Wiper blade for a wiping system, in particular for wiping a camera of a motor vehicle, the wiper blade comprising a connection device suitable for releasable connection to a drive shaft of the wiper blade, said connection device comprising a first orientation which allows mounting/dismounting relative to a drive shaft, and a second orientation which does not allow such mounting/dismounting.

A windscreen wiper device of the flat blade type comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes at least one longitudinal slit, in which slit at least one longitudinal strip of the carrier element is disposed, which windscreen wiper device comprises a connecting device for a rod-like extension of an oscillating arm, wherein said rod-like extension can be pivotally connected to said connecting device about a pivot axis near a free end thereof, with the special feature that said connecting device comprises a channel arranged to receive said free end of said rod-like extension, wherein said windscreen wiper device comprises a nozzle for spraying a washing liquid onto said windscreen to be wiped, wherein said nozzle being mounted onto said rod-like extension, and wherein said rod-like extension at a side facing towards said connecting device extends in longitudinal direction beyond said nozzle.

A stepped-designed beam arm wiper assembly has a beam arm that locks into a mounting head such that the beam arm can be disconnected from the mounting head for servicing a wiper blade attached to the beam arm. A head cover is attached to the mounting head via hinges on either side of the head cover which allow the head cover to open off the head on either pin hinges of the head, and can be pressed onto the head and retained on. The other end of the beam arm is inserted into an adapter which snaps onto a rear wiper blade coupler via lead-in hole and trunnion connection. The beam arm has an airfoil with a stepped design to match the head cover, adapter, and blade assembly stepped design.

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.
