  • the temperature sensor is advantageously designed pre-assembled and already connected to the system part when installed in the motor vehicle.
  • the coupling of the temperature sensor to the vehicle window is effected by spring force, wherein, however, not the temperature sensor itself, but the assembly-favorable molded part of the system is pressed against the vehicle window.
  • the installation effort can be kept very low.
  • the temperature sensor does not make a firm connection with the vehicle window, as a result of which, as required, both the vehicle window and the temperature sensor can be exchanged individually.

  • the free end portions of the spring arms form three attachment points that allow a positionally accurate alignment of the temperature sensor on the vehicle window.
  • the spring force of the third, individually aligned spring arm amount is approximately equal to the total spring force of the two mutually parallel spring arms.
  • the device preferably produced as a stamped bent part, which forms the contact part with the integrally formed spring arms, advantageously consists of a good heat-conducting material, which ensures a good thermal coupling of the temperature sensor to the vehicle window.

  • the underside of the contact part (2) is formed as a flat surface which can be pressed by the spring arms (3a, 3b, 3c) to a vehicle window.
  • a good thermal coupling of the temperature sensor (1) is given to the vehicle window, with the proviso that the vehicle window in the contact pressure of the system part (2) forms a flat surface.
  • the surface contact between the contact part (2) and the vehicle window can be improved if a heat-conductive film (12), preferably ductile, is arranged between the contact part (2) and the vehicle window, which compensates any unevenness between the contact surfaces of these components.
