Abstract

Heatshield with at least one hole, characterized in that an embossment pattern is arranged around the hole, whereby the embossment pattern comprises of a plurality of protruding elongated elements extending or radiating essentially perpendicular to the perimeter of the hole.

First claim

The invention claimed is:

1. A heatshield, comprising: at least one structural hole extending entirely through the heatshield; and an embossment pattern arranged around the hole, the embossment pattern comprising a plurality of protruding elongated elements that extend or radiate from a perimeter of the hole.

2. The heatshield according to claim 1 , wherein each of the protruding elongated elements extend or radiate from the perimeter at an angle that is between −45 to +45 degrees from a line extending perpendicular to a tangent of the hole at the perimeter.

3. The heatshield according to claim 1 , wherein the protruding elongated elements in the extending direction are formed in at least one shape selected from the group consisting of: a straight shape, a curved shape, an S-shape, and a cornered elongated shape.

4. The heatshield according to claim 1 , whereby the embossment pattern is symmetrically aligned around the hole.

5. The heatshield according to claim 1 , wherein the length of the individual protruding elongated elements is optimized to balance the local differences in stress load.

6. The heatshield according to claim 1 , whereby the protruding elongated elements are starting at the perimeter of the hole.

7. The heatshield according to claim 6 , whereby the embossment pattern comprises additional protruding elongated elements extending perpendicular or radially to the perimeter of the hole, and whereby these additional elements are located between the other elements and start with a distance from the perimeter.

8. The heatshield according to claim 1 , whereby the embossment pattern comprises additional protruding elongated elements and whereby at least one additional element is located between the other elements and connecting the adjacent other elements.

9. The heatshield according to claim 1 , whereby the heatshield is either made of a single layer metal, or a stack of layers whereby at least one outer layer is formed of metal.

10. The heatshield according to claim 9 , wherein the metal is selected from the group consisting of: aluminum, an aluminum alloy, steel, and stainless steel.

11. The heatshield according to claim 1 , additionally comprising means for fastening the heatshield to a vehicle or means for fastening appliances to the heatshield, such that the means for fastening covers at least half of a total area of the embossment pattern around the hole.

12. The heatshield according to claim 11 , wherein the means for fastening covers less than 95% of the total area of the embossment pattern around the hole.

13. The heatshield according to claim 12 , whereby the embossment pattern comprises additional protruding elongated elements extending perpendicular or radially to the perimeter of the hole, the additional elements being located between the other elements and starting with a distance from the perimeter, and the additional protruding elements are at least partly covered by the means for fastening.

14. The heatshield according to claim 11 , whereby the means for fastening are fastened with a predetermined torque to flatten the area of the embossment covered thereby.

15. The heatshield according to claim 11 , wherein the area of the embossment pattern around the hole is at least partially flattened back to an essentially flat area.

16. The heatshield according to claim 2 , wherein at least one of the protruding elongated elements extends from the hole essentially perpendicular to the tangent.
