  • Patent number: 4996730
    Abstract: A sofa bed recliner with a back frame that has no rearward movement when converting from a sitting position to a horizontal position, is provided with simple support legs, which facilitate the ease of converting and reverting the sofa bed recliner and providing proper support against overbalancing. The legs drop from beneath the seat frame when it is pulled forward and retract over the base, beneath the seat frame, when reverting. The legs have a stop so that they cannot get entangled with the base when the seat frame us lifted. A tension spring biases the back frame to facilitate movement.
