ABSTRACT:
Adjustment mechanism for tilting a vehicle seat back member which is pivotally attached to a seat frame. The adjuster includes a pair of axially spaced eccentric cams which can be incrementally rotated in channels in a pair of support members carried by the seat back. The cams which are mounted on a rod carried by the seat base, are rotated by a pull out knob which carries a pair of spaced pins which are adapted to snap, under the force of a spring, into a circle of apertures in the seat frame to lock the back in a selected position of adjustment.
