The present invention relates to a window-wiping device (100) for a vehicle, comprising a wiper blade (2) having an elongate upper part (10) and an elongate lower part (12), which are designed to be at least partially flexible. Also provided is a plurality of connecting elements (18) for connecting the upper part (10) and the lower part (12), the connecting elements (18) being spaced apart along a longitudinal extent (8) of the wiper blade (2) and being attached to the upper part (10) and/or the lower part (12) by a rotary joint, and the connecting elements (18) being designed to allow a motion of the upper part (10) and the lower part relative to each other with a motion component along the longitudinal extent (8) of the wiper blade (2). The window-wiping device also has a wiper-blade-side fastening part (30), which is accommodated in the wiper blade head (70), and a fastening element (50), which can be attached to the drive shaft (33) and into which the wiper-blade-side fastening part (30) can be locked and which has an actuating device (21), which is designed to release the wiper-blade-side fastening part (30) from the fastening element (50) as a result of an actuation, wherein the actuating device (21) has a blocking element (22), which is designed to block actuation of the actuating device (21).

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 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.

The invention relates to a wiper (2) of a window of a motor vehicle, comprising a wiper portion (12) and a connection portion (14) to a drive mechanism (4, 6) of the wiper, said wiper portion comprising a supporting element (16) that is attached to a wiper blade (20) of the window and that contains a stiffening element (18) of the wiper. According to one feature of the invention, the connection portion (14) is arranged as an extension of a proximal axial extremity (8) of the wiper portion.
