Abstract: An automobile vehicle seat includes two hinge mechanisms, each with a center of rotation through which a common pivoting geometrical axis passes. The hinge mechanisms are connected in rotation by a connecting bar extending, in a range between coaxial and parallel, to the pivoting geometrical axis. The connecting bar including a plurality of flattened zones offset axially relative to one another and located along the bar, the flattened zones are positioned at respective angular planes in relation to the bar axis and serving to increase bar flexibility in the flattened zone thereby reducing stress in the mechanisms.

Abstract: The automobile vehicle seat includes two hinge mechanisms (31, 32) each with a center of rotation (A, B) via which a common pivoting geometrical axis (10) passes, the hinge mechanisms being connected in rotation by a connecting bar (4) extending more or less coaxially with or parallel to the said pivoting axis. The connecting bar includes at least one flattened longitudinal zone (45, 46) in a general plane passing via the axis of the bar.
