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 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 moveable drive arm fastener is positioned at one of a plurality of moveable drive arm fastening positions. The wiper blade assembly is connected to the curved cantilever beam with a wiper blade fastener positioned at a wiper blade assembly fastening position on an outboard tip of the curved cantilever beam. The curved cantilever beam has an effective length extending from the moveable drive arm fastener to the wiper blade assembly fastener such that a blade load exerted by the curved cantilever beam on the wiper blade assembly is a function of the effective length

A wiper assembly may include a wiper blade comprising: a blade element; and a support element secured to the blade element along a blade element length of the blade element. A wiper assembly may include a flat spring coupled on a first end to a first end of the support element via a first coupling and coupled on a second end to a second end of the support element via a second coupling. A wiper assembly may include a saddle clip disposed between the first end of the support element and the second end of the support element and configured to couple the flat spring to the support element, wherein a downward biasing of the saddle clip causes the wiper assembly to bias against the windshield.
