Abstract
A deformation element having a single or multi-chamber hollow section with a longitudinal axis to accommodate energy of impact acting in the direction of the longitudinal axis of the section. The deformation element contains outer section walls that form inner and outer section wall faces. The outer section walls are divided into section wall end lengths and lengths and section wall intermediate lengths, whereby the abutting section wall end length of a pair of outer section walls form corner regions with corners. The wall thicknesses of the section wall end lengths are greater than the wall thickness of the section wall lengths neighboring the section wall end lengths, with the result that a thickening of the section wall is provided in the corner region.
