A heat shield suitable for motor vehicles and a method for manufacturing the heat shield is provided. The heat shield is intended to protect temperature-sensitive assemblies, components and connection lines from the direct impact of heat radiation and, possibly, acts as insulation. Moreover, the heat shield may also provide advantageous soundproofing properties. The heat shield is comprised of first and second plates that are at least partially deformable and an insulating material positioned between said plates. Preferably, at least a portion of said insulating material is in the form of compacted powder or flakes.

1. A method of manufacturing a beat shield suitable for use in motor vehicles comprising the steps of:providing first and second plates, each said plate having an edge region and being at least partially plastically deformable;providing an insulating material onto said first plate to cover at least a portion of said first plate;compacting at least a portion of said insulating material; andconnecting said edge region of said first plate to said edge region of said second plate such that said insulating material is positioned between said first and second plate, wherein said insulating material is selected from the group consisting of mica, expanded graphite, perlite, and a mica decomposition.2. A method as recited in claim 1, wherein the form of said insulating material is selected from the group consisting of powder and flakes.3. A method as recited in claim 1, wherein said first and second plates are connected at said edge regions by a connection selected from at least one of the group consisting of a positive connection and a non-positive connection.4. A method as recited in claim 1, wherein said insulating material includes a filler.5. A method as recited in claim 1, wherein said compacting of said insulating material is achieved by movement of said second plate towards said first plate.6. A method as recited in claim 1, wherein said compacting of said insulating material is carried out by a pressing tool in at least one pressing movement.7. A method as in recited in claim 1, including the steps of applying additional insulating material onto at least regions of said first plate and the previously compacted insulating material and compacting said additional insulating material.8. A method as recited in claim 1, further comprising removing said insulating material that is not compacted.9. A method as recited in claim 1, wherein said insulating material is applied substantially evenly on said first plate.10. A method as recited in claim 1, wherein said insulating material is provided on said first plate in the shape of a cone; and wherein said compacting of said insulating material distributes said insulating material on said first plate.11. A method as recited in claim 1, wherein said first plate is partially deformed prior to providing said insulating material.12. A method as recited in claim 11, wherein said first plate is at least partially deformed in the shape of a trough.13. A method as recited in claim 1, wherein an inorganic binding material is applied to said first plate prior to providing said insulating material.14. A method as recited in claim 1, wherein at least one of said plates includes a surface formation to facilitate the distribution of said insulating material upon compaction.15. A method as recited in claim 1, wherein said second plate is at least partially flanged to said edge of said first plate.16. A method as recited in claim 1, wherein the compacting of said insulating material is controlled so that the space between said first and second plates that is not used to physically connect said plates is completely covered with insulating material.17. A method as recited in claim 1, wherein the heat shield is three-dimensionally deformed after said first and second plates are connected.18. A method as recited in claim 1, wherein at least a portion of said first plate is electrostatically charged prior to the application of said insulating material and said insulating material applied to the non-charged portion of said first plate is removed prior to compaction.19. A method as recited in claim 1, including the step of removing a portion of said insulating material from said first plate with a tool that is electrostatically charged in certain regions.20. A heat shield suitable for use in motor vehicles comprising:a first plate that is at least partially plastically deformable;a second plate that is at least partially plastically deformable; andan insulating material that is compacted;wherein said first plate is connected to said second plate and said insulating material is positioned between said first plate and said second plate and is selected from the group consisting of mica, expanded graphite, perlite, and a mica decomposition, and wherein at least one of said first and second plates has a surface with increased roughness as compared to a corresponding surface of said other plate.21. A heat shield as recited in claim 20, wherein said insulating material is in a form selected from the group consisting or powder and flakes.22. A heat shield as recited in claim 20, wherein at least one of said first and second plates is comprised of metal.23. A heat shield as recited in claim 20, wherein at least one of said first and second plates includes a surface deformation.24. A heat shield as recited in claim 23, wherein said surface deformation includes a deformation selected from the group consisting of bulges, beads, or webs.25. A heat shield as recited in claim 20, wherein at least one of said first and second plates includes a surface that is coated with a material that reflects radiated heat.26. A heat shield as in recited in claim 20, wherein the thickness of said insulating material positioned between said first and second plate is varied at different locations between said first and second plate.27. A heat shield as recited in claim 20, wherein predetermined portions of the heat shield are kept free of said insulating material.28. A method for manufacturing a heat shield to be used in motor vehicles, comprising:providing at least first and second external plates;applying an insulating material to one of said first and second external plates so as to at least partially cover said one external plate, said applied insulating material being one of a granular, powder and flake form and free of binding agent;compacting said insulating material into a predetermined contour;positioning said other of said first and second external plates adjacent to said insulating material such that said insulating material is positioned between said first and second external plates; andconnecting said first and second external plates together to capture said insulating material therebetween.29. A method as recited in claim 28, wherein said compacting step takes place before said connecting step.30. A method as recited in claim 28, wherein said insulating material is selected from the group consisting of mica, expanded, graphite, perlite, and a mica decomposition.31. A heat shield suitable for use in motor vehicles comprising:a first plate that is at least partially plastically deformable;a second plate that is at least partially plastically deformable; andan insulating material that is compacted;wherein said first plate is connected to said second plate and said insulating material is positioned between said first plate and said second plate and is selected from the group consisting of mica, expanded graphite, perlite, and a mica decomposition, and wherein at least one of said first and second plates includes a surface that is coated with a material that reflects radiated heat, and wherein the plate positioned on the side of the heat shield that is remote from the radiated heat includes a modification selected from the group of modifications consisting of (a) increased thickness, (b) the inclusion of one or more ribs, and (c) the inclusion of a material having good heat-conducting capacity.
