A patient transporting device which is capable of functioning as a wheelchair and as a stretcher. The device has a seat assembly which can also be readily converted, while mounted on the frame, to function as a stretcher. The conversion of the seat assembly into a stretcher shifts the seat forwardly relative to the base as the back is folded down to maintain the center of gravity of a patient more centrally located over the base. |
