Abstract

A fastening system for fastening in a receptacle of a carrier component includes a fastening element with a guide portion insertable into the receptacle along a direction of insertion, and a clip element which is plugged onto the guide portion and which, to hold the fastening element and clip element in the receptacle, has retaining edges which interact with an inner surface of the receptacle, wherein the guide portion and clip element have interacting latching portions formed in such a way that an axial pulling force to release the fastening element and clip element from the receptacle produces a radially outwardly acting force on the retaining edges of the clip element, wherein the fastening element and the clip element further have interacting stop portions which counteract release of the clip element from the fastening element.

First claim

What is claimed is:

1. A fastening system for fastening in a receptacle of a carrier component, comprising a fastening element with a guide portion which can be inserted into the receptacle along a direction of insertion, and comprising a clip element which is plugged onto the guide portion and which, to hold the fastening element and clip element in the receptacle, has retaining edges which interact with an inner surface of the receptacle, wherein the guide portion and clip element have interacting latching portions by means of which the clip element is held against the guide portion in a latching manner, and wherein the latching portions are formed in such a way that an axial pulling force to release the fastening element and clip element from the receptacle causes the latching portions to interact during axial movement of the fastening element away from the clip element so as to produce a radially outwardly acting force on the retaining edges of the clip element, wherein the fastening element and clip element further have interacting stop portions which counteract release of the clip element from the fastening element and the axial movement of the fastening element away from the clip element occurs prior to engagement of the interacting stop portions.

2. The fastening system as claimed in claim 1 , wherein the latching portions of the guide portion comprise at least two ramp surfaces which are formed on opposite outer surfaces of the guide portion and which each extend obliquely outward as seen in the direction of insertion into the receptacle.

3. The fastening system as claimed in claim 2 , wherein the clip element has at least two clip legs which are connected to one another by a connecting portion, wherein the retaining edges are formed by free ends of the clip legs.

4. The fastening system as claimed in claim 3 , wherein the free ends of the clip legs extend obliquely outward as seen counter to the direction of insertion into the receptacle.

5. The fastening system as claimed in claim 3 , wherein the retaining edges each extend obliquely to a plane which is perpendicular to a longitudinal axis of the guide portion.

6. The fastening system as claimed in claim 3 , wherein the clip legs are each received between two wall portions of the guide portion.

7. The fastening system as claimed in claim 3 , wherein the latching portions of the clip element are formed by at least one ramp portion on each clip leg, wherein the ramp portion of each clip leg is arranged between the free end and the connecting portion and extends obliquely outward as seen in the direction of insertion into the receptacle, wherein the ramp portions of the clip legs interact with the ramp surfaces of the guide portion.

8. The fastening system as claimed in claim 3 , wherein the clip legs of the clip element comprise, as said stop portions, in each case at least one stop projection which extends in a direction toward the connecting portion, and in that the guide portion has at least one stop surface with which the stop projections of the clip legs interact.

9. The fastening system as claimed in claim 8 , wherein the at least one stop surface lies in a plane which is substantially perpendicular to a longitudinal axis of the guide portion.

10. The fastening system as claimed in claim 1 , wherein the clip element is held in an axially movable manner on the guide portion, wherein, upon exertion of an axial pulling force to release the fastening element and clip element from the receptacle, at first the interacting latching portions come into engagement with one another before the interacting stop portions come into engagement with one another.

11. The fastening system as claimed in claim 1 , wherein the fastening element has, adjoining the guide portion, a head portion with a retaining portion for retaining at least one object to be fastened on the carrier component.

12. The fastening system as claimed in claim 1 , wherein the fastening element consists of a plastic, produced preferably in a plastic injection-molding process.

13. The fastening system as claimed in claim 1 , wherein the clip element consists of a metal material, preferably in that the clip element is a metal stamped and bent part.

14. A fastening system for fastening in a receptacle of a carrier component, comprising a fastening element with an elongated guide portion insertable into the receptacle along an insertion direction, a clip element plugged onto the guide portion and having first and second retaining edges for holding the fastening element and clip element in the receptacle by the first and second retaining edges interacting with an inner surface of the receptacle, wherein the guide portion and clip element have interacting latching portions for holding the clip element against the guide portion in a latching manner, and wherein the latching portions are formed such that an axial pulling force, applied to the fastening element in a direction opposite the insertion direction, to release the fastening element and clip element from the receptacle causes axial movement of the fastening element away from to the clip element such that the latching portions of the guide portion and the clip element interact to produce a radially outwardly acting force on the first and second retaining edges of the clip element, wherein the fastening element and clip element further have interacting stop portions which counteract release of the clip element from the fastening element and the axial movement of the fastening element away from the clip element occurs prior to engagement of the interacting stop portions.

15. The fastening system as claimed in claim 14 , wherein the latching portions of the guide portion comprise first and second ramp surfaces formed on opposite outer surface portions of the guide portion, each ramp surface extending obliquely outward as seen in the insertion direction.

16. The fastening system as claimed in claim 15 , wherein the clip element has first and second clip legs connected to one another by a connecting portion, wherein a free end of the first clip leg forms the first retaining edge and a free end of the second clip leg forms the second the retaining edge.

17. The fastening system as claimed in claim 16 , wherein the free end of the first clip leg and the free end of the second clip leg each extend obliquely outward as seen in the direction opposite the insertion direction.
