Fig. 4a shows a diagrammatic illustration of an energy absorption device 100 according to the invention in a starting position, that is to say a position, in which the energy absorption device 100 is not deformed.
The energy absorption device 100 comprises a first fastening element 110 which can be connected to the vehicle chassis 2 or the vehicle hull 2' of the vehicle 1. The first fastening element 110 is configured as a panel or sheet and, in the installed state, is connected to the vehicle chassis 2 or the vehicle hull 2'.
Furthermore, the energy absorption device 100 comprises a second fastening element 120 which can be connected to the vehicle element 10 which is to be protected. The second fastening element 110 is preferably likewise configured as a panel or plate and, in the installed state, is connected to the vehicle element 10.

In order to achieve sprung mounting of the vehicle element 10 by way of the energy absorption device 100, the webs 130, 140, 150, 160 are in each case of flexurally elastic configuration.
The length of the webs 130, 140, 150, 160 can differ from one another, with the result that, for example, a first web 130 and a fourth web 160 which are connected to the fastening elements 110, 120 are shorter than a second web 140 and third web 150.
The different length of the webs 130, 140, 150, 160 achieves a situation where they can compress elastically to a different extent, and the result is a defined bending Date Recue/Date Received 2023-06-21
