10. This allows the skin side edge 23 of the skin member 20 to be easily inserted and accommodated within the groove 12, following its shape. Furthermore, since the skin side edge 23 of the skin member 20 is less likely to catch on the base material 10 within the groove 12, wrinkles and other damage to the skin member 20 caused by catching can be suppressed.
次に、本実施例１の表皮部材２０を作製する方法について説明する。
先ず、所要の形状に裁断された第１表皮片２１ａ及び第２表皮片２１ｂを用意する。続いて、用意された第１表皮片２１ａ及び第２表皮片２１ｂに対して縫製加工を行う。この縫製加工によって、縫製糸を第１表皮片２１ａ及び第２表皮片２１ｂに刺通させて、縫製糸による縫合部３１を形成するとともに、その縫合部３１で第１表皮片２１ａと第２表皮片２１ｂとを縫い合わせる。
Next, a method for manufacturing the skin member 20 of this embodiment 1 will be described.
First, a first skin piece 21a and a second skin piece 21b are prepared, cut to the required shape. Next, the prepared first skin piece 21a and second skin piece 21b are subjected to sewing. This sewing process involves inserting sewing thread through the first skin piece 21a and the second skin piece 21b to form a sutured portion 31, and sewing the first skin piece 21a and the second skin piece 21b together with this sutured portion 31.
次に、縫合部３１によって縫い合わされた第１表皮片２１ａと第２表皮片２１ｂとに対し、図４に示すようにマスキング５０を形成して、このマスキング５０によって第１表皮片２１ａ及び第２表皮片２１ｂの一部を被覆する。この場合、マスキング５０は、表皮本体部２２の裏面及び表皮側縁部２３の内周面を形成する表皮片２１の一方の面に形成される。なお本発明において、マスキング５０を形成する方法は特に限定されない。 Next, as shown in Figure 4, a masking tape 50 is formed on the first epidermal piece 21a and the second epidermal piece 21b, which are sutured together by the suture portion 31, thereby covering a portion of the first epidermal piece 21a and the second epidermal piece 21b. In this case, the masking tape 50 is formed on one side of the epidermal piece 21 that forms the back surface of the epidermal body portion 22 and the inner circumferential surface of the epidermal side edge portion 23. Note that the method for forming the masking tape 50 is not particularly limited in this invention.
第１表皮片２１ａ及び第２表皮片２１ｂにマスキング５０を形成した後、第１表皮片２１ａ及び第２表皮片２１ｂの前記一方の面に接着剤を塗布することによって接着層４０を形成する（図４を参照）。また、接着層４０が形成された後、第１表皮片２１ａ及び第２表皮片２１ｂからマスキング５０を剥がすことにより、マスキング５０上に形成された接着層４０が除去されるため、第１表皮片２１ａ及び第２表皮片２１ｂの一方の面に非接着面４５が形成される。この場合、第１表皮片２１ａ及び第２表皮片２１ｂに形成された接着層４０のうち、非接着面４５の位置よりも表皮側縁部２３側に形成されている接着層４０が第１接着層４１となり、非接着面４５の位置よりも表皮側縁部２３の反対側に形成されている接着層４０が第２接着層４２となる。 After forming masking 50 on the first epidermal piece 21a and the second epidermal piece 21b, an adhesive layer 40 is formed by applying adhesive to one of the surfaces of the first and second epidermal pieces 21a and 21b (see Figure 4). Furthermore, after the adhesive layer 40 is formed, the masking 50 is peeled off from the first and second epidermal pieces 21a and 21b, removing the adhesive layer 40 formed on the masking 50, thus forming a non-adhesive surface 45 on one of the surfaces of the first and second epidermal pieces 21a and 21b. In this case, of the adhesive layers 40 formed on the first and second epidermal pieces 21a and 21b, the adhesive layer 40 formed on the side of the epidermal edge 23 closer to the non-adhesive surface 45 becomes the first adhesive layer 41, and the adhesive layer 40 formed on the opposite side of the epidermal edge 23 from the non-adhesive surface 45 becomes the second adhesive layer 42.
その後、接着層４０及び非接着面４５が形成された第１表皮片２１ａ及び第２表皮片２１ｂを、図５に示すように、それぞれ、縫合部３１の位置で折り曲げて折曲部２５を形成するとともに、その折曲部２５から延びる折り返し縁部２６を基端部２４に重ね合わせる。このとき、第１表皮片２１ａ及び第２表皮片２１ｂは、縫合部３１及びその周辺部に形成されている接着層４０が内側に包まれるように折り曲げられて、当該接着層４０同士が貼り合わせられる。 Subsequently, the first epidermal piece 21a and the second epidermal piece 21b, each with the adhesive layer 40 and non-adhesive surface 45 formed on them, are folded at the suture portion 31 to form a folded portion 25, as shown in Figure 5. The folded edge portion 26 extending from the folded portion 25 is then overlapped with the base end portion 24. At this time, the first epidermal piece 21a and the second epidermal piece 21b are folded so that the adhesive layer 40 formed on the suture portion 31 and its surrounding area is enclosed inward, and the adhesive layers 40 are bonded together.
以上の工程を行うことにより、図１～図３に示すような表皮部材２０が作製される。
なお本発明において、表皮部材２０の作製方法は特に限定されない。例えば本実施例１では、第１表皮片２１ａと第２表皮片２１ｂとを縫合部３１で縫い合わせた後に、第１表皮片２１ａ及び第２表皮片２１ｂに接着層４０（第１接着層４１及び第２接着層４２）を形成することによって、表皮部材２０を作製している。しかし本発明では、第１表皮片２１ａ及び第２表皮片２１ｂに接着層４０を形成した後に、その接着層４０を備えた第１表皮片２１ａと第２表皮片２１ｂとを縫合部３１で縫い合わせることによって表皮部材２０が作製されてもよい。
By performing the above steps, a skin member 20 as shown in Figures 1 to 3 is produced.
In the present invention, the method for manufacturing the epidermal member 20 is not particularly limited. For example, in this embodiment 1, the epidermal member 20 is manufactured by sewing together the first epidermal piece 21a and the second epidermal piece 21b at the suture portion 31, and then forming adhesive layers 40 (first adhesive layer 41 and second adhesive layer 42) on the first epidermal piece 21a and the second epidermal piece 21b. However, in the present invention, the epidermal member 20 may also be manufactured by forming adhesive layers 40 on the first epidermal piece 21a and the second epidermal piece 21b, and then sewing together the first epidermal piece 21a and the second epidermal piece 21b, which are equipped with the adhesive layers 40, at the suture portion 31.
以上の工程が行われて作製された表皮部材２０は、その後、別途に形成された凹溝部１２を有する基材部１０に取り付けられる。このとき、表皮部材２０は、図１に示すように、表皮本体部２２で基材部１０の外面１１を被覆するととともに、表皮側縁部２３を基材部１０の凹溝部１２内に挿入するようにして、基材部１０に取り付けられる。また、第１表皮片２１ａ及び第２表皮片２１ｂの表皮本体部２２に設けた第２接着層４２を、基材部１０に設けた基材側接着層１３に貼り合わせることにより、表皮本体部２２を基材部１０に固定する。これによって、基材部１０が表皮部材２０により被覆された本実施例１の内装部材１が製造される。 The surface member 20 manufactured through the above process is then attached to a base material 10 having a separately formed groove 12. At this time, as shown in Figure 1, the surface member 20 is attached to the base material 10 by covering the outer surface 11 of the base material 10 with the surface body portion 22 and inserting the surface side edge portion 23 into the groove 12 of the base material 10. Furthermore, the surface body portion 22 is fixed to the base material 10 by bonding the second adhesive layer 42 provided on the surface body portion 22 of the first surface piece 21a and the second surface piece 21b to the base material side adhesive layer 13 provided on the base material 10. This manufactures the interior member 1 of this embodiment 1, in which the base material 10 is covered with the surface member 20.
上述のように製造された本実施例１の内装部材１では、第１表皮片２１ａ及び第２表皮片２１ｂの各表皮側縁部２３に第１接着層４１と非接着面４５とが設けられている。特に、非接着面４５は、表皮部材２０の断面視において、基端部２４の内周面の半分の範囲に、又は、基端部２４の内周面の半分を少し超える範囲に設けられている（すなわち、非接着面４５は、基端部２４の内周面の半分以上の範囲に設けられている）。 In the interior member 1 of this embodiment 1, manufactured as described above, a first adhesive layer 41 and a non-adhesive surface 45 are provided on the surface edge portions 23 of the first surface piece 21a and the second surface piece 21b. In particular, the non-adhesive surface 45 is provided in a cross-sectional view of the surface member 20, either in a range of half the inner circumferential surface of the base end portion 24, or in a range slightly exceeding half the inner circumferential surface of the base end portion 24 (i.e., the non-adhesive surface 45 is provided in a range of more than half the inner circumferential surface of the base end portion 24).
これにより、表皮側縁部２３の略Ｕ字状に折り曲げられた形状を、第１接着層４１によって安定して保持できる。また、第１表皮片２１ａ及び第２表皮片２１ｂの折り返し縁部２６に、図３に示したようなよれた形状３５や皺が発生しても、その折り返し縁部２６のよれた形状３５や皺（特に、よれた形状３５及び皺の左右方向の外側端部）が、第１接着層４１を介して表皮側縁部２３の基端部２４に固定され難くなり、且つ、よれた形状３５や皺が表皮側縁部２３の折り返し縁部２６にて分散し易くなる。 This allows the roughly U-shaped folded form of the epidermal side edge 23 to be stably maintained by the first adhesive layer 41. Furthermore, even if wrinkles or distortions occur on the folded edges 26 of the first epidermal piece 21a and the second epidermal piece 21b, as shown in Figure 3, these wrinkles and distortions (especially the outer ends of the wrinkles and distortions in the left-right direction) become less likely to be fixed to the base end 24 of the epidermal side edge 23 via the first adhesive layer 41. Moreover, the wrinkles and distortions become more easily dispersed on the folded edge 26 of the epidermal side edge 23.
このため、表皮部材２０の意匠面となる表面（外面）に、よれた形状３５や皺に起因する凸部（凸形状）を表出させ難くすることができる。その結果、内装部材１の外観品質が低下することを防止又は抑制できるため、良好な見栄え又は優れた外観性を備える内装部材１を安定して提供することができる。 Therefore, it is possible to prevent the appearance of distorted shapes 35 or protrusions (convex shapes) caused by wrinkles on the surface (outer surface) of the outer skin member 20, which is the design surface. As a result, it is possible to prevent or suppress a decrease in the appearance quality of the interior member 1, and thus be able to stably provide an interior member 1 with a good appearance or excellent aesthetic quality.
図６は、本実施例２の表皮部材の要部を模式的に示す断面図である。
図６に示した本実施例２の表皮部材６０は、例えば前述の実施例１の基材部１０に対し、基材部１０の外面１１を被覆するととともに、基材部１０の凹溝部１２内に表皮部材６０の一部を挿入するようにして被せられることによって、取り付けられている。このように本実施例２の表皮部材６０が基材部１０に取り付けられることによって、実施例１と同様の内装部材を形成できる。
Figure 6 is a schematic cross-sectional view showing the main part of the skin member of this embodiment 2.
The surface member 60 of this embodiment 2, shown in Figure 6, is attached, for example, to the base material 10 of the aforementioned embodiment 1 by covering the outer surface 11 of the base material 10 and inserting a part of the surface member 60 into the groove 12 of the base material 10. By attaching the surface member 60 of this embodiment 2 to the base material 10 in this way, an interior member similar to that of embodiment 1 can be formed.
本実施例２の表皮部材６０は、表皮本体部６２及び表皮側縁部６３を備える２つの表皮片６１（第１表皮片６１ａ及び第２表皮片６１ｂ）と、第１表皮片６１ａ及び第２表皮片６１ｂを縫い合わせる縫合部７１と、表皮片６１における表皮側縁部６３の内周面に設けられる接着層８０（第１接着層８１）と、表皮側縁部６３に形成される加飾縫製部８７とを有する。 The skin member 60 of this embodiment 2 comprises two skin pieces 61 (first skin piece 61a and second skin piece 61b) each having a skin body portion 62 and a skin side edge portion 63, a suture portion 71 for sewing the first skin piece 61a and the second skin piece 61b together, an adhesive layer 80 (first adhesive layer 81) provided on the inner circumferential surface of the skin side edge portion 63 of the skin piece 61, and a decorative stitched portion 87 formed on the skin side edge portion 63.
本実施例２の表皮部材６０は、前述の実施例１において表皮本体部２２に設けられる第２接着層４２を備えることなく形成されており、表皮本体部６２の裏面の全体が非接着面８５として形成されている。なお、本実施例２の表皮部材６０では、前述の実施例１と同様の第２接着層が、表皮部材６０の表皮本体部６２の裏面に形成されていてもよい。 In this embodiment 2, the skin member 60 is formed without the second adhesive layer 42 provided on the skin body portion 22 in the previously described embodiment 1, and the entire back surface of the skin body portion 62 is formed as a non-adhesive surface 85. However, in the skin member 60 of this embodiment 2, a second adhesive layer similar to that in the previously described embodiment 1 may be formed on the back surface of the skin body portion 62 of the skin member 60.
本実施例２の第１表皮片６１ａ、第２表皮片６１ｂ、及び縫合部７１は、前述の実施例１の第１表皮片２１ａ、第２表皮片２１ｂ、及び縫合部３１とそれぞれ実質的に同様に形成されている。すなわち、本実施例２の第１表皮片６１ａ及び第２表皮片６１ｂは、それぞれ、表皮本体部６２と、略Ｕ字状の表皮側縁部６３とを有する。また、略Ｕ字状の表皮側縁部６３は、基端部６４、折曲部６５、及び折り返し縁部６６を有する。 The first epidermal piece 61a, the second epidermal piece 61b, and the suture portion 71 of this embodiment 2 are formed substantially similarly to the first epidermal piece 21a, the second epidermal piece 21b, and the suture portion 31 of the aforementioned embodiment 1. That is, the first epidermal piece 61a and the second epidermal piece 61b of this embodiment 2 each have an epidermal body portion 62 and a substantially U-shaped epidermal side edge portion 63. Furthermore, the substantially U-shaped epidermal side edge portion 63 has a base portion 64, a bent portion 65, and a folded edge portion 66.
本実施例２の第１接着層８１は、表皮側縁部６３における基端部６４の内周面の一部と、折曲部６５の内周面の全体と、折り返し縁部６６の内周面の一部とに設けられており、この第１接着層８１により、表皮側縁部６３の略Ｕ字状に折り曲げられた形状が固定されている。 In this embodiment 2, the first adhesive layer 81 is provided on a portion of the inner circumferential surface of the base end portion 64 of the epidermal side edge portion 63, the entire inner circumferential surface of the bent portion 65, and a portion of the inner circumferential surface of the folded edge portion 66. This first adhesive layer 81 fixes the substantially U-shaped bend of the epidermal side edge portion 63.
表皮側縁部６３における基端部６４の内周面と折り返し縁部６６の内周面とは、第１接着層８１が設けられていない非接着面８５をそれぞれ有する。基端部６４の非接着面８５は、表皮部材６０の断面視（図６）において、基端部６４及び表皮本体部６２間の境界部６７から、折曲部６５に近付く方向に向けて連続的に延びており、また、基端部６４の内周面の全体の５０％の範囲に、又は、内周面の全体の５０％を少し超える範囲に配されている。折り返し縁部６６の非接着面８５は、折り返し縁部６６の先端から折曲部６５に近付く方向に向けて連続的に延びており、また、折り返し縁部６６の内周面の全体の５０％の範囲に、又は、内周面の全体の５０％を少し超える範囲に配されている。 The inner circumferential surfaces of the base end portion 64 and the folded edge portion 66 of the skin side edge 63 each have non-adhesive surfaces 85 where the first adhesive layer 81 is not provided. The non-adhesive surface 85 of the base end portion 64 extends continuously from the boundary portion 67 between the base end portion 64 and the skin main body portion 62 towards the folded portion 65 in a cross-sectional view of the skin member 60 (Figure 6), and is located within 50% of the entire inner circumferential surface of the base end portion 64, or slightly more than 50% of the entire inner circumferential surface. The non-adhesive surface 85 of the folded edge portion 66 extends continuously from the tip of the folded edge portion 66 towards the folded portion 65, and is located within 50% of the entire inner circumferential surface of the folded edge portion 66, or slightly more than 50% of the entire inner circumferential surface.
本実施例２において、基端部６４の非接着面８５と折り返し縁部６６の非接着面８５とは、互いに同じ面積又は略同じ面積で形成されている。また、基端部６４の非接着面８５と折り返し縁部６６の非接着面８５とは、非接着面８５の全体を上下方向に互いに対向させて配されている。このように基端部６４と折り返し縁部６６の両方に非接着面８５を向かい合わせて設けることにより、表皮側縁部６３の折り返し縁部６６によれた形状や皺が形成される場合でも、そのよれた形状や皺に起因して表皮部材６０の意匠面となる外面に凸部（凸形状）が表出することをより効果的に防止又は抑制できる。 In this embodiment 2, the non-adhesive surface 85 of the base end portion 64 and the non-adhesive surface 85 of the folded edge portion 66 are formed with the same or approximately the same area. Furthermore, the entire non-adhesive surface 85 of the base end portion 64 and the non-adhesive surface 85 of the folded edge portion 66 are arranged facing each other in the vertical direction. By providing non-adhesive surfaces 85 facing each other on both the base end portion 64 and the folded edge portion 66 in this way, even if wrinkles or distortions form on the folded edge portion 66 of the skin side edge portion 63, it is possible to more effectively prevent or suppress the appearance of protrusions (convex shapes) on the outer surface of the skin member 60, which is the design surface, due to these wrinkles or distortions.
なお本発明において、表皮側縁部６３の基端部６４と折り返し縁部６６の両方に非接着面８５を設ける場合、基端部６４の非接着面８５と折り返し縁部６６の非接着面８５とは、非接着面８５の全体で上下方向に互いに対向させるのではなく、少なくとも一部の領域で上下方向に互いに対向するように配されていてもよい。 In this invention, when non-adhesive surfaces 85 are provided on both the base end portion 64 and the folded edge portion 66 of the epidermal side edge portion 63, the non-adhesive surfaces 85 of the base end portion 64 and the non-adhesive surfaces 85 of the folded edge portion 66 may be arranged so that they face each other vertically in at least a portion of their respective regions, rather than having the entire non-adhesive surface 85 facing each other vertically.
本実施例２の加飾縫製部８７は、表皮側縁部６３の基端部６４と折り返し縁部６６とを縫い合わせるように形成されている。この場合、加飾縫製部８７は、基端部６４及び折り返し縁部６６における左右方向の中央部に配されている。本実施例２では、表皮側縁部６３の折り返し縁部６６が、第１接着層８１の形成部分と非接着面８５となる部分の両方が形成可能なように左右方向に長く形成されている。このように折り返し縁部６６が左右方向に長く形成されていることにより、表皮側縁部６３の基端部６４と折り返し縁部６６とに対して縫製加工を容易に施すことができ、それによって、加飾縫製部８７を安定して形成することができる。 In this embodiment 2, the decorative stitched portion 87 is formed by sewing together the base end portion 64 and the folded edge portion 66 of the outer surface side edge portion 63. In this case, the decorative stitched portion 87 is positioned in the center of the base end portion 64 and the folded edge portion 66 in the left-right direction. In this embodiment 2, the folded edge portion 66 of the outer surface side edge portion 63 is formed to be long in the left-right direction so that both the portion for forming the first adhesive layer 81 and the portion for forming the non-adhesive surface 85 can be formed. Because the folded edge portion 66 is formed to be long in the left-right direction, sewing can be easily performed on the base end portion 64 and the folded edge portion 66 of the outer surface side edge portion 63, thereby enabling the stable formation of the decorative stitched portion 87.
このような加飾縫製部８７が、表皮部材６０の外面に表出することにより、表皮部材６０が取り付けられる内装部材を装飾できる。それによって、内装部材の意匠性若しくは装飾性を高めること、又は、内装部材に高級感を与えることができる。なお、加飾縫製部８７の形成位置、形成範囲、及び形成方法等は特に限定されない。また、表皮部材６０は、例えば前述の実施例１のように、加飾縫製部８７を設けずに形成されていてもよい。 The decorative stitching portion 87, when exposed on the outer surface of the skin member 60, can decorate the interior member to which the skin member 60 is attached. This enhances the design or decorative quality of the interior member, or gives it a sense of luxury. The position, range, and method of forming the decorative stitching portion 87 are not particularly limited. Furthermore, the skin member 60 may be formed without the decorative stitching portion 87, as in the previously described embodiment 1.
上述のような本実施例２の表皮部材６０を基材部１０に取り付けることによって内装部材が製造される。このように製造された内装部材では、第１表皮片６１ａ及び第２表皮片６１ｂの各表皮側縁部６３に、第１接着層８１と非接着面８５とが設けられている。このため、表皮側縁部６３の略Ｕ字状に折り曲げられた形状を安定して保持できる。それと同時に、上述したように、表皮側縁部６３の折り返し縁部６６によれた形状や皺が形成される場合でも、そのよれた形状や皺に起因して表皮部材６０の外面に凸部が表出することをより効果的に防止又は抑制できる。従って、本実施例２の表皮部材６０を用いることによって、内装部材の外観品質が低下することを防止又は抑制して、良好な見栄え又は優れた外観性を備えた内装部材を提供することが可能となる。 The interior component is manufactured by attaching the surface member 60 of this embodiment 2, as described above, to the base material 10. In the interior component manufactured in this way, a first adhesive layer 81 and a non-adhesive surface 85 are provided on each surface edge 63 of the first surface piece 61a and the second surface piece 61b. Therefore, the substantially U-shaped folded form of the surface edge 63 can be stably maintained. At the same time, as described above, even if wrinkles or distortions form on the folded edge 66 of the surface edge 63, the appearance of protrusions on the outer surface of the surface member 60 due to these distortions or distortions can be more effectively prevented or suppressed. Therefore, by using the surface member 60 of this embodiment 2, it is possible to prevent or suppress a decrease in the appearance quality of the interior component, and to provide an interior component with a good appearance or superior aesthetics.
なお、上述した実施例１及び実施例２では、凹溝部１２が設けられた基材部１０に表皮部材２０，６０の一部（具体的には、表皮側縁部２３，６３の一部）を挿入して収容するとともに、その表皮部材２０，６０を基材部１０に被せるようにして表皮部材２０，６０が基材部１０に取り付けられている。しかし本発明では、表皮部材の一部を収容する凹溝部を設けずに基材部が形成されていてもよい。すなわち、本発明の表皮部材は、表皮部材の一部を収容する構造で形成された基材部に取り付けて使用することも可能であり、また、表皮部材を収容しない構造で形成された基材部に取り付けて使用することも可能である。 In the above-described embodiments 1 and 2, a portion of the surface material members 20 and 60 (specifically, a portion of the surface material side edges 23 and 63) is inserted into and housed in the base material 10 provided with the groove portion 12, and the surface material members 20 and 60 are attached to the base material 10 by covering the base material 10 with the surface material members 20 and 60. However, in the present invention, the base material may be formed without providing a groove portion to house a portion of the surface material. That is, the surface material member of the present invention can be used attached to a base material formed with a structure that houses a portion of the surface material member, or it can be used attached to a base material formed with a structure that does not house the surface material member.
更に、上述した実施例１及び実施例２では、表皮部材２０，６０を形成する第１表皮片２１ａ，６１ａと第２表皮片２１ｂ，６１ｂの両方が、第１接着層４１，８１が設けられた表皮側縁部２３，６３を有している。しかし、本発明は、表皮部材を形成する第１表皮片と第２表皮片の何れか一方のみが、第１接着層が設けられた表皮側縁部を有する場合にも適用可能である。 Furthermore, in the above-described embodiments 1 and 2, both the first epidermal pieces 21a, 61a and the second epidermal pieces 21b, 61b forming the epidermal members 20, 60 have epidermal side edges 23, 63 on which the first adhesive layers 41, 81 are provided. However, the present invention is also applicable when only one of the first or second epidermal pieces forming the epidermal member has an epidermal side edge on which the first adhesive layer is provided.
