ABSTRACT:
A reclining chair that meets requirements of chair design promoting occupant comfort: The chair, suitable for use as a bed, provides a means whereby when the seat moves forwardly, the backrest reclines and vice versa, thereby controlling the position of the center of gravity in all backrest positions, and thereby also maintaining approximately the same seat height in all backrest positions. The chair provides a means for adjustably positioning ground engaging components such as wheel assemblies, rocker arms, and other ground engaging devices to alter seat angle. The rocking function also has therapeutic advantages. The use of wheel assemblies, which may be motorized, permits use as a wheelchair. The chair supports the occupant via a plurality of closely spaced springably supported transverse slats. Such support is designed to provide approximately constant average spring deflection in the backrest, seat, and legrest segments at an intermediate backrest angle. The frame is foldable and of uncluttered and functional appearance. The manner and process of making the chair is described in detail including proportions and techniques as necessary in computer program CHAIRFIT. The program discloses a process of manufacture for customizing and determines other data related to chair construction and design.
