Definitions

  • the invention relates to a wiper blade according to the preamble of the independent claims.
  • the support element thus replaces the complex mounting bracket construction with two arranged in the wiper strip spring rails, as practiced in conventional wiper blades (DE-OS 15 05 397), because the support element in addition to the distribution of the contact pressure also causes the necessary transverse reinforcement of the rubber-elastic wiper strip.
  • the wiper blade namely the force exerted by a wiper arm on a main bar, directed to the disc bearing force is transmitted to two claw straps and distributed by these four claws on the rubber-elastic wiper strip.
  • the support element has a spring elasticity in the direction of the vehicle windows and a certain flexural rigidity in the direction of the wiping movement.
  • the wiping sheet In working position, the wiping sheet is loaded in the direction of the vehicle window through the contact force of the wiper arm, wherein the wiper lip rests against the vehicle window.
  • a wiper strip is known from DE 9104461.8 U1, in which a damping strip is provided between the wiper strip back and the abutting shoulder of the reversing wedge.
  • the shoulder first strikes against the damping strip and presses it until it touches the wiper strip back.
  • this damping is not always sufficient. Especially with very long wiper blades that works
  • the wiper blade with the features of the main claim has the advantage that the lateral arranged by the tilting web additional webs the Umlegevorgang continuously attenuate by exerting on the reversing wedge with increasing inclination an increased compressive force on one side or an increased tensile force on the other side.
  • This is on the one hand, as desired, prevents the shoulder of the Umlegkeils at full speed against the shoulder of the wiper strip back bouncing, whereby the disturbing Umklappgehoffsch can be effectively prevented, on the other hand causes the constant force on the Umlegkeil located in the towing position that the transfer as such takes place safely at the point of inflection.
  • wiper blades which have been exposed to environmental influences for a long time, problems can occasionally occur here.
  • the hardness of the wiper blade rubber of less than 64 Shore can be selected by the use of the webs. With this hardness, a significant reduction in subjective noise perception already occurs in connection with the webs, the wiper strip remains in its mechanical values in the areas which ensure a long service life. Compared to comparable wiper strips without webs and slightly greater hardness can u. U. even a life extension can be expected. If the hardness is between 50 and 60 Shore, further noise reduction is possible without noticeably reducing the lifetime.
  • Another way to reduce the folding noise is to vary the distance of the webs to each other along the wiper blade.
  • it is advantageous if, in the region of high forces, that is to say in the region of the terminal Direction of the web density higher, the distance is therefore less than in the region of at least one end of the wiper blade.
  • the mechanical stability of the wiper blade is rather improved and still reduces the Umklappge Hursch.
  • the connection device is arranged in a central region of the wiper blade, it is thus advisable to increase the distance from this central region to the ends of the wiper blade.
  • the volume of the Umklappgegiesches can be influenced.
  • the squeegee consists essentially of polychloroprene. Even if the squeegee contains at least one of the substances EPDM, CR or natural rubber, the folding noise can subjectively be reduced subjectively.
  • FIG. 1 shows a wiper blade according to the invention in perspective
  • FIG. 2 shows a wiper strip enlarged with respect to FIG. 1 with an indicated support element
  • FIG. 3 shows a section along the line III-III in FIG. 2
  • FIG. 4 shows a variant according to FIG. 3,
  • FIG. 5 shows a view along the arrow V in FIG. 2,
  • FIG. 6 shows a variant of the detail VI in FIG. 5
  • FIGS. 7 and 8 variants for FIG. 6 and FIG. 9 further variants for FIG. 1. Description of the embodiments

  • An elongated, rubber-elastic wiper strip 24, which extends longitudinally parallel to the support element 12, is arranged on the concave lower or inner band surface or band side 22 of the curved support element 12 facing the disc.

  • the wiper arm 20 and thus also the wiper blade 10 are loaded in the direction of the arrow 26 to be wiped disc, whose surface to be wiped is indicated in Fig. 1 by the dotted line 14. Since the dot-dash line is intended to represent the strongest curvature of the disk surface, it is clearly evident that the curvature of the still unloaded wiper blade 10 resting against the disk 14 with its ends 10 'is greater than the maximum disk curvature. It has - unloaded - so with respect to the disc a concave course. Under the contact pressure (arrow 26), the wiper blade 10 sets with his
  • the wiper strip 24 shown in Figure 2 has a wiper strip back 34 which is connected via a tilting ridge 36 with a Umlegkeil 38, on the underside of the wiper lip 28 is arranged. Laterally of the tilting ridge 36 extend two longitudinal grooves 40, the upper side of the wiper strip back 34 and the underside of the Umlegkeil 38 are formed. Within the longitudinal grooves 40, distributed over the length of the longitudinal grooves 40, webs 42 provided, which are arranged laterally of the tilting web 36.
  • Each web 42 extends from the tilting web 36 starting laterally toward the open side of the longitudinal groove 40 and connects the wiper strip back 34 with the Umlegkeil 38.
  • the webs 42 are part of the wiper strip 24 and therefore stoffschlüs- sig with the wiper strip back 34, the tilting bar 36 and the Umlegkeil 38 connected.
  • a soft squeegee is selected as the material for the wiper strip 24.
  • the hardness of squeegees are specified in the unit Shore, whose dimension is in principle an equivalent for a penetration of a standard body into the surface of the squeegee at a certain force.
  • Conventional wiping gums have hardnesses greater than 64 shore.
  • the squeegee has a hardness of 56 Shore, with which a reduction of the Umklappge Hurschs is achieved on a sixteenth of the housing without webs and with harder squeegee.
  • each web 42 extends perpendicularly from the tilting web 36 to the tilting web 36. Furthermore, it can be seen that the webs 42 are arranged on both sides of the tilting web 36. If the webs 42 of FIG. 3 are aligned on both sides of the tilting web 36, FIG. 4 shows the webs
  • the distance a of the webs 42 to each other should be between 10 mm and 50 mm and is preferably 20 mm. In the case of the staggered webs 42 of Figure 4 then results in a distance of 10 mm, if the
  • Webs 42 viewed on both sides of the tilting ridge 36. Over the length of the wiper strip 24, the webs 42 are evenly distributed. However, it is also conceivable, for. B. for reasons of resonance, the distance a over the length of the wiper strip 24 to vary.
  • the distance a varies such that in the middle region of the wiper blade, that is to say in the region of the connecting device 18, the distance is smaller and increases towards the ends of the wiper blade 10.
  • the distance al is smaller than the distance a2, this smaller than the distance a3 and this in turn smaller than the distance a4.
  • the number of webs is not limited to the number shown in the embodiment, but also depends in particular on the length of the wiper blades.
  • the squeegee of the wiper strip 24 is in the embodiments substantially of polychloroprene. However, it can also contain one of the substances EPDM, CR or natural rubber.
  • the tilting bridge 36 represents the actual operative connection between the wiper strip back 34 and the Umlegkeil 38 and must be dimensioned accordingly.
  • the webs 42 are kept smaller in thickness d than the thickness D of the tilting web 36. In a preferred embodiment, the thickness d of the webs 42 is half the thickness D of the tilting web 36.
  • the webs 42 form a connection between the wiper strip back 34 and the Umlegkeil 38 and extend from the tilting ridge 36 to each open side of the longitudinal grooves 40. It is clear that it makes sense for manufacturing reasons, the webs 42 with the Kippsteg 36 to connect. It would also be conceivable, however, to leave a gap between the webs 42 and the tilting web 36. The situation is similar with the open sides of the longitudinal grooves 40.
  • the webs 42 connect an outer edge 44 of the wiper strip back 34 in a straight line 45 with an outer edge 46 of the Umlegkeils 38, as shown in Figure 5.
  • connection of the two outer edges 44 and 46 is formed in the shape of a groove 48, which has the advantage of a low notch effect.
  • the example shown in Figure 7 is one of three variants.
  • the outer sides 50 of the webs 42 extend obliquely and are connected to only one of the outer edges 44 or 46. In this case, it is possible for all the webs 42 to extend obliquely from the outer edge 44 or from the outer edge 46 into the longitudinal groove 40 or alternatively in alternation from the outer edge 44 or the outer edge 46.
  • the outsides 52 are each
  • Bridge 42 in the respective longitudinal groove 40 is added. Consequently, they do not touch any of the outer edges 44 or 46.
  • the goal of reducing or even minimizing the flip-over noise of the wiper blade 10 is achieved with each of the variants according to FIGS. 5 to 8.
  • the spring characteristic to be assigned to the webs 42 can be strongly influenced by the shape of the outside. For example, it can be made steeper or shallower or have a degressive or progressive course. It is also conceivable to different shapes of the outer sides of the webs 42 to each other combine. This can be done at successive webs 42 or within a web 42 at its outer edge.
  • FIG. 9 shows that the webs 42 are respectively formed on only one side 54 or 56, but on the opposite side 56 or 54 only rest or even have a small spacing.
  • the training can also be made so that successive webs 42 are integrally formed on its upper side 54 and on its lower side 56 and free on the opposite side. In this way it is possible that, although a pressure force is exerted on the Umlegkeil 38 by the webs 42, starting from the wiper strip back 34, but a tensile force is omitted.
