INFLUENCE OF MASS RATIO AND STRUCTURAL COMPATIBILITY ON THE SEVERITY OF INJURIES SUSTAINED BY THE NEAR SIDE OCCUPANTS IN CAR-TO-CAR SIDE COLLISIONS

In 1344 car-to-car side collisions, the risk of serious or fatal injury to the occupants of struck vehicles seems to increase proportionally with the difference in mass ratios in favor of the striking vehicle. However, in-depth analysis of 63 collisions reveals that the difference in mass ratios is not the principal determinant of injury severity. The frequency and severity of injuries correlates better with the amount of intrusion of the side panel, when the bumper and structure in front off the side rail of the striking car override the rocker panel of the struck car. The relationship between the severity of chest, abdominal and pelvic injuries sustained by occupants seated perpendicularly to the intruding panel and parameters characterizing the colliding vehicles is shown. The paper also discusses structural modifications which might improve protection of occupants involved in side collision with another car.
