- a first housing;
a cross member rotatably supported by said first housing;
a second housing rotatably supported by said cross member and pivotable relative said first housing;
a spring axially biasing said second housing relative said first housing;
an actuation handle fixedly attached to said cross member and operable to transmit an applied force to said second housing via said cross member; and
a locking mechanism operable between a locked position and an unlocked position, said spring operable to bias said locking mechanism into said locked position, whereby said second housing is locked in one of a plurality of positions relative to said first housing, and said applied force operable to overcome the bias of said spring, whereby said second housing may be disengaged from said locked position to an unlocked position to allow said second housing to rotate relative to said first housing.

Abstract
A headrest assembly includes a first housing, a second housing rotatably supported by the first housing, and an adjustment mechanism adapted to selectively position the second housing relative to the first housing. The adjustment mechanism includes a cross member rotatably supported by the first housing and a locking mechanism operable between a locked position and an unlocked position. The locking mechanism engages the second housing in the locked position to lock the second housing in one of a plurality of positions relative to the first housing and disengages the second housing in the unlocked position to allow the second housing to rotate relative to the first housing.
