This device comprises elements for fixing it to slides (6) which are longitudinally movable on fixed slides (10), other elements allowing the mounting of a seat (4) carrying a cushion (3) and a backrest (2), and, on each side of the seat structure, a cam (5) interposed between the slide (6) and the seat (4). There are provided in the cam (5) bearing tracks (7, 8) for the cam (5) on the slide (6) for the adjustment of the cam (5) in height.
