Rearview mirror assembly with rounded front substrate
First Claim
1. A rearview mirror assembly for a vehicle, said rearview mirror assembly comprising:
- a mirror reflective element comprising a first glass substrate and a second glass substrate with an electro-optic medium sandwiched therebetween and bounded by a perimeter seal, wherein said first glass substrate has a first surface and a second surface and wherein said second glass substrate has a third surface and a fourth surface, and wherein said second surface has a transparent electrically conductive coating that opposes and contacts said electro-optic medium and wherein said third surface has an electrically conductive coating that opposes and contacts said electro-optic medium;
a front substrate having a front side and a rear side and a rounded perimeter edge region having a radius of curvature of at least 2.5 mm, wherein said rounded perimeter edge region spans between the front side and rear side along the perimeter of said front substrate;
wherein said front substrate includes a reflective circumferential perimeter band established at said rear side of said front substrate and along a periphery of said rear side of said front substrate;
wherein said rear side of said front substrate is adhesively attached at said first surface of said first glass substrate of said mirror reflective element; and
wherein, when said rear side of said front substrate is adhesively attached at said first surface of said first glass substrate of said mirror reflective element, said reflective circumferential perimeter band conceals said perimeter seal of said mirror reflective element from view to a person viewing said front side of said front substrate.

Abstract
A rearview mirror assembly for a vehicle includes a mirror reflective element having a first glass substrate and a second glass substrate with an electro-optic medium sandwiched therebetween and bounded by a perimeter seal. The first glass substrate has a first surface and a second surface and the second glass substrate has a third surface and a fourth surface. The second surface has a transparent electrically conductive coating that opposes and contacts the electro-optic medium and the third surface has an electrically conductive coating that opposes and contacts the electro-optic medium. A front substrate has a rounded perimeter edge region that has a radius of curvature of at least 2.5 mm and that spans between a front side and a rear side of the front substrate. The rear side of the front substrate is adhesively attached at the first surface of the first glass substrate of the mirror reflective element.

9. A method of assembling a rearview mirror assembly for a vehicle, said method comprising:
-
providing a mirror reflective element comprising a first glass substrate and a second glass substrate with an electro-optic medium sandwiched therebetween and bounded by a perimeter seal, wherein said first glass substrate has a first surface and a second surface and wherein said second glass substrate has a third surface and a fourth surface, and wherein said second surface has a transparent electrically conductive coating that opposes and contacts said electro-optic medium and wherein said third surface has an electrically conductive coating that opposes and contacts said electro-optic medium; providing a front substrate having a front side and a rear side; forming a rounded perimeter edge region along the perimeter of said front substrate, wherein said rounded perimeter edge region spans between the front side and rear side and has a radius of curvature of at least 2.5 mm, wherein said rounded perimeter edge region is formed along the perimeter of said front substrate when said front substrate is separate from said mirror reflective element; establishing a reflective circumferential perimeter band at said rear side of said front substrate and along a periphery of said rear side of said front substrate; after forming said rounded perimeter edge region along the perimeter of said front substrate and after establishing said reflective circumferential perimeter band at said rear side of said front substrate, adhesively attaching said rear side of said front substrate at said first surface of said first glass substrate of said mirror reflective element; and wherein, when said rear side of said front substrate is adhesively attached at said first surface of said first glass substrate of said mirror reflective element, said reflective circumferential perimeter band conceals said perimeter seal of said mirror reflective element from view to a person viewing said front side of said front substrate. - View Dependent Claims (10, 11, 12)
