<p>The device has an unlocking lever (11) driving a pivoting rod (20) by rotational movement with respect to a flange (4), where the rod freely moves a shift finger (25). The finger describes a circular groove (26) provided in the flange when a rear support plate (5) is pivoted around an axle (6) to be folded on a base (2). An extension (27) is pivoted with the lever, such that the lever acts on a disengageable unit (7) correcting a backrest (3) in maximal position forwards around an axle (13). The lever is set under the finger to immobilize the finger and maintain the plate in folded position.</p> |
