Abstract

A vehicular interior rearview mirror assembly includes a mirror reflective element having a glass substrate with a planar front surface and a circumferential edge along the periphery of the glass substrate. A mounting element is disposed at the rear of the mirror reflective element and includes a pivot element that is configured to pivotally mount the mirror reflective element at the vehicle. A plastic molding receives the mirror reflective element therein such that a portion of the plastic molding is circumferentially disposed about the circumferential edge of the glass substrate without overlapping onto the front surface of the glass substrate. The portion of the plastic molding provides a curved rounded transition from the front surface of the glass substrate to a side surface of the plastic molding. The plastic molding includes at least a portion of a mirror housing of the interior rearview mirror assembly.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. An interior rearview mirror assembly for a vehicle, said interior rearview mirror assembly comprising:
an electro-optic mirror reflective element comprising a front glass substrate and a rear glass substrate with an electro-optic medium disposed therebetween;
wherein said front glass substrate has a first surface and a second surface opposite said first surface, and wherein a transparent electrically conductive coating is disposed at said second surface and contacts said electro-optic medium;
wherein said rear glass substrate has a third surface and a fourth surface opposite said third surface, and wherein an electrically conductive coating is disposed at said third surface and contacts said electro-optic medium, and wherein said electrically conductive coating includes an electrically conductive reflector coating;
wherein said first surface of said front glass substrate comprises an outermost surface of said electro-optic mirror reflective element that is viewed by a driver of a vehicle equipped with said interior rearview mirror assembly;
wherein said first surface comprises a planar surface and wherein said front glass substrate comprises a circumferential edge along the periphery of said front glass substrate;
wherein said circumferential edge spans a thickness of said front glass substrate between said first surface and said second surface;
a mounting element disposed at said fourth surface of said rear glass substrate of said electro-optic mirror reflective element;
wherein said mounting element includes a pivot element that is configured to pivotally mount said electro-optic mirror reflective element at a mounting structure disposed at an interior portion of the equipped vehicle;
a plastic molding that receives said electro-optic mirror reflective element therein such that a portion of said plastic molding is circumferentially disposed about said circumferential edge of said front glass substrate without overlapping onto said first surface of said front glass substrate;
wherein said first surface of said front glass substrate is flush with an outermost part of said portion of said plastic molding;
wherein said portion of said plastic molding provides a curved rounded transition from said first surface of said front glass substrate of said electro-optic mirror reflective element to a side surface of said plastic molding; and
wherein said plastic molding comprises at least a portion of a mirror housing of said interior rearview mirror assembly.

2. The interior rearview mirror assembly of claim 1 , wherein said portion of said plastic molding curves from adjacent to said first surface of said front glass substrate to a less-curved side surface of said plastic molding.

3. The interior rearview mirror assembly of claim 1 , wherein said plastic molding comprises a soft touch material.

4. The interior rearview mirror assembly of claim 1 , wherein said plastic molding comprises a first plastic material and said mounting element comprises a second plastic material, and wherein said first plastic material is different from said second plastic material.

5. The interior rearview mirror assembly of claim 1 , wherein said plastic molding and said mounting element are formed together.

6. The interior rearview mirror assembly of claim 1 , wherein said plastic molding comprises structure for attaching a mirror housing cap portion thereat, and wherein, with said mirror housing cap portion attached at said structure, said mirror housing cap portion at least partially encases said mounting element.

7. The interior rearview mirror assembly of claim 1 , wherein said electro-optic mirror reflective element nests in said plastic molding.

8. The interior rearview mirror assembly of claim 1 , wherein said portion of said plastic molding contacts said circumferential edge of said front glass substrate.

9. The interior rearview mirror assembly of claim 8 , wherein said rear glass substrate comprises a circumferential edge along the periphery of said rear glass substrate, and wherein said portion of said plastic molding contacts said circumferential edge of said rear glass substrate.

10. The interior rearview mirror assembly of claim 1 , wherein said interior rearview mirror assembly houses a visual indicator that, when actuated to emit visible light, is viewable by the driver of the equipped vehicle.

11. The interior rearview mirror assembly of claim 1 , comprising a plurality of individual indicating elements that, when individually actuated, visually indicate through said electro-optic mirror reflective element to be viewed by the driver of the equipped vehicle, and wherein each of said plurality of individual indicating elements is spaced from and local to another of said plurality of individual indicating elements, and wherein said plurality of individual indicating elements comprises at least three individual indicating elements that are linearly disposed to form a row of individual indicating elements at said electro-optic mirror reflective element.

12. The interior rearview mirror assembly of claim 1 , wherein said plastic molding has a durometer value less than about 110 Shore A.

13. An interior rearview mirror assembly for a vehicle, said interior rearview mirror assembly comprising:
a mirror reflective element comprising a glass substrate;
wherein said glass substrate has a front surface and a rear surface opposite said front surface;
wherein said mirror reflective element comprises a mirror reflector;
wherein said front surface of said glass substrate comprises an outermost surface of said mirror reflective element that is viewed by a driver of a vehicle equipped with said interior rearview mirror assembly;
wherein said front surface of said glass substrate comprises a planar surface and wherein said glass substrate comprises a circumferential edge along the periphery of said glass substrate;
wherein said circumferential edge spans a thickness of said glass substrate between said front surface and said rear surface;
a mounting element disposed at the rear of said mirror reflective element;
wherein said mounting element includes a pivot element that is configured to pivotally mount said mirror reflective element at a mounting structure disposed at an interior portion of the equipped vehicle;
a plastic molding that receives said mirror reflective element therein such that a portion of said plastic molding is circumferentially disposed about said circumferential edge of said glass substrate without overlapping onto said front surface of said glass substrate;
wherein said front surface of said glass substrate is flush with an outermost part of said portion of said plastic molding;
wherein said portion of said plastic molding provides a curved rounded transition from said front surface of said glass substrate of said mirror reflective element to a side surface of said plastic molding;
wherein said mirror reflective element nests in said plastic molding;
wherein said portion of said plastic molding curves from adjacent to said front surface of said glass substrate to a less-curved side surface of said plastic molding;
wherein said plastic molding comprises at least a portion of a mirror housing of said interior rearview mirror assembly; and
wherein said plastic molding comprises structure for attaching a mirror housing cap portion thereat, and wherein, with said mirror housing cap portion attached at said structure, said mirror housing cap portion at least partially encases said mounting element.
