According to the police report, the second leading cause of traffic accident fatality of under 12 years old child is on-board child. Also, more than 50% of injured child from traffic accidents is on board of vehicle. It may results from the lower CRS usage rates especially when child is more than 6 yeard old child, most of children wears a adult seatbelt in stead of using booster seat. But the current requirement of seatbelt anchorage locations are suitable for only adults range from 5%tile female to 95%tile larger male. Static measurement of 6 year old child dummy seatbelt configuration were evaluated based on the allowance limits of UN R14 and FMVSS 210 upper and lower seatbelt anchorages points. The assessment parameters of adult seatbelt fitness for the 6 year old Hybrid III dummy were developed such as D1(distance between shoulder and torso belt), α1( angle between shoulder and horizontal line in x axis of vehicle), α2 (angle of diagonal belt path), D2 (distance between abdomen and lap belt), α3 (angle between lower anchorage point and lap belt contour).

To enhance passengers safety in the event of a car accident, the researches of the vehicle crashworthiness have been constantly conducted. The protection of frontal seat passengers in both driver and front seated occupant has been more focused from the auto industries as well as regulatory bodies more than 40 years. Recently, their interests have been extended to rear seat occupants especially children and female occupants. However, the current available safety devices for the rear seat occupants are seat belt only. According to the previous researchers, the injury level of the rear seat passengers tend to be higher than the injury level of the frontal seat passengers. In this study, the optimal location of seat belts anchorages to enhance rear passengers crashworthiness are studied. FEM models are designed in accordance with regulation of KMVSS 102, ECE R44, ECE R16, and ECE R14. and three point belts are fitted on the HybridIII 5<SUP>th</SUP> percentile dummy and HybridIII 50<SUP>th</SUP> percentile dummy. The combined injury value used HIC15, Nij, Chest deflection, Femur force are used to evaluate the optimal location.
