  • Patent number: 6161231
    Abstract: A sleeper sofa incorporating an air mattress including a telescoping mattress frame for supporting a mattress support subassembly consisting of hinge panels. The hinges used to connect the panels limit the angular range of motion of adjacent panels to plus or minus 90.degree. from a coplanar arrangement. The "panel" that defines the seating surface on which seat cushions rest when the sofa is in the seating position may be supported in the seating position by a pair of side rails that lack significant structure in the seating plane. This "panel" may also include a set of sinuous springs clad in padding similar to the seat-cushion support surface of a conventional non-sleeper sofa. The air mattress used in the sleeper sofa can be a multi-chamber design in which the outer edges of the mattress are inflated to a higher pressure to prevent the user from rolling off the edge of the mattress.

    Abstract: A convertible sofa bed particularly adapted for use in recreational vehicles. The bed includes a frame, a seat portion, and a back portion pivotally connected to the seat portion for movement between a horizontal and an upright position. A pair of pivot assemblies at opposite sides of the seat frame each includes front and rear pivot arms, one attached to the seat portion and the other to the back portion. A connecting link attached to the arms constrains them against movement independently of one another. The arms and connecting link are arranged and oriented to pivot one way to project the seat portion forwardly and move the back portion to a horizontal position to form a bed. Pivoting them the opposite way retracts the seat portion and moves the back portion to an upright position, converting the structure from a bed to a sofa.
