US Patent 9205780 Electro-optic rearview mirror assembly for vehicle

An exterior mirror reflective element for a vehicular exterior rearview mirror assembly includes a front glass substrate having a transparent conductive coating established at a second surface thereof and a rear glass substrate having a metallic reflector coating established at a third surface thereof, with an electro-optic medium disposed between the second surface of the front glass substrate and the third surface of the rear glass substrate. An electrically conductive clip is disposed along and bridges a perimeter edge of the rear glass substrate to establish electrically conductive connection to the metallic reflector coating at the third surface of the rear glass substrate. A solder joint is established at the electrically conductive clip, and the solder is decoupled from the metallic reflector coating at the third surface of the rear glass substrate.
