VEHICLE WINDSHIELD
First Claim
1. In a windshield for a motor vehicle having an outer glass lite and an inner glass lite, wherein the windshield can support between the two glass lites a transparent material having an electrically conductive coating thereon for heating the two glass lites, the improvement comprising:
- a first laminating interlayer adjacent the outer lite;
a second laminating interlayer adjacent the inner lite; and
a transparent material having an electrically conductive coating thereon disposed between the first and the second laminating interlayers, the electrically conductive coating on the transparent material being spaced inwardly from the edges of the first and the second glass lites around the perimeter of the windshield an amount sufficient to permit the windshield to be hermetically sealed during its manufacture.

Abstract
A vehicle windshield is disclosed which is constructed of an inner and an outer glass lite. These lites have first and second laminating interlayers therebetween. A transparent, electrically conductive material is disposed between the first and the second laminating interlayers. The conductive coating on the electrically conductive material is spaced inwardly from the edges of the first and the second glass lites around the entire perimeter of the windshield an amount sufficient to permit the windshield to be hermetically sealed during its manufacture.
