An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a distal end of the wiper arm, and a drive shaft coupled to a proximal end of the wiper arm. The wiper blade is configured to clean water, dirt, and other debris from the windshield of the aircraft. The drive shaft is configured to rotate and cause the wiper arm with the coupled wiper blade to sweep across the windshield. The wiper arm includes both composite and metal components to reduce the weight of the windshield wiper system while also providing lightning strike protection.

A windscreen wiper device of the flat blade type having an elastic, elongated carrier element and an elongated wiper blade of a flexible material, adapted to be placed in abutment with a windscreen to be wiped. The wiper blade includes at least one longitudinal slit, in which at least one longitudinal strip of the carrier element is disposed. The windscreen wiper device comprises an oscillating arm having a rod-like extension, a connecting device and a nozzle for spraying a washing liquid onto the windscreen to be wiped. The connecting device includes a channel adapted to receive a free end of the rod-like extension. The nozzle is adapted to be mounted onto the rod-like extension. The nozzle and the connecting device are provided with mutually cooperating protrusion/groove means for locking the nozzle onto the connecting device upon insertion of the free end of the rod-like extension inside the channel of the connecting device.

A wiper device (10a-10c) is proposed comprising at least one wind deflector unit (12a-12c) and comprising at least one channel unit (18a-18c) integrated into the at least one wind deflector unit (12a-12c), and comprising at least one wiper blade adapter (20a-20c) which includes at least one adapter attachment (24a-24c) and at least one adapter base body (22a-22c) and is configured to be coupled to at least one wiper arm (110a-110c). It is proposed that the wiper device (10a-10c) comprise a fluid supply unit (38a-38c) which is configured to supply wiper fluid to the channel unit (18a-18c) and comprises at least one coupling end piece (40a-40c) for latching connection to the at least one adapter attachment (24a-24c).

A windshield wiper arm is provided on an outside of an aircraft and positioned to directly engage an air flow while the aircraft is traveling. The wiper arm includes an arm portion coupled to the aircraft and having an arm exterior surface, the arm portion extending along an arm axis and defining an arm length. A bead extends outwardly from the arm exterior surface and defines a bead exterior surface, the bead being sized sufficiently to engage a boundary layer of the air flow. A wiper blade is coupled to the arm portion. The bead prevents separation of the boundary layer from the arm exterior surface, thereby to attenuate shedding of vortices and associated vibrations and noise.

System for wiping a glazed surface of a vehicle, comprising a wiper blade (110) comprising a connector (124), a drive arm (112) for driving the wiper blade (110), the drive arm (1125 comprising at least one hinge means allowing the connector (124) to rotate relative to the drive am (112), a connecting piece (23) in contact with the connector (124) and positioned on the hinge means, said connecting piece (23) comprising means for spraying liquid towards the glazed surface,
characterized in that said connecting piece (23) is configured to follow a movement of the wiper blade (110) over the glazed surface.

The present invention relates to a windscreen wiper (1) for a motor vehicle window (3), comprising: a longitudinally extending wiper blade (5), an aerodynamic deflector (9) extending longitudinally above said wiper blade (5), at least one longitudinally extending fluid circulation duct (31, 32) having at least one spraying orifice (35), characterized in that the wiper comprises at least one lower lateral skirt (43, 44) extending longitudinally on a lateral side of the wiper blade (5) and of the spraying orifice (35), the spraying orifice (35) being located between the wiper blade (5) and the lower lateral skirt (43, 44).

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.

An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a distal end of the wiper arm, and a drive shaft coupled to a proximal end of the wiper arm. The wiper blade is configured to clean water, dirt, and other debris from the windshield of the aircraft. The drive shaft is configured to rotate and cause the wiper arm with the coupled wiper blade to sweep across the windshield. The wiper arm includes both composite and metal components to reduce the weight of the windshield wiper system while also providing lightning strike protection.

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.
