Abstract
An adjustable headrest is provided having a main body for supporting the head of the user, a ratchet mechanism within the main body, and a frame rotatably supported on a stay member. The ratchet mechanism includes a base plate fixed to the frame, a ratchet plate with a pawl portion, a support pin connecting the reinforcing plate and the ratchet plate, and a lock member fixed to the frame. The base plate has a receiving hole into which the support pin is inserted. A slit having a width smaller than the outside diameter of the support pin is formed in the base plate and extends backward from the receiving hole such that, when the headrest receives an impact in the backward direction, the support pin moves in the slit while widening the width of the slit under pressure. The resulting backward movement of the pin and the deformation of the slit absorbs the impact.
