A window wiper assembly for cleaning a surface of a vehicle window, which includes a guide rail mountable to a frame member supporting the window, a wiper arm having an elongate body configured with an opening and integrally connecting to a head portion for mounting thereto wheel assemblies capable of traversing interiorly within the guide rail, a glide post having a wheeled portion for slidably interacting with an integrated rail associated with the opening, a wiper blade assembly mounted to a bottom side of the elongate body, and a pivot arm equipped with first and second mount fittings respectively connecting to a shaft of the glide post and an output shaft of a wiper drive motor, whereby rotation of the output shaft aptly acts on the pivot arm to advance lateral movement of the wiper arm along the guide rail with that of the wiper blade assembly to effect entire surface cleaning of the window.

A windshield wiper system (3, 3′) for wiping a windshield (2) of a vehicle (1) includes a wiper (4) mounted on a movable support element, a guiding device for guiding the support element along a predefined trajectory and a motor mounted on the support element and arranged for providing traction power to move the support element along the predefined trajectory. The wiper system is arranged to move the wiper (4), relative to the windshield, with a translation movement between first and second positions, and with a rotation movement around a rotation axis perpendicular to the windshield between the second position and a third position.

A windshield wiper system includes a windshield wiper having a wiper blade with a near end and a far end. The windshield wiper is configured for performing a relative rotation of the wiper blade between the far end and the near end of the wiper blade. A mechanism applying a torque to the far end during a sweeping motion of the windshield wiper twists the far end of the wiper blade relative to the near end. The mechanism may perform the relative rotation of the wiper blade regardless of whether the wiper blade is in contact with a windshield. For example, the mechanism may include a stationary cam block having a cam profile, and an actuator arm moving along the cam profile with the sweeping motion of the windshield wiper. The cam profile is suitably shaped to pivot the actuator arm in laterally outer ranges of the sweeping motion.

Wiper arm (1) with pantograph dynamic action, comprising a main rod (2a) and a secondary rod (2b), characterized in that of the said main rod (2a) and secondary rod (2b) each comprises a negative lift surface profile the cross section of which is delimited by an upper side (25a, 25b), a lower side (26a, 26b), and, in the direction of the air flow, an anterior edge (23a, 23b) referred to as the leading edge and a posterior edge (24a, 24b) referred to as the trailing edge opposite the leading edge (23a, 23b),
and in that, in the position as mounted on a vehicle, the arm (1) is positioned with respect to the vehicle surface that is to be wiped in such a way that the said lower sides (26a, 26b) of the cross sections of the rods (2a, 2b) face towards the surface that is to be wiped, so as to press the arm (1) more firmly against the surface that is to be wiped.

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.

The present disclosure relates to a wiper system (100) for a vehicle windshield (102), the wiper system comprising a first wiper arm (104) and a second wiper arm (106), the first and second wiper arms being movable in at least a vertical direction (200); and a horizontal wiper arrangement (300) comprising a wiper blade (302) arranged to wipe the surface of the vehicle windshield, the horizontal wiper arrangement (300) further comprising a horizontally extending wiper guide element (304) connected to the wiper blade for arranging the wiper blade to extend between vertical end sides (502, 504) of the vehicle windshield, the first (104) and second (106) wiper arms being connected to the horizontally extending wiper guide element (304) for vertically moving the horizontal wiper arrangement (300) between a vertically lower position (602) of the vehicle windshield and a vertically higher position (604) of the vehicle windshield; wherein the wiper system (100) further comprises a plurality of spring elements (700) connecting the wiper blade (302) to the horizontally extending wiper guide element (304), the plurality of spring elements being spaced apart from each other along the length of the horizontally extending wiper guide element (304), wherein the spring elements (700) are arranged to force the wiper blade (302) towards the windshield in a horizontal direction (202) perpendicular to the direction of the horizontally extending wiper guide element.
