뒷좌석 승객 충돌안전성 향상을 위한 안전띠 부착장치 최적위치 연구

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 th percentile dummy and HybridIII 50 th percentile dummy. The combined injury value used HIC 15 , N ij , Chest deflection, Femur force are used to evaluate the optimal location.
