The invention relates to a windscreen wiper device for a vehicle, comprising a wiper blade (2) having an elongate upper part (10) and an elongate lower part (12) which are at least partially flexible. Also provided are multiple connecting elements (18) for connecting the upper part (10) and the lower part (12), the connecting elements being mutually spaced along a longitudinal extent (8) of the wiper blade (2) and being attached to the upper part (10) and/or the lower part (12) by a rotary joint, and the connecting elements (18) being designed to allow a movement of the upper part (10) and the lower part relative to each another with a movement component along a longitudinal extent (8) of the wiper blade (2). The wiper blade (2) has a fastening arrangement (32) which is designed to be fitted into a hollow shaft (40) of a drive unit and to be connected thereto so to transmit a torque from the drive unit via the hollow shaft (40) and the fastening arrangement (32) to the wiper blade (2).

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.

A wiper system for a vehicle is provided. The wiper system includes a driving assembly. The wiper system further includes a supplementary wiper having a first end that is coupled to a first pivot point of the driving assembly. When the wiper system is activated, the driving assembly is configured to swing the supplementary wiper about the first pivot point from a resting position to an extended position. The supplementary wiper is configured to be statically disposed at the extended position to prevent water from passing over one of two A-pillars of the vehicle to a side window of the vehicle. When the wiper system is deactivated, the driving assembly is configured to stow the supplementary wiper back from the extended position to the resting position.

A windshield wiper assembly for a dual sweep angle and indexable wiper system is provided. The system includes a wiper motor and a wiper arm for sweeping a surface of a windshield coupled to a first eccentric, the first eccentric comprising a primary eccentric and an indexable eccentric plate, wherein the indexable eccentric plate determines an eccentric offset of the wiper arm coupled to the first eccentric. The system further includes an output wiper shaft coupled to the wiper arm, a second eccentric coupled to a cam shaft, and a link coupled to the first eccentric and the second eccentric, the link having a first effective link arm length between the first eccentric and the second eccentric for driving the first eccentric to operate the wiper arm when operated in a first direction.

A windshield wiper system (WWS) is provided and includes a brushless direct current (BLDC) motor with a motor output shaft gear, a gear train and an internally cut sector gear. The gear train includes a first gear, which has a first diameter and engages with the motor output shaft gear, and a second gear, which has a second diameter that is shorter than the first diameter and rotates with the first gear. The internally cut sector gear is coupled with an output shaft and formed to define an internal geared groove that engages with the second gear.
