Definitions

  • the present invention relates to a windscreen wiper device comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, wherein said wiper blade comprises a first part including a central longitudinal groove, in which groove a longitudinal strip of the carrier element is disposed, and wherein said wiper blade comprises a second part including a wiping element which can be placed in abutment with a windscreen to be wiped, which windscreen wiper device comprises a connecting device for an oscillating arm, wherein said oscillating arm is pivotally connected to said connecting device about a pivot axis near one end thereof.
  • Such a windscreen wiper device is generally known.
  • This prior art windscreen wiper device is designed as a so-called “flat blade” or “yokeless blade”, wherein no use is made of several yokes pivotally connected to each other, but wherein the wiper blade is biassed by the carrier element, as a result of which it exhibits a specific curvature.
  • the object of the invention is to provide an improved windscreen wiper device.
  • a windscreen wiper device of the type referred to in the introduction is characterized according to the invention in that said wiping element, during its oscillatory movement, is hingeable along at least one hinge positioned at a distance from a location where said wiping element abuts said first part of said wiper blade.
  • An important aspect of the invention is that, during oscillatory movement of said wiping element, forces involved therewith are exerted on said strong first part instead of on said weaker hinge like in the prior art.
  • said wiper blade and said wiping element are made in one piece of elastomeric material.
  • said wiping element abuts said first part of said wiper blade along a rolling contact surface.
  • said wiping element abuts said
  • said wiping element permanently abuts said strong longitudinal strip, wherein said wiping element performs a rolling movement along said rolling contact surface during its oscillatory movement.
  • said wiping element consists of a downwardly extending wiping lip and an upwardly extending protrusion abutting said longitudinal strip.
  • Said protrusion particularly has a round contact surface abutting said longitudinal strip, so that said rolling contact surface is formed by said round contact surface.
  • said wiping element is hingeable along at least two hinges positioned on opposite sides of said wiping element, and wherein said location where said wiping element abuts said first part of said wiper blade extends between said hinges.
  • said hinges are part of bottom of said groove and form an
  • said hinges are resilient in order to allow oscillatory movement of said wiping element and to limit a reversal movement of said wiping element during its oscillatory movement.
  • said wiper blade is provided with a spoiler at a side thereof facing away from a windscreen to be wiped.
  • figure 1 is a perspective, schematic view of a
  • figure 2 shows a cross-sectional view of a wiper blade as used in a windscreen wiper device of figure 1.
  • FIG. 1 shows a preferred variant of a windscreen wiper device 1 according to the invention.
  • Said windscreen wiper device is built up of an elastomeric wiper blade 2
  • the windscreen wiper device 1 is furthermore built up of a connecting device 6 for connecting an
  • the oscillating wiper arm 7 is pivotally connected to the connecting device 6 about a pivot axis near one end.
  • the preferred embodiment of figure 1 according to the invention comprises a spoiler or "air deflector" 8 which is made in one piece with the rubber wiper blade 2 and which extends along the entire length thereof.
  • the connecting device 6 with the wiper blade 2 is mounted onto the oscillating arm 7 as follows. A joint part 9 being already clipped onto the connecting device 6 is pivoted relative to the connecting device 6, so that said joint part 9 can be easily slided on a free end of the oscillating arm 7.
  • the connecting device 6 comprises two cylindrical protrusions 12 extending outwards on either side of said connecting device 6.
  • protrusions 12 pivotally engage in identically shaped cylindrical recesses 13 of the plastic joint part 9. Said protrusions 12 act as bearing surfaces at the location of the pivot axis in order to pivot the joint part 9 (and the oscillating arm 7 attached thereto) about the pivot axis near one end of the oscillating arm 7.
  • said oscillating arm 7 is connected to a mounting head fixed for rotation to a shaft driven by a small motor. In use, the shaft rotates alternately in a clockwise and in a counter-clockwise sense carrying the mounting head into rotation also, which in turn draws said oscillating arm 7 into rotation and by means of said connecting device 6 moves said wiper blade 2.
  • the wiper blade 2 comprises a wiping element 14 made in once piece therewith and forming part of a bottom of said groove 3.
  • Said wiping element 14 consists of a downwardly extending wiping lip 15 and an upwardly extending protrusion 16 abutting said longitudinal strip 4.
  • Said protrusion 16 has a round contact surface abutting said longitudinal strip 4, so that said wiping element 14 during its oscillatory movement carries out a rolling movement along a rolling contact surface 17 formed by said round contact surface.
  • Said wiping lip 15 rests with its free end on a windscreen to be wiped. In action said wiping lip 15, as if it were a hinge, tilts in its
  • said wiping element 14 is hingeable along at least two hinges 18,19 positioned on opposite sides of said wiping element 14, and wherein said rolling contact surface where said wiping element 14 abuts said longitudinal strip 4 is positioned between said hinges 18,19.
  • Said hinges 18,19 are thus spaced apart from said rolling contact surface 17, so that forces are exerted on said strong longitudinal strip 4 instead of on said weaker hinge like in the prior art.
  • Said hinges 18,19 are resilient in order to allow oscillatory movement of said wiping element 14 and to limit/damp a reversal movement of said wiping element 14 during its oscillatory movement for reducing the so-called "reversal noise".
  • said central groove 3 extends in upward direction above the longitudinal strip 4 for forming a longitudinal hollow channel 20 defined by said
