Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
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.
Claim 2
Dependent Claim
122 words
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.
Claim 3
Dependent Claim
30 words
The improved windshield of claim 1 wherein: the conductive coating of the transparent material is spaced inwardly at least one-eighth of an inch from the entire perimeter of the windshield.
Claim 4
Dependent Claim
138 words
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 generally the same size as and adjacent the outer lite; a second laminating interlayer generally the same size as and adjacent the inner lite; and a transparent, electrically conductive material formed by a transparent support layer with an electrically conductive coating on the transparent layer, the electrically conductive coating on the transparent support layer being 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.
Claim 5
Dependent Claim
138 words
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 generally the same size as and adjacent the outer lite; a second laminating interlayer generally the same size as and adjacent the inner lite; and a transparent, electrically conductive material formed by a transparent support layer with an electrically conductive coating on the transparent layer, the electrically conductive coating on the transparent support layer being 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.
Claim 6
Dependent Claim
25 words
The improved windshield of claim 3 wherein: the electrically conductive coating is spaced inwardly at least one-eighth inch from the entire perimeter of the windshield.
Claim 7
Dependent Claim
21 words
The improved windshield of claim 3 wherein: the transparent layer extends to the edges of the first and the second lites.
Claim 8
Dependent Claim
21 words
The improved windshield of claim 3 wheRein: the transparent support layer is the same size as the electrically conductive coating thereon.
Claim 9
Dependent Claim
32 words
The improved windshield of claim 3 wherein: the electrically conductive coating on the transparent support is divided into at least two independent and distinct zones to which electrical connection can be made.
Claim 10
Dependent Claim
57 words
The improved windshield of claim 3 wherein: the electrically conductive coating on the transparent support is divided into at least three independent and distinct zones to which electrical connection can be made, two of the zones having a single power electrical connection and the third zone having a common connection also connected to the other two zones.
