WHEELCHAIR TIE-DOWN SYSTEMS EVOLVE

Despite the fact that 40,000 school buses are used to transport handicapped children daily, there is no federal standard for the crashworthiness of wheelchair tie-down systems and few states have testing requirements for wheelchair tie-downs. Aeroquip Corporation, a Lawrence, Kansas, based manufacturer of wheelchair tie-downs, started in the business after one of its distributors used its cargo tie-downs for some wheelchair passengers. Today Aeroquip builds a system consisting of two main components: tracks made of high strength steel about 5 in. wide and slotted every 2 in., which are bolted to the floor of the school bus; and webbing, which is usually made of polyester or nylon. The standard tie-down method for wheelchairs today is the four-point attachment system. In this system, four straps are attached to strong points on the wheelchair's vertical posts. The straps are attached low to the ground in order to lower the wheelchair's center of gravity and provide more balance. The Aeroquip tie-down system, E-Z-ON vest and the Q'Straint wheelchair and occupant restraint system have all passed 30 mph sled impact tests. Warnings have been issued about mixing the securement systems of different manufacturers, which may cause injuries when accidents occur. Additional information is provided in this article on sled impact testing, the issue of forward facing versus side facing wheelchairs, and studies underway in New York and Michigan on the transportation of handicapped children.
