    [0001] The present invention relates to shut-off devices and more specifically to a device for closing the air inlet of the front face of a motor vehicle. The front faces of motor vehicles are generally composed of two main air inlets called high and low track separated by a bumper beam. Behind this bumper beam are generally placed the heat exchangers of the motor vehicle, such as that used for the air conditioning of the passenger compartment or that used for cooling the engine. It is also known to have, in the air path passing through the main air intakes, more generally the lower channel, a support frame comprising a multiplicity of flaps pivotally mounted about parallel axes and adapted to take a multiplicity different angular positions, between an open position and a closed position, under the action of appropriate control means. This gives a closure device similar to a jalousie that adjusts the air flow through the air inlets and arriving at the heat exchangers and thus optimize the efficiency of these heat exchangers depending on the needs. In addition, at high speed, shutters in the closed position can reduce the drag coefficient of the vehicle and improve its aerodynamics. Generally, the device allowing the passage of a closed position to an open position of the flaps comprises an actuator which can be mechanical, electrical or pneumatic, rotating the flaps in synchronism by means of a pivot rod . 3037283 2 However, during the rotation of the flaps, the rod causing them performs a translational movement on two axes, in height and depth. This movement on two axes and in particular the movement in depth requires the development of a free space to allow this movement and therefore the closure device must have a certain thickness thus complicating the mounting of said closure device on the front face. In addition, there is a constant demand from manufacturers to reduce the size of the elements of a motor vehicle, especially along the longitudinal axis of said vehicle.
    [0002] One of the aims of the present invention is therefore to at least partially overcome the disadvantages of the prior art and to provide an improved closure device. The present invention therefore relates to a closure device, in particular for a motor vehicle front-end air intake, comprising: a support frame in which a set of pivoting flaps is installed between a shut-off position and a position of opening, - at least one control element controlling the positioning of the flaps and comprising: an actuator, a sliding element comprising at least a first rack, the flaps comprising at at least one of their ends a pinion placed on their pivot axis and meshing with the first rack. The fact of using such a control element notably allows a space saving in depth. Indeed, a control element using a connecting rod, must have a sufficient thickness to allow said connecting rod to make a movement in depth when moving height to open or close the shutters. The control element according to the invention does not need to provide a movement in depth because the sliding element moves only in height. The shutter device according to the invention can thus be thinner and therefore take up less space within the front of the motor vehicle.
    [0003] According to one aspect of the invention, the actuator comprises an output gear and the sliding member comprises a second rack meshing with the output gear of the actuator. According to another aspect of the invention, the output pinion rotates about a rotation axis perpendicular to the general plane defined by the pivot axes of the flaps and that the second rack is then oriented so that its teeth point in a parallel direction. in the general plane defined by the pivot axes of the flaps to mesh with the output gear.
    [0004] According to another aspect of the invention, the sliding element comprises a window whose one edge carries the second rack. According to another aspect of the invention, the closure device comprises two sets of flaps and the control element is placed between said sets of flaps, the sliding element comprising two second racks, each being meshing with the sprockets of the flaps. shutters of a set of shutters. According to another aspect of the invention, between the output gear and the flap gears, the transmission ratio is less than 1.
    [0005] Other features and advantages of the invention will emerge more clearly on reading the following description, given by way of illustrative and nonlimiting example, and the appended drawings in which: FIG. 1 shows a diagrammatic representation in front perspective of a closure device in the closed position, - Figure 2 shows a schematic representation in perspective and in section of the closure device of Figure 1, 5 - Figure 3 shows a schematic representation in FIG. perspective of a control element The identical elements in the different figures bear the same references.
    [0006] The following embodiments are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the features apply only to a single embodiment. Simple features of different embodiments may also be combined to provide other embodiments. In the present description, it is possible to index certain elements or parameters, for example first element or second element as well as first parameter and second parameter, or first criterion and second criterion, and so on. In this case, it is a simple indexing to differentiate and name elements or parameters or criteria close but not identical. This indexing does not imply a priority of one element, parameter or criterion with respect to another, and it is easy to interchange such denominations without departing from the scope of the present description. This indexation does not imply an order in time, for example to evaluate one or other criteria. Figures 1 and 2 show a schematic representation in perspective of a closure device 1 in the open position (Figure 1) and in the closed position (Figure 2). Said shutter device 1 comprises a support frame 5 on which is installed at least one shutter assembly 3. The shutters 3 can pivot about generally parallel axes of rotation defined by their connection with the support frame 5. On the different figures, this pivot axis A is parallel to the Z axis of the XYZ trihedron represented, that is to say on the width of the motor vehicle. The X axis of the trihedron 5 corresponding to the longitudinal axis of the motor vehicle and the Y axis at its height. Within this set of flaps 3, said flaps 3 are superimposed and arranged parallel to each other. By superimposed means that the flaps are aligned on the Y axis. In other words, the flaps 3 are arranged in such a way that they pivot between two positions, a shut-off position where the air inlet is completely integral. obstructed so that an air flow can not pass through the air inlet, and an open position where the air inlet has a space for passage for airflow. At one end of the shutters 3 is placed a control element 7 allowing the rotation of the shutters 3 between an open position, illustrated in Figure 1, where the shutters 3 are oriented so that an air flow may pass through the closure device 1 and thus penetrate into the vehicle such as in the engine compartment, and a closed position shown in Figure 2, where the flaps 3 are oriented so that a flow of air can not pass through the shutter device 1. It is possible to have a shutter device 1 of a motor vehicle front face air inlet having a plurality of flap assemblies 3 extending over the entire width of the support frame 5. Two sets of flaps 3 can thus be separated by a control element 7 in order to ensure their synchronous rotation as shown in FIGS. 1 and 2. The control element 7 comprises an actuator 71 The actuator 71 can be elec such as an electric motor. Said actuator 71 is connected to an output gear 75 which it drives. The control element 7 also comprises a sliding element 73 comprising a second rack 77 meshing with the output gear 75 of the actuator 71. As a result, when the actuator 71 emits a rotational movement, the actuator 71 can not be rotated. causes the sliding element 73 to slide through the pinion / rack connection uniting them. Obviously the invention is not limited to the use of rack and pinion. We could consider using, according to a non-illustrated embodiment, any means operating by shape complementary, such as for example a notch located within the sliding element and a hook connected to the actuator displacing the sliding element and allowing thus to rotate the flaps between a closed position and an open position of the air inlet. To save space, the sliding element 73 is preferably a movable plate 10 pressed against the closure device and which slides parallel to the plane connecting the axes of rotation A flaps 3, or along the Y axis of the trihedron. The flaps 3 further comprise, at at least one of their ends, a pinion 31 placed on their pivot axis A and meshing with a first rack 79 of the sliding element 73.
    [0007] Since all the shutters 3 are connected to the sliding element 73, the passage from an open position to a closed position is synchronous for all said shutters 3. Indeed, the sliding of the sliding element 73 under action of the actuator 71 causes the synchronous rotation of the flaps 3 from the pinion / rack connection between the flaps 3 and the sliding element 73, as illustrated in FIG.
    [0008] The fact of using such a control element 7 allows in particular space saving in depth, that is to say along the X axis of the trihedron. Indeed, a control element 7 using a connecting rod, must have a sufficient thickness to allow said rod to make a movement along the X axis during its movement along the Y axis to open or close the shutters. The control element 7 according to the invention does not need to provide a movement along the X axis since the sliding element 73 only moves along the axis Y. The closure device 1 according to the the invention can thus be thinner and therefore take up less space within the front of the motor vehicle.
    [0009] As shown in the various figures, the output gear 75 can rotate along an axis of rotation parallel to the X axis of the trihedron, ie perpendicular to the general plane defined by the pivot axes A of the flaps 3. The second rack 77 is then oriented so that its teeth point in a direction parallel to the general plane defined by the pivot axes A of the flaps 3 in order to mesh with the output gear 75. Still with the aim of minimizing the thickness of the shutter device 1 and in particular of its control element 7, the sliding element 73 may comprise a window 700, one of whose edges has the second rack 77.
    [0010] The output gear 75 is inserted at least partially into the window 700 in order to mesh with the second rack 77. According to a non-illustrated embodiment, we can envisage an opposite case where the output gear 75 can rotate according to a axis of rotation parallel to the Z axis of the trihedron, or parallel to the general plane defined by the pivot axes A flaps. The second rack 77 is then oriented so that its teeth point in a direction perpendicular to the axis of pivot A flaps 3 to mesh with the output gear 75. It is also possible to arrange two control elements at each end of the closure device to disengage the central space according to a non-illustrated embodiment. The shutter device 1 may comprise two sets of shutters 3 as shown in the various figures. The control element 7 is then placed between said sets of flaps 3 and the sliding element 73 comprises two second 25 racks 79. Each of these second racks 79 is meshed with the gables 31 of the flaps 3 of a set of flaps 3 for synchronous rotation of said shutters 3.
    [0011] Between the output pinion 75 and the shutter pinions 3, the transmission ratio may be less than 1. This transmission ratio allows the use of a less powerful and therefore less expensive actuator 71 which, however, because of this ratio transmission is sufficient to transmit enough force to rotate the flaps 5 3 and even if they are for example held glued by freeze in cold conditions. This transmission ratio of less than 1 can be obtained by having pinions 31 of flaps 3 and an output gear 75 of different diameters or having a different number of teeth.
    [0012] Thus, it is clear that the closure device 1 according to the invention, because of its particular control element 7, is thinner than the prior art and therefore allows easier integration within the motor vehicle.
