The Interaction of Air Bags with Upper Extremities

Recently there has been a greater awareness of the increased risk of certain injuries associated with air bag deployment, especially the risks to small occupants, often women. These injuries include serious eye and upper extremity injuries and even fatalities. This study investigates the interaction of a deploying air bag with cadaveric upper extremities in a typical driving posture; testing concentrates on female occupants. The goals of this investigation are to determine the risk of upper extremity injury caused by primary contact with a deploying air bag and to elucidate the mechanisms of these upper extremity injuries. Five air bags were used that are representative of a wide range of air bag ‘aggressivities’ in the current automobile fleet. This air bag ‘aggressivity’ was quantified using the response of a dummy forearm under air bag deployment.

Pedestrian Injuries and the Downsizing of Cars

The Pedestrian Injury Causation Study (PICS) is used to investigate the relations between car weight and pedestrian injuries in frontal accidents. As car curb weight decreased, large changes in overall severity are not observed, although the proportion of head injuries increases. Since contacts of the windshield area are more common in smaller cars, they are studied in detail.

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 the 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.
