Abstract

A vehicle trim assembly is provided that includes a proximity sensor, a first conductive trim component located near the proximity sensor, a second conductive trim component located near the proximity sensor, and a conductive tower formed on the first conductive trim component and electrically coupled to the second trim component to form a conductive path between the trim components and electrical ground.

First claim

What is claimed is:

1. A vehicle trim assembly comprising:
a proximity sensor;
a first conductive trim component located near the proximity sensor;
a second conductive trim component located near the proximity sensor;
a conductive tower formed on the first conductive trim component and electrically coupled to the second trim component to form a conductive path between the first and the second conductive trim components and electrical ground, wherein the first conductive trim component comprises an inner decorative trim ring and the second conductive trim component comprises an outer decorative trim ring that surrounds the inner decorative trim ring; and
a conductive cup formed on the second conductive trim component, wherein the conductive tower is matingly received in the conductive cup to provide the electrical coupling.

2. The assembly of claim 1 , wherein the inner trim ring substantially surrounds a sensing pad of the proximity sensor.

3. The assembly of claim 1 , wherein the conductive tower comprises a plurality of tapered ribs.

4. The assembly of claim 1 , wherein the proximity sensor comprises a capacitive sensor.

5. The assembly of claim 1 , wherein the proximity sensor is configured as a proximity switch to control a lamp, and wherein the proximity sensor is located on a lens of the lamp and the lens provides a sensing pad.

6. The assembly of claim 1 , wherein the first and the second conductive trim components each comprise chrome.

7. The assembly of claim 6 , wherein the chrome is chrome plating.

8. A vehicle trim assembly comprising:
a proximity sensor proximate a sensing pad;
an inner conductive trim component surrounding the proximity sensor;
an outer conductive trim component surrounding the inner conductive trim component;
a conductive tower connecting the inner conductive trim component to the outer conductive trim component to form a conductive path between the inner and the outer conductive trim components and electrical ground, wherein the conductive tower is formed as part of one of the inner and the outer conductive trim components; and
a conductive cup formed as part of the other of the first and second trim components, wherein the conductive tower connects to the conductive cup to form the conductive path.

9. The assembly of claim 8 , wherein the conductive tower comprises a plurality of tapered ribs.

10. The assembly of claim 8 , wherein the proximity sensor comprises a capacitive sensor.

11. The assembly of claim 8 , wherein the proximity sensor is configured as a proximity switch to control a vehicle lamp.

12. The assembly of claim 11 , wherein the proximity sensor is located on a lens of the lamp and the lens provides the sensing pad.

13. The assembly of claim 8 , wherein each of the inner and the outer conductive trim components comprise chrome.

14. The assembly of claim 13 , wherein the chrome is chrome plating.

15. A vehicle trim assembly comprising:
a proximity sensor proximate a sensing pad;
an inner conductive trim component surrounding the proximity sensor;
an outer conductive trim component surrounding the inner conductive trim component;
a conductive tower formed on the inner conductive trim component; and
a conductive cup formed on the outer conductive trim component and electrically connected to the conductive tower to form a conductive path between the inner and the outer conductive trim components and electrical ground.

16. The assembly of claim 15 , wherein the inner conductive trim component comprises a trim ring that substantially surrounds the sensing pad and the outer conductive trim component surrounds the inner conductive trim component, wherein the conductive tower is snap-fit into the conductive cup.
