ABSTRACT:
A mechanism for supporting and permitting selected adjustment of the position of a headrest relative to the back of a chair comprises a body, a first pivotable connection, a second pivotable connection and a selectively releasable locking mechanism. The first pivotable connection is near the first end of the body, adapted to connect to the chair and to allow pivoting of the body relative to the chair. The second pivotable connection is near the second end of the body, adapted to connect to the headrest and to allow pivoting of the headrest relative to the body. The selectively releasable locking mechanism is configured to retain the body in selected angular positions relative to the chair and relative to the headrest by clamping together interleaved plate members in frictional contact and to allow for one-handed actuation.
