Steering Assembly Performance and Driver Injury Severity in Frontal Crashes 820474

An analysis of 211 automobiles having the ball-type E.A. device (GM cars - 1972–1980), involved in frontal crashes was made to determine the relationship between driver injury and the steering assembly. The majority of the drivers had MAIS of 0 or 1 (66%). The head was the most frequently injured body region with the lower extremities next in frequency. Of the unrestrained drivers studied, 43% had a thoracic injury, the majority of which were minor. There is no correlation between injury severity and steering rim or spoke deformation, or the amount of E.A. column compression. Specific terminology for certain aspects of the E.A. performance are suggested.
