According to the invention, the first coupling element (22) is formed at least in part by the hose guide (14).

The invention relates to a wiper arm spraying device (10a; 10b) for coupling to a wiper arm (12a; 12b), comprising at least one valve unit (14a; 14b) which is designed to supply a nozzle unit (16a; 16b) with wiper fluid. According to the invention, the valve unit (14a; 14b) is designed for integration into a wiper arm tube unit (18a; 18b).

The present disclosure relates to a wiper connector, a wiper blade assembly, and a wiper device, and a wiper connector for mutually connecting a wiper blade and a wiper arm includes an insertion portion inserted into the wiper arm and disposed at one side of a washing liquid spray nozzle provided on the wiper arm, and a fixing portion integrally provided with the insertion portion and fixed to the wiper blade, wherein the insertion portion includes a first fastener caught by a hole provided in an upper surface of the wiper arm, and a second fastener caught by a rib provided inside the wiper arm.

The invention concerns a module (10) for cleaning a device (3) for protection of an optical element having a surface of revolution around an axis of revolution, the cleaning module (10) including a wiper blade (11) configured to extend in a first general direction (D1) and including a wiper rubber (111) configured to extend in a second general direction (D2). According to the invention: the wiper rubber (111) is configured to wipe the surface of revolution during relative movement of rotation between the wiper blade (11) and the protection device (3), and the cleaning module (10) further includes a cleaning liquid feed pipe (13) fixed to the wiper blade (11) and including at least one opening (131) for spraying cleaning liquid disposed in such a manner as to define a spraying direction forming an angle less than 15° with the second direction (D2). The invention also concerns a corresponding driving assistance system.

A vehicle cleaner nozzle injects a cleaning medium on an object to be cleaned which is mounted on a vehicle. The vehicle cleaner nozzle includes a housing, a nozzle chip accommodated in an interior of the housing, and a holder configured to support the housing in a state where the housing accommodates the nozzle chip. A feedback flow path for swinging and injecting the cleaning medium is formed by accommodating the nozzle chip in the housing.

Provided is a windshield wiper arm. This windshield wiper arm includes: an arm head (10); a shank; an arm piece connected to the windshield wiper blade; a washer nozzle which sprays a washer liquid onto the wiping surface; and a hose. The hose is divided into a first hose disposed along the arm head and a second hose disposed within the vehicle body. The first hose and the second hose are connected in a manner that washer liquid can flow from one hose to the other via a joint member (70). The arm head (10) has an opening part (10A) which opens on a fastening part 11 side, and the joint member (70) is mounted to the arm head (10) in a manner that the part of the joint member (70) that connects with the second hose penetrates the opening part (10A).

An attachment for a wiper arm of a windscreen wiper of a vehicle, having a rod arm, comprises a fluid channel for conducting a fluid and a first dimensionally stable element, wherein a first fluid channel section is formed in the first dimensionally stable element. The attachment also comprises a second dimensionally stable element, wherein a second fluid channel section is formed in the second dimensionally stable element. A wiper arm including the attachment is also disclosed.

A windshield wiper arm includes: an arm piece to which a wiper blade wiping a wiping surface is connected; a hose supplied with washer fluid; and a washer nozzle connected to the hose and mounted on the arm piece on the base end side with respect to a portion connected to the wiper blade. The washer nozzle includes: a first flowpath extending in a longitudinal direction; a second flowpath connected to the first flowpath and extending in a wiping direction which intersects the longitudinal direction, and in which the wiper blade can move when wiping the wiping surface; a third flowpath connected to the second flowpath and extending in a vertical direction which is along a normal line of the wiping surface while intersecting the longitudinal direction and the wiping direction; and a fitting groove into which the arm piece is fitted and which extends along the longitudinal direction.

The invention proposes an arm assembly comprising an arm adapter (20) comprising a distal section (20D) for supporting a wiper blade, a proximal section (20P) for housing a terminal section of a fluid delivery tube (26) and a terminal portion (21) for connecting the arm adapter (20) to a wiper arm rod (23), wherein the arm adapter (20) is provided with at least one retention device for fixedly retaining the terminal section of the fluid delivery tube with respect to said arm adapter, for example in the form of a retaining clip (32) attached to the proximal section (20P).

A device which is designed to detect surroundings and which includes a housing and a sensor situated within the housing. The housing includes a transmitter/receiver window, through which the corresponding sensor signals may be emitted into the surroundings by the sensor, and/or sensor signals from the surroundings may be received. The device includes a cover, the cover being designed to be transparent to the sensor signals, and the cover being designed to cover the transmitter/receiver window against exterior surroundings of the device. The device includes a cleaning unit, which is situated at an outside of the housing and is movable relative to the housing using a drive unit. The cleaning unit is designed to remove contaminants from the cover. The cleaning unit includes at least one first nozzle to spray a cleaning liquid onto the cover, and at least one second nozzle to blow a gas onto the cover.
