Wheelchair Analysis for Rear Facing Containment Systems

Rear facing wheelchair containment systems on large transit vehicles eliminate the need for the driver’s assistance to secure the wheelchair. This provides a key advantage over the common four belt securement for both transit operators and passengers riding in wheelchairs. The aisle side barrier is the least well developed aspect of the rear facing system. This research characterized several important parameters on different wheelchairs in order to maximize the effectiveness of an aisle side barrier design. The center of gravity locations were determined for five different wheelchairs occupied by a test dummy. Occupied wheelchairs were tilted to determine the motion induced by lateral acceleration, and the amount of force required to prevent motion was measured. The lighter chairs had higher center of gravity locations, which caused them to move more rapidly under smaller lateral accelerations. These chairs required the highest forces to prevent movement. Fifteen different wheelchairs and scooters were measured to determine areas where an aisle side barrier could be placed to prevent the chair from moving during vehicle cornering. The areas measured from all fifteen chairs were composited into a single graph that was used to determine the most appropriate location for an aisle side barrier.
