Claim Text:
1. A vehicular exterior rearview mirror system, said vehicular exterior rearview mirror system comprising: an exterior rearview mirror assembly; said exterior rearview mirror assembly comprising a mounting portion adapted for mounting at a side of a vehicle; said exterior rearview mirror assembly comprising a mirror casing portion; a mirror actuator disposed in said mirror casing portion; a mirror reflective element sub-assembly comprising a mirror reflective element; wherein said mirror reflective element sub-assembly is attached to said mirror actuator whereby, in a vehicle equipped with said exterior rearview mirror assembly, the rearward field of view of said mirror reflective element can be adjusted by a driver of the equipped vehicle; said mirror reflective element sub-assembly comprising a mirror back plate, wherein said mirror back plate comprises a plastic molding formed by injection molding; wherein said mirror back plate comprises a first side and an opposing second side; wherein said mirror back plate comprises an actuator mounting portion disposed at said first side for attaching said mirror reflective element sub-assembly to said mirror actuator; wherein a heater pad is disposed between said second side of said mirror back plate and said mirror reflective element; wherein said mirror reflective element is fixedly attached to said mirror back plate with said heater pad disposed therebetween; said mirror reflective element sub-assembly comprising a display indicator having a light source that is activatable to emit light; wherein said light source comprises at least one light emitting diode; wherein said display indicator comprises structure formed during injection molding of said back plate, and wherein said structure extends rearward of said first side of said back plate; wherein said display indicator comprises a light-transmitting passageway that passes through said back plate via an opening therethrough that extends from said first side of said back plate to said second side of said back plate; wherein said light source of said display indicator is mounted rearward of said first side of said back plate; wherein said mirror back plate, said display indicator and said mirror reflective element adjust in tandem when the driver of the equipped vehicle adjusts the rearward field of view of said mirror reflective element via actuation of said mirror actuator to which said mirror reflective element sub-assembly is attached; wherein, when activated, said light source emits light that transmits through said light-transmitting passageway and through a light-transmitting portion of said heater pad and through said mirror reflective element and exits said mirror reflective element at an angle canted towards the side of the equipped vehicle to which said exterior rearview mirror assembly is mounted to be viewable by the driver of the equipped vehicle when said exterior rearview mirror assembly is mounted at the side of the equipped vehicle; wherein said display indicator is associated with a blind spot detection system of the equipped vehicle and wherein said light source of said display indicator is activated responsive to sensing by a sensor of said blind spot detection system of an object in a blind spot at the side of the equipped vehicle at which said exterior rearview mirror assembly is mounted; and wherein said display indicator comprises a substantially water impervious module.
