Claim:
A headrest assembly comprising: a first frame member operatively connectable to an associated seat, wherein the first frame member comprises a slot having a first portion with a first width and a second portion with a second width that is substantially larger than the first width; a second frame member that is selectively movable with respect to the first frame member; and, a locking mechanism comprising: a first locking member having a first portion with a first width and a second portion with a second width that is substantially larger than the first width; wherein the first width of the first portion of the first locking member is less than or equal to the first width of the first portion of the slot and the second width of the second portion of the first locking member is greater than the first width of the first portion of the slot; and, a second locking member operatively attached to the first locking member for use in adjusting the first locking member between a first locked condition, where the second portion of the first locking member is received within the second portion of the slot, that prevents the second frame member from moving relative to the first frame member, and a second adjustable condition, where the first portion of the first locking member is adapted to be positioned within the second portion of the slot to allow movement of the first portion of the locking member within the first portion of the slot, that permits the second frame member to move relative to the first frame member.
