Abstract
In this paper optimization techniques together with coupled fluid-structure analysis are used to provide a better understanding of the interaction between the airbag inflation process and an Out Of Position occupant. We provide a concept for, and exemplify how these techniques can be applied to optimize the airbag inflator characteristics in order to minimize occupant injury. For a simplified, but realistic, problem we show that the head acceleration can be reduced by approximately 65 % by optimizing the inlet characteristics.
