Preferably, the free inner end of the wiper blade and preferably also the second wiper nozzle unit in operation rotate on an inner path of the wiper device.
    Preferably, the inner path is at least a portion of the inner circle traveled by the wiper device. The inner circle has, in particular, a center which is in the center of rotation around which the windshield wiper arm and / or the operating windscreen wiper blade rotate. The second end of the wiper blade is in particular the free end or outer end of the wiper blade which is opposite to the free inner end of the wiper blade. In particular, the free outer end of the wiper blade travels a path which, preferably with the window of visibility inside the inner trajectory, corresponds in particular to the main window of visibility of the occupant of the vehicle. , especially the driver.
    In the present description, a wiping nozzle unit is in particular a unit for applying liquid and in particular washing water to clean the glass; this unit comprises at least one wiper nozzle element. In this context, a wiper nozzle element is in particular an element for applying a liquid and in particular a wiper liquid on the window, in particular on the window of the vehicle to clean it by projecting the liquid in a direction of projection. defined; this element comprises at least one outlet orifice. Preferably, the wiping nozzle element is connected by a water pipe of the wiper device to the water pump and / or a valve of the wiper device. The washing water is, in the present description, the liquid used to wipe, wash and / or clean a window of the vehicle. This is for example water, alcohol or mixtures which comprise a water fraction, antifreeze agent fraction and / or an alcohol fraction. The operating state according to the present description corresponds to an operating mode and / or an operating state in which the windscreen wiper blade is moved parallel to the window of the vehicle. In particular, the wiper device operates at least in a first operating state and in a second operating state with opposite wiping directions. The wiping direction according to the present description is the direction in which the wiper blade is led on the window wiper of the vehicle in a certain operation. In particular, the wiping direction is at least substantially perpendicular to the longitudinal direction of the wiper blade and preferably it is at least substantially perpendicular to the surface of the vehicle window. In particular, there are two wiping directions which are essentially oriented in the opposite direction to one another. The expression "at least essentially opposed" means in the present context that the two directions make an angle of 180 ° between them and in particular with up to a maximum deviation of 15 ° and preferably a maximum of 10 ° and in a particularly preferred manner equal to 5 °. The two normal faces of the two opposite side surfaces represent a geometric square that completely surrounds the wiper arm and / or the wiper blade and corresponds to the two wiping directions. The longitudinal direction according to the present description designates the direction parallel to the longest edge of the smallest square imagined and which still completely surrounds the object.
    Thanks to such an embodiment, the wiper device gives better wiping results and in particular the negative influence of the main window of visibility of the driver with the washing water is avoided.
    In particular, the second wiper nozzle unit is closer to the free inner end of the wiper blade than the first wiper nozzle unit. Advantageously, the second wiper nozzle unit is in the vicinity of the free inner end of the wiper blade. In particular, the second wiper nozzle unit is installed on the wiper arm so that in the rest position of the wiper device, this unit is at least essentially hidden when look from inside the vehicle. The second wiper nozzle unit is in particular at least a portion, preferably substantially and particularly preferably, wholly located on the outer side of the wiper arm. The second wiper nozzle unit is advantageously positioned at least in part and preferably at least in large part and in a particularly preferential manner the entire wiper device in the rest position is placed in particular in the limit range of vision. The limit of vision range according to the present description thus means a range of a window of the vehicle which is hidden from view for the occupant of the vehicle, in particular for the driver of the vehicle from the inside of the vehicle and which corresponds to the visibility limit range. In particular, the range limiting the visibility is covered from within the vehicle at least partially, at least completely and in a particularly preferential manner, completely from the vehicle interior console. This allows the wiper nozzle unit to be positioned in the edge area of the main view window of a vehicle user. In particular, particularly in the idle state of the wiper arm, the assembly of the second wiper nozzle unit is within a visibility limit area so that it, -ci view from the inside of the vehicle, remains hidden for the occupants of the vehicle and in particular for the driver.

The different sides are in particular the sides of a plane parallel to the longitudinal direction. Preferably, the plane is perpendicular to the vehicle window. In particular, the two sides considered in the longitudinal direction of the object are the opposite sides and preferably left and / or right sides in the longitudinal direction.
    In particular, the different sides are oriented towards the different directions of wiping. This improves the effect of cleaning.
    It is further proposed that the second wiper unit applies washing water in at least one operating condition, only to the upper area of the vehicle window by sweeping in its operating state, at least partially, the wiper arm segment especially in the area near the free inner end of the wiper blade. To reduce the size of the main window of visibility of the occupant of the vehicle, including the driver by washing water.
    According to another feature, the first wash nozzle unit projects water in at least a first direction and the second wash unit 16 projects washing water in at least a second direction substantially different from the first direction.
    Preferably, the first direction is at least substantially parallel to the longitudinal direction of the windscreen wiper blade and / or the wiper arm and in particular at least substantially parallel to the window of the motor vehicle. As the two "substantially different" directions, this means that two straight lines which intersect each other and which are each parallel to one of the two directions, form between them at least an angle of at least 5 ° and preferably of at least 5 °. at least 15 ° and particularly preferably at least 25 °. The second direction is in particular substantially perpendicular to the longitudinal direction of the wiper arm and / or the wiper blade, in particular a window of the vehicle. Most of the window of the vehicle will be wet with the wash water and at the same time only very slightly limits the window of vision and / or visibility of an occupant, in particular the driver of the vehicle.
    According to another characteristic, the first washing nozzle unit and the second washing nozzle unit, at least in an operating state, in particular in the first and / or the second operating state and in a particularly preferred manner, in the first operating state simultaneously applies wash water to the vehicle window at least once in a while.

The control of the distribution of the washing water can be done in particular by modifying the position of the valve, by adapting the pressure of the washing water, in particular by means of the washing water pump and / or a variation of the outlet port of the wiper nozzle member. The valve 60a is in particular an electrical switching control valve. The valve is connected in particular directly or indirectly by a washing water pipe to at least one of the wiping nozzle units and preferably the first wiping nozzle unit and / or the second wiper nozzle unit. wiping. In addition and / or alternatively, the valve is a low pressure valve. The valve comprises at least two connections, preferably at least three connections and in a particularly preferred manner, at least two switching positions and preferably at least three switching positions. It is advantageous that the valve is provided on the wiper arm and in a particularly advantageous manner, it is under the wiper arm adapter in the front segment and / or below the segment. inferior.

The actuator is in particular the control motor and, in a particularly preferred manner, a piezoelectric actuator and, in a particularly preferred manner, a control of the windscreen wiper motor and / or a wash water pump. This leads to an advantageous and fast control of the wiper nozzle unit. Advantageously, the valve is positioned near the wiper nozzle element, which improves the reaction time. According to another advantageous characteristic, any additional non-return valve in the wiping nozzle units and / or a washing water pipe is avoided.
    According to a development of the invention, the control unit in at least one operating state, in particular in its first operating state, controls at least from time to time simultaneously the first wiper nozzle unit which improves the duration action of the wiping water.
    According to a preferred development, in at least one operating state, the control unit provides control of either the first wiper nozzle unit or the second wiper nozzle unit. In particular, the control unit separately controls the first wiping nozzle unit and the second wiping nozzle unit in different operating states from each other. The control unit is preferably provided for controlling the first wiper nozzle unit in a first operating state and in particular not controlling the second wiper nozzle unit. According to another advantageous characteristic, the control unit does not control the first wiping nozzle unit in a second operating state while in this second operating state it controls the second wiping nozzle unit.
