Patent ID: 7578557

Claim:
A hinge mounting for a motor vehicle seat comprising: a hinge axis; an actuation part movable between a stop position and a release position; a first hinge part having an inner toothed surface centered with respect to the hinge axis; a second hinge part that, in the release position of the actuation part, is rotatable about the hinge axis relative to the first hinge part and that, in a stop position of the actuation part, is not movable relative to the first hinge part; at least one stop arm comprising a toothed region cooperating with the inner toothed surface, the stop arm being disposed for pivotal movement about a pivot axis disposed on the second hinge part and comprising a projection and having an actuation region that cooperates with the actuation part, the actuation part not biasing the toothed regions of the stop arms into engagement with the inner toothed surface when in the release position, and the first hinge part being displaceable relative to the second hinge part and the actuation part biasing the toothed region of the stop arm into engagement with the inner toothed surface in the stop position; a control part connected to the first hinge part and comprising a cam for the projection to fit against, the cam comprising several portions including a front holding region that is remote from the inner toothed surface and the toothed region of the stop arm remains out of engagement with the inner toothed surface and an engagement region that is sufficiently close to the inner toothed surface for the toothed region of the stop arm not to be prevented from coming into engagement with the inner toothed surface; and a movable baffle, wherein the engagement region is located between the front holding region and a rear holding region, that, when the projection moves from the front holding region to the rear holding region, the movable baffle associated with the engagement region bridges the interposed engagement region for preventing the projection from engaging therein, the baffle being inoperable when the projection moves from the rear holding region to the front holding region so that the projection is free to move into the engagement region.
