A static test method was developed based upon FMVSS 207, limited 20 g/30 mph sled testing and computer crash simulations in order to evaluate crashworthiness of after-market or add-on wheelchair seating systems (WCSSs). The rigid test wheelchair (WC) frame, surrogate attachment hardware, surrogate support surface, and reference loader gauges were designed and fabricated for the study. Two sets of forty different WC seating components were evaluated. Similar failure modes observed during previously conducted sled impact were observed in the static tests of some of the products. The test method provides a means for evaluating WCSS independent of a specific frame and provides a preliminary screening of crashworthiness.
