Determination of the knee-femur-pelvis tolerance from the simulation of car frontal impacts.

Different tolerance criteria for the femur based on different test methodologies are proposed before. In the different research programmes, the human subject was never seated in a vehicle, in a frontal impact situation, and the experiments were not, therefore, sufficiently representative. To determine a criterion which can be practically applied in conditions approaching reality, tests are conducted in an "automobile environment" with the occupant subjected to a series of loads comparable to those a real life victim would experience.
