Abstract

An add-on part (1) of a vehicle body, such as a door (1) or tailgate, has interconnected inner and outer parts (2, 4) and reinforced portions (5, 6) and a reinforcing device (7) connecting said reinforced portions (5, 6). The reinforcing device (7) has arms (8, 9, 18, 19), and, in the region of the ends of the arms (8, 9, 18, 19), the reinforcing device (7) is connected in a force-fitting and/or form-fitting manner to the reinforced portions (5, 6). Such an add-on part, while having a structurally simple design and relatively low weight, ensures particularly good stiffening properties.

First claim

What is claimed is:

1. An add-on part of a vehicle body, wherein the add-on part has interconnected inner and outer parts and reinforced portions and a reinforcing device connecting said reinforced portions, the reinforcing device has a plurality of arms, each of the arms of the reinforcing device having a free end region, the free end region of each of the arms having a fork-shaped fastening element fastened in a force-fitting and/or form-fitting manner to one of the reinforced portions facing the respective arm.

2. The add-on part of claim 1 , wherein the reinforcing device is composed of metal or plastic.

3. The add-on part of claim 1 , further comprising a material having a damping effect or a permanently elastic material applied in a region of mounting the reinforcing device in the reinforced portions and/or in contact regions with the inner part and/or the outer part.

4. The add-on part of claim 3 , wherein the material is a plastics layer, or a butyl material.

5. The add-on part of claim 1 , wherein the reinforced portions are portions of the inner part and/or outer part.

6. The add-on part of claim 1 , wherein the add-on part has two supports that form the reinforced portions.

7. The add-on part of claim 6 , wherein the two supports are connected to the inner part and/or to the outer part.

8. The add-on part of claim 6 , wherein the two supports are arranged in a non-curved plane.

9. The add-on part of claim 6 , wherein the two supports are arranged substantially parallel to each other.

10. The add-on part of claim 1 , wherein the reinforcing device has a plurality of arms that are stiffened with one another.

11. The add-on part of claim 1 , wherein the reinforcing device is a reinforcing support with four arms.

12. The add-on part of claim 1 , further comprising at least one support element arranged on the reinforcing device and defining a contact point with one of the reinforced portions or with the inner part or the outer part.

13. The add-on part of claim 12 , wherein the support element is a fin.

14. The add-on part of claim 1 , wherein, for stiffening of the arms with one another, the reinforcing device has two further intersecting arms that are connected on the end sides to the arms of the reinforcing device that are connected to the reinforced portions.

15. The add-on part of claim 1 , wherein the add-on part is a door or tailgate.
