Vehicle safety has become a major task in the development process of passenger vehicles. Measures for occupant safety are developed by reference to different tests including legal tests and consumer tests. The different load cases for the considered frontal crash tests cause different vehicle kinematics involving all six degrees of freedom. Besides restraint systems, vehicle kinematics shows distinct influence on occupant loading. A sensitivity analysis of the dummy responses due to varied motion fractions has been performed by finite elements simulations of a well-validated simulation model. The influences of particular motion components are determined by objective assessment variables. These are well-known injury criteria as well as geometrical criteria such as distances between dummy and interior. The results of this sensitivity study can be used for additional measures in terms of occupant protection.
