미국 정면 New NCAP 대응 구속장치 기술 연구

National Highway Traffic Safety Administration (NHTSA) has released revised New Car Assessment Program (NCAP) in July 2008. New frontal NCAP includes the enhanced contents that are extended body injury areas, down injury scale levels and change of the passenger dummy to 5%ile female. Injury probability of new frontal NCAP was increased compared to current one for the same vehicles according to NHTSA research tests. On this study, we analyzed the injury mechanism of each body region (head, neck, chest and femur) and found the countermeasures of restraint systems. The characteristics of airbag, seatbelt and knee bolster are presented to help their design for new frontal NCAP.
