ABSTRACT:
An angle adjustment device is disclosed in which the angle of inclination of a headrest or thigh support can be adjusted by rotating a movable body itself forming a part of the headrest or thigh support. When the movable body is rotated, sectors fixed to the movable body are rotated together with the movable body and are engaged with a stopper rod secured to a bracket. Thus, the sectors are locked in a desired position, that is, the angle of the movable body is adjusted. When the movable body is rotated beyond a predetermined angle of rotation, the sectors are disengaged out of the stopper rod and the movable body is rotated in an opposite direction so as to return to its initial position.
