ABSTRACT:
A vehicle seat is provided with a pair of left and right seatback side frames comprising a seatback frame. The seatback frame is connected to the rear end of a seat portion frame via a reclining mechanism. The vehicle seat is further provided with a torsion bar that is an elastic body between the reclining mechanism and the seatback frame. When the seatback frame displaces and falls forward relative to the seat portion frame, the torsion bar deforms and resists the displacement of the seatback frame. The torsion bar is arranged at the upper region of the seat occupant's pelvis.
