A connecting structure of a wiper arm includes a connecting shaft provided on a wiper arm and a snap-fit provided on a wiper blade. The snap-fit includes a pair of claws defining a groove that can be engaged with the connecting shaft. A slit defined by inner walls facing each other is provided on both sides of the pair of claws in a longitudinal direction of the wiper blade. A first protrusion protruding toward inside of the slit is provided on one of the inner walls, and a second protrusion protruding toward inside of the slit is provided on the other of the inner walls. The first and second protrusions are arranged offset from each other in a direction along an axial direction of the connecting shaft.

The windscreen wiper device includes a wiper element which is made of a flexible material and a carrier which operably supports the wiper element and biases the wiper element into a pre-curved position. A base is engaged with the carrier and at least one connector piece is releasably connectable with the base. The base includes a pair of holding elements which wrap around opposite lateral side edges of the carrier and a pair of laterally spaced side walls. The connector piece includes a pair of legs. A pair of projections are disposed in at least one of the side walls of the base and the legs of the connector piece and a pair of recesses are disposed on at least one of the side walls of the base and the legs of the connector piece for snappingly receiving the projections to releasably attach the connector piece with the base.

A windscreen wiper device of the flat blade type, particularly for automobiles, 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 groove, in which groove a longitudinal strip of the carrier element is disposed, which wiper blade comprises a connecting device for an oscillating arm, wherein the oscillating arm near one end thereof is pivotally connected to the wiper blade 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, with the special feature that the connecting device comprises at least two opposing spaced-apart sidewalls each comprising a protrusion extending sidewardly and outwardly, wherein the connecting device and the oscillating arm are interconnected by the protrusions pivotally and snappingly engaging into correspondingly shaped recesses of the oscillating arm, wherein the oscillating arm comprises a downwardly extending guiding tongue engaging into a guiding groove of the connecting device defined between the sidewalls thereof, and wherein the connecting device has an asymmetric form with respect to its middle transverse plane, seen in vertical direction, in order to ensure that the wiper blade can only be mounted on the oscillating arm in a predetermined orientation of the wiper blade relative to the oscillating arm.

The first and second protrusions are arranged offset from each other in a direction along an axial direction of the connecting shaft.

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.

The present disclosure relates to a holder for a wiper arm, a wiper assembly and a motor vehicle. The holder includes a body, having two opposite sidewalls extending in the longitudinal direction of the wiper arm, a fixing pin, arranged between the two opposite sidewalls of the body, and a first locking hole and a second locking hole, disposed in the two opposite sidewalls of the body respectively, and extending along concentric circles centred at the centre of the fixing pin, wherein the positions of the first locking hole and the second locking hole in an axial direction are at least partially coincident.

The invention relates to an adapter intended to connect a wiper blade (7) to a drive arm (5) of a wiper system (800) for a vehicle, the adapter (IO0) comprising a head (I) and a body (2), the adapter (IO0) being formed by an upper wall (IO, 20) and two lateral flanks (I la, I lb, 2la, 2lb), the adapter (IO0) comprising a centring means (3) for centring in a vertical direction (Oz) perpendicular to the upper wall (IO, 20), characterised in that the centring means (3) is extended longitudinally by a guide member (9) configured to be engaged with the drive arm (5), the adapter (IO0) comprising a tab (4) configured to wedge the adapter (IO0) in the vertical direction (Oz). The invention is applicable to motor vehicles.

Related are a wiper-fastening apparatus, a wiper blade assembly, and a wiper device. The wiper-fastening apparatus configured to fasten a wiper arm coupling adaptor to a wiper blade includes a base attached to or detached from a clamp fixed to the wiper blade and on which the adaptor is mounted to be hinge-rotated. Here, the base includes a hinge portion which is hinge-coupled to the adaptor and a lateral portion extending downward from both sides in a width direction of the hinge portion and inside which the wiper blade is mounted. Also, the lateral portion includes a protruding portion biased from the clamp or held by the clamp in a vertical direction depending on an angle formed by a longitudinal direction of the wiper blade and a longitudinal direction of the hinge portion.
