Abstract:
A vehicle seat having first and second frames mounted so as to pivot relative to one another about an axis of rotation by means of at least one pivot mechanism, designed to allow a user to choose and lock a relative angular position of the first and second frames, this pivot mechanism comprising first and second rigid side plates fixed respectively to the first and second frames of the seat, at least the first side plate having a relief arrangement disposed in an annular zone substantially centred on the axis of rotation which co-operates, by meshing, with a complementary relief arrangement of the first frame in order to immobilize this first side plate and this first frame relative to one another in rotation, wherein the first side plate is integral with a single threaded fixing member which extends substantially along the axis of rotation and which co-operates with a complementary threaded fixing member by a screwing action, applying a flange against the first frame in a direction of the first side plate, at least on an annular bearing zone adjacent to the relief arrangement of the first side plate and the complementary relief arrangement of the first frame.
