Abstract

The invention relates to an assembly for securing a fastening element to a first component, wherein the first component has a passage opening for a shaft of the fastening element, said assembly comprising a securing element, which reaches around the shaft of the fastening element, wherein a head part of the fastening element and the securing element are arranged on opposite sides of the first component and the shaft of the fastening element engages in a receptacle of a second component for the frictional and/or interlocking connection of the two components. According to the invention, the securing element is pre-fastened to the second component before a first connection of the first component to the second component and is separated from the second component and reaches around the shaft of the fastening element after a first release of the connection between the first component and the second component.

First claim

The invention claimed is:

1. An arrangement for securing a fastening element to a first component, wherein the first component has a through-hole for a shaft of the fastening element, said arrangement having a securing element, which reaches around the shaft of the fastening element, wherein a head part of the fastening element and the securing element are arranged on opposite sides of the first component and the shaft of the fastening element engages in a receiving means of a second component for a frictional and/or interlocking connection of the first and second components, wherein the securing element is pre-fixed to the second component before the connection of the first component to the second component and is separated from the second component and reaches around the shaft of the fastening element after an initial release of the connection between the first component and the second component.

2. The arrangement according to claim 1 , wherein the shaft of the fastening element has a barrier for reaching behind the securing element during the connection of the first component to the second component.

3. The arrangement according to claim 2 , wherein the barrier is a barb.

4. The arrangement according to claim 2 , wherein the barrier is a threaded flank increasing in circumference.

5. The arrangement according to claim 1 , wherein the securing element is made from an elastic material.

6. The arrangement according to claim 1 , wherein the securing element is a washer.

7. The arrangement according to claim 1 , wherein the securing element is a cap.

8. The arrangement according to claim 1 , wherein the first component is part of a motor vehicle body.

9. The arrangement according to claim 8 , wherein the second component is an equipment element to be fastened to the motor vehicle body.

10. The arrangement according to claim 9 , wherein the equipment element is a motor vehicle lighting device.

11. A method for securing a fastening element to a first component by means of a securing element which is arrangeable on a shaft of the fastening element so that a head part of the fastening element and the securing element are arranged on opposite sides of the first component, wherein the securing element is pre-fixed to a second component before a connection of the first component to the second component, the shaft of the fastening element reaches behind the securing element with a barrier during the connection of the first and second components and the securing element is separated from the second component and remains on the shaft of the fastening element after an initial release of the first and second components.

12. The method according to claim 11 , wherein the securing element is pre-fixed to the second component by adhesion or clamping.
