The aim of this study was to describe some more realistic driver's postures in light cars and to evaluate their influence on the safety belt restraint efficiency in frontal crashes. First the survey conducted on a drivers sample whose postures have been examined after driving, is presented. Then a dynamic tests series simulated by a dummy is done in order to analyse the influence of parameters such as seat and restraint characteristics, pelvis orientation, body joint stiffness, and body segment modelisation.
