Abstract
A hydraulic seat-rise wheelchair constructed/or a patient experiencing severe difficulty getting into and out of a wheelchair is described. The seat-rise mechanism, activated by a hydraulic cylinder, is constructed to locate within a wheelchair frame replacing the seat and back of a normal manual wheelchair. Patient control of the lifting and lowering feature is maintained by controls fitted to the arm of the wheelchair. A wheelchair of this design is most suitable for use by patients who, by virtue of their disability, require it to achieve greater independence.
