Safety performance of a new car is evaluated through USNCAP and their results in the star rating are provided to the consumers. It is very important to obtain high score of USNCAP to appeal their performance to consumers. Therefore the car companies have made the effort to improve their car safety performance. These efforts should satisfy the demand not only to get high score but also to pass the FMVSS, NHTSA regulations on safety. In this study, restraint system had been optimized to minimize the injury of female passenger. Belted 5th%ile female frontal crash test was selected from various test methods of USNCAP for the study. The combination injury probability of USNCAP was selected as an objective function. And the injury limit value, which was defined in FMVSS, was set to an optimization constraint. Belted 5t%tile female frontal crash test computer simulation model and unbelted 50th%tile male frontal crash test computer simulation model was developed. Many researches that were similar to this study had been conducted, however most of them had limitation that interaction between airbag and safety belt had not been considered. Contrary to these researches, the interaction was considered in this study. Ultimately, optimal combination of Restraint system’s design parameters was obtained and injury pattern was analyzed.
