Abstract
An upwardly and downward adjustable headrest assembly for the seat backrest of a vehicle includes a fixed stay upstanding from the seat backrest, guide shoes slidable up and down along the stay and carrying a headrest body, and a locking mechanism disposed between one guide shoe and the stay for locking the guide shoe to the stay at any position therealong. The interior of the headrest provides the space needed to receive the stay as the headrest is moved up and down along the stay via the guide shoes, thereby allowing the headrest assembly to be installed on the backrest without increasing the thickness of the backrest.
