Abstract
A two frame sofa bed recliner has a seat frame and back frame. The frames are elevated from the floor on supports. The frame ends are linked, overlapped, interengaging the seat frame with the back frame, enabling a simple conversion reconversion process from sofa bed to recliner. In recliner position the back frame tilts rearward on its end. The back frame is interlocked with the seat frame locked by a detent, retaining means and a second detent in a guide. Conversion and reconversion are effected by rotating the interlocked unit on to the back frame supports, disengaging the seat frame and back frame, then lowering the seat frame to the floor on the supports and interlocking the frames. For reconversion the process is reversed. A removable arm rest is attachable.
