Definitions

  • the invention relates to a wiper blade for cleaning vehicle windows with the features of the preamble of claim 1.
  • a wiper blade is known in which a wiper body made of elastic material is held with its upper region on a wiper blade frame.
  • the wiper body is designed overall as a foldable hollow body and has a drop-like shape in its cross section, two pliers-like extensions extending from the top of the wiper body in the direction of the vehicle window. The longitudinal edges of these extensions form two parallel wiper lips which, in the normal state, lie close together on the vehicle window.
  • An additional sponge strip and / or scraper is arranged in the space delimited by the forceps-like legs, which in the normal state is pulled back with respect to the wiper lips and enclosed by the forceps-like legs.
  • a washing liquid channel which is elastically deformable by the washing liquid pressure, runs longitudinally in the wiper body.
  • the washing liquid channel When viewed in cross section of the foldable wiper body, the washing liquid channel has a ring-segment-shaped shape, the ring segment on both sides extending into and ending in the forceps-like legs.
  • the cross section of the washing liquid channel increases under the pressure of the washing liquid conveyed, and the wiper body unfolds in such a way that the wiper lips pivot laterally outward and move away from the driving remove the test window.
  • the previously inner wall of the washing liquid channel, to which the sponge strip and / or scraper is attached is turned into the vehicle window.
  • the sponge strip and / or scraper come into contact with the vehicle window, whereas the wiper lips are without contact with the vehicle window.
  • the wiper body folds back into its normal position described at the beginning due to elastic restoring forces or additional spring elements inserted into the wiper body.
  • the object of the invention is therefore to improve a wiper blade of the type described in the introduction in such a way that the required good wiping quality is maintained over a longer period of time.
  • the wiper strip is provided with an internal stability and strength, which corresponds to that of conventional wiper strips, while ensuring the required flexibility.
  • a second wiper lip improves the wiping quality in normal wiping operation.
  • the wiper strip is designed in such a way that only the section of the washing liquid channel which faces the vehicle window and to which the intensive cleaning element is attached is elastically deformed under the pressure of the washing liquid conveyed. This deformation is significantly less than in the known wiper blade, so that its proper function is maintained over a much longer period of time before material fatigue occurs.
  • the wiper lips are not included in the elastic deformation to bring about the intensive cleaning process, the elastic properties of the elastically deformable section of the washing liquid line, to which the intensive cleaning element is fastened, are reduced to a negligibly small extent the wiping quality.
  • a sufficiently strong pressing of the intensive cleaning element against the vehicle window is ensured even if the relevant section of the wall of the washing liquid channel has aged.
  • the wiping quality can hardly deteriorate if, during normal wiping, the intensive cleaning element between the two wiping lips rests on the vehicle window with only slight pressure due to the reduced restoring forces of the washing liquid channel.
  • a development according to claim 2 has the advantage that the intensive cleaning element can be connected independently of the remaining wiper strip with the hose forming the washing liquid channel to form a prefabricated component and then in the open, channel-like cavity Back bar can be inserted and fastened in this.
  • a further development according to claim 3 is recommended, according to which the hose which forms the washing liquid channel is in the depressurized state has a flat cross-sectional shape.
  • the hose should be designed in such a way that its inner sides rest on one another in the unpressurized state or are only a short distance apart. Due to the elastic restoring forces of the hose, the intensive cleaning element is pulled back from the vehicle window when the pressure of the washing liquid decreases.
  • a further improvement of the function of the intensive cleaning element is achieved by a further development. Because the intensive cleaning element is supported laterally on the subsequent wiper lip during wiping operation, the effective lever arm of the intensive cleaning element between this supporting point and the surface of the vehicle window is shortened. As a result, the elastic deformability of the lower part of the intensive cleaning element is reduced, which in turn enables a stronger cleaning effect of the intensive cleaning element to be achieved.
  • a further development according to claim 8 is preferred, according to which the intensive cleaning element is a bristle strip.
  • This development has the advantage over an intensive cleaning element consisting, for example, of a sponge or hard sponge or the like that the rigidity of the intensive cleaning element required for the wiping process or cleaning process with simultaneous required elasticity, in particular over the length of the wiping surface ste, can be adapted much better to the existing conditions.
  • a development according to claim 10 has the advantage that the washing liquid is brought directly to the location of the vehicle window where it is needed directly.
  • the wiper strip has a wiper strip body produced by extrusion, which consists of the back strip and the two wiper lips, each of which is integrally connected to the back strip via an elastic tilting web.

  • Wiper strip of Fig. 4 in intensive cleaning operation shows a wiper blade which has a wiper blade frame 1, on which a wiper strip 2 made of elastic material is held and guided.
  • the wiper blade frame 1 is composed in a cascade of a main bracket 3, two intermediate brackets 4 and four claw brackets 5 with two pairs of claws 6 each.
  • the main bracket is provided approximately in the middle with a so-called hanging box 7, which is designed for pivotable connection to a wiper arm, not shown.
  • the two intermediate brackets 4 are each articulated like a balance bar at the opposite ends of the main bracket 3 and the claw brackets 5 are each articulated like a balance beam at the opposite ends of the intermediate bracket 4.
  • FIGS. 2 to 5 Further details of the invention, which relate primarily to the wiper strip 2, can be seen from FIGS. 2 to 5.
  • the exemplary embodiments of wiper strips 2 shown in these FIGS. 2 and 3 and 4 and 5 show a basic structure which is basically the same and which will first be described.
  • the wiper strip 2 has a back strip 8, which is divided into an upper and a lower part by a longitudinal groove 9 on the opposite longitudinal sides.
  • the longitudinal grooves 9 are formed so that the pairs of claws 6 of the claw brackets 5 of the wiper blade frame 1 engage in these longitudinal grooves 9 and thus can hold and guide the wiper strip 2.
  • a spring rail 10 is arranged in a channel which is closed in cross section and extends along the back bar 8.
  • the spring rail 10 and the channel in question are arranged centrally with respect to the width of the back bar 8. It would also be conceivable that more than one spring rail 10 can be present. For example, two spring rails 10 could be provided, each in a closed channel or in a further one on the longitudinal cables. th the back bar 8 provided longitudinal groove can be arranged. The number of spring rails and their spring characteristics is selected so that a targeted distribution of the contact forces entered into the wiper strip 2 via the claw pairs 6 are distributed uniformly or unevenly over the length of the wiper strip 2. The manner in which the spring rails are arranged on or in the back strip 2 is more dependent on the type of manufacture of the base body of the wiper strip 2. An arrangement of a spring rail 10 in the manner shown in FIGS. 2 to 5 is preferred if, as in the present case, the base body of the wiper strip 2 is produced by extrusion.
  • a washing liquid channel 11 runs in the longitudinal direction of the back bar 8, via which washing liquid is conveyed to the vehicle window 12.
  • two wiper lips 13 are arranged parallel to one another and at a distance from one another, which have an essentially triangular cross section, which is already known from conventional wiper blades with only one wiper lip.
  • the wiper lips 13 are connected to the back bar 8 in such a way that in wiping operation they can assume an inclined position which is inclined forward with respect to the direction of movement B of the wiper strip 2 and which turns into the opposite inclined position when the direction of movement B of the wiper strip 2 is reversed. These inclined positions are defined so that the wiper lips 13 each with the edge lying in front in the direction of movement B, which thus forms a wiping edge 16, the vehicle Disc 12 sweeps.
  • An intensive cleaning element 17, which is formed by a bristle strip, is arranged in the distance between the two wiper lips 13. The intensive cleaning element 17 is fastened to the wall of the washing liquid channel 11 arranged in the back bar 8, which can elastically change its cross-sectional shape under the action of washing liquid conveyed.
  • the intensive cleaning element 17 is attached to a section of the wall of the washing liquid channel 11, which is caused by the pressure of the washing liquid in the direction of the vehicle window 12 to be cleaned and when the pressure of the washing liquid decreases due to elastic restoring forces of the wall of the washing liquid channel 11 is moved away from the vehicle window 12.
  • the washing liquid channel 11 is formed by an elastically deformable hose 18.
  • this hose 18 assumes a flat cross-sectional shape as shown in FIG.
  • the hose 18 is folded onto one another in such a way that the inner sides of the washing liquid channel 11 rest on one another or only leave a small gap between them.
  • This hose 18 is now arranged in a channel-like cavity 19 which extends longitudinally in the lower part of the back bar 8 which is constricted by the longitudinal grooves 9 and which is open between the two wiper lips 13 in the direction of the vehicle window 12.
  • the hose 18 is attached with its upper outer surface to the upper inner surface of the cavity 19, so that the attached to the back bar 8 Section of the tube 18 is kept dimensionally stable.
  • the intensive cleaning element 17 is attached to the lower section of the wall of the hose 18.

  • the intensive cleaning element 17 is thus guided or supported laterally within the opening 20.
  • the lower section of the hose 18, to which the intensive cleaning element 17 is directly attached has a plurality of dispensing openings 21 for washing liquid, which open directly into the intensive cleaning element 17. This means that pumped washing liquid passes through these discharge openings 21 into the intensive cleaning element 17 penetrated by cavities or channels and from there onto the vehicle window 12 to be cleaned.
  • FIG. 2 shows the wiper strip 2 in normal wiping operation.
  • This normal wiping operation takes place, for example, when the vehicle window 12 is to be cleared of rainwater and is only slightly contaminated in the process.
  • the vehicle window 12 is essentially wiped only by the wiping edges 16 of the two wiper lips 13.
  • the front wiper lip 13 in the direction of movement B is supported with its shoulder 22 located behind in the direction of movement B on the intensive cleaning element 17, which is thereby elastically deformed and in turn is supported on the front shoulder 23 of the rear wiper lip 13 supports.
  • the two wiper lips 13 could also be supported on the underside 15 of the back bar 8 with their rear shoulder in the direction of movement B without the intensive cleaning element 17 to be included in the support process. It should be taken into account here that when the direction of movement B of the wiper strip 2 is reversed, the shoulder 22 becomes the front shoulder and the shoulder 23 the rear shoulder.
  • FIG. 3 shows the wiper strip 2 when an intensive cleaning process is carried out.
  • the cross-sectional shape of the hose 18, which forms the washing liquid channel 11, has changed under the pressure of the washing liquid conveyed.
  • the tube 18 has been inflated and now fills the essentially oval cavity 19 in the back bar 8.
  • the lower area of the hose 18, to which the intensive cleaning element 17 is attached, has been moved in the direction of the vehicle window 12. As a result of this movement, the intensive cleaning element 17 has come into contact with the vehicle window 12.
  • washing liquid has reached the vehicle window 12 through the dispensing openings 21 and through the intensive cleaning element 17. From Fig. 3 it can be seen that during the intensive cleaning process, both the wiper lips 13 and the intensive cleaning element 17 contact the vehicle window 12.
  • the intensive cleaning element 17 with the additional action of washing liquid or cleaning agent concentrate or the like, which has been conveyed through the washing liquid channel 11, loosens or detaches heavy soiling of the vehicle window 12 and the immediately following wiper lip 13 immediately pushes this loosened or detached dirt outside the wiping field to be processed by the wiper blade. It is thereby achieved that the vehicle window 12 is not covered by the intensive cleaning element 17 by a view-impairing and thus dangerous film of dirt, as can happen with the wiper blade according to the prior art described at the outset, because there is no subsequent cleaning process there Wipe the vehicle windshield contacted.

It is thus achieved that in principle only this lower section 25 of the wall of the washing liquid channel 11, which extends essentially in the area between the tilting webs 14 of the two wiper lips 13, elastically deforms when pressure is applied by the washing liquid conveyed. The remaining parts of the wiper strip 2 are therefore not affected by the elastic deformation brought about by the pressure of the washing liquid, or are affected only to a negligible extent.
