ARTICULATION MECHANISM AND VEHICLE SEAT HAVING SUCH A MECHANISM

摘要

Articulation mechanism having first and second frames (7, 8) that are mounted in a rotatable manner with respect to one another and are connected together by a gear (10) controlled by an input member (11) that actuates an eccentric cam (29) mounted in a rotatable manner in a cylindrical housing (30a) integral with the first frame. The cam is formed from two cam parts that are elastically urged towards a position of maximum eccentricity and are movable towards a position of minimum eccentricity during the actuation of the input member. A load-spreading washer (16) is mounted in a rotatable manner with play in the cylindrical housing, parallel to the eccentric cam.
