The aim of this Master’s Thesis is to study and analyze the effects of different altitudes on airbag deployment and its components. This project was conducted in collaboration with Italdesign- Giugiaro S.p.A. The first and second chapters are the theoretical part of this thesis. In particular, in the first chapter there is an introduction on airbag mechanism and its components. The second chapter describes the validation phase of an airbag, detailing the types of tests performed and the test conditions. The last two chapters, instead, are the practical part, with simulations, tests and potential corrective factors for high altitudes. The third chapter analyzes the effects of atmospheric conditions on airbags, with a focus on altitude.
