Summary of the Invention

Problems to be Solved by the Invention

[0004] When the upper end portion of the terminal portion in the seat width direction of the carpet provided on the back surface of the seat back is sewn to the upper end portion of the side hem of the trim cover, the terminal portion of the carpet may be folded and sewn below the seat back from the sewing portion. In that case, there is a difference in rigidity between the portion of the carpet that is folded and sewn and the portion that is not folded and sewn, and the portion that is not folded and sewn is likely to be deformed, so wrinkles are generated in that portion. In addition, the boundary between the portion of the carpet that is sewn to the side hem and the portion that is not sewn but folded and sewn is likely to be torn when the trim cover is covered.

[0005] An object of the present invention is to obtain a seat back cover for a rear seat and a rear seat that can reduce the difference in rigidity of the terminal portion in the seat width direction of a carpet provided on the back surface of the seat back in a configuration where the upper end portion of the terminal portion in the seat width direction of the carpet is sewn to the upper end portion of the side hem of the trim cover.

Means for Solving the Problems

[0006] The seat back cover of the rear seat according to the first aspect includes a trim cover that is placed over the seat back pad of the rear seat back and has a side mat that covers the side surface of the seat back pad, and a carpet that is disposed on the back surface of the seat back, has a sewing portion sewn to the upper end of the terminal portion in the seat width direction with the upper end of the side mat, and has a folded portion where the terminal portion is folded, and the upper end of the folded portion is arranged side by side inside the seat width direction with respect to the sewing portion.

[0007] According to the seat back cover of the rear seat of the first aspect, the trim cover placed over the seat back pad of the rear seat back has a side mat that covers the side surface of the seat back pad. The carpet disposed on the back surface of the seat back has a sewing portion sewn to the upper end of the terminal portion in the seat width direction with the upper end of the side mat. This carpet has a folded portion where the above terminal portion is folded. The upper end of this folded portion is arranged side by side inside the seat width direction with respect to the above sewing portion. That is, at the terminal portion of the carpet in the seat width direction, a folded portion is also provided at the height where the above sewing portion is arranged. Thereby, the rigidity difference of the above terminal portion can be reduced.

[0008] The seat back cover of the rear seat according to the second aspect is, in the first aspect, the folded portion has a folded-back portion where a part of the terminal portion is folded back toward the main body portion side of the carpet, and the folded-back portion is divided in the vertical direction of the seat back by a cut provided below the seat back with respect to the sewing portion.

[0009] According to the seat back cover of the rear seat in the second aspect, the folding seam portion provided at the terminal portion in the seat width direction of the carpet has a folded-back portion where a part of the terminal portion is folded back toward the main body portion side of the carpet. This folded-back portion is divided in the vertical direction of the seat back by a cut provided on the lower side of the seat back than the sewing portion provided at the terminal portion. Thereby, the folding position of the folded-back portion can be changed between the upper side and the lower side of the seat back with respect to the cut. As a result, for example, the degree of freedom in the arrangement in the seat width direction between the sewing portion and the folding seam portion is improved, and the appearance of the terminal portion in the seat width direction of the carpet becomes good.

[0010] In the seat back cover of the rear seat in the third aspect, in the first aspect or the second aspect, a slit cut from the upper end of the carpet toward the lower end side of the carpet is formed in the upper part of the folded-back portion, and at the upper part and the vertical intermediate part of the sewing portion, the terminal portion of the carpet is sewn to the side mat in a single sheet state, and at the lower part of the sewing portion, the terminal portion is sewn to the side mat in a state of being folded in two layers.

[0011] In the seat back cover of the rear seat in the third aspect, a slit cut from the upper end of the carpet toward the lower end side of the carpet is formed in the upper part of the folded-back portion of the folding seam portion provided at the terminal portion in the seat width direction of the carpet. And at the upper part and the vertical intermediate part of the sewing portion provided at the terminal portion, the terminal portion is sewn to the side mat in a single sheet state. Thereby, the sewing work of the sewing portion becomes easy. Also, at the lower part of the sewing portion, the terminal portion is sewn to the side mat in a state of being folded in two layers. Thereby, it becomes easy to prevent the carpet from being torn at the lower part of the sewing portion when covering the seat back cover.

[0012] The vehicle seat in the fourth aspect includes a seat cushion on which a vehicle occupant sits and a seat back cover of the rear seat in any one of the first aspect to the third aspect, and includes a seat back that supports the back of the occupant.

[0013] In the vehicle seat according to the fourth aspect, the back of the occupant sitting on the seat cushion is supported by the seat back. Since this seat back has the seat back cover of the rear seat according to any one of the first to third aspects, the above-described effects can be obtained.

Advantages of the Invention

[0014] As described above, in the seat back cover and the rear seat according to the present invention, in a configuration in which the upper end portion of the terminal portion in the seat width direction of the carpet provided on the back surface of the seat back is sewn to the upper end portion of the side margin of the trim cover, the difference in rigidity of the terminal portion in the seat width direction of the carpet can be reduced.

Mode for Carrying Out the Invention

[0016] Hereinafter, the rear seat 10 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7. In each figure, some reference numerals may be omitted for ease of viewing the drawings. Also, the arrows FR, RH, and UP appropriately shown in each figure indicate the front, right, and upper directions of the rear seat 10, respectively.

[0017] As shown in FIGS. 1 and 2, the rear seat 10 according to the present embodiment is, for example, a second-row seat of a vehicle and is for three passengers. This rear seat 10 includes a seat cushion 12 on which the occupant sits and a seat back 14 that supports the occupant's back. As shown in FIGS. 1 to 3, the seat back 14 is of a 6:4 split-foldable type and is divided into a left seat back 14L and a right seat back 14R. Hereinafter, the front-rear, upper-lower directions regarding the left seat back 14L and the right seat back 14R indicate the directions in a state where the left seat back 14L and the right seat back 14R are erected (the state shown in FIGS. 1 and 2).

[0018] The left seat back 14L and the right seat back 14R each have a seat back frame 16 which is a skeletal member, a seat back pad 20 supported by the seat back frame 16, and a seat back cover 30 covering the seat back pad 20. Since the left seat back 14L and the right seat back 14R are basically symmetrically configured except that the dimensions in the left-right direction (seat width direction) are different, the right seat back 14R will be described below. In the following description, the right seat back 14R is simply referred to as the "seat back 14R".

[0019] The seat back frame 16 of the seat back 14R is composed of a frame body (not shown) formed in a frame shape when viewed from the front-rear direction, and a rear panel 18 (see FIG. 3) which is formed in a substantially rectangular shape when viewed from the front-rear direction and has the front-rear direction as the plate thickness direction, and is fixed to the rear side of the frame body. The frame body is configured by, for example, combining a press-formed metal plate material or a metal pipe material, and the rear panel 18 is composed of, for example, a press-formed metal plate material. This seat back frame 16 is connected to a vehicle body floor portion (not shown) via a pair of left and right hinges (not shown).

[0020] The seat back pad 20 is composed of, for example, a foam such as urethane foam, and is attached to the seat back frame 16 from the front side. The seat back cover 30 has a trim cover 32 covering the seat back pad 20 and a carpet 36 disposed on the back surface of the seat back 14. The trim cover 32 is configured in a bag shape by sewing a plurality of skin pieces made of, for example, a cloth material, leather, or synthetic leather. As shown in FIG. 3, the left edge portion, right edge portion, and lower edge portion of the trim cover 32 extend to the back side of the seat back 14. This trim cover 32 has a side mat 34 (see FIG. 4) covering the left side surface of the seat back pad 20.

[0021] The carpet 36 is made of, for example, a non-woven fabric, and is formed in a planar shape that is substantially rectangular when viewed from the front-rear direction and has the front-rear direction as the thickness direction. The upper edge portion of the carpet 36 is sewn to the upper edge portion of the trim cover 32. A J-hook 38 is attached to the lower edge portion of the carpet 36 by means such as sewing. The J-hook 38 is a locking tool formed in a J-shaped cross-section by resin. A J-hook 40 similar to the above J-hook 38 is attached to the lower edge portion of the trim cover 32. By engaging these J-hooks 38 and 40, the lower edge portion of the carpet 36 is locked to the lower edge portion of the trim cover 32. The left and right edge portions of the carpet 36 are locked to the left and right edge portions of the trim cover 32 by hook-and-loop fasteners 42 and 44.

[0022] As shown in FIG. 4, a sewing portion 46 sewn to the upper end portion of the side margin 34 of the trim cover 32 is provided at the upper end portion of the left end portion 36A, which is the terminal portion in the sheet width direction of the carpet 36. This sewing portion 46 is provided only at the upper end portion of the left end portion 36A of the carpet 36 and extends in the vertical direction of the seat back 14R.

[0023] Further, a folded portion 48 (see FIGS. 4 and 5) in which the left end portion 36A of the carpet 36 is folded is provided at the left end portion 36A of the carpet 36. This folded portion 48 extends in the vertical direction of the seat back 14R and extends from the upper end to the lower end of the carpet 36. The upper end portion of the folded portion 48 is arranged side by side inside the sewing portion 46 in the sheet width direction. This folded portion 48 has a folded-back portion 37 in which a part of the left end portion 36A is folded back toward the main body portion 36B side of the carpet 36. In FIG. 5, the side margin 34 is not shown.

[0024] The above-mentioned folding portion 37 is divided in the vertical direction of the seat back 14R by a cut 50 (see FIGS. 6 and 7) disposed below the sewing portion 46 on the lower side of the seat back 14R. This cut 50 is inclined so as to go toward the upper end side of the carpet 36 toward the tip side (the left side in FIG. 6). At the tip side of this cut 50, as shown in FIG. 6, the cut 50 is enlarged toward the upper end side of the carpet 36, and a substantially triangular hole 52 is formed. Note that in FIG. 7, the side mat 34 is not shown.

[0025] In the above-mentioned folding portion 37, an upper portion 37A (hereinafter referred to as "upper folding portion 37A") located on the upper end side of the carpet 36 rather than the cut 50 is formed with a slit 54 cut from the upper end of the carpet 36 toward the lower end side of the carpet 36. This upper folding portion 37A is folded back toward the main body portion 36B along the broken line L1 shown in FIGS. 6 and 7. In the above-mentioned folding portion 37, the portion located on the lower end side of the carpet 36 rather than the cut 50 is folded back toward the main body portion 36B along the broken line L2 shown in FIGS. 6 and 7. This broken line L2 is disposed on the right side (the inner side in the seat width direction; the outer side in the vehicle width direction) rather than the above-mentioned broken line L1. And by forming the above-mentioned hole 52 at the left end portion 36A, a step is formed at the left end portion 36A at the lower end of the sewing portion 46 (see FIG. 7).

[0026] As shown in FIGS. 4 and 7, at the upper portion and the vertical intermediate portion of the sewing portion 46 located at the same height as the slit 54, the left end portion 36A of the carpet 36 is sewn to the side mat 34 in a single sheet state. On the other hand, as shown in FIG. 7, at the lower portion 46A of the sewing portion 46 located below the slit 54, the left end portion 36A is sewn to the side mat 34 in a state of being folded in two layers.

[0027] In the seat back 14R of the rear seat 10 configured as described above, the seat back pad 20 is covered with a seat back cover 30 having a trim cover 32 and a carpet 36. The trim cover 32 has a side margin 34 that covers the left side surface of the seat back pad 20, and at the upper end of the left end portion 36A of the carpet 36, a sewing portion 46 sewn to the upper end of the side margin 34 is provided. Further, this carpet 36 has a folded portion 48 where the left end portion 36A is folded. The upper end of this folded portion 48 is arranged side by side on the right side (inside in the seat width direction; outside in the vehicle width direction) with respect to the above-described sewing portion 46.

[0028] That is, at the left end portion 36A of the carpet 36, the folded portion 48 is also provided at the height where the sewing portion 46 is arranged. Thereby, the difference in rigidity of the left end portion 36A can be reduced. As a result, it is possible to prevent wrinkles from occurring at the left end portion 36A and the left end portion 36A from being torn when the trim cover 32 is covered.

[0029] The above effect will be supplemented and explained using the comparative examples shown in FIGS. 8 to 12. In FIGS. 8 to 12, the same reference numerals are given to the same configurations as in the present embodiment. In this comparative example, as shown in FIG. 8, the upper end of the left end portion 36A of the carpet 36 and the upper end of the side margin 34 of the trim cover 32 are sewn at the sewing portion 46. Below the seat back 14 from this sewing portion 46, as shown in FIG. 9, the left end portion 36A is folded at the folded portion 48. This folded portion 48 is not provided at the height where the sewing portion 46 is located. FIG. 10 shows a partial development view of the carpet 36 according to the comparative example. In this FIG. 10, the illustration of the side margin 34 is omitted.

[0030] In this comparative example, there is a difference in rigidity between the portion that is folded and sewn and the portion that is not folded and sewn at the left end portion 36A. Since the upper end portion that is not folded and sewn is likely to be deformed, wrinkles may occur at the upper end portion (see FIG. 11). Further, the boundary between the portion sewn to the side gusset 34 and the portion folded and sewn without being sewn at the left end portion 36A is likely to be torn when the trim cover 32 is covered (see FIG. 12). On the other hand, in the present embodiment, it is possible to prevent the occurrence of wrinkles and the tearing of the carpet 36 as described above.

[0031] Further, the above-described folded portion 48 has a folded-back portion 37 that is folded back toward the main body portion 36B side of the carpet 36 and sewn to the main body portion 36B. This folded-back portion 37 is divided in the vertical direction of the seat back 14R by a cut 50 disposed below the seat back 14R from the above-described sewing portion 46. Thereby, the folding position (the position in the left-right direction of the fold lines L1 and L2) of the folded-back portion 37 can be changed between the upper side and the lower side of the seat back 14R with respect to the cut 50. As a result, for example, the degree of freedom in the arrangement in the left-right direction (seat width direction) of the sewing portion 46 and the folded portion 48 is improved, and the appearance of the left end portion 36A of the carpet 36 becomes good.

[0032] Further, in the present embodiment, the fold line L2 is disposed on the right side (inside in the seat width direction; outside in the vehicle width direction) of the fold line L1, and a hole 52 is formed in the left end portion 36A, so that a step is formed in the left end portion 36A at the lower end of the sewing portion 46 (see FIG. 7). Since this step serves as the end point of the sewing portion 46, the workability of the sewing operation of the sewing portion 46 becomes equivalent to that of the above-described comparative example.

[0033] Further, the upper return portion 37A, which is the upper part of the return portion 37, is separated from the main body portion 36B of the carpet 36 by a slit 54 cut from the upper end of the carpet 36 toward the lower end side of the carpet 36. At the upper part and the middle part in the vertical direction of the sewing portion 46, the left end portion 36A is sewn to the side mat 34 in a single layer state. This facilitates the sewing operation of the sewing portion 46. At the lower part of the sewing portion 46, the left end portion 36A is sewn to the side mat 34 in a state of being folded in two layers. This further makes it easier to prevent the carpet 36 from being torn at the lower part of the sewing portion 46 when the seat back cover 30 is being covered.

[0034] Note that in the above embodiment, the carpet 36 is configured with the slit 54 formed therein, but it is not limited to this, and a configuration in which the slit 54 is not formed in the carpet 36 may also be used. In that case, in the range from the upper part to the lower part of the sewing portion 46, the left end portion 36A is sewn to the side mat 34 in a state of being folded in two layers.

[0035] Also, in the above embodiment, the carpet 36 is configured with the cut 50 formed therein, but it is not limited to this, and a configuration in which the cut 50 is not formed may also be used. In that case, the fold line L1 and the fold line L2 are connected in a straight line.

[0036] In addition, the present invention can be implemented with various modifications without departing from the gist thereof. Needless to say, the scope of rights of the present invention is not limited to the above embodiment.
