Abstract (en)
A chair for medical use comprising a base (1) supporting a seat (2) to which seat (2) a backrest and a legrest (4) are hinged. Movement and adjusting means (5) of the seat (2) are hinged between the base (1) and the seat (2) and comprise a first four-bar linkage (6, A-B-C-D) and a second four-bar linkage (7, C-D-E-F) of the same length and constrained to each other at a common smaller side (C-D). The first bar linkage (6) is connected at a remaining smaller side (A-B) to the base (1) and can move by an angle alpha, while the second bar linkage (7) is constrained by a remaining smaller side (E-F) to an end of the seat (2). Two bidirectional kinematic connectors (8) are positioned between the first and the second bar linkages (6 and 7) and are each solid to one large side (A-D, F-C) of the bar linkages (6, 7) so as to determine at an angle alpha of the first bar linkage (6) an angle 2 alpha between facing large sides (B-C, E-D) of the two bar linkages (6, 7). <IMAGE>
