The impact girder extruded in a light metal alloy and extending in the vehicle door approximately in the direction of travel can be fixed at both ends in such a way that a profile wall of the impact girder faces towards the inside of the vehicle as the inner flange and a second profile wall of the impact girder provided at a distance from the first forms an outer flange. Fastened to the impact girder is a hollow chamber profile, similarly extruded from a light metal alloy, with at least two profile chambers, the hollow chamber profile protruding into the door box below the impact girder and the profile chambers extending parallel to the latter. The hollow chamber profile provides additional impact protection.
