A stepped-designed beam arm wiper assembly has a beam arm that locks into a mounting head such that the beam arm can be disconnected from the mounting head for servicing a wiper blade attached to the beam arm. A head cover is attached to the mounting head via hinges on either side of the head cover which allow the head cover to open off the head on either pin hinges of the head, and can be pressed onto the head and retained on. The other end of the beam arm is inserted into an adapter which snaps onto a rear wiper blade coupler via lead-in hole and trunnion connection. The beam arm has an airfoil with a stepped design to match the head cover, adapter, and blade assembly stepped design.

A wiper system for use with a windshield includes a track guide, a wiper assembly, a drive mechanism and a wipe mechanism. The wiper assembly has a wiper arm attached at a first end thereof to a rotor rotatably disposed on a wiper carrier, wherein the wiper carrier is engaged with the track guide and is configured for translation therealong. The drive mechanism is connected with the wiper carrier and is configured for positioning the wiper carrier along the track guide. The wipe mechanism is connected with at least one of the rotor and the wiper carrier and is configured to cause the rotor to rotate, thereby causing the wiper arm to produce a wiping motion.

An electromagnetic wiper system for a windshield of a vehicle includes a linear actuator, a wiper-arrangement, and control circuitry. The linear actuator includes at least one guide rail having permanent magnets and an electromagnetic moving block. The electromagnetic moving block includes at least one perforation that surrounds the at least one guide rail and at least one electromagnetic coil that surrounds the at least one perforation. The wiper-arrangement includes a wiper arm and a wiper blade, wherein at least the wiper arm is coupled to the electromagnetic moving block. The control circuitry controls a linear motion of the electromagnetic moving block along the at least one guide rail to steer the wiper arm that is coupled to the electromagnetic moving block back and forth across a length of the windshield to the windshield, wherein the electromagnetic moving block induces minimal friction during the linear motion.

The present invention comprises an AS-side wiper motor 40 including an AS-side output shaft 83 that is rotated in forward and backward directions and a link mechanism 60 constituted by a four-bar link. The AS-side wiper member 50 is configured to wipe in a first AS-side wipe range 11b by a pivotal movement of the AS-side output shaft 83 in a first angular range SA1, and wipe in a second AS-side wipe range 11c by a pivotal movement of the AS-side output shaft 83 in a second angular range SA2 that differs from the first angular range SA1. The wipe range of the AS-side wiper member 50 can thus be switched between the first AS-side wipe range 11b and the second AS-side wipe range 11c by controlling an angular range, in which the AS-side output shaft 83 is pivotally moved, to be in the first angular range SA1 or the second angular range SA2 that differ from each other. In addition, a size of the wipe range can be adjusted by controlling a pivot angle of the AS-side output shaft 83 in forward and backward directions.

When an operation signal of a view-obstructing material removal mode switch has been detected, a controller controls such that wiping operation is performed while spraying washer fluid toward the opposite side to a movement direction side of a wiper blade, after which a wiping operation in which washer fluid is not sprayed is performed.

A vehicular wiper device is provided with a snowfall determination unit that determines whether a predetermined snowfall condition is satisfied. When the snowfall determination unit determines that a predetermined snowfall condition is satisfied, a controller that controls a wiper motor changes lower reverse positions of wiper blades to lower reverse positions during snowfall that are on the lower side with respect to lower reverse positions during normal times.

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.

The invention concerns a windscreen wiper device (2; 28, 30; 74; 78) for a vehicle, in particular a motor vehicle. The windscreen wiper device (2; 28, 30; 74; 78) comprises an elongate upper part (10) which is designed to be at least partially flexible. It further comprises an elongate lower part (12) which is designed to be at least partially flexible. Further present are a plurality of connection elements (18) for connecting the upper part (10) and the lower part (12), the connection elements (18) being disposed at spacings from each other along a longitudinal extension (8) of the windscreen wiper device (2; 28, 30; 74; 78) and secured to the lower part (12) by means of swivel joints (20; 122, 130).
