Abstract (en)
[origin: EP2148009A2] The damper has a middle region lying between a head region and an end region, where energy degradation capacity in the end region is smaller than in the middle region. An energy degradation capacity in the middle region is constant. Deformable energy converting cells are arranged in series and include partially different energy degradation capacities below each other. One of the cells is designed as a tubular cylinder, and is filled with an energy degradation material at different filling heights. The cells are provided with reinforced structure elements.
