ABSTRACT:
A sports wheelchair also suitable for everyday use has a low, stable, planar frame and a shock-absorbing two strut suspension that places the center of gravity of the chair and user forward of the main wheel axis. The suspension supports a planar seat assembly with both lateral seat-width and longitudinal center-of-gravity adjustments. The forward end of the frame extends a significant distance beyond the forward edge of the main wheels to mount caster-type front wheels and a large, stable transfer plate.
