ABSTRACT:
A sofa-bed having an articulated folding structure comprises a fixed carrying framework (2) to which a main movable frame (3) is engaged through a pantograph linkage (4), which main frame is movable in a vertical direction. Consecutively and rotatably connected to the main movable frame (3) are first and second auxiliary movable frames (17, 18). An interconnecting lever (20) operating between the main movable frame (3) and the second auxiliary movable frame (18) interconnects the rotational movements of the movable frames (17, 18). A synchronization lever (21) operatively connects the pantograph linkage (4) to the auxiliary movable frames (17, 18) for the purpose of timing the upward and downward displacement of the main movable frame (3) with the rotations of the auxiliary movable frames (17, 18).
