Abstract

A head rest device for a vehicle seat includes a head rest body against which is to be rested a head of an occupant seated in the vehicle seat, a stay member supporting the head rest body and fixed to a seat back frame of a seat back of the vehicle seat, a stopper member fixed to the stay member and having a stopper portion, a rotating element rotatably supported on the stay member, and an operating member for operating the head rest body between a used position and a non-used position. The operating member is slidable relative to the rotating element and includes an operating lever manually operated to change the head rest body position and a locking element engageable with the stopper portion of the stopper member. A spring member has one end engaging the stopper member and the other end engaging the rotating element so that rotation of the rotating element is permitted by the release of the engagement between the locking element and the stopper portion of the stopper member by the slideable movement of the operating member.
