A wiper system includes at least one wiper assembly, a linkage assembly connected to the at least one wiper assembly, and at least one worm-driven reduction gear motor having a housing, an output shaft rotatably supported by the housing, and a motor arm connected to the output shaft and the linkage assembly to drive the at least one wiper assembly in repeated wiping motion across a surface to be wiped. The wiper system also includes a resilient interface assembly disposed between the housing and the motor arm to provide resistance to loading deflection and damp axial and cross-axial movement of the output shaft of the motor.

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.

A windshield wiper assembly for a dual sweep angle and indexable wiper system is provided. The system includes a wiper motor and a wiper arm for sweeping a surface of a windshield coupled to a first eccentric, the first eccentric comprising a primary eccentric and an indexable eccentric plate, wherein the indexable eccentric plate determines an eccentric offset of the wiper arm coupled to the first eccentric. The system further includes an output wiper shaft coupled to the wiper arm, a second eccentric coupled to a cam shaft, and a link coupled to the first eccentric and the second eccentric, the link having a first effective link arm length between the first eccentric and the second eccentric for driving the first eccentric to operate the wiper arm when operated in a first direction.

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.

Disclosed is a vehicle wiper control device which includes: wiper blades that can be disposed on a surface to be wiped and that perform a reciprocating wiping motion between a lower reversal position and an upper reversal position which are set on the surface to be wiped; an electric motor that reciprocates the wiper blades on the surface to be wiped; a drive portion that drives the electric motor; and a load calculation portion that calculates a load on the electric motor while the wiper blades wipe from the upper reversal position to the lower reversal position. If the calculated load value exceeds a predetermined threshold, the drive portion performs wiper stop processing for stopping the wiper blades at the lower reversal position or at a storage position which is set below the lower reversal position.

A vehicular camera module includes a housing, a camera disposed in the housing, and a transparent cover mounted at the housing. The camera views through the transparent cover. A wiper element is movable relative to the transparent cover to clean the transparent cover. The wiper element is moved via operation of a hydraulic actuator. With the vehicular camera module mounted at an exterior portion of a vehicle, the camera views through the transparent cover in order to capture image data of a scene exterior of the vehicle. With the vehicular camera module mounted at the exterior portion of the vehicle, the hydraulic actuator operates via pressurized fluid supplied to hydraulic actuator to move the wiper element back and forth across the transparent cover to clean the transparent cover of the vehicular camera module.

An interior windshield wiper apparatus for cleaning the interior of an automobile windshield includes a housing with a pair of wiper apertures extending therethrough. An engagement member is coupled to the housing to selectively engage a dashboard of a vehicle adjacent a windshield. An electric motor is coupled within the housing. A gearbox and a wiper linkage are coupled to the electric motor to drive a pair of wiper arms. The wiper arms are pivotably coupled to the housing and extends through the pair of wiper apertures. A pair of wiper blades is coupled to the pair of wiper arms to clean the windshield of the vehicle as the pair of wiper arms pivots. A wiper button is coupled to the housing to activate the movement of the pair of wiper arms.

The invention relates to an assembly comprising a crankpin which includes a ball joint, and a connecting rod which carries a ball joint housing, wherein the ball joint housing and the connecting rod are assembled by a bayonet mounting, and wherein the connecting rod comprises a locking hole through which an axial section of the ball joint housing passes, the connecting rod comprises at least one locking lug, the ball joint housing comprises a locking notch which is defined by two opposing radial faces, characterized in that one of the two opposing radial faces of the locking notch and one facing face of the locking lug each have a complementary inclined profile in order, during the rotation, to cause an axial clamping of the locking lug in-side the locking notch.
