A fluid guiding apparatus for a wiper arm of a windscreen wiper, the fluid guiding apparatus having a vehicle/arm interface in order to receive windscreen washing liquid from a source, an arm/wiper blade interface which has at least two fluid channels which are provided to supply the windscreen washing liquid to a wiper blade, at least a first and a second fluid line in order to guide the windscreen washing liquid from the vehicle/arm interface the arm/wiper blade interface and to provide it to one of the fluid channels in each case, and a heating wire which is guided at least through a portion of the first fluid line and at least through a portion of the second fluid line and which is provided to heat the windscreen washing liquid. The arm/wiper blade interface has a through-opening which connects the two fluid channels to each other. The heating wire is guided through the through-opening and the through-opening is closed with a sealing element.

Described is a windshield wiper apparatus that is formed to dispense fluid. The wiper apparatus includes an elongate body member having a length with a sealable channel therein that runs along the length. At least one blade protrudes downward along the length of the elongate body member. Further, a series of holes are formed such they pass from the sealable channel and through the elongate body member proximate the at least one blade. Thus, a fluid passing through the sealable channel is dispensed onto a surface proximate the at least one blade.

The invention relates to a wiper arm device, in particular a windscreen wiper arm device, comprising: at least one hose-holding unit (12) which can be mounted on at least one wiper arm (10) and which comprises at least one hose guide (14) provided for guiding at least one washing water hose (16); at least one auxiliary nozzle unit (18); and at least one coupling unit (20) which is provided to couple the auxiliary nozzle unit (18) to the hose-holding unit (12) and comprises at least one first coupling element (22) and at least one corresponding second coupling element (24) for coupling. According to the invention, the first coupling element (22) is formed at least in part by the hose guide (14).

A wiper arrangement having at least one securing and/or guide unit (34a; 34b; 34c), which has at least one securing element (36a; 36b; 36c) with which a connecting unit (24a; 24b; 24c) can be brought into contact when a wiper blade (14a; 14b; 14c) moves relative to a wiper arm (18a; 18b; 18c), and which has at least one guide element (44a; 44b; 44c), which guides the connecting unit (24a; 24b; 24c) when the wiper blade (14a; 14b; 14c) moves relative to the wiper arm (18a; 18b; 18c).

The invention relates to a wiper blade device, in particular a windscreen wiper blade device, comprising: at least one wiper blade (10); at least one adapter unit (12) for coupling the wiper blade (10) to a wiper arm (14) of a wiper (16), in particular a windscreen wiper; at least one spraying unit (18) integrated in the wiper blade (10); and at least one washing water distributor unit (20) for supplying washing water to the spraying unit (18), in particular to nozzle elements (22) of the spraying unit (18) which are arranged substantially parallel to a main extension direction (54) of the wiper blade (10) along the wiper blade (10), wherein the washing water distributor unit (20) has at least one channel coupling element (24) for coupling at least one portion of the washing water distributor unit (20) to a washing water channel (26) of the spraying unit (18), the coupling being provided in particular for passage of a fluid and being preferably fluid-tight, and wherein the washing water distributor unit (20) has at least one adapter coupling element (28) for coupling at least one additional portion of the washing water distributor unit (20) to an additional washing water channel (30) of the adapter unit (12), the coupling being provided in particular for passage of a fluid and being preferably fluid-tight.
