An automobile vehicle wiper arm system includes a wiper arm base rotatably connected to a fixed structural member. A wiper arm extension is slidably disposed to the wiper arm base during wiper arm base travel about an arc of travel. A motion link is rotatably connected to the wiper arm extension and is rotatably connected to the fixed structural member. The motion link induces the wiper arm extension to outwardly displace and inwardly displace opposite to the outward displacement during wiper arm base rotation about the arc of travel. A wiper blade is connected to the wiper arm extension and traverses an oval-shaped travel arc along a vehicle windshield by the slidable displacement of the wiper arm extension during wiper arm base rotation. A linkage group connects the wiper arm extension to a wiper motor with rotation of the wiper arm base induced by operation of the wiper motor.

A vehicle cleaning system is provided including a foreign object detection section configured to detect a foreign object present on a windshield, a foreign object removal device configured to clean the windshield to remove the foreign object, an actuation notification section configured to notify a user of actuation of the foreign object removal device, and a control section that, when the foreign object detection section has detected the foreign object, controls the actuation notification section so as to notify of actuation of the foreign object removal device before controlling the foreign object removal device so as to clean the windshield.

A vehicle wiper device includes a first driving lever, a second driving lever, a first driven lever, a second driven lever, a first wiper arm, a first wiper blade, a second wiper arm, and a second wiper blade. The first driving lever is pivoted by a driving force of a first drive source. The second driving lever is pivoted by a driving force of a second drive source. A pivoting speed of the second wiper blade from a lower reversal position is set to be greater than a pivoting speed of the first wiper blade from a lower reversal position.

A first driven lever of a vehicle wiper device has a proximal end pivotally connected to a distal end of a first driving lever. A second driven lever has a proximal end pivotally connected to a distal end of the first driven lever and a distal end pivotally connected to a distal end of a second driving lever. A first wiper arm operates integrally with the second driven lever and has a distal end to which a first wiper blade is connected. A swing transmission mechanism transmits a driving force to the first driving lever. The swing transmission mechanism includes a swing crank arm integrally rotatable with a rotation shaft of a single drive source. An extension-contraction transmission mechanism transmits a driving force to the second driving lever. The extension-contraction transmission mechanism includes an extension-contraction crank arm integrally rotatable with the rotation shaft of the drive source.

The invention relates to a device (2) for wiping a window of a motor vehicle, comprising a wiper blade (4) rotated by a drive shaft (6) which is arranged at the output of a motor assembly (8) capable of creating an alternating rotational movement of said drive shaft. The wiping device also comprises means for translating the motor assembly, and some of said drive means are supported by the drive shaft. In this way, it is the rotation of the drive shaft that translates the motor assembly. The invention also relates to a motor vehicle comprising such a wiping device and to a structural element, in particular a boot door, to which the device is attached.

A window washer having a brushing arm mounted to a wiping arm of the window washer, and a motion conversion mechanism for converting back and forth rotational motion of the wiping arm to back and forth linear motion of the brushing arm, thereby the brushing arm rotates with the wiping arm motion, and in addition, linearly slides back and forth from the wiping arm, for brushing a window.

This invention relates to a vehicle wiper unit (1) providing a safer and more comfortable drive to the drivers as a result of sweeping away with an increased sweeping area to weep accumulated rain and snow on the glass (4) of windshield and rear window (4) of any kind of land, air and marine vehicles. During sweeping wiper blade (5) makes a reciprocating motion on the window (4) in a linear direction by means of an actuator (3) situated within the vehicle wiper unit (1). Therefore a wider area is swept on vehicle window (4).
