As research development of seat frame is being studied actively, the total deformation of seat frame made of high tension steel plate(HTSP) is examined in this study. The seat frame made of SPFC 980 t=2mm with HTSP is tested to obtain total deformation through repeated fatigue durability tester and total deformation is analyzed by simulation under the same condition as experiment. After analyzing by comparing the results of experiment and analysis, structural stabilities of seat frame models with SPFC 780 t=2mm and SPFC 780 t=1.5mm are investigated by FEM analysis on the basis of these results. And it is considered that which model is more suitable at commercial use can be found through this study result.
