An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a distal end of the wiper arm, and a drive shaft coupled to a proximal end of the wiper arm. The wiper blade is configured to clean water, dirt, and other debris from the windshield of the aircraft. The drive shaft is configured to rotate and cause the wiper arm with the coupled wiper blade to sweep across the windshield. The wiper arm includes both composite and metal components to reduce the weight of the windshield wiper system while also providing lightning strike protection.

The invention relates to a wiper arm (10) for a wiper system of a vehicle, having a wiper arm element (12) which is configured for connecting, in an articulated manner, an attachment piece (20) coupled to a wiper shaft, wherein the wiper arm element (12) is coupled to an adapter element (18) for connecting to a wiper blade. Furthermore, it is provided that the wiper arm element (12) consists of two separate components (14, 16), namely a first component (14), which is connected to the adapter element (18), and a second component (16), which attaches to the first component (14) on the side facing away from the adapter element (18), and that the first component (14) is formed from a profile strip (37) having a U-shaped cross section, wherein the two components (14, 16) overlap in a longitudinal direction in a first connection area (24).

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.

A wiper apparatus which removes foreign matters from a windshield by rotating by a pivot of a vehicle may include an arm piece connected to one end of an arm retainer to connect a wiper blade, and a coupling portion having a step portion formed to extend along a longitudinal direction so that an upper surface of the arm piece and an upper surface of the arm retainer form a same surface when coupled to correspond to a coupling hole formed in the arm retainer.

The wiper device includes a carrier element and a wiper blade with at least one longitudinal groove, in which groove the carrier element is disposed. The wiper device also includes a connecting device for pivotally connecting the wiper blade with an oscillating arm. The connecting device has spaced-apart sidewalls, each with a protrusion that extends sidewardly and outwardly. The connecting device and oscillating arm are interconnected by the protrusions pivotally and snappingly engaging into correspondingly shaped recesses of the oscillating arm. The oscillating arm has a guiding tongue engaging into a guiding groove of the connecting device. 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.

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.
