Abstract

A fastening arrangement with damping effect, consisting of two structurally identical fastening units each having a central first through opening. Each fastening unit comprises a mounting element and a damping element. The mounting element is disc-shaped with a central second through opening and an identical detent structure extends from a first side of each mounting element. The damping element is disc-shaped with a central third through opening and is arranged at last partially in the central second through opening of the mounting element. Due to this construction the two fastening units can be fastened to one another by means of the mutually facing first sides having the identical detent structure of the respective mounting elements with first component arranged between them.

First claim

The invention claimed is:

1. A fastening arrangement with damping effect consisting of two identically constructed fastening units with a central first thru-opening each, and each fastening unit includes:
a. an assembly element as well as a damping element, and
b. the assembly element is formed disk-like with a central second thru-opening and an identical latching structure extends from a first side of each assembly element,
c. the damping element is formed disk-like with a central third thru-opening and is arranged at least partly in the central second thru-opening of the assembly element, so that
d. the two fastening units are fastenable at each other via the first sides, facing each other, with the identical latching structure of the respective assembly elements with first component being interposed.

2. The fastening arrangement according to claim 1 , the latching structure of which extends rectangularly with respect to the abutment surface, that is defined by the disc form of the assembly element, at the first component.

3. The fastening arrangement according to claim 1 , in which each fastening unit furthermore includes a sleeve which is arranged in the central third thru-opening of the damping element.

4. The fastening arrangement according to claim 3 , in which the sleeve is arranged by means of a press-fit in the central third thru-opening of the damping element.

5. The fastening arrangement according to claim 1 , wherein each damping element has a shore A hardness between 40 and 80 shore A and/or a plurality of recesses on a first side, wherein the latching structure of the assembly element and the recesses of the associated damping element are provided on the same side of the respective fastening unit.

6. The fastening arrangement according to claim 1 , wherein each assembly element includes a plurality of latching noses as latching structure, which engage with a corresponding plurality of latching surfaces at the assembly element in the assembled state of the fastening arrangement.

7. The fastening arrangement according to claim 1 , wherein the latching noses are oriented to the radial outside.

8. The fastening arrangement according to claim 7 , wherein each assembly element includes two guiding webs and two recesses on the radial inside, each being arranged radially opposite to one another and in alternation.

9. The fastening arrangement according to claim 7 , wherein each assembly element includes two depressions on the radial outside.

10. The fastening arrangement according to claim 7 , in which the assembly elements of each fastening unit are rotated relative to each other by 90° around the longitudinal axis for the purpose of being fastened at each other.

11. The fastening arrangement according to claim 1 , wherein the latching noses of each assembly element are arranged on a joint circle line and adjacent latching noses show in opposite directions along the circle line.

12. The fastening arrangement according to claim 11 , wherein each assembly element includes a recess between each group of latching noses at the radial outside, in which a corresponding first projection of the damping element is arranged.

13. The fastening arrangement according to claim 11 , wherein each damping element includes a plurality of second projections in accordance with a pair of latching noses on the first side radially inwardly.

14. The fastening arrangement according to claim 11 , in which the sleeve of each fastening unit is configured two-part or with a plurality of breakthroughs.

15. The fastening arrangement according to claim 11 , in which the assembly elements of each fastening unit are rotated with respect to each other by 30° around the longitudinal axis for the purpose of being fastened at each other.

16. A first component with a fastening arrangement according to claim 1 that is arranged in a component opening of the first component.

17. A component connection including a first component according to claim 16 as well as a second component with a second opening and a connecting element, wherein the connecting element extends through the fastening arrangement and engages with a suitable fastening portion in or adjacent to the second component.

18. The component connection according to claim 17 , wherein a radial tolerance compensation is implementable in that each damping element has an inner diameter that is larger than the outer diameter of the connecting element.
