Abstract
A wheel chair with a retractable back rest, and a seat which may be uncovered to expose an opening that enables a patient in the wheel chair to use a toilet while remaining seated in the wheel chair. By actuating a switching arrangement, the patient may raise or lower the back rest to enable the person to be transferred with ease to a bed. A motor operated device may be actuated by the switching arrangement for uncovering an opening in the seat of the wheel chair and the latter may be wheeled directly over a conventional toilet bowl by motors operated selectively through the switching arrangement actuatable by the patient.
