Forward structure of a motor vehicle

1. A forward structure of a motor vehicle, comprising:

a bumper cross member;

an energy absorption element disposed in front of the bumper cross member viewed in a driving direction, the energy absorption element having opposite left and right sides, a rear surface facing the bumper cross member and a forward side contour opposite the rear surface;

a plurality of recesses shaped into the forward side contour of the energy absorption element;

wherein the plurality of recesses include left and right groups of recesses in proximity to the respective left and right sides of the energy absorption element and a center group of recesses between the left and right groups of recesses, the recesses in the left and right groups of said recesses penetrate completely through a depth of the energy absorption element viewed in the driving direction to form breakthroughs arranged in the energy absorption element, the recesses in the center group of said recesses penetrate only partly through the depth of the energy absorption element viewed in the driving direction;

spaced apart crash-boxes, extending at least partially into at least one of the breakthroughs in the left group of recesses and at least partially into at least one of the breakthroughs in the right group of recesses wherein several of the crash-boxes are combined in a left insert, each of the crash-boxes of the left insert extending into a respective breakthrough in the left group of recesses, and wherein several of the crash-boxes are combined in a right insert, each of the crash-boxes of the right insert extending into a respective breakthrough in the right group of recesses.

2. The forward structure according to claim 1 , wherein the recesses are spaced over almost an entire width of the energy absorption element.

3. The forward structure according to claim 1 , wherein the recesses extend at an almost identical level over the entire width of the energy absorption element.

4. The forward structure according to claim 2 , wherein the recesses extend at an almost identical level over the entire width of the energy absorption element.

5. The forward structure according to claim 1 , wherein the crash-box has a truncated cross-section, a base of which is oriented toward the rearsurface of the energy absorption element, a plate extending out from the base of the truncated cross-section in a direction transverse to the driving direction, the base being disposed between the bumper cross member and the energy absorption element.

6. The forward structure according to claim 5 , wherein the crash-box element has a cup shape.

7. A forward structure of a motor vehicle, comprising:

a bumper cross member;

an energy absorption element disposed in front of the bumper cross member viewed in a driving direction,

a plurality of recesses shaped into a forward side contour of the energy absorption element, at least several of said recesses penetrating completely through a depth of the energy absorption element viewed in the driving direction to form several breakthroughs arranged in the energy absorption element; and

a crash-box extending at least partially into one of the breakthroughs, the crash-box element having a cup-shaped defining a truncated cross-section, a base of which is oriented toward a rearward side of the energy absorption element, wherein side walls of the crash-box element are provided with cutouts, whereby webs are formed.

8. The forward structure according to claim 6 , wherein side walls of the crash-box are provided with cutouts, whereby webs are formed.

9. The forward structure according to claim 7 , wherein at least one web has a desired bending point.

10. The forward structure according to claim 8 , wherein at least one web has a desired bending point.

11. The forward structure according to claim 7 , wherein no crash-box penetrates a recess in a defined region of the energy absorption element.

12. The forward structure according to claim 11 , wherein crash-boxes penetrate breakthroughs on both sides of the defined region.

13. An energy absorption element for a forward structure of a motor vehicle, which is disposed in front of a bumper cross member in a driving direction, the element having opposite left and right sides and comprising:

a plurality of recesses spaced inwardly from the left and right sides of the element and shaped into a forward-side outer contour of a main body of the element; and

a plurality of left breakthroughs formed in the energy absorption between the recesses and the left side of the energy absorption element and completely penetrating the main energy absorption element along an entire depth of the energy absorption element in the driving direction, and a plurality of right breakthroughs are formed in the energy absorption element between the recesses and the right side of the energy absorption element along the entire depth of the energy absorption element in the driving direction; and

a left plate substantially adjacent the left side of the element at a portion between the element and the bumper cross-member, a plurality of spaced apart left crash-boxes extending forward from the left plate substantially adjacent the right side of the element and between the element and the bumper cross member, a plurality of spaced apart right crash-boxes extending forwardly from the right plate and into the respective right breakthroughs; wherein

each of the crash-boxes defines a truncated cup shape having side walls formed with cutouts.
