Patent ID: 7168818

Claim:
A vehicular rearview mirror system for a motor vehicle having a driver's side and a passenger's side, comprising: a first rearview mirror assembly attached to the driver's side for providing a rearward view along the driver's side to the operator of the vehicle, a first planar reflective element assembly comprising a first planar reflective element, a first base assembly fabricated of a first material having a first modulus of elasticity for attaching the first planar reflective element assembly to the exterior of the vehicle, and a first cantilever arm coupling the first planar reflective element assembly to the first base assembly; a second rearview mirror assembly attached to the passenger's side for providing a rearward view along the passenger's side to the operator of the vehicle, a second non-planar reflective element assembly comprising a second non-planar reflective element, a second base assembly fabricated of a second material having a second modulus of elasticity for attaching the second non-planar reflective element assembly to the exterior of the vehicle, and a second cantilever arm coupling the second non-planar reflective element assembly to the second base assembly; wherein said second modulus of elasticity is substantially less than said first modulus of elasticity; and whereby the natural frequency of said first planar reflective element assembly supported by said first cantilever arm on said first base assembly is substantially less than the natural frequency of said second non-planar reflective element assembly supported by said second cantilever arm on said second base assembly.
