A windscreen wiper arm, particularly for automobiles, that is able to oscillate upwardly and downwardly between a downward position and an upward position. One end of the windscreen wiper arm is adapted to be pivotally connected to a mounting head mounted on a drive shaft. Another end of the windscreen wiper arm is rigidly connected to an adapter adapted to be connected to an elongated wiper blade to be placed in abutment with a windscreen to be wiped. The adapter, at the location of its connection to the wiper blade, has a U-shaped cross-section with a base and two spaced-apart legs. The U-shaped cross-section is preferably mounted offset in a plane of the base relative to a longitudinal axis of the windscreen wiper arm. The windscreen wiper arm is provided with a nozzle for spraying a washing liquid onto the windscreen to be wiped. The nozzle is detachably connected to the adapter through a key hole connection.

A windscreen wiper device of the flat blade type comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes at least one longitudinal slit, in which slit at least one longitudinal strip of the carrier element is disposed, which windscreen wiper device comprises a connecting device for a rod-like extension of an oscillating arm, wherein said rod-like extension can be pivotally connected to said connecting device about a pivot axis near a free end thereof, with the special feature that said connecting device comprises a channel arranged to receive said free end of said rod-like extension, wherein said windscreen wiper device comprises a nozzle for spraying a washing liquid onto said windscreen to be wiped, wherein said nozzle being mounted onto said rod-like extension, and wherein said rod-like extension at a side facing towards said connecting device extends in longitudinal direction beyond said nozzle.

An improved nozzle assembly includes a housing having an inlet for directing media (e.g. cleaning fluid) into the housing, and a nozzle core rotatably coupled to the housing. The nozzle core includes a sprayer shaft and a vane coupled thereto. The sprayer shaft defines a peripheral outlet, and is adapted for passage of media from the housing through the outlet. The vane is adapted to receive media from the inlet to rotationally bias the nozzle core in a first direction and radially orient the outlet to an activated position. The nozzle core is rotationally biased in a second direction opposite the first to radially orient the outlet to a home position different than the activated position. A system including the nozzle assembly, and methods of using each of the same, are also disclosed.

According to one aspect, a vehicle includes a chassis, a propulsion system carried on the chassis, a control system carried on the chassis, and a components arrangement carried on the chassis. The propulsion system configured to propel the vehicle, and the control system is configured to enable the vehicle to operate autonomously. The components arrangement includes at least a frame, a panel having a surface, a wiper arrangement having at least one wiper, and a fluid distribution arrangement. The frame is configured to interface with the chassis and to support the panel, the wiper arrangement, and the fluid distribution arrangement. The fluid distribution arrangement is configured to dispense a fluid onto the surface and the wiper is configured to sweep over the surface.

A windscreen wiper system for a motor vehicle includes at least one wiper blade which has a slider secured to a wiper blade element. An adapter is connected to the slider in an articulated manner. The adapter is connected to a component of a wiper arm of the windscreen wiper system via a recess. The adapter is connected to a wiper rod of the wiper arm via the recess. A further functional element is arranged on the wiper rod of the wiper arm separately from the adapter.

Provided is a wiper arm including: an arm head in which a base end is attached to a swing shaft; an arm shank in which a base end is attached to a tip of the arm head; an arm piece in which a base end is attached to a tip of the arm shank; a washer tube; a washer nozzle attached to a tip of the washer tube; and a cover member covering at least the surrounding of a part of the arm piece and the washer tube in a longitudinal direction. The cover member includes: a first cover body, having a top wall portion, and side wall portions protruding from both sides of the top wall portion in a short-side direction; and a second cover body, attached to the side wall portions and disposed to face the top wall portion.

A windscreen wiper arm, particularly for automobiles, that is able to oscillate upwardly and downwardly between a downward position and an upward position. One end of the windscreen wiper arm is adapted to be pivotally connected to a mounting head mounted on a drive shaft. Another end of the windscreen wiper arm is rigidly connected to an adapter adapted to be connected to an elongated wiper blade to be placed in abutment with a windscreen to be wiped. A joint part is adapted to be interposed between the adapter and the elongated wiper blade. The adapter, at the location of its connection to the wiper blade, has a U-shaped cross-section with a base and two spaced-apart legs. The windscreen wiper arm is provided with a nozzle for spraying a washing liquid onto the windscreen to be wiped. The nozzle is detachably connected to the adapter. At least one protrusion of the nozzle engages into a corresponding hole in one of the legs of the U-shaped cross-section of the adapter. The protrusion extends inwardly in a direction towards the adapter. The protrusion has a shank passing through the hole, and an enlarged head abutting an inner wall of the leg provided with the hole. The joint part is provided with a slit in which the enlarged head rests for blocking any movement of the protrusion in a direction towards the windscreen to be wiped and in a direction away from the windscreen to be wiped.

A device is described for protecting a sensor window. The device includes a two-piece nozzle system and is configured for generating a first and a second fluid flow, a first piece of the two-piece nozzle system being fixedly situated with respect to the sensor window, and a second piece of the two-piece nozzle system being configured for assuming different positions with respect to the first piece of the two-piece nozzle system, and the two-piece nozzle system being aligned with respect to the sensor window to direct a predominant portion of the first fluid flow in parallel to the sensor window and to direct a predominant portion of the second fluid flow in the direction onto the sensor window.
