Abstract
A seat back comprises a support bracket in which a stay of a head rest is inserted, a guide bracket for supporting a rear surface of a vertically intermediate portion of the support bracket on the seat back frame, a head rest tilt mechanism, and a pressure receiving member which moves rearward when pushed by the body of an occupant. The head rest tilt mechanism includes slotted brackets each having a guide hole and slide members which individually movably engage the respective guide holes of the slotted brackets along the longitudinal direction thereof. The head rest tilt mechanism drives the sub-frame so that the head rest body tilts forward while moving upward as the slide members are moved upward along the guide holes when the pressure receiving member is moved rearward.
