The overall structure of the vehicle seat is roughly divided into a seat cushion 10, a seat back 20, and a headrest 30. As shown in FIG. 2, the seat cushion 10 has a configuration in which a pad 14 formed of urethane resin or the like is provided outside the cushion frame 12, and the surface of the pad 14 is covered with a skin 16. The skin 16 is made of leather, resin sheet material or cloth. Note that the basic structure including the frame, the pad, and the skin is the same for the seat back 20 or the headrest 30.

  FIG. 3 is an enlarged cross-sectional view of a part of FIG. 4 and 5 are perspective views showing the edge of the skin 16. As apparent from these drawings, a plurality of suspenders 40 are intermittently coupled to the skin 16 of the top plate side 10a of the seat cushion 10 along the edge thereof. On the other hand, a holding member 50 that can be engaged with the suspender 40 is fixed to the cushion frame 12 at a portion constituting the kerchi 10b of the seat cushion 10 (FIGS. 2 and 3).

  The suspender 40 includes a plurality of connecting members 42 and a cloth material 44. Each connecting member 42 is a resin molded product provided with a hook portion 42a at one end thereof. These connecting members 42 are coupled to one edge of the cloth material 44 by sewing or bonding in a state where the hook portion 42a is directed to the tip. The other edge of the cloth material 44 is sewn to the edge of the top plate side 10 a in the skin 16. The connecting members 42 in this state are arranged at a predetermined interval S1 along the edge of the skin 16 (FIG. 4), and when these intervals S1 are reduced to, for example, the interval S2 (FIG. 5), Gathering occurs at the edges.

  FIG. 6 is a plan view showing a part of the holding member 50. FIG. 7 is a front view from the left side of FIG. As shown in these drawings, the holding member 50 is a long resin product continuous along the cushion frame 12. And the holding member 50 is provided with the engagement recessed part 51 open | released in the front side (left side of FIG. 3), and is provided with the flange part 52 in the opposite back side. The flange portion 52 is attached to the cushion frame 12 with screws 53 (FIGS. 2 and 3). Further, on the front side of the holding member 50, a plate portion 58 extending downward from the opening edge of the engaging recess 51 is located.
