Nihon University and Nippon Medical School research the traffic accident. This study analyzed anatomical damage and the vehicle damage of the findings from medical and engineering. Abdominal injury is the largest in seatbelt user's death and serious injury rate. Generating mechanism should be solved fast. The research example which abdominal injury occurred had the feature which the sheet bearing has damaged. It case had been suffered abdominal injury seatbelt is removed from the pelvic region. Abdominal injury, it is necessary for the anatomical evaluation of AIS of bleeding increases with time, even minor injuries. To simulate the behavior obtained from the survey crew, we want to clarify the generation mechanism of abdominal injury.
