The invention relates to an impact energy absorbing device for vehicles. The invention is suited, but not limited to, for use in rail vehicles. The aim of the invention is to provide an impact energy absorbing device, which also fulfils future requirements with regard to crash safety. In order to enable a larger working travel without having to increase the amount of force, the energy absorbing process is spatially displaced. The impact energy absorbing device comprises activatable or deactivatable means for absorbing impact energy. In one embodiment a front part of the rail vehicle is extended, swung out and/or pushed out counter to the direction of impact especially counter to the direction of travel, when these means are activated, and afterwards, the produced space is at least partially, in particular, completely filled with energy absorption elements. In another embodiment, which can also be combined with the aforementioned embodiment, spaces which exist at least between two adjacent and interspaced parts of the vehicle, in particular between two cars of a train, are at least partially, in particular, completely filled with energy absorption elements when the means for absorbing impact energy are activated.
An impact-energy dissipation device for vehicles, in particular rail-bound vehicles, characterized by means for impact-energy absorption capable of being activated or deactivated, said means for impact-energy absorption consisting therein that, when the means for impact-energy absorption are activated, a front part of the vehicle is moved out, swivelled out and/or pushed out against the impact direction, in particular against the direction of travel, and the intermediate space created by the moving out, swivelling out and/or pushing out of the front part is then filled at least partially, in particular completely, with energy absorption elements, and/or that intermediate spaces existing at least between two neighbouring and spaced parts of the vehicle, in particular between two wagons of a train, are filled at least partially, in particular completely, with energy absorption elements.
