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.

The invention relates to a window-wiping device for a vehicle having a fastening element fastened to a drive shaft, in particular a motor vehicle. The window-wiping device comprises a wiper blade having an elongate upper part, which is at least partially flexible, an elongate lower part, which is at least partially flexible, a plurality of connecting elements for connecting the upper part and the lower part, wherein the connecting elements are spaced apart from each other along a longitudinal extent of the wiper blade, and wherein the connecting elements are designed to enable a motion of the upper part and of the lower part in relation to each other with a motion component along a longitudinal extent of the wiper blade, and a wiper-blade-side fastening part, wherein the wiper-blade-side fastening part can be detachably connected by means of a linear motion on the fastening element, and the wiper-blade-side fastening part can be connected to the fastening element in such a way that a rotational position about an axis perpendicular to the longitudinal extent of the wiper blade and perpendicular to the linear motion is defined by a support and a further contact point.

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.

A wiper apparatus which removes foreign matters from a windshield by rotating by a pivot of a vehicle may include an arm piece connected to one end of an arm retainer to connect a wiper blade, and a coupling portion having a step portion formed to extend along a longitudinal direction so that an upper surface of the arm piece and an upper surface of the arm retainer form a same surface when coupled to correspond to a coupling hole formed in the arm retainer.

Provided is a bearing device capable of suppressing corrosion for a long time. The bearing device is for use in a wiper arm to pivotably attach a retainer to an arm head. The bearing device includes an outer bushing press-fitted into a hinge portion of the arm head, an inner bushing rotatably inserted into a bore in the outer bushing, and a rivet inserted into a bore in the inner bushing to secure the retainer and the inner bushing together integrally. Thus, a hinge portion of the retainer, the inner bushing, and the rivet are pivotable relative to the hinge portion of the arm head and the outer bushing. The outer bushing has an inside bushing part and an outside bushing part provided around the outer periphery of the inside bushing part and joined to the inside bushing part. The joint surface of the inside bushing part and the joint surface of the outside bushing part are joined to each other by interatomic bonding. The outside bushing part is formed of the same material as that of the arm head.

A windscreen wiper arm, particularly for automobiles, includes a mounting head mountable on a drive shaft and an arm member pivotally connected to the mounting head by means of a pivot pin. The arm member has a substantially U-shaped cross-section near the pivot pin comprising two side walls. A part of the mounting head extends between the side walls and beyond the pivot pin. The part is provided with opposite surfaces each facing towards a respective side wall of the arm member. Each surface of the part of the mounting head is positioned spaced-apart from its respective side wall of the arm member, so as to allow paint to enter a space defined between each surface of the part of the mounting head and its respective side wall of the arm member.

The windscreen wiper device includes a wiper blade that extends lengthwise in a longitudinal direction. A pre-curved carrier element with opposing lateral edges biases the wiper blade into a curved shape. At least one projection of a connector base is received in at least one notch of the carrier element for restricting relative longitudinal movement between the connector base and the carrier element. The connector base also at least one long locking arm and at least one short locking arm which engage around the lateral edges of the carrier element to lockingly connect the connector base with the carrier element. The at least one short locking arm has a lateral width which is less than the at least one long locking arm. The at least one short locking arm has a ramped lower surface for allowing the at least one short locking arm to snappingly engage the carrier element.

An arm of a wiping system is disclosed. The arm includes a part extending longitudinally. The part is configured to be connected by a first end to an arm drive device and by a second end to an attachment device for attaching the arm to a wiper blade. The part includes a main beam extending in the longitudinal direction. The part is in a single piece and the part also includes at least one additional beam extending in the longitudinal direction.
