Abstract

A rear-view side mirror assembly includes a base for attachment to a vehicle, one or more support arms extending from the base, and a rearview housing attached to the support arm and configured for telescoping movement along the support arm. A camera is attached within the housing. In some cases, the camera is attached to the support arms so as to remain stationary relative to the mirror base and vehicle as the mirror head telescopes inward and outward. An elongated aperture in the mirror head housing ensures that the camera lens is not occluded as the mirror head telescopes between a retracted position and an extended position.

First claim

What is claimed is:

1. A side-location rearview assembly comprising:
one or more support arms attached to and extending from a base assembly configured for attachment to a side portion of a vehicle;
a rearview housing slidingly attached to the one or more support arms such that the housing can telescope relative to the base between a retracted, inboard position and an extended, outboard position; and
a camera positioned within the housing and attached to the one or more support arms, the camera configured to provide images exterior to the vehicle through an elongated aperture in the housing, wherein the camera is configured to remain in a stationary position relative to the base as the housing telescopes, and wherein the elongated aperture is configured such that the camera can obtain images exterior to the vehicle through the elongated aperture when the housing is in an inboard position and when the housing is in an outboard position; and
further comprising a flexible track attached to the camera and configured to cover a portion of the elongated aperture adjacent the camera regardless of the inboard or outboard position of the housing, the flexible track forming a continuous band within the housing and a track guide assembly having track guides that retain the flexible track in a loop within the housing, the track guide assembly further including a pair of roller drums that support the flexible track in a loop within the housing.

2. The rearview assembly of claim 1 , wherein the aperture has a rectangular cross-sectional shape.

3. The rearview assembly of claim 1 , wherein the flexible track is guided by opposing track guides.

4. The rearview assembly of claim 1 , wherein the roller drums are rotatably journaled in side extensions of the track guide assembly.

5. The rearview assembly of claim 1 , wherein the roller drums have a reduced diameter central portion for accommodating a width of the flexible track, and larger diameter end portions that provide shoulders to retain the flexible track on the roller drum.

6. The rearview assembly of claim 1 , wherein the flexible track includes transverse ridges to increase frictional engagement with the roller drums.

7. A method for attaching a camera to a support structure within a rearview housing that optionally may telescope on telescoping support arms between a retracted, inboard position and an extended, outboard position relative to a base assembly, the method comprising:
providing a camera in a camera holder, the camera holder having at least a pair of opposing snap nibs; and
attaching the opposing snap nibs into corresponding receiving apertures in a support structure within the telescoping rearview housing, the support structure comprising a support arm attached to and extending from the base assembly and relative to which the rearview housing telescopes, whereby the camera remains stationary relative to the base assembly as the rearview housing telescopes relative to the base assembly.

8. The method of claim 7 wherein the camera holder comprises a pair of attachment arms each having a snap nib, the snap nibs opposing one another.

9. The method of claim 8 wherein the opposing snap nibs are elongated and fit into elongated apertures in the support arm.

10. The method of claim 7 wherein the support structure comprises ribs or flanges formed in or fastened to the rearview housing, whereby the camera remains stationary relative to the rearview housing and telescopes with the housing relative to the base assembly.

11. The method of claim 10 wherein the opposing snap nibs are elongated and fit into elongated apertures in the rearview housing.

12. The method of claim 7 wherein the support structure comprises a telescoping arm that cooperates with a support arm attached to and extending from the base assembly and relative to which the rearview housing telescopes, whereby the camera remains stationary relative to the rearview housing and telescopes with the housing relative to the base assembly.

13. A side-location rearview assembly comprising:
one or more support arms attached to and extending from a base assembly configured for attachment to a side portion of a vehicle;
a rearview housing attached to the one or more support arms; and
a camera positioned within the housing and attached to a support structure within the housing, the camera configured to provide images exterior to the vehicle said images obtained through an aperture in the housing; wherein the camera is disposed in a camera holder, the camera holder having at least a pair of attachment arms each having a snap nib opposing the other snap nib and configured to correspond with receiving apertures in the support structure within the rearview mirror housing.

14. The rearview assembly of claim 13 , wherein the support structures within the rearview housing are the support arms extending from the base.
