Abstract :
The development of a new seat-adjustable power wheelchair is presented in this paper. To prevent pressure ulcers from long periods of sitting, a seat-adjustable mechanism was designed. The lower rear portion of the power wheelchair is movable along a ball screw, so as to change the tilting angle of the seat of the wheelchair to allow the patient to be able to change the high pressure area of the bottom. The mechanism can also be employed to shift the center of gravity of the wheelchair to increase the stability while the wheelchair is moving.
