| 摘要 |
The present invention relates to an energy absorption apparatus having a first hollow longitudinal section ( 2 ) with a first cross-sectional width ( 5 ) and a second hollow longitudinal section ( 3 ) with a second cross-sectional width ( 6 ) and having an overlapping transition region ( 4 ) between the hollow longitudinal sections. The invention also relates to a method for producing an integral energy absorption apparatus. In order to provide an energy absorption apparatus having an easily determinable deformation response, the second hollow longitudinal section is designed to have a higher strength than the first hollow longitudinal section. In the method according to the invention for producing an energy absorption apparatus, a tube with a first cross-sectional width is narrowed, in sections, to the second cross sectional width so as to form the hollow longitudinal sections and the tube is compressed, as a result of which the overlapping transition region is formed.
