    [0001] BACKGROUND OF THE INVENTION The present invention relates to the field of shutter flaps, a device for shuttering and a shutter device. shutter comprising such a shutter and a front-end module for a motor vehicle comprising such a device.
    [0002] State of the Prior Art A motor vehicle is commonly provided with an air intake located at the front of the vehicle and designed to cool the engine compartment. This cooling can be effected by means of a heat exchanger promoting heat exchange between the incoming air and a coolant. In other words, the air inlet allows the introduction of an outside air flow which cools the coolant, via the heat exchanger, as well as the engine.
    [0003] However, in certain situations, the engine compartment does not always need to be cooled, for example during the starting phase of the vehicle. In such situations, it is appropriate to incorporate an air shutter device that can be actuated on command, this so as to vary the flow rate of the incoming air flow, or even remove it when the engine n It does not need to be cooled. The closure device generally comprises a frame in which are arranged shutters able to obstruct the interior space of the frame. Generally known shutter devices are arranged behind the air inlet to not detract from the aesthetics of the vehicle. A grid having a purely aesthetic role, is usually added to the level of the air inlet.
    [0004] This arrangement however has a disadvantage. Indeed, the shutter device, being arranged behind the air inlet, thus generates a space congestion problem within the engine compartment.
    [0005] To remedy this, it has been proposed in the past to arrange the closure device directly on the outer front of the vehicle. However, this involves removing the ornamental grid which can affect the aesthetics of the vehicle by the visual appearance of the frame and shutters of the closure device. In addition, in order to maintain a uniform visual appearance, the shutters are made of a single material, generally polymers based on polyamides 6, however such a material is detrimental to the aesthetics of the vehicle. SUMMARY OF THE INVENTION The present invention aims to remedy these drawbacks and to propose a front end of a motor vehicle that is robust without adversely affecting the aesthetics of the vehicle. For this, the invention provides a shutter, in particular for a front air inlet 20 of a motor vehicle, comprising at least one structural element. According to the invention said flap comprises an additional element secured on at least one face of said structural element, the structural element and the additional element being made of two different materials, said flap being arranged so as to be visible from the exterior of the motor vehicle.
    [0006] In this way, the structural element obstructs the air intake of the front face of the vehicle while the additional element consolidates the structural element of the flap by offering a better mechanical resistance to the pressure of the flow of air. outside air. In addition, the additional element has an ornamental appearance so as to embellish the aesthetics of the motor vehicle. Particular embodiments according to the invention propose that: the structural element comprises an axis of rotation capable of pivoting the structural element, said structural element comprising a closure surface capable of obstructing at least one partially the air inlet; the additional element is made of polypropylene; The additional element is overmolded on the sealing surface; the additional element is overmolded on several faces of the structural element. The invention also relates to a closure device, in particular for a motor vehicle front face air inlet, comprising a support frame comprising at least one shutter flap as defined above. The invention also relates to a motor vehicle front end module comprising a bumper and a shutter device described above. According to the invention, the additional element is made in the material that the bumper of the motor vehicle. BRIEF DESCRIPTION OF THE FIGURES Other features and advantages of the invention will emerge on reading the description which follows, with reference to the appended figures, with: FIG. 1 illustrates a side view of a motor vehicle; - Figure 2 illustrates a side view of a closure device; FIGS. 3A and 3B illustrate a side view of a shutter according to the invention; - Figures 4A to 4D illustrate a side view of a shutter according to different embodiments of the invention. DETAILED DESCRIPTION OF EMBODIMENTS A motor vehicle 2, as illustrated in FIG. 1, comprises a motor compartment 4 in which various components, such as a motor and heat exchangers not shown here, are housed. The motor vehicle 2 comprises on a front face 5 an air inlet 6 allowing an outside air flow F to enter the interior of the engine compartment 4 and thereby cool the various components, including heat exchangers . An obstruction device 8, which will be described later, is arranged at the air inlet 6 on the front face 5 of the motor vehicle 2, in other words directly on the outer front surface of the motor vehicle 2 , and makes it possible to vary the flow rate of outside air flow F entering the engine compartment 4. Of course, the obstruction device 8 is able to completely obstruct the air inlet 6 so that the flow external air 10 F can not penetrate into the engine compartment 4. The motor vehicle 2 comprises a bumper 10 disposed within the body of the front face 5 of the motor vehicle 2. The bumper 10 corresponds to an insert, for example a beam, made of deformable material designed to absorb the maximum energy during an impact, thanks to the deformation of the material, so as to protect the motor vehicle 2. The bumper 10 is a piece made either metal or plastic, however it is preferable, for weight constraints, to install plastic bumpers, for example polypropylene, on the motor vehicle 2.
    [0007] The bumper 10 is an important element of the motor vehicle 2, located towards the middle of the front face 5 of the motor vehicle 2, so as to better protect the vehicle in the event of an accident. Therefore, generally two air inlets 6 are arranged on either side of the bumper 10 so as to maintain a bumper 25 10 on the vehicle without reducing the flow rate of the incoming air flow F in the engine compartment 4. The invention is not limited, however, to the number of air inlet 6 arranged on the front face 5 of the motor vehicle 2. In fact, it is conceivable to have a motor vehicle 2 with a single air intake 6 arranged for example above the bumper 10, or a vehicle with two air inlets 6 arranged on either side of the bumper 10 as shown in Figure 1.
    [0008] The shutter device 8 as illustrated in FIG. 2 comprises a frame 12 inscribed in the bodywork of the front face 5 and several shutter shutters 14 capable of pivoting between two extreme positions, a so-called "closed" position. Where the air flow F can not pass through the air inlet 6 and therefore can not penetrate into the engine compartment 4, and a so-called "open" position where the air inlet 6 is disengaged so that the air flow F can pass through the passage of the frame 12 and penetrate into the engine compartment 4. Of course, each shutter 14 is adapted to adopt any intermediate position positions The invention is not limited to the number of shutters 14 shutter present in the device. Indeed, it is conceivable to have a system with a single flap covering the entire air intake surface.
    [0009] The shutter shutters 14, as illustrated in FIG. 2, are rotated about an axis A by an actuator 16. The actuator 16, under the effect of a control that can be pneumatic, electrical and / or mechanical, causes a first shutter shutter 14 according to a rotary movement defined around the axis of rotation, at a defined angle, for example in a range from 0 to 20 900. A movable rod 18 secured this first closure shutter 14 is then moved in a translational movement represented by the axis B. The movable rod 18, being integral with each shutter shutter 14, causes the other shutters 14 shutter in the same configuration that the first shutter shutter 14 so as to have all the flaps 14 in the same position called "open".
    [0010] The closure flap 14 according to the invention, and as illustrated in FIG. 3A, comprises a structural element 20. The structural element 20 comprises reception means 24, here corresponding to arms, of a rotation means 22, for example a rod, which is rotated by the actuator 16 or the movable rod 18. The rotation means 22, driven by the actuator 16, causes the rotation of the structural element 20 to move from an open position passing the air flow F as shown in Figure 3B, to a closed position obstructing the passage of the air flow F, as shown in Figure 3A. In other words, the closing shutter 14 comprises a rotation means 22 capable of rotating the structural element 20 and in particular a sealing surface 28 capable of at least partially obstructing the air inlet. 6 and thus the passage of the air flow F within the engine compartment 4.
    [0011] The closure flap 14 comprises a rotation means 22 and a structural element 20. The rotation means 22 may be made of metal, such as aluminum or steel, or of rigid plastic, that is, any suitable polymer such as polyamide 6 (poly (hexano-6-lactam) or nylon 6) for example. However, for weight constraints, it is better to opt for a rigid plastic.
    [0012] The structural element 20 can also be made of metal, such as aluminum or steel, made of rigid plastic, that is to say, any suitable polymer such as polyamide 6 or fiber filled material. . The closure shutter 14 according to the invention also comprises an additional element 26 attached to at least one face of said structural element 20 and in particular to the closure surface 28. The additional element 26 corresponds to a layer made in one embodiment. different material from that of the structural element 20. As shown in Figure 3A, at least one of the flaps is arranged near the bumper 10, so that when the engine compartment 4 does not need To be cooled, the closure shutter 14 adopts a so-called "closed" position so as to obstruct the air inlet 6. The external appearance of the motor vehicle varies according to the material of the additional element 26 since the device shutter 8, and therefore the shutter 14, 25 are arranged to be visible from outside the motor vehicle. In order to give a more homogeneous, and therefore more aesthetic, visual appearance to the front of the motor vehicle, the additional element 26 is made of the material that the bumper 10 of the motor vehicle, namely polypropylene. The realization of the additional element 26 made of polypropylene will not only make it possible to guarantee an appearance and surface condition identical to the outside of the vehicle with the same finishing possibilities, as for example the paint, but it also ensures a better mechanical strength. and pressure resistance of the outside air flow.
    [0013] FIGS. 4A to 4B illustrate shutter shutter 14 according to the invention according to other embodiments. As illustrated in FIG. 4A, the structural element 20 may be overmolded around the rotation means 22 in order to stiffen the assembly. According to FIG. 4B, the additional element 26 may be overmolded on several faces of the structural element 20, here three. According to FIG. 4C, the additional element 26 may be overmolded in a partial manner on all the faces of the structural element 20. Finally, according to FIG. 4D, the additional element 26 may be overmolded on the entire element. of structure 20.
    [0014] The invention also relates to the closure device 8, in particular for an air intake 6 front face 5 of a motor vehicle 2, comprising a support frame 12 comprising at least one shutter 14 shutter as described above. The invention also relates to a front end module 5 of a motor vehicle 2 comprising a bumper 10 and a closure device 8 as previously described. According to the invention, the additional element 26 is made of the material that the bumper 10 of the motor vehicle 2. It should be understood, however, that these exemplary embodiments are given by way of illustration of the object of the invention. the invention. The invention is not limited to these embodiments described above and provided solely by way of example. It encompasses various modifications, alternative forms and other variants that may be considered by those skilled in the art within the scope of the present invention and in particular any combination of the various embodiments described above. 25
