A wind deflector for a windscreen wiper system of a motor vehicle has a windscreen-cleaning apparatus with at least one nozzle for cleaning a windscreen integrated therein. The wind deflector has a wind deflector contour, by way of which an air flow in the region of an associated wiper arm and a wiper blade can be guided. The wind deflector, on its side that faces the wiper blade, has at least one wind-guiding element, which is arranged in the region of the associated nozzle and protrudes, raised, toward the windscreen.

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.

A windscreen wiper arm comprising a wiper arm member having a substantially U-shaped cross-section arranged to be pivotally connected to a mounting head mounted on a drive shaft, and a wiper rod having a first end rigidly connected to and extending inside said wiper arm member and a second end arranged to be connected to an elongated wiper blade to be placed in abutment with a windscreen to be wiped. The wiper arm includes a nozzle for spraying a washing liquid onto said windscreen to be wiped, where said nozzle is detachably connected to said wiper rod inside the U-shaped cross-section of the wiper arm member.

The invention proposes a system (10) for wiping a vehicle window (12), comprising: at least one windscreen wiper blade (14) adapted to be driven by a drive arm (16) of the wiper system (10) with alternating movements sweeping at least one portion of the exterior surface of a window to be wiped between two positions at which the sweeping direction is reversed; a device (18) for spraying a liquid onto the exterior surface; a pump for feeding the sprayer device (18) with liquid; a circuit (CP) for controlling the feeding of the sprayer device (18) by the pump (38) as a function of the sweeping direction, characterized in that it includes a sensor (CA) of acceleration of the windscreen wiper that is carried by the windscreen wiper and that is connected to the control circuit (CP) in order to supply to the control circuit (CP) signals representing the value of the acceleration of the windscreen wiper (11).

Disclosed is an arrangement of nozzle units for a wiper arm, wherein at least one nozzle unit comprises a rigid body, has a channel through which liquid can flow into the nozzle unit and/or out of the nozzle unit, and comprises a nozzle, which is connected to the channel. The nozzle units are in communication with each other in series such that a liquid can flow from a nozzle unit into a following nozzle unit in the series, wherein at least one nozzle unit has a contact surface which is formed such that the nozzle unit cannot rotate about the longitudinal axis thereof if the contact surface contacts a surface of a wiper arm. A wiper arm comprising the arrangement is also disclosed.

A wiper arm device for a wiper arm (20), having at least one fastening part (44) which is provided for connecting at least one articulation part (38) of the wiper arm (20) to a drive shaft (24) of a wiper drive (16), wherein the fastening part (44) has at least one fastening boss (46) for fastening the fastening part (44) to the drive shaft (24) and at least one articulation boss (48) for fastening the articulation part (38) to the fastening part (44).

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).
