In the case of an automobile seatbelt pretensioner with gunpowder activation as used in passenger vehicles, the seatbelt is retracted by operating a rack and pinion gear using the gas pressure which is generated directly after a crash. In this study, the geometry of a rack and pinion gear is optimized to increase the retracted length and to keep the tension of the seatbelt under 3 kN (this is the value that most automobile companies require). A design program for a rack and pinion gear profile is developed using MATLAB. A three dimensional multibody dynamic model for the seatbelt retractor is created and by applying a rack and pinion gear to the model, its performance is estimated. On the basis of the dynamic simulation results, the optimum profile of a rack and pinion gear is created using the Taguchi method. By comparing the actual test data and the simulation results, the optimization result is verified.
