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 structure that is attachable to an interior portion of the vehicle and includes a mirror mounting element pivotally attached at an end of the mounting structure to establish a mirror ball pivot joint. The attaching portion of the mirror mounting element is configured to attach to a receiving portion of the mirror head via a snap connection and/or a twist connection. The attaching portion of the mirror mounting element, when the mirror mounting element is attached at the end of the mounting structure, is attachable to the receiving portion of the mirror head from a position rearward of the mirror casing and from exterior the mirror casing to attach the mirror head at the mounting structure.

Claims

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

a mirror head comprising a mirror casing and 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 structure that is attachable to an interior portion of the equipped vehicle;

wherein said mounting assembly comprises a mirror mounting element pivotally attached at an end of said mounting structure to establish a mirror ball pivot joint and wherein said end of said mounting structure at which said mirror mounting element is attached is opposite the interior portion of the equipped vehicle when said mounting structure is attached to the interior portion of the equipped vehicle;

wherein said mirror casing comprises a non-circular receiving portion configured to receive a non-circular attaching portion of said mirror mounting element;

wherein said non-circular attaching portion comprises at least one locking tab protruding radially outward therefrom;

wherein said attaching portion of said mirror mounting element is configured to attach to said receiving portion via at least one of (a) a snap connection, (b) a twist connection and (c) a bayonet connection;

wherein said receiving portion of said mirror casing includes at least one stop that, when said attaching portion engages said at least one stop as said attaching portion is inserted into said receiving portion, limits insertion of said attaching portion into said receiving portion of said mirror casing;

wherein, with said attaching portion received in said receiving portion and engaged with said at least one stop, said at least one locking tab engages a locking tab of said mirror casing to limit retraction of said attaching portion from said receiving portion; and

wherein said attaching portion of said mirror mounting element, when said mirror mounting element is attached at said end of said mounting structure, is attachable to said receiving portion of said mirror casing of said mirror head from a position rearward of said mirror casing and from the exterior of said mirror casing to pivotally attach said mirror head at said end of said mounting structure.

2. The interior rearview mirror assembly of claim 1, wherein said mirror mounting element comprises a ball portion and said attaching portion, and wherein said ball portion is pivotally received at said end of said mounting structure.

3. The interior rearview mirror assembly of claim 2, wherein said ball portion is insert molded at said attaching portion.

4. The interior rearview mirror assembly of claim 3, wherein said mounting structure comprises a mounting base attachable to the interior portion of the equipped vehicle and a mounting arm attached at said mounting base, and wherein said end of said mounting structure comprises an end of said mounting arm opposite said mounting base, said end of said mounting arm receiving said ball portion of said mirror mounting element therein to pivotally attach said mirror mounting element at said end of said mounting arm.

5. The interior rearview mirror assembly of claim 4, wherein said mounting arm is pivotally attached at said mounting base to provide a double pivot mounting assembly.

6. The interior rearview mirror assembly of claim 5, wherein said mounting base is attachable to a mirror mounting button adhesively attached at an in-cabin surface of a windshield of the equipped vehicle.

7. The interior rearview mirror assembly of claim 1, wherein said mounting structure comprises a mirror mount attachable to a mirror mounting button adhesively attached at an in-cabin surface of a windshield of the equipped vehicle, and wherein said mirror mounting element is pivotally attached at said end of said mirror mount.

8. The interior rearview mirror assembly of claim 1, wherein said mirror mounting element comprises a ball receiving portion and said attaching portion, and wherein said ball receiving portion of said mirror mounting element pivotally receives a ball member of said end of said mounting structure to pivotally attach said mirror mounting element to said mounting structure.

9. The interior rearview mirror assembly of claim 8, wherein said ball receiving portion and said attaching portion of said mirror mounting element are unitarily molded together in the same molding process.

10. The interior rearview mirror assembly of claim 1, wherein said attaching portion of said mirror mounting element is configured to attach to said receiving portion of said mirror head via a snap connection.

11. The interior rearview mirror assembly of claim 1, wherein said attaching portion of said mirror mounting element is configured to attach to said receiving portion of said mirror head via a twist connection.

12. The interior rearview mirror assembly of claim 11, wherein said twist connection comprises a twist lock connection.

13. The interior rearview mirror assembly of claim 1, wherein said mirror mounting element comprises a passageway therethrough for routing an electrically conductive wire therethrough to electrically connect said electrically conductive wire to circuitry of said mirror head.

14. The interior rearview mirror assembly of claim 1, wherein said mounting structure is attachable to a mirror mounting button adhesively attached at an in-cabin surface of a windshield of the equipped vehicle.

15. The interior rearview mirror assembly of claim 1, wherein said mounting structure comprises a mirror mount attachable to said mounting button.

16. The interior rearview mirror assembly of claim 1, wherein said attaching portion of said mirror mounting element is configured to attach to said receiving portion of said mirror head via a fastenerless connection.

17. The interior rearview mirror assembly of claim 16, wherein said attaching portion of said mirror mounting element is configured to attach to said receiving portion of said mirror head via a twist connection.

18. The interior rearview mirror assembly of claim 17, wherein said twist connection comprises a twist lock connection.

19. The interior rearview mirror assembly of claim 1, wherein said attaching portion comprises at least two locking tabs protruding radially outward from opposite sides of said non-circular attaching portion, and wherein, with said attaching portion received in said receiving portion and engaged with said at least one stop, said at least two locking tab engage respective locking tabs of said mirror casing to limit retraction of said attaching portion from said receiving portion.

20. The interior rearview mirror assembly of claim 19, wherein said receiving portion of said mirror casing includes at least two stops disposed at opposite sides of said receiving portion to limit insertion of said attaching portion into said receiving portion.

21. The interior rearview mirror assembly of claim 20, wherein said stops limit insertion of said attaching portion into said receiving portion such that, when said attaching portion is inserted into said receiving portion and engaged with said stops, said attaching portion is spaced from and not engaged with said reflective element.

22. The interior rearview mirror assembly of claim 21, comprising circuitry established on a circuit board disposed in said mirror casing.

23. The interior rearview mirror assembly of claim 22, wherein said circuit board is disposed in said mirror casing such that said circuit board is remote from said attaching portion when said attaching portion is inserted into said receiving portion.
