Abstract:
1. A method of embedding rigid elements in a windshield, comprising: cutting two sheets of glass in a desired shape to serve as an upper layer and lower layer of the windshield; inserting a layer of interlayer material for each of the two layers of glass, facing each other, between the two layers of glass; placing the rigid elements between the two layers of interlayer material; wherein the rigid elements have a footprint that is smaller than the size of the sheets of glass; pushing the two layers of glass together to form to glass sandwich with the rigid elements and two layers of interlayer material between the upper and lower glass layers; heating the glass sandwich while applying pressure to form a unified sheet of glass, so that the rigid elements settle into the interlayer material displacing some of the interlayer material; and wherein the combined thickness of the layers of interlayer material is at least as thick as the rigid elements, so that when the rigid elements settle into the interlayer material the surrounding interlayer material protects the glass from being damaged by the rigid elements.
