Abstract
The invention relates to an energy absorption element, comprising at least two multi-chamber hollow profiles (10, 11, 12). Said multi-chamber hollow profiles (10, 11, 12) have a planar profile cross-section with two parallel broad faces. The multi-chamber hollow profiles are arranged serially one behind the other in the energy absorption element, with the broad faces directed towards a possible occurring force (F) and connected to each other by the broad faces. A very high weight-specific energy absorption can be assured by the use of multi-chamber hollow profiles (multiport profiles, in particular, micro-multiport profiles). It is further possible to produce an energy absorption element with a required force/deformation path characteristic.
