Ainsi, le document FR 2 735 610 au nom de la Demanderesse décrit en détail l'utilisation de micro-interrupteurs pour un dispositif de réglage de positionnement d'un siège motorisé et présente les avantages, notamment en termes de modularité et de standardisation, liés à l'utilisation d'un tel micro-interrupteur.Thus, the document FR 2,735,610 in the name of the Applicant describes in detail the use of microswitches for a positioning adjustment device of a motorized seat and has the advantages, in particular in terms of modularity and standardization, related to the use of such a device. microswitch.

On connaît également des interrupteurs comportant une palette de contactage pouvant pivoter entre une première position de repos et une deuxième position active.Also known are switches having a contact paddle pivotable between a first rest position and a second active position.

Dans ces interrupteurs, l'extrémité libre de la palette pivotante est en contact avec une première butée de contactage dans une position de repos et est en contact avec une seconde butée de contactage électrique pour fermer un circuit électrique et ainsi régler par exemple, la position d'un siège.In these switches, the free end of the pivotal pallet is in contact with a first contacting stop in a rest position and is in contact with a second electrical contact stop to close an electrical circuit and thus adjust, for example, the position of a seat.

Certains interrupteurs sont agencés de sorte qu'en appuyant sur la palette de contactage, on emmagasine d'abord une certaine quantité d'énergie de déformation élastique jusqu'au moment où celle-ci provoque un basculement brusque et rapide du basculeur.Some switches are arranged so that pressing the contact palette, it stores first a certain amount of elastic deformation energy until it causes a sudden and rapid tilting of the rocker.

Cet agencement permet à l'utilisateur d'obtenir une sensation tactile spécifique en retour de la commande demandée.This arrangement allows the user to obtain a specific tactile sensation in return for the requested command.

Le but de la présente invention est de proposer un dispositif de commande électrique à retour haptique garantissant une durée de fonctionnement optimale.The object of the present invention is to provide a haptic feedback electrical control device ensuring an optimum operating time.

Sur ces figures, les éléments identiques portent les mêmes numéros de référence.In these figures, the identical elements bear the same reference numbers.

La figure 1 illustre un dispositif de commutation 1 selon l'invention prévu pour la commande d'une boîte de vitesse de véhicule automobile.The figure 1 illustrates a switching device 1 according to the invention provided for the control of a motor vehicle gearbox.

D'autres applications sont envisageables pour la commande de divers organes électriques dans un véhicule automobile, par exemple des lève-vitres, des commandes de déplacement de rétroviseurs électriques, ou encore la commande de déplacement / positionnement des sièges motorisés.Other applications are conceivable for the control of various electrical components in a motor vehicle, for example window regulators, electric mirror movement controls, or the movement / positioning control of the motorized seats.

Le dispositif de commutation 1 comporte une palette pivotante 3 de contactage articulée sur un support par l'intermédiaire de l'axe de pivotement 2.The switching device 1 comprises a pivoting pallet 3 of contact articulated on a support by means of the pivot axis 2.

L'extrémité libre de la palette 3 peut pivoter entre une première position de repos (figure 1) et une deuxième position active (non représentée).The free end of the pallet 3 can pivot between a first rest position ( figure 1 ) and a second active position (not shown).

Le dispositif de commutation 1 comporte en outre un dispositif de commande électrique 5 possédant un organe d'actionnement 7 apte à être actionné par la palette 3 et un commutateur 11 apte à établir un contact électrique, actionnable par l'organe d'actionnement 7.The switching device 1 further comprises an electrical control device 5 having an actuating member 7 adapted to be actuated by the pallet 3 and a switch 11 able to establish an electrical contact, actuable by the actuating member 7.

Selon l'invention, l'organe d'actionnement 7 comporte d'une part, un premier 13 et un second bras 15 reliés l'un à l'autre par une articulation 17 en pivotement.According to the invention, the actuating member 7 comprises firstly, a first 13 and a second arm 15 connected to one another by a hinge 17 pivoting.

Le premier bras 13 est fixé de façon pivotante au support 9 par son extrémité 19 opposée à l'articulation 17.The first arm 13 is pivotally attached to the support 9 by its end 19 opposite to the articulation 17.

L'extrémité opposée 21 à l'articulation 17 du deuxième bras 15 est guidée en coulissement (flèche 18) sur le support 9.The opposite end 21 to the articulation 17 of the second arm 15 is slidably guided (arrow 18) on the support 9.

Ainsi, l'organe d'actionnement 7 est mobile entre une position de repos éloignée du commutateur 11 (figure 3) et une position active dans laquelle l'organe d'actionnement 7 est en contact avec le commutateur 11 pour modifier le contact électrique (figure 4).Thus, the actuating member 7 is movable between a rest position remote from the switch 11 ( figure 3 ) and an active position in which the actuating member 7 is in contact with the switch 11 to modify the electrical contact ( figure 4 ).

Comme on peut le voir sur la figure 2, une liaison élastique 24 sollicite l'organe d'actionnement 7 vers la position de repos.As can be seen on the figure 2 an elastic connection 24 urges the actuating member 7 towards the rest position.

Cette liaison élastique 24 est réalisée par deux ressorts 25 et 27 fixés par leurs extrémités respectives au premier bras 13 d'une part et au deuxième bras 15 d'autre part.This elastic connection 24 is made by two springs 25 and 27 fixed at their respective ends to the first arm 13 on the one hand and the second arm 15 on the other hand.

Pour cela, les extrémités 29 et 31 de chaque ressort 25 et 27 forment avantageusement des crochets, retenus par des protubérances associées formées sur les arêtes latérales des deux bras 13 et 15.For this, the ends 29 and 31 of each spring 25 and 27 advantageously form hooks, held by associated protuberances formed on the lateral edges of the two arms 13 and 15.

Par souci de clarté, cette liaison élastique 24 sous forme de ressort n'a pas été représentée sur les figures 1, 3 et 4.For the sake of clarity, this elastic connection 24 in the form of a spring has not been shown on the figures 1 , 3 and 4 .

On précise que les ressorts 25 et 27 sont dimensionnés de manière à ce que le déplacement de l'organe d'actionnement 7 de la position de repos à la position active corresponde à un effort adapté de l'utilisateur.It is specified that the springs 25 and 27 are dimensioned so that the displacement of the actuating member 7 from the rest position to the active position corresponds to a force adapted by the user.

Préférentiellement, comme illustré par la figure 2, les bras 13 et 15 présentent la forme de cadres.Preferably, as illustrated by the figure 2 the arms 13 and 15 are in the form of frames.

Par facilité de fabrication, on prévoit deux bras 13 et 15 de forme identique.For ease of manufacture, two arms 13 and 15 of identical shape are provided.

Au niveau de l'articulation 17, chaque extrémité de cadre 13, 15 comporte une partie cylindrique 16, un disque de positionnement 18 suivi d'un espace libre, l'espace étant adjacent au disque et de même largeur, et une fourche 20.At the hinge 17, each frame end 13, 15 has a cylindrical portion 16, a positioning disk 18 followed by a free space, the space being adjacent to the disk and of the same width, and a fork 20.

Les parties cylindriques 16 et les fourches 20 sont prévues de sorte que les deux cadres 13 et 15 puissent s'articuler en pivotement, la partie cylindrique 16 d'un cadre s'emboîtant avec la fourche 20 correspondante de l'autre cadre.The cylindrical portions 16 and the forks 20 are provided so that the two frames 13 and 15 can articulate pivotally, the cylindrical portion 16 of a frame fitting with the corresponding fork 20 of the other frame.

Les deux disques 18 sont plaqués l'un contre l'autre, sensiblement au milieu des extrémités des cadres 13 et 15 de manière à positionner un cadre par rapport à l'autre, le disque d'un cadre se positionnant au niveau de l'espace libre correspondant de l'autre cadre.The two discs 18 are pressed against each other, substantially in the middle of the ends of the frames 13 and 15 so as to position one frame relative to the other, the disc of a frame being positioned at the level of the corresponding free space of the other frame.

L'extrémité 21 coulissante du deuxième bras 15 possède avantageusement une forme arrondie.The sliding end 21 of the second arm 15 advantageously has a rounded shape.

L'extrémité 19 du premier bras 13 est de préférence encliquetée dans une protubérance 22 du support 9 présentant une forme de pince.The end 19 of the first arm 13 is preferably snapped into a protrusion 22 of the support 9 having a form of clamp.

En outre, le support 9 possède avantageusement au moins une patte de retenue 33 du deuxième bras 15 dans la position de repos.In addition, the support 9 advantageously has at least one retaining tab 33 of the second arm 15 in the rest position.

Pour cela, la patte de retenue 33 présente la forme d'un crochet qui retient l'extrémité 21 du deuxième bras 15 dans sa position de repos à l'encontre de son rappel élastique 25 tout en permettant le coulissement de cette extrémité 21 sur le support 9 vers la position active lorsque l'utilisateur appuie sur l'articulation 17.For this, the retaining tab 33 has the shape of a hook which retains the end 21 of the second arm 15 in its rest position against its elastic return 25 while allowing the sliding of this end 21 on the support 9 to the active position when the user presses the hinge 17.

On peut prévoir aussi que le support 9 comporte une seconde protubérance 23, présentant avantageusement une forme identique à la patte de retenue 33, pour l'agencement d'un dispositif de commande 1 ayant une position de repos dans laquelle l'articulation 17 est plus éloignée du commutateur 11 qu'avec la patte de retenue 33.It can also be provided that the support 9 comprises a second protrusion 23, advantageously having a shape identical to the retaining tab 33, for the arrangement of a control device 1 having a rest position in which the hinge 17 is more away from the switch 11 with the retaining tab 33.

Pour cela, la seconde protubérance 23 est située entre la patte de retenue 33 et le commutateur 11.For this, the second protrusion 23 is located between the retaining tab 33 and the switch 11.

Ainsi, avec la fabrication d'un seul dispositif de commande 1, on peut à l'assemblage, opter pour l'une ou l'autre des deux hauteurs possibles de l'articulation 17 dans sa position de repos.Thus, with the manufacture of a single control device 1, it is possible to assemble, opt for one or other of the two possible heights of the hinge 17 in its rest position.

Les protubérances 22, 23 et 33 sont de préférence réalisées d'une seule pièce par moulage dans le support 9.The protuberances 22, 23 and 33 are preferably made in one piece by molding in the support 9.

On prévoit en outre qu'un contact électrique est établi dans la position de repos et est coupé dans la position active.It is furthermore provided that an electrical contact is established in the rest position and is switched off in the active position.

Par exemple, comme représenté sur les figures 6 et 7, un contact électrique est établi dans la position de repos pour fermer un circuit électrique et est coupé dans la position active pour régler la position de la vitesse.For example, as shown on Figures 6 and 7 an electrical contact is established in the home position to close an electrical circuit and is turned off in the active position to adjust the speed position.

Avantageusement, le contact électrique s'établit avec un circuit électrique situé sur une face 34 du support 9 opposée à celle en vis-à-vis de l'organe d'actionnement 7.Advantageously, the electrical contact is established with an electric circuit located on a face 34 of the support 9 opposite to that vis-à-vis the actuating member 7.

Cette face arrière 34 du support 9 est mieux visible sur la figure 5, dans laquelle le dispositif de commande électrique 1 est retourné.This rear face 34 of the support 9 is better visible on the figure 5 , in which the electrical control device 1 is turned over.

De préférence, le commutateur 11 est formé d'une tige rigide métallique, de préférence en inox et possédant une déformation 35 de commande prolongée par une extrémité de contactage, apte à établir un contact électrique avec l'organe d'actionnement 7.Preferably, the switch 11 is formed of a rigid metal rod, preferably made of stainless steel, and having a prolonged control deformation by a contacting end, capable of establishing an electrical contact with the actuating member 7.

La commutation est réalisée par le contact entre l'extrémité de la tige 11 et un circuit électrique (non représenté) assemblé au support 9.Switching is achieved by the contact between the end of the rod 11 and an electrical circuit (not shown) assembled to the support 9.

Comme représenté sur les figures 6 et 7, la déformation de commande 35 de la tige 11 est préférentiellement en forme de U renversé.As shown on Figures 6 and 7 the control deformation 35 of the rod 11 is preferably in the shape of an inverted U.

Avantageusement, le contact électrique est réalisé par l'actionnement simultané de deux commutateurs 11, électriquement connectés (figure 5).Advantageously, the electrical contact is made by the simultaneous actuation of two electrically connected switches 11 ( figure 5 ).

Les deux contacts simultanés permettent de doubler la fonction de commutation, permettant ainsi d'améliorer la sécurité de commutation du commutateur 1.The two simultaneous contacts make it possible to double the switching function, thus making it possible to improve the switching security of the switch 1.

Avantageusement, c'est l'articulation 17 de l'organe d'actionnement 7 qui est apte à modifier le contact électrique dans la position active, comme visible sur les figures 6 et 7.Advantageously, it is the articulation 17 of the actuating member 7 which is able to modify the electrical contact in the active position, as visible on the Figures 6 and 7 .

Ainsi, en fonctionnement, l'utilisateur souhaitant modifier une commande fait pivoter un actionneur du dispositif de commande 5, comme par exemple la palette pivotante 3.Thus, in operation, the user wishing to modify a command rotates an actuator of the control device 5, such as for example the pivoting pallet 3.

La palette 3 actionne l'organe d'actionnement 7 du dispositif de commande 5, qui modifie le contact électrique.The pallet 3 actuates the actuating member 7 of the control device 5, which modifies the electrical contact.

Le graphique de la figure 8 représente en abscisse, la course de l'organe d'actionnement 7 en millimètre, entre sa position de repos (0mm) et sa position active (supérieure à 1mm), et, en ordonnée la variation de l'énergie en Newton, nécessaire pour modifier le contact électrique.The graph of the figure 8 represents on the abscissa, the stroke of the actuating member 7 in millimeters, between its rest position (0mm) and its active position (greater than 1mm), and, on the ordinate, the variation of the energy in Newton, necessary for modify the electrical contact.

Dans la zone A, l'énergie de déformation élastique est d'abord emmagasinée dans le dispositif de commande 1.In zone A, the elastic deformation energy is first stored in the control device 1.

Par exemple un effort de l'utilisateur de 5 Newton est nécessaire pour déplacer la palette 3 sur une course d'environ 0.6 mmFor example a user effort of 5 Newton is required to move the pallet 3 on a stroke of about 0.6 mm

Puis, dans la zone B, l'énergie de déformation élastique provoque un basculement brusque et rapide de l'organe d'actionnement 7.Then, in zone B, the elastic deformation energy causes a sudden and rapid tilting of the actuating member 7.

Enfin, dans la zone C, l'utilisateur peut régler la commande par le maintien de son appui sur la palette 3.Finally, in zone C, the user can adjust the control by maintaining its support on the pallet 3.

Le basculement brusque et rapide de l'organe d'actionnement 7 est provoqué par le pivotement des deux bras 13 et 15 à l'encontre du rappel élastique 24 et procure à l'utilisateur une sensation tactile d'avalement spécifique l'informant que sa commande est prise en compte.The abrupt and rapid tilting of the actuating member 7 is caused by the pivoting of the two arms 13 and 15 against the elastic return 24 and provides the user with a tactile sensation of specific swallowing informing him that his command is taken into account.

Selon un deuxième mode de réalisation avantageux illustré par les figures 9 et 10, les deux bras 13 et 15 présentent sensiblement une forme de plaque, de préférence de forme identique.According to a second advantageous embodiment illustrated by the Figures 9 and 10 both arms 13 and 15 have substantially a plate shape, preferably of identical shape.

Le dispositif de commande 5 comporte avantageusement une goupille de liaison 37 sur laquelle s'articulent les extrémités des deux bras 13 et 15, ce qui permet d'améliorer la compacité et la robustesse du dispositif de commande 5.The control device 5 advantageously comprises a connecting pin 37 on which the ends of the two arms 13 and 15 articulate, which makes it possible to improve the compactness and robustness of the control device 5.

Pour cela, les extrémités des deux bras 13 et 15 comportent au moins une languette 38, qui s'assemble avec une languette 38 correspondante de l'autre bras pour pincer la goupille 37, à l'articulation 17.For this, the ends of the two arms 13 and 15 comprise at least one tongue 38, which assembles with a corresponding tongue 38 of the other arm to pinch the pin 37, to the articulation 17.

Avantageusement, à l'articulation 17, les deux bras 13 et 15 forment quatre pinces formées par huit languettes 38, soit quatre languettes 38 par bras.Advantageously, at the hinge 17, the two arms 13 and 15 form four clamps formed by eight tongues 38, four tongues 38 per arm.

Chaque languette, de préférence venue de matière avec le bras, est arquée selon le profil cylindrique de la goupille 37. Les languettes 38 adjacentes sont arquées dans des sens opposés et agencées symétriquement aux languettes 38 correspondantes de l'autre bras, pour être aptes à pincer la goupille 37.Each tongue, preferably integral with the arm, is arcuate along the cylindrical profile of the pin 37. The adjacent tabs 38 are arcuate in opposite directions and arranged symmetrically with corresponding tabs 38 of the other arm, to be adapted to pinch pin 37.

Le premier bras 13 est maintenu de façon pivotante au support 9, de préférence par une vis de fixation 39.The first arm 13 is pivotally supported on the support 9, preferably by a fixing screw 39.

L'extrémité 21 opposée à l'articulation 17 du deuxième bras 15 est guidée en coulissement avantageusement par deux pattes de retenue 33, aptes à retenir le deuxième bras 15 dans la position de repos à l'encontre du rappel élastique 24.The end 21 opposite the articulation 17 of the second arm 15 is advantageously slidably guided by two retaining tabs 33, able to retain the second arm 15 in the rest position against the elastic return 24.

Les figures 11 et 12 illustrent le dispositif de commutation 1 comportant le dispositif de commande 5 selon le deuxième mode de réalisation en position de repos (figure 10) et en position active (figure 11).The Figures 11 and 12 illustrate the switching device 1 comprising the control device 5 according to the second embodiment in the rest position ( figure 10 ) and in the active position ( figure 11 ).

On comprend qu'un tel dispositif de commande électrique 5 ayant un organe d'actionnement 7 comportant d'une part, deux bras 13, 15 reliés l'un à l'autre par une articulation 17 en pivotement, le premier bras 13 étant fixé de façon pivotante au support 9 par son extrémité 19 opposée à l'articulation 17 et l'extrémité opposée 21 à l'articulation 17 du deuxième bras 15 étant guidée en coulissement sur le support 9 et d'autre part, une liaison élastique 24 sollicitant l'organe d'actionnement 7 vers la position de repos, permet d'obtenir une commutation à retour haptique à l'utilisateur, fiable et robuste.It is understood that such an electrical control device 5 having an actuating member 7 comprising, on the one hand, two arms 13, 15 connected to each other by a hinge 17 pivoting, the first arm 13 being fixed pivotally to the support 9 by its end 19 opposite to the hinge 17 and the opposite end 21 to the hinge 17 of the second arm 15 being slidably guided on the support 9 and on the other hand, an elastic connection 24 requesting the actuating member 7 to the rest position makes it possible to obtain a haptic feedback switch to the user that is reliable and robust.
