Abstract

A tailgate for a motor vehicle includes a metallic main body and at least one fiber-reinforced tape disposed on and/or in the metallic main body. The at least one fiber-reinforced tape has reinforcement fibers embedded in a matrix material composed at least in part of a metallic material. The tailgate can include at least one additional component that is at least in part embedded in the main body. The at least one additional component can have at least one connection portion and a loop of the fiber-reinforced tape can be guided around the at least one connection portion.

First claim

What is claimed is:

1. A tailgate for a motor vehicle comprising:
a metallic main tailgate body;
at least one additional component with at least one connection portion, wherein the at least one additional component is at least in part embedded in the metallic main tailgate body; and
at least one fiber-reinforced tape with reinforcement fibers embedded in a matrix material, wherein a loop of the fiber-reinforced tape is guided through the at least one connection portion of the at least one additional component and the at least one fiber-reinforced tape is one of disposed on the metallic main tailgate body, disposed in the metallic main tailgate body, or disposed on the metallic main tailgate body and in the metallic main tailgate body, and the matrix material is at least in part composed of a metallic material.

2. The tailgate according to claim 1 , wherein the metallic material is aluminum or magnesium.

3. The tailgate according to claim 1 , wherein the fiber-reinforced tape is connected indirectly to the metallic main tailgate body by an adhesive.

4. The tailgate according to claim 1 , wherein the fiber-reinforced tape is connected directly to the metallic main tailgate body in a materially integral manner.

5. The tailgate according to claim 1 , wherein the matrix material is die cast to the metallic main tailgate body.

6. The tailgate according to claim 1 further comprising another additional component with at least one connection portion, wherein the another additional component is at least in part embedded in the metallic main tailgate body and a loop of the fiber-reinforced tape is guided through the at least one connection portion of the another additional component.

7. The tailgate according to claim 1 , wherein the at least one additional component comprises a fastening element for a tailgate lock, wherein the fastening element comprises two laterally disposed connection portions, the fastening element is at least in part embedded in the metallic main tailgate body, and a loop of the fiber-reinforced tape is guided through the at least one connection portion.

8. The tailgate according to claim 7 , wherein the fastening element is partially or completely produced from a metal or a metal alloy.

9. The tailgate according to claim 7 , wherein the fastening element and the matrix material are die cast to the metallic main tailgate body.

10. The tailgate according to claim 7 , wherein the matrix material is die cast to the metallic main tailgate body.

11. The tailgate according to claim 1 , wherein the matrix material is completely composed of the metallic material.

12. The tailgate according to claim 11 , wherein the metallic material is aluminum or magnesium.

13. The tailgate according to claim 1 further comprising a window opening, wherein the fiber-reinforced tape is disposed so as to encircle the window opening.

14. The tailgate according to claim 13 , wherein the fiber-reinforced tape encircles a peripheral region of the metallic main tailgate body.

15. A tailgate for a motor vehicle comprising:
a metallic main tailgate body;
at least one additional component at least in part embedded in the metallic main tailgate body, the at least one additional component comprising at least one connection portion; and
at least one fiber-reinforced tape with reinforcement fibers embedded in a matrix material, wherein the matrix material is at least in part composed of a metallic material, a loop of the fiber-reinforced tape is guided through the at least one connection portion, and the at least one fiber-reinforced tape is one of disposed on the metallic main tailgate body, disposed in the metallic main tailgate body, or disposed on the metallic main tailgate body and in the metallic main tailgate body.

16. The tailgate according to claim 15 , wherein the metallic material is aluminum or magnesium.

17. The tailgate according to claim 15 , wherein the fiber-reinforced tape is connected indirectly to the metallic main tailgate body by an adhesive.

18. The tailgate according to claim 15 , wherein the fiber-reinforced tape is connected directly to the metallic main tailgate body in a materially integral manner.

19. A tailgate for a motor vehicle comprising:
a metallic main tailgate body with a window opening;
a fastening element for a tailgate lock connected directly to the metallic main tailgate body in a materially integral manner, the fastening element comprising two laterally disposed connection portions; and
at least one fiber-reinforced tape with reinforcement fibers embedded in a matrix material and disposed so as to encircle the window opening, wherein the matrix material is at least in part composed of a metallic material, the at least one fiber-reinforced tape is connected directly to the metallic main tailgate body in a materially integral manner, and a loop of the fiber-reinforced tape is guided through the two laterally disposed connection portions.

20. The tailgate according to claim 19 , wherein the matrix material is die cast to the metallic main tailgate body.
