ABSTRACT:
A wheelchair and rolling suspension system are supported by a pair of inclined, nested circular hoops. The hoops may be manually driven by lever arms accessable to the chair occupant. Moreover, the drive system permits the chair to negotiate straight lines, gradual and sharp curves, as well as to rotate about a vertical axis. The wheelchair is a two-wheel system having self-righting characteristics and is collapsible for storage and transportation. A seat assembly is articulatable between a vertically upright position and a fully reclined position. In addition, the wheelchair can function as a rocking chair.
