Abstract
A vehicle for physically disadvantaged persons and others desiring assistance which carries a chair at a relatively high level, is supported by wheels on front and rear axles. It has a rear bumper, supported by the frame and consisting of side attaching elements connected by a bumper cross element. Pivotally connected to each bumper side element is an anti-tip wheel support leg which mounts an anti-tip wheel having an axle connected to the lower end of each leg such that the legs are gravity biased to swing in toward the bumper. The wheel-supporting legs support the anti-tip wheels at a predetermined vertical distance above the ground when the frame is traveling over level ground, and are operative to automatically swing rearwardly away from the rear wheels to cause the anti-tip wheels to engage the ground and stabilize the vehicle from further tilting, when the frame tilts upwardly a predetermined amount from front to rear.
