[0001] Field of the Invention The present invention relates to a vehicle wiper device, particularly a motor vehicle. The invention relates in particular to a windscreen wiper of a motor vehicle rear window. State of the art Typically, wiper devices have a wiper arm or lever carrying a wiper blade for cleaning a vehicle window. The wiper blade is movable between a first and a second movement reversing position and for this the arm is connected by a drive shaft to a wiper motor. In particular, in the case of windshields with a large variation of curvature, the wiper blade easily loses contact with the windshield, so that in the case of strongly curved windshield wiping will be or leave unclean areas or trails. As for wiping, it is necessary to optimize a large number of parameters, such as, for example, the amount of rain arriving on the window or the windshield, the possible snow load on the windshield, the speed of the vehicle. and so the wind pressure on the wiper arm, we can not simply adjust the pressure of the wiper arm exerted on the windshield to avoid with certainty the development of a sail or of streaks. There is not only a concern for improving the wiper devices, but also a requirement for comfort, and improving the safety of the vehicle. For this purpose, for example, cameras are used, such as cameras for assisting parking maneuvers in a parking space. OBJECT OF THE INVENTION The object of the present invention is to develop windscreen wiper devices to improve wiping and to permit reliable, virtually drag-free wiping of a vehicle window while also providing assistance. SUMMARY OF THE INVENTION AND ADVANTAGES OF THE INVENTION To this end, the subject of the invention is a wiper device of the type defined above, having an elongated upper part at least partially flexible, an elongated at least partially flexible bottom part, a plurality of connecting elements connecting the upper part and the lower part, these connecting elements being distributed in the direction of longitudinal extension of the wiper blade and allowing the relative movement of the upper and lower portions relative to one another with a movement component in the direction of longitudinal extension of the wiper blade ace, as well as a module including a camera. In other words, the subject of the invention is a vehicle wiper device, in particular a motor vehicle. The wiper device comprises a wiper blade with an elongated upper portion and an elongated lower portion, these portions being at least partially flexible. Several connecting elements connect the upper part and the lower part. These connecting elements are distributed in the direction of longitudinal extension of the wiper blade. The connecting elements allow the relative movement of the upper part and the lower part relative to each other with a component of movements in the direction of longitudinal extension of the wiper blade. The wiper device comprises a module with a camera such as, for example, a camera assisting storage maneuvers.
[0002] According to another development, the subject of the invention is a method for managing a wiper device comprising receiving video data from a camera integrated in the wiper device and representing the video data on the wiper device. a display unit of a reception unit, the latter being chosen from the group consisting of the following components: navigation system, tablet computer, smartphone, on-board computer; the method includes positioning the wiper device in a position of the stationary wiper blade, different from the storage position, in particular a camera position further corresponding essentially to the region of the wiper blade; median of the windshield or the window of the motor vehicle and / or the vertical position of the wiper blade. The embodiments of the wiper devices according to the invention for vehicles can be made in a particularly advantageous manner and for a multiplicity of different application areas. A windscreen wiper device such as for example a Fin-Ray wiper comprises a camera, such as a camera assisting storage maneuvers. Thus, with the aid of a replacement wiper, it is possible to retrofit a vehicle in a simple manner with a camera assisting storage maneuvers. The wiper device can be equipped with more than one camera, for example two or three cameras to not only use the camera as an aid to storage maneuvers, but also in other situations of road traffic . This improves safety or reduces the risk of accidents. According to a development, the invention relates to a vehicle windscreen wiper device, especially a motor vehicle. The wiper device comprises a wiper blade having an elongated upper portion and an elongated lower portion that are both at least partially flexible. Several connecting elements connect the upper part to the lower part; the connecting elements are distributed along the longitudinal extension of the wiper blade. The connecting members are adapted to allow relative movement of the upper portion and the lower portion relative to one another with a movement component in the longitudinal direction of extension of the wiper blade. The windscreen wiper device further comprises a camera module equipped with a camera, for example a camera for assistance with storage maneuvers. Thus, beside a good wiping result, safety is improved for driving the vehicle by better peripheral visibility. In particular, the integration of a camera in a rear window wiper gives a better overview of the traffic situation in the case of a storage maneuver or a reverse maneuver .
[0003] According to one characteristic, the wiper device comprises a connecting piece connecting the upper part and the lower part; the camera is housed on the link unit or is provided thereto in that, in particular, the connecting piece is a connecting piece on the wiper blade side which makes a removable connection with the element linkage on the vehicle side. For example, an actuator is adapted to release a force and / or shape connection between the fastener and the fastener. The quick-lock connection makes it easy to retrofit a wiper blade with an integrated camera. In addition, the connecting piece is suitable for the integration of the camera. According to one development, the camera module includes a transmitter for transmitting video information over a wireless link. A video transmission of image information is particularly suitable for the installation of a camera in retrofit. In addition, it allows to communicate with current mobile devices, such as a navigation system, a tablet, a smartphone and / or similar devices. According to a characteristic development, the camera module comprises a power supply unit with at least one of the elements of the group comprising: accumulator, photovoltaic cell, generator. In particular, the first autarkic camera unit comprises an accumulator equipped with a lens for automatic charging, for example by a generator or a photovoltaic cell. According to a characteristic development, the connecting piece positions the camera in a first position corresponding to the left side storage position and / or a second position corresponding to the right side storage position, which makes it possible to direct the camera on the pavement according to the storage position of the wiper blade. According to a characteristic development, the connecting piece positions the camera in a third position between the first and the second position and this third position is adjusted, in particular in a variable manner. Thus, in addition to the camera assisting storage maneuvers, one can also have a rear view camera with a side view. According to the typical embodiments that can be combined with other embodiments, a second camera or even another camera can also be integrated in the windshield wiper device. According to a development, the camera module comprises an optical and a housing, in particular in the form of a ball joint connected to a ball joint or using a ball joint. Optics have an appropriate range for the field of view.
[0004] The ball joint offers a simple possibility to adjust the field of view. According to another development, the wiper device comprises a control adapted for another stationary position of the wiper blade, different from the storage position, in particular a camera position which corresponds to the essential, at the middle region of the window of the motor vehicle and / or at a vertical position of the wiper blade. We will have a reverse assistant, for example for garage exits or courses. According to one development, at the end opposite the binding position, the wiper blade has a width of 20 mm or more, especially 30 mm or more. This characteristic form of a Fin-Ray wiper blade makes it possible to integrate the camera and can be optionally equipped in a particularly simple way with a photovoltaic cell.
[0005] According to a characteristic development, the element integrating the camera of the windscreen wiper device is asymmetrical with respect to the mirror image of an axis parallel to the longitudinal extension of the wiper device and in particular the embodiment asymmetrical allows a shift of the position of the camera relative to the axis of rotation of the wiper device. The connecting piece may, for example be of asymmetric shape with respect to the mirror plane of an axis parallel to the longitudinal extension of the wiper device. This asymmetrical shape improves the position of the camera to allow it, for example, to better look at a troublesome ridge at the rear of the vehicle.
[0006] The connecting elements according to the invention are configured so that the distance between the upper part and the lower part varies at least partially, especially continuously along the longitudinal extension of the wiper blade. The distance between the upper part and the lower part in the direction of longitudinal extension of the wiper blade may decrease in a first zone of the wiper blade and increase in a second zone thereof. In addition, the wiper blade may include an area in which the distance between the upper and lower portions is substantially constant in the direction of longitudinal extension of the wiper blade. The result is a windshield wiper device that better matches the curvature of the window / windshield. The connecting elements are configured so that the variable distance between the upper portion and the lower portion passes a minimum distance along the longitudinal extension of the wiper blade towards the end of the wiper blade. The minimum distance between the upper part and the lower part can be between the connection piece and the connection position between the upper part and the lower part according to the longitudinal extension of the wiper blade. The minimum distance between the upper part and the lower part is substantially in the middle in the direction of longitudinal extension of the wiper blade. In addition, the minimum distance between the upper part and the lower part is also in a region of the wiper blade which is shifted towards the end of the wiper blade. There is thus a wiper device for particularly good adaptation to the curvature of the window. The connecting elements are hingedly connected to the lower part and / or the upper part. In particular, the connecting elements are connected to the lower part and / or to the upper part by means of a first hinge film. The first film-hinge can be made in one piece with the connecting element and with the upper part and / or with the lower part. The one-piece production of the hinge film enables simple and economical manufacture. It is thus possible to have wiper blades or wiper devices of corresponding shape and which are directly available or usable at the outlet of the mold. In addition, the use of hinge films, in particular for the one-piece production of hinge films with connecting elements and the upper part and / or the lower part allows injection molding. The width of the lower part and / or that of the upper part in the direction of longitudinal extension of the wiper blade decreases towards the end of the wiper blade and this in particular continuously. There is thus a wiper blade device whose moment of inertia decreases towards its end. In addition, there will be a substantially uniform application pressure of the wiper device against the window and also a uniform distribution of the forces of the wiper blade device which gives a better adaptation to the window and is translated by a very good quality of wiping. The invention also relates to a wiper device management method of receiving the video data of a camera integrated in the windscreen wiper device and presenting them on a display, with a unit receiver selected from the group consisting of: a navigation system, a tablet computer, a smartphone and an on-board computer; the method further ensures the positioning of the wiper device in a stationary position of the wiper blade, different from the parking positions, including a camera position. The camera position is furthermore, in particular for the most part, in the middle part of the vehicle window and / or in a perpendicular position of the wiper blade.

DESCRIPTION OF EMBODIMENTS FIG. 1 shows in perspective a windscreen wiper blade 2 of a wiper device according to one embodiment of the invention. The windscreen wiper device is in particular a Fin-Ray wiper. The wiper blade has an elongated upper portion 10 and an elongate lower portion 12. The upper portion 10 and the lower portion 12 are at least partially flexible. The upper part 10 and the lower part 12 are connected by connecting elements 18. The connecting elements 18 are distributed in the direction of longitudinal extension of the wiper blade 2 and allow the relative movement of the upper part 10 and the lower portion 12 relative to each other, mainly in the direction of longitudinal extension. The wiper blade 2 has a wedge shape; the upper part 10 and the lower part 12 are connected to each other in the outer connection position 34. The upper part 10 and the lower part 12 are fixed to a fastener 30. The fastener 30 is a windscreen wiper blade attachment which can be attached to a vehicle fastener 50, for example a motor vehicle. Fixing between the fixing piece 30 and the fixing element 50 can be done for example with an actuating device 21, for example a push-button, a lever, or a snap-fastener or any other device. actuation which can thus be released. According to the embodiments described, the wiper blade 2 is removably connected by the fixing element 50 and the fastening piece 30. The fastening piece 30, on the wiper blade side, is takes the actuating device to release the connection by force and / or shape between the fastener 30 and the fastener 50. According to the characteristic embodiments, the actuating device 21 has a key or a push button. The user can thus actuate the actuating device 21 to release it by force and / or by the connection by the shape, to disassemble the windscreen wiper device or to remove it from the fastener 50. corresponding, the wiper device simply replaces or disassembles to then go up just before passing through a washing tunnel. The fixing element 50 forms the interface for the transmission of the torque with the wiper arm (reference 53) for the axial locking by a retaining spring (cavity 51) and / or for the axial guidance by the arm windscreen wiper (reference 54). A locking element, for example a fixing spring, is integrally integrated in the windscreen wiper blade or in the attachment part 30 on the wiper blade side, or it is integrated by injection. The wiper blade slides axially on the bearing shaft. According to characteristic embodiments, there is thus a translational movement for fixing. This translational movement is shown schematically by the arrow in FIG. 1. For example, when one engages on the axis, a spring departs and enters the cavity (interface) 51. The transmission of the torque is done by The interface 53. According to characteristic embodiments, the interface 54 has radial clearance or more simply a radial clearance. As appears in particular in the description of Figure 1, a windscreen wiper device, including a wiper Fin-Ray can simply mount and disassemble just as easily with a quick link. Thus, according to Figure 2, the wiper device equipped with a camera 200 is easily mounted on a vehicle. Typically, the link elements are integrated in a camera module. The camera can thus be a main unit with for example a power supply unit, a control, a signal transmission and / or other components. The camera 200 does not appear in the characteristic representation of FIG. 1 because it is located, for example, on the rear side of the fixing piece 30. A wiper device integrating a camera may for example to be used for the rear window. A wiper device incorporating a camera may for example replace an old broom. For example, a windscreen wiper device with a quick-release mechanism makes it possible to dismantle the rear wiper device by means of a rapid closing mechanism and dismounted from the vehicle drive shaft in order to be replaced by the new wiper device integrating the camera. According to one embodiment, an old, hectic user can disassemble the drive shaft, for example in a knurled cone, and screw a standard adapter on the shaft so that the wiper Fin-Ray mounts in the axial direction on the shaft, for example by a quick closure. Figure 2 shows a rear window 4 and a wiper blade 2 of a windscreen wiper device shown here, for example in the form of a rear window wiper. The wiper device integrates a camera 200 with a field of view 502 or camera angle. According to typical embodiments, the windscreen wiper device is a Fin-Ray wiper device. This windscreen wiper device has a width W of at least 20 mm. The Fin-Ray wiper device is wedge-shaped in side view and / or top view. According to the embodiments described and which can be combined with other embodiments, the Fin-Ray wiper device comprises a fastener 30 for mounting by a quick-closing connection. This form and / or the possibility of a fast closing connection results in a particularly advantageous integration of a camera into a wiper device. For example, a rear window wiper of the Fin-Ray type incorporates a camera assisting with storage maneuvers. According to embodiments that can be combined with other embodiments, the camera transmits its information over a WLAN, Bluetooth or ZigBee network to a display. According to other embodiments that can be combined, the display is for example the vehicle display which is the navigation system, a tablet computer or a smartphone. The embodiments of the present invention, however, do not allow cable video transmission. By way of example, a replacement wiper makes it possible to equip, simply with a second vehicle, a vehicle with an assistance camera for storage maneuvers (or rear view camera), particularly if the display is a parking system. commercial navigation, a computer tablet or a smartphone. In addition, the wiper blade of a rear window is located at the location of the vehicle that provides a wide angle of view for the camera. This is shown in Figure 2 by the viewing range 502. Figure 2 shows the camera 200 on one side of the wiper blade 2; the wiper blade is in the storage position on the left side of the window 4. Thus, the field of view 502 of the camera 200 is oriented downward and rearward. For a storage position, the camera 200 may be provided on the opposite side of the fastener 30. The camera wiper device may be retrofitted to the left or right for the camera position. parking. Typically, this depends on the storage position of the wiper device and the side by which the wiper device or the wiper is positioned relative to the camera. The camera is oriented in a characteristic manner towards the roadway. Figure 3 is a schematic view of a wiper blade 2 of a vehicle wiper device, including a motor vehicle; it is represented in the basic position, that is to say in the unsolicited state. Specific developments of a wiper blade Fin-Ray which give a good wiping result will be described in connection with Figures 3, 4A, 4B. Although such details, aspects and features are not necessarily related to the integration of a camera, these elements nevertheless contribute to an improvement of the windshield wiper device and / or have the property of permitting integration of a camera. The wiper blade is comprised of an elongate upper portion and an elongate lower portion 12, which are at least partially flexible. Several connecting elements 18 connect the upper part 10 and the lower part 12 being distributed in the direction of longitudinal extension 8 of the wiper blade 2. The connecting elements 18 make it possible to transmit the movement of the upper part 10 to the lower part 12 according to a component of movement in the direction of longitudinal extension 8 of the wiper blade 2. The connecting elements 18 are installed relative to the lower part 12 so that in the state not When applied to the wiper blade 2, they form an angle α between the respective longitudinal axis 24 of the connecting elements 18 and at the lower part 12, at least partly along the longitudinal extension 8 of the wiper blade 2. wiper blade 2 which can thus be modified, especially modified continuously or monotonously or in a strictly monotonous manner.
[0007] In the wiper blade in the unsolicited state, shown in FIG. 3, the angles α between the respective longitudinal axis of the connecting element 18 and the lower part 12 vary in the direction of longitudinal extension. 8 of the wiper blade 2; these angles bear the references al, a2, a3 ... an-1, an. According to the embodiments of the wiper blade which can be combined with other embodiments, the connecting elements 18 may in particular be attached to the lower part 12 in the unsolicited state of the wiper blade. ice 2. Thus, the longitudinal axis 24 of the connecting elements 18 is at an angle to the bottom portion 12; this angle an is between a lower limit angular value anu and an upper limit angular value ano. According to the embodiments, the angular sector is less than = 10 °, in particular anu = 15 °, in particular anu = 20 ° and the upper limit value of the angular sector is ano = 80 °, in particular ano = 90 ° and all especially ano = 100 °. This advantageously guarantees a particularly good transmission of the force acting on the lower part towards the upper part. In addition, and in this way, we have a wiper device particularly stable and to have a very even application pressure against the window, which allows a better adaptation of the wiper blade to the glass and excellent wiping quality. According to the embodiments of the wiper device which can be combined with other embodiments, the connecting elements 18 are configured so that the distance between the upper part 10 and the lower part 12, at least partially the along the longitudinal extension direction 8 of the wiper blade 2, decreases steadily in a first range and increases in a second constant range. According to the embodiments of the wiper blade which can be combined, the internal gap is at least 15 mm, in particular at least 25 mm and in particular at least 35 mm. According to the embodiments, the external deviation, that is to say the distance or the distance at the connecting position 34 is equal to at least 10 mm, in particular at least 12.5 mm and in particular at least 15 mm. According to a characteristic, the distance or average deviation is at least 7.5 mm, in particular at least 12.5 mm. According to the embodiment of FIG. 3, the connecting elements 18 are hingedly connected to the lower part 12 and / or to the upper part 10. The connecting elements 18 are connected in particular to the lower part 12 and / or at the top 10 by a first hinge film 20. The first hinge film 20 is in one piece with the connecting element 18 and with the upper part 10 and / or with the lower part 12. realization of the hinge film in one piece allows a simple and economical manufacture. Thus, the wiper blades or the wiper blade devices for corresponding embodiments can be manufactured so as to be used directly at the outlet of the mold. In addition, the use of hinge films, in particular the one-piece production of the hinge films with the connecting elements and the upper part and / or the lower part allows injection molding. According to one characteristic, the thickness of the upper part decreases according to the longitudinal extension of the wiper blade, in particular by a monotonous reduction and in particular a strictly monotonous reduction. Thus, there will be a wiper device which, at the end of the wiper blade, will have a decreasing moment of inertia, especially to the end of the wiper blade, by a monotonous decrease, especially strictly monotonous. The wiper device can thus adapt particularly well to the curvature of the window. According to the embodiment of Figure 1, the wiper blade is configured so that the width of the lower part and / or the width W in top view of the upper part, in the direction of longitudinal extension The wiper blade decreases towards the end of the wiper blade, in particular by a monotone reduction, in particular strictly monotonous. There is thus a wiper device which decreases towards the end of the wiper blade. According to developments of the wiper blade, the outer width of the wiper blade, in particular of the upper part and / or the lower part, will be at least 15 mm, in particular from minus 20 mm and in particular at least 25 mm. According to embodiments of the wiper blade which can be combined with other embodiments, the inner width (see W reference) of the wiper blade, in particular the upper part and / or the lower part is at least 20 mm, especially at least 25 mm and in particular at least 30 mm. The width of the wiper blade and the realization inter alia linked thereto of the connecting piece 30 allow a particularly good integration of a camera. Developments of the wiper device will be given hereinafter by way of example with the aid of FIGS. 4A and 4B corresponding to particularly advantageous embodiments of the windscreen wiper device, in particular variants of the wiper device. structure. This allows among other things to describe the principle of a wiper blade type Fin-Ray.
[0008] Figure 4A schematically shows another embodiment of the wiper device of the invention shown in the basic position. The wiper device consists of a wiper arm incorporating a wiper blade 2 installed on a fastener 30. The fastener 30 is connected to a windshield wiper motor 32 which drives the fastener 30 to wipe the window 4. The wiper blade 2 is wedge-shaped; one end of the upper part 10 is integrally connected to the outer connection position 34 at the end of the lower part 12. The other respective end of the upper part 10 and that of the lower part 12 are connected to the piece of 30. The wiper blade 2 can wipe a vehicle window 4 for example that of a motor vehicle. The wiper blade 2 has a longitudinal extension 8 with an elongated upper portion 10 and a lower portion 12 also elongated. The longitudinal extension of the upper part 10 and that of the lower part 12 correspond essentially to the longitudinal extension 8 of the windscreen wiper blade 2. Both the upper part 10 and the lower part 12 are flexible beams or are made in the form of flexible beams shown by way of example in one piece in Figures 4A and 4B. This allows a particularly solid construction. According to other embodiments, the upper part 10 and the lower part 12 use a material having a modulus of elasticity in a range, in particular between 0.005 kN / mm 2 and 0.5 kN / mm 2, in particular between 0 , 01 kN / mm 2 and 0.1 kN / mm 2. This makes it possible to have the appropriate flexibility for the upper part 10 and the lower part 12. Properly shaped section surfaces of the upper part 10 and the lower part 12 thus achieving optimum flexibility. The upper part 10 and the lower part 12 face each other.
[0009] The end of the upper part 10 is connected to the end of the lower part 12 by a connection secured to the outer connection position 34. The embodiments in which the hinge 20 is a hinge-film thus constitute an embodiment simple for wiper device joints or wiper blade type Fin-Ray. The wiper blade 2 may be in one piece, especially used directly at the outlet of the mold. According to typical embodiments, the hinge films have a very high extensibility. This results for example from the choice of material in the group PP, PE, POM, and PA. Alternatively, the hinge films may be made of one or more materials from the group comprising TPE (thermoplastic elastomer, for example TPE-S, TPE-O, TPE-U, TPEA, TPE-V and TPE-E). The connecting elements 18 are distributed in the direction of longitudinal extension of the wiper blade 2. The differences are advantageously less than 50 mm, especially less than 30 mm. FIG. 4B is a schematic representation of the wiper blade 2 of FIG. 4A in position applied against the window pane 4. As the window pane 4 has a certain curvature, when the wiper blade 2 is applied against the pane 4, contact pressure forces are exerted on the lower part 12. As the upper part 10 and the lower part 12 are flexible beams and the connecting elements 12 are rotatably mounted on the part upper and lower part 12, these two parts 10, 12 can slide relative to each other. Pushing forces acting from below on the lower part 12, deform the wiper blade 2 in the direction from which the thrust forces come and it applies precisely against the curvature of the window pane 4. realization of the examples described above that a force exerted on the lower part (by the window 4) develops the bending of the lower part in the direction coming from the force. This is ensured by the connection of the upper part 10 and the lower part 12 to a connecting position 34, by the shape and the rotational joints of the connection between the connecting elements and the upper part or the lower part. In the representation of Figure 4B there is a small gap between the wiper blade 2 and the window 4; this interval is provided here only to clarify the window 4 and the wiper blade 2; in fact, when the wiper blade 2 is applied against the window 4, this gap does not exist. Furthermore, and typically, the side of the lower portion 12 not facing the upper portion 10 has a wiping lip for wiping the windowpane 4. For the sake of clarity of the drawing, this lip has not been represented in FIGS. 4A and 4B. The wiper device according to the embodiments described above uses the effect of the tail scales of some fish which, under the effect of a lateral thrust, do not escape in the direction of the thrust, but bulge in the opposite direction, that is, in the direction from which the thrust originates. This principle, referred to as the "Fish Scale Principle" or "Fin-Ray Principle", means that the wiper device according to the embodiments described above is better suited to the vehicle window, unlike a broom. conventional wiper whose upper part is usually rigid, that is to say non-flexible. The fastener 30 shown in FIGS. 4A and 4B has on one side a camera 200. Typically, the camera has an optic 202 and a housing 204. The housing 204 serves to hold the camera 200, for example. also receive electrical or electronic components such as for example a radio transmitter for transmitting the video signals from the camera, a camera reading unit and / or a camera control unit.
[0010] FIG. 5A shows a vehicle 5 whose rear window 4 is equipped with a rear wiper with a camera 200. The vehicle 5 is for example in a parking maneuver reversing and thus approaching the vehicle 50. The camera 200 allows the driver of the vehicle 5 to observe the image of the field of view 502 and avoid a collision with the vehicle 50. As represented by the WLAN symbol, depending on the characteristics, the camera 200 comprises a transmitter 512. A receiver 520 with a display 522 has a receiver 514 also shown in Figure 5A by the symbol WLAN. In accordance with typical embodiments, the receiver 520 is a navigation system, a computer tablet, a smartphone, or a vehicle electronics, for example, the on-board computer of a vehicle. Thus, the display 522 of the receiver 520 displays the image of the camera 200. In the case of a receiver constituted by the electronics of the vehicle 5, the vehicle display can be used. Depending on the features, the transmitter or receiver is a wireless transmitter or receiver. For example, transmission can be via WLAN, Bluetooth or ZigBee. According to other embodiments, the transmitter 512 also has a receiver function and / or the receiver 514 also has an emitter function. Thus, for example, the communication between the two cameras 200 and the receiver 520 is allowed to be communicated. FIG. 5B shows another situation that is encountered while driving for a windscreen wiper device equipped with a broom. wiper 2 and at least one camera 200 usable advantageously. FIG. 5B shows a windscreen wiper device with two cameras 200. The arrow in FIG. 5B indicates that the vehicle 5 forwards, for example, to exit a parking space bordered by walls 507. The two cameras 200 seize the traffic for the reverse maneuver with the respective 502 field of view. Thus, one improves considerably, the reverse for example, the exit of garage with very low visibility or a building exit, which globally improves the circulation. This is particularly the case of a wiper device equipped with two cameras which, according to the characteristic embodiments, can be positioned or moved for the wiper device in the middle of the field of view. Thus the cameras of the left zone and the right zone, that is to say a field of view 502 directed to the left and then a field of view 502 directed to the right, allow to have an overview . Typically, the wiper blade is perpendicular, i.e. the sighting fields 502 have a substantially horizontal optical axis (e.g., horizontal +/- 15 °). The transmission is done with two video camera images. The lateral capture of an image with a camera integrated in a wiper device can nevertheless be done with a camera, at least in one direction. According to one characteristic, the windscreen wiper device allows movement in the receiving position of the camera. Thus, the control device of a windscreen wiper device is used which, in the rest position of the rear window wiper device, is in the central region of the rear window, substantially at the middle of the rear window. A camera integrated in a windscreen wiper device can be rotated to have the 502 lateral sighting image. As shown in FIG. 5B, two cameras 200 installed in the wiper direction can also be used to have a field of view 502 in both directions. Such a function increases the security for the rear steps to exit for example from a garage entrance or a building entrance because of road traffic that is aimed at least in one direction and even preferably in two directions. Fig. 6 shows an embodiment for integrating a camera 200 into a windshield wiper device. This embodiment can be combined with other embodiments. FIG. 6 shows a portion of the windscreen wiper device comprising an upper part 10 and a fixing piece 30. The attachment piece 30 has at least one opening 630 into which a plug-in mechanism 622, for example a pin or a sleeve. The plug-in mechanism, for example, hooks into the aperture 630. The optics 620 or lens of the camera protrude from the fixture 30 to have a sufficiently large field of view.
[0011] Figure 6 shows a side view of the fastener 30 or windshield wiper device. According to one feature, an opening 630 is alternatively or additionally provided on the opposite side of the fastener 30. Thus, a camera 200 with a plug-in mechanism 622 may be provided additionally or alternatively on the opposite side. This embodiment makes it possible to have an assistance camera with parking maneuvers for the parking position on the left or the parking position on the right. In addition, in the case of a respective camera with opposite ports 630 on the connecting piece 30, there will be monitoring on both sides for the reverse as has been described for example in connection with FIG. 5B. Figure 7A shows another embodiment of the integration of a camera 200 in a wiper device 100. Figure 7A shows a fastener 30 of a windshield wiper device.
[0012] The respective sides of the fastener comprise an actuating device 21 for releasing the quick-closing connection. Alternatively, there may also be other actuators such as, for example, in other embodiments described herein for the wiper device of Figure 7A. Figure 7A is a perspective view of a portion of the wiper device and a section of the plug mechanism. The wiper device comprises a plug-in mechanism 720 constituted for example by a rotary ring. For example, the windscreen wiper mechanism or the rotary ring are integrated in the attachment piece 30. As indicated by the arrow 701, the sliding mechanism 720 makes it possible to rotate the camera 200. can be provided on the respective sides, which allows the camera to rotate between a storage position on the right and a storage position on the left. According to another characteristic, it is possible to adjust the position of the camera, for example continuously between a storage position on the left and a storage position on the right. The position of the camera can thus be adapted to the vehicle geometry, particularly in the case of retrofitting, to have the appropriate field of view. For example, for very steep rear windows, the camera can be positioned in the middle, to allow you to look at the road behind the vehicle. Figure 7B shows another embodiment for integrating a camera 200 into a wiper device. The cap 200 comprises a hinge 701, for example a ball joint. This articulation makes it possible to orient the optics 202 of the camera 200. The housing 204 as a ball joint makes it possible to rotate the windscreen wiper device in the connecting piece 30. It is thus possible to orient the optical axis. The ball joint also allows rotation about the optical axis. This rotation rotates the image of the camera on the receiver screen. According to one characteristic, the camera can be adjusted by a precision adjustment by rotation using a four-sided wrench. FIG. 7B shows, for example, an aperture 702 for a hex key or Allen wrench 702 'of another allen plug key for setting the optics 202 of the camera. For example, you can have a rotation around the three axes or make a fine adjustment using an allen key or another multi-cavity socket wrench. According to other embodiments, the camera can be rotated, for example by means of a ball joint, that is to say, for example to perform an adjustment along three axes also combined with possibilities. integration not described here, especially by the integration of a camera 200 in a wiper device as has been shown in Figures 6, 7A. FIG. 8 shows another embodiment of a windscreen wiper device incorporating a camera 200 according to the embodiments described above. The wiper device with a wiper blade 2 is attached to a vehicle to wipe the window 4, for example the rear window. The wiper blade 2 rotates about the axis 850. The embodiment shown in FIG. 8 includes a fastener 830 which corresponds to the fastener 30 of the other described embodiments. The windshield wiper device is attached to the vehicle by means of the fastener 830. According to features, the fastener 830 is asymmetrical with respect to the axis 850. The camera 200 can thus be the distance 832. The reference 801 shows the position of the camera for a symmetrical embodiment of the fastener. The asymmetrical shape of the fastener 830 allows the camera 200 to be slid from the distance 802 and 832. The zone bearing the reference 804 constitutes a disturbing edge which corresponds to the shape given to the vehicles. Thus, the asymmetrical embodiment of the fastener 30 transforms the usual field of view 502 into a modified field of view 802. The respective changes in the field of view are represented by the arrows 834. To improve the visibility on the roadway, it is possible to give the shape of the wiper device or a component of the wiper device, such as for example the fastener, an asymmetrical shape in the camera area. The position of the camera is thus shifted, especially with respect to the axis of rotation 850 of the wiper device. This results in a better visibility range, for example, over the disturbing ridge at the rear of the vehicle. According to embodiments described herein which can be combined with other described embodiments, a component of a windscreen wiper device equipped with the camera is asymmetrical to allow a variation of position of the camera 200, in particular by relative to the axis of rotation 850 of the windscreen wiper device. Typically, the components of the windshield wiper device are from the fastener part of the wiper device which makes it possible to attach the windshield wiper device to the vehicle. Figs. 9A and 9B show typical systems of electrical realization of a camera integrated into a wiper device. Figure 9A shows a system of an electrical construction integrating the camera into the wiper device; the camera constitutes an autonomous system, that is to say not connected to the on-board vehicle network. The display 522 is for example that of a navigation system, the display or the screen of a tablet or the screen of a smartphone or a display installed in the vehicle. The display or a receiving unit connected to the display comprises a receiver 514. The receiver may be a WLAN receiver 914, a Bluetooth receiver 514 and / or a ZigBee component (IEEE 802.15.4) forming a receiver 916. The transmitter 515 sends information from the camera 200.
[0013] The transmitter may be a WLAN transmitter 924, a Bluetooth transmitter 925 and / or a ZibBee transmitter (IEEE 802.15.4) 926. According to characteristic embodiments, the transmitter 515 is additionally provided as receiver and / or receiver 514 can be further equipped as a transmitter to allow for example a connection at least partial or total in two-way communication. In accordance with typical embodiments, the camera 200 is a digital camera that is optionally provided with an optical unit such as, for example, a lens, a zoom lens, or a digital zoom. The camera 200 is supplied with electric power by a power supply unit 930. The power supply unit 130 comprises, for example, a battery 933. Optionally at least one generator 931 and / or a photovoltaic cell 932 are provided.
[0014] According to typical embodiments that can be combined with other embodiments, the upper portion 10 includes a fin-ray wiper blade photovoltaic cell. The wide or flat surface of the upper part of the Fin-Ray wiper is suitable in comparison with conventional windscreen wiper devices, particularly for fixing a photovoltaic cell such as a flexible photovoltaic cell. . Alternatively or additionally, a generator is integrated in the windscreen wiper device; the generator transforms the wiper rotation movement into electrical energy to charge the accumulator 933. In particular, for a stand-alone system, ie a system not connected to the vehicle on-board network. the electrical structure can be established to control the camera 200 by an activation device 901 integrated in the camera. To protect the battery, the camera can be used in the power saving mode. According to the embodiments described a wake up function, that is to say an activation 901, will activate the camera. This activation is done for example by a maneuver made according to Bluetooth, WLAN or ZigBee (IEEE 802.15.4) to have reception according to the receiving device. Figure 9B shows another system of electrical construction for a camera integrated in a windshield wiper device.
[0015] The system is connected to the on-board network of a vehicle. The components, such as the display 522, the receiver 514, the transmitter 512 and the camera 200 can be made as the independent system. In the case of an injection into the on-board network of the vehicle, there will be no connection 945 of the rear window wiper at the rear lighting of the vehicle. The power supply will be with a connector 944 connected to the camera 200. Alternatively or additionally, the power supply will be by induction through the rear window 4 by an active transmitter 943 and an inductive energy receiver 941. In order to activate the camera, as in FIG. 9A, activation means 901 are used. This case is shown in FIG. 9B because at the connection to the vehicle network, the activation is typically carried out also by the 945 connection to the taillight. The activation can be done using the connector 944, as inductive power supply without using cable or the rear window 4 or redundantly by the power supply network. According to the embodiments described above, it is particularly advantageous to use Fin-Ray wiper devices for vehicle windows and / or for a large number of different fields of use. The embodiments described above of the wiper device allow a particularly good adaptation to the curvature of a window to have a particularly precise and clean wiping of the window. The unswashed areas of the glass and the formation of sail on the glass will be avoided to a very large extent. In addition, the constructive realization of the windscreen wiper device according to the invention makes it possible to have a very regular application pressure of the wiper device against the window, resulting in an excellent quality of wiping.
