ABSTRACT:
An adjustable seat framework includes two frames articulated to one another, termed respectively first and second frames, joined by pivots, the first frame including at least one guide slot and the second frame including at least one associated operating slot, the associated guide and operating slots emerging in neighboring parallel planes and extending longitudinally in non-parallel directions, the adjustable framework further including, for each set of associated guide and operating slots, a roller which penetrates into said slots. An operating mechanism is provided for shifting the roller along the guide slot, which causes the rotation of the second frame about the pivots.
