Abstract

An insulating element for insulating a structural element in a vehicle including a carrier element having an edge region and an expandable material which is provided at least on the edge region on the carrier element. The expandable material projects beyond the edge region of the carrier element in at least one direction so that the expandable material forms a flexible projection in this at least one direction.

First claim

The invention claimed is:

1. A system having a vehicle structural element and an insulating element for insulating the structural element, said insulating element comprising:
a carrier element having a peripheral region; and
an expandable material which is disposed at least on the peripheral region on the carrier element, wherein, prior to expansion of the expandable material:
(i) the expandable material in at least one direction protrudes beyond the peripheral region of the carrier element such that the expandable material in said at least one direction forms a flexible projection, and
(ii) the flexible projection has at least one protrusion, and the projection is supported on the structural element by way of said protrusion and any contact between the protrusion and the structural element is substantially tangential and/or punctiform.

2. The system as claimed in claim 1 , wherein a length of the projection measured along a plane of the carrier element is between 5 and 50 mm and/or wherein a thickness of the projection measured perpendicularly to the plane of the carrier element is between 2 and 20 mm.

3. The system as claimed in claim 1 , wherein the carrier element has at least one rib which in said at least one direction extends from the peripheral region of the carrier element such that the at least one rib supports the flexible projection.

4. The system as claimed in claim 1 wherein the projection extends substantially in the plane of the carrier element.

5. The system as claimed in claim 1 , wherein the projection extends in a plane which forms an angle in relation to the plane of the carrier element.

6. The system as claimed in claim 5 , wherein the angle is between 10 and 80°.

7. The system as claimed in claim 1 , wherein the projection has a rectangular, a trapezoidal, a triangular, a convex, or a concave cross section.

8. The system as claimed in claim 1 , wherein the projection in an axis perpendicular to the plane of the carrier element extends only above the peripheral region beyond which the projection protrudes.

9. The system as claimed in claim 1 , wherein the protrusion is configured as an arcuate convexity.

10. The system as claimed in claim 1 , wherein the flexible projection of the insulating element is supported on the structural element in at least one location, and wherein the projection is bent on account thereof.

11. The system as claimed in claim 1 , wherein a gap between the projection and the structural element in a region in which the projection is not supported on the structural element is between 1 and 5 mm.
