Abstract
A device to absorb impact energy between an impacted component and a component to be protected from the effects of the impact (in particular between the bumper bracket (1) and the frame side rail of a vehicle). The device has a deforming section (3) to plastically absorb energy (that is between the bumper bracket (1) and the frame rail), and a hydraulic part to elastically absorb energy. The hydraulic part is before the deforming part (3) (viewed in direction of impact) inside the frame side rail. With this design, it is possible to have a large plunger diameter for the hydraulic section and an aluminum construction.
