Claim 0:
1. An energy absorption device for a bumper of a vehicle, comprising:
a first deformation element, which extends substantially over an entire width of the bumper; and
at least one second deformation element, which is arranged on the first deformation element, in an exterior recess of the first deformation element, wherein
the first and the second deformation element are made of foam material with different densities,
the foam material of the first deformation element has a density which is at least 50 g/l lower than that of the foam material of the second deformation element,
the density of the foam material of the first deformation element is 20 to 50 g/l and the density of the foam material of the second deformation element is 80 to 250 g/l, and
the second deformation element is arranged adjacent to the first deformation element in a longitudinal direction of the vehicle whereby, in an event of a collision, the first deformation element is compressed before the second deformation element is compressed.
