A vehicle wiper device is provided including a first motor that swings a wiper arm such that a wiper blade coupled to a leading end portion of the wiper arm wipes a windshield, a second motor that extends or retracts an extension and retraction mechanism provided to the wiper arm in order to change a wiping range of the wiper blade, and a controller that controls rotation of the first motor such that the first motor rotates at a rotation speed corresponding to a wiping speed, and that controls rotation of the second motor so as to extend or retract the extension and retraction mechanism by an extension or retraction amount corresponding to the wiping speed during a wiping operation.

A washer tank according to an embodiment includes: a first container which stores a washer fluid and retains a temperature of the washer fluid; an inflow pipe through which the washer fluid flows into a storage space in the first container; an outflow pipe through which the washer fluid flows out of the first container from the storage space; and a heating portion which heats the washer fluid, in which all the inflow pipe, the outflow pipe, and the heating portion are disposed in a lower portion of the first container.

A wiper control device that properly detects restriction of a wiper blade according to a travel distance of the wiper blade. When a state in which a rotation speed of an output shaft calculated from a rotation angle of the output shaft detected by a rotation angle sensor is equal to or slower than a speed threshold defined according to a travel distance of the wiper blade and in which a current detected by a current detector is equal to or larger than a current threshold continues for a predetermined determination period, a microcomputer stops a wiper motor or reverses a direction of a wiping action of the wiper blade.

The versatility of a water collecting member is raised while improving the ease of assembly of the water collecting member. A water collecting member 80 is formed with plural first marks 90 serving as markers for assembly of the water collecting member 80 to a first pivot holder 20. The first pivot holder 20 is formed with a second mark 92 serving as a guide for the correct assembly orientation of the water collecting member 80 to the first pivot holder 20. The second mark 92 is formed corresponding to one out of the plural first marks 90, and is configured so as to form a pair with that first mark 90. The water collecting member 80 can be assembled in the correct position by aligning the second mark 92 and the first mark 90 that form a pair when assembling the water collecting member 80 to the first pivot holder 20. This thereby enables incorrect assembly of the water collecting member 80 to be prevented when assembling the water collecting member 80 to the first pivot holder 20 in cases in which a universal water collecting member 80 is employed in various vehicle models.

A windshield wiper system for an aircraft is provided and includes a motor, an output shaft, a wrap spring and crank rocker mechanism (WSCRM) to which the motor and the output shaft are coupled and a controller. By way of the WSCRM, first directional rotation input to the WSCRM from the motor via a two-stage gear reduction is converted such that the output shaft drives wiper blade oscillation through a first sweep angle and second directional rotation input to the WSCRM from the motor is converted such that the output shaft drives wiper blade oscillation through a second sweep angle. The controller is configured to control the motor such that the first directional rotation is continuously or non-continuously input during first or second flight conditions, respectively, and the second directional rotation is continuously input during third flight conditions.

A wiper device includes a pivot shaft, a pivot holder, a water receiving cap and a washer. The pivot holder includes a pivot support portion and a mounting leg. The pivot support portion pivotally supports the pivot shaft. The water receiving cap includes a boss portion and an umbrella portion. The boss portion is fitted onto the pivot support portion. The washer is fixed to a circumference of the pivot shaft at a portion projecting from a distal end of the pivot support portion. At least part of the boss portion overlaps the washer in an axial direction. The umbrella portion includes a projection that projects in the axial direction. The projection opposes the mounting leg in a circumferential direction without engaging the mounting leg in the axial direction.

An automobile vehicle wiper arm system includes a wiper arm base rotatably connected to a fixed structural member. A wiper arm extension is slidably disposed to the wiper arm base during wiper arm base travel about an arc of travel. A motion link is rotatably connected to the wiper arm extension and is rotatably connected to the fixed structural member. The motion link induces the wiper arm extension to outwardly displace and inwardly displace opposite to the outward displacement during wiper arm base rotation about the arc of travel. A wiper blade is connected to the wiper arm extension and traverses an oval-shaped travel arc along a vehicle windshield by the slidable displacement of the wiper arm extension during wiper arm base rotation. A linkage group connects the wiper arm extension to a wiper motor with rotation of the wiper arm base induced by operation of the wiper motor.

The present invention consists in a subassembly (1) of a linkage (2) of a wiper mechanism comprising: a bearing (3), a crank (5) articulated on the bearing (3) having a first end (51) connected to the bearing (3) and a second end (53) including a ball joint (7), and a link (9) one end of which is connected by the ball joint (7) to the crank (5), characterized in that at least the crank (5) includes a first through-opening and in that the subassembly (1) comprises a locking element (11) intended to be positioned in the first through-opening and configured to block relative movement between the link (9) and the crank (5).
