Impact points and resultant injuries to the head of motor-cyclists involved in accidents with and without crashhelmets.

For a long time, the helmet was obviously attributed an important part in the prevention of head injuries. Attempts to prevent damage of the skull are all in the various helmet designs. Tests are done to obtain the biomechanical standard values of the different helmets. It seems essential to pursue the link of the medical/technical accident analysis and experimental tests. Correlating connections between mechanical evaluations and resulting injury sequences can only be defined by this method.
