Abstract

An interior rearview mirror assembly includes a mirror casing, a reflective element and a mounting assembly for adjustably mounting the mirror assembly at an interior portion of a vehicle. The mounting assembly has a mounting base and a mounting arm adjustably mounted to the mounting base via a base joint. The reflective element is pivotally adjustable relative to the mounting arm via a mirror pivot joint. The base joint allows for adjustment of the mounting arm in generally a single plane and about a generally horizontal pivot axis when the mirror assembly is normally mounted in the vehicle, with the base joint limiting adjustment of the mounting arm about non-generally horizontal pivot axes. The mirror pivot joint allows for pivotal adjustment of a rearward field of view of the reflective element by a driver of the vehicle when the mirror assembly is normally mounted in the vehicle.

The interior rearview mirror assembly of claim 1, wherein said mounting arm comprises an arm portion and a cylindrical portion at a base end of said arm portion, and wherein said cylindrical portion engages a portion of said mounting base to allow pivotal adjustment of said mounting arm about said generally horizontal pivot axis while limiting pivotal adjustment of said mounting arm about non-generally horizontal axes.

4. The interior rearview mirror assembly of claim 3, wherein said mounting base comprises a clamping element that urges said cylindrical portion of said mounting arm towards said portion of said mounting base to limit pivotal movement of said mounting arm about said generally horizontal pivot axis.

5. The interior rearview mirror assembly of claim 4, wherein said cylindrical portion comprises at least one retaining element and said portion of said mounting arm comprises at least one retaining element, and wherein said retaining elements engage one another and retain said mounting arm in a selected orientation relative to said mounting base.

6. The interior rearview mirror assembly of claim 1, wherein said mirror pivot joint comprises a ball and socket joint and allows for pivotal adjustment of said mirror casing relative to the mounting arm in both vertical and horizontal directions to adjust the rearward field of view of the reflective element when said mirror assembly is normally mounted in the equipped vehicle.

7. The interior rearview mirror assembly of claim 1, wherein a base end of said mounting arm is disposed at least one arcuate arm of said mounting base and is adjustable relative to said arm to adjust said mounting arm in generally a vertical plane and about a generally horizontal pivot axis when said mirror assembly is normally mounted in the equipped vehicle.

8. The interior rearview mirror assembly of claim 1, wherein said mounting assembly supports an accessory and wherein said accessory is adjusted to a selected orientation when said mounting arm is adjusted via said base joint to a selected orientation relative to the windshield of the equipped vehicle when said mounting assembly is attached to an interior portion of the windshield of the equipped vehicle.

9. The interior rearview mirror assembly of claim 1, wherein said mounting assembly supports a forward facing camera that has a forward field of view through the windshield when said mounting assembly is attached to an interior portion of the windshield of the equipped vehicle.

10. The interior rearview mirror assembly of claim 9, wherein said forward facing camera is adjusted in tandem with said mounting arm when said mounting arm is adjusted relative to said mounting base.

11. The interior rearview mirror assembly of claim 9, wherein said base portion includes a shield element and wherein said forward facing camera is disposed at said shield element and with a forward field of view through said shield element, and wherein said forward field of view of said camera is adjustable relative to the windshield when said interior rearview mirror assembly is normally mounted in the equipped vehicle.

12. The interior rearview mirror assembly of claim 11, wherein said forward facing camera and said shield element are adjusted in tandem with said mounting arm so that said mounting arm and said camera are adapted for the particular angle of the windshield to which said mirror assembly is mounted.

13. The interior rearview minor assembly of claim 12, wherein said mounting assembly is adjusted to set said camera relative to the windshield such that said forward facing camera has one of (a) a generally horizontal forward field of view through the windshield when said mirror assembly is normally mounted at the equipped vehicle or (b) a slightly downwardly angled or upwardly angled field of view through the windshield when said mirror assembly is normally mounted at the equipped vehicle.

14. An interior rearview mirror assembly for a vehicle, said interior rearview mirror assembly comprising:

a mirror casing and a reflective element, wherein said reflective element comprises one of a prismatic reflective element and an electrochromic reflective element;

a mounting assembly for adjustably mounting said mirror casing at an interior portion of a vehicle that is equipped with said mirror assembly;

wherein said mounting assembly comprises a mounting base that is attachable to an interior portion of the equipped vehicle and a mounting arm adjustably mounted to said mounting base via a base joint, and wherein said mirror casing is pivotally adjustable relative to said mounting arm via a mirror pivot joint;

wherein said base joint allows for at least one of (a) adjustment of said mounting arm in a generally vertical plane when said mirror assembly is normally mounted in the equipped vehicle and (b) adjustment of said mounting arm about a generally horizontal pivot axis when said mirror assembly is normally mounted in the equipped vehicle;

wherein said base joint substantially limits adjustment of said mounting arm in non-generally vertical planes and about non-generally horizontal pivot axes;
