The mechanism of injuries and the capability of the human body to tolerate mechanical loads are of fundamental mean, when a safety equipment of a vehicle is to be examined. At the forensic institute of Heidelberg (Prof. Schmidt) a lot of experiments have been carried out and the collected data-sample previous analysed. Deepen analyses with methods like factor-analysis or discriminatory analysis (i.e. logistic location) reveal that human dimensions and some characteristics of human skeleton bones affect the probability of injuries in a side impact more than mechanical measures like thorax acceleration, -deformation, bending of body parts or things like that. In taking this into account the forecast of injuries in the case of suffering a side collision become more acceptable.
