Patent

CA 2416081

The invention relates to a deformation element (1) comprising 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 (1) contains outer section walls (4a,b) that form inner and outer section wall faces (9,10). The outer section walls (4a,b) are divided into section wall end lengths (5a,b) and section wall intermediate lengths (6a,b), whereby the abutting section wall end lengths (5a,b) of a pair of outer section walls (4a,b) form corner regions (2a-d) with corners (3a-d). The deformation element (1) is characterised in that the wall thicknesses (8b,d) of the section wall end lengths are greater than the wall thickness (8a,c) of the section wall lengths (6a,b) neighbouring the section wall end lengths (5a,b), with the result that a thickening of the section wall is provided in the corner region (2a-d).
