The present invention relates to a windscreen wiping device (100) for a vehicle, comprising a wiper blade (2) with an elongate upper part (10) and an elongate lower part (12), which are configured to be at least partially bendable. Furthermore, a plurality of connecting elements (18) for connecting the upper part (10) and the lower part (12) are provided, said connecting elements being spaced apart from one another along a longitudinal extent (8) of the wiper blade (2) and being designed to permit a movement of the upper part (10) and of the lower part relative to each other with a movement component along a longitudinal extent (8) of the wiper blade (2). Furthermore, the windscreen wiping device (100) 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.

The invention proposes a wiper device for wiping a window of a motor vehicle, comprising a head of a wiper arm, a housing of a drive motor for driving the head of the wiper arm, a circulation channel for circulating cleaning liquid to the wiper, extending through the drive motor housing and the head of the wiper arm. The device enables a simpler definition of the liquid circulation channel.

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. Protrusion/groove features are provided on the part and the side walls for limiting a pivot angle of the arm member. The protrusion/groove means comprise at least one groove and at least one protrusion cooperating with the groove, the protrusion is movable in the groove between a first position corresponding with a wiping position of the arm member and a second position corresponding with a mounting position of the arm member. The part is provided with opposite abutting surfaces for abutting against the side walls. The protrusion extends laterally inwardly from one of the side walls into the groove being provided on one of the abutting surfaces abutting against that respective side wall. The groove has a width larger than a width of the protrusion.

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.

A wiper apparatus includes a wiper axis interface configured for mounting a wiper assembly to a wiper drive. A lower wiper arm extends from the wiper axis interface to a wiper mount that is configured to connect the lower arm to an upper arm. A first end of the lower wiper arm proximate the wiper axis interface has a first airfoil profile and wall thickness. A second end of the lower wiper arm proximate the wiper mount has a second airfoil profile and wall thickness. An intermediate portion of the lower wiper arm extending between the first and second ends has a transitioning airfoil profile and thickness that transitions from the first airfoil profile and wall thickness to the second airfoil profile and wall thickness.

A wiper device includes: lock grooves provided at an arm head and recessed toward both sides in a wiping direction of a wiper blade; and lock claws provided at an arm shank and protruding toward both sides in the wiping direction of the wiper blade. By concave-convex mating of the lock grooves and the lock claws with each other, the arm shank is restricted from rotating by degrees (about 22 degrees) or more with respect to the arm head, and a state in which the arm shank stands up by degrees (about 20 degrees), which is smaller than degrees, with respect to the arm head is maintained.

The present disclosure provides a rear wiper and a vehicle. The rear wiper includes an arm support, having a first end portion and a second end portion, wherein the arm support is driven to pivot at the first end portion thereof, such that the rear wiper wipes a rear windshield, and a wiper arm, having a first connecting end, wherein the first connecting end is connected to the second end portion of the arm support, and the wiper arm is rotatable relative to the arm support between a first position close to the rear windshield and a second position away from the rear windshield. The wiper arm includes a stop part, which is located at the first connecting end and is capable of abutting against the arm support, and when the stop part abuts against the arm support, the wiper arm is in the second position.
