Abstract:
An articulated back sofa bed has a top pivoted back that is aligned at a downwardly forwardly aligned angle in a sitting position and, when a mattress supporting frame is deployed to a bed position an articulation mechanism displaces the seat back rearwardly, to a downwardly rearwardly aligned angle, thereby providing clearance for deployment of the mattress supporting frame clear of the bottom of the back, thereby allowing for a compact overall footprint for the sofa.

Claim (Index 1):
An sofa bed has a top pivoted back frame aligned at a downwardly forwardly aligned angle when the sofa bed is in a sitting position and a mattress mechanism is in a stowed position between arm of the sofa bed;\n a seat supporting frame portion of the mattress mechanism serves as the support surface for seat cushion when in said stowed position; a mattress mechanism is formed of a to seat supporting frame portion pivotally connected to an intermediate portion and a sleeper side frame such that the mattress mechanism can be stowed and unfolded; said mattress mechanism moves between a stowed and unfoldable position a linkage; said sofa bed has a frame formed of fixed side plates, a fixed, vertical frame and front panel with arms projecting from plates; said sofa bed has a seat back mounted to a vertical frame and actuated by an articulation mechanism that displaces said seat back about a pivot so that the bottom of back moves rearwardly; said articulation mechanism has a first bracket attached to said plates of said sofa bed; said articulation mechanism has a C-shaped link having a top arm, center portion and lower arm is pivotally attached to said bracket; said C-shaped link acts through horizontally offset thrust link, which thrust link is pivotally attached to an angled link; said angled link is formed with a lower portion, center portion and upper portion and said angled link is pivotally mounted to a second bracket; said second bracket being mounted to the back of the sofa bed whereby movement of said mattress supporting frame actuates said C-shape link to act through said mechanism to retract the back of the sofa bed to provide clearance to move said mattress supporting frame from a stowed, seating position to a mattress deployable position; said back articulation motion urged by said articulation mechanism is effected using the end of said top portion in slidable engagement in a roller slot in said seat back so that motion of said top portion causes said back to rotate on said pivot so that the lower portion of back retracts rearwardly, thereby providing clearance for mechanism to be fully deployed from a seating position to a mattress deployable position.
