<Configuration of Embodiment>
A vehicle seat 10 shown in FIG. 1 is used in a driver's seat or a passenger seat of a vehicle, and is attached to a seat cushion 11 on which an occupant such as a driver sits and a rear portion of the seat cushion 11 so as to be tiltable at a predetermined angle. The seat back 12 is provided.

  The seat back 12 is formed by covering a seat back base (not shown) constituting the seat back 12 with a cover 13. On both sides of the cover 13 on the back side of the seat back 12, fasteners 13a and 13a are provided from the lower end of the seat back 12 to a predetermined height position. After the fastener 13a is opened and the cover 13 is covered from above the seat back base, the fastener 13a is closed to form the seat back 12. Thereafter, a headrest 15 that supports the head of the occupant is assembled on the seat back 12.

  Thus, since the seat back 12 is formed by covering the cover 13, the back surface of the cover 13 is the back surface 12a of the seat back 12, the side surface of the cover 13 is the side surfaces 12b and 12b of the seat back 12, and the upper surface of the cover 13 is the seat. It is also referred to as the upper surface 12c of the back 12.

  On the back surface 12a of the seat back 12, a pocket 20 for accommodating an object is attached above the fastener 13a. The pocket 20 includes two pockets 20a and 20b arranged in the width direction of the seat back 12 (= vehicle width direction).

  In each of the pockets 20a and 20b, one piece of rectangular cloth as a sheet material is sewn within each boundary between the back surface 12a and both side surfaces 12b and 12b of the seat back 12, and the lower side of the cloth is sewn to the back surface 12a. Further, a middle portion in the width direction of the cloth is formed by sewing in the height direction as indicated by a broken line 21. That is, the broken line 21 shows a seam. Further, the lower side seam is not shown.

  However, the sewing of the cloth is performed with threads made of various materials. In addition to the cloth, the sheet material may be a natural or artificial leather sheet, a natural or synthetic rubber sheet, a resin sheet such as vinyl or plastic, or a sheet made of other materials. Furthermore, the sheet material may be a mesh shape, a material having a plurality of through holes opened, a material such as transparent or translucent, and the other side can be seen through.

  As shown in FIG. 2A, the sewing position of the cloth forming each pocket 20a, 20b is a position (hereinafter also referred to as a partitioning position) Wa, for example, 6 ( = W1): The partition position Wa is 4 (= W2). The height H of the pocket 20 is, for example, 10 cm. In this way, the pocket 20a having one width W1 is formed wider than the pocket 20b having the other width W2. However, the pockets 20a and 20b may be formed with the same width. Further, the upper ends of the pockets 20 a and 20 b are located at a position lower than the upper end of the seat back 12.

  In the present embodiment, for example, the pocket 20b with a narrow width W2 puts things such as a mobile phone or a smartphone, and the pocket 20a with a wide width W1 puts things such as a tablet terminal or a game machine larger than a smartphone or the like. It is suitable for.

The seam 21 reaches the boundary between the back surface 12a and the top surface 12c of the seat back 12 in the height direction of the seat back 12 between the pockets 20a and 20b. At the boundary portion, the back surface 12a is sewn together with a seam allowance 13b obtained by sewing the back surface 12a and the upper surface 12c together.

  The seam allowance 13b is a portion obtained by stitching the upper side portion of the back surface of the cover 13 corresponding to the back surface 12a and the rear side portion of the upper surface of the cover 13 corresponding to the upper surface 12c by a predetermined length. The seam allowance 13 b is bent to the back side of the cover 13 and is sewn together with the back side of the cover 13. Therefore, the upper end of the seam 21 is the boundary position between the back surface 12a and the top surface 12c.

  Further, both sides of the pocket 20 shown in FIG. 1 are sewn together with respective seam allowances obtained by stitching the back surface 12a of the seat back 12 and the side surfaces 12b, 12b on both sides. That is, each seam allowance between the back surface 12a and the both side surfaces 12b and 12b is folded into the cover 13 at the boundary between the back surface and the side surface of the cover 13, and is sewn together with both sides of the pocket 20 folded in the same manner. .

  Further, the lower side of the pocket 20 is sewn adjacently on fasteners 13a, 13a provided in the height direction on both sides of the back surface 12a. However, the lower side of the pocket 20 may be sewn to the back surface 12a in a state of covering a predetermined length on the fasteners 13a and 13a.
