ABSTRACT:
A contact surface on a toothed segment member which controls the recline position of a seat back is abutted by one or the other of a pair of contact surfaces on a stop element to limit the recline angle of the seat back. An off-center threaded opening in the stop element is adapted to receive a bolt passed through a selected one of a plurality of adjacent openings in a bracket on the seat frame. Thus, by turning the stop element over, it is possible to provide a number of discrete stop positions equal to double the number of adjacent openings in the bracket. Cooperating curved surfaces on the bracket and stop element having their center of curvature on the axis of the seat back support shaft assist in installation and ensure that the abutting contact surfaces can fully engage each other at any angle of adjustment.
