Abstract

The invention relates to a fastening element (1) for vehicle parts (5), in particular for fastening a heat shield to a bolt shaped fastening means (13) of a vehicle body, preferably an underbody of a motor vehicle, comprising a claw disk (2) and a spring washer (3), held at claws (2.1) of the claw disk, wherein the claw disk (2) comprises an opening (6) and the spring washer (3) can be interlocked with a bolt shaped fastening means (13), wherein the claw disk (2) comprises at least one clip element (8), associated with the opening (6) and oriented away from the spring washer (3), wherein the at least one clip element (8) is configured for insertion through an opening (7) in the vehicle part (5) or in the heat shield, and wherein the at least one clip element (8) comprises an undercut (10) for interlocking the rim portion of the opening (7) of the vehicle part (5) or of the heat shield.

Claims

1. A fastening element for fastening a heat shield to a bolt shaped fastener of a vehicle body,

comprising a claw disk having at least two claws and a spring washer, held by the at least two claws of the claw disk,

wherein the claw disk comprises an opening and the spring washer can be interlocked with the bolt shaped fastener, wherein

the claw disk comprises at least one clip element associated with the opening and oriented away from the spring washer,

wherein the at least one clip element is configured for insertion through a perforation in a vehicle part, or in the heat shield;

wherein the at least one clip element is configured as a completely closed collar having a cylindrical shape and having a diameter, said collar protruding perpendicular to the claw disk and comprising at least one bead formed by an expansion of the diameter of the collar at one location and forming an undercut adjacent to the at least one bead on a side facing towards the spring washer by the expansion of the collar for interlocking with the rim portion of the perforation of the vehicle part or of the heat shield, the undercut being provided completely circumferential at the collar, and

wherein the at least one clip element is extended as a spacer part between the undercut and the free end and the undercut is configured to interlock with the vehicle part or the heat shield without additional instrumentalities when the at least one clip element is pushed into the perforation from one side.

2. The fastening element according to claim 1, wherein the free end of the at least one clip element protrudes relative to a section of the claw disk intended for contacting the vehicle part or the heat shield by a length which is at least twice the thickness of the interlocked rim portion of the vehicle part or of the heat shield.

3. The fastening element according to claim 1, wherein the at least one clip element is configured for insertion through a perforation in a vehicle part and the undercut interlocks with the rim portion of the perforation of the vehicle part and wherein at the free end of the at least one clip element, a contact surface for contacting the vehicle body is provided.

4. The fastening element according to claim 3, wherein

the claw disk comprises a flat section outside of the opening for contacting the vehicle part;

and

the at least one clip element protrudes outward substantially perpendicular to the contact surface.

5. The fastening element according to claim 1, wherein the claw disk is formed from aluminum or from an aluminum material.

6. An assembly comprising a vehicle part comprising at least one perforation and a fastening element interlocked in the at least one perforation for fastening a heat shield to a bolt shaped fastener of a vehicle body, said fastening element comprising a claw disk having at least two claws and a spring washer, held by the at least two claws of the claw disk,

wherein the claw disk comprises an opening and the spring washer can be interlocked with the bolt shaped fastener,

wherein the claw disk comprises at least one clip element associated with the opening and oriented away from the spring washer,

wherein the at least one clip element is configured for insertion through the perforation;

wherein the at least one clip element is configured as a completely closed collar having a cylindrical shape and having a diameter, said collar protruding perpendicular to the claw disk and comprising at least one bead formed by an expansion of the diameter of the collar at one location and forming an undercut adjacent to the at least one bead on a side facing towards the spring washer by the expansion of the collar for interlocking with the rim portion of the perforation, the undercut being provided completely circumferential at the collar; and

wherein the at least one clip element is extended as a spacer part between the undercut and the free end and the undercut is configured to interlock with the vehicle part or the heat shield without additional instrumentalities when the at least one clip element is pushed into the perforation from one side.
