The invention relates to a wiper device (100) for cleaning vehicle windows, with a wiper arm (10; 10a-10d) and a wiper blade (1) able to be fastened to the wiper arm (10; 10a-10d), with a cleaning arrangement (40; 40a-40d) having at least one first spray nozzle (42, 43) for spraying a washing fluid, wherein the cleaning arrangement (40; 40a-40d) is connected directly with the wiper arm (10; 10a-10d), and with a fastening arrangement (2) for connecting the wiper blade (1) with the wiper arm (10; 10a-10d), wherein the cleaning arrangement (40; 40a-40d) is constructed as a separate component from the fastening arrangement (2) for the wiper blade (1).

When an operation signal of a view-obstructing material removal mode switch has been detected, a controller controls such that wiping operation is performed while spraying washer fluid toward the opposite side to a movement direction side of a wiper blade, after which a wiping operation in which washer fluid is not sprayed is performed.

The invention relates to a wiper arm (10; 10a-10d) for cleaning a vehicle window, with a carrier element (11), which is able to be connected at a first end region at least indirectly with a drive shaft and at another end region with a wiper blade (1), and with an additional element (30) connected with the carrier element (11), which additional element (30) extends in longitudinal direction of the wiper arm. It is provided according to the invention that the additional element (30) has at least one air guide section (166, 167), extending in longitudinal direction of the wiper arm (10; 10a-10d), which at least one air guide section (166, 167) projects beyond the underside (168) of the carrier element (11) on the side facing the vehicle window.

The invention relates to a cleaning arrangement (10; 10a) for a wiper arm (1) of a windscreen wiper system (100), wherein the cleaning arrangement (10; 10a) has at least one spray nozzle (21, 22) for a cleaning fluid, wherein the cleaning arrangement (10; 10a) is constructed to form en engagement connection (30) at the wiper arm (1), and wherein the engagement connection (30) comprises at the cleaning arrangement (10; 10a) at least one resiliently constructed engagement element (40; 40a) which is constructed to cooperate with an engagement mount (54; 54a) at the wiper arm (1). There is provision according to the invention for the cleaning arrangement (10; 10a) to have first guide means (35), which first guide means (35) are constructed to be able to rotate the cleaning arrangement (10; 10a) in a rotation axis (37) in order to establish the engagement connection (30).

A window wash nozzle for a vehicle includes a housing in which a nozzle element is pivotably mounted about a pivot axis. Actuation of an adjustment element pivots the nozzle element. A sliding piece mounted in an axially displaceable manner in the housing interacts with the adjustment element such that actuation of the adjustment element brings about an axial displacement of the sliding piece. A guiding cam is formed on the sliding piece and interacts with a transmission element such that the transmission element is adjusted in a direction transversely with respect to the direction of movement of the sliding piece during axial displacement of the sliding piece. The transmission element acts on the nozzle element excentrically with respect to the pivot axis of the nozzle element such that an adjustment of the transmission element brings about pivoting of the nozzle element about the pivot axis.

A system for a wiper arm comprises an attachment which may be, for example, a nozzle bar, wherein the attachment comprises a snap-in means and a channel, wherein the system further comprises a wiper rod, wherein the wiper rod comprises a snap-in means which is complementary to the snap-in means of the attachment. The system is configured such that the wiper rod can be inserted into the channel and then slid along the longitudinal axis of the channel in a direction (sliding direction) so far, until the snap-in means interlock, thereby preventing or limiting movement of the wiper rod within the channel and thus fixing the attachment to the wiper rod.

A wiper blade for a vehicle includes a wiper arm having one end installed at a windshield glass side and configured to rotate, and the other end at which an installation bracket is provided, a blade mounted on the installation bracket of the wiper arm and configured to clean a windshield glass, and a nozzle installed on an assembling part extending outward from the installation bracket of the wiper arm, the nozzle being positioned between the assembling part and the blade and configured to spray a cleaning liquid in a longitudinal direction in which the blade extends.

A vehicle wiper device includes a wiper arm, a wiper blade, a nozzle body, a hose, and a cleaning fluid supply section. A leading end side portion of the wiper arm is configured by an arm piece, and the wiper arm swings back and forth. The nozzle body is attached to the arm piece, is disposed on an outward movement side of the wiper blade, and jets cleaning fluid toward a windshield. The hose conveys cleaning fluid under pressure. The cleaning fluid supply section is at an opposite side of a rubber holder from the windshield, extends from the nozzle body so as to extend across the rubber holder from the outward movement side toward a return movement side of the wiper blade, is connected to the hose, and supplies cleaning fluid to the nozzle body.

A cleaning device for a vehicle has tracks above and below the vehicle's windshield. A brush, wiper blade and spray bar extend across the windshield at a starting side of the windshield. The spray bar provides washer fluid as the brush rotates against the windshield. The spray bar, rotating brush and wiper bar are moved along the tracks and across the windshield to an opposing, return side of the windshield where the wiper blade first contacts the windshield and the brush stops rotating and moves away from the windshield. The spray bar rotates next to the wiper blade to blow air against the windshield. The wiper blade scrapes water while air blows water off the windshield as they move back to the starting side of the windshield where they are stored in a frame along the side of the windshield when not in use.

Nozzles and systems for cleaning sensors of a vehicle are provided. An adjustable nozzle can include an inlet configured to receive a pressurized fluid, an adjustable oscillator coupled with the inlet, and an outlet coupled with the adjustable oscillator. The adjustable oscillator can be configured to receive the pressurized fluid from the inlet and generate an oscillating fluid, and can include a first oscillation wall comprising a first adjustable chamber modifier wall and a second oscillation wall comprising a second adjustable chamber modifier wall. The first adjustable chamber modifier wall and the second adjustable chamber modifier wall can define an adjustable mixing chamber configured to generate the oscillating fluid having one or more properties that are adjustable by the first adjustable chamber modifier wall or the second adjustable chamber modifier wall. The outlet can be configured to receive the oscillating fluid and eject the oscillating fluid from the adjustable nozzle.
