ABSTRACT:
The wheelchair of the present invention permits a patient to manually rotate handwheels which operate a drive mechanism to selectively propel the wheelchair, raise and lower the wheelchair seat between a standing and a sitting position or raise the footrest for the wheelchair to elevate a patient onto a portion of a wheelchair support seat in the standing position. As the seat moves to a raised position, a front section thereof pivots downwardly relative to a rear section and the rear section is contoured to support the buttocks of a patient.
