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.

A vehicle wiper device includes a wiper arm, a wiper blade, a nozzle body, a hose, and a cleaning fluid supply section. A leading end side portion of the wiper arm is configured by an arm piece, and the wiper arm swings back and forth. The nozzle body is attached to the arm piece, is disposed on an outward movement side of the wiper blade, and jets cleaning fluid toward a windshield. The hose conveys cleaning fluid under pressure. The cleaning fluid supply section is at an opposite side of a rubber holder from the windshield, extends from the nozzle body so as to extend across the rubber holder from the outward movement side toward a return movement side of the wiper blade, is connected to the hose, and supplies cleaning fluid to the nozzle body.

A windscreen wiper device of the flat blade type having an elastic, elongated carrier element and an elongated wiper blade of a flexible material, adapted to be placed in abutment with a windscreen to be wiped. The wiper blade includes at least one longitudinal slit, in which at least one longitudinal strip of the carrier element is disposed. The windscreen wiper device comprises an oscillating arm having a rod-like extension, a connecting device and a nozzle for spraying a washing liquid onto the windscreen to be wiped. The connecting device includes a channel adapted to receive a free end of the rod-like extension. The nozzle is adapted to be mounted onto the rod-like extension. The nozzle and the connecting device are provided with mutually cooperating protrusion/groove means for locking the nozzle onto the connecting device upon insertion of the free end of the rod-like extension inside the channel of the connecting device.

A windscreen wiper device of the flat blade type is provided. The windscreen wiper device includes a connecting device for a rod-like extension of an oscillating arm. The rod-like extension can be pivotally connected to the connecting device about a pivot axis near one end thereof. The connecting device comprises a channel arranged to receive the rod-like extension. The channel includes a first chamber facing towards an entrance of the channel, as well as a second chamber facing away from the entrance. The first chamber has a larger width than the second chamber. The first chamber is arranged to receive a first part of the free end of the rod-like extension. The second chamber is arranged to receive a second part of the free end of the rod-like extension. The first part of the rod-like extension has a larger width than the second part of the rod-like extension

A wiper unit for an automobile windshield wiper system has at least one wiper arm connectable to a wiper drive of the windshield wiper system and at least one wiper blade supported by the wiper arm. In order to provide a lightweight wiper unit that can be produced cost-effectively and offers greater design freedom, at least one fiber-reinforced nonmetallic strip is arranged on the outside of the wiper arm and/or the wiper blade. That nonmetallic strip extends over at least half the length of the wiper arm or wiper blade, is connected to the wiper arm or the wiper blade in a substance-bonded manner, and is arranged at least in part on a side of the wiper arm or wiper blade which is arranged facing or facing away from an automobile windshield which is to be wiped.

A windscreen wiper arm, particularly for automobiles, that is able to oscillate upwardly and downwardly between a downward position and an upward position. The windscreen wiper arm comprises a wiper arm member having a substantially U-shaped cross-section, as well as a wiper rod. The wiper arm member at one end is adapted to be pivotally connected to a mounting head mounted on a drive shaft. The wiper arm member at another end is rigidly connected to the wiper rod. The wiper rod at one end extends inside the U-shaped cross-section of the wiper arm member, and the wiper rod at another end is rigidly connected to an adapter adapted to be connected to an elongated wiper blade to be placed in abutment with a windscreen to be wiped. The adapter, at the location of its connection to the wiper blade, has a U-shaped cross-section with a base and two spaced-apart legs. The U-shaped cross-section is mounted offset in a plane of the base relative to a longitudinal axis of the wiper rod. The windscreen wiper arm is provided with a nozzle for spraying a washing liquid onto the windscreen to be wiped. The nozzle is detachably connected to the adapter at a lateral side of the windscreen wiper arm facing towards the upward position.

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.

Wiper blade mounting assemblies are disclosed. In embodiments, the wiper blade mounting assemblies include an arm subassembly configured for attachment to a wiper blade mounting arm, and a wiper blade sub-assembly configured to attach to a wiper blade. The arm and wiper blade sub-assemblies may be configured to couple across a swivel coupling that is configured to permit a pre-determined degree of swivelling of the wiper blade sub-assembly relative to the arm sub-assembly. Methods of mounting wiper blade mounting assemblies and chatter free wipers including such wiper blade mounting assemblies are also disclosed.
