The invention relates to a drive mechanism and a wiper system for a vehicle. The mechanism comprises a coupling member (22), a drive head (10) having means (20) for connecting to a wiper blade arm (48) and a slide (32) arranged so as to rotatably engage the member with the head when a value of a torque applied to the head relative to the member is less than a predetermined threshold, and, when this is not the case, to rotatably disengage the member and the head by sliding in a direction perpendicular to a rotational axis of the member.

A wiper arm for supporting a wiper blade includes a wiper arm head comprises a recessed splined cup portion having a plurality of angularly adjacent teeth about the internal circumference of the cup portion wherein the cup portion includes a slot. A complementary drive shaft includes a splined head having teeth for mating engagement with the teeth in the wiper arm head. In order to facilitate the alignment therebetween, an integral alignment key is received in the axially aligned slots. The alignment key further includes a lower notched end which abuts against a bottom radial lip of the splined head to prevent the key from moving axially in the slots. As such, the key and the splined head include complementary formations preventing the key from accidentally falling out of the slots.

The invention relates to a wiper blade adapter system with a wiper blade adapter unit (10) and at least two differently formed connecting elements (12, 14, 16), wherein, in a mounted state, the wiper blade adapter unit (10) is coupled to one of the at least two connecting elements (12, 14, 16). According to the invention, the wiper blade adapter unit (10) comprises a transmission unit (20) which is provided to release a coupling between the at least one connecting element (12, 14, 16) and the wiper blade adapter unit (10) during a detachment process.

There is provided a wiper arm including a head cover attached to an arm head and securely preventing the head cover from coming off the arm head. A wiper arm (1) includes an engaging protrusion (19) which extends upward and is disposed on a step section (18) formed at a lower end of a dent section (17) formed on a side surface of an arm head (2), and a protruding engagement section (27) formed near a lower end of an inner surface of a side wall (23) of a head cover (4). An opening section (27A) opening downward is formed in the protruding engagement section (27). The engaging protrusion (19) fits into the opening section (27A) along a vertical direction, namely, a direction along the side wall (23). The open end of the side wall (23) of the head cover (4) is thereby prevented from being widened outward so that the head cover (4) is prevented from coming off the arm head (2).

A windscreen wiper arm, particularly for automobiles, includes a mounting head mountable on a drive shaft and an arm member pivotally connected to the mounting head by means of a pivot pin. The arm member has a substantially U-shaped cross-section near the pivot pin comprising two side walls. A part of the mounting head extends between the side walls and beyond the pivot pin. The part is provided with opposite surfaces each facing towards a respective side wall of the arm member. Each surface of the part of the mounting head is positioned spaced-apart from its respective side wall of the arm member, so as to allow paint to enter a space defined between each surface of the part of the mounting head and its respective side wall of the arm member.

The windscreen wiper device includes a wiper blade that extends lengthwise in a longitudinal direction. A pre-curved carrier element with opposing lateral edges biases the wiper blade into a curved shape. At least one projection of a connector base is received in at least one notch of the carrier element for restricting relative longitudinal movement between the connector base and the carrier element. The connector base also at least one long locking arm and at least one short locking arm which engage around the lateral edges of the carrier element to lockingly connect the connector base with the carrier element. The at least one short locking arm has a lateral width which is less than the at least one long locking arm. The at least one short locking arm has a ramped lower surface for allowing the at least one short locking arm to snappingly engage the carrier element.

A wiper device for cleaning a vehicle window is disclosed. The wiper device has a wiper arm fastened in a torque-proof manner to a wiper shaft via an articulation piece, where the wiper arm is arranged pivotably on the articulation piece, a wiper blade arranged on the wiper arm, and a washing device for the wiper blade, which contains a feed for a washing fluid, where the feed runs in a partial region in the longitudinal axis of the wiper shaft and leads to the wiper blade in a direction running substantially perpendicularly to the longitudinal axis.

The invention relates to a window-wiping device for a vehicle having a fastening element fastened to a drive shaft, in particular a motor vehicle. The window-wiping device comprises a wiper blade having an elongate upper part, which is at least partially flexible, an elongate lower part, which is at least partially flexible, a plurality of connecting elements for connecting the upper part and the lower part, wherein the connecting elements are spaced apart from each other along a longitudinal extent of the wiper blade, and wherein the connecting elements are designed to enable a motion of the upper part and of the lower part in relation to each other with a motion component along a longitudinal extent of the wiper blade, and a wiper-blade-side fastening part, wherein the wiper-blade-side fastening part can be detachably connected by means of a linear motion on the fastening element, and the wiper-blade-side fastening part can be connected to the fastening element in such a way that a rotational position about an axis perpendicular to the longitudinal extent of the wiper blade and perpendicular to the linear motion is defined by a support and a further contact point.

The invention relates to a windshield wiper device (100) for a vehicle, comprising a wiper blade (2) having an elongated upper part (10) and an elongated lower part (12), which are configured to be flexible, at least in part. Furthermore, the device comprises a plurality of connecting elements (18) for connecting the upper part (10) and the lower part (12), which are spaced apart from each other along a longitudinal extension (8) of the wiper blade (2), and which are configured to allow a movement of the upper part (10) and the lower part relative to one another with a motion component along a longitudinal extension (8) of the wiper blade (2). The windshield wiper device (100) further comprises a fastening device. The fastening device comprises a wiper-blade-side fastening part (20) and a fastening element (50). The wiper-blade-side fastening part (20) and the fastening element (50) are configured in such a manner that, by means of rotation of the wiper-blade-side fastening part relative to the fastening element, an engagement can be formed in order to fix a position of the wiper-blade-side fastening part relative to the fastening element.
