A hinge mechanism has a fixed cheek-plate and a pivoting cheek-plate that can be prevented from moving relative to the fixed cheek-plate by toothed slugs under the control of a cam. Between the two cheek-plates, there is disposed a circular guide having radial gaps which receive the slugs and which hold them in a retracted position once they have become disengaged from the radial gaps. The circular guide can be prevented from moving relative to the pivoting cheek-plate by actuating a control plate which disengages the slugs from the gaps. The pivoting cheek-plate can thus turn freely in one direction and then in the opposite direction before locking again in its initial angular position once the radial gaps of the circular guide come back into register with the slugs.

Hinge mechanism for a vehicle seat, and a vehicle seat fitted with such

This concerns a hinge mechanism comprising a fixed end plate, a movable end plate lockable by two wedges controlled by a sliding pushrod, itself activated by pivoting of a control plate in a first or second direction in order to free the movable end plate. A circular guide comprises radial breaks receiving the wedges, and holding the wedges in a withdrawn position when they disengage from the radial breaks under the pivoting effect of the control plate in the second direction, which fixes in addition the circular guide to the movable end plate. The movable end plate can thus turn freely before relocking in its initial angular position when the radial breaks of the circular guide return opposite the wedges.
