By the way, in the known technology, the front seat part and the rear seat part (movable part and fixed part) are each covered with a separate skin (cover part). Therefore, when the front seat part is moved forward, a gap is created between the front seat part and the rear seat part, and there is a risk that the interior of the seat may be excessively exposed through this gap. However, it is also conceivable to provide a skin so as to hide the gap between the front seat surface and the rear seat surface. However, in this case, there is concern that when the front seat is moved rearward, the outer skin (extra length) that covered the gap will loosen, making the shape unstable and causing wrinkles. be done. The present invention has been devised in view of the above-mentioned points, and the problem to be solved by the present invention is to cover a support part having a fixed part and a movable part with a cover part so as to look as good as possible.

It can be roughly divided into a left gap concealing part 23 provided on the slant surface 4d. The upper gap hidden portion 21 is formed in a band shape extending in the left-right direction, and generally crosses the seating surfaces 4a of the fixed portion 10A and the movable portion 10B in the left and right directions. This upper gap hidden portion 21 can be formed by a part of the cover piece SP0 that covers the seating surface 4a shown in FIG. 3, or can also be formed by a part of a plurality of cover pieces.

Further, the right gap hiding part 22 and the left gap hiding part 23 shown in FIG. 2 correspond to the gap hiding part provided on the peripheral surface of the present invention. These right gap hiding part 22 and left gap hiding part 23 have almost the same basic configuration except that they are provided symmetrically, so the configuration will be explained below using the left gap hiding part 23 as an example. . The left gap concealing portion 23 shown in FIG. 3 is formed in a band shape extending vertically, and generally vertically traverses the left slant surface 4d of the fixed portion 10A and the movable portion 10B. This left gap hidden part 23 is formed of a first cover part 31, a second cover part 32, and an intermediate cover part 33, and is provided with a base part 40 and a plurality of fold parts 51 to 53, which will be described later. There is.

The first cover portion 31 shown in FIG. 3 is a gap concealing portion located on the side of the fixed portion 10A, and can be formed at the rear end portion of the rear cover piece SP1 that covers the fixed portion 10A. The second cover portion 32 is a gap hiding portion located on the side of the movable portion 10B, and can be formed at the rear end portion of the front cover piece SP2 that covers the movable portion 10B. Further, the intermediate cover portion 33 is a triangular gap hiding portion with the bottom side facing the seating surface 4a side, and can be formed by the same-shaped intermediate cover piece SP3. In the left gap hidden part 23, each of the three cover pieces described above is sewn together in a roughly Y-shape, and the first cover part 31 and the second cover part 32 are directly sewn together below the left gap hidden part 23. A seam portion 35 (details will be described later) is formed. Further, on the upper side of the left gap concealing part 23 on the seating side, each end of the first cover part 31 and the second cover part 32 is inclined in a direction away from each other, and the intermediate cover part 33 is sewn between them. ing. That is, the rear edge 33a of the intermediate cover part 33 is sewn to the first cover part 31, and the front edge 33b of the intermediate cover part 33 is sewn to the second cover part 32. The upper edge 33c forming the bottom of the intermediate cover portion 33 is sewn to the upper gap concealing portion 21 described above.

[Suture area and base point area]
Referring now to FIGS. 3 to 5, the cover portion 4S has a plurality of stitching locations where adjacent cover pieces are stitched together using generally the same method. For example, referring to FIG. 4, at a suture portion 35 where the first cover portion 31 and the second cover portion 32 are sutured, both cover portions 31 and 32 are sutured with in-stitch IS in the middle surface shape, and these ends are The parts protrude toward the gap 10G. A base point 40 is formed in the sutured part 35 of this embodiment, and this base point 40 has both cover parts 31 and 32 inward toward the gap 10G between the fixed part 10A and the movable part 10B. This will be the base point for folding. This base point portion 40 is formed by a connecting portion 41 that connects the first cover portion 31 and the second cover portion 32 by drawing them toward each other at these suture portions 35. It is arranged on the outer side of the seat than the stitch IS. As this type of connecting portion 41, a joining member such as a suture, a staple, a hook-and-loop fastener, or a point fastener, or an adhesive layer formed by a method such as adhesion or fusion can be used. For example, in this embodiment, the base portion 40 is formed with a suture thread serving as the connecting portion 41 by pinch sewing the first cover portion 31 and the second cover portion 32 together.

[Fold area]
Further, the left gap hidden part 23 shown in FIG. 3 is provided with a plurality of fold parts (back fold part 51, front fold part 52, middle fold part 53) to facilitate inward folding. I can do it. Here, the middle fold part 53 is a part that becomes a crease when the middle cover part 33 is folded inward, which will be described later, and as shown in FIGS. 8 and 9, the middle cover part 33 is moved downward away from the seating surface 4a. It is provided to allow it to fold inward. The middle fold part 53 shown in FIG. 3 extends linearly upward from the apex of the middle cover part 33 on the side of the seam 35, and is formed vertically (in a perpendicular shape) across the middle cover part 33. has been done. As this type of middle fold part 53, various configurations that can be used to add a crease to the middle cover part 33 can be adopted, such as a stitch (suture line) with excellent design, a recessed part formed by embossing, etc. (convex part) etc.

Further, the rear fold part 51 and the front fold part 52 shown in FIG. In this case, it becomes a mountain fold line. Similarly to the middle fold part 53, the rear fold part 51 and the front fold part 52 can also adopt various configurations that allow the intermediate cover part 33 to have creases. The rear fold section 51 and the front fold section 52 are formed symmetrically in the front and back with the intermediate cover section 33 in between. That is, the rear fold portion 51 extends vertically at the end of the first cover portion 31 opposite to the stitched portion 35 (the rear end of the intermediate cover portion 33), and traverses the first cover portion 31 vertically. Further, the front fold portion 52 extends vertically at the end of the second cover portion 32 opposite to the stitched portion 35 (the front end of the intermediate cover portion 33), and traverses the second cover portion 32 vertically.

[Inward bending resistance (bending resistance) of the gap concealing part]
Here, in the left gap hidden part 23 shown in FIG. 3, from the viewpoint of ensuring its inward bendability, at least one of the cover parts 31 to 33 should have relatively low rigidity to make it easy to break. can. For example, the left gap concealing portion 23 is formed of a rear cover piece SP1 (first cover portion 31), a front cover piece SP2 (second cover portion 32), and a middle cover piece SP3 (intermediate cover portion 33). Therefore, at least one of the cover pieces SP1 to SP3 of the left gap hidden portion 23 is made to have a lower bending resistance than the cover piece SP0 located on the seating surface 4a (particularly the portion covering the main portion of the top plate). By doing so, the left gap concealing portion 23 becomes relatively easy to bend and deform, resulting in a configuration that contributes to ensuring smooth inward foldability. The difference in bending resistance can be created by changing the material of each cover piece itself, or by changing the number of materials used. For example, when the cover piece SP0 of the seating surface 4a is made of leather, each of the cover pieces SP1 to SP3 of the left gap hidden portion 23 is made of fabric to provide a difference in bending resistance. In addition, the cover piece SP0 on the main part side of the top plate of the seating surface 4a may be provided with an elastic material such as urethane (not shown) on its back side. By omitting (or making it thinner), it is possible to create a difference in bending resistance. The bending resistance of each cover piece can be measured in accordance with JISL 1096 8.21.1A method.

[Positional displacement of movable part relative to fixed part]
In the seat cushion 4 shown in FIGS. 1 and 5, when the movable part 10B is moved forward with respect to the fixed part 10A, a gap 10G is created between these parts 10A and 10B. Therefore, in this embodiment, in consideration of the appearance of the seat, etc., the gap 10G between the movable part 10B and the fixed part 10A is covered with a cover part 4S shown in FIG. 2. In this type of configuration, as shown in FIGS. 5 to 7, when the movable portion 10B is moved rearward, it is necessary to avoid as much as possible the situation where the cover portion 4S has an extra length and wrinkles.

Therefore, with reference to FIGS. 2 and 3, the cover part 4S of the present embodiment has a gap concealing part 20 that is expanded into a planar shape and covers the gap 10G between the movable part 10B and the fixed part 10A in the separated position. It is provided. The gap concealing part 20 is formed with a base part 40 that becomes a base point when folded inward toward the gap 10G between the movable part 10B and the fixed part 10A, and is fixed to the movable part 10B in the adjacent position. It is configured to be accommodated between the parts 10A in an inwardly folded state with the base part 40 as the base point. In this embodiment, the gap 10G between the movable part 10B and the fixed part 10A at the separated position can be covered by the gap concealing part 20 provided on the cover part 4S. Furthermore, in this embodiment, from the viewpoint of maintaining the appearance of the gap concealing part 20, the gap concealing part 20 is folded inward and accommodated between the movable part 10B and the fixed part 10A in the adjacent position. Therefore, the inward folding mode will be specifically explained below, taking as an example the left gap hidden portion 23 located on the left stile surface 4d.

Here, in the left gap hidden portion 23 shown in FIG. 3, the three cover portions 31 to 33 are folded inward in different manners, so first, the manner in which the first cover portion 31 and the second cover portion 32 are folded inward will be explained. do. As the movable portion 10B is moved rearward as shown in FIGS. 5 to 7, the second cover portion 32 follows the movable portion 10B and moves rearward to the first cover portion 31 side. At this time, in the left gap concealing part 23, the first cover part 31 and the second cover part 32 are folded inwards toward the gap 10G side (right side in each figure) by the base part 40 shown in FIGS. 3 and 4. There is a habit attached to it. Therefore, as the movable portion 10B moves backward, the first cover portion 31 and the second cover portion 32 are folded inward toward the gap 10G using the base portion 40 as a base point. In particular, since the first cover portion 31 and the second cover portion 32 are drawn toward the suture portion 35 that protrudes toward the gap 10G at the connecting portion 41 forming the base portion 40, the two cover portions 31, 32 are drawn closer to each other. It can be folded inwards smoothly. Referring to FIG. 8, the first cover part 31 (second cover part 32) has a rear fold part 51 (front fold part 52) which is a mountain fold line when the base part 40 is a valley fold line. As a result, it is folded inward in a more appropriate form. In this way, the first cover part 31 and the second cover part 32 are gradually folded inwards toward the gap 10G as shown in FIG. It will be housed in.

Further, in the left gap concealing portion 23 shown in FIG. 3, the intermediate cover portion 33 located on the seating side is folded inward in a manner different from the cover portions 31 and 32 described above. That is, referring to FIGS. 8 and 9, the intermediate cover portion 33 is inwardly folded downward away from the seating surface 4a, and is folded between the first cover portion 31 and the second cover portion 32 in the inwardly folded state. To go. At this time, the intermediate cover portion 33 is folded inward (in a more appropriate form) so as to be folded in half, using the perpendicularly provided middle fold portion 53 as a crease.

Further, the intermediate cover portion 33 shown in FIG. 3 is connected to the upper gap concealing portion 21 located on the seating surface 4a at an upper edge 33c forming the bottom surface thereof. Therefore, as shown in FIGS. 8 and 9, when the intermediate cover section 33 is folded downward inward so as to be folded in half, the upper gap hidden section 21 connected thereto is also folded downward inward. In the upper gap hidden portion 21, the cover piece SP0 is folded downward in half and closed together, and is accommodated between the movable portion 10B and the fixed portion 10A. In this way, in the gap concealing part 20 of the present embodiment, by folding the intermediate cover part 33 of the left gap concealing part 23 inwards downward, the upper gap concealing part 21 connected thereto is placed between the movable part 10B and the fixed part 10A. can be accommodated. At this time, by making at least a portion of each of the cover parts 31 to 33 of the left gap concealing part 23 relatively low in bending resistance, it becomes possible to further promote the inward folding deformation of the gap concealing part 20.

In this way, when the movable part 10B is in the close position, the gap hiding part 20 (extra length part) shown in FIGS. 7 and 9 is folded inward and accommodated between the fixed part 10A and the movable part 10B. . At this time, the left gap concealing portion 23 is folded inward from the seat width direction toward the gap side and is well accommodated between the fixed portion 10A and the movable portion 10B. Moreover, the upper gap hidden part 21 shown in FIG. 9 is folded inwards below the seat and is well accommodated between the fixed part 10A and the movable part 10B. At this time, by folding the intermediate cover portion 33 inwardly downward rather than in the sheet width direction, it is possible to avoid as much as possible a situation in which the upper gap concealing portion 21 is pulled or loosened in the sheet width direction. The right gap hiding part 22 shown in FIG. 2 is also folded inwards so as to be symmetrical with the left gap hiding part 23, and is accommodated between the fixed part 10A and the movable part 10B. In this way, according to this embodiment, when the movable part 10B is in a close position, the cover part 4S has an excellent appearance by regularly folding the gap concealing part 20 inwards and avoiding excessive loosening as much as possible. The structure will contribute to securing.

As explained above, in this embodiment, the gap 10G between the movable part 10B and the fixed part 10A at the separated position can be covered by the gap concealing part 20 provided on the cover part 4S. In addition, when the movable part 10B is in a close position, the gap concealing part 20 (extra length part) folded inward at the base part 40 is accommodated between the fixed part 10A and the movable part 10B. A situation in which the portion 20 becomes excessively loose can be avoided as much as possible. In particular, by drawing and connecting the first cover part 31 and the second cover part 32 to the suture part 35 protruding toward the gap 10G by the connecting part 41 of the base part 40, these cover parts 31 and 32 can be connected more smoothly. It becomes possible to fold inward toward the gap 10G side. Therefore, according to this embodiment, the seat cushion 4 (supporting part) having the fixed part 10A and the movable part 10B can be covered with the cover part 4S with good appearance.

Furthermore, in this embodiment, the intermediate cover part 33 provided at the left gap hidden part 23 and the like on the peripheral surface of the seat cushion 4 (supporting part) is folded inwards in the direction away from the seating surface 4a to form the first cover part 31. It can be folded between the second cover parts 32. By providing the intermediate fold portion 53 serving as a base point in the intermediate cover portion 33, it becomes possible to fold the intermediate cover portion 33 inward in a more appropriate manner. Further, in this embodiment, when the base point portion 40 is a valley fold line, other fold portions (51, 52) are mountain fold lines, so the first cover portion 31 and the second cover portion 32 are arranged more appropriately. It is possible to fold it inward in a shape that In this embodiment, at least one of the cover parts 31 to 33 forming the gap concealing part 20 is made to have a relatively low bending resistance to make it easier to bend and deform, thereby allowing the gap concealing part 20 to fold inwards more smoothly. becomes possible.

[Modification 1]
Here, the configuration of the gap concealing portion can take various configurations in addition to the above-mentioned configuration. For example, in the cover portion 4S of Modification 1 shown in FIG. 10, as in the first embodiment, a left gap concealing portion 23X is provided in the gap concealing portion 20X. The left gap hidden portion 23X of this modification differs from the first embodiment in that the intermediate cover portion 33X is formed from part of the cover pieces SP1 and SP2 that form the first cover portion 31X and the second cover portion 32X. It's different.

In this modification shown in FIG. 10, all the ends of the first cover part 31X and the second cover part 32X are sewn together with a suture part 35 extending up and down, and a base part 40 is provided in this suture part 35. A pair of front and rear stitch portions ST1 and ST2 are formed from the middle of the stitched portion 35 in the vertical direction, and these stitch portions ST1 and ST2 are inclined in a direction that gradually separates from each other as they move toward the seating surface 4a. By doing so, the intermediate cover portion 33X can be formed between the front and rear stitch portions ST1 and ST2. Further, a portion of the stitched portion 35 that vertically crosses the intermediate cover portion 33X can serve as a middle fold portion 53. In this way, in this modified example, there is no need to separately prepare a cover piece for forming the intermediate cover portion 33X, resulting in a configuration that contributes to simplifying the configuration of the cover portion 4S.

[Modification 2]
Further, in the cover part 4S of the second modification shown in FIG. 11, as in the first modification, a left gap concealment part 23Y is provided in the gap concealment part 20Y, and this left gap concealment part 23Y has almost the same configuration as the first modification. It has respective cover parts 31Y to 33Y. In this modification, instead of the stitching in Modification 1, pinch stitching is performed using suture thread Y1 between the rear edge portion 33A of the intermediate cover portion 33Y and the first cover portion 31Y. Furthermore, pinch stitching is performed using suture thread Y2 between the front edge portion 33B of the intermediate cover portion 33Y and the second cover portion 32Y. By doing so, an intermediate cover portion 33Y can be formed between the front and rear knob stitched portions (each suture thread Y1, Y2). In this modification, the rear edge portion 33A and the front edge portion 33B of the intermediate cover portion 33Y are sewn with pinch stitches, making it possible to serve as a base portion, thereby providing an excellent internal position for the left gap concealing portion 23Y. The structure contributes to ensuring foldability.

[Example 2]
In the vehicle seat 2A of the second embodiment shown in FIG. 12, components having substantially the same basic configuration as the vehicle seat of the first embodiment are designated by corresponding reference numerals, and detailed description thereof will be omitted. The vehicle seat 2A of Example 2 has a seat cushion (not shown), a seat back 6, and a headrest 8 as a basic configuration. are connected via. The present embodiment is different from the first embodiment in that a gap concealing portion 200 of the cover portion 40S is provided to cover the gap between the headrest 8 and the seat back 6. Here, in the vehicle seat 2A, a portion extending from the seat back 6 to the headrest 8 corresponds to a support portion, and can support the head of the occupant from the back. The headrest 8 as the movable part 100B moves up and down with respect to the seat back 6 as the fixed part 100A, thereby being displaced between the close position and the separated position.

Further, the gap concealing portion 200 is formed in a band shape so as to cover the gap between the headrest 8 and the seat back 6. The gap concealing portion 200 can be roughly divided into a first gap concealing portion 210 located on the front (seating surface) and rear surface, and a second gap concealing portion 220 located on the left and right peripheral surfaces (in FIG. 12, for convenience, Only the gap concealing parts on the left peripheral surface and rear surface are shown). Here, the first gap concealing portion 210 corresponds to the upper gap concealing portion of the first embodiment, and is formed in the shape of a long strip in the left-right direction. The first gap concealing portion 210 can be formed by sewing together the end portions of the cover piece SP10 on the seat back side and the cover piece SP11 on the headrest side.

Further, the second gap concealing portion 220 corresponds to the left gap concealing portion of Modification 1, and is formed in the shape of a long strip in the front-rear direction. This second gap concealing part 220 is created by sewing together a first cover part 310 formed by the cover piece SP12 on the seat back side and a second cover part 320 formed by the cover piece SP13 on the headrest side at a seam part 350. It is formed by Further, a pair of intermediate cover parts 330a and 330b are provided on the front end side and the rear end side of the second gap concealing part 220. These pair of intermediate cover portions 330a and 330b are triangular portions formed by a pair of stitches (numerals omitted) as in Modification 1, and the bases of these portions correspond to the corresponding front and rear first gap hiding portions. It is connected to 210.

When the headrest 8 is raised and is in a separated position away from the seat back 6, the gap between them is covered by a gap concealing portion 200 developed in a planar shape. Further, when the headrest 8 is lowered to a position close to the seat back 6, the gap concealing portion 200 is folded inwards (inwardly folded in an accordion shape) and accommodated therebetween. At this time, the first gap concealing portion 210 is folded inward in the front-rear direction of the seat and accommodated between the headrest 8 and the seat back 6. At the same time, the second gap concealing portion 220 is folded inward in the seat width direction and accommodated between the headrest 8 and the seat back 6. Therefore, also in this embodiment, a part (supporting part) of the vehicle seat 2A having the seat back 6 (fixed part 100A) and the headrest 8 (movable part 100B) can be covered with the cover part 40S with a good appearance. .

The vehicle seat of this embodiment is not limited to the embodiment described above, and may take various other embodiments. In the present embodiment, the configuration (shape, size, arrangement position, number of arrangement, etc.) of the gap concealing part is illustrated, but this is not intended to limit the configuration of the gap concealing part. For example, the gap concealing portion can be formed of a resin plate attached to the cover portion. When a plate material is used as the peripheral surface, an integral hinge serving as a base point or a fold portion can be provided on this plate material, and the outer surface thereof can be covered with a cover material. Further, the intermediate cover portion may have an equilateral triangular shape in which the lengths of each side are approximately equal, but the lengths of each side do not necessarily have to be the same. In addition, the shape of each side of the intermediate cover part can be set depending on the relationship with the adjacent cover part. For example, the side that connects to the first cover part or the second cover part may be straight or curved. It may be . Further, the gap concealing portion on the circumferential surface can be formed by one cover piece, and in this case, each cover portion can be provided by a technique such as stitching or pinch stitching. Note that the gap concealing portion may be provided only on the peripheral surface or the seating surface of the support portion, and in this case, the gap concealing portion can be formed by the first cover portion and the second cover portion.

Further, in the present embodiment, an example in which a folded portion is provided in the gap concealing portion has been described, but it is not necessarily necessary to provide a folded portion. For example, the portion corresponding to the crease portion may be bent in advance and a crease may be added. Further, the configurations of each embodiment and each modification can be used in combination as appropriate. For example, it is possible to adopt a configuration in which the gap concealing portion of the first embodiment is folded inward in an accordion shape.

Furthermore, the holding member of this embodiment can be applied to the cover portions of various seat constituent members such as seat backs, headrests, and armrests in addition to seat cushions. Further, although the configuration of the vehicle seat 2 has been illustrated, the configuration of the vehicle seat can be changed as appropriate, and the configuration of this embodiment can be applied to a vehicle seat for multiple people or for one person. The configuration of this embodiment can be applied to general vehicle seats such as vehicles, aircraft, trains, and ships.
