A detailed analysis of actual traffic accidents involving car passengers wearing seat belts was carried out by an interdisciplinary team. The passengers were examined for the severity of their injuries, the combination of their injuries, and the practicality of their seat belt system. The type of injury to the car, the speed, and the line of impact were related to the injuries. Incorrect use of the belt system, malfunction due to external causes, and construction defects in the seat belt system were described and evaluated according to their specific importance.
