A rear view mirror device for relatively permanent attachment to a transparent support such as an automotive vehicle windshield. The rear view mirror device comprises a housing holding a light reflective member, such as a mirror, permitting a view rearwardly of the device, a pivoted arm extending rearwardly of the housing and a bracket adapted for attachment to the windshield. A bonding layer is located in the bracket and is rigidly adhered thereto. An intermediate member, such as a plastic layer, is incidental the opposite side of the bonding layer. Fracturable pins are integral with the bonding layer and extend into the intermediate member and which fracturable pins have ends which are adapted for attachment to a transparent support such as a windshield. These fracturable pins are constructed such that upon a high shear force applied to the rear view mirrow device and which high shear force is imposed upon the pins, they will fracture, thereby permitting separation of the bracket and from the transparent support. This bracket is also highly effective for relatively permanent attachment of any device to a glass or transparent supporting surface and which must separate therefrom upon application of a high shear force.

A device for relatively permanent attachment of a member to a supporting surface, said device comprising: (a) a plastic plate having at least one relatively flat surface thereon and an opposite surface thereon and a plurality of apertures extending between said surfaces, (b) a bonding layer on said one relatively flat surface of said plastic plate and being rigidly bonded thereo, said bonding layer being formed of a material capable of adhesively bonding to a glass or plastic supporting surface for relatively permanent attachment thereto, (c) a plurality of generally parallel fracturable pins formed of the same material as said bonding layer and being integral therewith, said fracturable pins extending through said apertures in said plastic plate, said pins being generally perpendicular to said bonding layer and communicating with said bonding layer and having first and second ends with first ends at said bonding layer and the second ends at an opposite surface of said plastic plate, and (d) a relatively rigid element forming part of said device, said fracturable pins being constructed so that upon application of a high shear force to said device, said pins will fracture at common ones of the ends thereof permitting separation and dis-attachment of at least said relatively rigid element from said supporting surface, said pins being generally closely spaced to one another and present in an amount and relative spacing so that each of said pins will fracture upon application of said high shear force of a predetermined amount, said relatively rigid element being adapted to operatively retain a member to be relatively permanently attached to said supporting surface and which is separated therefrom when said pins fracture.
