Gas leakage properties in numerical models of a SAB (Side Air Bag) need to be estimated without any component testing for a prompt simulation. A reasonable and accurate method for predicting leakage properties, which can be used in MADYMO simulations, is introduced in this study. Leakage functions were formulated with 9 assumptions and coefficients of functions are obtained based on information about components of SABs. The Information and the obtained coefficients were collected as a database. 29 types of drop tower tests were done to build this database. Four types of SABs were chosen and tested to validate the accuracy of the developed prediction method. The resulting correlations between simulations and tests turned out to be sufficiently accurate.
