[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-203217 Summary of the Invention [Problem to be solved by the invention]

[0004] When inserting the trim wire into a hanging bag extending in the up-down direction of the seat back, for example, a bent portion formed at the end of the trim wire is hooked onto the upper end of the hanging bag to prevent the trim wire from falling. However, the trim wire may fall off when the trim cover is put on or when the seat is being carried, which requires labor to re-hook the wire.

[0005] An object of the present invention is to provide a trim cover and a vehicle seat that can prevent a trim wire from falling out of a hanging bag. [Means for solving the problem]

[0006] The trim cover of the first embodiment is a trim cover that is placed over a seat back pad in which an insert wire extending in the vertical direction of the seat back is embedded, has a hanging bag extending in the vertical direction, and the trim wire inserted into the hanging bag is connected to the insert wire by a hog ring, and the lower end of the hanging bag is sewn closed.

[0007] The trim cover of the first embodiment is placed on a seat back pad in which an insert wire extending in the vertical direction of the seat back is embedded. This trim cover has a hanging bag extending in the vertical direction of the seat back. The trim wire inserted in the hanging bag is connected to the insert wire by a hog ring. The lower end of the hanging bag is sewn and closed, so that the trim wire can be prevented from falling from the lower end of the hanging bag.

[0008] The trim cover of the second embodiment is a trim cover that is placed over a seat back pad in which an insert wire extending in the vertical direction of the seat back is embedded, has a hanging bag extending in the vertical direction, and the trim wire inserted into the hanging bag is connected to the insert wire by a hog ring, and the lower end of the hanging bag has a first lower diagonal fold stitch portion that is folded and sewn toward the inside of the hanging bag along a direction inclined relative to the horizontal direction of the seat back, and a second lower diagonal fold stitch portion that is folded and sewn toward the inside of the hanging bag along a direction inclined in the opposite direction to the first lower diagonal fold stitch portion, and is positioned opposite to the first lower diagonal fold stitch portion and shifted in the vertical direction.

[0009] The trim cover of the second embodiment is placed on a seat back pad in which an insert wire extending in the vertical direction of the seat back is embedded. This trim cover has a hanging bag extending in the vertical direction of the seat back. The trim wire inserted in this hanging bag is connected to the insert wire by a hog ring. The lower end of the hanging bag has a first lower diagonal fold stitch part that is folded and sewn toward the inside of the hanging bag along a direction inclined relative to the horizontal direction of the seat back, and a second lower diagonal fold stitch part that is folded and sewn toward the inside of the hanging bag along a direction inclined in the opposite direction to the first lower diagonal fold stitch part. Since the second lower diagonal fold stitch part is disposed opposite to the first lower diagonal fold stitch part, the first lower diagonal fold stitch part and the second lower diagonal fold stitch part get in the way, and thus the trim wire can be prevented from falling from the lower end of the hanging bag. In addition, since the second lower diagonal fold seam is positioned offset in the vertical direction of the seat back with respect to the first lower diagonal fold seam, it is easy to insert the trim wire into the hanging bag between the first lower diagonal fold seam and the second lower diagonal fold seam.

[0010] The trim cover of the third embodiment is a trim cover that is placed over a seat back pad in which an insert wire extending in the vertical direction of the seat back is embedded, has a hanging bag extending in the vertical direction, and the trim wire inserted into the hanging bag is connected to the insert wire by a hog ring, and the lower end of the hanging bag has a first lower folded stitch portion that is folded toward the inside of the hanging bag and sewn, and a second lower folded stitch portion that is folded toward the inside of the hanging bag and sewn, faces the first lower folded stitch portion, and is aligned in the vertical direction.

[0011] In the trim cover of the third aspect, a seat back pad in which an insert wire extending in the vertical direction of the seat back is embedded is covered. This trim cover has a hanging bag extending in the vertical direction of the seat back. The trim wire inserted in this hanging bag is connected to the insert wire by a hog ring. The lower end of the hanging bag has a first lower folded stitched portion folded and sewn toward the inside of the hanging bag, and a second lower folded stitched portion folded and sewn toward the inside of the hanging bag. Since the second lower folded stitched portion is arranged opposite to the first lower folded stitched portion, the first lower folded stitched portion and the second lower folded stitched portion get in the way, and thus the trim wire can be prevented from falling from the lower end of the hanging bag. In addition, the second lower folded stitched portion is arranged in line with the first lower folded stitched portion in the vertical direction of the seat back, but is not sewn to the first lower folded stitched portion, so that the trim wire can be inserted (screwed) into the hanging bag between the first lower folded stitched portion and the second lower folded stitched portion.

[0012] The trim cover of the fourth aspect is any one of the first to third aspects above, wherein the upper end of the hanging bag has a first upper diagonal fold stitch portion that is folded toward the inside of the hanging bag along a direction inclined relative to the horizontal direction of the seat back and sewn, and a second upper diagonal fold stitch portion that is folded toward the inside of the hanging bag along a direction inclined in the opposite direction to the first upper diagonal fold stitch portion and sewn, and is positioned opposite the first upper diagonal fold stitch portion and shifted in the vertical direction.

[0013] In the trim cover of the fourth aspect, the upper end of the hanging bag has a first upper diagonal fold and a second upper diagonal fold. The first upper diagonal fold is folded and sewn toward the inside of the hanging bag along a direction inclined relative to the horizontal direction of the seat back. The second upper diagonal fold is folded and sewn toward the inside of the hanging bag along a direction inclined in the opposite direction to the first upper diagonal fold, and is disposed opposite the first upper diagonal fold and shifted in the vertical direction of the seat back. This makes it easy to insert the trim wire into the hanging bag between the first upper diagonal fold and the second upper diagonal fold.

[0014] The trim cover of the fifth aspect is any one of the first to third aspects, in which the upper end of the hanging bag has a first upper folded stitch portion that is folded toward the inside of the hanging bag and sewn, and a second upper folded stitch portion that is folded toward the inside of the hanging bag and sewn, faces the first upper folded stitch portion, and is aligned in the vertical direction.

[0015] In the trim cover of the fifth aspect, the upper end of the hanging bag has a first upper fold stitch portion and a second upper fold stitch portion. The first upper fold stitch portion is folded and sewn toward the inside of the hanging bag. The second upper fold stitch portion is folded and sewn toward the inside of the hanging bag, facing the first upper fold stitch portion and aligned in the vertical direction of the seat back. Since the first upper fold stitch portion and the second upper fold stitch portion are not sewn, it is possible to insert (screw) the trim wire into the hanging bag between the first upper fold stitch portion and the second upper fold stitch portion.

[0016] A vehicle seat of a sixth aspect includes a seat cushion on which an occupant sits and a seat back that supports the back of the occupant, and the seat back includes a seat back pad having an insert wire embedded therein that extends in the vertical direction of the seat back, a trim cover of any one of the first to fifth aspects that covers the seat back pad and has a hanging bag that extends in the vertical direction, and a trim wire that is inserted into the hanging bag and connected to the insert wire by a hog ring.

[0017] In the vehicle seat of the sixth aspect, the back of an occupant seated on the seat cushion is supported by the seat back. The seat back has a seat back pad in which an insert wire extending in the vertical direction is embedded, a trim cover that covers the seat back pad and has a hanging bag extending in the vertical direction, and a trim wire that is inserted into the hanging bag and connected to the insert wire by a hog ring. The trim cover is any one of the first to fifth aspects, and therefore the above-mentioned effects can be obtained. Effect of the Invention

[0018] As described above, the trim cover and the vehicle seat according to the present invention can prevent the trim wire from falling off the hanging bag. [Brief description of the drawings]

[0020] <First embodiment> Hereinafter, a vehicle seat 10 according to a first embodiment of the present invention will be described with reference to Figs. 1 to 8. In each drawing, some reference symbols may be omitted in order to make the drawings easier to see. Arrows FR, LH, and UP, which are appropriately written in each drawing, respectively indicate the front, left, and top of the vehicle seat 10. Hereinafter, when the front-rear, left-right, top-bottom directions are used in the description, they will indicate directions relative to the vehicle seat 10.

[0021] As shown in Fig. 1, a vehicle seat 10 according to this embodiment is, for example, a front seat of a vehicle, and includes a seat cushion 12 on which an occupant sits, a seat back 14 that supports the back of the occupant, and a headrest 16 that supports the head of the occupant. The seat cushion 12 is connected to a floor portion (not shown) of the vehicle via a well-known slide mechanism 18. A lower end portion of the seat back 14 is connected to a rear end portion of the seat cushion 12 via a well-known reclining mechanism 20. The headrest 16 is connected to an upper end portion of the seat back 14 so that its vertical position can be adjusted.

[0022] 1, the front-rear, left-right, up-down and up-down directions of the vehicle seat 10 and the front-rear, left-right, up-down and up-down directions of the seat back 14 are substantially the same. As shown in Fig. 1 and Fig. 2, the seat back 14 has a seat back frame 22 which is a framework member, a seat back pad 26 which is a cushioning material supported by the seat back frame 22, and a trim cover (seat back skin) 32 which is a skin material covered on the seat back pad 26.

[0023] The seatback frame 22 is formed by joining, for example, press-molded metal plate material or metal pipe material, and has a rectangular frame shape when viewed in the front-rear direction. The seatback frame 22 has two left and right side frames 24 extending in the up-down direction of the seatback 14 on the left and right sides of the seatback 14. The seatback pad 26 is formed of a foam such as urethane foam, and covers the seatback frame 22 from the front and upper sides. The seatback pad 26 is elastically supported from the rear side by a plurality of S springs 28 spanning between the left and right side frames 24. Two left and right insert wires 30 are embedded in the back of the seatback pad 26 on the left-right central side of the left and right side frames 24. The left and right insert wires 30 are embedded in the seatback pad 26 by, for example, integral foam molding.

[0024] The trim cover 32 is formed into a bag shape by sewing together a plurality of skin pieces made of, for example, a cloth material, leather, synthetic leather, etc., and is placed over the seat back pad 26. The rear portion of the trim cover 32 is made up of a plurality of skin pieces as shown in Fig. 4. The plurality of skin pieces as shown in Fig. 4 include a rear main skin piece 34 disposed in the center of the rear surface of the seat back 14, two rear side skin pieces 36 disposed on both the left and right sides of the rear main skin piece 34, and two rear hanging skin pieces 38 provided between the left and right rear side skin pieces 36 and the rear main skin piece 34, respectively.

[0025] As shown in FIG. 2, the left and right rear side upholstery pieces 36 and the rear main upholstery piece 34 are sewn at two left and right sewing parts S1 located on both the left and right sides of the rear surface of the seat back 14. As shown in FIG. 3 to FIG. 5, the left and right rear hanging upholstery pieces 38 are substantially trapezoidal. The rear edge parts 38B (see FIG. 5), which are the edges on the bottom side of the substantially trapezoidal shape of the left and right rear hanging upholstery pieces 38, are sewn together with the above-mentioned sewing part S1. The front edge parts 38A (see FIG. 5), which are the edges on the top side of the substantially trapezoidal shape of the left and right rear hanging upholstery pieces 38, are respectively connected to the left and right insert wires 30 of the seat back pad 26 via the trim wires 46 and the hog rings 50. As shown in FIG. 2, the left and right rear hanging upholstery pieces 38 are arranged to be inclined toward the left and right center as they move toward the front side when viewed from the top-bottom direction of the seat back 14. The left and right rear hanging cover pieces 38 are formed in an elongated shape with the vertical direction of the seat back 14 as the longitudinal direction.

[0026] As shown in Fig. 5, the upper edge 38C of the rear hanging skin piece 38 is inclined downward from the bottom side to the top side of the rear hanging skin piece 38, and is inclined with respect to the horizontal direction of the seat back 14. The lower edge 38D of the rear hanging skin piece 38 is inclined upward from the bottom side to the top side of the rear hanging skin piece 38, and is inclined with respect to the horizontal direction of the seat back 14. The upper edge 38C of the rear hanging skin piece 38 is folded in half and sewn at a sewing section S2. The front edge 38A of the rear hanging skin piece 38 is folded in half and sewn at a sewing section S3. This sewing section S3 extends in the vertical direction of the seat back 14, and a hanging bag 40 extending in the vertical direction of the seat back 14 is formed at the front edge 38A of the rear hanging skin piece 38.

[0027] As shown in Figs. 5 and 6, the lower end of the hanging bag 40 is sewn and closed at the sewing portion S4. As shown in Figs. 5 to 7, the upper end of the hanging bag 40 is configured by folding a part of the sewing portion S2 provided on the upper edge portion 38C of the back hanging cover piece 38 in half. The upper end of the hanging bag 40 is configured by a first upper diagonal folding stitch portion 42 folded and sewn toward the inside of the hanging bag 40 along a direction inclined relative to the horizontal direction of the seat back 14 (here, a direction along the upper edge portion 38C), and a second upper diagonal folding stitch portion 44 folded and sewn toward the inside of the hanging bag 40 along a direction inclined in the opposite direction to the first diagonal folding stitch portion 42. The first upper diagonal folding stitch portion 42 and the second upper diagonal folding stitch portion 44 include a part of the sewing portion S2. The second upper diagonal folding stitch portion 44 is disposed opposite (contacting) the first upper diagonal folding stitch portion 42 and shifted in the up-down direction of the seat back 14.

[0028] A trim wire 46 is inserted inside the sling bag 40 configured as described above. The trim wire 46 is made of a metal wire and is disposed inside the sling bag 40 with the vertical direction of the seat back 14 as the longitudinal direction. A bent portion 46A bent into a J shape is formed at both longitudinal ends of the trim wire 46. As shown in FIG. 7, the width dimension W1 of the bent portion 46A is set smaller than the width dimension W2 of the sling bag 40. The length dimension of this trim wire 46 is set shorter than the length dimension of the sling bag 40.

[0029] The trim wire 46 is inserted into the sling bag 40 between the first upper diagonal fold 42 and the second upper diagonal fold 44 at the upper end of the sling bag 40, and the entire trim wire 46 is housed in the sling bag 40. Since the second upper diagonal fold 44 and the first upper diagonal fold 42 are arranged offset in the up-down direction of the seat back 14, the bent portion 46A of the trim wire 46 slides over the first upper diagonal fold 42, guiding the insertion of the trim wire 46 between the first upper diagonal fold 42 and the second upper diagonal fold 44, making the insertion easy (see the arrow IN in FIG. 8).

[0030] The trim wire 46 inserted into the hanging bag 40 is prevented from falling out of the hanging bag 40 by the stitching S4 at the lower end of the hanging bag 40. The trim wire 46 in the hanging bag 40 is prevented from slipping out of the hanging bag 40 by the first upper diagonal fold stitching 42 and the second upper diagonal fold stitching 44 which get in the way (see the arrow OUT in FIG. 8). The back surface of the back hanging skin piece 38 is laminated with a foam (urethane foam, etc.) having a thickness of, for example, about 1 to 3 millimeters, and the first upper diagonal fold stitching 42 and the second upper diagonal fold stitching 44 are thickened. This improves the above-mentioned slip-out prevention effect.

[0031] Two semicircular cutouts 48 are formed at the top and bottom of the hanging bag 40, and a portion of the trim wire 46 is exposed from each of the cutouts 48. Each exposed portion of the trim wire 46 is engaged with the insert wire 30 by a hog ring 50. As a result, the center portion of the rear surface of the trim cover 32 is pulled toward the seat back pad 26 by the left and right rear hanging skin pieces 38, and the leg space of a passenger in the rear seat (not shown) is expanded.

[0032] In the vehicle seat 10 configured as described above, the back of an occupant seated on the seat cushion 12 is supported by the seat back 14. The seat back 14 has a seat back pad 26 in which an insert wire 30 extending in the vertical direction is embedded, a trim cover 32 that covers the seat back pad 26 and has a hanging bag 40 that extends in the vertical direction of the seat back 14, and a trim wire 46 that is inserted into the hanging bag 40 and connected to the insert wire 30 by a hog ring 50.

[0033] In the above trim cover 32, the lower end of the hanging bag 40 is sewn and closed at the sewing portion S4, so that the trim wire 46 can be prevented from falling from the lower end of the hanging bag 40. Moreover, in this trim cover 32, the upper end of the hanging bag 40 has a first upper diagonal fold 42 and a second upper diagonal fold 44. The first upper diagonal fold 42 is folded and sewn toward the inside of the hanging bag 40 along a direction inclined relative to the horizontal direction of the seat back 14. The second upper diagonal fold 44 is folded and sewn toward the inside of the hanging bag along a direction inclined in the opposite direction to the first upper diagonal fold 42, and is disposed opposite to the first upper diagonal fold 42 and shifted in the up-down direction of the seat back 14. Therefore, it is easy to insert the trim wire 46 into the hanging bag 40 from between the first upper diagonal fold 42 and the second upper diagonal fold 44.

[0034] As explained in the section on problems to be solved by the invention, in the conventional measure of preventing the trim wire 46 from falling by hooking the bent portion 46A of the trim wire 46 onto the upper end of the suspending bag 40, the trim wire 46 may fall off when covering the trim cover 32 or when carrying the trim wire 46, resulting in labor required to re-hook the trim wire 46. Other conventional measures include, for example, bending the trim wire 46 to a width equal to that of the suspending bag 40, or entangling the bent portion 46A of the trim wire 46 with the bent portion 46A of another trim wire 46, but these require labor for bending and entangling. In this regard, the present embodiment can prevent the occurrence of unnecessary labor.

[0035] Furthermore, in the measures of hooking the bent portion 46A of the trim wire 46 on the upper end of the suspending bag 40 or entangling the bent portion 46A of one trim wire 46 with the bent portion 46A of another trim wire 46, the bent portion 46A of the trim wire 46 is exposed to the outside of the suspending bag 40, and this exposed portion may come into contact with surrounding components and generate abnormal noise. In this regard, in the present embodiment, the bent portion 46A of the trim wire 46 is not exposed to the outside of the suspending bag 40, but is contained within the suspending bag 40, so that the generation of the above-mentioned abnormal noise can be prevented. Moreover, the length of the trim wire 46 can be set shorter than with each of the above-mentioned measures.

[0036] Furthermore, when the trim wire 46 is made of resin to prevent the above-mentioned abnormal noise, there is a concern that the rigidity of the trim wire 46 is insufficient and the amount of retraction of the rear surface of the trim cover 32 is reduced, making it difficult to ensure leg space for the rear seat passengers and deteriorating the appearance of the seat back 14, but this embodiment can avoid this. Also, in this embodiment, a foam is laminated to the rear surface of the rear surface hanging skin piece 38, making it difficult for the trim wire 46 to move within the hanging bag 40. As a result, the range of displacement of the trim wire 46 during and after hogling is reduced, reducing the risk of deterioration of the appearance of the seat back 14 due to displacement of the trim wire 46.

[0037] Next, another embodiment of the present invention will be described. Note that the same reference numerals as in the first embodiment are given to the configurations and operations that are basically the same as those in the first embodiment, and the description thereof will be omitted.

[0038] <Second embodiment> Fig. 9 shows a rear view of a rear hanging skin piece 38 which is a part of a trim cover according to a second embodiment of the present invention. Fig. 10 shows a cross-sectional view of a cut surface taken along line F10-F10 in Fig. 9. In this embodiment, a lower edge portion 38D of the rear hanging skin piece 38 is folded in half and sewn at a sewing portion S5.

[0039] The lower end of the hanging bag 40 is configured by folding a part of the sewing part S5 provided on the lower edge part 38D of the back hanging skin piece 38 in half. The lower end of the hanging bag 40 is configured by a first lower diagonal folding stitch part 52 folded and sewn toward the inside of the hanging bag 40 along a direction inclined relative to the horizontal direction of the seat back 14 (here, along the lower edge part 38D), and a second lower diagonal folding stitch part 54 folded and sewn toward the inside of the hanging bag 40 along a direction inclined in the opposite direction to the first lower diagonal folding stitch part 52. The first lower diagonal folding stitch part 52 and the second lower diagonal folding stitch part 54 include a part of the sewing part S5. The second lower diagonal folding stitch part 54 faces (here, in contact with) the first lower diagonal folding stitch part 52 and is arranged offset in the up-down direction of the seat back 14. In this embodiment, the configuration other than the above is the same as that of the first embodiment.

[0040] In this embodiment, the first lower diagonal fold 52 and the second lower diagonal fold 54 get in the way, preventing the trim wire 46 from falling out of the suspending bag 40. Also, the trim wire 46 can be easily inserted into the suspending bag 40 from either the upper end or the lower end of the suspending bag 40.

[0041] <Third embodiment> Fig. 11 shows a rear view of a rear hanging upholstery piece 38 which is a part of a trim cover according to a third embodiment of the present invention. Fig. 12 shows a cross-sectional view of a cut surface taken along line F12-F12 in Fig. 11. In this embodiment, a lower edge 38D of the rear hanging upholstery piece 38 is not inclined with respect to the horizontal direction of the seat back 14, but is aligned with the horizontal direction of the seat back 14. This lower edge 38D is folded in half and sewn at a sewing portion S6.

[0042] The lower end of the hanging bag 40 is configured such that a part of the sewn part S6 provided on the lower edge part 38D of the back hanging skin piece 38 is folded in half. The lower end of the hanging bag 40 is configured by a first lower fold stitch part 56 and a second lower fold stitch part 58. The first lower fold stitch part 56 is folded and sewn toward the inside of the hanging bag 40 along the horizontal direction of the seat back 14. The second lower fold stitch part 58 is folded and sewn toward the inside of the hanging bag 40 along the horizontal direction of the seat back 14. The first lower fold stitch part 56 and the second lower fold stitch part 58 include a part of the sewn part S6. The second lower fold stitch part 58 faces (contacts) the first lower fold stitch part 56 and is arranged in the vertical direction of the seat back 14. In this embodiment, the configuration other than the above is the same as that of the first embodiment.

[0043] In this embodiment, the first bottom sewn portion 56 and the second bottom sewn portion 58 get in the way, preventing the trim wire 46 from falling out of the sling bag 40. The second bottom sewn portion 58 is aligned with the first bottom sewn portion 56 in the up-down direction of the seat back 14, but is not sewn to the first bottom sewn portion 56, so that the trim wire 46 can be screwed into the sling bag 40 between the first bottom sewn portion 56 and the second bottom sewn portion 58 (see the arrows IN in Figs. 13 and 14 and the arrow OP in Fig. 14).

[0044] <Fourth embodiment> FIG. 15 shows a rear view of the rear hanging upholstery piece 38, which is a part of the trim cover according to the fourth embodiment of the present invention. FIG. 16 shows a cross-sectional view of a cut surface along the line F16-F16 in FIG. 15. In this embodiment, the lower edge 38D of the rear hanging upholstery piece 38 and the lower end of the hanging bag 40 are configured in the same manner as in the third embodiment. In this embodiment, the upper edge 38C of the rear hanging upholstery piece 38 is not inclined with respect to the horizontal direction of the seat back 14, but is aligned with the horizontal direction of the seat back 14. Therefore, the rear hanging upholstery piece 38 is formed in a rectangular shape. The upper edge 38C is folded in half and sewn at the sewing portion S7.

[0045] The upper end of the hanging bag 40 is configured by folding a part of the sewing part S7 provided on the upper edge part 38C of the back hanging skin piece 38 in half. The upper end of this hanging bag 40 is configured by a first upper folding stitch part 60 and a second upper folding stitch part 62. The first upper folding stitch part 60 is folded and sewn toward the inside of the hanging bag 40 along the horizontal direction of the seat back 14. The second upper folding stitch part 62 is folded and sewn toward the inside of the hanging bag 40 along the horizontal direction of the seat back 14. The first upper folding stitch part 60 and the second upper folding stitch part 62 include a part of the sewing part S7. The second upper folding stitch part 60 faces (contacts) the first upper folding stitch part 60 and is arranged in the vertical direction of the seat back 14. In this embodiment, the configuration other than the above is the same as that of the first embodiment.

[0046] In this embodiment, the first upper sewn portion 60 and the second upper sewn portion 62 get in the way, preventing the trim wire 46 from slipping out from the upper end of the sling bag 40.
