Vehicular exterior rearview mirror assembly with a mirror reflective element assembly having a main reflective element and an auxiliary wide angle reflective element

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

• a mirror reflective element assembly;
• wherein the mirror reflective element assembly comprises a main reflective element backing plate;
• wherein the main reflective element backing plate comprises a polymeric substrate;
• wherein a portion of the main reflective element backing plate is flat;
• wherein the mirror reflective element assembly comprises a main reflective element;
• the main reflective element comprising a mirror reflector-coated flat glass substrate, wherein the mirror reflector-coated flat glass substrate of the main reflective element is adhered at the flat portion of the main reflective element backing plate;
• wherein the mirror reflective element assembly comprises an auxiliary reflective element backing plate;
• wherein the auxiliary reflective element backing plate comprises a polymeric substrate;
• wherein the mirror reflective element assembly comprises an auxiliary wide angle reflective element comprising a mirror reflector-coated glass substrate having a curved surface;
• wherein the auxiliary wide angle reflective element is received at a receiving portion of the main reflective element backing plate, and wherein a lip extending from the main reflective element backing plate at least partially circumscribes the auxiliary wide angle reflective element at the receiving portion;
• wherein one or more flexible tabs protrude from the lip and at least partially toward the receiving portion, and wherein, with the auxiliary wide angle reflective element received at the receiving portion of the main reflective element backing plate, the one or more flexible tabs overlap a rear side of the auxiliary wide angle reflective element to secure the auxiliary wide angle reflective element at the receiving portion;
• wherein the main reflective element comprises a cutaway region, and wherein, with the auxiliary wide angle reflective element received at the receiving portion of the main reflective element backing plate, the auxiliary wide angle reflective element is disposed at the cutaway region of the main reflective element;
• and
• wherein the auxiliary reflective element backing plate is attached at the auxiliary wide angle reflective element and to the main reflective element backing plate via an attachment mechanism.
