ABSTRACT:
A goggle (11) that includes an electrical defogging system includes a frame (13) and a transparent lens (15). The transparent lens includes an outside layer(51 or 61) and inside layer(53 or 63) spaced from the outside layer by a peripheral gasket (55 or 65). The inside layer has an indium tin oxide (ITO) coating. The ITO coating includes an interior heating zone (33) that is electrically isolated from the edge of the inside layer. Silver bus bars (45, 47) are printed atop the ITO coating along the opposing edges of the interior heating zone adjacent the top and bottom of the goggle lens. The edge isolation regions and the bus bars are positioned and oriented such that the region (48) where the bus bars cross the nose area(41) of the goggle lens is isolated from the interior heating zone(33). Further, the bus bar that passes along the bottom of the goggle lens extends upwardly along one side of the lens. The side section of this bar is electrically isolated (39 ) from the interior heating zone. As a result, the bus bar only contacts the interior heating zone along the top of the goggle lens and along the bottom of the eye regions (37) of the goggle lens located on either side of the nose area (41).
