ABSTRACT:
An improved three-section convertible sofa mechanism for installation in a convertible sofa. The mechanism has three sections which unfold from a sofa configuration into a bed configuration. The conversion is assisted by a motor-operated pair of bellows which assist in the lifting and positioning of the mechanism during the unfolding operation. The front edge of the convertible sofa and of the bed both deflect downwardly to eliminate the usual uncomfortable forward edge of such convertible sofas.
