Disclosed is an aircraft windshield wiper system, having: a wiper arm; a reversible motor that drives the wiper arm, the motor including: a stator; a rotor configured to rotate relative to the stator; a forward shaft segment that is driven by the rotor and being rotationally connected to the wiper arm; an aft shaft segment that is driven by the rotor, the aft shaft segment including a forward end and an aft end; a ball nut that translates along the aft shaft segment from rotation of the aft shaft segment; a forward stop at a forward end of the aft shaft segment, configured to stop forward translational motion of the ball nut along the aft shaft segment; and an aft stop at an aft end of the aft shaft segment, configured to stop aft translational motion of the ball nut along the aft shaft segment.

The accessory for a windshield wiper is for use with a vehicle. The vehicle further includes a windshield and windshield wiper. The windshield wiper further includes a claw and one or more blades. The accessory for a windshield wiper attaches to the windshield wiper. The accessory for a windshield wiper comprises a lifting structure and a control apparatus. The control apparatus controls the operation of the lifting structure. The lifting structure is a mechanical device that physically raises or lowers the windshield wiper above the windshield or onto the windshield. The control apparatus controls the operation of the lifting structure.

A reciprocating wiper system according to the present invention may include a guide rail; a carrier unit coupled to be slidable in the guide rail and installed to reciprocate in a longitudinal direction of the guide rail; a cam member installed to be rotatable on the carrier unit; a wiper arm coupled to the cam member to move integrally with the cam member and to which a blade is coupled; a first pressing member for aligning the wiper arm in a direction perpendicular to the guide rail by rotating the cam member while the carrier unit is moving in a forward direction along the guide rail; and a second pressing member for aligning the wiper arm in a direction parallel to the guide rail by rotating the cam member while the carrier unit is moving in a reverse direction along the guide rail.

A wiper device that includes: a first control section that, during intermittent operation, controls power supply to a drive source such that a wiper blade wipes to-and-fro between a first return position and a second return position on a windshield and stops moving for a predetermined duration at the first return position, and that performs position retention control that controls power supply to the drive source such that the stopped wiper blade is retained at a position at which the wiper blade is stopped; and a second control section that suspends the position retention control by the first control section in a case in which a current flowing in the drive source is detected to have increased by a predetermined value or greater while the wiper blade moves toward the first return position within a predetermined region in a vicinity of the first return position.

The present invention relates to a movement transmission device (1′) for a vehicle wiper device (17) comprising a pivot shaft housing (3′) receiving a pivot shaft (5), a crank (7′) having a first end (8b′) and a second end (9b′). The first end of the crank is fixed to the pivot shaft and the second end of the crank is able to be linked to a link rod (11) transmitting a movement to the crank. The pivot shaft housing comprises limiting means (14) for limiting the movement of the crank.

Provided is a compact and high-strength cab capable of securing an excellent field of view for work. The cab includes a guard protecting a cab body, and a wiper having a blade to wipe a front window member and a blade actuator for actuating the blade. The guard includes a pair of side pillars and an actuator housing beam interconnecting the side pillars and housing the blade actuator. The actuator housing beam includes a hollow beam body formed with a body opening and a front-rear partition plate partitioning the inside of the beam body into front and rear sections. The body opening allows the blade actuator to be assembled to the front-rear partition plate therethrough.
