Definitions

  • Windshield wiper device in particular for a motor vehicle
  • the invention relates to a windshield wiper device according to the preamble of the 5 independent claims.
  • windshield wiper devices which have a wiper bearing in which a wiper shaft is mounted. These windshield wiper devices are fastened to the vehicle by means of a fastening element, such as, for example, a screw with a rubber sleeve, a rivet or the like. It is also known
  • a windshield wiper device is known from EP-A-0 739 792, in which the wiper bearing has a predetermined breaking point, which occurs when a pedestrian collides breaks on the wiper shaft and thus separates the windshield wiper device from the motor vehicle.
  • the windshield wiper device according to the invention with the features of the main claim has the advantage that when a pedestrian hits the wiper shaft, the windshield wiper device can detach from the vehicle body and the wiper shaft can thus disappear inside the body of the vehicle without the windshield wiper device being destroyed in the process. According to the invention, this is brought about by a predetermined breaking point on the fastening element. This reduces the risk of injury to a pedestrian when hitting the windshield wiper device and, in the event of an accident, merely destroys the fasteners, which are easy to replace.
  • the longitudinal extent of the fastening element is essentially transverse, in particular perpendicular to the longitudinal extent of the wiper shaft. In this way, one acts on impact
  • the 5 fastening element is designed as a screw, bolt or rivet.
  • the predetermined breaking point is advantageously designed as a circumferential notch in the fastening element.
  • the predetermined breaking point is advantageously arranged in the region of the fastening element which lies in the assembled position between the windshield wiper device and the motor vehicle.
  • the fastening element is at least partially encompassed by an elastic damping element, so that vibrations of the windshield wiper device are not transmitted to the vehicle or the vehicle body.
  • This decoupling of the windshield wiper device and the vehicle body results in improved vibration behavior and reduced noise from the windshield wiper device in the motor vehicle.
  • Figure 1 shows a windshield wiper device according to the invention in perspective
  • FIG. 2 shows the wiper bearing of a windshield wiper device according to the invention in a perspective view
  • FIG. 3 shows a fastening element of a windshield wiper device according to the invention in a side view
  • FIG. 4 shows a fastening element of a windshield wiper device according to the invention in a partial section from FIG. 2.
  • FIG. 1 shows the windshield wiper device 10 according to the invention in a perspective view.
  • This essentially consists of a curved support tube 12 which has two ends, to each of which a wiper bearing 14 is attached.
  • a wiper motor 16 with a gear 18 is arranged on the carrier tube 12, which drives a crank 22 on its output shaft 20.
  • the wiper bearings 14 each support a wiper shaft 24, to which wiper arms (not shown here) are attached with wiper blades.
  • a further crank 26 is fastened in a rotationally fixed manner to the wiper shaft 24 and is moved by a push rod 28, which is articulated with its end facing away from the crank 26 on the crank 22 of the wiper motor 16.
  • the wiper bearing 14 essentially has three sections.
  • a first fastening section 30 is used to fasten the wiper bearing 14 to the support tube 12.
  • the fastening section 30 is designed as a cylindrical connecting piece which is pushed into the interior of the support tube 12.
  • the attachment section 30 also has cutouts 32, so that the support tube 12 can be crimped onto the attachment section 30.
  • the carrier tube 12 can also be screwed, riveted or cast.
  • the bearing section 34 is fastened to the fastening section 30 transversely to the fastening section 30.
  • This essentially consists of a tube, the longitudinal axis of which extends approximately perpendicular to the fastening section 30.
  • the wiper shaft 24 is mounted in this tube.
  • bearing sleeves, sealing sleeves or similar means can of course also be introduced or cast into the tube.
  • a mounting section 36 is arranged on the bearing section 34, essentially diametrically to the fastening section 30.
  • the mounting section 36 essentially comprises a flat plate 38 which extends approximately parallel to a longitudinal plane which is defined by the axis of rotation of the wiper shaft 24. On the - in the longitudinal direction of the
  • Bearing section 34 considered - Lateral walls 40 are arranged on the sides of the plate 38 for stiffening and for better connection of the plate 38 to the bearing section 34. Furthermore, the plate 38 has a notch 42, which serves to receive a fastening element 44.
  • the fastening element is designed here as a screw, which is encompassed by a rubber sleeve as a damping element 46.
  • Rubber sleeve 46 is designed in the form of a circular disk and has a diameter which corresponds precisely to the distance between the lateral walls 40 of the mounting section 36, so that a secure, damped mounting of the
  • Wiper bearing on the motor vehicle is guaranteed.
  • the fastening element 44 is designed as a screw, which is of substantially elongated shape, has a thread 47 at one end and a hexagon 48 at the other end.
  • a circumferential notch 50 is arranged approximately in the middle of the longitudinal extent of the fastening element 44 as a predetermined breaking point.
  • the fastening element 44 can also be designed as a rivet or as a bolt.
  • Windshield wiper device 10 shown in a partial sectional view.
  • the plate 38 of the mounting section 36 lies on a fastening piece 52, which forms part of the vehicle body.
  • the fastening piece 52 has a hole through which the fastening element 44 with its thread 46 is pushed through and fixed by means of a screw nut or is screwed directly into the fastening piece.
  • the hexagon 48 of the fastening element 44 is arranged on the side of the plate 38 facing away from the fastening piece 52.
  • the so 11 fractions are located in the area of the contact surface 54 between the fastening piece 52 of the vehicle body and the plate 38 of the mounting section 36.
  • the damping element 46 is formed in several parts by adding a second cylindrical section to the screw
  • the predetermined breaking point 50 of the fastening element 44 is loaded by this shear force, in particular in such a way that it breaks off and the wiper shaft 24 dives into the interior of the vehicle.
  • the wiper shaft 24 can be designed to be axially displaceable by means of a spring or foam element.
  • the predetermined breaking point will advantageously not break until the other measures have been exhausted, i.e. when a predetermined force is exceeded.
  • the wiper bearing 14 is designed as a one-piece cast part, aluminum or zinc die casting being particularly suitable here. However, plastic can also be used as the casting material. Alternatively, it can also be designed in several parts. Other connection concepts can of course also be used as the fastening element 44. In principle, the solution shown here can also be used for any drives on the motor vehicle other than the wiper drive. In particular, the device shown here can also be provided for fastening the wiper motor 16 in a motor vehicle with a so-called “direct wiper drive”, in which there is no push rod gear and the wiper shaft 24 is driven directly via a reduction gear.
