Claim of US Patent No. 10,485,061

1. A heatable laminated side pane, comprising:an outer pane;
an inner pane;
a thermoplastic intermediate layer connecting the outer pane and the inner pane;
a transparent electrically conductive coating arranged in a planar manner between the outer pane and the inner pane, the transparent electrically conductive coating being divided by isolation lines into segments,
wherein the transparent electrically conductive coating includes a plurality of heating strips running between a first busbar and a second busbar, each heating strip having a length,
wherein each heating strip contains at least one segment,
wherein each heating strip is electrically insulated from each other heating strip,
wherein at least one heating strip is formed by at least two segments that are electrically conductively serially connected to each other via at least one electrically conductive connection element, wherein the at least one electrically conductive connection element is directly connected to the at least two segments, wherein the at least one electrically conductive connection element is laminated into the side pane,
wherein the length of each heating strip deviates by at most 15% from an average length of the plurality of heating strips, and
wherein the connection elements, the first busbar and the second busbar are formed as strips of an electrically conductive foil or as fired screen printing paste wherein the regions of the segments of all heating strips provided for contacting with the connection element are arranged immediately adjacent each other.
