An inclinable seat arrangement, in particular for a sick or handicapped occupant, is described. It comprises a framework (2) and an inclinable seat (3) connected to the framework by an articulation (4) and by a positioning mechanism arranged so as to facilitate the manipulations for inclining the seat by the occupant or by another person. The axis of the articulation (4) is preferably located proximate a vertical line passing through the center of gravity (G1) of the occupant when in a position corresponding to the equilibrium position of the empty seat. An elastic mechanism, exerting a progressive return couple toward the equilibrium position, comprises elastic bearings (24) within the articulation. The elastic mechanism also preferably comprises a constant force gas thrustor (6) which includes a controlled blocking arrangement. In place of the gas thrustor there may be provided a motorized jack (51) controlled by the occupant (48). The seat arrangement may be employed in stationary or wheeled chairs for the sick or handicapped. |
