The invention is directed to a wiper arm arrangement comprising a wiper bar (10), a coupling unit (12) and a fastening unit (14) for securing the coupling unit (12) to the wiper bar (10). According to the invention, the coupling unit (12) has a crimped profile (16, 54) which, in a mounted state, is to be connected to a washer fluid hose (18).

The invention relates to a wiper device (100) for the cleaning of vehicle windows (1), with a wiper blade (10) fastened exchangeably on a wiper arm (2), which wiper blade is connected with the wiper arm (2) via a wiper blade adapter (11), wherein in the fastening region to the wiper blade (10) the wiper arm (2) has a substantially U-shaped cross section, which embraces the wiper blade adapter (11), wherein on the wiper arm (2) in the connecting region a securing element (27) for the wiper blade adapter (11) is provided which is movably arranged at least in the longitudinal direction of the wiper arm (2) and which partially overlaps the wiper arm (2) in the connecting region and has a substantially U-shaped cross section with holding sections (46, 47) projecting inwards in the direction towards the wiper blade adapter (11). It is provided according to the invention that, in addition to its longitudinal displaceability, the securing element (27) is arranged pivotably on the wiper arm (2).

A vehicle windshield wiper device comprising an articulated structure and a blade, the articulated structure comprising an arm transmitting mechanical forces to the blade, wherein the arm is mounted on an axle to provide an arm rotational movement corresponding to a wiping movement, wherein the arm is pivotably attached to the axle. The vehicle windshield wiper device also comprises an arm holder restraining the arm from pivoting when blade is in a parking position.

A wiper arm properly connects a retainer and an arm piece, even if a radius of curvature in a bent portion of a holding part of the retainer is set large, in the wiper arm including the arm piece connected to the retainer by accommodating and holding a held part of the arm piece within the holding part of the retainer. An arm piece includes a held part including chamfered portions disposed opposite to bent portions of a holding part of a retainer. A held part has a flat upper surface between the chamfered portions and is held within an accommodating portion of the holding part so that the upper surface abuts on a lower surface of a flat top wall of the holding part. The chamfered portions are formed so that a width of the upper surface is not larger than a width of the lower surface.

A window wiper device (1, 20, 40, 100) having a pantographic arm (22) at the end of which a main wiper blade is attached. A secondary wiper blade (101), placed beneath the main wiper blade (32), is mounted on the pantographic arm (22) by means of a pantographic device that is intended to offset the secondary wiper blade (101) from the main wiper blade (32), such that the two wiper blades (32, 101) can perform their wiper functions continuously on the window (10).

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 groove, in which groove at least one longitudinal strip of the carrier element is disposed, which windscreen wiper device comprises a connecting device (1) for a rod-like extension (2) of an oscillating arm, wherein said rod-like extension (2) can be pivotally connected to said connecting device (1) about a pivot axis near a free end thereof, wherein said connecting device (1) comprises a channel (15) arranged to receive said rod-like extension (2), wherein the connecting device (1) comprises a first and a second retention mechanism for retaining said rod-like extension (2) on said connecting device (1), wherein said first and second retaining mechanisms are arranged to engage in a first, respectively second recess provided on at least one longitudinal exterior side (18a, 18b) of said rod-like extension (2), wherein said channel (15) at least at the entrance and at the opposite end of said entrance has the same width for receiving a rod-like extension (2) having a substantially constant width along the distal end thereof.

Provided is a rear wiper assembly having a rear wiper arm, a cover, a joint, and a motion-stopping mechanism. A connector and a cover are hingedly connected to the rear end of the rear wiper arm. When the cover is in a closed state, it covers the connector; the motion-stopping mechanism has a first interference element and a second interference element, at least one of the interference elements being a flexible element; the first interference element is arranged on the rear wiper arm, and the second interference element is arranged on the cover, when the cover is in an open state and when the angle between the upper surface of the cover and the upper surface of the rear wiper arm is within a predetermined range, the interference elements interfere with each other, preventing the cover from turning over in the direction of the connector.

A windshield wiper system has a drive arm with a drive shaft connector, a curved cantilever beam, and a wiper blade assembly. The drive arm is configured to connect to a drive shaft at the drive shaft connector. The curved cantilever beam is connected to the drive arm with a first drive arm fastener and a moveable drive arm fastener. The first drive arm fastener is positioned on the drive arm between the drive shaft connector and the moveable drive arm fastener. The wiper blade assembly is connected to the curved cantilever beam with a wiper blade fastener. The curved cantilever beam has an effective length extending from the moveable drive arm fastener to the wiper blade assembly fastener.
