ABSTRACT:
A vehicle seat has a seat cushion frame supported on a seat frame by height adjustment mechanisms located at the front and rear of the seat. The rear height adjustment mechanism comprises a hinge plate pivoted at opposite ends to the seat frame and to the rear edge of the seat cushion frame, a rack pivoted to the seat frame and formed with vertically spaced slots, and a locking pin carried by the hinge plate and engageable in any selected one of the slots. The rack is movable by a handle out of engagement with the locking pin to release the seat cushion frame for upward movement under the force of a biasing spring or for down movement under the load of the seat occupant. Release of the handle engages the locking pin with the slot of the rack lying nearest opposite it to lock the adjustment mechanism.
