Abstract

A motor vehicle glazing prepared for bonding with the window frame of a motor vehicle body is provided with a profile bead and a single tear-away cord. The profile bead serves as an intermediate body between the glazing surface and an assembly adhesive. In the area coming in contact with the assembly adhesive the width of the profile bead is selected to inhibit the lateral overflow of the assembly adhesive over the profile bead during installation. A tear-away cord is placed inside the profile bead or in its immediate vicinity to shear through the profile bead when removing glazing. The profile bead itself or the adhesive bonding of the profile bead to the glazing surface is shaped so that the width of the section of profile bead to be sheared through by the tear-away cord is substantially smaller than the width of the area coming in contact with the assembly adhesive.
