ABSTRACT:
A strengthened, reinforced safety mirror especially adapted for use in interior rearview mirror assemblies in vehicles used in varying climates. The safety mirror has increased tensile strength and resistance against bending, breakage, and shattering as well as the ability to retain any glass fragments when broken. The mirror includes a reinforcing sheet means secured with adhering or bonding means to the rear surface of the glass mirror element. The reinforcing sheet means has a coefficient of thermal expansion matched to that of the glass to prevent differential expansion between the glass and the reinforcing sheet thereby assuring a secure bond between the same and preventing distortion of the glass in substantially all temperatures. The density of the reinforcing sheet is also preferably matched to the viscosity of the bonding means to further insure a secure bond and proper strength of the mirror.
