The invention relates to a windshield wiper device (100) for a vehicle, comprising a wiper blade (2) having an elongated upper part (10) and an elongated lower part (12), which are configured to be flexible, at least in part. Furthermore, the device comprises a plurality of connecting elements (18) for connecting the upper part (10) and the lower part (12), which are spaced apart from each other along a longitudinal extension (8) of the wiper blade (2), and which are configured to allow a movement of the upper part (10) and the lower part relative to one another with a motion component along a longitudinal extension (8) of the wiper blade (2). The windshield wiper device (100) further comprises a fastening device. The fastening device comprises a wiper-blade-side fastening part (20) and a fastening element (50). The wiper-blade-side fastening part (20) and the fastening element (50) are configured in such a manner that, by means of rotation of the wiper-blade-side fastening part relative to the fastening element, an engagement can be formed in order to fix a position of the wiper-blade-side fastening part relative to the fastening element.

A wiper blade for a vehicle includes a wiper arm having one end installed at a windshield glass side and configured to rotate, and the other end at which an installation bracket is provided, a blade mounted on the installation bracket of the wiper arm and configured to clean a windshield glass, and a nozzle installed on an assembling part extending outward from the installation bracket of the wiper arm, the nozzle being positioned between the assembling part and the blade and configured to spray a cleaning liquid in a longitudinal direction in which the blade extends.

A vehicle wiper device includes a wiper arm, a wiper blade, a nozzle body, a hose, and a cleaning fluid supply section. A leading end side portion of the wiper arm is configured by an arm piece, and the wiper arm swings back and forth. The nozzle body is attached to the arm piece, is disposed on an outward movement side of the wiper blade, and jets cleaning fluid toward a windshield. The hose conveys cleaning fluid under pressure. The cleaning fluid supply section is at an opposite side of a rubber holder from the windshield, extends from the nozzle body so as to extend across the rubber holder from the outward movement side toward a return movement side of the wiper blade, is connected to the hose, and supplies cleaning fluid to the nozzle body.

The wiper device includes a carrier element and a wiper blade with at least one longitudinal groove, in which groove the carrier element is disposed. The wiper device also includes a connecting device for pivotally connecting the wiper blade with an oscillating arm. The connecting device has spaced-apart sidewalls, each with a protrusion that extends sidewardly and outwardly. The connecting device and oscillating arm are interconnected by the protrusions pivotally and snappingly engaging into correspondingly shaped recesses of the oscillating arm. The oscillating arm has a guiding tongue engaging into a guiding groove of the connecting device. The connecting device has an asymmetric form with respect to its middle transverse plane, seen in vertical direction, in order to ensure that the wiper blade can only be mounted on the oscillating arm in a predetermined orientation of the wiper blade relative to the oscillating arm.

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 arm device with an integrally formed wiper arm element (10) which is provided with a fastening part (12) for articulated connection and which has at least one wiper arm element portion (14) with a longitudinal extent of at least 10% of the total longitudinal extent of the wiper arm element (10). According to the invention, it is proposed that the wiper arm element portion (14) has a cross-section that differs from an at least substantially U-shaped cross-section.

A windscreen wiper device, particularly for automobiles, comprises an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade is of the flat blade type and includes at least one groove, in which groove an elastic, elongated carrier element is disposed, wherein the windscreen wiper device further comprises a mounting head for transferring a reciprocal movement to the wiper blade, with the special feature that the windscreen wiper device further comprises a longitudinal strip-shaped arm, wherein the arm near a first end thereof is directly connected to the mounting head and near a second end thereof is directly connected to a connecting device of the wiper blade, and wherein the arm made of a resilient material is biased in order to exert a pressure onto the wiper blade towards the windscreen to be wiped.

A wiper (14) for wiping a window pane (12) of a motor vehicle is provided, having a drive shaft (16) that can be driven by a motor, and a wiper lever (18) connected to the drive shaft (16) for moving a wiper blade. The wiper lever (18) is flexibly bendable. A maximum bending angle (20) of the wiper lever (18) around a bending axis extending perpendicular to the drive shaft (16) is limited by a limit stop (32) to bending of the wiper lever (18) in the range of elastic deformation. The limit stop (32) makes stop contact at the maximum bending angle (20) and can keep the deformation of the wiper lever (18) reliably in the range of elastic deformation, thus reducing the risk of damage to wipers (14).

A multiple windshield wiper assembly is disclosed. The multiple windshield wiper assembly may comprise a first wiper assembly having a squeegee blade; a second wiper assembly having a scraper blade, the second wiper assembly being coupled to the first wiper assembly by a windshield wiper assembly connector; wherein the scraper blade comprises an attachment surface for engaging a wiper assembly, a scraper surface for engaging a windshield, a channel for conducting wiper fluid, a plurality of apertures for disbursement of the wiper fluid onto a windshield, and a water connection fitting for connection of the scraper blade to a vehicle water supply hose. A number of embodiments of a windshield wiper assembly connector for use in connecting one or more windshield wiper assemblies to pin-type and hookslot-type wiper arms are also disclosed.

The present invention relates to a method (100) for manufacturing a cleaning arm (10) of a cleaning system (200), comprising the steps of: cold forming (S1) of a blank with at least one hole (11) for forming a bottom element (12), a side element (14) formed to be essentially orthogonal to the bottom element (12), a bushing (16) for attaching the cleaning arm (10) to a cleaning motor (202) of the cleaning system (200), a web (18), wherein the hole (11) is disposed on the web (18), wherein the hole (11) is positioned such that a stud (20) can be positioned in the hole (11) for attaching a spring (26).
