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 system including wiper blades with different lengths may include: an arm to be rotated, and a blade to be rotated with the arm. In particular, the arm includes a retainer to press the blade, and the blade includes: a primary coupled to a front end of the retainer; and a plurality of yokes coupled to the primary and to receive a transferred pressing force and to transfer the pressing force to a bertebra coupled to a lower side thereof.

A wiper arm device for a wiper arm (20), having at least one fastening part (44) which is provided for connecting at least one articulation part (38) of the wiper arm (20) to a drive shaft (24) of a wiper drive (16), wherein the fastening part (44) has at least one fastening boss (46) for fastening the fastening part (44) to the drive shaft (24) and at least one articulation boss (48) for fastening the articulation part (38) to the fastening part (44).

A wiper device including a wiper member that includes a wiper arm to which a wiper blade is coupled, a base end portion of the wiper arm being supported by a support section provided at a vehicle, and the wiper member being configured to of undergo displacement relative to the vehicle, a drive wheel that is rotatably supported by the wiper member at a position of the wiper member which is separated from the support section, and that rolls across a running face provided at the vehicle so as to displace the wiper member relative to the vehicle, and a motor that is supported by the wiper member so as to undergo displacement together with the wiper member, and that drives rotation of the drive wheel.

A wiper device includes a pivot shaft, a pivot holder, a water receiving cap and a washer. The pivot holder includes a pivot support portion and a mounting leg. The pivot support portion pivotally supports the pivot shaft. The water receiving cap includes a boss portion and an umbrella portion. The boss portion is fitted onto the pivot support portion. The washer is fixed to a circumference of the pivot shaft at a portion projecting from a distal end of the pivot support portion. At least part of the boss portion overlaps the washer in an axial direction. The umbrella portion includes a projection that projects in the axial direction. The projection opposes the mounting leg in a circumferential direction without engaging the mounting leg in the axial direction.

The invention relates to a cap A comprising a first portion 1 that is able to cover a first end of a wiper arm of a wiping system of a vehicle, and a second portion 2 comprising an attachment means for attaching the cap A to the driving arm, characterized in that this attachment means comprises at least one rotation zone 222 that is arranged so as to allow the cap A to rotate with respect to the driving arm, and a zone 223 for locking said cap A to said driving arm.

The invention relates to a wiper arm head (14) for a wiper arm rod (11), with a first end region (178), which has an opening (15) for receiving a drive shaft, and a second end region (179) for the pivotable fastening of the wiper arm rod (11), and with means for directing at least one hose (31, 32) carrying a cleaning fluid. It is provided according to the invention that the means has a feedthrough (181, 182), which leads the hose (31, 32) from an upper side (187) in the direction of an underside (188) of the wiper arm head (14).

The invention relates to an assembly (200) for connecting a windscreen wiper drive arm to a vehicle drive shaft, the connection assembly (200) comprising at least one fixing device (220) configured to rotatably connect the drive arm to the drive shaft and at least one cover (210) mounted pivotably on the fixing device (220) by means of a pivoting connection (600), the cover (210) being configured to adopt a closed position in which it prohibits access to a fixing zone (300) between the fixing device (220) and the drive shaft or an open position in which it permits access to the fixing zone (300) between the fixing device (220) and the drive shaft, this pivoting connection (600) comprising at least one bore and at least one trunnion received in the bore, characterized in that the connection assembly (200) comprises at least one device for locking the open position of the cover (210), this locking device being arranged on the inner perimeter of the bore and on the outer perimeter of the trunnion.

Casing (20) for a windscreen wiper drive rod, in particular of a motor vehicle, said casing being configured to cover at least a portion of said drive rod and comprising means for fixing to said drive rod and/or to at least one element (42) linked to said drive rod, characterised in that it further comprises support and guiding means (70) which are configured to cooperate with at least one electric cable (63) and/or at least one fluid line (64) of said windscreen wiper.

A wiper device includes a pivot shaft, a pivot holder, a water receiving cap and a washer. The pivot holder includes a pivot support portion and a mounting leg. The pivot support portion pivotally supports the pivot shaft. The water receiving cap includes a boss portion and an umbrella portion. The boss portion is fitted onto the pivot support portion. The washer is fixed to a circumference of the pivot shaft at a portion projecting from a distal end of the pivot support portion. At least part of the boss portion overlaps the washer in an axial direction. The umbrella portion includes a projection that projects in the axial direction. The projection opposes the mounting leg in a circumferential direction without engaging the mounting leg in the axial direction.
