In the vehicle seat in which the frame portion of the skin member is not bonded, the mask
The purpose is to eliminate defects caused by film.

以上の目的を達成するための本発明は略平面状の表面に形成した中央部の左右に隆起状の土手部を一体に有する発泡体製のパッドと、このパッドの中央部表面を被覆する身頃部と、この身頃部に接ぎ合わせて前記土手部の表面を被覆する額縁部とを有する表皮部材とから構成し、前記パッドの中央部表面に液状の接着剤を噴射状に塗布して、パッドの土手部への表皮部材の額縁部の接着を伴うことなく前記表皮部材の身頃部のみをパッドの中央部表面に接着してなる車両用シートにおいて、
額縁部と身頃部とを一体に接ぎ合わせる際に、その一端を同時に額縁部側に一体に縫着することにより、前記接着剤の塗布時に土手部側表面に付着した接着剤により前記パッドに接着される接着布を、表皮部材の額縁部との非接着状態でその内側の身頃部側に配設してなる構成である。 To achieve the above object, the present invention provides a foam pad integrally having a raised bank portion on the left and right sides of a central portion formed on a substantially planar surface, and a body covering the central surface of the pad. And a skin member having a frame part that contacts the body part and covers the surface of the bank part, and a liquid adhesive is sprayed on the surface of the center part of the pad to form a pad. In the vehicle seat formed by adhering only the body part of the skin member to the center surface of the pad without adhering the frame part of the skin member to the bank part of
When the frame part and the body part are joined together, one end of the frame part and the body part are sewn together at the same time on the frame part side so that it adheres to the pad with the adhesive attached to the bank side surface when the adhesive is applied. It is the structure formed by arrange | positioning the adhesive cloth made by the body part side of the inner side in the non-adhesion state with the frame part of an outer skin member .

また、前記接着布は額縁部と身頃部とを一体に接ぎ合わせる際に、同時に額縁部側に一体に縫着するのが好ましい。 Further, it is preferable that the adhesive cloth is integrally sewn to the frame portion side at the same time when the frame portion and the body portion are joined together.

本発明によれば、液状の接着剤をパッドの中央部に塗布した後、そのパッドの表面に表皮部材を被覆して成形型で加圧して表皮部材を接着することにより、パッドの土手部に付着した接着剤に接着布が接着されるが、表皮部材の額縁部はパッドの土手部に接着されない。 According to the present invention, the liquid adhesive is applied to the center of the pad, and then the surface of the pad is covered with a skin member and pressed with a mold to adhere the skin member to the bank of the pad. Although the adhesive cloth is bonded to the adhered adhesive, the frame portion of the skin member is not bonded to the bank portion of the pad.

従って、前記マスキングフィルムを使用した従来品の如き、表皮部材の額縁部に皺が発生しない。また、表皮部材を成形型でパッドに圧着して接着する際の表皮部材を成形型にセットする工数を削減できる。 Therefore, unlike the conventional product using the masking film, wrinkles are not generated in the frame portion of the skin member. Further, it is possible to reduce the number of steps for setting the skin member on the molding die when the skin member is pressure-bonded to the pad with the molding die.

以下、本発明の実施例の一例を図面に基づいて説明する。
図示する車両用シートは、図４に示す自動車用シートのシートバックＳＢ、シートクッションＳＣで、モールド加工した発泡体製パッド２は表皮部材１０、１１、１２で被覆され、フレーム(不図示)に支持されている。 Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.
The vehicle seat shown in the figure is a seat back SB and a seat cushion SC of an automobile seat shown in FIG. 4, and the foam pad 2 molded is covered with skin members 10, 11 and 12, and is attached to a frame (not shown). It is supported.

そして、シートバックＳＢ、シートクッションＳＣを構成するパッドは図５に示すように着座面側の中央部２０表面が略平面状に、この中央部２０の左右に有する土手部２１、２１が隆起状にモールド成形されている。 And as for the pad which comprises seat back SB and seat cushion SC, as shown in FIG. 5, the center part 20 surface by the side of a seating surface is substantially planar shape, and the bank parts 21 and 21 which this center part 20 has right and left are raised shape. Is molded.

そして、中央部２０と土手部２１との境界には、喰込溝２Ａが設けてある。
このパッド２の中央部２０表面に表皮部材の身頃部２０を接着し、土手部２１表面に表皮部材の額縁部１１を接着せずに土手部２１を被覆する。 A biting groove 2A is provided at the boundary between the central portion 20 and the bank portion 21.
The body part 20 of the skin member is bonded to the surface of the center part 20 of the pad 2, and the bank part 21 is covered without bonding the frame part 11 of the skin member to the surface of the bank part 21.

以上の額縁部１１には、まち部１１Ａが一体に延設され、額縁部１１と身頃部１０は一体に接ぎ合わせてあり、この額縁部１１、１１と身頃部１０とをミシンで接ぎ合わせる際、金巾などの布部材からなる接着布１２を同時に縫着する。 The frame portion 11A is integrally extended to the frame portion 11, and the frame portion 11 and the body portion 10 are joined together. When the frame portions 11, 11 and the body portion 10 are joined together by a sewing machine. The adhesive cloth 12 made of a cloth member such as a gold width is sewn simultaneously.

この接着布１２は前記パッド２の中央部２０表面に塗布した接着剤イに対して接着可能な部材で、額縁部１１との非接着状態でその内側の身頃部１０側に配設する。
The adhesive cloth 12 is a member that can be bonded to the adhesive a applied to the surface of the central portion 20 of the pad 2 and is disposed on the inner body 10 side in an unbonded state with the frame portion 11.

以上のパッド２に付着する接着剤イは、ロボットなどで噴射して塗布する液状タイプのものを使用する。そのため、図１、図５に示すように、パッド２の中央部２０のみに接着剤イを塗布しようとしても、土手部２１、２１の中央部２０側に接着剤イが飛散して付着する。 The adhesive a attached to the pad 2 is a liquid type that is sprayed and applied by a robot or the like. Therefore, as shown in FIGS. 1 and 5, even if the adhesive agent A is applied only to the central portion 20 of the pad 2, the adhesive agent i scatters and adheres to the central portion 20 side of the bank portions 21 and 21.

以上の接着剤イを付着したパッド２に表皮部材１０、１１，１１を接着するには、図１に示すように成形型３に表皮部材１０，１１，１１を裏返して載置して成形型３を上昇させるか、或いは、パッド２を加圧型で下降させて両者を圧着させて表皮部材の身頃部１０をパッド２の中央部２０に接着させる。 In order to bond the skin members 10, 11, and 11 to the pad 2 to which the adhesive a is attached, the skin members 10, 11, and 11 are placed on the molding die 3 as shown in FIG. 3 is raised, or the pad 2 is lowered by a pressurizing die and both are pressed to bond the body part 10 of the skin member to the central part 20 of the pad 2.

その際、表皮部材の身頃部１０と額縁部１１との接ぎ合わせ個所１Ａは、喰込溝２Ａ内に成形型３の突片３０によって喰い込まれて接着される。
また、図２、図３に示すように、土手部２１に付着した接着剤イによって接着布１２が土手部２１に接着される。 At that time, the joining portion 1A between the body part 10 and the frame part 11 of the outer skin member is bitten by the projecting piece 30 of the mold 3 into the biting groove 2A and bonded thereto.
In addition, as shown in FIGS. 2 and 3, the adhesive cloth 12 is bonded to the bank portion 21 by the adhesive a attached to the bank portion 21.

従って、表皮部材の額縁部１１、１１はパッド２の土手部２１、２１には接着されないため、表皮部材の額縁部１１、１１が硬くならず、感触が良好となる。 Therefore, since the frame parts 11 and 11 of the skin member are not bonded to the bank parts 21 and 21 of the pad 2, the frame parts 11 and 11 of the skin member do not become hard and the touch is good.

また、接着布１２がパッド２の土手部２１に接着されていたるめ、シートを長期使用しても、接着布１２が身頃部１０方向にズレることはない。 Moreover, even if the adhesive cloth 12 is glued to the bank portion 21 of the pad 2 and the sheet is used for a long time, the adhesive cloth 12 does not shift in the direction of the body part 10.
