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.

In this study, analysis was conducted using the MADYMO program, and a test and comparative analysis were performed to find the plan area of the D-ring point installed in the C-filler of sports utility vehicles(SUVs). The seatbelt that was used in this study was the ELR type. A SELD test was conducted according to the ECE R16 regulation, and the reliability of the model was confirmed by conducting comparative analysis with the MADYMO analysis model. Then an area that could be planned was set up, and simulation was performed at 5 mm intervals to find the area in which the seatbelt webbing would not deviate from the shoulder, and to check the movement of the chest. As a result, the area of the D-ring point that met the regulation was found. When the D-ring moved 5 mm in the X-axis direction, the movement of the dummy’s chest changed by about 1.30 mm; when it moved by 5 mm in the Y-axis direction, the chest movement changed by about 1.1 mm; and when it moved by 5 mm in the Z-axis direction, the chest movement changed by about 0.45 mm. It is expected that the results of this study can be utilized as a reference by seatbelt designers for planning purposes.

The restraint systems on the front seats of automobiles have been continuously improved in recent years. Thus, the front seats consist of a safety belt with a pretensioner and load limiter to decrease rear passenger"s injuries on frontal crash. In rear seats, however, there is a lack of restraint systems as a pretensioner and load limiter as well as rear seat occupant"s injury is higher than the front seat occupant"s according to the study result for safety. In this study, the load-limiter and pretensioner were modeled to to improve injury severity for rear seat female occupant using the simulation techniques. The design parameters were chosen a pretensioner and load limiter : Load limiter force, pretensioner TTF(Time to Fire), pretensioner inlet. Then, the design variables were optimized using the design of experiment method and Injury assessment method used joint probability of injury in USNCAP. This study investigated the correlation between joint probability of injury and the design variables and minimized injury criteria through various method and the design of restraint systems.

Recently, development in vehicle safety could increase interest in children's safety in vehicle collisions. But the research of children safety in vehicle collisions is not being conducted as many as that of adult's. Especially the study for the vehicle crash was not much. This study focused on the comparison of child safety between test protocols to evaluate children's safety in crash test. Injuries of Q6 and Q10 dummy were evaluated using FFRB (Full frontal rigid barrier) test and 40% ODB (Offset deformable barrier) test with one model vehicle. Even though the limit number of test, the tendency of injury criteria of Q6 and Q10 dummy between the test protocols was not conformed but injury criteria of Q6 and Q10 were not same between FFRB and 40% ODB.

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).
