Abstract
A window heating system, in particular for heating a window of a motor vehicle, includes a resistance heating device, applied onto or integrated into the window, that is connectable to a heating voltage source via terminal contacts by way of an electrical switching device. The switching device is a semiconductor switching device arranged directly on the window to be heated.
Claims6
A window heating system for heating a window of a motor vehicle, comprising:
- a resistance heating device one of applied onto and integrated into the window, the resistance heating device including a conductor loop having terminal regions;
- and
- a semiconductor switching device for connecting the resistance heating device to a heating voltage source via terminal contacts, the switching device being situated directly on the window, the switching device being contacted directly to the terminal regions of the conductor loop, at least one of the terminal regions forming a terminal lug that provides an electrical contacting and provides a mechanical retention of the switching device on the window.
