ABSTRACT:
A convertible seat-bed is provided in which seat and back cushions are attached to frames which are supported from a linkage for movement between a seating condition in which the back cushion extends upwardly and rearwardly from the rear edge of the seat cushion and a bed condition in which body-engaging surfaces of the cushions are in a common horizontal plane. The linkage includes a front swing arm pivotally connected at its upper end to a back frame, a rear swing arm connected at its upper end and to the back frame through a short link and a link between the swing arms extending forwardly to the lower end of another link which is pivotally connected at its upper end to a seat frame and which is connected through a further link to the front swing are. The linkage operates to keep the rear edge of the seat cushion in close proximity to an adjacent edge of the back cushion in both conditions and is located below and behind the seat and back cushions. The front of the seat cushion may be lifted for access to storage space and also to facilitate operation between the seating and bed conditions.
