1. A mirror assembly for use in a vehicle interior comprising:
- a frangible glass mirror having a reflective rear surface;
a stiff planar backing member having a shape to substantially cover the rear surface of said mirror; and
an elastomeric adhesive bonding said backing member to said rear surface of said mirror, said adhesive being selected to be sufficiently elastic, glass retentive, and thick to provide limited and controlled flexing of said mirror when subjected to flexing forces, and when subjected to forces sufficient to break said mirror the resulting shards of glass will be securely held by said adhesive without exceeding a 0.010 inch step between adjacent mirror shards.

Abstract
A shatter resistant mirror includes a frangible mirror material for reflecting an image which has a coating of an elastic adhesive material which bonds a rigid backing material to the frangible mirror body. In a preferred embodiment of the invention, the adhesive was one of a water-based synthetic polymeric material or a hot melt pressure sensitive adhesive. The rigid support member preferably is a fiberboard material. In some embodiments of the invention, the composite mirror structure includes multiple layers of composite fiberboard material to provide spacing for mounting the mirror in a particular application.

20. A vehicle accessory including a composite shatter resistant mirror comprising:
-
an accessory body for mounting within a vehicle, said body including means for mounting a mirror thereto; a frangible mirror including an outwardly facing front surface and a rear surface; a planar stiffening member shaped to cover a substantial portion of the rear surface of said mirror, said stiffening member having a thickness of from about 0.040 inches to about 0.100 inches; and an elastomeric adhesive bonding said stiffening member to said rear surface of said mirror, said adhesive having a thickness of about from 0.004 inches to about 0.010 inches; and said adhesive being selected to be sufficiently elastic and glass retentive to provide limited and controlled flexing of said mirror when subjected to flexing forces and, when subjected to forces sufficient to break said mirror, the resultant shards of glass will be securely held by said adhesive without exceeding a 0.010 inch step between adjacent mirror shards. - View Dependent Claims (21, 22, 23, 24, 25)
