Patent ID: 6896317

Claim:
A deformation element comprising a hollow section with a longitudinal section axis to accommodate impact energy acting in a direction of the longitudinal axis of the section by compressing the deformation element in a longitudinal direction, the hollow section having outer section walls that form inner and outer section wall faces, the section walls having section end lengths and corner regions forming corners, the corner regions being formed by two abutting section wall end lengths, the section wall end length in at least one corner region having a wall thickness that is thicker than a wall thickness of a section wall length neighbouring the section wall end length so that there is a thickening of the section wall in the corner region, the corner region with the thicker wall thickness extending at least over a longitudinal section length measured in the longitudinal direction of the section, whereby, in comparison to a deformation element with uniform wall thickness but of an equal shape and overall mass, higher specific energy absorption is achieved, the section wall end length of a corner region having a length that corresponds to at least 5% and at most 45% of a length of a related section wall.
