Abstract

A clamping element, a fastening arrangement with clamping element, and a method for use of the clamping element are provided. In one example, the clamping element has a first leg and a second leg. The first and the second leg are arranged lying opposite one another. The first and the second leg are connected mechanically via a base region. The base region braces in the first leg in a spring-elastic manner with respect to the second leg on the parts arranged and clamped between the legs.

First claim

What is claimed is:

1. A fastening arrangement of a heat deflector plate on a plastic structure, comprising:
an edge region of the plastic structure, which is exposed to a thermal radiation and thermal convection of a heat source;
an edge region of the heat deflector plate congruent to the edge region of the plastic structure, which has a sound- and heat insulating lamination,
wherein in the edge region of the heat deflector plate and in the edge region of the plastic structure heat-resistant clamping elements are arranged, which press the edge regions of plastic structure and heat deflector plate onto one another with the sound- and heat insulation lamination arranged therebetween; and
wherein the clamping elements further comprise claw tips, and the claw tips of the clamping elements, both in the edge region of the heat deflector plate and also in the edge region of the plastic structure, form notches in a compressed state of the two edge regions such that the clamping elements can only be dismantled by means of a spreading tool.

2. The fastening arrangement according to claim 1 , wherein the plastic structure has a lower edge region, which is exposed to the thermal radiation and the thermal convection of the heat source and has spring steel clamping elements for fixing the lower edge region of the heat deflector plate with the lower edge region of the plastic structure.

3. A fastening arrangement of a heat deflector plate on a plastic structure, comprising:
an edge region of the plastic structure, which is exposed to a thermal radiation and thermal convection of a heat source;
an edge region of the heat deflector plate congruent to the edge region of the plastic structure, which has a sound and heat insulating lamination, and
wherein in the edge region of the heat deflector plate and in the edge region of the plastic structure heat-resistant clamping elements are arranged, which press the edge regions of plastic structure and heat deflector plate onto one another with the sound and heat insulation lamination arranged therebetween,
wherein the plastic structure has a plastic panel on an upper crossmember of a vehicle body beneath a windshield and above a turbocharger of an internal combustion engine.
