摘要： The wheel chair of this invention has its seat member supported for raising and lowering on a chassis having a castering rear wheel and two relatively small front wheels rotatable on a common axis, each driven independently of the other by a reversible electric motor. A brake member is pivoted to the chassis to swing up from and down to an extended position in which the rear wheel is above the surface and the brake member cooperates with the front wheels to support and immobilize the wheel chair. Swinging legs so support the chair element on the chassis that as the chair element is lowered it moves forward over the footrest so that the footrest does not hamper the occupant in transferring to and from the wheel chair.
