Mechanism for seating furniture with adjustment of the back, seat and legs support by means of torque sources is a complex lever mechanism, operated by one or two independent torque sources. Fig. 1 shows the mechanism with two independent torque sources. By the first torque source (51) the system of double rods for adjustment of position of the seat (56) is moved together with the back (55) and the legs support position (53). By the second torque source (52) the system of double rods for adjustment of position of the back (55) in relation to the seat (56), is started. A kinematic construction of the mechanism is made in such a way that it enables the transformation of a torque from torque sources (51) and (52) in positions of the back (55), seat (56) and legs support (53) creating thus positions for seating, relaxing or lying. |
