Abstract
The seat includes the structure (3) of the backrest (1) and the structure (5) of the cushion (2), the former foldable backward to provide by a slight simultaneous elevation of the cushion (2) its transformation into a bed as the folded backrest (1) and the cushion (2) are placed horizontally with their surfaces aligned. The structures (3) and (5) of the backrest and cushion are connected to each other by a swivelling shaft (10) about which they can both revolve freely, so that folding backward the structure (3) of the backrest implies pushing and raising the structure (5) of the cushion, as it is connected on its anterior part by a hinged connecting rod (7) between the structure (5) of the cushion (2) and the general fixed structure (6) of the seat.
