Abstract: An articulation mechanism comprising first and second frames mounted in a rotatable manner with respect to one another and connected together by a gear controlled by an input member (11) actuating an eccentric cam mounted in a rotatable manner in a cylindrical housing integral with the first frame. The cam is formed of two cam parts that are elastically urged towards a position of maximum eccentricity and are movable towards a position of minimum eccentricity during actuation of the input member. A load-spreading washer is mounted in a rotatable manner with play in the cylindrical housing, parallel to the eccentric cam.

Abstract: Hinge mechanism comprising a first frame and a second frame mounted to rotate relative to one another and bounding an interior space, an adjustment device adapted to allow adjustment of the angular position between the first frame and second frame, a stop member integral with the first frame and arranged within the interior space, the stop member cooperating in abutment with the second frame to limit the relative rotation of the first frame and second frame between first and second angular end-of-travel positions. The stop member protrudes from the first frame.

Abstract: hinge mechanism comprising first and second rotating frames and a control member mounted rotatably in a neck of the first frame, such control member being capable of controlling the relative rotation of the frames. A metal retaining part is held in the neck by pressing, and the control member is mounted rotatably independently of the retaining part and abuts against such retaining part.

Abstract: A mechanism for adjusting the inclination of a motor vehicle seat, said mechanism comprising: a first cheek plate and a second cheek plate, said second cheek plate being mounted to pivot on the first cheek plate; a locking device for preventing the first cheek plate from pivoting relative to the second cheek plate, said locking device comprising a first locking element coupled to the first cheek plate, and a second locking element mounted to move on the second cheek plate between an active position and an inactive position; a non-reverse device comprising a cam mounted to pivot between an active position in which said cam comes into contact with the second locking element, and an inactive position; The cam and/or the second locking element is/are provided with teeth.

Abstract: An articulation mechanism comprising a fixed cheek web, a rotational cheek web fitted with a circular tooth portion, two toothed inserts arranged at 120 degrees from each other, sliding relative to the fixed cheek web and adapted to engage with the circular tooth portion so as to lock the rotational cheek web, a cam to control the movement of the inserts, and a stop belonging to the fixed cheek web, arranged at 120 degrees from each of the inserts and acting as a support for the cam.
