摘要

The vehicle seat articulation comprises two connecting webs (24,26), one fixed to the seat and the other movable one fixed to the seat back. These two webs can rotate relative to each other around an articulation axis (X). An articulation control (32) rotates around the axis and a return spring comprises a mechanism (76) for approximate positioning of the control. The return spring also comprises a mechanism (52) for the precise positioning of the control. The cylindrical control is carried by a bearing (P1) arranged in the fixed web (24). The precise positioning mechanism comprises a pressure spring supported radially between the fixed web and a control positioning plate.
