Abstract

Flexible wall portions inclined with respect to a front-back direction are formed on seatback side frames respectively. During normal operation of a vehicle, the flexible wall portions are held inclined by an angle θ, and the rigidity of the seatback side frames in the front-back direction is held low. Therefore, appropriate seating comfort in the vehicle seat may be ensured. In the event of a head-on collision of the vehicle, the deformation of an upper frame portion toward the rear causes the flexible wall portions to extend along the front-back direction, thereby increasing the rigidity of the seatback side frames.
