Further, when a load is input to the vehicle from the front or the rear, the main body support bracket 21 and / or the follower support bracket 22 are deformed and absorb impact energy at a position away from the occupant. Therefore, the impact energy absorption efficiency is improved.
- the deformation of the brackets 21 and 22 is not limited to deformation in the vehicle front-rear direction, and includes deformation in the vehicle width direction.
- the body portion support bracket 21 that supports the body portion 17 or the follower portion 19 of the reclining mechanism portion 11 and the bent portions 23 and 25 of the follower portion support bracket 22 are input to the seat frame 6 from the front or rear of the vehicle.
- the impact energy can be absorbed by being deformed in the vehicle longitudinal direction by a load. Therefore, the brackets 21 and 22 do not deform so as to protrude toward the occupant side, so that a space between the occupant and the seat frame 6 can be secured even when an impact load is input.
- the bent portions 23 and 25 of the brackets 21 and 22 are deformed by the load input to the seat frame 6 to absorb the impact energy, so that the energy can be absorbed with a simple structure. it can.
- the notched portion 26 is provided in the bent portion 25 of the follower portion supporting bracket 22, the notched portion 26 promotes deformation of the bent portion 25.
- the bent portions 23 and 25 are attached to the attachment points of the brackets 21 and 22 and the seat cushion frame 6A and the attachment points of the brackets 21 and 22 to the main body portion 17 and the driven portion 19. Since it was provided in between, the size of the bracket can be reduced.
- the follower support bracket 22 has a flat plate shape and is fixed to the side surface of the seat cushion frame with the plate thickness direction as the mounting direction. Therefore, the folding seat 2 for one person as shown in FIG. Even in the case of a sheet having a structure in which the folding seat 3 for two persons is connected, it can be disposed between adjacent sheets, and the space between the sheets 2 and 3 need not be widened unnecessarily.
- FIG. 7 is a cross-sectional view showing the vicinity of the main body support bracket according to the second embodiment, and corresponds to FIG. 3 in the first embodiment.
- FIG. 8 is a side view showing the vicinity of the follower supporting bracket according to the second embodiment, and corresponds to FIG. 4 in the first embodiment.
