Abstract
Abstract A convertible sofa bed and cover particularly adapted for use in recreational vehicles. The bed includes a frame, a seat portion including a seat cushion, a back portion including a back cushion and adapted to be moved between a horizontal bed position and an upright sofa position, and a pivot apparatus for pivoting the back portion between the bed position, in which the seat and back cushions abut, and the sofa position, in which the lower terminus of the back cushion is located above and forwardly of the rearward terminus of the seat cushion. The bed includes a flexible cover attached to the upper or support surfaces of the seat and back cushions to cover the juncture or crevice between them in their bed position. The cover is attached to the seat cushion forwardly of the juncture and extends rearwardly to form a flap which covers the lower face of the back cushion when the back cushion is in its sofa position.
