A tilt adjustment mechanism for a vehicle seat that is used to adjust the
angular orientation of a seat back relative to a seat base. The tilt
adjustment mechanism has a driver that has two protrusions that are
rotated with the driver by a drive shaft. Initially the driver rotates
independently of a cam assembly until a driving protrusion of the cam
assembly is engaged. The movement of the driver continues to release a
locking wedge that releases the seat back for adjustment.
