FRAMELESS INTERIOR REARVIEW MIRROR ASSEMBLY
First Claim
1. An interior rearview mirror assembly for a vehicle, said interior rearview mirror assembly comprising:
- a mirror casing;
a prismatic interior reflective element;
wherein said prismatic interior reflective element comprises a wedge-shaped glass substrate having a first surface and a second surface and a perimeter edge about a periphery of said wedge-shaped glass substrate and extending between the first and second surfaces thereof, said wedge-shaped glass substrate having a mirror reflector established at the second surface thereof, the first surface facing a driver of a vehicle when said interior rearview mirror assembly is normally mounted in a vehicle equipped with said interior rearview mirror assembly;
wherein a front surface of the perimeter edge provides a smooth curved transition at the perimeter edge between a perimeter region of the first surface of said wedge-shaped glass substrate and said mirror casing;
said perimeter region circumscribing said wedge-shaped glass substrate;
wherein the front surface of the perimeter edge is rounded at least by grinding to provide a rounded curved surface disposed between the first surface of said wedge-shaped glass substrate and said mirror casing; and
wherein the radius of curvature of the front surface of the perimeter edge is at least 2.5 mm.

Abstract
An interior rearview mirror assembly for a vehicle includes a mirror casing and a prismatic interior reflective element. The reflective element comprises a wedge-shaped glass substrate having a perimeter edge about a periphery of the glass substrate and extending between first and second surfaces thereof. The glass substrate has a mirror reflector established at the second surface. A front surface of the perimeter edge provides a smooth curved transition at the perimeter edge between a perimeter region of the first surface and the mirror casing. The front surface of the perimeter edge is rounded with a radius of curvature of at least about 2.5 mm. No portion of the mirror casing encompasses the first surface of the glass substrate.

14. An interior rearview mirror assembly for a vehicle, said interior rearview mirror assembly comprising:
-
a mirror casing; a mirror reflective element; wherein said mirror reflective element comprises a glass substrate having a first surface and a second surface and a perimeter edge about a periphery of said glass substrate and extending between the first and second surfaces thereof, wherein the first surface of said glass substrate faces a driver of a vehicle when said interior rearview mirror assembly is normally mounted in a vehicle equipped with said interior rearview mirror assembly; wherein said mirror casing comprises a terminal end region that circumscribes an open end of said mirror casing and terminates at a terminal end edge of said mirror casing; wherein said terminal end region of said mirror casing comprises a rounded end region surface curving between said terminal end edge of said mirror casing and an outer surface of a sidewall of said mirror casing; wherein said rounded end region surface is rounded to provide a rounded curved surface disposed between the first surface of said glass substrate and said outer surface of said sidewall of said mirror casing; wherein the radius of curvature of said rounded end region surface is at least 2.5 mm; and wherein said glass substrate is received at said open end of said mirror casing, and wherein no part of said mirror casing encompasses said first surface of said glass substrate. - View Dependent Claims (15, 16, 17, 18, 19, 20)
