<p>The base has a trunk support part and a legs support part articulated with respect to a non-deformable rigid frame (20) and inclining in order to pass from a laid down position to a sitting position. A fixed intermediate part (40) is firmly connected to the frame, which is immovable, where the intermediate part comprises articulation axles (43, 44) for the trunk support part and/or the legs support part, so that the concerned articulated support part inclines completely independent of the frame. Each axle is located at corresponding ends of the intermediate part.</p> |
