Reinforcing element for a lower area of a front bumper, and correspondingly equipped bumper for a motor vehicle
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 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.
1. A reinforcing element for a lower impact region of a front bumper for a vehicle, comprising:
a base plate extending essentially in a horizontal direction approximately over a width of the front bumper;
a plurality of reinforcing ribs attached to the base plate, the plurality of reinforcing ribs extending along said base plate into the lower impact region of the front bumper; and
a plurality of attachment elements, formed in said base plate between said reinforcing ribs, for attaching the base plate to the front bumper, wherein the plurality of attachment elements are latchable projections configured to latch into corresponding latching opening in the front bumper.
2. The reinforcing element according to claim 1 , wherein the latching opening is on a lower bumper region.
3. The reinforcing element according to claim 1 , wherein the plurality of reinforcing ribs extend downwards from the base plate facing towards the engine compartment with the rear side.
4. The reinforcing element according to claim 1 , wherein the plurality of reinforcing ribs extend essentially at right-angles from the base plate and are molded from the same material integrally thereon.
5. The reinforcing element according to claim 1 , wherein the plurality of attachment elements are formed in the base plate between two respective vertical reinforcing ribs traversing the base plate in a first direction and two respective vertical reinforcing ribs traversing the base plate in a second direction.
6. The reinforcing element according to claim 5 , wherein the latching opening is in an outer shell of a lower bumper region correlate with corresponding attachment points in an outer shell of the lower bumper region, which are designed as latching opening is in an outer shell of a lower bumper region.
7. The reinforcing element according to claim 1 , wherein the base plate has cruciformly designed reinforcing ribs in a rear region in a vehicle longitudinal direction to adjoin the ribs orientated essentially in a longitudinal direction and arranged parallel to one another towards the front.
8. The reinforcing element according to claim 1 , further comprising a radiator deflection device protruding upwards from the base plate and is positioned in front of a radiator in the engine compartment.
9. The reinforcing element according to claim 1 , wherein the reinforcing element is produced from plastic.
10. A front bumper for a motor vehicle, comprising:
a first impact region, configured to first come into contact with a bumper of a second motor vehicle during a crash, and
a second impact region, arranged below the first impact region, configured to first come into contact with a lower leg section of a pedestrian during a crash,
an outer shell configured to surround the first and second impact regions;
an absorber element provided behind, in a vehicle longitudinal direction, the first impact region which is mounted by means of a crash box,
a reinforcing element being provided behind, in a vehicle longitudinal direction, the second impact region, the reinforcing element comprising a plate and reinforcing ribs extending along the plate into a front portion of the reinforcing element which is surrounded by the outer shell at a lower region of the front bumper, and
a plurality of attachment elements, formed in said plate between said reinforcing ribs, for attaching the plate to the outer shell,
wherein the plurality of attachment elements are latchable projections configured to latch into corresponding latching opening in the front bumper.
