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:
a prismatic interior mirror reflective element comprising a glass substrate;
wherein said glass substrate has a front surface and a rear surface opposite said front surface;
wherein a mirror reflector is disposed at said rear surface of said glass substrate of said mirror reflective element and wherein said front surface of said glass substrate is angled relative to said rear surface of said glass substrate forming a prismatic glass substrate;
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 a 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 said rear surface of said glass substrate 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 a plane of 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; 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 front surface of said glass substrate to a less-curved portion at said 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 and said mounting element are formed together.

5. 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.

6. The interior rearview mirror assembly of claim 1 , wherein said mirror reflective element nests in said plastic molding.

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

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

9. The interior rearview mirror assembly of claim 1 , comprising a toggle assembly, wherein said pivot element is configured to pivotally mount said mirror reflective element at a double-ball mounting arm of the mounting structure.

10. The interior rearview mirror assembly of claim 1 , comprising a toggle assembly, wherein said pivot element is configured to pivotally mount said mirror reflective element at a single-ball mounting arm of the mounting structure, and wherein the single-ball mounting arm comprises a ball pivot element with a wiring passageway therethrough.
