| 摘要 |
The invention mainly concerns a releasable hinge assembly for a motor vehicle seat comprising: - first and second flanges disposed coaxially about the rotational axis of said releasable assembly and secured respectively to the seat and to the seat back, or vice versa, - a release disc linked in rotation to the second flange, and - a release member that can be actuated in rotation in order to drive said release disc in axial translation from a locked position in which the first and second flanges are constrained to rotate with each other, to a released position in which the first and second flanges pivot freely relative to each other, and that is essentially characterised in that it comprises a reinforcing ring (29) in annular contact with the release disc (25) and the second flange (27), and comprising means (292, 253a) for the axial sliding of said release disc (25) relative to said second flange (27) when the release disc (25) shifts from the locked position to the released position and vice versa. |
