Seat belt system consists of mainly four restraining parts, retractor, D-ring, buckle and anchorage. These parts are required rules that are already legislated in many countries to satisfy tensile strength. As a rule belt load is about 800-900kgf in dynamic test and the load is distributed on each parts. So the parts must have enough strength enduring the load. We implemented computer simulation with MARC that is nonlinear static software and presented its simulation procedure and result. Because retractor is the major part which controls spool-in or out of webbing according to acceleration pulse in seat belt system, the deforn13tion of retractor base may cause a serious problem on its function in practical. After original model was evaluated, several alternatives were<br/> suggested to improve the deformation of the base caused by tensile force. Also the design of experiments was introduced to evaluate an optimum mounting hole location of base. Because many parts were directly related to this base and the base was too compact to modify the model, if<br/> possible we tried to find the optimum location which dose not affects parts related to base. Orthogonal array of L,(27) consisted of four variables and two levels. As these variables, Tie-bar position and translation of X, Y, Z were selected. As we got a final mounting hole location through out the main effect and interaction evaluation, designer can make a decision of the location, if the results arc verified trough out several tests. Finally, we got some simulation results of design modification and its reason why happen such deformation modes with the help of nonlinear static simulation, MARC.
