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).

The disclosure is a wiper structure. The main wiper frame includes a fixing seat. A pair of secondary wiper frames is connected to two ends of the main wiper frame. Each secondary wiper frame includes a flexible sheet. The flexible sheet is disposed with sliding troughs. A length of the sliding trough is greater than a width of the sliding trough. Multiple engaging frames are evenly disposed on each secondary wiper frame. Each engaging frame includes a pressing wing and a sliding block. The sliding block includes a neck bar with a passing diameter. The passing diameter is less than the trough width. The sliding block of each engaging frame passes through the opening and abuts against each sliding trough through the neck bar. The sliding block is slidable in each sliding trough with a change of an external force exerted on corresponding one of the secondary wiper frames.

Disclosed is a flat wiper blade that includes: a wiper strip 10 which wipes a wiping surface; at least one guide clip 20 which passes through and is fitted to the wiper strip 10 in a width direction of the wiper strip 10; and a guide spring 30 which is coupled to the wiper strip 10 and the guide clip 20 and supports the wiper strip 10.

The subject-matter of the invention is a water draining cover (1) for an automotive windshield wiping mechanism, containing a positive connection element (4) of the cover, adapted for securing on the body (2) of the shaft (11), containing an opening on the shaft (5) and surrounded by a gutter part (6) containing a drainage opening (7), characterized in that the positive connection element of the cover (4) does not have a continuous rotary symmetry with regard to the X axis, and in each transverse section in the plane perpendicular to the X axis it has the shape of a convex figure, and furthermore the positive connection element of the body (3) has means of blocking the movement of the cover (1) in a direction parallel to the X axis when the cover (1) is mounted on the body (2), preferably in the form of at least one projection and/or recess (9), preferably perpendicular to the X axis, while the X axis is defined as a straight line passing through the opening on the shaft (5), coinciding with the axis of rotation of the shaft (11) when the cover (1) is properly mounted on the body (2). The subject-matter of the invention is also the body (2) of a shaft (11) corresponding to the cover of the invention, as well as an automotive windshield wiper mechanism containing the cover (1) and the body (2).

The invention relates to a windshield wiper device (100) for a vehicle, having a fastening element (32) and a mounting unit (110) configured to be mounted to the fastening element (32), wherein the mounting unit (110) has a first engagement means (116). The windshield wiper device (100) comprises a wiper blade (2) having a longitudinal extension (8), wherein on the wiper blade side, the wiper blade (2) is provided with a fastening part (120) having a second engagement means (124). The mounting unit (110) and the fastening part (120) on the wiper blade side can be inserted into each other, at least partially, by a movement substantially along the longitudinal extension (8) of the wiper blade (2). The first engagement means (116) and the second engagement means (124) are designed to engage with one another, whenever the mounting unit (110) and the fastening part (120) on the wiper blade side are inserted into each other. The engagement between the first engagement means (116) of the mounting unit (110) and the second engagement means (124) of the fastening part (120) on the wiper blade side can be released.

A windshield wiper arm is provided on an outside of an aircraft and positioned to directly engage an air flow while the aircraft is traveling. The wiper arm includes an arm portion coupled to the aircraft and having an arm exterior surface, the arm portion extending along an arm axis and defining an arm length. A bead extends outwardly from the arm exterior surface and defines a bead exterior surface, the bead being sized sufficiently to engage a boundary layer of the air flow. A wiper blade is coupled to the arm portion. The bead prevents separation of the boundary layer from the arm exterior surface, thereby to attenuate shedding of vortices and associated vibrations and noise.

A wiper lever (10) for cleaning a vehicle pane by means of a movement in a first and a second direction is proposed. Said wiper lever comprises a wiper blade (12), a wiper arm (14), an adapter (16) for securing the wiper blade (12) to the wiper arm (14) and a hydraulic system (18) which conducts a liquid from a vehicle to the wiper blade (12) via the wiper arm (14) in order to eject the liquid via nozzles (20) on the wiper blade (12). Said wiper lever comprises at least one nozzle (20) which is oriented in the first direction (1) and one nozzle (20) which is oriented in the second direction. According to the invention, a first valve (221) for the first direction is positioned closer to the nozzles (20) in the direction of flow (3) of the liquid than a second valve (222) for the second direction (2).
