<p>Articulation used in motor vehicle seats including a fixed flange (1) with internal toothing (3) intended to interact either with a twin planet gear (5) whose toothings (4 and 6) mesh, on the one hand, with the toothing (3) of the fixed flange (1) and, on the other hand, with the internal toothing (7) of a moving flange (8), or directly with the internal toothing of the moving flange, an eccentric acting either on the planet gear or directly on the moving flange and a driveshaft of the eccentric equipped with at least one lug (21a), the eccentric consisting of two discs (18, 19) which can move angularly relative to each other and are joined together by an elastic element (30) housed in two arched openings (23, 24) whereas the central part of these discs (18, 19) is pierced, in the case of each of them, with at least one circular hole (18a, 19a) extended by a hollow housing (18b, 19b) intended to receive the lug (21a) of the driveshaft, characterised in that each disc is non-circular and housed in a bore (5a) of the planet gear or of the moving flange, the two discs in a position separated from each other then taking up play and making the articulation irreversible. <IMAGE></p> |
