Reinforcement element for a lower region of a front bumper and front bumper for a motor vehicle provided with the same
View Patent ↗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 in case of the impact of a lower leg section against the lower impact region of the front bumper. Here the reinforcing element adjoins the lower region of the front bumper in the direction of travel behind the lower region of the front bumper. The reinforcing element has a base plate with reinforcing ribs attached thereto. It extends substantially in a horizontal direction, approximately across the width of the front bumper. Here for the first time it is proposed that the reinforcing element with its rear end in the longitudinal direction is at least partially supported against a cross strut arranged below the engine compartment. Further, the above invention proposes for the first time a front bumper equipped therewith for a motor vehicle.
1. Reinforcing element for a lower impact region of a motor vehicle front bumper for the protection of pedestrians in case of the impact of a lower leg section against the lower region of the front bumper, wherein the reinforcing element adjoins the lower region of the front bumper in the direction of travel (X) behind the lower region of the front bumper, has a base plate with reinforcing ribs attached thereto, and extends substantially in a horizontal direction approximately across the width of the front bumper, characterized in that the reinforcing element is at least partially supported by means of its rear end in the direction of travel (X) against a cross strut arranged below the engine compartment.
2. Reinforcing element according to claim 1 , characterized in that the cross strut is part of an auxiliary frame linked to the vehicle body.
3. Reinforcing element according to claim 1 or 2 , characterized in that the reinforcing element is attached directly to the auxiliary frame cross strut by adhesion.
4. Reinforcing element according to claim 1 , characterized in that the reinforcing element is supported by its rear side at least in sections against the facing front side of the auxiliary frame cross strut, and the two components are joined together by means of a fastening strut located above these two components.
5. Reinforcing element according to claim 1 , characterized in that the reinforcing element is designed as a separate plate which is adapted to be integrated in the lower bumper region.
6. Reinforcing element according to claim 1 , characterized in that the reinforcing element is adapted to be mounted on the lower bumper region by adhesion.
7. Reinforcing element according to claim 1 , characterized in that the reinforcing ribs extend downwardly from the base plate which is at the top with its rear side facing towards the engine compartment.
8. Reinforcing element according to claim 1 , characterized in that the reinforcing element is at least partially encased like a shell in a front section in the direction of travel (X), by the lower bumper region.
9. Reinforcing element according to claim 1 characterized in that the reinforcing ribs ( 21 ) extend substantially at right angles from the base plate and are molded from the same material integrally thereon.
10. Reinforcing element according to claim 1 , characterized in that fastening points, are formed in the base plate between the reinforcing ribs.
11. Reinforcing element according to claim 1 , characterized in that the fastening points in the base plate correlate with corresponding fastening points in the shell of the lower bumper region, which are designed as latching openings.
12. Reinforcing element according to claim 1 , characterized in that the base plate has, in the rear region in the longitudinal direction of the vehicle (X), cross-shaped reinforcing ribs which are adjoined at the front by longitudinal ribs arranged parallel to each other and oriented substantially in the longitudinal direction.
13. Reinforcing element according to claim 1 , characterized in that the base plate on its rear side facing towards the engine compartment has a radiator deflecting device.
14. Reinforcing element according to claim 1 , characterized in that it is made of plastic.
15. Front bumper for a motor vehicle having a first impact region which is to come into contact with a bumper bar of another motor vehicle, as well as having a second impact region which is arranged below the first impact region and which is to come into contact with a pedestrian's lower leg section, wherein the bumper has an outer shell and is supported in the first impact region, via an absorber element arranged therebetween, against a cross member which is mounted by means of crash boxes on the longitudinal members of the body, characterized in that in the longitudinal direction of the vehicle (X) behind the second, lower impact region there is provided a reinforcing element which is at least partially supported by its rear end in the direction of travel (X), against a cross strut located below the engine compartment.
