Definitions

  • the invention is based on a wiper blade in flat bar construction according to the preamble of claim 1.
  • the wiper strip consists of an elastomeric material and has a spoiler on its upper side.
  • This can be directly molded and made of the same material as the wiper strip or be made as a separate component made of a suitable plastic.
  • the spoiler can serve alone or together with one or more spring rails as a supporting element of the wiper blade.
  • the guide surfaces extend in the longitudinal direction of the wiper blade and connect with a small heel to the baffle of the spoiler. Due to the baffles of the spoiler and the end caps of the wind blow increasingly pressed the wiper blade against the vehicle window when it flows against the wiper blade substantially transverse to the longitudinal direction.
  • the guide surface of the end cap extends at the outer end of the wiper blade transversely to the longitudinal direction of the wiper blade and is bent away from the vehicle window, so that the distance of the guide surface increases from the vehicle window in the longitudinal direction of the wiper blade to the outer end.
  • the guide surface of the end cap has at least one stowage wall extending transversely to the longitudinal direction.
  • the rainwater flows through the airstream during the upward movement in the longitudinal direction on the wiper blade, in particular the spoiler along the outer end of the wiper blade and is thrown in the downward movement in the adjacent wiping field, z. B. from the driver side wiper blade in the passenger side field of view. This is disturbing, especially if in abundance windscreen cleaner z. B. be used in the form of soaps.

  • a front wall curved convexly toward the outer end of the wiper blade serves as a stowage wall and forms a storage space open longitudinally to the center of the wiper blade with a guide surface of the end cap and a side wall opposite the guide surface.
  • water can collect during the downward movement, which can flow off during the subsequent upward movement.
  • a second stowage wall in the form of a prewall may be provided parallel to the first stowage wall in the longitudinal direction toward the center of the wiper blade, wherein a stagnation chamber is located between the first stowage wall and the prewall. The pretext stops the flow, whereby the transgressing water gets into the stagnation chamber and flows off from there with a great deal of delay.
  • the present invention relates to both a wiper blade with mounted end caps and the end cap for the outer end of the wiper blade itself, provided that it has features of at least one claim of the claims relating to the wiper blade.
  • FIG. 1 is a perspective view of a wiper blade according to the invention

  • a spoiler 14 is provided on both sides of the connecting element 12. This can be carried out continuously in one piece or in two parts.
  • the spoiler 14 comprises with guide profiles 28 spring rails made of spring steel or plastic, through the guide profiles 28th are covered.
  • the spring rails serve as a resilient support member for a wiper strip 24, wherein the support member is concave pre-curved toward the wiper strip 24 in order to achieve a desired distribution of the contact pressure over the length of the wiper strip 24.

  • the end caps 20, 22 comprise the end of the spoiler 14 with a profile corresponding to the spoiler 14, in particular, the guide surface 26 of the spoiler 14 is followed by a corresponding guide surface 34 of the end cap 22.
  • the crest of the end cap is designated 36.
  • the end cap 22 is guided by a guide profile 32 on the guide section 28 of the spoiler 14 and fixed in the longitudinal direction. At the transition between the end cap 22 and the
  • Spoiler 14 results in a step 38, which is essentially due to the material thickness of the end cap 22.
  • the end cap 22 at the outer end 18 of the wiper blade 10 has a transverse to the longitudinal direction Stauwand 40, which also forms the outwardly facing end wall of the end cap 22.
  • Stauwand 40 which also forms the outwardly facing end wall of the end cap 22.
  • the longitudinal direction of the wiper blade 10 assumes a different angular position to the direction of the wind, at the beginning of the downward movement of the wiper blade 10 in the rule of the wind in the longitudinal direction of the wiper blade 10 flows and adhering to the spoiler 14 rainwater to the outer end 18 of the wiper blade 10 drives. This effect is supported by the centrifugal forces.
  • the rainwater is stopped by the baffle 40 at the outer end of the end cap 22 and deflected upward so that the wind can atomize the water and blow on the vehicle roof.
  • FIG. 4 and FIG. 5 differs from the embodiment of FIG. 2 and FIG. 3 in that the baffle 40, which forms the end wall of the cap 22, has a projection 42 which in the direction of the wiper strip 24 for Vehicle window is directed and the wiper strip 24 frontally at least partially covers.
  • the water transported in the longitudinal direction of the wiper strip 24 water slides in the direction of the vehicle window by the projection 42, so that it does not get into the field of view of the adjacent wiping field.
  • a stowage wall 46 is arranged a distance far from the center of the wiper blade 10 transversely to the guide surface 34 of the end cap 52.
  • FIG. 8 shows an embodiment of the end cap 52 with a projection 42 on the
  • End wall 48 which covers the wiper strip 24 frontally at least partially. It goes without saying that the projection 42 can also be provided in the case of the following end caps according to FIGS. 7 to 12, without being particularly pointed out below.
  • the embodiment according to FIG. 9 and FIG. 10 differs from the embodiment according to FIG. 6 and FIG. 7 in that with an end cap 56 the stowage wall 46 is omitted and thereby the end wall 48 serves as a stowage wall, wherein between the end wall 48 and the Leitfiumblee 34 and the guide surface 34 effectivelyo- the side wall 50, a storage space 54 is formed, which serves to calm the flow, whereby the change in direction of rainwater flow is favored at the spoiler 14.
  • the embodiment of the end cap 58 according to FIG. 1 1 and FIG. 12 differs from the embodiment of the end cap 22 according to FIGS. 2 and 3 in that, in addition to the stowage wall 40 provided at the outer end of the end cap 22, a further stowage wall in the form of a pretext 60 is arranged, which runs parallel to the first stowage wall 40 and a distance to the center of the wiper blade 10 is offset. Between the first stowage wall 40 and the front wall 60 there is a stowage space 62, in which the rainwater passing over the front wall 60 is collected, calmed and deflected.
