Abstract

This paper presents the results of experimental studies into wheelchair and occupant restraint systems. The experiments were carried out using a model of a wheelchair place complete with a three-point seat belt and four restraint straps for the wheelchair. The model was tested both in the laboratory and in a minibus during normal travel. The anchor points of the seat belt could be varied. The loads in the restraint system could be measured with load cells. Impact tests were carried out to determine the loads generated and the safety risks the wheelchair could cause. The restraint system consisted of a three-point seat belt and two restraint straps directed backward to secure the wheelchair to a support wall behind the wheelchair. The tests were carried out at speeds and retardations of 30 km/h, 10 g and 50 km/h, 20 g. The forces in the restraint system were measured with load cells. The speed and retardation were measured. The tests were filmed with a high-speed camera. The results obtained form the basis for the Swedish regulations on wheelchair and occupant restraint systems. The paper also presents performance requirements for systems installed in the buses where the traveller is seated in his or her wheelchair.
