1. An exterior sideview mirror assembly suitable for vehicular use, said exterior sideview mirror assembly comprising:

  • a bracket configured for fixedly securing said exterior sideview mirror assembly to a vehicle body side;

    a mirror housing secured to said bracket, said mirror housing defining a primary opening;

    a single mirror backing plate element within said mirror housing and disposed adjacent to said primary opening;

    said single mirror backing plate element movable by an electrically-operable actuator;

    a main plano mirror element fixedly secured to and supported by said single mirror backing plate element and disposed within said primary opening for providing a view rearward of a vehicle equipped with said exterior sideview mirror assembly through a first primary field of view;

    an auxiliary non-plano curved mirror element fixedly secured to and supported by said single mirror backing plate element and disposed adjacent to said main plano mirror element, said auxiliary non-plano curved mirror element defined by a single radius of curvature differing from said main plano mirror element such that said auxiliary non-plano curved mirror element provides a second auxiliary field of view rearward of the vehicle equipped with said exterior sideview mirror assembly;

    wherein said first primary field of view of said main plano mirror element overlaps said second auxiliary field of view of said auxiliary non-plano curved mirror element;

    wherein said single mirror backing plate element comprises a generally rigid polymeric molding able to support said main plano mirror element and said auxiliary non-plano curved mirror element;

    wherein said single mirror backing plate element comprises a generally flat portion for supporting said main plano mirror element and a curved portion for supporting said auxiliary non-plano curved mirror element;

    wherein said curved portion of said single mirror backing plate element for supporting said auxiliary non-plano curved mirror element is angled relative to said generally flat portion of said single mirror backing plate element for supporting said main plano mirror element in a mariner such that, when a driver of a vehicle equipped with said exterior side view mirror assembly aligns the rearward field of view of said main plano mirror element, the rearward field of view of said main plano mirror element is aligned downwardly relative to the vehicle body side to which said exterior side view mirror assembly is attached; and

    wherein said main plano mirror element comprises one of (a) a generally flat glass substrate having a surface coated with a metallic reflector coating and (b) a generally flat polymeric substrate having a thin glass element applied to a surface thereof and with an opposing surface thereof having a reflecting layer applied thereto.
