An on-board sensor cleaning device is provided for an on-board sensor including a sensing surface. The on-board sensor cleaning device includes an ejection port that ejects fluid toward the sensing surface when the ejection port is disposed outside a sensing range of the on-board sensor. The on-board sensor cleaning device further includes a movable nozzle configured to move the ejection port so that a position of an ejection axis of the ejection port changes.

The invention relates to a tube holder for a wiper arm, comprising a bracket, a positively locking closure and a tube receptacle as well as a wiper receptacle, wherein the bracket can be folded onto the tube receptacle so that the wiper receptacle can be closed by the bracket, the bracket being fixed onto the wiper receptacle by means of the closure.

An on-board sensor cleaning device includes a nozzle including one or more ejection ports that eject a fluid onto a sensing surface of an on-board sensor; wherein an ejection duration or an ejection frequency of the fluid, which is ejected onto the sensing surface, differs in accordance with a position on the sensing surface.

A windscreen wiper arm, particularly for automobiles, is provided. The windscreen wiper arm is, at one end thereof, arranged to be pivotally connected to a mounting head mounted on a drive shaft and, at another end thereof, arranged to be pivotally connected to an elongated wiper blade to be placed in abutment with a windscreen to be wiped. The windscreen wiper arm can oscillate to-and-from between a first reversal position and a second reversal position. The windscreen wiper arm is provided with a tab extending downwardly from a top wall of the windscreen wiper arm. The tab is connected to a nozzle for spraying a washing liquid onto the windscreen to be wiped.

A wiper assembly (100) is provided, comprising a wiper arm (110), a wiper blade (120), and a coupling device (130) configured to enable connection of the wiper blade (120) to the wiper arm (110), wherein the coupling device (130) comprises a first part (140) being connected to one of said wiper arm (110) or said wiper blade (120), and a second part (150) being connected to the other one of said wiper arm (110) or said wiper blade (120). The first part (140) comprises an engaging section (142) being configured to provide an axial fixation of the first part (140) relative the second part (150), and at least one recess (144) configured to provide a rotational fixation of the first part (140) relative the second part (150), and wherein the second part (150) comprises a receiving section (152) configured to receive the engaging section (142) of the first part (140), a locking device (160) arranged radially outwards of said first part (140) and comprising at least one radial protrusion (162) configured to fit with said recess (144) of the first part (140), and a wall (170) surrounding said locking device (160), wherein said wall (170) comprises a constricted section (172) whereby an inner wall (174) of said constricted section (172) is configured to press the radial protrusion (162) radially inwards when the constricted section (172) is axially aligned with the radial protrusion (162).

In the method for controlling at least one washing device of at least one sensor situated on an outer contour of a vehicle, a completed vehicle wash of the outer contour of the vehicle is initially recognized. In this case, sensors, for example, are distance sensors, which detect the surroundings of a vehicle and are situated for this purpose on the outer body of the vehicle. As a result of a completed vehicle wash, the externally mounted sensors are cleaned as well and, therefore, after a vehicle wash, it may be assumed that these sensors are now free of dirt. First control signals for actuating the at least one washing device of the at least one sensor are generated depending on a recognized vehicle wash, which was carried out, for example, in a car wash.

A cleaning device for a surface, such as a windshield of a vehicle, has a housing that holds a spray bar, rotatable brush and a wiper blade. An engagement mechanism moves spray bar, the brush, and the wiper blade out from a disengaged position within the housing to an engaged position outside the housing so that they can be used to clean, brush, and dry the surface. After the spray bar, brush, and wiper blade are used to, respectively, clean, brush, and dry the surface, the engagement mechanism then moves the spray bar, the brush, and the wiper blade to a disengaged position within the housing.

The on-vehicle optical sensor cleaning system includes a washer pump that feeds a cleaning liquid, an air pump, a nozzle member, and a controller. The air pump includes a discharge valve and discharges air through the discharge valve. The discharge valve opens when air is compressed in the air pump. The nozzle member includes an ejection port that ejects a gas-liquid mixture toward a sensing surface of an on-vehicle optical sensor to remove foreign matter from the sensing surface. The cleaning liquid from the washer pump and the air from the air pump are mixed in the gas-liquid mixture. The controller controls the washer pump and the air pump. The controller is configured so that the gas-liquid mixture is ejected by storing the cleaning liquid in the nozzle member to cover the ejection port and then feeding the air to the nozzle member.

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.
