DETAILED DESCRIPTION

[0043] A wiper arrangement 10 which is provided for a vehicle, for example for a motor vehicle, is shown in FIG. 1. The wiper arrangement 10 has a wiper arm 12 and a wiper blade device 14. The wiper arm 12 is pivotably fixable at a first end 16 to the motor vehicle. Electrical connectors 18 which enable, for example, a heating of the wiper arm 12 or the wiper blade device 14 are also shown at the first end 16. It is also shown that the wiper blade device 14 is fixed at a second end 20 of the wiper arm 12.

[0044] The wiper blade device 14 is shown in the further figures in detail and in various embodiments.

[0045] For example, it is shown in FIG. 2 that the wiper blade device 14 comprises a wiper blade 22 and a carrier 24. The wiper blade 22 is fixed to the carrier 24. The carrier 24 can also serve to connect the wiper blade device 14 on its carrier 24 mechanically to the wiper arm 12.

[0046] In order to permit spraying cleaning liquid onto a pane of the vehicle, it is provided that the wiper blade device 14 has a liquid-discharging system 26 comprising at least one liquid-discharging channel, not shown in detail, wherein the liquid-discharging channel also has discharge openings, not shown in detail, for discharging cleaning liquid from the liquid-discharging channel onto a pane of the vehicle.

[0047] At least one adapter 28 for hydraulically connecting a liquid supply 30 to the liquid-discharging system is also fixed to the carrier 24. Two adapters 28 which are connected to the liquid supply 30 are shown in detail in FIG. 2. The adapters 28 have in each case a liquid inlet 32 which is configured as a male connector. The liquid supply 30 also comprises a hose 34, in the embodiment according to FIG. 2 two hoses 34, which are connected to a reservoir, such as for example a tank, for cleaning liquid.

[0048] The adapters 28 are connected via a latching connection to a housing 36 by latching means 37, wherein the housing 36 in turn is connected via a latching connection by latching means 39 to the carrier 24. It can be seen that a common housing 36 is provided for both adapters 28. The region of the adapters 28 and the housing 36 can be covered by a housing flap 23, as is shown in FIG. 1.

[0049] In the embodiment according to FIG. 2, it is also provided that the wiper blade device 14 is designed for the two-sided discharge of cleaning liquid and has two adapters 28, each of the adapters 28 having exactly one liquid outlet 38 for connecting the adapter 28 and thus the liquid supply 30 to one or more liquid-discharging channels through which cleaning liquid can be discharged on one side and on the same side of the wiper blade 22. The adapters 28 are thus individual components and separated from one another, but in principle can be designed so as to correspond to one another, as a mirror-image of one another or differently from one another.

[0050] In principle, it is thus provided that each of one or more adapters 28 arranged on the carrier 24 is designed to connect the liquid supply 30 only to one or more such liquid-discharging channels of the liquid-discharging system 26 through which cleaning liquid can be discharged on one side and on the same side of the wiper blade 22.

[0051] This is also shown in FIG. 5, for example, in which a wiper blade device 14 which is designed for the one-sided discharge of cleaning liquid is shown. In this embodiment, the wiper blade device 14 has exactly one adapter 28 which has exactly one liquid outlet 38 for connecting the adapter 28 and thus the liquid supply 30 to one or more liquid-discharging channels through which cleaning liquid can be discharged on one side and on the same side of the wiper blade 22.

[0052] It can be identified in the embodiment according to FIG. 5 that an adapter 28 can be dispensed with, due to the spray functionality on only one side, in contrast to the embodiment of FIG. 2.

[0053] An electrical connector 40 which can be connected, for example, to the electrical connectors 18 on the wiper arm 12 is also shown in FIGS. 2 and 5. These electrical connectors can permit a heating system, not shown in detail, to be activated via electrical lines 42, so that the wiper arm 12 and/or optionally the liquid supply 30 and equally the liquid-discharging system 26, such as for example the channels in the wiper blade 12, can be heated.

[0054] The further figures, however, show further corresponding embodiments of a wiper blade device, as set forth hereinafter, wherein in particular the differences are described.

[0055] In FIG. 3 in turn an embodiment is shown in which the wiper blade device 14 is provided for a two-sided spraying of the cleaning liquid. It is provided by corresponding electrical lines 42 that only the liquid-discharging system 26, but not the wiper arm 12, can be heated.

[0056] FIGS. 4 and 6 show embodiments without a heating system, wherein in FIG. 4 the wiper blade device 14 is provided for a two-sided spraying of the cleaning liquid and wherein in FIG. 6 the wiper blade device 14 is provided for a one-sided spraying of the cleaning liquid. Accordingly, an electrical connector can be dispensed with.

[0057] In principle, however, in the corresponding embodiments of FIGS. 2 and 5 and 4 and 6 it can be shown that a cost-effective and adaptable solution which permits an unlimited functionality is provided by the modular construction of the wiper blade device 14 according to the invention.
