  • the covering element can not become lost and a very simple handling is made possible on releasing the supply line(s) from the fluid connection.
  • the covering element is locked in its open position with the wiper blade or with the wiper arm.
  • the operating or respectively the removing of the supply line on the fluid connection of the wiper blade adapter is facilitated in so far as the covering element is secured in a position in which it does not disturb the releasing (and subsequent re-fastening) of the supply line on the fluid connection of the wiper blade adapter or respectively it is not necessary to hold the covering element manually in a corresponding position.
  • a hood-shaped construction the covering element ensures that the fluid connection completely protected by the covering element.
  • a hose guide body can be provided. The latter ensures that the at least one supply line is guided in a defined manner, without coming into contact or respectively conflict with other parts of the wiper blade adapter or of the wiper arm.
  • the hose guide body is constructed pivotably as part of the wiper blade adapter and is connected by a form or force fit with the wiper arm or respectively with the wiper arm adapter.
  • Such a construction or respectively fastening of the hose guide body makes possible a relatively simple production and mounting of the hose guide body on the wiper blade or respectively on the wiper arm adapter.
  • the fluid connection on the wiper blade side has at least one connection nozzle, which is arranged at least substantially perpendicularly to the longitudinal direction of the wiper blade and which is coupled with the supply line, which is constructed as a hose line.
  • the invention also comprises a wiper arm with a wiper blade according to the invention. Provision is made here that a covering element is arranged on the wiper arm for the freeing and covering at least of one fluid connection on the wiper blade adapter, wherein with the opened or removed covering element, the at least one supply line projects beyond the end of the wiper arm.
  • Fig. 1 a wiper blade according to the invention, fastened on a wiper arm, in perspective view,
  • Fig. 2 the wiper blade according to Fig. 1 and parts of the wiper arm in exploded illustration
  • Fig. 3 the wiper blade according to Fig. 1 a changeover position, in which the covering element which has been pivoted away frees supply lines, in perspective view.
  • Fig. 4 a perspective view onto a hose guide body, as is used in the wiper blade according to Fig. 1, and
  • Fig. 5 a section in the plane V-V of Fig. 4.
  • a wiper blade 10 according to the invention is illustrated for the cleaning of vehicle windows, in particular a windscreen of a road vehicle.
  • the wiper blade 10 is fastened exchangeably at the one end 2 of a wiper arm 1.
  • the wiper arm 1 consists in a known manner of a bearing element 3, able to be fastened on a wiper shaft of a windscreen wiper drive, and of a wiper rod 5, articulately connected with the bearing element 3 via a wiper arm joint 4, at the wiper arm end of which, facing away from the bearing element 3, the wiper blade 10 is fastened by means of a wiper blade adapter 11.
  • the two wiper blade sections 12, 13 have on their underside a mounting groove 18 for a wiper rubber 19 forming a wiper lip. Two spring strips 21 together with the wiper rubber 19 are also held in the mounting groove 18, wherein the spring strips 21 serve for reinforcing the wiper blade 10.
  • a closure cap 22, 23 is respectively arranged on the two front faces of the wiper blade 10.
  • a supply line 25 is provided on the vehicle side in the form of two hose lines 26, 27.

  • the wiper blade 10 With an installation of a new wiper blade 10, firstly the mechanical connection between the wiper blade 10 and the wiper arm 1 is produced. Then the two hose lines 26, 27 are pushed onto the connection nozzles 28, 29 of the (new) wiper blade adapter 11.
  • the wiper blade 10 has in addition a hose guide body 35 as component of the wiper blade adapter 11, which, as can be seen in particular with the aid of Fig. 4 and 5, has a guide section 36 onto which the two hose lines 26, 27 rest. It is further ensured, by lateral guides 37, 38, that the hose lines 26, 27 do not come in contact with or respectively touch e.g. the wiper blade adapter 11 at critical sites, so that the hose lines 26, 27 are arranged so as to be always protected mechanically inside the wiper blade adapter 11.
  • the hose guide body 35 consisting of plastic serves on the one hand for the pivotable mounting of the wiper blade adapter 11 on the wiper arm 1, and at the same time on the other hand for the connecting of the wiper blade 10 on the wiper arm 1.
  • the hose guide body 35 has, on the sides of the guides 37, 38 facing each other, in each case a guide pin 39, 40, which engages into a corresponding mounting opening 41, 42 (Fig. 2) of the wiper blade adapter 11, so that the hose guide body 35 is pivotable relative to the remaining wiper blade adapter 11.
