The biomechanical response of the head during impact loading represents a globally highlighted issue associated mainly with passive vehicle safety. Based on the detection of the dynamic values and biomaterial characteristics during the head impact loading are we able to observe the biomechanical response of biological structures to the loading. The internal mechanical response to the speed vector spreading in both extra- and subdural areas is discussed and its dependency on the characteristics of external mechanical loading. Mathematical and physical models were used for the computational tasks of inverse dynamics that allow the solving of interactional biomechanical conditions in both real and extrapolated extreme-loading situations. Based on the changes of input mechanical loading, i.e., the changes of static, dynamic, impulse and inertial loading, the appropriate biomechanical reaction was able to be determined and the value of the HIC (Head Injury Criterion) specified which can be approximately correlated to the AIS (Abbreviated Injury Scaled) using a table. The knowledge gathered can be applied to all situations when a head hits an obstacle. The mechanisms relate well to the "injury" issues during both work and free time activities, such as transportation, sports, etc.

Keywords: Biomechanics, head injury, impact, passive safety, head injury criterion.
