Abstract
Official abstract text for this publication.
A wheelchair suspension comprises a frame, at least one pivot arm, at least one front caster, at least one rear caster, a stabilizing system, and a sensor. The pivot arm is coupled to the frame. The front caster is coupled to the pivot arm. The rear caster is coupled to the frame. The stabilizing system is coupled to the frame and the pivot arm. The sensor is arranged such that tipping of the frame causes actuation of the stabilizing system to at least partially resist further movement of the frame.
First claim
Opening claim text (preview).
What is claimed: 1. A method of stabilizing a wheelchair frame comprising: actuating a stabilizing system valve upon relative upward movement of the wheelchair frame with respect to a rear caster; wherein actuation of the stabilizing system valve causes a fluid spring to at least partially resist tipping to the frame by at least partially resisting movement of a front caster relative to the frame. 2. The method of claim 1 wherein actuating the stabilizing system valve at least partially resists upward and downward movement of the front caster relative to the frame. 3. The method of claim 1 further comprising allowing downward movement of the front caster with respect to the frame when the stabilizing system valve is actuated. 4. The method of claim 1 wherein the front caster is a first front caster and actuation of the stabilizing system valve simultaneously resists movement of the first front caster and a second front caster relative to the frame.
