Abstract
An analysis of a sample of lateral collisions has demonstrated that the optimum position for a side impact airbag sensor is in the lower rear quadrant of the front door. Positioned thus, some 88% of AIS 3+ injury cases would be covered, and some 91% of all AIS 4+ cases of front seat occupants would be covered. Analyses of injury sources and anatomical regions receiving injury, especially the head, demonstrate the great preponderance of the door as the prime source followed by exterior objects such as the striking car, trees and poles. Ideas for a predictive analysis of side airbag effectiveness are reviewed. (A)
