Abstract: A sofa bed having a foldable bed frame including a main section, center section and front section which are coplanar with one another when the frame is in the bed configuration. A mattress is supported by the foldable frame and folds with it when the bed is closed or stored in the sofa frame. When the foldable bed frame is partially folded, the front section does not fully compress the mattress between the main and front sections. When the partially folded bed frame is moved to the fully folded position inside the sofa frame, a series of links causes the front section of the bed frame to move to a horizontal position and fully compress the mattress. In this fashion, the stored energy in the mattress is reduced when the frame is partially open so as to reduce the possibility of injury to the operator.

Abstract: A sofa-bed assembly comprising a rear vertical section, a lower horizontal section, a front vertical section, and an upper horizontal section pivoted to one another in succession for folding movement between a collapsed sofa condition and an extended bed contidion. A mattress folded within the assembly presses upwardly against the upper horizontal section, and a locking linkage arrangement resists the tendency of the folded mattress to swing the upper horizontal section upwardly out of a horizontal plane when the assembly is in its collapsed condition. Release of the locking linkage involves initially compressing the mattress further, thereby increasing the force required to open the bed. Additional links respond to unfolding of the rear leg, which supports the unfolded lower horizontal section for relieving some of the pressure of the mattress on the upper horizontal section, thereby reducing the force required to open the locking linkage to permit unfolding of the upper horizontal section.

Abstract: An overdeck assembly for use in a sofa bed mechanism consisting of a plurality of sections foldable between collapsed sofa positions in which sections are stacked vertically and extended bed positions in which the sections extend in substantially horizontal alignment. The overdeck assembly includes a flexible over deck member formed of a polypropylene sheet and secured to the sofa bed mechanism by a tensioning mechanism which allows the deck member to hang loosely below the sofa bed sections in the extended bed position of the mechanism and is stretched across the top of the stacked sections in the sofa position so as to provide a taut uninterrupted support surface for the sofa cushion or cushions.

Abstract: To increase the comfort of sofa-beds both in bed and seat positions, the intermediate and the deck section coverings (either textile fabric or link fabric) are anchored to fixed, transverse rigid members located at the rear (or head end) of the intermediate section and to the cavity (boxing) section. The intermediate and deck sections are independently supported so as to be stretched tight and firm in bed position and to be loose and flexible in seat position. In the seat position, both the intermediate and the deck sections are spring supported along the rear edge so as to give a soft spring support to a cushion supported from these sections. A textile flap sewn to the textile deck section and passing under a transverse deck reinforcing rod tends, in seat position, to pull the front edge of the deck section downwardly so as to flatten any bulge of the mattress so that the sofa seat cushions rest horizontal and any gaps between such cushions and the top of the front of the sofa frame are eliminated.
