Abstract

An interior rearview mirror assembly includes a mirror head and a mounting assembly for adjustably mounting the mirror head at an interior portion of a vehicle. The mounting assembly includes a mounting base that is attachable to an interior portion of the vehicle and a mounting arm adjustably joined to the mounting base via a base joint. The mirror head is pivotally adjustable relative to the mounting arm via a mirror pivot joint. The mounting arm includes an arm portion and a mirror ball portion that are unitarily formed of a metallic material. The mirror ball portion of the mounting arm is pivotally received at a socket element of the mirror head. The mirror head is adjustable about the base and mirror joints to adjust a rearward field of view of a driver of the vehicle when the mirror assembly is normally mounted in the vehicle.

Claims

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

a mirror head having a reflective element;

a mounting assembly for adjustably mounting said mirror head 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 joined to said mounting base via a base pivot joint, and wherein said mirror head is pivotally adjustable relative to said mounting arm via a mirror pivot joint;

wherein said mounting arm comprises an arm portion and mirror ball portion that are unitarily formed of a metallic material;

wherein said mirror ball portion of said mounting arm is pivotally received at a socket element of said mirror head; and

wherein said mirror head and reflective element are adjustable about said base and mirror pivot joints to adjust a rearward field of view of a driver of a vehicle when said mirror assembly is normally mounted in the equipped vehicle.

2. The interior rearview mirror assembly of claim 1, wherein said mounting arm comprises a hollow arm portion that receives a ball member of said mounting base therein to pivotally attach said mounting arm at said mounting base.

3. The interior rearview mirror assembly of claim 1, wherein said mounting arm comprises a base ball portion at an end of said arm portion opposite said mirror ball portion, and wherein said base ball portion, said arm portion and said mirror ball portion are unitarily formed of said metallic material.

4. The interior rearview mirror assembly of claim 1, wherein said mounting arm is formed via a hydroforming process.

5. The interior rearview mirror assembly of claim 1, wherein said mounting arm comprises a computer numerically controlled spun metallic tube.

6. The interior rearview mirror assembly of claim 1, wherein said mounting arm comprises aluminum.

7. The interior rearview mirror assembly of claim 1, wherein said mounting arm comprises steel.

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

a mirror head having a reflective element;

a mounting assembly for adjustably mounting said mirror head 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 joined to said mounting base via a base pivot joint, and wherein said mirror head is pivotally adjustable relative to said mounting arm via a mirror pivot joint;

wherein said mounting arm comprises an arm portion and a mirror ball portion that are unitarily formed of a metallic material;

wherein said mounting arm comprises one of (i) a computer numerically controlled spun metallic tube and (ii) a mounting arm formed via a hydroforming process;

wherein said mounting arm comprises a hollow arm portion that receives a ball member of said mounting base therein to pivotally attach said mounting arm at said mounting base;

wherein said mirror ball portion of said mounting arm is pivotally received at a socket element of said mirror head; and

wherein said mirror head and reflective element are adjustable about said base and mirror pivot joints to adjust a rearward field of view of a driver of a vehicle when said mirror assembly is normally mounted in the equipped vehicle.

9. The interior rearview mirror assembly of claim 8, wherein said mounting arm comprises aluminum.

10. The interior rearview mirror assembly of claim 8, wherein said mounting arm comprises steel.

11. The interior rearview mirror assembly of claim 8, wherein said mounting arm comprises a computer numerically controlled spun metallic tube.

12. The interior rearview mirror assembly of claim 8, wherein said mounting arm is formed via a hydroforming process.

13. A method of forming a mounting arm of a mounting assembly of an interior rearview mirror assembly for a vehicle, said method comprising:

forming a mounting arm comprising an arm portion and a mirror ball portion that are unitarily formed together;

wherein said mounting arm comprises a metallic material; and

wherein said mirror ball portion of said mounting arm is configured to be pivotally received at a socket element of the mirror head, and wherein said mounting arm is configured for pivotally mounting a mirror head at a mounting base that is attachable to an interior portion of a vehicle.

14. The method of claim 13, wherein said mounting arm comprises a hollow tubular arm portion.

15. The method of claim 14, wherein an end of said hollow tubular arm portion is configured to receive a ball member of the mounting base therein to pivotally attach said mounting arm at the mounting base.

16. The method of claim 13, wherein forming a mounting arm comprises forming a mounting arm that comprises a base ball portion at an end of said arm portion opposite said mirror ball portion, and wherein said base ball portion, said arm portion and said mirror ball portion are unitarily formed of said metallic material.

17. The method of claim 13, wherein forming a mounting arm comprises forming a mounting arm via a hydroforming process.

18. The method of claim 13, wherein forming a mounting arm comprises forming a mounting arm via a computer numerically controlled process to form a computer numerically controlled spun metallic tube.

19. The method of claim 13, wherein said mounting arm comprises aluminum.

20. The method of claim 13, wherein said mounting arm comprises steel.
