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.

The disclosure provides for a wiper system for cleaning a surface of a sensor housing, such as a sensor housing positioned on top of a vehicle. The wiper system includes a plurality of windows spaced around a sensor housing, and a plurality of wipers positioned around the sensor housing, each of the wipers includes a wiper blade configured to clean a corresponding window of the plurality of windows. The wiper system further includes a drive system including a movable part coupled to a motor. The motor is configured to drive the drive system to simultaneously rotate the plurality of wipers around the sensor housing such that the plurality of wipers remove debris from the plurality of windows.

A wiper device for a small and curved surface such as a spherical surface of an optical element includes at least one elongate wiper element with two ends, two drive units to which the ends of the wiper element are attached so that the wiper element can be moved on the surface of the optical element using the two drive units, and at least one contacting means for bringing the wiper element into contact with a surface of the optical element, the contacting means shapes the wiper element around at least that part of the surface which is exposed to the environment due to an opening provided by the housing and is to be cleaned.

A surface wiper device which includes a carrier which supports a blade. The carrier attaches to a wiper arm which urges the blade against and moves the blade across the surface of a windshield. The carrier further provides a plurality of outlets each of which communicate between a hollow passage inside the carrier and a location on the external surface of the carrier. A fluid can be delivered from a fluid source fluidicly coupled to the hollow passage of the carrier under sufficient pressure to be dispersed from the plurality of outlets onto the windshield during movement of the blade. A fluid heater can be thermally coupled with the fluid delivered from the fluid source to the plurality of outlets to increase the temperature of the fluid dispersed onto the windshield. The fluid can be sufficiently heated to generate a heated gas.
