Abstract: An extendable system for sofas and armchairs uses a moveable seat and moveable head piece to travel along a curved head piece and stationary base. Frame members of the moveable seat and stationary base use a system of rails, ruler guides, notches and other wood components to facilitate the fluid movement and safe locking of the moving and stationary components.

Abstract: A furniture product includes a folding mechanism that folds into a seat frame. The folding mechanism includes a rear section, a middle section, and a front section, with the rear and middle sections being received in a cavity in the back of the seat frame when the product is in a stowed, seating position. Upon receiving a user input, a position motor deploys the folding mechanism into a sleeping position. Upon achieving the sleeping position, an inflation switch is engaged. An air pump disposed in or near the furniture product is activated in response to engagement of the inflation switch. To return the product to a stowed, seating position, a user input causes the air pump to deflate the mattress and the position motor to fold the folding mechanism into the seat frame.

Abstract: A combination jackknife bed and couch for a mobile vehicle. The jackknife bed and couch allows drivers to wake up and fold their sheets and pillow away from a seamless sleeping surface without the need to remove the sheets, blankets, pillows or other bedding materials. The sheets stay made within the folded up bed now turned into the couch. The couch may be unfolded with the sheets fully made so the driver may catch some well deserved post socializing rest without having to re-install the sheets. These features are made possible by folding the bed in and half and keeping it in the backrest of the couch. The sheets are held in place by stretchable retaining surface that may be extended over the bedding materials. When returned to the bed mode, the stretchable retaining surface must be released and potential energy in the winder may be used to retract the retaining surface.

Abstract: A convertible sofa-bed that includes a deck comprising three flat panels hinged to one another and foldably mounted on a horizontal support frame that permits their disposition either in a bed or a sofa configuration. As a sofa, the first, front panel constitutes the seat; the second, middle panel constitutes the front portion of the back; and the third, rear panel constitutes the rear portion of the back. As a bed, all three panels lay on the same horizontal plane. Conversion from the bed to the sofa configuration is achieved by folding the panels about their common hinges, which is initiated by an inverted-L mechanism pivotally mounted under the panels so as to cause the initial break of the plane between the middle an rear panels when the front panel is lifted. Once this initial break occurs, the folding of the panels is easily accomplished by pushing the front panel backwards.

Abstract: A convertible seat-bed for a van or similar vehicle. The seat-bed includes a pivoting linkage which connects the seat support, back support, and the support frame. The linkage includes an over-center front link, and a dual scissors type linkage connected between the frame and back support. The seat frame includes a manually operated latch to secure the seat-bed in the seat position.

Abstract: A seat-bed assembly is provided having a conversion linkage fixedly attached to the seat member and disposed so as to restrict movement of the seat member during conversion. The seat member is slidable along a path determined by a guide track and avoids excess vertical motion. The conversion driver is mounted to the supporting frame and connects directly to the conversion linkage. The fixed connection of the conversion linkage to the seat member occurs at a rearward extension of the seat member. The back member includes a support projection on its rear surface which rests on that rearward extension to provide increased stability to the back member in the bed position.

Abstract: A two or three section convertible sofa bed is provided for installation in vans, campers or recreational vehicles. The convertible sofa bed is adaptable to various configurations, including motor drive, yet is comparatively easy to manufacture and maintain. It has locking and stop mechanisms which combined with the arrangement of the linkage provide for a stiff, rigid structure in the seating and bedding positions. The versions with motor drive have the additional feature of providing recliner seating with variable positions. The seat frame and back frame are not directly pivotally connected to each other, thus avoiding a gap between the seat and back cushions when in the bed position.

Abstract: A base frame is provided as well as a seat support and a seat back support. Mounting structure supports the supports from the frame for movement between first seat defining positions and second bed defining positions. The seat support is horizontally disposed and projects slightly forward of a forward marginal portion of the base frame when in the seat defining position and projects further forward from the base frame when in the bed defining position. The seat back support is disposed in horizontal position immediately rearward of the seat support when in the bed defining position and is disposed in an upstanding position spaced above and projecting upwardly from rear marginal portion of the seat support when in the seat defining position.

Abstract: A mechanism for a convertible seating/sleeping article of furniture has a base which moves on a floor, a seat support member supported on the base by a scissors linkage, and a back support member which is connected to the seat support member by a first pivot. A back-lowering link is pivotally connected at second and third pivots, respectively, to one of the scissors links and to the back support member. When the mechanism is in its seating configuration, the first pivot is near a line which extends between the second and third pivots to prevent inadvertent movement of the members to their seating positions.A support leg is pivoted at the rear of the back support member, and a link swings the support leg outwardly when the back support member moves to its sleeping position.The seat-supporting scissors linkage includes a first link which is in a same vertical plane as the base, and a pair of parallel links which are pivoted to and are on opposite sides of the first link.

The intermediate leaves (12) with their relative portions of mattress (13) are folded and stored in crooked succession within a hidden zone in the base of the divan underneath the zone wherein said end leaves (12) are placed next to each other, all leaves and the mattress being extendable to form the bed.

Abstract: A convertible couch, particularly for use in vans and other recreational or leisure vehicles, includes a seat and a back hinged relative to one another, and a pair of side supports having multiple supporting surfaces arranged to engage and support the seat and back in plural positions of the seat and back. The arrangement of the supporting surfaces is such that the seat and back are firmly held in position without requiring the use of separate fasteners or linkages and the like and thus, the convertible couch is both economical to make and safe to use in moving vehicles. Additionally, the arrangement of the supporting surfaces and their cooperation with the seat and the back is such that a balance is achieved which renders the convertible couch easy to manipulate in its movements from a couch position to a bed position and vice versa.
