Abstract
A head rest lock enables the adjusting of the elevational position of a head rest of a vehicle seat having sleeves that serve as vertical guides for support posts having lock notches therein, the notches providing a plurality of vertical height adjustment positions. The sleeves include a lock latch for manually activating the adjustable height mechanism and ribs which prevent inadvertent rotation of said sleeve. The head rest lock is mountable to a bracket or directly to a seat back frame.
