Definitions

  • the invention is based on a wiper blade for a windshield wiper according to the preamble of claim 1.
  • Known windshield wipers have a wiper arm which is constructed from a fastening part and an articulated part articulated thereon with a wiper rod. At the free end of the
  • wiper rod is articulated a wiper blade.
  • This generally has a multi-link bracket system with one or more higher brackets, the ends of which are connected to lower brackets via joints. Of these, at least some have claws at their ends with which they have one
  • Support bracket system and spring rails inserted into the headrail allow the wiper strip to be adapted to a curved windshield with even contact pressure when wiping.
  • wipers are e.g. from the
  • ramp surfaces lead from the open side of the U-shaped cross-sectional profile of the higher bracket to the bearing holes. During assembly, they guide the bearing journals into the bearing openings, which enclose the assembled bearing journals over the entire circumference with a small bearing clearance.
  • the ramp surfaces are inclined to the side walls. Their inclination is limited by the material thickness of the side walls. This, in turn, cannot exceed a certain thickness, since the
  • the hinge pins are formed on the side walls of a connecting piece which laterally encompasses the subordinate bracket and is fastened to it by latching means.
  • the subordinate bracket is connected to a superordinate bracket via the connecting piece, in that the pivot pins of the connecting piece are mounted in bearing openings of the superordinate bracket.
  • the pivot pins are chamfered towards the parent bracket down to their feet, so that these inclined surfaces form a ramp for threading. They replace the shaped ramp surfaces on the higher bracket of known support bracket systems, which weaken the side walls of the U-shaped cross-sectional profile.
  • the side walls of the higher bracket of the support bracket system according to the invention advantageously have a uniform wall thickness in the area of the bearing opening. Therefore, the stirrups are very strong.
  • the high stability of the superordinate bracket improves the guidance of the subordinate bracket via the articulated connection, because the superordinate bracket provides more resistance to external loads and deforms less under pressure. Furthermore, it is guaranteed that the connection between the pivot pins and the bearing openings does not come loose automatically.
  • the higher-level bracket is easy to manufacture, since there are no additional ⁇ work steps to manufacture the ramp surfaces.
  • the connecting piece has, on one end face, an edge projecting from the superordinate bracket, which can serve as a stop and thus limits the movement of the brackets to one another in a defined manner.
  • the protruding edge is designed so that it covers the space between the brackets to the outside except for a movement gap. This makes the shape of the support bracket system more closed and there is less wind noise when driving. Since the connecting piece can be used in variants on all articulated connections of the mounting bracket system, there are large numbers of items that can be manufactured inexpensively using the injection molding process.
  • the connecting piece expediently consists of an elastic plastic and, after the injection molding, has the pivot pins and all the necessary locking means.
  • the locking devices are simply clipped onto a subordinate bracket by applying slight pressure.
  • the locking means can be designed as locking lugs which are arranged on elastically deformable spring tongues or wall parts and rest on the lower edge of the bracket or engage in recesses or depressions in the side walls.
  • the hinge pins on the side walls are formed on the connecting piece.
  • the side walls can be closed or can be designed like resilient tongues in the region of the joint pins.
  • the connecting piece When assembled, take the resilient tongues of the connector back into their original position and press the pivot pins into the bearing openings so that they are securely stored there.
  • the assembly of the connecting piece is also facilitated by integrally formed ramps inclined in the mounting direction on the latching lugs and the pivot pin.
  • the superordinate bracket is centered on the subordinate by centering pins which are arranged on the top wall of the superordinate bracket and engage in centering openings in the top wall of the subordinate bracket.
  • FIG. 2 shows a hinge connection in perspective and seen from below
  • FIG. 3 shows a connecting piece and a subordinate bracket
  • FIG. 4 shows the connecting piece according to FIG. 3 from below
  • FIGS. 5-6 variants of the connecting piece according to FIG. 4 7 shows a variant of a subordinate bracket
  • FIG. 8 shows a variant of FIG. 2.
  • a parent bracket 10 of a bracket system and a lower bracket 12 is shown before assembly.
  • the parent bracket 10 has a U-shaped cross-sectional profile, on the side walls 18 of which congruent bearing openings 16 are formed in the end region.
  • the subordinate bracket 12 also has a U-shaped cross-sectional profile and has molded-on claws 14 at the ends for holding a wiper strip. Both brackets 10, 12 are articulated to one another by a connecting piece 20.
  • Hinge pins 22 are formed on the outside of the side walls 90 of the likewise U-shaped connecting piece 20, while locking means in the form of locking lugs 52 are arranged on the inside.
  • the pivot pins 22 have ramps 24 which are inclined in the assembly direction and which are bevelled up to the foot and thus can easily slide into the bearing openings 16.
  • the parent bracket 10 compresses the side walls 90 somewhat. So that the side walls 90 can also yield when the connecting piece 20 is mounted on the subordinate bracket 12, the latter has an area 46 which recesses inwards in the area of the side walls 90.
  • the side walls 44 demonstrate in one variant 3 shows an opening 48 above the recess 46.
  • the side walls are divided in a variant of the connecting piece 20 according to FIG. 3, the individual areas being designed as resilient tongues 26, 50.
  • the hinge pins 22 are integrally formed on the middle spring tongues 26, while the detents 52 are arranged on the adjacent spring tongues 50.
  • the side walls are only partially cut free, so that a robust connecting piece 20 is created, which is also easy to assemble.
  • the connecting piece 20 Since the superordinate bracket 10 cannot exert any noteworthy compressive forces on the subordinate bracket 12 via the beveled hinge pin 22, the connecting piece 20 has a roof-shaped system 30 on a top wall 28 to the superordinate bracket 10, which forms a kind of cutting edge bearing and reliably transmits the compressive forces , So that the detent 52 can be formed better, 28 openings 56 are provided in the top wall.
  • the connecting piece 20 is, for example, attached to the subordinate bracket 12 or 42 (FIG. 3).
  • the lateral spring tongues 50 of the connecting piece 20 are widened outwards in that the side walls 44 of the bracket 42 slide over the ramps 64 of the latching lugs 52, which are formed on the inner surfaces of the connecting piece 20.
  • the connecting piece 20 engages with the locking lugs 52 on the lower edge 54 of the side walls 44 of the subordinate bracket 12 or 42.
  • the spring tongues 26, 50 or the locking lugs 52 can also have other shapes.
  • the detents 60 5 have, for example, a semicircular shape and are arranged approximately in the middle of the inside of the spring tongues 58. In the assembled state, they engage in recesses 62 (FIG. 3) or in corresponding impressions in the side walls 44 of the subordinate bracket 42.
  • the connecting piece 20 encompasses the subordinate bracket 12 in the middle, while it is supported with the pivot pins 22 in the bearing openings 16 of the superordinate bracket 10 (FIG. 2).
  • An edge 32 which is formed on an end face of the connecting piece 20 protruding from the parent bracket 10, covers the end face 36 of this bracket except for a movement gap 34. It is designed in a wedge shape and forms a harmonious transition between the higher bracket 10 on the one hand and the lower bracket 12, 42 on the other hand. In addition, it can serve as a stop and limit the swivel angle of the brackets 10 and 12, 42.
  • the edge 32 on the connector 20 can also be omitted.
  • the connecting piece 20 is centered on the subordinate bracket 12 with an integrally formed centering pin 84 (FIG. 4), which is arranged on the top wall 28 and between the joint pin 22. In addition, it has an elongated shape and extends to both sides of the pivot pin 22. In the assembled state, it engages in a correspondingly formed centering opening 86 in the top wall 88 of the subordinate bracket 42 and improves the guidance of the subordinate bracket 12 relative to the superordinate bracket 10th
  • a connecting piece 66 is first preassembled on the higher bracket 10 and then clipped into a lower bracket 72 (FIG. 8). The connecting piece 66 is mounted after the preassembly with the pivot pins 22 in the bearing openings 16 of the higher bracket 10.
  • the connecting piece 66 has transverse spring tongues 68 which engage through an elongated opening 74 in the top wall 78 of the subordinate bracket 72.
  • the tabs 76 are formed from the material that is produced in the manufacture of the opening 74. Relatively long spring tongues 68 with good spring characteristics can be realized by the tabs 76. In principle, however, short spring tongues 68 are also possible, the latching lugs 70 of which are supported directly on the edge of the opening 74 or on short tabs 76.
  • Centering pins 80 are integrally formed on the top wall 78 of the connecting piece 66, which engage in centering openings 82 of the subordinate bracket 72, which lie in the longitudinal direction on both sides of the opening 74.
