Abstract

To fasten a first component to a second component, a fastening clip has an integral, elongated structure with a first and a second fastening end. The first fastening end comprises an at least one-armed independent latching structure. The second fastening end is formed by a resilient clamp. The first and second latching structure act on an intermediate support structure. To connect the two components, the latching structure is latched in a component opening in a first component, and the second component is fastened between the support structure and a spring loop of the resilient clamp with the assistance of a cutout or a slot that is open on one side.

First claim

The invention claimed is:

1. A fastening clip for fastening a first component to a second component that includes an integral, elongated structure with a first and a second fastening end in which the first fastening end forms an at least one-armed independent latching structure, and the second fastening end forms a resilient clamp that each act on an intermediate support structure, wherein the second fastening end comprises a cross bar on which at least two spring loops are arranged opposite each other as resilient clamp.

2. The fastening clip according to claim 1 in which the clamp comprises at least one closed spring loop that encloses an area.

3. The fastening clip according to claim 2 that, in the interior of the at least one spring loop, has a limiting bar with which compression of the spring loop is limited to a maximum.

4. The fastening clip according to claim 2 wherein the area enclosed by the spring loop is parallel to a longitudinal axis of the fastening clip.

5. The fastening clip according to claim 4 , wherein the limiting bar runs parallel to the longitudinal axis.

6. The fastening clip according to claim 2 with a support structure that is designed similar to a plate and has a sealing structure, at least axially on one side.

7. The fastening clip according to claim 2 with a latching structure that has at least one latching bar arranged at an acute angle relative to the longitudinal axis of the fastening clip and comprises an insertion chamfer and an undercut on a free end relative to a releasing direction of the latching structure.

8. The fastening clip according to claim 7 with a support structure that is designed similar to a plate and has a sealing structure, at least axially on one side, and with a latching structure that can latch a component against the sealing structure.

9. The fastening clip according to claim 1 with a support structure that is designed similar to a plate and has a sealing structure, at least axially on one side.

10. The fastening clip according to claim 1 with a latching structure that has at least one latching bar arranged at an acute angle relative to the longitudinal axis of the fastening clip and comprises an insertion chamfer and an undercut on a free end relative to a releasing direction of the latching structure.

11. The fastening clip according to claim 10 with a support structure that is designed similar to a plate and has a sealing structure, at least axially on one side, and with a latching structure that can latch a component against the sealing structure.

12. A first and a second component that are connected by a fastening clip according to claim 1 .

13. A production method for a fastening clip, having the following steps:
a. Providing an injection mold that dictates a single-part structure for the fastening clip, wherein the fastening clip includes an integral, elongated structure with a first and a second fastening end in which the first fastening end forms an at least one-armed independent latching structure, and the second fastening end forms a resilient clamp that each act on an intermediate support structure, wherein the second fastening end comprises a cross bar on which at least two spring loops are arranged opposite to each other as resilient clamp, and
b. Injection molding the fastening clip from only one plastic.

14. The production method according to claim 13 , with the further step:
fastening a sealing structure to the support structure, or
injection molding the sealing structure in the two-component injection molding method so that the sealing structure is fastened to the support structure.

15. A production method for a fastening clip, having the following steps:
a. Providing a data model that dictates a single-part structure for the fastening clip, wherein the fastening clip includes an integral, elongated structure with a first and a second fastening end in which the first fastening end forms an at least one-armed independent latching structure, and the second fastening end forms a resilient clamp that each act on an intermediate support structure, wherein the second fastening end comprises a cross bar on which at least two spring loops are arranged opposite to each other as resilient clamp, and
b. Generating the fastening clip based on the data model from only one plastic by an additive method.

16. A connecting method for fastening a first component to a second component with a fastening clip that includes an integral, elongated structure with a first and a second fastening end in which the first fastening end forms an at least one-armed independent latching structure, and the second fastening end forms a resilient clamp that each act on an intermediate support structure, wherein the second fastening end comprises a cross bar on which at least two spring loops are arranged opposite to each other as resilient clamp, and wherein the connecting method has the following steps:
a. Latching the fastening clip in a component opening of the first component with the assistance of a latching arm of the latching structure, and
b. Fastening the second component with the assistance of a cutout or a slot open on one side between the support structure and a spring loop of the resilient clamp.

17. The connecting method according to claim 16 , with the further step:
arranging an axial bar in the connection in the cutout.

18. The connecting method according to claim 17 , with the further step:
compressing the spring loop depending on a thickness of the second component.

19. The connecting method according to claim 16 , with the further step:
compressing the spring loop depending on a thickness of the second component.
