Abstract

A shielding component, in particular a heat shield, has at least two shield components (10, 12) which can be connected to each other by a connection unit (14). Because the connection unit (14) has a guide (16) which enables adjustment of the relative positions of the individual shield components (10, 12) to each other and which is used for fastening in the adjusted position. A sliding heat shield concept arises in which, with a heat shield having several shield components, adaptation is possible on site to the geometrical conditions of engines and their add-on parts including exhaust systems. Effective sound damping and heat insulation can be produced in a wide area with only one shielding component and its shield components.

Claims

1. A shielding component for forming a heat shield for combustion engines, comprising:

first and second shield components; and

a connection coupling said first and second shield components to one another, said connection including a guide enabling adjustment of positions of said first and second shield components relative to one another and fixing of said first and second shield components in adjusted relative positions, said guide being a guide slot in said first shield component elongated along at least one adjustment movement path and at least one guide part extending in and movable in said guide slot along said adjustment movement path, said guide part having a projection at one end overlapping said guide slot and an opposite end retained in said second shield component.

2. A shielding component according to claim 1 wherein

said shield components are shell shaped covers aligned along a common longitudinal axis parallel to said adjustment movement path.

3. A shielding component according to claim 1 wherein

said second shield component comprises at least one elongated guide slot for adjustably fastening said second shield component to a vehicle component.

4. A shielding component according to claim 1 wherein

each said shield component has multiple layers.

5. A shielding component according to claim 1 wherein

each said shield component is a formed sheet metal part.

6. A shielding component according to claim 1 wherein

each said guide part has smaller dimensions along the adjustment movement path than said guide slot.

7. A shielding component according to claim 1 wherein

said guide part comprises a fastener for retaining said first and second shield components in the adjusted relative positions.

8. A shielding component according to claim 7 wherein

said fastener is a screw with a head forming said projection and extending laterally beyond said guide slot on said one end thereof.

9. A shielding component according to claim 7 wherein

said fastener is a rivet with a head forming said projection and extending laterally beyond said guide slot on said one end thereof.

10. A shielding component according to claim 7 wherein

said fastener is a thread pin with a threaded nut forming said projection and extending laterally beyond said guide slot on said one end thereof.

11. A shielding component according to claim 1 wherein

one of said shield components has an overlap extending over and contacting a portion of the other shield component to guide relative movement therebetween.

12. A shielding component according to claim 11 wherein

said overlap ends at an edge on an exterior side of said one of said shield components, and forms a stop opposite a free edge of the other of said shield components;

and

said adjustment movement path extends within said overlap.
