    [0002] The invention also relates to an injection tool for the manufacture of a plastic part and a method of manufacturing such a plastic part, in particular a wiper blade component. STATE OF THE ART Plastic parts such as windscreen wiper components having a body made of injected material and at least one coding unit are already known. There is also known a method of manufacturing such a room. DESCRIPTION AND ADVANTAGES OF THE INVENTION The subject of the present invention is a plastic part, in particular a wiper blade component having an injected body and at least one coding unit, this part being characterized in that the coding unit comprises at least one integrated matrix code in the body of injected material and containing at least one coded information. In other words, according to the invention, the plastic part, in particular the wiper blade component has a body of injected material and a coding unit with at least one matrix code. This code is integrated in the injected body to memorize at least one coded information. This makes it possible to advantageously and unequivocally connect the body with injected material. The injected material body can be advantageously identified at any time in a machine-readable manner in a production line. This advantageously reduces the risk of inversion of different components in plastic material. The plastic component may be the end cap of a wiper blade, a wiper blade, a baffle, a wiper blade adapter and / or any other technically interesting component. .
    [0003] In this context, it is also possible to consider as a wiper blade component other technically interesting components of a windscreen wiper blade. The coding unit is a unit that makes it possible to memorize and / or transmit at least one piece of information. The matrix code according to the invention is a two-dimensional optical code containing at least one coded, readable information. Advantageously, the matrix code corresponds to the definition of the international standard ISO / IEC 16022: 2006. The coded information advantageously comprises a serial number.
    [0004] The term "intended for" according to the invention means a means specially designed and / or designed to provide a certain function. The fact that an object is provided for a certain function means in particular that the object performs and / or performs a certain function in at least one application and / or for at least one operating state. According to another development of the invention, the matrix code is at least one cavity and / or at least one modification of the structure of the surface of the injected material body. This very advantageously avoids that the matrix code can be detached from the injected body. It is furthermore avoided to have to work subsequently the injected material body, which advantageously reduces the manufacturing cost of the component or plastic component. According to another characteristic, the injected body has a captive matrix code, which advantageously reduces the risk of inadvertent detachment of the matrix code. According to another characteristic, the matrix code is integrated during the injection process, which achieves a particularly reliable integration of the matrix code in the injected body and further advantageously reduces any risk of subsequent confusion.
    [0005] This avoids other devices for applying matrix codes, including printing devices. According to another characteristic, the matrix code includes an ECC200 error correction, which advantageously makes it possible to correct reading errors, especially if the matrix code is damaged. The ECC200 correction code according to the present description designates an error correction code, based on the Reed-Solomon code. According to another characteristic, the matrix code has a dimension of at least 10 × 10 fields, which makes it possible to store a very large quantity of information in a coded manner. Preferably, the matrix code has a size of at least 15 × 15 fields and in particular preferably a dimension of at least 25 × 25 fields. Preferably, the fields are rectangular and especially square.
    [0006] According to another development of the invention, the body injected is a plastic component which allows a particularly simple and economical manufacture of the injected material body. The invention also relates to an injection tool with at least one code printing relief for integrating matrix code into a wiper blade component by an injection method which advantageously reduces the risk. integration of coded information, erroneous. This also reduces the cost of manufacture and advantageously increase the speed of production. According to another characteristic, the coded printing has a dimension of at least 10 mm 2, which makes it possible to apply the coded information advantageously to small components. In addition and advantageously, the coded information is applied in a particularly discrete manner on the injected material body. The invention also relates to a method of manufacturing a wiper blade component with an injection tool consisting of applying a matrix code to a body of material injected during an injection, which allows for particularly fast and economical identification of the wiper blade component. In addition, and advantageously, any risk of confusion is avoided during another stage of the manufacturing process. In addition, the matrix code is integrated into the body in injected material. The wiper blade component according to the invention is not limited to the application and the embodiment envisaged above and in particular the number of parts, of separate elements, the component and the detail of the broom. of wiper according to the invention may differ from what has been described above. Drawings The present invention will be described below, in more detail with the aid of an embodiment of a plastic component, in particular a wiper blade and its manufacturing method according to the invention. The invention shown in the accompanying drawings in which: - Figure 1 is a partial perspective view of an ice-soap wiper and a plastic component, - Figure 2 shows the plastic component. FIG. 1 is a representation of a matrix code of a coding unit, and FIG. 4 shows an injection tool for FIG. manufacturing the plastic component according to Figure 2 by a detail perspective representation. DESCRIPTION OF THE EMBODIMENT FIG. 1 shows a partial perspective view of a wiper blade 20 provided with a plastic component. The plastic component is a wiper blade component 10. The wiper blade 20 is a flat wiper blade. The wiper blade 20 serves to clean a vehicle window not shown, being moved by a pendulum movement on the window. For this, the wiper blade 20 has a wiper lip 26 and a baffle 28. The baffle 28 extends from the wiper blade adapter, not shown to the free end 30 of the wiper blade 26. Another deflector element not shown is installed on the opposite side of the wiper blade adapter. The wiper blade 26 for wiping a vehicle window has a wiper lip 32. The wiper blade 26 is made of extrusion made of a rubber material. The deflector 28 serves to deflect the incident air stream and generate an application force 28 exerted on the wiper blade 26 in the direction of the vehicle window.
    [0007] The deflector 28 is made of a rubbery material. The deflector 28 has a concave attack surface 34. The deflector 28 extends over a large part of the longitudinal extension of the wiper blade 26. The deflector 28 further has claw-shaped fasteners, not shown, for securing the wiper blade 26. The wiper blade component 10 is installed at the free end 30 of the wiper blade 26. The component 10 constitutes an end cap. The wiper blade component 10 has a body 12 injected. The injected body 12 is a piece of plastic material.
    [0008] In this case, it is conceivable to produce the plastic part made of a pure plastic material or a plastic material with an additive, especially fibers and / or mineral additives. In the exemplary embodiment shown, the injected material body 12 completely constitutes the wiper blade component 10. The injected material body 12 is made in one piece. As shown in Figure 2, the injected material body 12 has a coding unit 14. The coding unit 14 is on the side of the injected body 12 facing the vehicle window. The coding unit 14 has a data matrix 16. In this context, it is also possible to envisage a coding unit 14 having other matrix codes. The matrix code 16 corresponds to the definition of the international standard ISO / IEC 16022: 2006. The matrix code 16 is integrated in the injection body 12. More specifically, the matrix code 16 is integrated into the injected body 12 during an injection operation so that the matrix code 16 is associated with captively to the injected body 12. The matrix code 16 contains coded information. This coded information in this case includes a serial number. In principle, it can also be envisaged that the matrix code 16 includes other technically interesting coded information such as, in particular, a date of manufacture, a factory number, a color information and / or material information. The matrix code 16 has an ECC200 correction code. In this context, it is also possible to envisage a matrix code 16 having another technically interesting correction code and / or an implementation information item.
    [0009] As shown in more detail in FIG. 3, the matrix code 16 comprises a set of fields 36, 38. In the example presented, the matrix code 16 has a dimension of 10 × 10 fields 36, 38. context, one can also consider for the matrix code 16 a dimension of at least 15 x 15 fields or at least 25 x 25 fields. Fields 36, 38 are square. Depending on the type of matrix code 16, it is also possible to envisage other shapes, in particular rectangular, circular, trapezoidal and / or parallelogram shape shapes 36, 38. Some fields 36 are presented darker than other fields 38. The brightest fields 38 have a different binary value than the darker fields 36. For the sake of clarity, not all fields in FIG. references. The matrix code 16 allows reading by a calculation system using a camera. The coding unit 14 realizes the matrix code 16 with sufficient color contrast. This is achieved for example with different surface properties by particle size and / or scratches. The matrix code 16 is made in part as a recess 18 in the injected body 12. In the exemplary embodiment shown, all the light fields 38 are in relief while the dark fields 36 are located deeper in the body. In addition or alternatively, the matrix code 16 is then processed by a color application consisting of lightening for example the most forward 38 fields. Fields 36 located deeper keep a darker shade. The injected body 12 is made by injecting plastic material into an injection tool or injection mold 22. The injection tool 22 comprises, as shown in FIG. 4, a coding printing 24. The printing of FIG. coding 24 is made in one piece with the injection tool 22, which associates integrally and unchangeable, coding printing 24 to the injection tool 22. In principle, it is also possible to envisage a coding print 24 removably associated with the injection tool 22. The coding print 24 prints a matrix code 16 in the wiper blade component 10 during the injection.
    [0010] The coding printing 24 has dimensions less than 10 mm 2. More specifically, the coding printing 24 has a dimension of 3 mm x 3 mm. In this context it is also possible to envisage a coding printing 24 having another technically interesting dimension.
    [0011] According to the method of manufacturing the wiper blade component 10 with an injection tool 22, the matrix code 16 is introduced into the injected body 12 during the injection operation. The injected body 12 is thus produced at the same time as the coding unit 14. In this context, it is also conceivable to subsequently form the matrix code 16 on the injected body 12. In order to separate the coding unit 14 from the injected body 12 at least partially destroy the injected body 12 which renders it unusable. 15 8 NOMENCLATURE OF THE MAIN COMPONENTS 10 Wiper Blade Component 12 Injected Body 16 Die Code 18 Hollow 20 Wiper Blade 22 Injection tool / injection mold 24 Coding printing 26 Wiper blade 28 Deflector 30 Free end of wiper blade 36, 38 Code fields in matrix 15
