JOINT MECHANISM

Abstract

Articulation mechanism (10) for a seat comprising a movable flange (20) including a platform (21) and an internal toothed ring (22), the internal toothed ring (22) being centered on a first axis (A1), and a fixed flange (30) including an external toothed ring (32) centered on a second axis (A2) parallel to the first axis (A1) and meshing with the internal toothed ring (22) of the movable flange (20), the external toothed ring (32) including, on an inner side (33), a bearing face (36b) which bears axially on the platform (21), characterized in that the external toothed ring (32) includes, on the inner side (33), a deformation extending at least partially over its periphery such that a peripheral edge (38) of the external toothed ring (32) is at least partially away from the platform (21).
