Impact energy absorbing device for a vehicle, in particular for a rail vehicle, comprising a plurality of elongated first energy absorbing elements (2, 3), each of said energy absorbing elements (2, 3) having a longitudinal axis (2.1, 3.1), a contact end (2.2, 3.2) facing an impact partner and a mounting end (2.3, 3.3) facing said vehicle, each of said absorbing elements (2, 3) being adapted to be deformed in a defined manner along its longitudinal axis (2.1, 3.1) in an impact process with said impact partner, each of said energy absorbing elements (2, 3) having a force to stroke characteristic (6, 7), said force to stroke characteristic (6, 7) representing the course of the deformation force along said longitudinal axis (2.1, 3.1) versus the length reduction of the respective one of said energy absorbing elements (2, 3) during said impact process, each of said force to stroke characteristic comprising a plurality of adjacent force peaks (6.1, 6.2, 7.1, 7.2), wherein said energy absorbing elements (2, 3) are arranged and/or adapted such that said adjacent force peaks (6.1, 6.2) of at least a first one of said force to stroke characteristics (6, 7) are shifted with respect to said adjacent force peaks (7.1, 7.2) of a second one of said force to stroke characteristics (6, 7). |
