Abstract
An energy absorber for use as impact protection in a motor vehicle, in particular in the region of the doors, is provided. The energy absorber can be formed as a plastics material component and comprises a plurality of ribs which together form polygonal hollow chambers. In manufacturing the energy absorber, a tool parting line of the manufacturing tool is defined such that the parting line defines at least two regions of the energy absorber displaying differing energy absorption characteristics. Upon impact, the energy absorber follows a force/distance curve which first rises linearly and then continues constantly.
