A vehicular wiper device includes a first wiper arm, a first drive source, a rocking mechanism, a second drive source, an extension and retraction mechanism, and a control unit. A first wiper blade for wiping a surface to be wiped of a vehicle is connected to the front end of the first wiper arm. The first drive source is directly or indirectly affixed to the vehicle body. The rocking mechanism is driven by the drive force of the first drive source and reciprocates and rocks the first wiper arm. The second drive source is directly or indirectly affixed to the vehicle body separately from the first drive source. The extension and retraction mechanism is driven by the drive force of the second drive source and extends and retracts the first wiper arm in the longitudinal direction thereof. The control unit controls the drive of the first drive source and the second drive source so that the extension and retraction operation of the first wiper arm performed by the extension and retraction mechanism will correspond to the rocking operation of the first wiper arm performed by the rocking mechanism.

According to the present disclosure there is provided a wiper assembly for removing contaminants from a surface of a housing provided around a sensor, comprising: a drive system; a moveable part connected to the drive system to be driven by the drive system; and at least one wiper connected to the moveable part, wherein the drive system is configured to drive the moveable part, thereby to cause movement of the at least one wiper at least partially around the housing thereby to wipe the surface of the housing to remove contaminants therefrom. Further, according to the present disclosure there is provided: a sensor assembly comprising a sensor and a wiper assembly; a vehicle; and a method of operating a wiper assembly.

A wiper arm for supporting a wiper blade includes a wiper arm head comprises a recessed splined cup portion having a plurality of angularly adjacent teeth about the internal circumference of the cup portion wherein the cup portion includes a slot. A complementary drive shaft includes a splined head having teeth for mating engagement with the teeth in the wiper arm head. In order to facilitate the alignment therebetween, an integral alignment key is received in the axially aligned slots. The alignment key further includes a lower notched end which abuts against a bottom radial lip of the splined head to prevent the key from moving axially in the slots. As such, the key and the splined head include complementary formations preventing the key from accidentally falling out of the slots.

In the case of a windshield wiper system with two opposite wipers 1, 2, 4, 5 and two reversing motors 6, 7, the risk of a collision of the wipers can be diminished greatly in that a defined phase displacement is generated between the wiping movements of the two wipers, which are driven in a reversing manner, with the aid of the lever mechanism 8 associated with the reversing motors, and said phase displacement is arranged so that the one wiper is leading relative to the other wiper in the first wiping direction and lagging in the second wiping direction.

An emergency windshield wiper system that attaches to the windshield of a vehicle. The system comprises of a platform that is used to secure a battery, a motor, a control, a pair of suction cups, an oscillating gear and an arm that holds a windshield wiper. The suction cups are positioned at opposite ends of the platform so that a center of gravity is created at a midpoint of the platform. The oscillating gear is positioned at the midpoint of the platform and it connects via a connector gear rod to a motor gear that is attached to the motor. The battery, motor and the control are operatively connected. The oscillating gear attaches to the arm. The windshield wiper inserts within the arm of the windshield wiper system.
