Far side occupants involved in a rollover or in a side impact experience extensive lateral upper body excursion combined with an increased risk for injuries due to contact with the near side occupant, vehicle structure, partial ejection or webbing. The aim of the research is to show up existing potentials of standard restraint systems to reduce the upper body excursion and related injury risk. Current anthropometric test devices lack biofidelity in case of extensive upper body displacement. The authors use virtual test methods, more precisely the Madymo Human Occupant model. The model was improved to better simulate the behaviour of occupants in lateral low speed tests.
