DETAILED DESCRIPTION OF THE INVENTION

[0018] 1 shows a side view of a vehicle seat 10 according to an embodiment of the present invention as seen from the left. In the drawing, the front of the vehicle seat 10 is indicated by an arrow FR, the left of the vehicle seat 10 is indicated by an arrow LH, and the upper side of the vehicle seat 10 is indicated by an arrow UP.

[0019] A vehicle seat 10 in this embodiment is provided in the passenger compartment of a vehicle (automobile).

[0020] As shown in FIG. 1, a seat cushion 12 is provided under a vehicle seat 10, and a vehicle occupant sits on the seat cushion 12. A seat back 14 is provided above the rear end of the seat cushion 12, and the seat back 14 supports the back of the occupant. A headrest 16 is provided above the seat back 14, and the headrest 16 supports the head of the occupant. A pair of rod-shaped stays 16A (see FIG. 6(A)) are fixed to the lower end of the headrest 16, and the stays 16A extend downward. The stays 16A are inserted into the upper part of the seat back 14, and thereby the headrest 16 is supported by the seat back 14. The height of the headrest 16 relative to the seat back 14 can be adjusted by adjusting the amount of insertion of the stays 16A into the seat back 14.

[0021] The seat back is provided with a metal frame-shaped seat back frame (see FIG. 3), which constitutes the framework of the seat back .

[0022] The outer periphery of the seatback frame 18 is covered with a seatback pad 20, which is made of a foam such as foam-molded polyurethane foam. The seatback pad 20 is hollow and open downward, and the seatback frame 18 is fitted into the seatback pad 20 from below. A substantially rectangular opening 22 is formed through the rear (back) of the seatback pad 20, and the opening 22 opens the interior of the seatback pad 20 rearward and downward. A plate-shaped upper flange 24 is formed above the opening 22 at the rear of the seatback pad 20, and plate-shaped side flanges 26 are formed on both left and right outer sides of the opening 22.

[0023] Long slits 28 are formed through the left and right portions of upper flange 24, and slits 28 extend in the up-down direction and communicate with opening 22. Upper flange 24 is divided in the left-right direction by slits 28, and a rectangular plate-shaped hanging portion 24A is formed in the center portion of upper flange 24 in the left-right direction (between the pair of slits 28). When seatback pad 20 is released from the foam molding mold, slits 28 are enlarged by the mold that forms the interior of seatback pad 20, thereby assisting in the release of seatback pad 20 from the mold. Stay 16A of headrest 16 is disposed near the front side of hanging portion 24A (see FIG. 6(A)), and stay 16A is spaced apart from hanging portion 24A to limit interference with hanging portion 24A.

[0024] The outer periphery of the seat back 14 is formed by a seat back trim 30 (see FIGS. 2A and 2B). The seat back trim 30 is provided with a bag-shaped trim cover 32 (upholstery material) as the trim main body, and the trim cover 32 is formed by sewing together a plurality of trim materials made of, for example, cloth, upholstery, or synthetic leather. The interior of the trim cover 32 is open downward, and the seat back pad 20 is inserted into the trim cover 32 from below to cover the outer periphery of the seat back pad 20. The lower end of the trim cover 32 is fixed to the lower end of the seat back frame 18, thereby causing the trim cover 32 to be stretched downward. The upper end of the rear side and the lower end of the upper part of the trim cover 32 are provided with a stitching allowance 32A and a stitching allowance 32B (see FIG. 6(A)), respectively. The stitching allowances 32A and 32B are formed by sewing the ends of the trim material together to form an overlapping structure, and protrude into the trim cover 32 and extend in the left-right direction.

[0025] A pocket 34 (see FIGS. 4(B) and 6(A)) serving as a storage section is provided on the inside of the upper rear side of the trim cover 32, and the pocket 34 is made of a fabric material with a J-shaped cross section. The lower part of the pocket 34 has a U-shaped cross section, forming a bag shape, and the lower part of the pocket 34 protrudes forward and is open upward. The upper end of the pocket 34 is sewn and fixed to a seam allowance 32A of the trim cover 32, and the lower part of the pocket 34 is sewn and fixed to a seam allowance 32B of the trim cover 32. In addition, the sewn part 34A of the lower part of the pocket 34 to the seam allowance 32B extends in the left-right direction at the center of the lower part of the pocket 34 and the seam allowance 32B in the left-right direction (see FIGS. 4(A) and 5(A) and (B)).

[0026] The hanging portion 24A of the seat back pad 20 is stored (or may be pressed in) from above within the lower portion of the pocket 34, and the lower portion of the pocket 34 is fitted between a pair of slits 28 of the seat back pad 20 (see Figures 4(A), 5(A) and 6(B)).

[0027] Next, the operation of this embodiment will be described.

[0028] In the seat back 14 of the vehicle seat 10 configured as described above, the trim cover 32 of the seat back trim 30 covers the seat back pad 20. In addition, the upper flange 24 of the seat back pad 20 is divided in the left-right direction, and a hanging portion 24A is formed in the center of the upper flange 24 in the left-right direction.

[0029] Here, a pocket 34 is provided inside the trim cover 32, and the hanging portion 24A is stored in a lower portion of the pocket 34. Therefore, when the seat back pad 20 is covered with the trim cover 32, deformation (including tilting) of the hanging portion 24A toward the inside (front side) of the seat back pad 20 due to downward extension of the trim cover 32 can be suppressed. This makes it possible to suppress, for example, the formation of a gap between the trim cover 32 and the hanging portion 24A due to the seam allowance 32B of the trim cover 32, suppress the occurrence of unevenness in the portion of the trim cover 32 facing the hanging portion 24A, and improve the appearance of the portion of the trim cover 32 facing the hanging portion 24A.

[0030] Furthermore, the lower part of pocket 34 (the part that stores hanging portion 24A) is integrated with trim cover 32 at stitching 34A. This allows the lower part of pocket 34 and hanging portion 24A to effectively follow the movement caused by downward stretching of trim cover 32, effectively suppressing deformation of hanging portion 24A into the seat back pad.

[0031] Moreover, the central portion in the left-right direction of the lower portion of pocket 34 is integrated with trim cover 32 at stitching portion 34A. This allows the lower portion of pocket 34 and hanging portion 24A to efficiently follow the movement caused by downward stretching of trim cover 32, and effectively suppresses deformation of hanging portion 24A into the seat back pad.

[0032] In this embodiment, the lower part of hanging portion 24A is stored in pocket 34. However, the entire hanging portion 24A may be stored in pocket 34.

[0033] In this embodiment, the central portion of the pocket 34 in the left-right direction is integrated with the trim cover 32 (seam allowance 32B). However, the left-right position and left-right dimension of the pocket 34 integrated with the trim cover 32 (seam allowance 32B) may be changed. [Explanation of symbols]
