The present invention relates about a wiper system for cleaning a vehicle window, comprising a drive attachment, an arm, a wiper blade and a connecting body located between the drive attachment and the arm, the wiper system comprising a pivot link between the connecting body and the drive attachment, the wiper system comprising a rotational link between the connecting body and the arm, the rotational link having an axis that extends along a first direction, the pivot link having an axis that extends along a second direction, said first direction and said second direction being intersected, wherein the wiper system comprises a mechanical link between the drive attachment and the arm enforcing a rotation of the pivot link around the second direction upon a rotation of the arm around the first direction.

The present invention proposes a wiper system being capable of ensuring wiping quality for the windshields with complex surfaces. The wiper system comprises: a wiper arm (19), on which a wiper blade (12) for cleaning a surface (16) of an object to be cleaned is provided; a first electrical motor (1) driving the wiper arm (19) to swing; a second electrical motor (9); a sensor (13) measuring a parameter representing the position of the wiper arm on the object to be cleaned; a control unit (7) receiving said parameter from said sensor (13) and utilizing said parameter to control the rotation angle of the an output shaft (18) of the second electrical motor (9), such that the output shaft (18) drives rotate the wiper blade (12) under control to change the rotation angle of the central plane of the wiper blade with respect to the wiper arm. The present invention also proposes a vehicle comprising said wiper system.

A wiper system (10), comprising a wiper arm (12) having a geometrical axis of rotation (x), a connecting arrangement (14) configured to connect the wiper arm to a motor-driven rotating shaft (100), wherein the connecting arrangement is configured to transfer the rotating motion of the shaft into a rotating motion of the wiper arm about said geometrical axis of rotation, a spring arrangement (24) configured to resiliently press the wiper arm against the connecting arrangement in the axial direction, and a tilting arrangement (30) configured to vary the inclination of the pressed wiper arm relative to said geometrical axis of rotation based on the rotational position of the wiper arm about said geometrical axis of rotation. There is also provided a vehicle comprising such a wiper arm system.

A wiper device including a wiper member that includes a wiper arm to which a wiper blade is coupled, a base end portion of the wiper arm being supported by a support section provided at a vehicle, and the wiper member being configured to of undergo displacement relative to the vehicle, a drive wheel that is rotatably supported by the wiper member at a position of the wiper member which is separated from the support section, and that rolls across a running face provided at the vehicle so as to displace the wiper member relative to the vehicle, and a motor that is supported by the wiper member so as to undergo displacement together with the wiper member, and that drives rotation of the drive wheel.

A windshield wiper system has an articulating pivot for wiping a curved glass surface of a vehicle. The articulating pivot has a pivot shaft assembly (64) having a first pivot ball (160) separated by a distance from a second pivot ball (166). The pivot shaft assembly is encased in an outer housing (158) and each pivot ball is supported by a bearing. A pinion gear is integrated with one of the first pivot ball, the second pivot ball, and/or the pivot shaft. A rack gear is integrated into one of the bearings and/or the housing. Rotational movement of the pinion gear along the rack gear articulates the pivot shaft as the pivot shaft is rotated.

The present invention relates to a pantographic-type wiper system for cleaning a vehicle window that includes a drive attachment, a first arm, a second arm and a head configured to hold a wiper blade, where the first arm extends between the drive attachment and the head, where the second arm extends between a holding device attached to the drive attachment and the head, also characterized in that the wiper system includes a connecting body that links the first arm to the drive attachment and where the wiper system includes a pivot link (P) between the connecting body and the drive attachment and includes a rotational link (D) between the connecting body and the first arm; the wiper system also including at least a rotational device that allows motion around a first axis (A) that corresponds to a main elongation axis of the second arm between the head and the second arm or between the holding device and the second arm.

A wiper system (10), comprising a wiper arm (12) having a geometrical axis of rotation (x), a connecting arrangement (14) configured to connect the wiper arm to a motor-driven rotating shaft (100), wherein the connecting arrangement is configured to transfer the rotating motion of the shaft into a rotating motion of the wiper arm about said geometrical axis of rotation, a spring arrangement (24) configured to resiliently press the wiper arm against the connecting arrangement in the axial direction, and a tilting arrangement (30) configured to vary the inclination of the pressed wiper arm relative to said geometrical axis of rotation based on the rotational position of the wiper arm about said geometrical axis of rotation. There is also provided a vehicle comprising such a wiper arm system.

A windshield wiper scrubbing device for cleaning a windshield is disclosed. The windshield wiper scrubbing device comprises an arm comprising a top side and a bottom side. The arm moves in a first and second vertical direction. The bottom side of the arm comprises a scrubbing rod that moves in a first and second horizontal direction. A liquid canister releases cleaning solution onto the windshield upon a first actuation of a switch. A scrubbing pad located on the scrubbing rod is placed onto the windshield through a first rotation in a first rotational direction after the windshield receives the cleaning solution. A scraper located on the bottom side of the arm is placed onto the windshield through a second rotation in a second rotational direction upon a second actuation of the switch. A motor powers the scrubbing rod and rotates in the first rotational direction and the second rotational direction.
