Abstract
An adjustable headrest includes a rotatable member positioned between a stationary member and a movable member to which a padded head support is attached. The member has opposed staggered arcuate surfaces extending on opposite sides of a pivot point with one of the surfaces including teeth which selectively engage teeth on the movable member, while the remaining arcuate surface of the member engages a stationary portion of the headrest. A spring holds the teeth in removable engagement with each other and an articulated release arm selectively disengage the teeth to retract the head support.
