ABSTRACT:
A vertical seat adjuster for vehicle seats includes a seat support bracket. The rear portion of the bracket is supported on the vehicle by a lever which is rotatable through a screwjack mechanism to raise and lower the rear portion of the bracket. The front portion of the bracket is likewise supported on the vehicle by a rotatable lever. The front portion of the bracket mounts a pair of lock plates which are movable between engaged and released positions with respect to a detent mounted to the vehicle in order to lock the front portion of the bracket against movement. Each lock plate includes a series of alternating notches and abutments, with the notches and abutments of the locking plates being offset with respect to the other whereby the notch of one lock plate engages the detent to lock the bracket against movement while the abutment of the other engages the detent to maintain the other lock plate in released position. The alternating notches and abutment permits an increased number of adjusted positions of the bracket relative to the vehicle.
