Main-Scenarios for this helmet are impacts from the front, rear and side. For example, in street skating there is no protection of the upper region of the head needed, because the maximum height of the fall prevents skaters from falling on top of their heads. To prevent damage to the skull in general, the energy of the impact is spread to a bigger area.
For illustration, the results of the first 3D-calculations show a helmet and a human skull. Furthermore there are shown several 2D-patterns.
In view of all the results, a CAD model was created.
