Abstract
The articulation comprises two cheeks (24, 26), one of which, which is stationary, is intended to be fixed to the seat part, and the other of which, which can move, is intended to be fixed to the backrest. The cheeks (24, 26) can rotate one with respect to the other. The articulation also includes a coupling mechanism (30) for coupling the cheeks (24, 26) together, controlled by a member (32) which can be actuated in the direction for adjusting the inclination of the backrest and in the opposite direction for temporarily folding this backrest down. The coupling mechanism (30) comprise at least one lever (34a, 34b) having two ends (36A, 36B), each of which can be secured to a cheek (24, 26) by the interaction of complementary shapes (SA, SB, TA). Cam Mechanisms (44A, 44B, 52) for manoeuvring the lever secure the latter to just one of the cheeks (24, 26) or the other, depending on the direction in which the control member (32) is actuated, by tilting the lever (34a, 34b) about a fulcrum embodied by the complementary securing shapes (SA, SB, TA).
