A wiper arm spoiler device having a base member (10a; 10b), having a wind deflector unit (12a; 12b) which is arranged on the base member (10a; 10b) and which has at least one wind deflector element (14a; 14b), having a coupling unit (16a; 16b) which is provided to couple the wind deflector unit (12a; 12b) to a wiper rod (18a; 18b) of a wiper arm (20a; 20b). The wiper arm spoiler device has at least one washing water channel (24a; 24b, 26b).

A wiper blade (10), in particular for a motor vehicle, is proposed. It comprises a wiper bar (12) and a coupling element (14) which comprises a coupling connection piece (26) for coupling a fluid channel (22). The coupling connection piece (22) is constructed to be at least partially flexible.

A surface wiper device which includes a carrier which supports a blade. The carrier attaches to a wiper arm which urges the blade against and moves the blade across the surface of a windshield. The carrier further provides a plurality of outlets each of which communicate between a hollow passage inside the carrier and a location on the external surface of the carrier. A fluid can be delivered from a fluid source fluidicly coupled to the hollow passage of the carrier under sufficient pressure to be dispersed from the plurality of outlets onto the windshield during movement of the blade. A fluid heater can be thermally coupled with the fluid delivered from the fluid source to the plurality of outlets to increase the temperature of the fluid dispersed onto the windshield. The fluid can be sufficiently heated to generate a heated gas.

The invention relates to a device (1) for de-icing and/or cleaning insects off a vehicle window (10) which is designed to perform at least a window wiping function and comprising a continuous-rotation motor (40) designed to drive the rotation of at least one wiper (30) to at least a first level corresponding to a first wiping speed, referred to as high wiping speed (HWS), and a second level at a second wiping speed, referred to as low wiping speed (LWS) and lower than the first, so as to perform the wiping function, and a system for spraying a specific, de-icing or insect-cleaning liquid, onto the window (10) from the said at least one wiper (30), characterized in that the continuous-rotation motor is designed in such a way as to operate at a third speed (CS), lower than the second speed, and in that the device is configured to cause the said wiper (30) to at least descend from the high position (PH) as far as the low position (PB) with the motor (40) operating at the very slow speed (CS) and with the said spraying system activated over at least part of the said descent. The invention also relates to the continuous-rotation motor suited to the device and to a cleaning method using the device.

A wiper including wiper bracket which couples a wiper arm to blade carrier which carries one or more blades and includes an internal flow path which conducts fluid from a wiper bracket inlet through a hollow passage in a wiper blade carrier cover to plurality of outlets aligned with passthroughs in the blade carrier through which fluid egresses from the wiper.

A wiper device having a wiper arm and a wiper blade device, wherein the wiper blade device has a wiper strip, a spoiler, and a wiper blade, and wherein the wiper blade device furthermore has an adapter with a fluid inlet and two fluid outlets to conduct fluid into fluid channels of the spoiler. The adapter is of multi-part design such that the adapter has a first part, which has the fluid inlet, a first outlet region and a second outlet region. The first part furthermore has a deflection geometry for conducting a fluid entering the fluid inlet to the first outlet region and the second outlet region. The adapter furthermore has a second part and a third part, wherein the second part closes the first outlet region and has the first fluid outlet, and wherein the third part closes the second outlet region and has the second fluid outlet.

A wiper device (10) having a wiper arm adapter (16) and having a cover unit (30) which is mounted on the wiper arm adapter (16) so as to be pivotable about a pivot axis (36) between an open position (34) and a closed position (32) and which, in the closed position (32), at least partially covers the wiper arm adapter (16) in relation to an environment. The cover unit (30), in the closed position (32), is displaceable translationally between an unlocked position (38) and a locked position (40).

A micro-sized structure and construction method for a fluidic oscillator wash or spray nozzle (100 or 250) has a nozzle housing (110 or 252) enclosing an interior cavity (112 or 262) which receives an insert (114 or 254) having internal fluid passages defining first and second power nozzles (120, 122 or 280, 282). The power nozzles receive pressurized fluid (130) flowing through the interior cavity of the housing, where the fluid flows into the cavity at the bottom of the housing and flows upwardly to inlets (140, 142) for the power nozzles so that accelerating first and second fluid flows are aimed by the power nozzles toward one another in an interaction region (154 or 284) which exhausts laterally along a spray axis through a horn-shaped throat defined partly within the insert and partly within the flared spray outlet orifice (160 or 290) defined through the sidewall (162) in the housing.

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).
