Abstract
A wheelchair suspension is provided. The wheelchair suspension includes a frame, a pivot arm, a front caster, a drive assembly, and a rear caster. The pivot arm is pivotally coupled to the frame. The front caster is coupled to the pivot arm. Movement of the drive assembly in a first direction causes the pivot arm to substantially remain in a first position. Movement of the drive assembly in a second direction urges the pivot arm away from the first position.
