Abstract
An anti-tip suspension for a wheelchair having rear casters is defined. The suspension includes a rocker arm support, a rocker arm and a spring. The rocker arm is pivotally attached to the rocker arm support so that it is rotatable with respect to the rocker arm support. The spring engages the rocker arm and rocker arm support, biasing them away from one another. The rocker arm includes a rotation limiter that limits the rotation of the rocker arm with respect to the rocker arm support in one direction.
