Abstract: The invention discussed above provides a reinforcing element for a lower impact region of a front bumper of a motor vehicle for the protection of pedestrians during the impact of a lower leg section against the lower impact region of the front bumper. The reinforcing element is thus connected behind, in direction of travel, the lower front bumper region to the latter. The reinforcing element has a base plate with reinforcing ribs attached thereto. It extends essentially in horizontal direction, approximately over the width of the front bumper. It is thus proposed for the first time that the reinforcing element is designed as a separate plate which can be integrated in the lower bumper region. The above invention also discusses a front bumper equipped therewith for a motor vehicle.
