Abstract

A heat shield includes a plurality of elements for shielding temperature-sensitive components. The elements are substantially matched to the respective contour of the component which is to be shielded and which at least partially overlap one another. The elements are fixed but moveable relative to one another in an overlapping region.

Claims

1. A heat shield for shielding components influenced by temperature, comprising:

a pair of heat shield elements, said heat shield elements being contoured to conform essentially with the contour of the components to be shielded, said heat shield elements at least partially overlapping one another in a overlapping region of said heat shield elements,

said overlapping region of at least one of said heat shield elements including a projection having a plate-like structure facing in the direction of the other heat shield element,

each of said overlapping regions of said heat shield elements including an opening,

a fixing element disposed in said openings for fixing said heat shield elements to one another and allowing said heat shield elements to move relative to one another in said overlapping region, and

said fixing element including a leg projecting through said openings and a pair of leg regions extending from and perpendicular to said leg, wherein said leg regions are disposed between said heat shield elements.

2. The heat shield according to claim 1, wherein said fixing element has a cross-shaped cross section.

3. The heat shield according claim 1, wherein at least one of said opening and said recess comprises an oblong hole.

4. The heat shield according to claim 1, wherein at least partial regions of said heat shield elements in said leg regions of said fixing element have profiles facing in the direction of said leg regions.

5. The heat shield according to claim 1, wherein said fixing element includes a flange spaced from said leg regions.

6. The heat shield according to claim 1, wherein said fixing element is hollow and includes a flange-forming rivet.

7. The heat shield according to claim 1, comprising a heat shield of an exhaust manifold of a vehicle.

8. The heat shield according to claim 1, comprising a heat shield of an exhaust manifold and adjacent exhaust gas turbocharger.

9. The heat shield according to claim 1 wherein said heat shield elements have different contour designs.

10. The heat shield according to claim 1 wherein said leg regions extend parallel to said heat shield elements.
