Abstract
Abstract A laminated window includes at least one rigid external substrate (5) and a sheet made of flexible plastic material (6) which is adjacent to the substrate (5). The window is equipped with an electrostatic protection circuit which is capable of dissipating the charges which have accumulated on the external sheet (7). This circuit includes conducting elements (2) which cross through at least the substrate and at least one part of the sheet made of plastic material (6). The conducting elements (2) are connected to a collector element (3) which is connected to the ground (4) and embedded in the sheet made of flexible plastic material (6).

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
99 words
A laminated window comprising: at least one external rigid substrate which is capable of being loaded with electrostatic charges; a sheet of flexible plastic material adjacent to the substrate; and an electrostatic protection circuit which can dissipate the charges which have accumulated on the external sheet, said circuit comprising: a) an electrically grounded collector element embedded in said sheet of flexible plastic material, and b) conductor elements which pass through at least said substrate, wherein said conductor elements pass through at least one part of said sheet of flexible plastic material and are electrically connected to said collector element.
Claim 2
Dependent Claim
99 words
A laminated window comprising: at least one external rigid substrate which is capable of being loaded with electrostatic charges; a sheet of flexible plastic material adjacent to the substrate; and an electrostatic protection circuit which can dissipate the charges which have accumulated on the external sheet, said circuit comprising: a) an electrically grounded collector element embedded in said sheet of flexible plastic material, and b) conductor elements which pass through at least said substrate, wherein said conductor elements pass through at least one part of said sheet of flexible plastic material and are electrically connected to said collector element.
Claim 3
Dependent Claim
27 words
The laminated window according to claim 1, wherein said collector element is not coplanar with an interface between said substrate and said sheet of flexible plastic material.
Claim 4
Dependent Claim
37 words
The laminated window according to claim 1, wherein said conductor elements extend substantially perpendicular to the plane of the window, and wherein said collector element extends in a plane substantially parallel to the plane of the window.
Claim 5
Dependent Claim
18 words

Claim 6
Dependent Claim
20 words
The laminated window according to claim 1, wherein said conductor elements are made of only one conductor wire or filament.
Claim 7
Dependent Claim
39 words
The laminated window according to claim 5, wherein said conductor elements are made of one wire or filament forming a loop near an external side of the external rigid substrate which is capable of being loaded with electrostatic charges.
Claim 8
Dependent Claim
21 words
The laminated window according to claim 6, wherein said conductor elements and said collector element are comprised of the same filament.
Claim 9
Dependent Claim

Claim 12
Dependent Claim
47 words
The laminated window according to claim 9, wherein said heating elements each comprises a conducting layer lying in a plane which is between the external surface of said external rigid substrate which is capable of being loaded with electrostatic charges and the plane of said collector element.
Claim 13
Dependent Claim
22 words
The laminated window according to claim 10, wherein said collector element is connected electrically to said collecting strip of the heating circuit.
Claim 14
Dependent Claim
