The adjuster comprises fixed and moving flanges (10,20) fixed to the seat base and back. A guide is associated with one of the flanges to define their axis of rotation. A regulating mechanism with a toothed ring (41) is carried by one of the flanges. One or more toothed wedges (42) engage with the ring and are able to move relative to the other flange, on which they are mounted, between engaged and disengaged positions. The adjuster has an actuator for moving the regulator between its two positions. The adjuster has at least one cam (51) on a lever (511) which is able to move transversely and rotate relative to the fixed flange (10). At least one counter-cam (52) is located on the toothed wedge (42). The levers are operated by a transmission mechanism with a moving member (532) which acts on the lever in a position offset from its instantaneous centre of rotation. |
