An energy absorption device for a vehicle

摘要

An energy absorption device 10 for a vehicle is provided. The energy absorption device 10 comprises: a first energy absorption element 12 made of a first energy absorbing material 14; and at least one second energy absorption element 16 made of a second energy absorbing material 18 that is different from the first energy absorbing material 14. The energy absorption elements 12, 16 are arranged successively in the longitudinal direction of the vehicle. The energy absorption device 10 further comprises: a first support element 22; an impact element 24; a first guide 32 along which the impact element 24 is movable towards the first support element 22 in the longitudinal direction of the vehicle due to an impact; a second support element 34 connected to the structure 36 of the vehicle; a second guide 38 along which the first support element 22 is movable towards the second support element 34 in the longitudinal direction of the vehicle due to an impact. The second energy absorption element 16 is arranged between the first support element 22 and the second support element 34.
