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.
