Securing and releasing the apparatus may be controlled by the wheelchair occupant and comprises a latching mechanism which attaches to all types of wheelchairs and which is controlled by a lever easily operated by a wheelchair occupant having only minimum use of one hand. A bar which cooperates with and engages the latch on the wheelchair is attached to a standard which in turn is secured to the vehicle, transport system or structure. A preferred embodiment of the invention further includes a back pad and a head rest and shoulder and seat belt which attaches to the standard.
