A blade attachment tool includes a first support member supported by a pressing support portion supporting a blade formed of an elastic member configured to wipe/scrape liquid/solids spreading on an abutment surface by being pressed against the abutment surface and being long in one direction such that the blade is pressed against the abutment surface with a predetermined pressing force, a second support member supported to swing about a swing shaft extending in a longitudinal direction of the blade with respect to the first support member and configured such that a base end side of the blade is attached thereto, and an energizing member configured to apply a reaction force to a friction force that causes the second support member to swing about the swing shaft with respect to the first support member when the blade is pressed against the abutment surface to slide relatively to the abutment surface.

A multifunction windshield wiper includes a wiper arm, a wiper blade holder, and a wiper blade to facilitate, through channels, the direct distribution of the liquid or an air on the windshield surface. The direct distribution of the liquid and an air maximize the wiping effect and minimizes their usage. The wiper arm is assembled with wiper blade holder within the flexible spherical joints to refine the contact with a curved surface during the operational movement of the windshield wiper in the different weather conditions. The windshield wiper arm has a flexible joint with the link arm to facilitate the tension on the windshield surface during the wiping process.

A variable curvature wiper comprises a wiper arm with a first and second distal ends. The first distal end is pivotally supported on a pivot post. A flexible wiper blade has a first end, a second end and a mounting hub. The mounting hub is pivotally attached to the second distal end of the wiper arm. A first push rod includes a first end attached to the first end of the wiper blade and a second end attached to a push rod pivot point. The push rod pivot point is spaced from the pivot post axis. Pivotal motion of the wiper arm about the pivot post axis in a first direction causes the first push rod to push against the first end and flex the wiper blade. Pivotal motion of the wiper arm about the pivot post axis in a second direction causes the first push rod to pull the first end of the wiper blade back toward a flat position.

Windscreen wiper device for windscreens with variable curvature, comprising a secondary shaft rotating about its secondary axis between starting and final secondary positions, and a primary shaft on which the wiper blade arm is mounted rotating in an alternating manner about its own primary axis between starting and final primary positions. The primary shaft is mounted in the secondary shaft, such that their corresponding axes form a first acute angle () with respect to one another. The device further comprises a delay device kinematically connecting the driving means with the secondary shaft to cause rotation in the secondary shaft such that when the primary shaft has performed 50% of the rotation between the starting primary position and the final primary position, the secondary shaft has performed between 0% and 30% of the rotation between the starting secondary position and said final secondary position.

Drive mechanism configured for moving a wiper arm, the drive mechanism comprising a support assembly configured to cooperate with a wiper shaft extending according to a primary axis to allow a rotation of the wiper shaft with respect the support assembly according to the primary axis; a rotating assembly configured to be mounted in a rotationally fixed manner with the wiper shaft, the rotating assembly including at least one cylindrical bearing extending according to a secondary axis, the secondary axis being transverse to the primary axis; an inclination adjustment assembly including an inclination shaft configured to be fixed to the wiper arm and to cooperate with the at least one cylindrical bearing so as to be allowed to rotate according to the secondary axis, the inclination adjustment assembly further including a radial pin mounted on the inclination shaft and configured to cooperate with a biasing element of the support assembly.

A blade attachment tool includes a first support member supported by a pressing support portion supporting a blade formed of an elastic member configured to wipe/scrape liquid/solids spreading on an abutment surface by being pressed against the abutment surface and being long in one direction such that the blade is pressed against the abutment surface with a predetermined pressing force, a second support member supported to swing about a swing shaft extending in a longitudinal direction of the blade with respect to the first support member and configured such that a base end side of the blade is attached thereto, and an energizing member configured to apply a reaction force to a friction force that causes the second support member to swing about the swing shaft with respect to the first support member when the blade is pressed against the abutment surface to slide relatively to the abutment surface.

Wiper blade mounting assemblies are disclosed. In embodiments, the wiper blade mounting assemblies include an arm subassembly configured for attachment to a wiper blade mounting arm, and a wiper blade sub-assembly configured to attach to a wiper blade. The arm and wiper blade sub-assemblies may be configured to couple across a swivel coupling that is configured to permit a pre-determined degree of swivelling of the wiper blade sub-assembly relative to the arm sub-assembly. Methods of mounting wiper blade mounting assemblies and chatter free wipers including such wiper blade mounting assemblies are also disclosed.

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.
