Abstract:
1. A mirror reflective element assembly for an exterior rearview mirror assembly of a vehicle, said mirror reflective element assembly comprising: a reflective element comprising a glass mirror substrate, said reflective element having a front surface and a rear surface and a first reflector portion and a second reflector portion, said first reflector portion having a first reflective coating disposed thereat; an auxiliary wide angle element disposed at said rear surface of said glass mirror substrate and at said second reflector portion, said auxiliary wide angle element comprising a glass element having a curved rear surface with a second reflective coating disposed at said curved rear surface; an optical coupling element disposed between a front surface of said auxiliary wide angle element and said rear surface of said reflective element, said optical coupling element comprising a substantially optically clear and flexible elastomer; a back plate attached at said rear surface of said reflective element, said back plate having a receiving portion generally at said second reflector portion when said back plate is attached to said reflective element, said auxiliary wide angle element being at least partially received in said receiving portion of said back plate; wherein said back plate comprises at least one sealing element around a perimeter region of said receiving portion, and wherein said at least one sealing element comprises a flexible sealing lip; and wherein said at least one sealing element flexes as it engages said rear surface of said mirror substrate during attachment of said back plate to said reflective element and wherein said at least one sealing element engages and substantially seals against said rear surface of said mirror substrate when said back plate is attached to said reflective element to contain said optical coupling element between said front surface of said auxiliary wide angle element and said rear surface of said reflective element and to limit intrusion of said optical coupling element between said back plate and said mirror substrate.
