ABSTRACT:
A vertical seat adjuster arrangement for vehicle seats includes spaced opposite hand mechanisms, each of which includes a seat support bracket. The rear portions of the brackets are supported to the vehicle by levers which are conjointly rotatable through a screwjack mechanism to raise and lower the rear portions of the brackets. The front portions of the brackets are likewise supported to the vehicle by conjointly rotatable levers. Each bracket mounts a lock plate which is movable between engaged and released positions with respect to a detent mounted to the vehicle in order to lock the front portions of the brackets against movement. Each lock plate includes a series of alternating notches and abutments, with the notches of one locking plate being offset with respect to the other to thereby obtain an increased number of adjusted positions of the brackets relative to the vehicle.
