- a fixed frame including a pair of longitudinal parallel rails resting on the floor;
a pair of rigidly interconnected carriages movable along said rails in a horizontal plane between opposite extreme positions of the carriages;
a seat mounted on said carriages and displaceable therewith in said horizontal plane;
a backrest operatively connected with said seat and mounted pivotally about a first axis extending perpendicular to said rails on said frame upon displacement of said carriages between said extreme positions of the carriages which correspond respectively to a fully extended position of the divan-bed in which said seat and backrest lie in said horizontal plane and a folded position, each of the carriages being formed with;
a respective shaped lever pivotal about a respective axis parallel to said first axis and formed with a one end rotationally connected with the seat and the opposite end,a respective first rod rotatably connecting said opposite end of the shaped lever and the backrest,respective adjusting means for applying a plurality of relative angular positions between said seat and backrest while said carriages moving between said fully extended and folded positions of the divan-bed, andrespective locking means for fixing each of said angular positions.
