Abstract:
1. A heatable article comprising: a first continuous bus bar having a length; a second continuous bus bar having a length spaced from the first bus bar, wherein the second bus bar is shorter in length than the first bus bar; an electrically conductive member, wherein portion of the conductive member between the first and second bus bars comprises a plurality of spaced electrically conductive segments in physical and electrical contact with the first and second bus bars; an electrically conductive segment defined as an intermediate segment between adjacent segments of the plurality of conductive segments, the intermediate segment in electrical contact with one of the bus bars and electrically isolated from the other one of the bus bars to prevent current from moving from one of the bus bars through the intermediate segment to the other one of the bus bars, and at least one of the segments selected from the group of the intermediate segment, the plurality of segments and combinations thereof having varying width as the distance from the first bus bar toward the second bus bar increases, wherein length of the portion of the conductive member between the first and second bus bars and adjacent the first bus bar is greater than length of the portion of the conductive member between the first and second bus bars and adjacent the second bus bar, and the length of the portion of the conductive member between the first and second bus bars continuously decreases as the distance from the first bus bar increases, wherein the length of the conductive member is measured between ends of a bus bar.
