Definitions

  • Wiper blade especially flat wiper blade
  • the invention relates to a wiper blade, in particular a flat wiper blade for a vehicle, for arrangement on a drivable wiper arm, with at least one elongated support element made of a flexible material, with a wiper rubber that can be placed on the support element and that comprises a wiper strip facing the window to be wiped , And with arranged at the free ends of the squeegee or the support member end members.

  • the support element is designed in the form of a spring rail.
  • the wiper rubber then preferably has a receptacle for the one spring rail, which extends in the longitudinal direction of the wiper blade.
  • the support element is pre-bent in the unloaded state, ie if the wiper blade is not in contact with the window. With flat wiper blades, the support element replaces the complex and, in particular, high-build weighing beam Support bracket construction, as is known from the prior art.
  • the present invention is therefore based on the object of providing a wiper blade in which lifting off of the free ends of the wiper blade is counteracted.
  • the end elements known from the known prior art serve primarily for fastening the wiper rubber in the longitudinal direction of the wiper blade.
  • the end elements In the case of a wiper blade with a support element in the form of two spring rails arranged parallel to one another, the end elements also ensure the spacing of the spring rails from one another. Furthermore, the end elements prevent a risk of injury at the free ends of the wiper blade and the support element.
  • the wiper blade according to the invention ensures, due to the special design of the end elements, that the free ends of the wiper blade during of the wiping process with an increased pressing force against the window to be wiped. This has the advantage that lifting off the free ends of the wiper blade or the wiper rubber is counteracted in particular at higher vehicle speeds.
  • the free ends of the wiper blade can follow the window curvature and that the wiper rubber and associated wiper strip lie against the window to be wiped over the entire wiper angle in the region of the free ends of the wiper blade.

  • the flow profile is designed such that the contact pressure at the end of the wiper blade equipped with the end element is increased mainly when the wind flows in transversely to the wiper blade.
  • the wiper blade With a spoiler-like approach over its entire longitudinal direction, which causes the wiper blade to be applied largely uniformly over its entire length with an increased contact force when it is positioned transversely to the oncoming wind.
  • the wiper blade When the wiper blade is positioned lengthways to the direction of travel, the known, spoiler-like approach loses a large part of its effect.

  • a further embodiment of the invention is characterized in that the flow profile is designed with an egg-like shape in the wiper blade transverse and / or longitudinal direction of the wiper blade. It has been shown that a wiper blade with at least one end element, the flow profile of which has such an egg-like shape, has particularly good aerodynamic properties.

  • the flow profile is designed as a hollow profile.
  • a hollow profile can have the particular advantage that the end element has a relatively low air resistance when there is an inflow in a given direction and a relatively high air flow when there is an inflow in another direction.
  • the flow profile can be embodied as a hollow profile that extends in a tube-like manner in the transverse direction of the wiper blade.
  • This has the advantage that the hollow profile has a low air resistance when the flow is transverse to the longitudinal direction of the wiper blade and a relatively high air flow when the flow is in the longitudinal direction of the wiper blade.

  • the wiper blade is subjected to no or only a slight, additionally increased pressing force via the flow profile.
  • the longitudinal direction of the wiper blade is largely flush with the lower edge of the section of the wiper rubber on which the wiper strip is molded. The consequence of this is that no undesirable air turbulence can occur between the end element and the window to be wiped. Such undesirable air turbulence can result in the water wiped off the wiper strip coming back into the wiping field in an uncontrolled manner or being sprayed.
  • the area of the flow profile further away from the wiper blade in the longitudinal direction of the wiper blade is designed to be wider than the area closer to the wiper blade.
  • the end element has spoiler-like extension extending in the longitudinal direction of the wiper blade, the end element having an area which receives the spoiler-shaped extension and merges into the flow profile. This ensures that a harmonious transition between the area receiving the spoiler-like approach and the flow profile is achieved. It also ensures that the effects of the spoiler-like approach and the flow profile of the end element do not interfere with each other. A synergetic effect can advantageously be achieved here.
