Exterior rearview mirror assembly

A vehicular exterior rearview mirror assembly, the vehicular exterior rearview mirror assembly comprising:

• a base portion and a mirror head;
• wherein the base portion is configured for attachment at an exterior portion of a vehicle equipped with the vehicular exterior rearview mirror assembly to mount the vehicular exterior rearview mirror assembly at the equipped vehicle;
• wherein the mirror head comprises a mirror reflective element;
• wherein the mirror reflective element comprises a front side and a rear side separated by a thickness dimension of the mirror reflective element;
• wherein, with the base portion attached at the exterior portion of the equipped vehicle, the front side of the mirror reflective element is viewable by a driver of the equipped vehicle when the driver is operating the equipped vehicle;
• wherein the mirror head comprises a mirror back plate having a front side and a rear side separated by a thickness dimension of the mirror back plate;
• wherein the rear side of the mirror reflective element is adhesively attached at the front side of the mirror back plate;
• wherein the mirror back plate includes a perimeter lip that circumscribes a perimeter edge of the mirror reflective element, and wherein no part of the perimeter lip overlaps or extends over any part of the front side of the mirror reflective element, and wherein the perimeter lip of the mirror back plate provides a curved transition between the front side of the mirror reflective element and an outer surface of the mirror head;
• wherein the base portion extends through an aperture in the mirror head;
• a mirror actuator within the mirror head, wherein the mirror actuator, when electrically operated, adjusts the mirror head relative to the base portion;
• wherein, when the mirror actuator is electrically operated, the mirror actuator moves the mirror head and the mirror reflective element together and in tandem relative to the base portion;
• wherein the aperture allows for movement of the mirror head relative to the base portion during operation of the mirror actuator;
• wherein the mirror head comprises a head mounting plate having a front side and a rear side separated by a thickness dimension of the head mounting plate;
• wherein the rear side of the head mounting plate is attached at the mirror actuator;
• wherein the rear side of the mirror back plate is detachably attached at the front side of the head mounting plate;
• wherein the mirror head includes a service recess at and between the mirror back plate and the head mounting plate, wherein the service recess is accessible from exterior the mirror head;
• wherein at least part of the service recess is at least one selected from the group consisting of (i) formed at the rear side of the mirror back plate and (ii) formed at the front side of the head mounting plate;
• and
• wherein the service recess is configured to enable detachment of the mirror back plate, with the mirror reflective element adhesively attached thereto, from the head mounting plate.
