Abstract
A three-wheeled competition wheelchair apparatus (10) including a wheelchair frame (11) having a beam (12) extending generally from an aft portion to a fore portion thereof. A seat assembly (15) includes a seat frame (16) carried by and supported on the wheelchair frame (11). A footrest assembly (17) includes a seat support post (20, 20') having one end movably mounted to the seat frame (16), and an opposite end, carrying footrest plates (21, 21), which is movably mounted longitudinally along the frame beam (12). The three-wheeled competition wheelchair (10) permits selective adjustment of the footrest assembly (17) between the fore and the aft position of the beam (12). Hence, the cumulative center of gravity of the wheelchair apparatus (10) and the occupant can be moved closer to effect the cumulative moment of inertia about the wheelchair pivoting vertical axis to enable more stable and shorter radius turning.
