ABSTRACT:
The seat made up of a seat (10) with a moving framework (11) for a cushion (12), of a backrest (20) with a moving framework (21) for a cushion (22), of an underframe (30) intended to make the seat rest on a floor, of an articulation (40), as well as of linkage rods (50) for automatically controlling the relative displacements of these cushions (12, 22) is noteworthy in that these linkage rods (50) comprise, on the one hand, a connecting rod (51) connecting, in articulated manner, one of the extremities of the framework (11) to the underframe (30) and, on the other hand, a connecting rod assembly (52) connecting, in articulated manner, the other of the extremities of the framework (11) to the framework (21) so that, in a first mode, when the backrest (20) passes from its normal position to one of its extreme positions, the seat part (10) retains, at least locally, a practically stationary position so that its cushion (21) faces the cushion (22) and that, in a second mode, when the backrest (20) passes from its normal position to the other of its extreme positions the seat part (10) changes position so that its cushion (11) comes practically into alignment with the cushion (21), and vice versa.
