Definitions

  • the invention relates to a wiper blade according to the preamble of the independent claim.
  • this is intended to ensure the most uniform possible distribution of the wiper blade contact pressure on the window starting from the wiper arm over the entire wiping area swept by the wiper blade.
  • the support element thus replaces the elaborate mounting bracket construction with two arranged in the wiper strip spring rails, as practiced in conventional wiper blades (DE-OS 15 05 397).
  • the support element causes not only the distribution of the contact pressure but also the necessary transverse reinforcement of the rubber-elastic wiper strip.
  • the support element has a
  • Wiper lip The wiper is tilted in this position as far as it rests with its outer upper shoulder on the underside of the wiper strip back. Due to the oscillating wiping movement of the windshield wipers, reversal points result in the end positions of the movement. Here, the wiper works in the opposite direction and then takes back a dragged working position.
  • Umklappvorgang arises especially in wiper blades with a resilient support element an annoying flip-over noise.
  • the squeegee is very much elastically deformed in the area of the tilting bridge. This leads to a permanent deformation of the wiper blade profile in the course of the operating time, which at first only affects the wiping action of the windscreen wiper, but later can even prevent the folding over.
  • the wiper blade with the features of the main claim has the advantage that a soft cushion allows the tilting movement as such, the impact of opposing
  • the tilting movement takes place at a defined point or along a defined line.
  • the soft pad is spared, since the tilting bridge largely absorbs the mechanical forces such as contact pressure or tensile force over the disc.
  • the tilting ridge is flanked by two grooves whose groove base form the tilting ridge, as a rule, it is advantageous to accommodate the soft cushion at least in one groove.
  • the groove can be filled to save material only partially or completely. If the groove is only partially filled, it is advantageous to provide the soft padding partially on a surface or an edge, in the area of which the folding-over noise arises. If the overturning noise is only noticeable in a reversal position, it is also possible to completely or partially fill a groove with a soft cushion in order to save material. In general, however, the pads are attached to both grooves.
  • the soft pad can be kept in that it is at least partially completely enclosed by the material of the wiper blade rubber. This also results in a protection of the soft cushion against environmental influences. This protection is improved when the soft pad is completely covered.
  • the soft padding takes over the tasks of the usual tilting bridge.
  • the soft pad can partially or completely fill the area between the wiper strip back and the wiper. The folding process is thus harmonious and fluid, so that Umklappge Hursche are already avoided in the beginning.
  • the soft pad is extruded together with the squeegee. It may be extruded as an additional material or admixed with the squeegee material. In the event that the material of the soft cushion can be extruded unfavorably, it can also be glued or glued. An optimal filling results when the soft pad is filled in the at least one groove and cures there.
  • FIG. 1 shows a wiper blade according to the invention in a perspective illustration with a wiper arm indicated by dash-dotted lines
  • Figure 2 is a section along line II-II in Figure 1 and the
  • FIGS. 3 to 11 show different variants of a wiper rubber profile according to the invention in section, analogously to FIG. 2.
  • An illustrated in Fig. 1 wiper blade 10 has a band-like elongated, resilient, one or more parts supporting element 12, which in unloaded
  • Condition is curved in the longitudinal direction.
  • At the side facing away from the disc 14 to be wiped convex upper or outer band side 16 of the support member is disposed in the central portion thereof, for example, surface adjacent to this terminal device 18, with the help of the wiper blade 10 with a guided on the bodywork of a motor vehicle, driven wiper arm 20th can be releasably connected.
  • counter-connection means not shown in detail are provided, which with the connection device 18 of the wiper blade in the sense of
  • Curvature of the voltage applied to the disc 14 with its ends 10 ', still unloaded wiper blade 10 is stronger than the maximum disc curvature. It has - unloaded - so opposite the disc a concave course.
  • the wiper blade 10, with its wiper blade 28 performing the wiping work lays against the disk surface 14 over its entire length and changes into a working position which approximates the extended position.
  • a tension builds up in the band-like, spring-elastic support element 12, which ensures a proper contact of the wiper strip 24 or its wiper lip 28 over its entire length on the vehicle window 14.
  • the wiper blade 10 must be able to constantly adapt to the respective position and the course of the disc surface 14 relative to the wiper arm 20 during its wiping movement (double arrow 30). Therefore, a pivotal movement (double arrow 32) about the hinge axis of the connection connection enabling articulated connection between wiper arm 20 and wiper blade 10 is necessary.
  • the wiper blade 10 is shown in section. It can be seen that the support member 12 consists of two individual spring rails that receive the wiper strip 24 between them.
  • the wiper strip 24 has a wiper strip back 34 with first longitudinal grooves 36, in which the rails of the support element 12 are embedded. Both the support element 12 and the wiper strip back 34 are overlapped by a Windabweisang 38.
  • the wiper strip 24 has second longitudinal grooves 40 which separate the wiper strip back 34 via a tilting region 41 of a wiper wedge 42, on the underside of which
  • Wiper lip 28 is formed.
  • the wiper blade 10 is moved back and forth along the double arrow 30, so that the wiper lip 28 is pulled over the disc 14.
  • wiper wedge 42 is placed in a drag position, which causes the second longitudinal grooves 40 to be reduced in size on one side and widened on the other side, the second longitudinal groove 40 being completely closed in the region of the reduction.
  • the Wiper wedge 42 consequently strikes one of the longitudinal edges 44 on an underside of the wiper strip back 34. This creates a clearly audible sound.
  • At least one longitudinal groove 40 is now a soft pad 46, which dampens the folding movement at the time of folding the wiper wedge 42, so that there is little or no audible stop of the longitudinal edges 44 on the underside of the wiper strip back 34.
  • the wiper strip back 34 is connected to the wiper wedge 42 via a tilting web 48.
  • the second longitudinal grooves 40 extend on both sides of the tilting web 48 in the longitudinal direction of the wiper blade 10.
  • the tilting web 48 thus forms a pivot point or a tilting line for the Umklappterrorism.
  • the second longitudinal grooves 40 are filled with soft pads 46, so that the folding movement are damped at both reversal points of the wiping movement.
  • the wiper strip back 34 has recesses 50 in the region of the tilting web 48, which form undercuts with respect to the second longitudinal grooves 40 and which allow the soft pads 46 to hold securely. Further, the wiper strip back 34 has third longitudinal grooves 52, which are arranged relative to the second longitudinal grooves 40 further away from the disc 14 and under extreme conditions also on
  • Soft upholstery 46 are also arranged in these third longitudinal grooves 52.
  • soft pads 46 are arranged in the second longitudinal grooves 40 so that the course of the outer surfaces 54 are taken up by the outer sides of the soft pads 46 and continued to the outer sides of the wiper strip back 34. This results in a harmonious appearance, which also
  • Bridge 56 are connected. Moisture, ice and snow are thus even more effective Ingress prevented, so that recognizable this arrangement is suitable for so-called winter wiper blades.
  • the second longitudinal grooves 40 are each only partially filled, which allows free movement of the wiper wedge 42.
  • Figure 5 are soft upholstery
  • the longitudinal edges 44 can thus freely initiate the folding process and then dip into the soft pad 46 before they hit the wiper strip back 34.
  • Remedy against weathering can provide an arrangement according to Figure 7, in which the soft pads 46 are arranged only in an inner, oriented on the tilting ridge 48 area.
  • FIG. 9 shows how the soft pad 46 can be further protected against environmental influences.
  • the wiper strip back 34 has for this purpose an inner longitudinal channel
  • FIGS. 10 and 11 Variants that do not require a tilting web 48 are shown in FIGS. 10 and 11.
  • the second longitudinal grooves 40 merge into one another, so that only one tilting region 41 is formed.
  • the wiper strip back 34 and the wiper wedge 42 are connected directly via the soft pad 46.
  • the distance between the wiper strip back 34 and the wiper wedge 42 is selected so that in conjunction with the properties of the soft pad 46 the necessary towing position is reliably achieved even under different friction conditions.
  • the soft pad 46 completely fills the area between the wiper strip back 34 and the wiper wedge 42, laterally even slightly protrudes.
  • dash-dotted lines it is also possible, as indicated by dash-dotted lines, to provide this area with a slim waist 60. Depending on the degree of hardness of the soft pad 46, this waist 60 may be slimmer or wider.
  • the soft pad 46 As material for the soft pad 46 are very soft, highly flexible and possibly compressible substances. It is conceivable, for example, a mousy-like filling, in which case, however, a dense outer skin is required to prevent ingress of water into the soft pad 46
