Abstract
A wheelchair has a suspension system that includes a front caster housing mounted forward of a wheelchair frame by means of a front linkage. The front caster housing supports a front caster. A drive wheel pivot arm, on which a mid-wheel-drive drive wheel is mounted, is itself mounted for pivoting with respect to the frame. A flexible tension member is connected to both the drive wheel pivot arm and the front linkage. The mounting of the flexible tension member is configured so that rotation of the drive wheel pivot arm in a downward direction applies tension to the flexible tension member, causing the upper link to rotate upward, and thereby lifting the caster housing and the front caster.
