Abstract
An apparatus adaptable to a wheelchair, for assisting a person seated in the wheelchair to move to a standing position. The apparatus includes opposing pivoting rods as a mechanical leverage lift attached to the bottom of a hinged seat. The action of stepping on the leverage lift device either at the front or at the rear of the chair results in the seated person being lifted. The leverage device lifts the seat from a sitting position to a substantially raised flat position, so that a person sitting in the seat is likewise lifted from a seated position to a partially standing position. The lift mechanism is located at the front and the rear of the wheelchair, depending on whether the person would be assisted by one or two persons in front and/or behind the chair.
