Automobile seats playa crucial role of protecting passengers securing them from a car accident. And also those should provide comfort, back-and-forth movement, height adjustment, and many safety and functional parts like side airbag, seatbelt, heater, ventilation device and so on. FEA is one of powerful tools to verify seat strength with complex structures in an early stage of seat development time. To check if the seat meets requirements and safety standards like FMVSS(Federal Motor Vehicle Safety Standards) and ECE, the whole CAD model of seat structure should be prepared for the FEA. In this study, the maximum forces that seat fails at the conditions of rail section peeling test, track pulling test, seat belt anchorage test, and frontal impact sled test have been conducted and compared each other. Main deformed parts at the analysis of whole seat structure were investigated looking at the graph of internal energy of all parts. It is found that reliable relationship exists between component or sub-assembly level test and assembly level test results. The deformed shape of the parts with high internal energy was very similar to the track pulling analysis result. It is found that failure or peeling load of seat belt anchorage analysis ranges 80-85% of the one of track pulling analysis result. Seat belt anchorage test result can be predicted after the analysis of track pulling test. As a result, engineers can reduce their development time and improve their design by ensuring the meet of requirement of full seat structure in advance.
