Abstract

A fastening system for fastening an add-on part on a setting object comprises a setting bolt having a first end and a second end, comprising a fastening section and a load application section, a sealing element with an opening for sealing the setting bolt inserted into the setting object when the setting bolt is arranged within the opening, and the add-on part being fastened on the load application section of the setting bolt.

First claim

The invention claimed is:

1. A fastening system for fastening an add-on part on a setting object by a setting bolt, comprising
a setting bolt having a bolt first end and a bolt second end, with a fastening section and a load application section;
a sealing element having an element first end and an element second end, with an opening for sealing the setting bolt inserted into the setting object when the setting bolt is arranged within the opening, wherein the sealing element consists at least partially of an elastic material; and
the add-on part fastened on the load application section of the setting bolt wherein the sealing element has an axial dimension such that the sealing element abuts on the setting object with the element first end, and on the add-on part and/or the setting bolt with the element second end.

2. The fastening system according to claim 1 , wherein the setting bolt has an axial dimension and the axial dimension of the sealing element amounts to at least 5% of the axial dimension of the setting bolt before the setting bolt is set.

3. The fastening system according to claim 1 , wherein the sealing element has an inside diameter and the setting bolt has a maximum diameter, and the inside diameter of the sealing element is larger than the maximum diameter of the setting bolt such that with the sealing element, an axial section of the setting bolt is in an inserted state between the setting object and the element second end, completely enveloped by the sealing element.

4. The fastening system according to claim 3 , wherein the maximum diameter of the setting bolt is only taken into consideration on an axial section of the setting bolt, on which the sealing element is arranged.

5. The fastening system according claim 1 , wherein the sealing element consists entirely of an elastomer.

6. The fastening system of claim 1 , wherein the sealing element is entirely plastic.

7. The fastening system according claim 1 , wherein the setting bolt has a point on the bolt first end and/or the setting bolt comprises a load application section, and, on the load application section, a device for fastening the add-on part.

8. The fastening system according claim 1 , wherein the sealing element is arranged and/or fastened on the setting bolt.

9. The fastening system according claim 1 , wherein the fastening system comprises the add-on part and the sealing element is arranged and/or fastened on the add-on part.

10. The fastening system according claim 1 , wherein the setting bolt consists at least partially of metal.

11. The fastening system of claim 10 , wherein the setting bolt is entirely metal.

12. The fastening system according to claim 1 , wherein the setting bolt has an axial dimension and the axial dimension of the sealing element amounts to at least 10% of the axial dimension of the setting bolt before the setting bolt is set.

13. The fastening system according to claim 1 , wherein the setting bolt has an axial dimension and the axial dimension of the sealing element amounts to at least 20% of the axial dimension of the setting bolt before the setting bolt is set.

14. The fastening system according to claim 1 , wherein the setting bolt has an axial dimension and the axial dimension of the sealing element amounts to at least 30% of the axial dimension of the setting bolt before the setting bolt is set.
