Assessment of injury risk to children from side airbags.

Static out-of-position tests were performed to identify the potential for injury as a function of position, airbag type and vehicle seat characteristics. Seat and door mounted airbags, head curtains and head tubes were evaluated. Out-of-position testing was carried out with the Hybrid III 3 year old, 6 year old and the TNO Q3 3 year old child dummies. In-position tests and a dynamic test were conducted to monitor child seat and airbag interactions and to confirm that properly restrained children would not be exposed to undue risk from a deploying side airbag. Results of the out-of-position testing suggest that current side airbag designs may cause serious and/or fatal neck and chest injuries. In-position static testing with child seats suggested a potential for intrusion into the child occupant space leading to structural damage of the car seat.

Toward a comprehensive biomechanical injury cost model.

The proposed biomechanical injury cost model utilizes surrogate-based injury assessment functions to predict the probability of occurrence and the probable cost of specific injuries to the head, thorax, abdomen, and lower extremities. The resulting probability cost is a function of the number, location, and severity of injuries. As more precise injury assessment functions and more accurate cost estimates become available, the model will become an effective tool for comparing and classifying different injury patterns.
