A windscreen wiper device, particularly for automobiles, comprising an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, the wiper blade comprising a connecting device for an oscillating arm, wherein the oscillating arm near one end thereof is pivotally connected to the wiper blade (2) and near the other end thereof is connected to a mounting head on a drive shaft for transferring a reciprocal movement to the wiper blade, wherein the windscreen wiper device further comprises a cap detachably connected to the mounting head at the location where the oscillating arm is connected to the mounting head, wherein the cap is snapped onto an outer wall of the mounting head in axial direction thereof, with the special feature that the cap comprises at least one resilient, downwardly extending tongue having a hole, wherein the outer wall of the mounting head comprises a laterally outwardly extending protrusion engaging in the hole of the tongue, and wherein the resilient tongue is hingeable along an hinge axis between an inward position retaining the cap onto the mounting head and an outward position releasing the cap from the mounting head.

A wiper arm including an arm head having an arm head body and cover member. The cover member is attached to the arm head body and can open and close. The mechanical strength of the arm head can be increased. The arm head includes a head cap which is rotatably attached to rotating shafts and provided on the inner side surfaces of both side sidewalls of an aim head body. When the head cap is in its closed position, a front-side half section of the head cap is disposed between both side sidewalls. On the rear surface of a rear-side half section of the head cap, a cylindrical cap-side fitting section is provided and fits with a nut disposed on the arm head body. The cap-side fitting section includes slits and is formed so that the height in its vertical direction decreases in a front-side portion.

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 windscreen wiper device, particularly for automobiles, comprises an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade is of the flat blade type and includes at least one groove, in which groove an elastic, elongated carrier element is disposed, wherein the windscreen wiper device further comprises a mounting head for transferring a reciprocal movement to the wiper blade, with the special feature that the windscreen wiper device further comprises a longitudinal strip-shaped arm, wherein the arm near a first end thereof is directly connected to the mounting head and near a second end thereof is directly connected to a connecting device of the wiper blade, and wherein the arm made of a resilient material is biased in order to exert a pressure onto the wiper blade towards the windscreen to be wiped.

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.
