Definitions

  • the present invention relates to a wiper system for a window of a motor vehicle with a screw-free fastening device, which has at least three spaced-apart fastening members, two of which lie on a connecting line and the third is spaced from the connecting line, and which comprises corresponding recording devices into which the Can engage fasteners.
  • a wiper system of this type is known from DE 198 33 404 AI.
  • the windshield wiper system disclosed there comprises a supporting structure on which a total of three fastening members designed as cylindrical plug pins are provided.
  • the plug pins are inserted axially into receiving openings, which are provided in special holding parts, which in turn are fastened to the vehicle body.
  • the plug pins on the one hand and the receiving openings on the other hand together form the fastening device for the windshield wiper system.
  • a disadvantage of this fastening device is that the plug pins arranged on the windshield wiper system and projecting therefrom can break off during storage of the windshield wiper systems before installation in the motor vehicle and during transport and handling.
  • the present invention therefore has the task of developing a wiper system of the type mentioned at the outset in such a way that it can be stored, transported and handled safely.
  • the measure according to the invention is as simple as it is effective, since it only provides a reduced number of fastening elements on the wiper system itself.
  • the wiper system can be used during storage, transport and handling, e.g. when installed in the motor vehicle, less likely to be damaged by yourself and less likely to damage other parts or injure the user.
  • the receiving devices provided on the system side are usually not very protruding and relatively solidly built parts which, on the one hand, are able to withstand the loads occurring during storage, transport and handling and, on the other hand, do not themselves pose any risk to other parts.
  • the corresponding fastening element is provided on the vehicle.
  • the fastening element is on the one hand protected and on the other hand does not interfere when assembling other parts on the motor vehicle.
  • the measure according to the invention thus makes the handling of the wiper system from manufacture to installation in the motor vehicle easier and safer, and costs are saved since fewer wiper systems between production and installation in the motor vehicle have to be rejected because of damage occurring.
  • all receiving devices are provided on the system side and all fastening members are provided on the vehicle side. This measure ensures maximum safety and ease of handling of the wiper system according to the invention.
  • a damping element in particular made of an elastic material, is arranged on the fastening member and / or on the receiving device.
  • At least one receiving device is preferably arranged on a wiper bearing.
  • the fastening points are as far apart as possible. This is made possible by the arrangement of the receiving device on the wiper bearing.
  • the moments transmitted by the windshield wipers are relatively low at these points.
  • a modification of this is characterized in that the receiving device is arranged on or in a support body of the wiper system. Such a support body is generally a very stable part of the wiper system, which is particularly well suited for accommodating the receiving device.
  • Another location that is suitable for arranging the receiving device is e.g. the flange to which the drive motor of the wiper system is flanged. This is taken into account by the further development in which the receiving device is arranged on or in the engine mount.
  • a receiving device which comprises a sheet metal feed is particularly inexpensive and easy to manufacture.
  • a receiving device can also be provided which comprises an eyelet.
  • an eyelet With such an eyelet, the fastening element is not held over its length, so that the transmission of moments is not so easy with it, but it is very easy to manufacture and therefore particularly inexpensive.
  • the fastening member is fastened to a holding part, which is connected to the vehicle, or is molded onto the latter.
  • the holding part with the fastening member can be produced, for example, in a separate manufacturing step and then fastened, for example, by a welding robot to the structural sheet metal of the vehicle.
  • the fastening element can also be fastened directly to a structural sheet metal of the vehicle or molded onto it. In this Case can be dispensed with an additional holding part.
  • the structure sheet of the vehicle is naturally particularly stable, which enables a firm and permanent positioning of the wiper system.
