The rear wall 24B of 24 (not shown in FIGS. 5 to 7) covers the seat from the rear side and the seat upper side.

(Action and effect)
Next, the operation and effect of this embodiment will be described.

In the front seat 10 having the above configuration, the seat body 12 has a seat cushion 14 and a seat back 30, and a side cover 22 is attached to the side portion of the seat cushion 14. The front-rear position of the seat body 12 can be adjusted by a slide mechanism 42 having a slide rail 44 arranged below the side cover 22. Further, the vertical position of the seat body 12 can be adjusted by a lifter mechanism 52 arranged between the slide mechanism 42 and the seat cushion 14. When the lifter mechanism 52 is activated, the lower shield 58 connected to the side cover 22 and the slide rail 44 bends at the hinge portion 58C provided at the intermediate portion in the vertical direction.

Since the lower shield 58 is connected to the side cover 22 and the rail cover 50 of the slide rail 44 arranged below the side cover 22, the lower shield 58 is seated with respect to the slide rail 44. It can be prevented from being arranged so as to be offset inward in the left-right direction (see FIG. 8). As a result, it becomes easy to secure the foot space of the occupant in the rear seat (rear seat), and it becomes easy to secure the comfort of the occupant.

That is, for example, in the configuration in which the lower shield 58'is connected to the slide rail 44 and the rear rod 16B of the seat cushion 14, as in the first comparative example shown in FIG. 9, the upper side of the lower shield 58'is connected to the slide rail 44. On the other hand, the seats are arranged so as to be offset inward in the left-right direction (see the arrow OF in FIG. 9). As a result, the foot space of the occupant in the rear seat is narrowed, so that the comfort of the occupant is deteriorated, which can be avoided in the present embodiment. In FIG. 9, the same reference numerals are given to the same configurations as those in the present embodiment.

Moreover, in the present embodiment, the lower shield 58 is connected to the side cover 22 and the slide rail 44 so as to be relatively movable and non-slideable in the front-rear direction of the seat. As a result, when the lifter mechanism 52 is activated, a space for the rear seat occupant to sandwich the toes and the like is not formed between the side cover 22 and the slide rail 44 behind the lower shield 58. It is possible to prevent the feeling of being pinched by the toes and the like.

That is, for example, as in the second comparative example shown in FIGS. 10 and 11, the support portion 62 provided at the upper end portion of the lower shield 58 ”is rotatably fitted to the support shaft 64 on the seat cushion side. In the configuration in which the engaging pin 66 provided at the lower end of the lower shield 58 ”is engaged with the guide groove 68 on the slide rail side so as to be relatively movable, the seat cushion 14 is lowered from the upper most position shown in FIG. At that time, the space SP between the seat cushion 14 and the slide rail 44 behind the lower shield 58 ”expands toward the front side of the seat and contracts toward the lower side of the seat. Therefore, the occupants in the rear seats are described above. There is a possibility of feeling that the toes or the like are pinched by the space SP, but this can be avoided in the present embodiment. In FIG. 10, the same reference numerals are given to the same configurations as in the present embodiment. ing.

Further, in the present embodiment, the side cover 22 has an outer cover 24 arranged on the outer side of the seat cushion 14 in the left-right direction of the seat and an inner cover 26 arranged on the inner side of the seat cushion 14 in the left-right direction of the seat. .. The lower shield 58 is connected only to the inner cover 26 of the outer cover 24 and the inner cover 26. Since it is configured in this way, for example, when manufacturing the front seat 10, the inner cover 26 is attached to the seat cushion 14 before the outer cover 24, the lower shield 58 is connected to the inner cover 26 and the slide rail 44, and then the lower shield 58 is connected. The outer cover 24 can be attached to the seat cushion 14. At this time, since the work can be performed from the outside of the seat body 12 in the left-right direction of the seat, the work becomes easy.

Further, in the present embodiment, the lower shield 58 is slidably connected to the inner cover 26 of the side cover 22 in the vertical direction of the seat, and is connected to the rail cover 50 of the slide rail 44 in the horizontal direction of the seat. It is rotatably connected around the axis. When the lifter mechanism 52 is activated, the lower shield 58 slides in the vertical direction of the seat with respect to the side cover 22, rotates around the axis along the horizontal direction of the seat with respect to the slide rail 44, and is located in the middle portion in the vertical direction. It bends at the provided hinge portion 58C. Since it is configured in this way, the angle (range) of the bending operation of the hinge portion 58C can be set small.
