Other features and advantages of the invention will appear in the description which will now be made, with reference to the accompanying drawings which represent indicative but not limiting, a possible embodiment. In these drawings: - Figure 1 shows a side view and in section of a key according to a first embodiment of the present invention; Figure 2 shows a side and sectional view of a key according to a second embodiment of the present invention; - Figure 3 shows an isometric view of the movable elements of a plurality of control keys and their plate. In these figures the same reference numerals correspond to elements having the same function. The present invention relates to a control device 1 comprising at least one key. The control device 1 is intended to be inserted on a control panel 5, in particular a control panel 5 of a motor vehicle. FIG. 1 shows a sectional and side view of a key 3 of such a control device 1. The key 3 is inserted in the control panel 5 and comprises an element 7 movable between a rest position and a control position. The movable member 7 has an inner portion 9 located behind the front 5 and an outer portion 11 which protrudes out of the control front 5 through an orifice 13 of said front 5. The outer portion 11 corresponds to the part on which the user has just pressed to activate or deactivate the command associated with the key 3. The outer part 11 comprises, at its end, a function indicator 39 which is lit by a backlighting means 25 when the function associated with the control key 3 is activated. The backlighting means 25 is for example made by a light emitting diode. According to another embodiment, this function indicator 39 may serve as a locator for locating the control key 3 so that its illumination is then independent of the activation state of the function associated with the control key 3. Activation of the backlighting means 25 may then be related to the activation of the vehicle lights or be performed as soon as the user starts the engine of the vehicle or be linked to a dedicated command. According to a further embodiment, the function indicator 39 may be illuminated with a first color when the function associated with the control key 3 is inactive and with a second color when the function associated with the control key 3 is active. .

In this case, the backlight means 25 will comprise two light emitting diodes having distinct colors. In addition, the outer portion 11 and the inner portion 9 of the movable member 7 facing the function indicator form a light guide 27 which transmits the light from the backlighting means 25 located behind the control key 3 and opposite the function indicator 39 to said function indicator 39. The light guide 27 is for example made of polycarbonate or polymethylmethacrylate. The inner part 9 of the mobile element 7 also comprises a support 29 which extends in a plane substantially parallel to the front wall 5 and which is connected to a plate 31 at a pivoting end 30 distal to the light guide. (27) and the outer portion 11 of the movable member 7. The connection between the movable member 7 and the plate 31 is offset relative to the outer portion 11 of the movable member 7 which is supported by the user.

According to a first embodiment of the pivot connection shown in FIG. 1, the connection between the pivoting end 30 of the support 29 and the plate 31 is formed by a hinge connection 33 which pivotally guides the movable element 7 between its rest position and its control position. The support 29 is for example made of plastic and supports the light guide 27. The assembly between the light guide 27 and the support 29 is, for example, made by interlocking the light guide 27 in an orifice of the support 29 However, the assembly can also be achieved by clamping the support 29 around the light guide 27, by gluing, clipping, overmolding or by double injection molding. Both materials are injected one after the other in the same mold thus obtaining a single piece made with two different materials. According to a second embodiment of the pivot connection shown in Figure 2, the connection between the pivot end 30 of the support 29 and the plate 31 is formed by a mounting connection 34 in which the pivot end 30 is embedded in a groove 36 formed in the plate 31. In this case, the pivoting of the movable member 7 is formed by the bending of the support 29. In addition, it should be noted that the embedding can be oriented differently, the support 29 may for example comprise an advance that extends perpendicularly to the axis of the support and which fits into a horizontal slot of the plate 31. The recess connection 34 allows the maintenance of the movable member 7 when pivoting under the effect of the support of the user and provides the spring effect of the elastic return in the rest position when the user releases its support. On the other hand, the surface of the outer portion 11 is painted or chromed with the exception of the function indicator 39 so that light from the backlighting means 25 leaves the light guide at the function indicator 39. To achieve function indicator 39, a mask may be used when applying paint or chrome or laser scraping may be performed after applying paint or chrome to remove paint or chrome at the level of 39. Other state-of-the-art methods for obtaining the function indicator 39 may also be used. The control key 3 also comprises a control means 15 actuated by the movable element 7 and in particular by the displacement of the movable element 7 between its rest position and its control position. The control means 15 is for example made by an electrical contactor on which the movable member 7 comes to press in the control position. The control means 15 may be placed near the end of the movable member - 7 - 7 opposite to the hinge link 33 as shown in Figure 1, however, other locations may also be considered. The control means 15 can also be realized by an optical detector, an ultrasonic detector, a Hall effect detector or any other device of the state of the art for detecting the passage of the mobile element 7 from its position of rest at its command position. The activation signal can be created during the passage of the movable element 7 in the control position or when it returns to the rest position, that is to say when the user releases the control key 3.

The control key 3 also comprises a pictogram 17 situated in an area adjacent to the outer part 11 so that the user associates the pictogram 17 with the control key 3. In the case of FIG. 1, the pictogram 17 is on the facade in a portion adjacent to the outer portion 11, that is to say above this outer portion 11. In addition, so that the user can easily recognize the pictogram 17 regardless of the light conditions, a backlighting means 19 of the pictogram 17 is also placed behind the frontage 5 and facing the pictogram 17. However, since the backlighting means 19 is behind the support 29 of the mobile element 7, a transparent or translucent portion 21 is arranged in the support 29 opposite the pictogram for passing the light from the backlight means 19 to the pictogram 17. This transparent or translucent portion 21 is for example made by r an opening 22 in the support 29 next to the pictogram 17. The activation of the backlighting means 19 of the pictogram 17 is for example made during the start of the lights of the vehicle, when starting the vehicle or when an order dedicated is enabled.

On the other hand, if the outer part 11 does not include a function indicator 39, the pictogram 17 can also fulfill this function. In this case, the backlighting means 19 of the pictogram 17 comprises a first and a second light-emitting diode of different colors, the first being lit only when the function associated with the control of the pictogram 17 is activated, the second being off when the first is on. In the case where the pivot connection between the support 29 and the plate 31 is a hinge connection, the control key 3 also comprises an elastic return means (not shown) of the movable element to its rest position. as for example a torsion spring located at the hinge connection 33 or a compression spring at the end of the support 29 opposite the hinge 33 and placed between the movable member 7 5 and the plate 31. However, in the case where the control means 15 is made by an electric contactor, said electric switch can also serve as an elastic return means. It is obvious that in the case where the pivot connection between the support 29 and the plate 31 is a mounting connection, the support of the user causes the bending of the support and it is the support 29 itself that plays the role of elastic return means returning to its rest position when the user releases the outer portion 11 of the control key 3. FIG. 2 represents a second embodiment of the mobile element 7 in which the The support 29 is made of material with the light guide 27 so that the movable member 7 is made in one piece which can be made of polycarbonate or polymethylmethacrylate. In this case, the whole of the mobile element 7 is transparent or translucent and in particular the portion 21. However, in order to improve the illumination of the pictogram 17, the portion 21 of the mobile element 7 facing the pictogram 17 may form a lens 23 which enables the light from the backlighting means 19 to focus on the pictogram 17. In addition, it should be noted that the embodiment of the movable element 7 is made of a single piece shown on FIG. FIG. 2 can be combined with the embodiment of the pivot link in the form of a hinge link shown in FIG. 1, and conversely the embodiment of the movable element shown in FIG. 1 can be combined with the embodiment of the embedding type connection shown in FIG. 2. FIG. 3 shows an embodiment of a control device 1 comprising five control keys 3 arranged contiguously. The plate 31 is made by a wafer which is supplied with electrical energy and on which is fixed on the one hand the active elements which must be powered such as the backlighting means 19 and 25 of the pictogram 17 and the function indicator 39 and the control means 15 and secondly the passive elements as the movable member 7 at the hinge connection 33. The facade 5 can also be fixed, for example by clipping or gluing, on the platinum 31 or alternatively, the plate 31 can be fixed on the front 5 which then supports the assembly consisting of the control keys 3 and the plate 31. The hinge connection 33 can be achieved by an axial rod, such as a rod metal which is introduced into aligned openings of the movable member 7 and the plate 31. However, in order to reduce the material costs and facilitate the mounting of the control keys 3, the connection hinge 33 is made by a combination between one or more grooves 35 of concave shape at the plate 31 and one or more convex elements 37 formed in the support 29 at the pivot end 30. The convex elements 37 being complementary concave grooves 35. The concave grooves 35 and the convex elements 37 have for example a semi-circle shape with substantially identical diameters, the diameter of the concave groove 35 being slightly greater than that of the convex element 37. The convex elements 37 are placed on the face opposite to the control panel 5, that is to say the face facing the plate 31 on which are positioned the grooves 35. In the embodiment shown in FIG. the movable element 7 comprises two convex elements 37 positioned laterally on one side and the other of the movable element 7. However, one embodiment comprises A single convex element 37 on a portion or the entire width of the movable member 7 is also possible. Thus, the convex elements 37 come to rest and fit into the concave portions 35 to guide the movable member 7 in rotation or pivoting. Furthermore, the movable member 7 is held in position against the plate 31 at the hinge connection 33 due to the presence of the facade 5 which prevents the displacement of the movable member 7 in translation to prevent the detachment of the mobile part 7 of the plate 31 at the hinge connection 33 while leaving enough freedom for the pivotal movement along the axis of rotation of the hinge connection 33. Furthermore, the elastic return means can be achieved by a plate 41 of the movable element 7 which will be bending stress against the plate 31 during the support of the user on the outer portion 11 and which will cause the return to the rest position of the movable member 7 when the user will release his support.

The structure of the control keys 3 shown in FIG. 3 thus makes it possible to easily mount the mobile element 7 on the plate 31 comprising the backlighting means 19 and 25, which makes it possible to reduce the labor required for mounting. - Of the control device 1. Moreover, in the embodiment shown in Figure 3, the width of the surface of the outer portion 11 of the movable member 7 is reduced, that is to say less than one. centimeter for example. However, the outer portion 11 has an elongated shape so that the length of the surface of the outer portion 11 is larger, for example two centimeters or more. Thus, the user can press a control key 3 without the risk of unintentional support on another control key 3 contiguous or adjacent. The use of a pivot connection thus makes it possible to dispense with a guide pin and makes it possible to deport the mechanical guidance of the control keys 3 so that the control keys 3 have a reduced size and can be arranged contiguously. 3 In operation, the user detects the function associated with each control key 3 by means of the pictogram 17 located near the control key 3, for example just above it. , said pictogram 17 being illuminated especially in night driving. When the user wants to activate a function, he just press the outer part 11 of the corresponding control key 3. The support on the outer part 11 causes the movable element 7 to pivot towards the control position and actuates the control means 15. The control means 15 then sends a signal on the one hand to the organ setting the function associated with the control key 3, such as, for example, the defrosting system of the rear window and, secondly, towards the backlighting means 25 which is then activated. The function indicator 39 is then illuminated so that the user knows that the defrosting is activated.

When the user releases the outer portion 11, the flexibility of the support or the elastic return means causes the return of the movable member 7 in the rest position. If the user presses the outer part 11 of the control key 3 again, the defrost is deactivated as is the backlighting means 25, the function indicator 39 is then extinguished.

Thus, when the mounting on the facade 5 is achieved, a facade 5 is obtained from which only the outer portions 11 which have a reduced size project. The outer portions 11 of the various control keys 3 being very close to each other, their alignment provides a visually almost continuous and therefore harmonious and aesthetic. Furthermore, the pictograms 17 representing the functions associated with each control key 3 are positioned in an area adjacent to the outer part 11 of each of the control keys 3, which enables the user to immediately know the function associated with the keys of control 3. Finally, the backlighting of the function indicator 39 and the pictogram 17 allows the user to know respectively the activation status of the functions associated with the pictograms 17 and to locate the control keys 3 associated with the various functions when they are in use. 'night driving.
