Definitions

  • the invention relates to a Wisc arm for motor vehicles.
  • the wiper rod in one piece from sheet metal for windshield wipers.
  • the wiper rod has a U-shaped connecting hook which, over its entire length, consists of sheet metal folded in two or three layers. Because of this, the connecting hook has a not inconsiderable overall height which also determines the air resistance of the entire windshield wiper.
  • the wiper arm is relatively far from the window to be wiped.
  • the object of the invention is to further develop a wiper arm of the known type in such a way that the overall height is reduced while the load capacity remains the same.
  • the object is achieved by the features of claim 1.
  • the essence of the invention is to design the connecting hook consisting of a first and a second hook web in such a way that the hook web facing the window to be wiped has a smaller thickness than that of the hook web facing away from the window.
  • the advantage of the embodiment according to claim 2 is that the hook web facing away from the pane is approximately twice as thick as the hook web facing towards the pane, so that simple manufacture is possible.
  • the wiper rod is integrally formed with the connecting hook. The advantage here is the aesthetically uniform image of the wiper arm and the ease of manufacture.
  • the first and second hook webs run essentially parallel to one another. This has the advantage that a connecting element for fastening the wiper blade can be easily inserted into the hook.
  • the wiper rod is made of a one-piece sheet metal part.
  • the first hook web is formed from two-day sheet metal and the second hook web from single-layer sheet metal. In this way it is particularly easy to reduce the thickness of the second
  • 1 is a side view of a wiper arm
  • FIG. 2 is a view of the wiper arm according to FIG. 1 from below,
  • FIG. 4 shows a side view of the connecting hook in accordance with FIG. 3
  • 5 shows a cross-sectional view according to the section line VV in FIG. 4,
  • FIG. 6 shows a sheet metal blank for the connecting hook according to FIG. 3,
  • FIG. 8 is a bottom plan view of the connecting hook according to FIG. 3.
  • a wiper arm 1 for the windshield wiper device on a motor vehicle has a fastening arm 4 connected to a drive shaft 2 arranged on the motor vehicle via a receiving bush 3.
  • a wiper rod 6 is articulated via a joint 7.
  • the wiper rod 6 has a connecting hook 8, which can be detachably connected to a wiper blade.
  • the commercially available mounting arm 4 has a U-shaped profile and is formed from sheet metal. At the end 5 of the fastening arm 4 and at the end of the wiper rod 6 facing the fastening arm 4, aligned bearing bores 9 are provided, in which a bearing pin 10 is received and around which the wiper rod 6 can be pivoted relative to the fastening arm 4.
  • the wiper rod 6 has a support arm 11, which extends from the joint 7 to the free end of the wiper rod 6, and the arm 11 attached to it. closing, with this one-piece connecting hook 8.
  • the support arm 11 has a U-shaped cross section with a Tragarai base 12 and laterally adjoining support arm legs 13, 14. The height of the legs 13, 14 decreases along the longitudinal direction 15 of the wiper rod 6.
  • One of the bearing bores 9 is provided in each of the legs 13 and 14.
  • a holding web 17 which runs parallel to the base 12 and projects in the direction of the leg 13 and which is formed in one piece with the leg 14. Between this and the journal 10, a tension spring 18 is provided to apply force to the wiper rod 6 in the direction of a window to be wiped.
  • the connection hook 8 has a U-shaped cross section in the view according to FIG. 1. It is formed by an upper hook web 19 which is formed in one piece with the support arm 11, a curved hook base 20 which is formed in one piece with it and a lower hook web 21 which is formed in one piece with the hook base 20 and runs parallel to the upper hook web 19.
  • the upper hook web 19 has a thickness D A.
  • the lower hook web 21 has a thickness D E.
  • the hook web 19 and large parts of the hook base 20 up to a transition 22 have an outer strand 23 and two inner webs 25 which are unfolded on these from both long sides and run parallel to this and are separated in the middle by a longitudinal groove 24.
  • the webs 25 end in the area of the transition 22. Only the outer web 23 continues and forms det beyond the transition 22, the lower hook web 21.
  • the inner webs 25 continuously merge into the legs 13 and 14 and the outer web 23 into the floor 12.
  • the hook base 20 has an essentially uniform curvature with respect to the bending axis 27.
  • the wiper rod 6 In the manufacture of the wiper rod 6, a one-piece sheet metal blank is assumed, the front end of which is shown in FIG. 6.
  • the inner webs 25 are connected to the outer web 23 via fold lines 28.
  • the inner webs 25 are unfolded onto the outer web 23 to form a longitudinal groove 24.
  • the legs 13 are bent by 90 ° relative to the base 12, so that the intermediate product shown in FIG. 7 is produced.
  • the lower hook web 21 and part of the double-layer arrangement of inner webs 25 and outer web 23 are bent around the bending axis 27, so that the connecting hook 8 shown in FIGS. 3, 4 and 8 is formed.
  • An advantage of manufacturing the wiper rod 6 from a one-piece molded sheet metal is that a complete aesthetic total pressure is created.
  • the design of the connecting hook 8 with an upper hook web 19 and a lower hook web 21 of half the thickness has the advantage that the total height H of the connecting hook 8 can be reduced while the height A of the hook opening 29 remains the same.
  • the shear forces occurring during the wiping process can be absorbed by the upper hook web 19 and the hook base 20.
  • the wiper rod 6 lies closer to the window to be wiped, so that the wind resistance that occurs, which is particularly important at high driving speeds, becomes less.
  • the wiper arm 1 is less visually significant because it lies closer to the window.
