Abstract
Abstract A recliner chair which converts from a chair configuration to a bed configuration in a single motion. The chair includes a frame, a seat, a back, an intermediate member and a linkage which provides the conversion from chair configuration to bed configuration upon forward movement of the seat relative to the frame. The linkage is comprised of two crossed links, each pivotally attached to the frame, one of which is slideably connected to the underside of the seat, the other of which is pivotally attached to the intermediate member. The links are interconnected by a bushing which is slideably attached to one link and rotatably attached to the other link.
