ABSTRACT:
A convertible sofa bed particularly adapted for use in recreational vehicles. The bed includes a frame, a seat portion, and a back portion pivotally connected to the seat portion for movement between a horizontal and an upright position. A pair of pivot assemblies at opposite sides of the seat frame each includes front and rear pivot arms, one attached to the seat portion and the other to the back portion. A connecting link attached to the arms constrains them against movement independently of one another. The arms and connecting link are arranged and oriented to pivot one way to project the seat portion forwardly and move the back portion to a horizontal position to form a bed. Pivoting them the opposite way retracts the seat portion and moves the back portion to an upright position, converting the structure from a bed to a sofa.
