Abstract: A convertible sofa-bed unit for a vehicle in which a back section is mounted on a seat section and is moveable from an upright position near the rear of the seat section to a horizontal position in front of the seat section, and a device is provided for preventing the movement of said back toward the forward edge of the seat in response to a sudden forward lurching of the back section. The strap is preferably connected at one end to the rear of the back section near the upper edge thereof and is wound on a ratchet controlled reel preferably disposed beneath the rear edge of the seat section, and an inertia responsive device prevents unreeling of the strap when the sudden forward lurching of the back section occurs momentarily.

Abstract: A convertible sofa-bed unit in which the back is moved from a substantially vertical position along the rear of the seat section to a horizontal position along the forward edge of the seat, and substantially on a plane therewith. The back is held in the two positions by a mechanism at each end, each consisting of two arms connected to the ends of the seat section and the back section which cause the back section to rotate to place the surface facing forward in the sofa position to the upwardly facing arrangement in the bed position. A support member is provided at each end of the seat section near the forward edge thereof for engagement by one arm at each end, capable of fully supporting the back in the bed position so that no legs are required for use of the unit as a double bed.
