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.
1. A method of stabilizing a wheelchair frame comprising: creating a magnetic field between a magnet and a locking member upon relative upward movement of the wheelchair frame with respect to a rear caster;wherein creating the magnetic field causes the locking member 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 creating the magnetic field at least partially resists upward and downward movement of the front caster relative to the frame. ...
