Abstract
The present invention relates to an energy dissipation device with a first force-transferring element, a second force-transferring element, and a first and second energy dissipation element which are disposed in the energy dissipation device such that the force flow taking place during the transfer of the tractive and impact forces in the longitudinal direction of the energy dissipation device runs parallel through the two energy dissipation elements. By the activation behavior of the individual energy dissipation elements being chosen appropriately, the total characteristic curve of the energy dissipation device can be precisely determined in advance. In particular, the invention makes possible the construction of energy dissipation devices with force-path characteristic curves with regions of the characteristic curve, which fall off sharply. For this, characteristic curve contours are possible in particular in which, to trigger the energy dissipation device, a greater force is required than during the actual energy dissipation.
