Abstract

A safety apparatus that holds wheelchairs in place as they are being transported in a motorized vehicle such as a van. The apparatus includes a rigid shaft that extends from the floor of the vehicle to several inches above one wheel of the wheelchair. A frame attaches to the shaft and holds it perpendicular to the floor of the vehicle. Also, a collar is provided which slides on the shaft. A yoke, having a rectangular opening that faces the floor of the vehicle, is attached to this collar. In operation, the top portion of one wheel on the wheelchair is placed within the opening of the yoke. A manually operated clamping mechanism stops the collar from sliding on the shaft during transportation of the wheelchair.
