RECLINING DEVICE FOR A VEHICLE SEAT

The present invention relates to a reclining device () for a vehicle seat of the kind comprising a first plate carrying an internal gear () and a second plate carrying an external gear () configured to cooperate with the internal gear. The reclining device includes a first and second wedge elements () for exerting a wedge effect and preventing accidental, undesired rotation of the external and internal gears relative to each other. The reclining device () further comprises a lock spring (). According to the invention the lock spring () comprises a wedge engaging element () that can be brought to abut and engage a lock spring abutment surface () of a wedge element. Thanks to this arrangement, the lock spring directly interacts with the wedge elements and directly restricts self-rotation of said wedge elements, which avoids any loss of force and function between said lock spring and said wedge elements.
