ABSTRACT:
An automobile seat includes a seat cushion frame, a side frame, and a seat back frame mounted on the side frame to be rotatable within a limited angle. An elastic member and a guide portion having an elastic member holding portion are mounted on the side frame and the seat back frame. The seat back frame is normally fixed to the side frame with the elastic member held in the holding portion, but when a load greater than a predetermined value is inputted from behind, a lower portion of the seat back frame is pushed rearward by a lumbar part of a seat occupant to thereby deform the elastic member, which in turn leaves the holding portion and moves rearward along the guide portion, thus causing the seat back frame to rotate with respect to the side frame and causing the headrest to move forward.
