Seat transformed into bed and opened automatically - has rectangular frame with bars articulated on each other and joined to base and having lever forming leg of bed and holding frame folded

摘要

The base of the seat (1,2,4,6) supports a rectangular frame formed by four bars (8-11), articulated to each other by their ends. The first bar (8) is articulated on the base's vertical bar (6). A headrest (27) is articulated on a return (39) articulated on the end of the fourth bar (11). A stop (51) on the fourth bar limits the forward pivoting of the headrest and makes the back and frame rigid. A right-angled lever (14), articulated on the fourth rod, forms a leg of the bed and a support between the second and fourth bars when the frame is folded. USE/ADVANTAGE - The seat opens to form a bed and is opened automatically.
