The invention is based on a windshield wiper device, in particular a wiper arm adapter device, having at least one fluid connection piece (36) which delimits at least one fluid channel (38), and having at least one adapter piece (40), wherein the adapter piece (40) and the fluid connection piece (36) are constructed to be able to be moved relative to each other and are provided to be moved relative to each other during a coupling or uncoupling operation, in particular with a wiper blade (16).

It is proposed that the windshield wiper device comprise at least one coupling unit (42) which is provided to close the fluid channel (38) in accordance with a position of the adapter piece (40) relative to the fluid connection piece (36).

A wiper blade (10), in particular for a motor vehicle, is proposed. It comprises a wiper bar (12) and a coupling element (14) which comprises a coupling connection piece (26) for coupling a fluid channel (22). The coupling connection piece (22) is constructed to be at least partially flexible.

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 multifunction windshield wiper includes a wiper arm, a wiper blade holder, and a wiper blade to facilitate, through channels, the direct distribution of the liquid or an air on the windshield surface. The direct distribution of the liquid and an air maximize the wiping effect and minimizes their usage. The wiper arm is assembled with wiper blade holder within the flexible spherical joints to refine the contact with a curved surface during the operational movement of the windshield wiper in the different weather conditions. The windshield wiper arm has a flexible joint with the link arm to facilitate the tension on the windshield surface during the wiping process.

The invention relates to a wiper arm apparatus (10) for motor vehicles, having a wiper arm head (12), which comprises a drive lever (18), which can be connected to a drive shaft (20), whereby an intermediate lever (22) pivotally supported on the drive lever (18) cooperates with a control lever (24), which control lever (24) is arranged pivotably about a shaft (26) on the side facing away from the intermediate lever (22), and with a fastening device (30; 30a) for at least one hose (1, 2) for supplying a cleaning fluid to a wiper arm (14).

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.

A wiper assembly (100) is provided, comprising a wiper arm (110), a wiper blade (120), and a coupling device (130) configured to enable connection of the wiper blade (120) to the wiper arm (110), wherein the coupling device (130) comprises a first part (140) being connected to one of said wiper arm (110) or said wiper blade (120), and a second part (150) being connected to the other one of said wiper arm (110) or said wiper blade (120). The first part (140) comprises an engaging section (142) being configured to provide an axial fixation of the first part (140) relative the second part (150), and at least one recess (144) configured to provide a rotational fixation of the first part (140) relative the second part (150), and wherein the second part (150) comprises a receiving section (152) configured to receive the engaging section (142) of the first part (140), a locking device (160) arranged radially outwards of said first part (140) and comprising at least one radial protrusion (162) configured to fit with said recess (144) of the first part (140), and a wall (170) surrounding said locking device (160), wherein said wall (170) comprises a constricted section (172) whereby an inner wall (174) of said constricted section (172) is configured to press the radial protrusion (162) radially inwards when the constricted section (172) is axially aligned with the radial protrusion (162).

A contaminant removal apparatus for windshields includes: driving belts located at both side surfaces of a windshield; a drive unit configured to apply driving force to the driving belts; a wiper assembly located on the windshield; rotary rollers configured to be shifted along the driving belts; idle gears located at ends of the driving belts to change a rotating direction of the rotary rollers; frame connection shafts coupled to both ends of the wiper assembly and located within the rotary rollers so as to contact the idle gears to change the rotating direction of the rotary rollers; and a controller configured to change a rotating direction of the rotary rollers when the idle gears and the frame connection shafts contact.

Provided is a windshield wiper arm. This windshield wiper arm includes: an arm head (10); a shank; an arm piece connected to the windshield wiper blade; a washer nozzle which sprays a washer liquid onto the wiping surface; and a hose. The hose is divided into a first hose disposed along the arm head and a second hose disposed within the vehicle body. The first hose and the second hose are connected in a manner that washer liquid can flow from one hose to the other via a joint member (70). The arm head (10) has an opening part (10A) which opens on a fastening part 11 side, and the joint member (70) is mounted to the arm head (10) in a manner that the part of the joint member (70) that connects with the second hose penetrates the opening part (10A).

A wiper arm adapter device with at least one fluid channel (44a, 46a; 44b, 46b) for conducting a fluid, and with at least one connecting unit (48a; 48b) for connecting the fluid channel (44a, 46a; 44b, 46b) to a fluid line element (36a; 36b) of a wiper arm and/or to a wiper blade adapter (30a; 30b), wherein the connecting unit (48a; 48b) has at least one connecting element (52a, 54a; 52b, 54b) which at least partially delimits the fluid channel (44a, 46a; 44b, 46b). The connecting unit (48a; 48b) has at least one valve element (56a, 58a; 56b, 58b) which is arranged on the connecting element (52a, 54a; 52b, 54b) and is configured to form the fluidic connection of the fluid channel (44a, 46a; 44b, 46b) to the wiper blade adapter (30a; 30b) in a closeable manner.
