Abstract

A fixing unit for a fastening device to fix a first vehicle component to a second vehicle component is disclosed. The fastening device includes a plate element fixed to a coupling section on an essentially flat surface of the first vehicle component. A threaded stud extends from the plate element and is configured to be arranged in a receptacle of a second vehicle component.

Claims

1. A fixing unit for a fastening device to fix a first vehicle component to a second vehicle component comprising at least one plate element secured by at least one coupling section on a flat surface of the first vehicle component, and at least one stud element extending from the plate element, wherein a receiving region of the stud element is configured to be received in a receptacle of a second vehicle component, wherein the plate element further comprises a depression in which a portion of the stud element is arranged, the depth of the depression selected such that the at least one plate element presses the fixing unit against the flat surface of the first vehicle component.

2. The fixing unit according to claim 1 wherein the at least one plate element is configured to be detachably fixed to the flat surface.

3. The fixing unit according to claim 1 wherein the at list one plate element is configured to be undetachably fixed to the flat surface.

4. The fixing unit according to claim 1, wherein the stud element comprises a male threaded region configured to receive a nut of the fastening device for fixing the first vehicle component and second vehicle component in place.

5. The fixing unit according to claim 1 wherein the stud element comprises a side having an attachment area affixing the stud element to the plate element.

6. The fixing unit according to claim 5, wherein the stud element comprises a transverse segment, and a longitudinal segment having a male threaded region, wherein the transverse segment and the longitudinal segment together define a T-shaped stud element.

7. The fixing unit according to claim 6, wherein the attachment area is formed on a surface of the transverse segment.

8. The fixing unit according to claim 6, wherein the plate element comprises an opening bordered by an edge, wherein the opening receives the longitudinal segment of the stud element, and wherein the edge is abutted by the fastening area of the transverse segment to define a rear engagement.

9. The fixing unit according to claim 6, further comprising a coupling section having at least one lip-shaped projection formed on the plate element.

10. The fixing unit according to claim 9, wherein the coupling section further comprises at least one opening formed therethrough.

11. The fixing unit according to claim 1, further comprising a stamped part configured as the plate element and a bolt configured as the threaded stud.

12. A fastening device for fixing a first vehicle component against a second vehicle component comprising a rear engagement unit having a plate element and a threaded stud extending therefrom, wherein the plate element includes at least one coupling section fixed on a flat surface of a first vehicle component, and wherein a male threaded portion of the threaded stud is received in a receptacle of a second vehicle component, and wherein the plate element further comprises a depression in which a portion of the threaded stud is arranged, the depth of the depression selected such that the at least one plate element presses the stud element against the flat surface of the first vehicle component.

13. A motor vehicle comprising a first vehicle component, a second vehicle component and at least one fastening device according to claim 12.
