Textile laminate structures including conductive elements and method for making such structures
First Claim
1. An electrically conductive laminate for heating or warming, comprising:
- first and second substantially electrically insulating material sheets adhered to one another on confronting surfaces,first and second electrical conductor means provided between the confronting surfaces of the sheets, anda plurality of patterns on a portion of the confronting surface of the first sheet, wherein said patterns are arranged serially and coextensively with the electrical conductor means so as to have a plurality of regions of intersection between the patterns and the electrical conductor means, wherein the patterns are selected to provide electrical conductivity, wherein a portion of at least one of said patterns electrically contacts the conductor means at regions of intersection, and wherein at least one region of intersection further comprises a means to selectively interrupt the electrical contact of at least one of the electrical conductor means.

Abstract
The invention provides a laminate construction for heating or warming with one or more electrically conductive patterns of conductive ink or paste formed on a first confronting surface of an insulating sheet, where each pattern is connected by one or more conductive elements (bus wires), and where each pattern and the conductive elements are between the confronting surfaces of insulating sheets. The laminate may include one or more stretch and recovery elements to cause the laminate to be more adaptable for securing about any three dimensional body. The laminate with heating elements therein may be incorporated into garments or other wearables or into warming textile structures (pads and blankets).

9. A method for making an electrically conductive laminate comprising:
-
providing a first sheet of a substantially electrically insulating material, forming image-wise on a surface of the first sheet one or more patterns using an electrically conductive ink or paste, coextending at least one length of electrically conductive wire with the first sheet and aligning at least a portion of the conductive wire to intersect at least a portion of the pattern(s) to form an electrically conductive region of intersection between wire and pattern, providing a second sheet of a substantially electrically insulating material, securing a confronting surface of said second sheet to a confronting surface of said first sheet by providing adhesive means between the confronting surfaces, wherein the pattern(s) and the conductive wire and the sheets form the laminate when the confronting surfaces are secured and the pattern(s) and conductive wire are within said laminate, and forming at least one void through the laminate that extends along a substantially vertically aligned axis to the plane of the laminate. - View Dependent Claims (10, 11, 12, 13)
