Hypocycloidal train mechanism for a vehicle seat, including a brake with anti-reversing properties and differential torque

Abstract

Abstract Mechanism with hypocycloid gear train, comprising a non-reversible brake with differential torque, for vehicle seats, characterised in that, in front of the ball bearing (10) lodged between, on the one hand, the double satellite (3) and, on the other hand, the control cam (9), there is placed, on the face turned towards the movable flange (4) of this ball bearing (10), an annular spring (15) with semi-circular cross-section one of whose curved ends (15a) is hooked into a receptacle (16) of the cam (9) created on one of the centring axes of the mechanism with hypocycloid gear train whereas the other end (15) is free so that, during rotation of the mechanism in the direction for lowering or raising the back of the seat, friction of the outer end (15b) of the spring (15) is created between the internal part of the satellite (3) thus ensuring continuous rotation without jolts giving rise to a constant rotational speed of the movable flange (4). <IMAGE>
