Arm rests attached to the frame are pivotally mounted for ease in placing the handicapped person into the seat. An optional head rest supports the head of the passenger and a foot support attached to the front of the seat supports the feet of the passenger. A shoulder harness and lap belt are provided for support of the passenger in the seat during travel. A wheeled dolly which removably receives the safety seat is provided for transport of the handicapped person in the seat from the vehicle to another site.
