ABSTRACT:
A one-piece guide sleeve for a vehicle seatback headrest support post enabling infinite vertical movement of the headrest. The guide sleeve provides integral locking prongs which normally apply frictional self-effort force to the support post. Conforming notches on the post are adapted to trap the prongs in a self-locking manner to prevent unintentional removal of the headrest assembly from the seatback.
