The chairs has frames connected with each other and articulated by using cut bearings (9, 10). Movement of a backrest (1) of one of the frames, a base (2) and a leg support (3) is obtained by the articulated connection of the frames, in points (11-14) for obtaining an articulated parallelogram. The movement of the parallelogram is obtained by sliding elements (15) into respective articulative elements (16) placed below armrests (4). Simultaneous variation of angulation of the backrest, base and the support is obtained by cut bearings (12a-14a) in the points. |
