Patent ID: 7714255

Claim:
A flexible heating subassembly, comprising: a flexible heater including a first lateral edge, and a second lateral edge opposite the first lateral edge; a first conductive bus bar disposed alongside the first lateral edge of the flexible heater; a second conductive bus bar disposed alongside the second lateral edge of the flexible heater; first and second rows of electrically conductive stitching, the first row of electrically conductive stitching electrically coupling the first conductive bus bar to the flexible heater, the second row of electrically conductive stitching electrically coupling the second conductive bus bar to the flexible heater; the first and second conductive bus bars adapted for coupling to a power source for powering the flexible heater; a first electrically insulating member interposed between the first conductive bus bar and the flexible heater and being secured therebetween by the first row of electrically conductive stitching, the first electrically insulating member preventing direct electrical contact between the first conductive bus bar and the flexible heater; and a second electrically insulating member interposed between the second conductive bus bar and the flexible heater and being secured therebetween by the second row of electrically conductive stitching, the second electrically insulating member preventing direct electrical contact between the first conductive bus bar and the flexible heater.
