Abstract

An assembly for mounting a sensor to a vehicle includes a base, a sensor bracket, and a tolerance compensator between the base and the sensor bracket. The tolerance compensator is threadedly coupled to the base and releasably engaged with the sensor bracket in an assembled position. The assembly includes a washer including a hub fixed relative to the base and a plurality of tabs arranged circumferentially around the hub and extending radially relative to the hub. One of the tabs is moveable into engagement with the tolerance compensator in the assembled position.

First claim

The invention claimed is:

1. An assembly comprising:
a base;
a sensor bracket;
a tolerance compensator between the base and the sensor bracket, the tolerance compensator being threadedly coupled to the base and releasably engaged with the sensor bracket in an assembled position; and
a washer including a hub fixed relative to the base and a plurality of tabs arranged circumferentially around the hub and extending radially relative to the hub;
one of the tabs being moveable into engagement with the tolerance compensator and the sensor bracket in the assembled position.

2. The assembly of claim 1 , wherein the washer includes an aperture and the base includes an aperture that is coaxial with the aperture of the washer.

3. The assembly of claim 2 , further comprising a connector coaxial with the aperture of the washer, the connector being fixed relative to the base and threadedly engaged with the tolerance compensator.

4. The assembly of claim 3 , wherein the sensor bracket includes an aperture coaxial with the aperture of the washer and the tolerance compensator includes a bore coaxial with the aperture of the washer, and further comprising a fastener extending through the aperture of the sensor bracket and into the bore of the tolerance compensator.

5. The assembly of claim 2 , further comprising a rivet nut extending through the aperture of the washer and the aperture of the base, the rivet nut being riveted to the base and threadedly engaged with the tolerance compensator.

6. The assembly of claim 5 , wherein the base has a front side and a back side, the aperture extending through the front side and the back side, the rivet nut includes a bulb on the back side and a radial flange on the front side, the washer being pinched between the radial flange and the front side.

7. The assembly of claim 6 , wherein the front side, the hub of the washer, and the radial flange are in parallel planes between the front side and the radial flange.

8. The assembly of claim 1 , further comprising a connector being fixed relative to the base and threadedly engaged with the tolerance compensator.

9. The assembly of claim 8 , wherein the washer is between the base and the connector.

10. The assembly of claim 1 , wherein the sensor bracket includes an aperture and the tolerance compensator includes a bore coaxial with the aperture of the sensor bracket, and further comprising a fastener extending through the aperture of the sensor bracket and into the bore of the tolerance compensator.

11. The assembly of claim 10 , wherein the fastener is threadedly engaged with the bore of the tolerance compensator.

12. The assembly of claim 1 , wherein the one of the tabs that is moveable into engagement with the tolerance compensator in the assembled position is moveable independently of the other ones of the tabs.

13. The assembly of claim 1 , wherein the one of the tabs that is moveable into engagement with the tolerance compensator in the assembled position is elongated transverse to the hub in the assembled position and the other ones of the tabs are elongated radially from the hub in the assembled position.

14. A method of installing a sensor bracket to a base, the method comprising:
threadedly coupling a tolerance compensator to the base;
releasably engaging the sensor bracket to the tolerance compensator;
fixing a hub of a washer relative to the base, the washer including a plurality of tabs arranged circumferentially around the hub and extending radially relative to the hub; and
after threadedly coupling the tolerance compensator to the base, moving one of the tabs into engagement with the tolerance compensator and the sensor bracket.

15. The method of claim 14 , wherein releasably engaging the sensor bracket to the tolerance compensator includes inserting a threaded fastener through an aperture of the sensor bracket and threadedly engaging a threaded bore of the tolerance compensator.

16. The method of claim 15 , wherein the fastener engages the bore of the tolerance compensator such that the fastener is free of direct engagement with the base.

17. The method of claim 14 , further comprising coaxially aligning an aperture in the hub, an aperture of the base, and an aperture of the sensor bracket.

18. The method of claim 14 , further comprising inserting a rivet nut into an aperture in the hub of the washer and into an aperture of the base, deforming the rivet nut on a back side of the base, wherein threadedly coupling the tolerance compensator to the base includes threadedly engaging threads of the tolerance compensator with threads of the rivet nut.
