摘要： A heatable vehicle window including at least three different heating zones. A conductive coating is divided into at least three different heatable coating portions which are spaced apart from one another. A top bus bar includes a step or protruding portion which extends toward the bottom bus bar at an area of an intermediate one of the heatable coating portions. This protruding portion enables, for example and without limitation, a rain sensor or toll device to efficiently transmit and/or receive signals (e.g. IR signals, RF signals, or the like) through the window at an area behind the protrusion where the coating has been deleted. Because of the division of the coating into at least three different heatable coating portions, approximately uniform current distribution is enabled along the top bus bar (even at the protruding portion thereof) so as to reduce the likelihood of overheating.

摘要翻译： 包括至少三个不同加热区域的可加热车窗。 导电涂层被分成至少三个彼此间隔开的不同的可加热涂层部分。 顶部母线包括在可加热涂覆部分的中间一个区域中朝向底部汇流条延伸的台阶或突出部分。 该突出部分能够（例如但不限于）雨水传感器或收费设备，以在涂层具有的突起的后面的区域有效地透过窗口传输和/或接收信号（例如，IR信号，RF信号等） 被删除。 由于将涂层分成至少三个不同的可加热涂层部分，所以沿顶部母线（即使在其突出部分）也能够实现大致均匀的电流分布，以便减少过热的可能性。
