The work described in the report was initiated amid concerns that increased belt usage would increase the frequency of facial injuries resulting from steering wheel contact. By 1986, three different devices had been developed to assess facial injuries. The Transport and Road Research Laboratory (TRRL) had developed a honeycomb test procedure and a safety steering wheel. Other devices were also being proposed by Transport Canada and Volvo/Collision Safety Engineering (CSE). The device proposed by Transport Canada was a methyl acrylic frangible dummy facial insert, while the Volvo/CSE device had piezoelectric pressure sensors incorporated into the dummy head form. These three devices were tested to determine their ability to assess injury under impact conditions which duplicated cadaver facial testing. Based on these tests, the TRRL procedure was selected for further evaluation. The TRRL honeycomb procedure was evaluated in both static and dynamic loadings. The procedure was then used to evaluate the TRRL safety steering wheel and production steering wheels. The honeycomb test procedure indicated that the safety steering wheel would be expected to produce fewer facial injuries than standard production wheels. Comparison with cadaver tests, however, indicated that the safety wheel provided little benefit over standard production wheels, brining the validity of the TRRL honeycomb procedure into question.
