Description

Dispositif antivol pour colonne de direction de véhicule à fonction de sécurité par enfoncement  Antitheft device for vehicle steering column with safety function by depression
L'invention concerne les dispositifs antivol pour colonne de direction de véhicule.  The invention relates to antitheft devices for vehicle steering column.
On connaît de tels dispositifs comprenant un verrou et un mécanisme à pêne. Such devices are known comprising a latch and a bolt mechanism.
Lorsque le véhicule est à l'arrêt, une rotation du volant de direction entraîne le déploiement du pêne suivant une direction non parallèle à l'axe de la colonne de sorte qu'il vient en prise avec cette dernière et empêche toute manœuvre du volant. Lorsque l'utilisateur introduit la clé de contact dans le verrou, le mécanisme rétracte le pêne pour déverrouiller la colonne et libérer le volant. When the vehicle is stationary, a rotation of the steering wheel causes the deployment of the bolt in a direction not parallel to the axis of the column so that it comes into engagement with the latter and prevents any maneuvering of the steering wheel. When the user enters the ignition key into the lock, the mechanism retracts the bolt to unlock the column and release the steering wheel.
Dans une version perfectionnée de ce dispositif, lorsque le véhicule est en marche, la clé ne peut pas être extraite du verrou par un simple mouvement de rotation de la clé et du rotor dans le stator du verrou. Il est nécessaire d'enfoncer préalablement la clé dans le verrou pour pouvoir ensuite l'en extraire. On prévient ainsi toute extraction intempestive ou malveillante de la clé, notamment en raison du danger que l'extraction de la clé représenterait lorsque le véhicule est en marche. En particulier, on évite qu'un enfant transporté sur un siège avant du véhicule puisse saisir la clé pendant le transport.  In an improved version of this device, when the vehicle is running, the key can not be extracted from the latch by a simple rotational movement of the key and the rotor in the latch stator. It is necessary to insert the key beforehand into the lock before being able to extract it. This prevents any inadvertent or malicious extraction of the key, especially because of the danger that the extraction of the key would represent when the vehicle is running. In particular, it is avoided that a child transported to a front seat of the vehicle can seize the key during transport.
Néanmoins, les mécanismes prévus à ce jour pour obtenir les fonctionnalités précitées sont relativement compliqués à assembler et coûteux.  Nevertheless, the mechanisms provided to date to obtain the aforementioned functionalities are relatively complicated to assemble and expensive.
Un but de l'invention est de fournir un mécanisme plus simple à assembler et moins coûteux pour l'obtention de ces fonctionnalités.  An object of the invention is to provide a simpler mechanism to assemble and less expensive to obtain these features.
A cet effet, on prévoit selon l'invention un dispositif antivol pour colonne de direction de véhicule, qui comprend un verrou comportant un rotor et un stator parmi lesquels l'un porte un pion et l'autre présente une gorge de réception du pion conformée de sorte que, à partir d'une position angulaire prédéterminée, une rotation du rotor par rapport au stator dans un sens prédéterminé nécessite un enfoncement préalable du rotor par rapport au stator en direction de l'intérieur du dispositif.  For this purpose, there is provided according to the invention a antitheft device for a vehicle steering column, which comprises a lock comprising a rotor and a stator among which one carries a pin and the other has a shaped pin receiving groove so that, from a predetermined angular position, a rotation of the rotor relative to the stator in a predetermined direction requires a prior depression of the rotor relative to the stator towards the interior of the device.
Ainsi, le pion réalise un indexage de la position relative du rotor dans le stator en rotation et en coulissement. Lorsque le véhicule est en marche, c'est la coopération du pion avec la gorge qui interdit le retrait de la clé sans préalablement enfoncer le rotor dans le stator. Le pion peut être porté par le rotor ou par le stator selon les modes de réalisation.  Thus, the pin performs indexing of the relative position of the rotor in the stator in rotation and sliding. When the vehicle is running, it is the cooperation of the pin with the groove that prohibits removal of the key without first driving the rotor into the stator. The pin may be carried by the rotor or the stator according to the embodiments.
Avantageusement, la gorge présente une face de butée pour le pion, radiale à un axe de rotation du rotor et déterminant la position angulaire.  Advantageously, the groove has an abutment face for the pin, radial to an axis of rotation of the rotor and determining the angular position.
De préférence, la position étant dite de marche et le sens dit d'arrêt, la gorge est conformée de sorte qu'il est possible, sans enfoncer préalablement le rotor, de le faire tourner dans un sens contraire au sens d'arrêt pour atteindre la position de marche. Preferably, the position being said to walk and the meaning of said stop, the throat is shaped so that it is possible, without pressing the rotor beforehand, to turn it in a direction opposite to the direction of stop to reach the running position.
Ainsi, en dépit du fait qu'il faille préalablement enfoncer le rotor dans le stator pour quitter la position de marche, il est facile d'atteindre cette dernière à partir de la position d'arrêt du véhicule dans la mesure où il n'est pas nécessaire de commander une étape d'enfoncement préalable.  Thus, in spite of the fact that the rotor must first be pushed into the stator in order to leave the running position, it is easy to reach the latter from the stopping position of the vehicle insofar as it is not no need to order a prior driving step.
De préférence, le dispositif est agencé de sorte qu'une action sur le rotor pour le faire tourner dans un sens contraire au sens d'arrêt suffit pour le placer dans la position de marche.  Preferably, the device is arranged so that an action on the rotor to rotate it in a direction opposite to the stop direction is sufficient to place it in the running position.
Ainsi, l'utilisateur commande seulement la rotation du rotor. La gorge coopère avec le pion pour faire coulisser le rotor dans le stator au moment opportun durant le mouvement du rotor. La manœuvre du verrou demeure donc simple pour l'utilisateur en dépit du fait que le rotor se déplace avec différents types de mouvements lorsqu'il parcourt sa trajectoire.  Thus, the user only controls the rotation of the rotor. The groove cooperates with the pin to slide the rotor into the stator at the appropriate time during the movement of the rotor. The operation of the lock therefore remains simple for the user despite the fact that the rotor moves with different types of movements as it travels its path.
Avantageusement, la gorge est conformée de sorte qu'il existe au moins une position angulaire du rotor dans laquelle tout coulissement du rotor dans le stator est impossible.  Advantageously, the groove is shaped so that there is at least one angular position of the rotor in which any sliding of the rotor in the stator is impossible.
De préférence, le dispositif comprend un ressort de rappel sollicitant le rotor dans un sens opposé à l'enfoncement.  Preferably, the device comprises a return spring urging the rotor in a direction opposite to the depression.
On facilite ainsi la manœuvre du verrou.  This facilitates the operation of the lock.
Dans un mode de réalisation, la gorge est ménagée dans une face circonférentielle du rotor ou du stator.  In one embodiment, the groove is formed in a circumferential face of the rotor or stator.
De préférence, le pion est immobilisé par rapport au stator à coulissement parallèlement à un axe de rotation du rotor et à rotation autour de cet axe.  Preferably, the pin is immobilized with respect to the sliding stator parallel to an axis of rotation of the rotor and rotating around this axis.
Avantageusement, le dispositif comprend un châssis, le pion étant en prise avec le châssis en immobilisant rigidement le stator par rapport au châssis.  Advantageously, the device comprises a frame, the pin being engaged with the frame rigidly immobilizing the stator relative to the frame.
Ainsi, le pion assure non seulement la fonction d'indexation précitée mais aussi le positionnement rigide du stator par rapport au châssis du dispositif.  Thus, the pin ensures not only the aforementioned indexing function but also the rigid positioning of the stator relative to the frame of the device.
De préférence, le rotor présente une cavité apte à recevoir le pion dans une position telle que le pion s'étend dans le stator sans dépasser d'une face externe de ce dernier.  Preferably, the rotor has a cavity adapted to receive the pin in a position such that the pin extends into the stator without protruding from an outer face of the latter.
Cette cavité permet la réception temporaire du pion pour le montage du verrou dans le châssis.  This cavity allows the temporary reception of the pin for mounting the lock in the frame.
D'autres caractéristiques et avantages de l'invention apparaîtront encore dans la description suivante d'un mode de réalisation donné à titre d'exemple non limitatif en référence aux dessins annexés sur lesquels : - les figures 1 et 2 sont des vues partielles respectivement en perspective et en coupe axiale d'un mode de réalisation du dispositif de l'invention ; Other features and advantages of the invention will become apparent in the following description of an embodiment given by way of non-limiting example with reference to the accompanying drawings in which: - Figures 1 and 2 are partial views respectively in perspective and in axial section of an embodiment of the device of the invention;

- les figures 5 à 8 présentent chacune d'une part le rotor seul avec le pion et d'autre part le dispositif au cours de quatre étapes respectives de fonctionnement de ce dernier ; et - Figures 5 to 8 each have on the one hand the rotor alone with the pin and on the other hand the device during four respective stages of operation of the latter; and
- la figure 9 est une vue à plus grande échelle du rotor et du pion dans la configuration de la figure 8.  FIG. 9 is a view on a larger scale of the rotor and the pin in the configuration of FIG. 8.
On a illustré aux figures 1 à 4 un dispositif antivol 2 pour colonne de direction de véhicule. Le dispositif comprend un châssis 4 définissant dans le dispositif deux parties distantes l'une de l'autre, à savoir une partie de verrouillage 6 illustrée sur les figures et une partie de blocage 8 illustrée seulement en partie à la figure 1 . La partie de blocage 8 comprend notamment un pêne non illustré monté mobile à coulissement par rapport au châssis de façon à pouvoir occuper deux positions, à savoir une position de blocage et une position de déblocage. Dans la première qui est une position étendue, le pêne vient en prise avec une pièce de la colonne de direction de façon à interdire la rotation de la colonne par rapport à la structure du véhicule. Dans la position de déblocage ou position rétractée, le pêne autorise la rotation de la colonne par rapport à la structure. La direction de coulissement du pêne de l'une à l'autre de ces positions est non parallèle à l'axe de rotation de la colonne. La partie de blocage est d'un type connu en lui-même et ne sera pas décrite ici en détail.  FIGS. 1 to 4 show an antitheft device 2 for a vehicle steering column. The device comprises a frame 4 defining in the device two parts distant from each other, namely a locking portion 6 illustrated in the figures and a blocking portion 8 shown only in part in FIG. The locking portion 8 comprises in particular a not shown bolt mounted to slide relative to the frame so as to occupy two positions, namely a locking position and an unlocking position. In the first which is an extended position, the bolt engages a part of the steering column so as to prohibit the rotation of the column relative to the vehicle structure. In the unlocking position or retracted position, the bolt allows rotation of the column relative to the structure. The sliding direction of the bolt from one of these positions is non-parallel to the axis of rotation of the column. The locking portion is of a type known in itself and will not be described here in detail.
La partie de verrouillage 6 comprend un verrou 10 comprenant un stator 12 et un rotor 14 reçu dans un logement du stator. Le rotor 14 est monté mobile à rotation par rapport au stator autour d'un axe 16 de la partie de verrouillage 6. Il est également monté mobile à coulissement par rapport au stator suivant ce même axe 16. Le rotor est donc monté en liaison pivot glissant par rapport au stator.  The locking portion 6 comprises a latch 10 comprising a stator 12 and a rotor 14 received in a housing of the stator. The rotor 14 is rotatably mounted relative to the stator about an axis 16 of the locking portion 6. It is also slidably mounted relative to the stator along the same axis 16. The rotor is thus mounted in pivot connection sliding relative to the stator.
Le dispositif est agencé de sorte que, lorsque le conducteur actionne le verrou au moyen d'un insert tel qu'une clé 20 prévue à cet effet pour faire démarrer le véhicule, le dispositif fait passer le pêne en position de déblocage s'il ne s'y trouvait pas déjà, de façon à permettre la manœuvre de la colonne.  The device is arranged so that, when the driver actuates the lock by means of an insert such as a key provided for this purpose to start the vehicle, the device passes the bolt unlocked position if it does not was not there already, so as to allow the maneuver of the column.
Le verrou 6 comprend des éléments non illustrés tels que des paillettes montées mobiles à coulissement dans des logements 18 du rotor et du stator. Le rotor présente un logement interne 22 présentant une embouchure axiale externe 23. Lorsque la clé 20 est introduite dans le logement 22 par l'embouchure 23, elle place les éléments mobiles dans une configuration telle qu'ils s'étendent intégralement chacun dans le rotor et autorisent la rotation de ce dernier par rapport au stator. En l'absence de la clé, des ressorts de rappel non illustrés placent les éléments mobiles dans une position où ils s'étendent chacun partiellement dans le rotor et dans le stator, empêchant ainsi tout mouvement relatif de ceux-ci. The lock 6 comprises non-illustrated elements such as flakes movably mounted sliding in housings 18 of the rotor and the stator. The rotor has an internal housing 22 having an external axial mouth 23. When the key 20 is inserted into the housing 22 by the mouth 23, it places the movable elements in a configuration such that they extend integrally each in the rotor and allow the rotation of the latter relative to the stator. In the absence of the key, unillustrated return springs place the movable elements in a position where they each extend partially in the rotor and in the stator, thus preventing any relative movement thereof.
Le stator 12 étant fixé rigidement au châssis 4, dans la suite tout mouvement du rotor désignera un mouvement du rotor par rapport au stator.  The stator 12 being rigidly fixed to the frame 4, in the following movement of the rotor will designate a movement of the rotor relative to the stator.
Le verrou comprend un pion 24 ayant une forme à symétrie de révolution autour d'un axe 26 perpendiculaire et radial à l'axe 16. Le pion 24 présente, en l'espèce, deux tronçons d'extrémité respectivement externe 28 et interne 30 séparés l'un de l'autre par un bourrelet annulaire 32 s'étendant en saillie radiale des deux tronçons. Chacun des tronçons présente une face externe cylindrique.  The lock comprises a peg 24 having a symmetrical shape of revolution about an axis 26 perpendicular and radial to the axis 16. The peg 24 has, in this case, two respectively external outer end 28 and inner end sections 30 one of the other by an annular bead 32 extending radially projecting from the two sections. Each of the sections has a cylindrical outer face.
La face cylindrique du tronçon externe 28 a un plus grand diamètre que celle du tronçon interne 30. Lorsque le dispositif est monté comme illustré à la figure 2, le tronçon externe 28 s'étend dans un orifice radial du châssis 4 en réalisant un accouplement mâle-femelle. Le bourrelet 32 et le tronçon interne 30 s'étendent, quant à eux, dans un logement 34 à symétrie de révolution du stator 12. Le pion 24 réalise donc également un accouplement mâle-femelle avec le stator. Dans certaines positions du stator par rapport au rotor, le pion 24 peut coulisser suivant l'axe 26 par rapport au rotor comme on le verra plus loin. Toutefois, dans toutes les autres positions, ce coulissement est interdit de sorte que le pion maintient le stator 12 rigidement fixé au châssis 4. Le logement 34 est suffisamment long pour autoriser cette mobilité du pion par rapport au stator. Un ressort de compression 36 est prévu qui vient en appui par une extrémité axiale contre un épaulement du logement 34 et par l'autre extrémité contre le bourrelet 32 afin de solliciter en permanence le pion suivant la direction de l'axe 26 et dans un sens opposé à l'axe 16. Sous l'effet de cette sollicitation, le bourrelet 32 vient en appui contre le châssis 4, l'orifice de ce dernier qui accueille le pion ayant un diamètre suffisamment petit pour interdire le passage du bourrelet et la sortie du pion, ce qui maintient le pion dans le stator. Le pion se trouve immobilisé par rapport au stator à coulissement parallèlement à I'axe16 et à rotation autour de cet axe. Le tronçon interne 30 du pion traverse aussi un tronçon interne du logement 34 situé au-delà de l'épaulement.  The cylindrical face of the outer section 28 has a larger diameter than that of the inner section 30. When the device is mounted as shown in Figure 2, the outer section 28 extends in a radial hole of the frame 4 by making a male coupling -female. The bead 32 and the inner portion 30 extend, for their part, in a housing 34 with symmetry of revolution of the stator 12. The pin 24 therefore also carries a male-female coupling with the stator. In certain positions of the stator relative to the rotor, the pin 24 can slide along the axis 26 relative to the rotor as will be seen later. However, in all other positions, this sliding is prohibited so that the pin maintains the stator 12 rigidly fixed to the frame 4. The housing 34 is long enough to allow this mobility of the pin relative to the stator. A compression spring 36 is provided which abuts at one axial end against a shoulder of the housing 34 and at the other end against the bead 32 in order to permanently urge the pin in the direction of the axis 26 and in one direction. opposite the axis 16. Under the effect of this bias, the bead 32 abuts against the frame 4, the orifice of the latter which accommodates the pin having a sufficiently small diameter to prevent the passage of the bead and the exit of the pawn, which keeps the pawn in the stator. The pin is immobilized relative to the stator sliding parallel to the axis 16 and rotated about this axis. The inner portion 30 of the pin also passes through an inner portion of the housing 34 located beyond the shoulder.
La fixation rigide du stator 12 au châssis a été illustrée sur la figure 4. Sur cette même figure, on a illustré un vilebrequin 40 du dispositif qui est monté mobile à rotation par rapport au châssis autour de l'axe 16, toute translation du vilebrequin par rapport au châssis étant interdite. Un ressort de compression 42, illustré à la figure 3, est interposé suivant la direction de l'axe 16 entre le vilebrequin 40 et le rotor 14 pour solliciter ce dernier suivant la direction de l'axe 16 dans un sens tendant à le faire sortir du stator, sens indiqué par la flèche 44. On désigne par sens d'enfoncement le sens opposé qui tend à enfoncer le rotor dans le stator en direction du vilebrequin. The rigid attachment of the stator 12 to the frame has been illustrated in FIG. 4. In this same figure, there is illustrated a crankshaft 40 of the device which is rotatably mounted relative to the frame about the axis 16, any translation of the crankshaft relative to the chassis being prohibited. A compression spring 42, illustrated in Figure 3, is interposed in the direction of the axis 16 between the crankshaft 40 and the rotor 14 to urge the latter in the direction of the axis 16 in a direction tending to bring it out of the stator, direction indicated by the arrow 44. It denotes by direction of depression the opposite direction which tends to drive the rotor in the stator towards the crankshaft.
Le dispositif 2 présente une gorge 46 ménagée en l'espèce dans une face externe circonférentielle cylindrique 48 du rotor 14. La gorge a un profil en « U >> dans un plan radial à l'axe 16, les branches du « U >> formant deux flancs venant en appui axial contre le pion 24. La gorge reçoit le tronçon interne 30. La largeur de la gorge suivant la direction de l'axe 16 excède légèrement le diamètre du tronçon interne 30 de sorte que la position du pion dans la gorge détermine la position du rotor le long de l'axe 16. La gorge présente une forme générale annulaire centrée sur l'axe 16 à l'exception d'une chicane 48. Tant que le pion se situe dans la partie annulaire de la gorge, la position du rotor le long de l'axe reste inchangée. Toutefois, lorsque le pion parcourt la chicane, il force le rotor à coulisser le long de l'axe.  The device 2 has a groove 46 formed in this case in a cylindrical circumferential outer face 48 of the rotor 14. The groove has a profile "U" in a radial plane to the axis 16, the branches of the "U >> forming two flanks bearing axially against the pin 24. The groove receives the inner portion 30. The width of the groove in the direction of the axis 16 slightly exceeds the diameter of the inner portion 30 so that the position of the pin in the groove determines the position of the rotor along the axis 16. The groove has a generally annular shape centered on the axis 16 with the exception of a baffle 48. As long as the pin is in the annular part of the throat , the position of the rotor along the axis remains unchanged. However, as the pawn travels through the baffle, it forces the rotor to slide along the axis.
Nous allons présenter plus en détails la forme de la gorge au cours de la description suivante de l'utilisation du dispositif.  We will present in more detail the shape of the groove during the following description of the use of the device.
On suppose, en référence à la figure 5, que le véhicule est à l'arrêt et que le conducteur introduit la clé 20 dans le rotor pour mettre en marche le véhicule. Le pion 24 se trouve alors en butée suivant la direction circonférentielle contre une extrémité de fin de course de la gorge qui est en l'espèce une extrémité de début de course. Nous prendrons cette position angulaire du rotor comme position de référence à 0° autour de l'axe 16. Le verrou est agencé d'une façon connue en elle-même de sorte que c'est seulement dans cette configuration que la clé peut être introduite dans le verrou ou en être extraite suivant l'axe 16. Dès que le rotor quitte la position à 0 °, l'extraction de la clé hors du verrou est impossible.  It is assumed, with reference to FIG. 5, that the vehicle is stationary and that the driver enters the key 20 into the rotor in order to start the vehicle. The pin 24 is then abutted in the circumferential direction against an end-of-stroke end of the groove which is in this case an end of stroke. We will take this angular position of the rotor as a reference position at 0 ° around the axis 16. The lock is arranged in a manner known in itself so that it is only in this configuration that the key can be introduced. in the lock or be extracted along the axis 16. As soon as the rotor leaves the position at 0 °, extraction of the key out of the lock is impossible.
En référence à la figure 6, le conducteur fait tourner la clé et le rotor par rapport au stator autour de l'axe 16 dans le sens horaire illustré par la flèche 50. Il fait ainsi tourner le rotor sur un angle de 20° par exemple. Le tronçon de gorge parcouru par le pion de la position de la figure 5 à celle de la figure 6 étant un tronçon annulaire, le mouvement du rotor est un strict mouvement de rotation. En d'autres termes, de l'une à l'autre de ces deux positions, tout mouvement de coulissement du rotor le long de l'axe 16 est impossible.  Referring to Figure 6, the driver rotates the key and the rotor relative to the stator about the axis 16 in the clockwise direction illustrated by the arrow 50. It rotates the rotor at an angle of 20 ° for example . The groove section traversed by the pin from the position of FIG. 5 to that of FIG. 6 being an annular section, the movement of the rotor is a strict rotational movement. In other words, from one to the other of these two positions, any sliding movement of the rotor along the axis 16 is impossible.
En référence à la figure 7, on suppose que la rotation de la clé et du rotor se poursuit pour atteindre une position angulaire de 40°. Pour passer de la position de la figure 6 à celle de la figure 7, le pion parcourt le début de la chicane 48. Sur cette portion de la gorge, les flancs 52 de la gorge s'étendent dans un plan non radial à l'axe 16, ces deux flancs étant parallèles l'un à l'autre. On désigne par rampe de levée le tronçon de la gorge délimité par les flancs 52. Le mouvement de rotation du rotor impulsé par le conducteur par l'intermédiaire de la clé entraîne donc en outre par effet de came du pion en appui sur l'un des flancs 52 l'enfoncement du rotor 14 dans le sens opposé à la flèche 44 à rencontre de la force de rappel du ressort 42. Referring to Figure 7, it is assumed that the rotation of the key and the rotor continues to reach an angular position of 40 °. To move from position 6 to that of FIG. 7, the peg passes through the beginning of the baffle 48. On this portion of the groove, the flanks 52 of the groove extend in a non-radial plane to the axis 16, these two flanks being parallel to each other. The term "lifting ramp" designates the section of the groove delimited by the flanks 52. The rotational movement of the rotor impelled by the driver via the key thus also causes the cam member to press against one of the pins. flanks 52 the depression of the rotor 14 in the direction opposite to the arrow 44 against the restoring force of the spring 42.
En référence à la figure 8, on suppose que la rotation du rotor s'est poursuivie pour qu'il atteigne une position à 60°. Pour passer de la position de la figure 7 à celle de la figure 8, le pion parcourt un bref tronçon annulaire de la gorge formant le milieu de la chicane, puis se trouve en regard de la sortie de cette dernière en ayant franchit une face plane 54 de la gorge s'étendant dans un plan radial à l'axe 16. Puisque le flanc de la gorge le plus proche du vilebrequin n'interdit plus l'avancée du rotor sous l'effet du ressort 42, le rotor coulisse dans le sens de la flèche 44. Le passage du rotor de la position de la figure 7 à celle de la figure 8 a donc lieu moyennant un strict mouvement de rotation, puis un strict mouvement de coulissement. Le pion 24 se trouve alors finalement hors de la chicane. Le dispositif est agencé de sorte que cette position du rotor entraîne le démarrage du véhicule. Le conducteur cesse donc tout mouvement sur la clé et le dispositif demeure dans cette position dite de marche sous l'effet du ressort 42.  With reference to FIG. 8, it is assumed that rotor rotation has continued to reach a position at 60 °. To move from the position of Figure 7 to that of Figure 8, the piece travels a short annular section of the throat forming the middle of the baffle, then is opposite the exit of the latter having crossed a flat face 54 of the groove extending in a plane radial to the axis 16. Since the side of the groove closest to the crankshaft no longer prohibits the advance of the rotor under the effect of the spring 42, the rotor slides in the direction of the arrow 44. The passage of the rotor from the position of Figure 7 to that of Figure 8 therefore takes place by means of a strict rotational movement, then a strict sliding movement. The pawn 24 is then finally out of the chicane. The device is arranged so that this position of the rotor causes the vehicle to start. The driver therefore stops all movement on the key and the device remains in this so-called walking position under the effect of the spring 42.
A partir de la position de marche, il est possible de poursuivre la rotation du rotor dans le sens 50 dans la mesure où le pion se trouve à l'entrée d'un autre tronçon annulaire de la gorge. Il s'agit alors d'un strict mouvement de rotation du rotor. En revanche, tout mouvement de rotation du rotor, strict ou pas, dans le sens inverse, est interdit car il est empêché par la mise en butée du pion 24 contre la face 54. Il n'est donc pas possible de faire tourner le rotor de façon volontaire ou involontaire à partir de la position de marche pour lui faire regagner la position d'arrêt et ôter la clé.  From the running position, it is possible to continue the rotation of the rotor in the direction 50 to the extent that the pin is at the entrance of another annular section of the groove. This is a strict rotational movement of the rotor. However, any rotational movement of the rotor, strictly or not, in the opposite direction, is prohibited because it is prevented by the abutment of the pin 24 against the face 54. It is therefore not possible to rotate the rotor voluntarily or involuntarily from the walking position to return to the stop position and remove the key.
Perçu par le conducteur, le passage de la position d'arrêt à la position de marche a requis seulement de faire tourner la clé avec le rotor dans le sens 50. La gorge 46 et le ressort 42 ont provoqué le coulissement du rotor lorsque cela était nécessaire.  Perceived by the driver, the transition from the stop position to the operating position required only to turn the key with the rotor in the direction 50. The groove 46 and the spring 42 caused the rotor to slide when it was necessary.
Pour faire parcourir au rotor le trajet de la position de marche à la position d'arrêt, il est nécessaire de commencer par enfoncer le rotor pour lui donner un strict mouvement de coulissement suivant l'axe 16 afin de faire franchir la face 54 au pion 24. A l'issue de ce strict mouvement de coulissement du rotor, effectué par l'action volontaire du conducteur sur la clé en l'enfonçant dans le verrou, le conducteur fait tourner le rotor dans le sens contraire au sens 50 pour lui faire franchir le fond de la chicane. Il s'agit d'un mouvement de rotation strict. To make the rotor traverse the path from the running position to the stop position, it is necessary to start by pressing the rotor to give it a strict sliding movement along the axis 16 so as to cross the face 54 to the counter 24. At the end of this strict sliding movement of the rotor, performed by the voluntary action of the driver on the key by pushing it into the lock, the driver rotates the rotor in the opposite direction to the direction 50 to make him cross the background of the chicane. This is a strict rotation movement.
Puis, en poursuivant le mouvement de rotation, le pion parcourt le tronçon de la gorge définit par les flancs 52 de sorte que, sous l'effet du ressort de compression 42, le rotor coulisse dans le sens de la flèche 44.  Then, continuing the rotational movement, the peg traverses the section of the groove defined by the flanks 52 so that, under the effect of the compression spring 42, the rotor slides in the direction of the arrow 44.
Enfin, le pion retrouve le tronçon annulaire de sorte que le rotor atteint la position d'arrêt par un strict mouvement de rotation.  Finally, the pin finds the annular section so that the rotor reaches the stop position by a strict rotational movement.
Pour le passage de la position de marche à la position d'arrêt, les manœuvres effectuées par le conducteur sont donc tout d'abord un strict enfoncement du rotor, puis une mise en rotation de ce dernier. Compte tenu de la forme de la gorge et de la présence du ressort 42, cette rotation se combine à un coulissement sur une partie du trajet du pion dans la gorge.  For the passage from the running position to the stop position, the maneuvers performed by the driver are therefore first a strict depression of the rotor, then a rotation of the latter. Given the shape of the groove and the presence of the spring 42, this rotation combines with sliding on part of the path of the pin in the groove.
On peut prévoir que le coulissement du rotor s'effectue sur une course de It can be provided that the sliding of the rotor is carried out on a stroke of
2,6 mm par exemple. 2.6 mm for example.
Dans le présent exemple, sur la plus grande partie de la longueur de la gorge 46, le fond 60 de la gorge est suffisamment haut en direction radiale pour interdire tout mouvement du pion 24 en direction de l'axe 16. Il existe cependant une zone unique 55 de la gorge dans laquelle le fond est plus bas pour permettre d'enfoncer le pion en direction radiale jusqu'à mettre le bourrelet 32 en butée contre le fond du logement 34. Dans le présent exemple, cette zone est contiguë à la face 54 et est accessible par le pion lorsque le rotor est en position de marche.  In the present example, over most of the length of the groove 46, the bottom 60 of the groove is sufficiently high in the radial direction to prohibit any movement of the pin 24 towards the axis 16. There is however a zone single 55 of the groove in which the bottom is lower to allow to push the pin radially until the bead 32 abuts against the bottom of the housing 34. In this example, this area is contiguous to the face 54 and is accessible by the pin when the rotor is in the on position.
Pour assembler le dispositif 2, on introduit le rotor 14 dans le stator 12 à partir de l'extrémité axiale interne 62 de ce dernier opposée à celle contiguë à l'ouverture 23 et on place le rotor dans la position de marche. On place ensuite le ressort 36 et le pion 24 dans le logement 34 jusqu'à le faire pénétrer dans la gorge 46 et la zone 55 à rencontre du ressort 36 de sorte que l'extrémité axiale externe du pion ne dépasse pas de la face cylindrique 48.  To assemble the device 2, the rotor 14 is introduced into the stator 12 from the internal axial end 62 of the latter opposite to that contiguous to the opening 23 and the rotor is placed in the on position. The spring 36 and the pin 24 are then placed in the housing 34 until it enters the groove 46 and the zone 55 meets the spring 36 so that the external axial end of the pin does not protrude from the cylindrical face. 48.
On introduit cet ensemble dans l'extrémité axiale externe du châssis 4. Une fois que le pion arrive en regard de l'orifice du châssis qui lui est destiné, il se déploie radialement sous l'effet du ressort 36. Le rotor, le stator, le pion et le châssis se trouvent alors assemblés.  This assembly is introduced into the outer axial end of the frame 4. Once the pin arrives opposite the orifice of the frame which is intended for it, it is deployed radially under the effect of the spring 36. The rotor, the stator the pawn and the frame are then assembled.
Bien entendu, on pourra apporter à l'invention de nombreuses modifications sans sortir du cadre de celle-ci.  Of course, we can bring to the invention many changes without departing from the scope thereof.
On pourrait prévoir que la gorge est portée par le stator et le pion par le rotor. La gorge pourrait être ménagée sur une face perpendiculaire à l'axe 16 du rotor ou du stator et non sur une face circonférentielle. It could be provided that the groove is carried by the stator and the pin by the rotor. The groove could be formed on a face perpendicular to the axis 16 of the rotor or the stator and not on a circumferential face.
La forme de la gorge pourra aussi être modifiée.  The shape of the throat may also be modified.
