Abstract
A vehicular exterior sideview mirror assembly includes a main plano mirror element fixedly disposed at a first portion of a mirror backing plate element and an auxiliary non-plano curved mirror element fixedly disposed at a second portion of the backing plate element. The main plano mirror element and the auxiliary non-plano curved mirror element are adjacently disposed at the backing plate element in a side-by-side relationship. The field of view of the main plano mirror element overlaps the field of view of the non-plano curved mirror element. The overall rearward field of view of the main plano mirror element and auxiliary non-plano curved mirror element is at least about 25 degrees relative to the side of the vehicle. The overall rearward field of view of the main plano mirror element and auxiliary non-plano curved mirror element is less than about 50 degrees relative to the side of the vehicle.
