Abstract

A fastening element for the installation and retention of an airbag at the body of a vehicle. The fastening device is equipped with an essentially flat first element component for the immediate fastening of the airbag to the body, and a second element component, basically stirrup shaped, for retaining the airbag between the two element components. The first element section and the second element section are combined to form one open and one closed end of the fastening device, with at least one of the two element components equipped with holding devices, providing for a secure pre-installation of the fastening device to the airbag.

Claims

1. Fastening device for the installation and the retaining of an airbag to the vehicle'"'"'s body, with the fastening device equipped with an essentially flat first element component for the immediate fastening of the airbag to the body and a second element component, basically stirrup shaped, for retaining the airbag between the two element components, with first element component and second element component forming an open and a closed end of the fastening device, with the formation of holding devices in at least one of the two element components, which provide for a secure pre-installation of the fastening element to the airbag.

2. Fastening device in accordance with claim 1, wherein the two element components are joined together at the closed end with two attachments forming a joint edge, and shaped essentially similar.

3. Fastening device in accordance with claim 1, wherein the two attachments are shaped basically flat and provided with a through hole through both attachments, with the attachment of the first element component equipped with a guide, protruding from the first fastening device and extending in a level parallel to the first element component, with the guide equipped with a box nut on the side away from the other attachment.

4. Fastening device according to claim 3, wherein the first element component is equipped with a latching guide, extending away from the second element component and the box nut.

5. Fastening device in accordance with claim 3, wherein the first element component is angled at the open end of the fastening device, away from the second element component.

6. Fastening device in accordance with claim 3, wherein the first element component is equipped with two noses, facing the second element section, fitting into two corresponding openings in the second element section after placement of the airbag in the fastening device and the compression of the two element components, which also are bendable for the purpose of keeping the two sections together.

7. Fastening device in accordance with claim 3, wherein the second element component is equipped with a minimum of two noses directed toward the first element component, which will securely lay atop the first element component after the mounting of the airbag to the fastening device and the compression of the two element components.

8. Fastening device in accordance with claim 1 further comprising a latching clamp at the open end, angled, and elongating the first element component, directed away from second element component, and wherein the two attachments of the first and the second element component each are equipped with a section, with the section of attachment of the first element component at a minimum extending to a level parallel to the first element component after the mounting of the fastening device to the body.

9. Fastening device according to claim 8, further comprising a latching guide in a region bordering the respective attachments of the first element component and the second element component, with the two locking guides formed in such manner that they will form a retaining latch for the two element components after the mounting of the airbag to the fastening device and the compression of the two element components.

10. Fastening device in accordance with claim 8, wherein the first element component is equipped with a first latching guide in the region bordering the respective attachment, bent towards the second element component, and that the second section of the element is provided with a second latching guide in the region bordering the respective attachment, extending towards this attachment and an opening for the insertion of the first latching guide with the two locking guides formed in such manner that they will form a joint retaining latch for the two element components after the mounting of the airbag to the fastening device and the compression of the two element components.

11. Fastening device in accordance with claim 8, further comprising an angled blocking guide at the closed end of the first element component, extending beyond the common edge on side away from second element component which will prevent the mounting of a covering for the airbag to the body in the event of improper installation of the fastening device.

12. Fastening device in accordance with claim 1, further comprising longitudinal edges with borders along the second element component, protecting the airbag placed into the fastening device by being free of lines or directed away from the first element component, extending from the open to the closed end of the fastening device.

13. Fastening device in accordance with claim 1, which is produced by punching out sheet metal and folding.

14. Fastening device in accordance with claim 1, which is produced by a plastic spraying method.

15. Fastening device in accordance with claim 1, wherein one of the two element components is manufactured of plastic, and the other component, is manufactured of metal.
