A windscreen wiper device is provided. The windscreen wiper device includes an elongated wiper strip of a flexible material for sealing against the windshield and at least one elongated groove. At least one flexible and elongated carrier element is disposed in the at least one groove of the wiper strip for biasing the wiper strip into a predetermined configuration when in a relaxed state. The at least one carrier element presents at least one upwardly facing curve and at least one downwardly facing curve when in a relaxed state.

The present invention relates to a device including a wiper blade having a length measured from a first end of the wiper blade to a second end of the wiper blade that is adjustable without removal of material of the wiper blade and a housing removably connected to the wiper blade. The present invention also relates to a method of adjusting a length of a wiper blade including providing a wiper blade having a first length and adjusting said wiper blade to have a second length different than the first length without removal of material of the wiper blade.

A streamlined windscreen wiper comprises a longitudinal streamlined fairing comprising a central mounting and at least one end cap, at least one adapter element fixed to the central mounting and comprising a central web and two legs extending substantially perpendicularly from opposing edges of said central web, one of said at least one end caps being articulated to said adapter element, and a retention means comprising at least one rib extending from a lower surface of the central mounting and oriented substantially perpendicularly to the central web of the adapter element, and a window provided in the central web of the adapter element, the window being engaged by the at least one rib.

A lever is made of resin and constitutes a part of a wiper lever assembly that supports a blade rubber. The lever includes a coupling part having a coupling shaft to be coupled to a wiper arm. Further, the lever includes a pair of arm parts composed of a first arm part and a second arm part extending in mutually different directions from the coupling part. In addition, the lever includes a convex part protruding from the coupling part, formed at a center part between an end part of a first arm part opposite to the coupling part and an end part of a second arm part opposite to the coupling part.
