A windscreen wiper arm, particularly for automobiles, that is able to oscillate upwardly and downwardly between a downward position and an upward position. The windscreen wiper arm comprises a wiper arm member having a substantially U-shaped cross-section, as well as a wiper rod. The wiper arm member at one end is adapted to be pivotally connected to a mounting head mounted on a drive shaft. The wiper arm member at another end is rigidly connected to the wiper rod. The wiper rod at one end extends inside the U-shaped cross-section of the wiper arm member, and the wiper rod at another end 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 mounted offset in a plane of the base relative to a longitudinal axis of the wiper rod. 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 a lateral side of the windscreen wiper arm facing towards the upward position.

A contaminant removal apparatus for windshields includes: driving belts located at both side surfaces of a windshield; a drive unit configured to apply driving force to the driving belts; a wiper assembly located on the windshield; rotary rollers configured to be shifted along the driving belts; idle gears located at ends of the driving belts to change a rotating direction of the rotary rollers; frame connection shafts coupled to both ends of the wiper assembly and located within the rotary rollers so as to contact the idle gears to change the rotating direction of the rotary rollers; and a controller configured to change a rotating direction of the rotary rollers when the idle gears and the frame connection shafts contact.

The invention relates to a wiper device, in particular a windscreen wiper device, having a wiper arm adapter (10) and having a wiper blade adapter (12), the wiper arm adapter (10) being provided for coupling to the wiper blade adapter (12) in the main extension direction of the wiper blade adapter (12), and further having a wiper arm channel element (14) of a spray unit (34). According to the invention, the wiper arm channel element (14) is provided for coupling to a wiper blade channel element (16) of the wiper blade adapter (12) in a main extension direction of the wiper blade adapter (12).

A wiper assembly includes a bent arm providing a channel. The bent arm is configured to connect to a shaft of an actuator. The wiper assembly additionally includes a wiper blade slidably received within the channel. A method includes securing a bent arm to a shaft of an actuator, and biasing a wiper blade against a window during the securing.

A wiper system including wiper blades with different lengths may include: an arm to be rotated, and a blade to be rotated with the arm. In particular, the arm includes a retainer to press the blade, and the blade includes: a primary coupled to a front end of the retainer; and a plurality of yokes coupled to the primary and to receive a transferred pressing force and to transfer the pressing force to a bertebra coupled to a lower side thereof.

An automobile vehicle wiper arm system includes a wiper arm base rotatably connected to a fixed structural member. A wiper arm extension is slidably disposed to the wiper arm base during wiper arm base travel about an arc of travel. A motion link is rotatably connected to the wiper arm extension and is rotatably connected to the fixed structural member. The motion link induces the wiper arm extension to outwardly displace and inwardly displace opposite to the outward displacement during wiper arm base rotation about the arc of travel. A wiper blade is connected to the wiper arm extension and traverses an oval-shaped travel arc along a vehicle windshield by the slidable displacement of the wiper arm extension during wiper arm base rotation. A linkage group connects the wiper arm extension to a wiper motor with rotation of the wiper arm base induced by operation of the wiper motor.

The invention relates to a wiper arm (10) for a windscreen wiper system of a motor vehicle, with a receiving region (11) for a wiper blade adapter (55), wherein in the receiving region (11) an adapter element (30; 30a) is arranged, serving for the supplying of washing fluid, wherein the adapter element (30; 30a) is able to be connected on the one hand with a supply line (32) for the washing fluid and on the other hand has at least one outlet (34) for the washing fluid, which is able to be connected with the wiper blade adapter (55), wherein the at least one outlet (34) is aligned with a first mounting or respectively dismantling direction (17) of the wiper blade adapter (55).

Casing (20) for a windscreen wiper drive rod, in particular of a motor vehicle, said casing being configured to cover at least a portion of said drive rod and comprising means for fixing to said drive rod and/or to at least one element (42) linked to said drive rod, characterised in that it further comprises support and guiding means (70) which are configured to cooperate with at least one electric cable (63) and/or at least one fluid line (64) of said windscreen wiper.

The invention relates to a cleaning arrangement (40; 40a-40d) for cleaning a vehicle window, with a wiper arm (10; 10a-10d) and with at least one hose (31, 32), fastened to the wiper arm (10; 10a-10d), for a cleaning fluid. It is provided according to the invention that the hose (31, 32) is connected by a form-fitting fastening, secure with regard to rotation angle, at least indirectly to the wiper arm (10; 10a-10d).

A wiper arm and assembly are disclosed. The wiper arm has a wiper arm holder, connected at one end to an output portion of a driving mechanism for the wiper arm that drives the wiper arm to swing back and forth in an outward-swinging direction, an extension arm pivotally connected to the other end of the wiper arm holder, a wiper arm end member located on the side of the wiper arm opposite to the wiper arm holder and configured to hold a wiper blade, and a washer assembly having at least a first nozzle, and a first conduit in fluid communication with the first nozzle. The first nozzle includes a nozzle unit, a first connector for the first conduit, and a bridge channel located between them, above the blade. The bridge channel is partially aligned with a segment of the wiper arm end member that is located above the blade.
