  • Patent number: 10023122
    Abstract: A mirror reflective element suitable for use in an exterior rearview mirror assembly of a vehicle includes a glass substrate having a first side and an opposing second side. The mirror reflective element has a principal reflector portion and an auxiliary reflector portion. The auxiliary reflector portion includes a curved recess established at the second side of the glass substrate. An auxiliary mirror metallic reflector is coated at the curved recess at the second side of the glass substrate and a principal mirror metallic reflector is coated at the principal reflector portion. The mirror reflective element is configured so that, when an exterior rearview mirror assembly equipped with the mirror reflective element is normally mounted at a side of a vehicle, the curved recess is disposed at an outboard upper region of the mirror reflective element relative to the side of the equipped vehicle.

  • Patent number: 9102279
    Abstract: A mirror reflector sub-assembly for a vehicular exterior rearview mirror assembly includes a mirror reflective element having a glass substrate. A principal reflector portion has a first radius of curvature and an auxiliary reflector portion includes a curved recess having a second radius of curvature smaller than the first radius of curvature. The curved recess is established at the second surface of the glass substrate by physical removal of glass from a portion of the substrate. The mirror reflective element is supported at a side of a mirror back plate and an opposing side of the mirror back plate is adapted for attaching the mirror back plate to a mirror actuator of an exterior rearview mirror assembly equipped with the mirror reflector sub-assembly. A heater pad is disposed at the second surface of the glass substrate between the mirror reflective element and the mirror back plate.

  • Patent number: 8559093
    Abstract: An electrochromic mirror reflective element suitable for use in a rearview mirror assembly of a vehicle includes first and second substrates having an electrochromic medium disposed therebetween and bounded by a perimeter seal. A perimeter coating is disposed at a second surface of the first substrate proximate at least a perimeter portion of the first substrate. The perimeter coating generally conceals the perimeter seal from view by a person viewing a first surface of the first substrate and through the first substrate. An at least partially reflective stack of thin films is disposed at least a portion of a third surface of the second substrate. The perimeter seal is at least partially visible to a person viewing a fourth surface of the second substrate and through the second substrate.
