Abstract
Rollover crashes involving 997 automobile occopants of the front outboard seating positions were reviewed. Injury levels, using the Abbreviated injury Scale, were studied for their association with ejection, restraint use, roof crush, car weight, and the absence or presence of the B-pillar. The results indicate that the more serious injuries and fatalities are sustained by those ejected from the car, with ejection occuring most often through the side glass area. Restraints are related to less severe injuries to the non-ejected occupant as well as to a reduced rate of ejection. Roof crush is found to be a factor that interacts with restraint use and with the vehicle factors.
