ABSTRACT:
In general, sofa beds are complicated structures and are commonly difficult to operate. A relatively simple sofa bed includes a pair of generally U-shaped bases for resting on the floor, each base being defined by vertical front and rear arms, a rearwardly inclined cross bar extending between the front and rear arms, a track mounted on the crossbar, a rectangular seat frame connected to the base by a pair of link arms, one of which is pivotally connected to the front arm of the base, and the other of which is connected to the track, so that the front end of the seat frame can be lifted and rotated forwardly from the inclined sofa position to the horizontal bed position, and the back frame pivotally connected by one link arm to the rear arm of the base and by another, generally C-shaped link arm to the rear end of the seat frame, whereby the back frame is normally supported in a steeply inclined sofa position, but during movement of the seat from the sofa position to the bed position corresponding movement of the back frame occurs from the inclined, sofa position to the horizontal bed position.
