ABSTRACT:
A folding bed frame for sofa-beds in which a plurality of frame sections, including a foot section, knee section, body section and head section are pivoted in end-to-end relation so as to be foldable between an extended bed-forming position and a retracted sofa seat-forming position; wherein front and rear support and guiding link assemblies coact to control movements of the body section and head section during movements to the extended bed-forming position and to the retracted sofa seat-forming position. The link assemblies are supported by a pivoted front anchor link and a rear rocker lever anchor link, which are interconnected by a control link. The mounting arrangement operates to move the frame sections, during folding and unfolding operations, through a path having greater floor clearance, and thus permits a number of advantageous changes such as increased bed length and greater depth of the space for the folded mattress, while still utilizing the restricted dimensions dictated by the furniture framing structure. By a further modification in which the head section is constructed as two sections instead of a single section it is possible to obtain a still greater bed length. The two sections of the head section are capable, in the folded position of the mechanism, of occupying a limited angular orientation permitting them to occupy the confined back area of the sofa frame structure.
