This paper describes belted dummy injury and roof deformation in rollovers, based on an analysis of field accident investigation results. In the rate of rollover events to the amount of passenger car traffic accidents, occupants' physical injury, and roof crash are studied from analyzing the database originally investigated by the Ministry of Transport in Japan. The ramp roll-over tests are carried out in the laboratory. Comparison of dummy neck loadings and injury criterion (HIC) to the roof crash are presented for production vehicles. By utilizing a three-dimensional Finite Element code (PAM-CRASH), rollover simulations are conducted to observe the behaviour of the roof crash in detail.
