ABSTRACT:
A power driven wheel chair is described which includes a rear wheel support frame and at least two ground engaging rear wheels mounted in spaced relation to opposed sides of the rear wheel support frame. A front wheel support frame is pivotally secured to the rear wheel support frame for pivotal movement about a substantially horizontal axis. At least two ground engaging front wheels are mounted in spaced relation to opposed sides of the front wheel support frame. A drive motor provides motive force to at least one wheel of one of the pairs of at least two ground engaging wheels. A chair is mounted on one of the rear wheel support frame and the front wheel support frame. The wheel chair, as described, has added stability as relative pivoting of the rear wheel support frame and the front wheel support frame maintains the wheels in contact the ground at all times.
