USE OF WHEELCHAIRS AS VEHICLE SEATS; CURRENT PRACTICES AND RECOMMENDATIONS
This report describes the initial results of an engineering study of the use of wheelchairs as motor vehicle seats and of the restraint system used to secure the wheelchair and its occupant in a vehicle. The purpose of this initial study is to test and analyze several types of commercially available wheelchairs and restraint systems using destructive testing techniques and by employing experimental and analytical methods. This phase of the study employs static testing only. It is recommended that further testing, particularly dynamic testing, and more analysis be undertaken in a subsequent and separate investigation. The work reported herein leads to the following conclusions. First, the wheelchair occupant should be strapped directly to the motor vehicle carrying the wheelchair and not to the wheelchair. Second, do not clamp just the rear wheels of the wheelchair to the floor of the vehicle. If the wheels are so locked, then additional restraints must be also be employed. And thrid, some types of restraints are not capable of withstanding longitudinal and/or transverse static loads equivalent to the combined weight of the anthropometric dummy and wheelchair (274 pounds). This is in the range of forces for noncollision conditions of driving. The ultimate goal of this project is to determine a set of requirements which restraint equipment must satisfy in order to be safe and of reasonable quality. The VA can then use these requirements in its standards program for Prosthetics, orthotics and orthopedic aids.
