(Function and effect)
Next, the operation and effect of this embodiment will be described.
In the vehicle seat 10 configured as described above, the skin 36 and the hinge cover 38 are provided side by side in the front-rear direction of the seat on the side surface 20A on the inner side in the vehicle width direction of the seat cushion 20, and the trim cover 14 is sewn on the skin 36. Is attached by. On the hinge cover 38 side of the trim cover 14, a resin component attachment portion 14A that is not sewn with respect to the skin 36 is provided, and a rubber band 16 is attached to the resin component attachment portion 14A. . The rubber band 16 is fixed to each of the hinge cover 38 and the resin component mounting portion 14A and elastically connects the two. Thereby, the trim cover 14 attached to the skin 36 is attached to the hinge cover 38 via the rubber band 16.

  Here, the distances between the attachment positions of the trim cover 14 with respect to the skin 36 and the hinge cover 38 are relative to each other depending on the attachment error between the skin 36 and the hinge cover 38 in the seat cushion 20, the attachment error of the trim cover 14 with respect to the skin 36, and the like. Will be uneven (displacement). In this respect, in the present embodiment, as described above, the trim cover 14 attached to the outer skin 36 is attached to the hinge cover 38 via the rubber band 16. Relative variation can be absorbed. Accordingly, it is possible to avoid the difficulty in attaching the trim cover 14 to the hinge cover 38 due to the relative variation as described above, so that the manufacturing efficiency can be improved.

  The above effect will be described in detail using a comparative example 50 shown in FIGS. In the comparative example 50, the trim cover 14 is directly fixed to the hinge cover 38 by the clip 18 penetrating the circular hole 52 formed in the trim cover 14 and the locking hole 42 of the hinge cover 38. The rubber band 16 (elastic member) is omitted. The other configuration is the same as that of the present embodiment.

For this reason, even when the trim cover 14 is misaligned with respect to the hinge cover 38 in either the front or rear of the seat, the misalignment can be absorbed by the expansion and contraction of the rubber band 16.

  Further, in the present embodiment, the rubber band 16 is attached to the hinge cover 38 by the clip 18 penetrating the rubber band 16 and the hinge cover 38. For this reason, the rubber band 16 and the hinge cover 38 may be formed with holes (the insertion hole 40 and the locking hole 42) for allowing the clip 18 to pass through, and the rubber band 16 is attached to the hinge cover 38 with a simple configuration. Can do.

  In the present embodiment, the clip 18 has a head portion 18 </ b> A located between the trim cover 14 and the rubber band 16. Therefore, even before the rubber band 16 is fixed to the hinge cover 38 by the clip 18, the head 18 </ b> A of the clip 18 interferes with the trim cover 14 and the rubber band 16, so that the clip 18 from the rubber band 16 is Inadvertent dropout can be prevented.

  In the first embodiment, the rubber band 16 is used as the elastic member. However, the present invention is not limited to this, and any elastic member may be used as long as it elastically expands and contracts. For example, a highly stretchable cloth material may be used as the elastic member, or a member formed to be stretchable by a resin material or a metal material may be used as the elastic member.

  In the first embodiment, the rubber band 16 is fixed to the hinge cover 38 by the clip 18. However, the present invention is not limited to this, and the rubber band 16 may be configured as a modified example 60 shown in FIG. .

  In this modified example 60, in the hinge cover 38, a protrusion 38A that protrudes outward in the seat width direction (herein, in the vehicle width direction) is integrally formed at a portion facing the rubber band 16 instead of the locking hole 42. Is provided. This protrusion 38A is formed in a columnar shape, for example, and is inserted into the insertion hole 40 of the rubber band 16 from the inner side in the sheet width direction. A barb is formed at the tip of the protrusion 38 </ b> A that penetrates the insertion hole 40, and the barb is hooked to the outer surface of the rubber band 16 in the sheet width direction. Thereby, the rubber band 16 is fixed to the hinge cover 38. In this modified example 60, since the clip 18 is not used, the number of parts can be reduced.
