An attachment is provided for a typical folding wheelchair. The attachment includes a handle or lever which can be pushed downward by the occupant of a wheelchair to raise the seat thereby causing the wheelchair to partially fold and reducing its overall width. A pawl and toothed bracket are provided to selectively hold the chair in predetermined conditions of reduced width. A lifting lever may be positioned either for operation by an occupant or by an attendant and the lever mechanism may be rotated away from the occupant of the chair to avoid restricting his movement. Optional power operated means are also shown which can be used in tandem with or as a replacement for the manually operated means. The power operated means include a battery operated motor and a cable which is pulled or allowed to retract by a crank lever rotated by the motor. Another form of power operated means uses the electric motor to wind a cable on a drum thereby lifting the chair seat to which the cable is connected.
