Definitions

  • the invention relates to a windshield wiper for vehicles of all types with a circular, oscillating or linearly oscillating movement of the wiper blade. It is primarily intended for cars and trucks as well as buses; the invention is also applicable to vehicles of other types, for example helicopters, and also to rail vehicles and ships. Furthermore, they are also considered for their application on vehicle headlights.
  • the usual windshield wipers used in motor vehicles generally consist of a windshield wiper blade with the retracted wiper rubber and a windshield wiper arm which establishes the connection to a drive axle provided in the vehicle.
