Abstract

An insulation element for insulating a structural element in a vehicle includes a support element having a first surface and a second surface and an expandable material, which is arranged at least on partial areas of the first surface of the support element. The support element has at least one penetration and the expandable material projects through the penetration and forms a protrusion on one side of the second surface of the support element. The protrusion is dimensioned and the expandable material designed in such a way that the protrusion has a larger cross section after expansion than a cross section of the penetration.

First claim

The invention claimed is:

1. An insulation element for insulating a structural element in a vehicle, the insulation element comprising
a support element having a first surface and a second surface, and
an expandable material, which is arranged at least on partial areas of the first surface of the support element,
wherein
the support element has at least one penetration and the expandable material projects through the penetration and forms a protrusion on one side of the second surface of the support element,
the protrusion has a constant cross section, and
the protrusion is dimensioned and the expandable material designed in such a way that the protrusion has a larger cross section after expansion than a cross section of the penetration.

2. The insulation element according to claim 1 , wherein the cross section of the penetration and the cross section of the protrusion have an identical shape.

3. The insulation element according to claim 1 , wherein the cross section of the penetration and the cross section of the protrusion have a substantially equal area.

4. The insulation element according to claim 1 , wherein the protrusion is of a cylindrical design.

5. The insulation element according to claim 1 , wherein the cross section of the protrusion is circular, elliptical or oval.

6. The insulation element according to claim 1 , wherein the cross section of the protrusion has a maximum diameter of 1 to 10 mm.

7. The insulation element according to claim 1 , wherein the protrusion has a length of 0.5 to 30 mm, measured from the second surface to a free end of the protrusion.

8. The insulation element according to claim 1 , wherein the support element has a plurality of penetrations, and the expandable material forms a plurality of protrusions.

9. The insulation element according to claim 8 , wherein the penetrations are arranged in an edge region of the support element.

10. The insulation element according to claim 9 , wherein the penetrations are distributed substantially over the entire length along the edge region of the support element.

11. The insulation element according to claim 8 , wherein a spacing between adjacent penetrations is between 5 and 50 mm.

12. The insulation element according to claim 1 , wherein the expandable material forms a single continuous element.

13. The insulation element according to claim 1 , wherein the expandable material has an expansion rate of 300 to 3000%.

14. A system having a structural element and the insulation element according to claim 1 arranged therein.
