Abstract: A sofa is convertible to a bed. An air mattress normally stored in deflated condition in the sofa, is automatically deployed upon opening a folded framework into a bed. An electric pump inflates or deflates the mattress. A bag enclosing the bottom and sides of the mattress, is zipped onto the mattress, and has hook-and-loop fasteners securing it to strategic locations on the framework. The conversion from sofa to bed, and back to sofa, is done without removing any cushions and without moving the sofa away from anything behind it.

Abstract: A hinge assembly is mounted on a rail supported above a floor by two legs to support one end of a sofa/bed. A like hinge assembly is mounted the same way at the other end of the sofa/bed. The hinge assemblies include side rails supporting front and rear sofa frame members. Each hinge assembly combines front and rear pivot arms supporting a seat bracket, a backrest bracket and an intermediate hinge plate. A latch arm is pivoted to the seat bracket and received through a loop fastened on the intermediate hinge plate and on which a stop is provided. The latch arm is spring biased against the stop and includes a notch receivable in the stop to latch the arm. A latch dog is provided in the arm and which can be toggled between a position enabling latching of the arm against the stop, and a position enabling release of the arm from the stop.

Abstract: A multi-purpose seat for use on a recreational vehicle which allows access to a storage space provided below the multi-purpose seat. The present invention provides a multi-purpose seat adapted to be positioned into any one of a bed position, forward sofa position, backward soft position, or storage access position. The multi-purpose seat includes a seat bottom and a seat back which are hingedly attached to a housing provided in a recreational vehicle. A pivot assembly is provided on each end of the seat bottom and seat top to allow the multi-purpose seat to be positioned into any one of the aforementioned positions. Through the use of a novel pivot hinge assembly the present invention allows for access to space which has heretofore been inaccessible for use as a storage area, and moreover, allows the seat to be positioned in forward and backward facing directions.
