Abstract

A shielding device with a shielding component (17) forming a shield surface, a heat shield in particular, has a clamping component (1) formed to be integral with the shielding component (17) by an extension. The clamping component is folded onto itself at a bending point (29). Two clamping legs (31, 33) are positioned side by side and form the clamping surfaces facing each other to delimit a clamping gap (35) with one end closed at the bending point (29).

Claims

1. A shielding device, comprising:

a heat shield having a primary surface component and a secondary surface component bent at an angle relative to said primary surface component and formed unitarily and as one piece therewith, said secondary surface component having side edges extending approximately in parallel;

a clamping component formed as a unitary, one-piece extension of said secondary surface component and having first and second clamping legs connected by a bending point, said clamping legs being positioned side-by-side and having first and second clamping surfaces, respectively, facing one another and delimiting a clamping gap therebetween, one end of said clamping gap being closed by said bending point extending approximately perpendicularly relative to said side edges of said secondary surface component; and

a tensioning device coupled to said clamping legs for pressing said clamping surfaces against a mounting component positioned in said clamping gap.

2. A shielding device according to claim 1 wherein

said clamping legs have a length extending from said bending point to free ends thereof spaced from said bending point by a leg distance, said primary surface component having a main extent in measured in a parallel direction approximately equal to said leg distance.
