1. A bumper arrangement, comprising:
a cross member designed as a hollow profile and having a central region and end regions, said cross member having a front wall, a rear wall, an upper wall and a lower wall, said front wall having a depression which extends in a longitudinal direction of the cross member and has a deepest region which extends at a distance from the rear wall, wherein the upper and lower walls in the end regions of the cross member each have a further depression which extends in the longitudinal direction of the cross member, so that the upper wall and the lower wall in the end regions are depressed more than in the central region of the cross member, so that the distance between the front wall and the rear wall in the end regions is smaller than in the central region of the cross member; and
two deformation elements for arrangement between end regions of the cross member and longitudinal members of a motor vehicle,
wherein the distance between the depression of the front wall and the rear wall at least in the end regions amounts to between including 5 mm and a maximum of 30% of a depth of the cross member as measured in the central region in the longitudinal direction of the motor vehicle.
