ABSTRACT:
An articulation for a vehicle seat, including a fixed flange, a movable flange provided with an internal circular toothing, at least one lock gear capable of cooperating with the toothing of the movable flange, this lock gear being displaceable radially by a cam, the lock gear having two opposite abutment faces which extend parallel to the direction of sliding of the lock gear from the vicinity of the toothing of this lock gear as far as a shoulder oriented in the opposite direction from this toothing. Two counter-abutment faces integral with the fixed flange are arranged facing the abutment faces and their shoulders, and one of the abutment faces penetrates into its counter-abutment face when the movable flange is subjected to a predetermined pivoting torque while the lock gear cooperates with the toothing of the fixed flange.
