SUBCOMPACT VEHICLE ENERGY-ABSORBING STEERING ASSEMBLY EVALUATION

This paper describes the results of a 2-year study into the field accident performances of two basic designs of energy-absorbing steering assemblies. The two basic designs are axial-collapse type of steering column used in conjunction with a shear capsule and the self-aligning energy-absorbing steering wheel mounted on a nonstroking column. The study identifies major injury causation factors for these two types of steering assemblies. The analysis was performed on 161 accident cases selected for unrestrained drivers in frontal accidents in two vehicle types.
