A articulation mechanism for a motor vehicle seat is disclosed. The mechanism may include a first end-plate, a second end-plate mounted so as to pivot relative to the first end-plate about a main axis of rotation, locking elements comprising a first locking element and a second locking element that can be moved between an active position and an inactive position, a cam that can be moved between a locked position in which it holds the locking elements in the active position and an unlocked position in which it holds the second locking element in the inactive position, guide elements capable of guiding in rotation each of the locking elements, and a bearing surface preventing the first locking element, but not the second locking element, from being in the active position in a range of angular tilting positions.
