<p>The invention concerns a multiple-position armchair comprising a frame (10), a seat (2), a back (1) and a leg-rest (3) mutually articulated. The articulation means (4, 6, 7, 30, 31, 32) and the control means (5) are designed to ensure co-ordinated movements of the seat, the back and the leg-rest in accordance with a predetermined continuous and unique law of displacement between a supine position (I) and an upright position (V), passing through a seated position (III). The articulation means (7, 73) of the back relative to the seat and the trajectory of the instantaneous geometrical axis (X) of articulation of the back relative to the seat are determined such that said axis (X) is permanently located at substantially constant distances respectively of the general plane of the set and the general plane of the back, so as to remain permanently substantially at the level of the user's hip joint (H).</p> |
