An inner diameter D _{Ei of} the energy absorption element 102 is preferably smaller than the inner diameter D _{V of} the cutting element 124 in the area of the projection 130 ,

The energy absorption element 102 can thus by moving the same along the longitudinal axis 110 the energy absorption device 100 by means of the cutting element 124 be machined. In particular, in this case, an outer jacket region 132 of the energy absorbing element 102 from an inner jacket area 134 of Energy absorbing element 102 removed and thereby absorbed energy.

In particular 4 can be seen, extends the inner shell region 134 after energy absorption by means of the energy absorption element 102 by cutting it through the adapter element 104 therethrough.

By the introduction of energy along the energy introduction direction 106 in the energy absorption device 100 first becomes the first layer 112a the energy absorption device 100 subjected to a certain load. Because the first layer 112a only four energy absorption elements 102 includes, is the first layer 112a the least dimensionally stable layer 112 the energy absorption device 100 , so that a deformation of the energy absorption device 100 first in the area of the first layer 112a he follows.

The cutting of the energy absorption elements 102 the second layer 112b takes place in accordance with the cutting of the energy absorption elements 102 the first layer 112a ,

In particular, when the energy introduction direction 106 not parallel to the longitudinal axis 110 the energy absorption device 100 is formed, by means of the first adapter element 104a and the guide device 116 a deflection of the introduced energy take place, so that at least from the first adapter element 104a the introduced energy substantially parallel to the longitudinal axis 110 runs and thus targeted by means of the energy absorption elements 102 the second layer 112b can be absorbed.

Even after the cutting of the energy absorption elements 102 the second layer 112 Energy continues to enter the energy absorption device 100 which is to be absorbed, become the energy absorbing elements 102 the third layer 112c deformed, especially machined.

The cutting of the energy absorption elements 102 the third layer 112c takes place preferably on the second adapter element 104b , which for this purpose along the longitudinal axis 110 is moved. The energy absorption elements 102 the third layer 112c are preferably stationary relative to the structure to be protected 108 ,

The adapter element 104 is in particular designed so that it is partially substantially parallel to a surface 136 the structure to be protected 108 runs.

By using energy absorption elements of different lengths 102 in the first shift 112a the energy absorption device 100 becomes the stepped design of the surface 136 the structure to be protected 108 and the adapter element 104 preferably balanced so that a front side 138 the energy absorption device 100 substantially perpendicular to the longitudinal axis 110 the energy absorption device 100 and / or substantially perpendicular to an energy input direction 106 runs.
