Electrically Heatable Glazing Panel
First Claim
1. An electrically healable glazing panel comprising a substrate, a substantially transparent, electrically conductive coated layer divided into at least two separated zones and at least two spaced bus bars distributing electrical energy to the conductive layer zones, characterised in that the conductive layer zones have shapes with their longest dimension following the profile of the longest substrate edge that is heated at full length and extend, at least partly, from the shortest substrate edge towards an opposite short edge of that substrate.

Abstract
Electrically heatably glazing panel and process for making the same, comprising a substrate, a substantially transparent, electrically conductive coated layer divided into at least two separated zones and at least two spaced bus bars distributing electrical energy to the conductive layer zones. The glazing panel is characterised by the fact that the conductive layer zones have shapes with their longest dimension following the profile of the longest heated substrate edge and extend, at least partly, from the shortest substrate edge towards an opposite short edge of that substrate.

31. Process for heating an automotive side or rear window made of an electrically heatable glazing panel comprising a substrate, a substantially transparent, electrically conductive coated layer divided into at least two separated zones and at least two spaced bus bars distributing electrical energy to the conductive layer zones, characterised in that an electrical current is forced in the conductive layer zones and in that the zones have been shaped with their longest dimension substantially parallel to the longest edge of the substrate that is heated at full length so as to extend from the shortest edge of the substrate towards an opposite short edge of that substrate.

32. A heatable automotive side or rear window made of an electrically heatable glazing panel able to open the window by sliding out of a window frame through at least one of the window edges while uncovering a substrate edge of the panel and comprising, coated on the substrate, a substantially transparent, electrically conductive coated layer divided into at least two separated zones and further comprising at least two spaced bus bars distributing electrical energy to the conductive layer zones, characterised in that the conductive layer zones have shapes with their longest dimension substantially parallel to the uncovered edge of the substrate.
