Definitions

  • the invention relates to a system comprising a wiper blade and a wiper arm, according to the preamble of independent claim 1.
  • a wiper blade is connected to a wiper arm via a wiper blade adapter to allow the wiper blade to be mounted on the vehicle and changed.
  • the purpose of the wiper blade adapter is to transmit the lateral guidance from the wiper arm to the wiper blade during the wiping movement.
  • a wiper blade adapter often allows for rotational movement to allow the wiper blade to accommodate the tilt and curvature of the window while wiping across the curvature of the window.
  • Two-part designs are known in which the wiper blade adapter includes a swivel joint, but also designs in which the connection to the wiper arm is made on an axis that allows rotation and can be detachably placed on the receiving elements of the wiper arm. In the latter embodiment, a pivot attached to the wiper arm is pushed laterally as an axis into a receiving opening of the wiper blade adapter.
  • Wiper blades are also known in the prior art, which have nozzles for applying a cleaning fluid to a windshield and in which fluid supply lines are routed through the wiper blade adapter or arranged on the wiper blade adapter to the wiper arm and can be releasably connected between the wiper arm and the wiper blade adapter.
  • US 2014331437 A1 discloses an arrangement for a windshield wiper system with a wiper blade adapter of a wiper blade that enables a rotary movement between a wiper arm and the wiper blade, the wiper blade adapter being set up to establish a hydraulic connection and an electrical connection of the wiper blade to a connection point of the to allow wiper arm.
  • the system comprising a wiper blade and a wiper arm, with the features of main claim 1 has the advantage that the connections for a cleaning fluid on the one hand and for electricity on the other hand are separated.
  • a flatter design can be made possible, since the relatively narrow width of the wiper blade and thus a wiper blade adapter, the supply connections for electricity and cleaning fluid can often only be arranged one above the other. Due to the separation, this can be done at different points and thus with a lower overall height.
  • a distance between connection points of the cleaning fluid or water and an electrical connection point is also advantageous. Liquid can escape from one side and there is always a risk with the electrical connection that there is no complete seal against moisture and water.
  • the result is advantageously easy assembly by the customer, who only has to attach the wiper arm and wiper blade at an angle to one another and can close the electrical power supply connection by twisting.
  • the wiper arm plug connection is advantageously arranged on a plug connection carrier which is connected to the wiper arm and is arranged on the wiper arm.
  • the plug-in connection carrier can be deformed elastically and as a result, rotational movements between the wiper blade and the wiper arm can be compensated for when wiping.
  • the wiper arm can be connected to the wiper blade via a pivot pin that can be inserted laterally into a receiving opening of the wiper blade adapter
  • a bridge reaching over the wiper blade adapter engages with an angled end behind the wiper blade adapter and secures the pivot pin.
  • the connector carrier is advantageously connected to the bridge.
  • connection connections for the cleaning fluid can be on the side of the cleaning fluid
  • the fluid line of the wiper arm can be elastic, in particular a hose line.
  • the wiper blade is advantageously a flat beam wiper blade with a support element that exerts a prestressing force in the direction of a pane, a wiper strip and a cover element that covers the support element on the upper side, with the cover element being able to have a spoiler.
  • the wiper blade adapter is connected to the support element and the power supply adapter is connected to the support element separately therefrom, in particular with a part of the cover element arranged in between.
  • Fig. 2 shows an exploded view of the elements of Fig. 1,
  • a wiper blade adapter 3 consisting of an upper part 4 and a lower part 5, which is connected to support elements of the wiper blade 1, is used to attach the wiper arm 2.
  • a cleaning fluid is supplied via the wiper arm 2 and is distributed by the wiper blade adapter 3 to a fluid line 7 in the wiper blade 1 which has nozzle openings for spraying cleaning fluid 8 .
  • the wiper blade 1 also has a cover element 9 in the form of a spoiler 10 .
  • a power supply adapter 12 is arranged on the wiper blade 1 separated by a part 11 of the cover element 9 and at a distance from the wiper blade adapter 3 .
  • An electrical heating element 24 prevents the water in a cleaning fluid from freezing at sub-zero temperatures.
  • the cover element 9 is placed on the support element 15 .
  • a part 11 of the cover element 9 is placed between the wiper blade adapter 3, consisting of the upper part 4 and lower part 5, and the power supply adapter 12 and separates them.
  • the fluid line 7 runs through the cover element 9, the lower part 5 and the power supply adapter 12, through the nozzle openings of which the cleaning fluid 8 can emerge.
  • the wiper arm 2 has a wiper arm plug connection 18 on a plug connection carrier 17 which can interact with the plug connection 13 on the upper side of the power supply adapter 12 .
  • the connector carrier 17 is arranged on a bridge 19 with an angled end 20 and laterally to the wiper arm 2. The angled end
  • FIG. 3 shows the wiper blade 1 with the wiper arm 2 attached for assembly.
  • a double fluid line 6 of the wiper arm 2 is aligned with its openings in this mounting position on connection connections 23 of the wiper blade adapter 3 .
  • FIG. 4 shows the wiper arm 2 in the assembly position relative to the wiper blade 1 . This can be secured, for example, by a latching lock.
  • FIG 5 shows the wiper arm 2 in the working position in relation to the wiper blade 1.
  • the wiper arm 2 is turned down onto the wiper blade 1 and the wiper arm plug connection 18 is connected to the plug connection 13 of the power supply adapter 12. Here, too, it can snap into place to secure it.
  • the wiper arm plug connection 18 is pressed down onto the plug connection 13 by the plug connection carrier 17 .

Abstract

L'invention concerne une lame d'essuyage comprenant un bras d'essuie-glace qui peuvent être reliés de manière amovible au moyen d'un adaptateur de lame d'essuyage (3) disposé sur la lame d'essuyage. Une conduite d'alimentation pour un liquide de nettoyage (8) peut être reliée au bras d'essuie-glace (2) par le biais de liaisons de raccordement (23) sur l'adaptateur de lame d'essuyage, et une liaison d'alimentation électrique est disposée de manière amovible entre la lame d'essuyage (1) et le bras d'essuie-glace (2). Selon l'invention, un adaptateur d'alimentation électrique (12) est disposé sur la lame d'essuyage (1) séparément de l'adaptateur de lame d'essuyage (3) et à une certaine distance de celui-ci, ledit adaptateur d'alimentation électrique comprenant une connexion à fiche (13) qui fait face au bras d'essuie-glace (2) et qui, avec une connexion à fiche de bras d'essuie-glace (18) disposée sur le bras d'essuie-glace (2), forme la liaison d'alimentation électrique, et la liaison d'alimentation électrique peut être fermée par rotation du bras d'essuie-glace (2) relativement à la lame d'essuyage (1) d'une position d'installation vers une position de travail.
