EP3808925B1 - Lock for a door of a motor vehicle - Google Patents

Description

The invention relates to a lock for a motor vehicle door, in particular for a vehicle door such as a door, a tailgate, or a motor vehicle trunk.

A motor vehicle lock is intended to be mounted fixed on a motor vehicle door and typically comprises a bolt intended to be moved, for example by pivoting during closing in one direction around a striker plate fixed to the structure of the motor vehicle in order to ensure the closing of the opening.

The opening of the leaf is permitted by a reverse movement such as a rotation of the bolt in the opposite direction. The rotation in the opposite direction when opening the sash follows the movement of the exterior or interior handle which is connected to the lock by a control means which generally acts on an opening lever in order to make the latter pivot. which in turn releases the bolt via a latch in the desired direction.

In addition to the interior and exterior handles of the opening elements fitted to the vehicle, the authorization to open the lock is also controlled by the vehicle key, either mechanically or electrically by an electrical signal.

The locks generally comprise, in addition to a function or a neutral state of unlocking, several functions or locking states which are the exterior locking which makes it possible to prevent the opening of the lock only from outside the vehicle, the interior locking, called "child safety", which prevents the lock from being opened only from inside the vehicle, and the so-called "deadlocking" function, which prevents the lock from being opened both from inside and from outside.

For example, there are double-acting or triple-acting door locks in the state of the art. A double-acting lock has in particular a locking effect and an unlocking effect, which is connected to a control unit via three conductors, two of which are used for power transfer and one for information transfer. The so-called triple effect door locks have two locking states, a first "condemnation" state in which the door is locked and a second "deadlocking" state which corresponds to a locking mode in which the lock is unpickable and can only be unlocked electrically.

In the openings of certain vehicles such as heavy goods vehicles or trucks, an additional function exists to protect the inviolability of users. Indeed, when a driver sleeps in his cabin, it happens that an attempt at inviolability takes place by aggression, for example, of the exterior lock, of the interior handle via the window seal, or other.

To mitigate these aggressions, and protect the driver as well as the contents of the cabin, or even the trailer, the manufacturers add additional security by using an interface which makes it possible to lock the door, independently of the lock.

These additional interfaces block the door when opened. They are completely independent of the main door lock and are activated mechanically.

These additional solutions require a particular interface on the door that is completely independent of the door lock. These interfaces can be activated without locking the lock, for example. This type of interface is known from the application DE102013001951 . These solutions are nevertheless intrusive in the cabin environment.

The documents FR2614643 , JP2001349115 and EP1247928 disclose electrical inhibiting mechanisms configured to inhibit all control means of the primary mechanism.

The invention aims to solve all or part of these drawbacks by proposing a lock for a motor vehicle door which is simple and reliable, and by using a mechanism which is integrated into the lock while making it possible to protect and secure the user from external mechanical or electrical attacks.

The invention also aims to provide a solution which is not intrusive, which coexists with the functions of the lock in an activation cycle and which is scalable up to centralized activation.

• une pluralité de mécanismes secondaires connectés chacun au mécanisme principal pour le commander,
• une pluralité d'interfaces utilisateur, chacune étant connectée à l'un des mécanismes secondaires, configurées pour être actionnées par un utilisateur et permettant l'activation des mécanismes secondaires,

la serrure comprenant un mécanisme d'inhibition configuré pour inhiber tous les moyens de commande du mécanisme principal et/ou secondaires, à partir d'au moins un moyen d'activation et de désactivation formant une commande distincte du mécanisme d'inhibition, le mécanisme d'inhibition étant configuré de telle sorte qu'une désactivation mécanique du mécanisme d'inhibition empêche l'ouverture de l'ouvrant par l'extérieur du véhicule automobile.To this end, the subject of the invention is a lock for a motor vehicle door comprising a main mechanism for controlling a bolt, said bolt being movable between an open position and a closed position in which the bolt is configured to cooperate with a striker. , the lock comprising control means for controlling the main mechanism which comprises the bolt, the control means comprising:

• a plurality of secondary mechanisms each connected to the main mechanism to control it,
• a plurality of user interfaces, each being connected to one of the secondary mechanisms, configured to be operated by a user and allowing the activation of the secondary mechanisms,

the lock comprising an inhibition mechanism configured to inhibit all the control means of the main and/or secondary mechanism, from at least one activation and deactivation means forming a separate control of the inhibition mechanism, the mechanism inhibition being configured such that a mechanical deactivation of the inhibition mechanism prevents the opening of the opening from the outside of the motor vehicle.

Thanks to the combination of these characteristics, a user has a centralized activation and deactivation means for inhibiting, from this said command, all the vehicle lock control means. This command is distinct in particular from the user interfaces connected to the secondary mechanisms.

The secondary mechanism controls the main mechanism. The user interfaces (In) make it possible to act on the secondary mechanisms to authorize them to control the main mechanism to release the bolt and open the lock.

In this way, and thanks to the combination of the characteristics of the present invention, a person who wishes to open the vehicle manually by manipulating the interior or exterior handle, or to lock/unlock the lock electrically from a signal emitted via an electrical or mechanical harness from the interface coming from the key, could in no case enter the vehicle without intervening on the activation and deactivation means, the latter being quite distinct from the control means of the main mechanism . In other words, the actuation of any of the known user interfaces on the vehicle (handle, key in particular) has no effect on the main mechanism. This inhibition controlled by the inhibition mechanism can act either directly on the secondary mechanisms, and therefore indirectly on the main mechanism, or directly on the main mechanism, or even directly on some or all of the secondary mechanisms and on the main mechanism. In general, inhibition makes it possible to render ineffective all the actions performed on the user interfaces dedicated to these mechanisms.

According to an advantageous characteristic, the means for activating and deactivating the inhibition mechanism are configured to be located in the interior space of the vehicle, such as in the passenger compartment of the vehicle.

Advantageously, the deactivation means are mechanical, and the activation means are mechanical or electrical.

Advantageously again, the activation and deactivation means comprise at least one cable or linkage connected to a mechanical interface, the mechanical interface being in translation such as a button or in rotation such as a lever. Such a mechanism is reliable, simple, compact and inexpensive.

According to a particular characteristic, the activation and deactivation means have a mechanical interface located directly on an outer surface of the lock.

It is necessary to understand by outer surface, the surface of the lock oriented towards the passenger compartment of the motor vehicle, offering its accessibility to the user.

The fact that the activation and deactivation means have a mechanical interface on the outer surface of the lock allows a user to have access to and control these activation and deactivation means from the passenger compartment of the vehicle.

According to another particular technical characteristic, the lock is configured to be locked by the inhibition mechanism only if the opening of the vehicle is in a closed position.

• un pêne mobile entre une position d'emprisonnement d'une gâche et une position de libération d'une gâche,
• un cliquet mobile entre une position de blocage de sorte à retenir ledit pêne en position d'emprisonnement de gâche et une position escamotée dans laquelle le pêne est libre en rotation autour de son axe,

la serrure comprenant en outre un mécanisme de condamnation et/ou de supercondamnation configuré pour inhiber un cliquet du mécanisme principal.According to a particular technical configuration, the lock comprises:

• a movable bolt between a locking position of a striker and a release position of a striker,
• a pawl movable between a blocking position so as to retain said bolt in the striker trapping position and a retracted position in which the bolt is free to rotate about its axis,

the lock further comprising a locking and/or deadlocking mechanism configured to inhibit a pawl of the main mechanism.

In such a configuration, the inhibition mechanism is preferably configured to inhibit the unlocking and/or deadlocking mechanism(s) in addition to all the control means of the main mechanism, from the activation and deactivation means , concurrently.

According to another characteristic, the activation of the activation and deactivation means requires the lock to be condemned.

According to yet another characteristic, the activation of the activation and deactivation means is carried out simultaneously with locking and/or deadlocking.

• au moins une des interfaces utilisateurs comprend une clé du véhicule, et
• au moins un des mécanisme secondaires est configuré pour être activé par ladite clé du véhicule.

According to yet another feature:

• at least one of the user interfaces comprises a vehicle key, and
• at least one of the secondary mechanisms is configured to be activated by said vehicle key.

The figure 1 represents a vehicle 1 of the truck or heavy goods vehicle type. Such a vehicle generally comprises a tug or tractor carrier 2 incorporating a cabin for the driver of vehicle 1 and designed to pull a trailer or semi-trailer 3.

It should be noted that the present invention can also be applied to vehicles of the VAN type, van cars or motorhomes.

The vehicle 1 comprises in particular openings 4 allowing access to the cabin which generally includes a space to allow the driver to sleep in his vehicle 1. During these periods of rest in particular, there is a need to guarantee the user inviolability of his vehicle 1 so as to ensure both the safety of its user and to avoid the theft of the vehicle 1 and/or the equipment which it transports. This also applies to the openings 4 of the trailer 3 leading to the transported load.

The present invention aims to prevent this type of attack.

A lock 10 of a motor vehicle 1 is intended to be mounted fixed on an opening 4 of a motor vehicle 1 and typically comprises a bolt 11 intended to be moved, for example by pivoting during closing in one direction around a striker plate (not illustrated) fixed to the structure of the motor vehicle 1 in order to ensure the closure of the opening 4.

The opening of the opening 4 is permitted by a reverse movement such as a rotation of the bolt 11 in the opposite direction. The rotation in the opposite direction when opening the sash 4 follows the movement of the exterior or interior handle 5 which is connected to the lock by a control means which generally acts on an opening lever in order to pivot the latter which in turn releases the bolt 11 via a hooking device in the desired direction.

In addition to the interior and exterior handles 5 of the openings fitted to the vehicle 1, the open or closed state of the lock 10 is also controlled by the vehicle key, either mechanically or electrically by an electrical signal to lock or unlock the opening of the vehicle. .

In other words, as schematized on the figure 2 , the opening of an opening 4 allowing access to the vehicle is done by means of a plurality of user interfaces In, in particular the outer handle 5 forming a first interface I1, an inner handle forming a second interface I2, and the vehicle key mechanically and electrically respectively forming a third and a fourth interface I4, I3.

More precisely, the lock 10 comprises a main mechanism 6 configured to move the bolt between an open position and a closed position in which the bolt 11 is itself configured to cooperate with the keeper.

The lock 10 comprises control means 12 for controlling the main mechanism 6, the control means 12 notably comprising these user interfaces I1, I2, I3, I4 as well as secondary mechanisms 7 mechanically connected to the main mechanism 6 to control it. The actuation of one of the interfaces I1, I2, I3, I4 by the user allows the activation of the corresponding secondary mechanism 7 which in turn controls, successively or concomitantly, the main mechanism 6 acting on the bolt 11 .

According to the invention, the lock 10 comprises an inhibition mechanism 13 configured to inhibit all the control means 12 of the main mechanism 6 from an activation and deactivation means 14 forming a separate control of the mechanism of inhibit 13.

In this way, a user has a means of activation and deactivation 14 centralized to inhibit from this said command, all the control means 12 of the lock 10. Thus, a person who would like to open the vehicle 1 manually by manipulating the interior or exterior handle 5, or unlocking electrically from a signal emitted via an electrical harness or mechanically from the interface coming from the key, could in no case enter the vehicle 1 without intervening on the activation and deactivation means 14. In other words, the actuation of any of the known user interfaces In on the vehicle (handle, key in particular) has no effect on the main mechanism 6 when the inhibition mechanism 13 is activated.

The figure 3 and 4 illustrate views of the secondary 7 and main 6 mechanisms of a lock 10 according to one embodiment.

In these figures, the lock 10 comprises a pivoting bolt 11 intended to cooperate with a keeper (not shown). The bolt 11 is thus capable of pivoting around its axis A11 between an angular position of imprisonment of a striker and a release position of the striker.

The bolt 11 preferably has the shape of a fork defining a notch 20 capable of receiving the striker. In the closed position of the lock 10, the bolt 11 is locked in rotation by a pivoting pawl 8, preventing the rotation of the bolt 11. The pawl 8 of the main mechanism 6 is configured to be driven in rotation by a central opening lever 9 The central opening lever 9 is configured to bear on the pawl 8 directly or via a part which is integral with it and able to move said pawl 8 into its retracted angular position.

It should be noted that, in the lock 10 according to the invention, the pawl 8 is preferably associated with a spring-type return means (not shown) to return the pawl 8 to the angular locking position.

In other words, the pawl 8 is capable of pivoting about its axis A8 between an angular locking position in which the pawl 8 is capable of cooperating in abutment with a notch of the bolt 11 so as to retain said bolt 11 in position strike trap and a retracted angular position in which the bolt 11 is free to rotate about its axis A11.

In addition, the bolt 11 is able to rotate around its axis of rotation A11 parallel to an axis of rotation A8 of the pawl 8. The central opening lever 9 is also able to rotate around an axis of rotation A9 parallel to A11 and A8. This makes it possible to improve the compactness of the lock according to the invention.

• la poignée 5 extérieure formant une première interface I1,
• une poignée intérieure (non illustrée) formant une seconde interfaces I2, et
• la clé du véhicule, autorisant mécaniquement et une commande électrique, autorisant électriquement, l'ouverture de l'ouvrant 4, formant respectivement une troisième et une quatrième interface I4, I3.

As described above, the opening of an opening 4 allowing access to the vehicle is done by means of a plurality of user interfaces In, in particular:

• the outer handle 5 forming a first interface I1,
• an interior handle (not shown) forming a second interface I2, and
• the vehicle key, mechanically authorizing and an electrical command, electrically authorizing the opening of the opening 4, respectively forming a third and a fourth interface I4, I3.

The actuation of one of the interfaces I1, I2, I3, I4 by the user allows the activation of the corresponding secondary mechanism 7 which controls in turn or concomitantly the main mechanism 6 acting on the bolt 11.

The actuation of the external handle 5 forming a first interface I1 allows the driving of the secondary mechanism 71 which is associated with it.

More precisely, the first interface I1 comprises the exterior handle of the vehicle 1 associated with the lock 10.

The handle 5 is connected to a transmission cable (not shown) of the Bowden cable or rod type, making it possible to control the secondary mechanism 71. This transmission cable is connected at a first end to the external handle 5 in question and, to a second end, to an opening lever 21 of the exterior handle 5. The opening lever 21 is rotatable around an axis of rotation A21 which is here coaxial with the axis of rotation A9 of the central lever of opening 9.

The secondary mechanism 71 is configured so that the movement of the opening lever 21 controlled by the first interface I1 causes in its movement the central opening lever 9, this when the inhibition mechanism 13 is not activated. that is to say that it is not in a position to inhibit the control means 12 of the main mechanism. This inhibition mechanism 13 will be described in more detail below. Thus the actuation of the first user interface causes the activation of the secondary mechanism 71 itself mechanically connected to the main mechanism 6 to control it and therefore control the bolt 11.

The actuation of the interior handle forming the second interface I2 enables the secondary mechanism 72 associated with it to be driven.

More precisely, the second interface I2 comprises the interior handle (not shown) of the vehicle 1 associated with the lock 10.

The interior handle is connected to a transmission cable 30 of the Bowden cable or rod type, making it possible to control the secondary mechanism 72. This transmission cable 30 is connected at a first end to the associated interior handle and, at a second end, to an opening lever 31 of said interior handle.

This opening lever 31 is configured to drive, by means of a pin 32, an intermediate lever 33 which is configured to drive the central opening lever 9. The opening 31 and intermediate 33 levers are rotatably mounted way coaxial around the same axis of rotation A31.

Thus the actuation of the second user interface I2 causes the activation of the secondary mechanism 72 comprising in particular these levers 31, 33, said secondary mechanism 72 being itself mechanically connected to the main mechanism 6 to control it and therefore to control the bolt 11.

Concerning the third interface I4, the lock comprises a secondary mechanism 74 to which it is connected.

This secondary mechanism 74 includes a driver 40 electrically controlled and comprising a driving toothed wheel 41 and a coaxial driven wheel 42, the wheel toothed drive 41 being able to drive the driven wheel 42 in rotation by means of a drive member formed by their rotation shaft.

The driver 40 is driven in rotation by a motor 43 and endless screw 44 assembly known per se. Motor 43 is capable of rotating the worm in both possible directions of rotation. The rotation of the endless screw 44 is such as to cause the driving toothed wheel 41 to turn. Which wheel 41 is capable of turning the driven wheel 42 which engages a rack 61 of a transfer lever is able to move said transfer lever 60 in translation. This transfer lever 60 is itself able to act on the first secondary mechanism 71 to move the central opening lever 9.

Concerning the fourth interface I3 formed by the barrel configured to receive the stem of the key, the lock comprises a secondary mechanism 73 to which it is connected.

In a manner known per se, a conventional lock comprises on the one hand a fixed body called a stator, mounted integral with the closing mechanism and/or the opening, and on the other hand, a rotor forming a barrel, of generally cylindrical shape, nested in the fixed body and having a housing that can accommodate a key. A set of sequins, moving radially, retains or releases the rotor in rotation with respect to the fixed body. The flakes are moved when a key is inserted into the rotor housing, and the rotor is only released to rotate when the key is compliant. It is then the rotation of the rotor which triggers the unlocking of the closing mechanism.

In this embodiment, the barrel is integral with a drive wheel 51 able to drive the driven wheel 52 in rotation by meshing it, the latter being configured to move the transfer lever 60 by means of a drive 53 secured to the driven wheel 52 and engaged with the transfer lever 60.

According to another embodiment, the connection between the bolt and the lock 10 can be made by a rod or a gimbal.

As mentioned above, the transfer lever 60 is able to act on the first secondary mechanism 71 to move the central opening lever 9.

Each of these mechanisms will be described in more detail with reference to the following figures as well as the inhibition mechanism which acts on it.

The figure 5 , 6 and 7 , illustrate detailed views of the secondary mechanism 7 configured to be actuated by an interior handle I2 of the vehicle 1 and part of the inhibition mechanism 13 acting on this secondary mechanism 7.

The interior handle I2 is connected to a transmission cable 30 of the Bowden cable type making it possible to control the secondary mechanism 72. This transmission cable 30 is connected at a first end to the associated interior handle and, at a second end, to a leg of an opening lever 31 of said interior handle movable in rotation about an axis A31.

This opening lever 31 is configured to drive, by means of a pin 32, an intermediate lever 33 which is configured to drive the central opening lever 9. The intermediate lever 33 is rotatable around an axis of rotation A33, coaxial with the axis A31 of rotation of the opening lever 31.

The pin 31 is engaged at a first part 331 of the intermediate lever 33 and has a second part 332 opposite the first part 331 with respect to the axis of rotation A33, the second part 332 being configured to cooperate with the central opening lever 9 to drive it in rotation and control the main mechanism 6. In particular, the pin passes through a window 333 of the first part 331 of the intermediate lever 33, this window having a substantially rectangular shape extending radially relative to the axis of rotation A33 of said intermediate lever 33 so that the pin is free in translation in this window in this radial direction.

The lock includes an inhibition mechanism 13 configured to inhibit all the control means of the main mechanism 6.

With regard to the control means 12 formed by the second interface I2 and a second secondary mechanism 72, the inhibition mechanism 13 includes an activation and deactivation means 14 of the push button type (not illustrated). This button 14 is connected to a transmission cable 141 of the Bowden cable type making it possible to control the inhibition mechanism 13.

This transmission cable 141 is connected at a first end to the activation and deactivation means 14 and, at a second end, to an inhibition control lever 80 movable in rotation around an axis of rotation A80.

This inhibition control lever 80 is mechanically linked to a disengagement and clutch lever 81 of the secondary mechanism 72 by means of a connecting rod 82. More precisely, the inhibition mechanism 13 allows, during its activation from the activation and deactivation button 14, to disengage the secondary mechanism 72 so as to inhibit this control means {I2, 72}.

The disengagement and clutch lever 81 has an oblong window 810 configured to be traversed by a rotation shaft coaxial with the axis of rotation A31 of the opening lever 31 also coaxial with the axis of rotation A33 of the intermediate lever 33 .

Due to the oblong characteristic of this window 810, the disengagement and clutch lever 81 has both a degree of freedom in rotation around the axis of rotation A31, A33 and a degree of freedom in translation, according to a direction radial to this axis.

The disengagement and clutch lever 81 also has a generally circular groove 811 extending over a bounded angular sector less than 90 degrees, and of the order here of approximately 70 degrees. This groove 811 extends around an axis parallel to the axes A31 and A33, and not necessarily coaxial given the degree of translational mobility of the part guided in the oblong window 810.

This groove 811 is dimensioned so as to be able to guide the pin 32 which passes through it. Thus, the width of the groove, corresponding to the dimension of the groove taken radially relative to the center of its circular shape, corresponds at least locally to the diameter of the pin 32 that it receives.

The opening lever 31 is arranged between, and in particular interposed between the intermediate lever 33 and the disengagement and clutch lever 81.

Pin 32 passing through intermediate lever 33 at its window 333 and disengagement and clutch lever 81 at its groove 811, pin 32 also passes through an opening 311 of opening lever 31.

This opening 311 has, similarly to the groove 811, a generally circular shape extending over a bounded angular sector less than 90 degrees. This opening 311 extends around the axis of rotation A31 forming the center of its circular shape.

This opening 311 forms a path for the pawn along this angular sector around the axis A31 and has a notch 312 formed by a space open radially on the opening 311, the notch 312 being located radially towards the outside of the opening 311 with respect to the axis of rotation A31 and configured to enclose the pin 32 when it is housed there.

Par ailleurs, pour activer le mécanisme d'inhibition 13, l'utilisateur procède comme suit :
• presse le bouton d'activation et de désactivation 14, déplaçant le câble de transmission 141 et entraînant la rotation du levier de commande d'inhibition 80 autour de son axe A80,
• la rotation du levier de commande d'inhibition 80 entraine la translation radiale du levier de débrayage et d'embrayage 81 auquel il est relié par la bielle 82, cette translation étant guidée par la fenêtre oblongue 810,
• La translation radiale du levier de débrayage et d'embrayage 81 entraine le déplacement radial du pion 32 du cran 312 vers l'ouverture 311,
• Une fois dans l'ouverture 311, celle-ci présentant une forme d'une portion circulaire, le pion est libéré de sa contrainte de la rotation du levier d'ouverture 31 ce qui positionne le deuxième mécanisme secondaire dans une position débrayée : la rotation dudit levier d'ouverture 31 dans cette position n'entraine donc plus la rotation du levier intermédiaire 33 et n'a alors plus d'effet sur le mécanisme principal 6, donc sur le pêne 11 : le mécanisme d'inhibition 13 en étant activé par l'utilisateur inhibe ce moyen de commande 12 du mécanisme principal 6.

When the inhibition mechanism 13 is inactive, the control means 12 are operational, i.e. the actuation of the second user interface I2 causes the activation of the secondary mechanism 72, in particular:

• the transmission cable 30 rotates the opening lever 31 around the axis A31,
• the pin, clamped in the notch 312 of the opening lever 31 is moved and causes in its movement the rotation of the intermediate lever 33, the pin also being held in the window 333 of the said intermediate lever,
• the rotation of the intermediate lever 33 causes the rotation of its second part 332 which is configured to cooperate by pressing with the central opening lever 9 to cause it to rotate and control the main mechanism 6. Furthermore, to activate the mechanism inhibit 13, the user proceeds as follows:
• presses the activation and deactivation button 14, moving the transmission cable 141 and causing the rotation of the inhibition control lever 80 around its axis A80,
• the rotation of the inhibition control lever 80 causes the radial translation of the disengagement and clutch lever 81 to which it is connected by the connecting rod 82, this translation being guided by the oblong window 810,
• The radial translation of the disengagement and clutch lever 81 causes the radial displacement of the pin 32 from the notch 312 towards the opening 311,
• Once in the opening 311, the latter having the shape of a circular portion, the pin is released from its constraint of the rotation of the opening lever 31 which positions the second secondary mechanism in a disengaged position: the rotation said opening lever 31 in this position therefore no longer causes the rotation of the intermediate lever 33 and then no longer has any effect on the main mechanism 6, therefore on the bolt 11: the inhibition mechanism 13 being activated by the user inhibits this control means 12 of the main mechanism 6.

Furthermore, it will be noted that the inhibition control lever 80 comprises a protrusion 801 configured to come into contact and bear against a predefined zone of a transfer lever 60 and which, when said inhibition control lever 80 is pivoted, it causes in its travel the transfer lever 60 in translation.

An inhibition protuberance 802 also makes it possible to lock the transfer lever 60 once translated. This protrusion 802 thus ensures a blocking function of the transfer lever 60 after its translation towards the inhibition position by the inhibition mechanism 13.

The figure 8 , 9 and 10 , illustrate detailed views of the secondary mechanism 7 configured to be actuated by an exterior handle 5 of the vehicle 1 and part of the inhibition mechanism 13 acting on this secondary mechanism 7.

The outer handle 5 is connected to a transmission cable (not shown) of the Bowden cable type making it possible to control the first secondary mechanism 71. This transmission cable is connected at a first end to said outer handle 5 and, at a second end, to an opening lever 21 of the exterior handle 5, at a fixing interface 210 of the opening lever.

The opening lever 21 is rotatable around an axis of rotation A21 coaxial with the axis of rotation A9 of the central opening lever 9. The opening lever 21 has the shape of a hook, one end of which moves said central opening lever 9 when the secondary mechanism 71 is activated by the first interface I1.

This movement, or drive of the central opening lever 9 is indirect, that is to say that an intermediate piece is located between the opening lever 21 and the central opening lever 9, in particular interposed between these two levers 9 , 21 during this training. This intermediate part is a clutch and disengagement lever 22 rotatable around an axis of rotation A22, parallel to the axis of rotation A21, even coaxial with the axes A9 and A21 when the inhibition mechanism 13 is inactive. .

• le câble de transmission entraine en rotation le levier d'ouverture 21 autour de l'axe A21,
• le levier d'ouverture 21 entraine dans sa rotation, la rotation du levier d'embrayage et de débrayage 22 dont l'axe de rotation A22, à cette étape, est colinéaire aux axes de rotation A9 et A21,
• le levier d'embrayage et de débrayage 22 entraine en rotation le levier central d'ouverture 9 du mécanisme principal 6 pour commander ledit mécanisme principal 6. Par ailleurs, pour activer le mécanisme d'inhibition 13, l'utilisateur procède comme suit :
• presse le bouton d'activation et de désactivation 14, déplaçant le câble de transmission 141 et entraînant la rotation du levier de commande d'inhibition 80 autour de son axe A80,
• lorsque ledit levier de commande d'inhibition 80 est pivoté, celui-ci entraine dans sa course le levier de transfert 60 en translation par l'intermédiaire de l'excroissance 801 qui est en appui contre le levier de transfert 60,
• le levier de transfert, dans sa translation, emporte la translation du centre de rotation du levier d'embrayage et de débrayage 22 de sorte qu'il se déplace dans une position où il est écarté du chemin du levier d'ouverture 21 inhibant par le même temps ce mécanisme secondaire 71 et donc ce moyen de commande 12 du mécanisme principal 6.

A rotation shaft of the clutch and disengagement lever 22 is mounted in an oblong window 62 of the transfer lever 60 so that, when the transfer lever 60 is moved by the inhibition mechanism 13, the latter drives in its movement the translation of the center of rotation of the clutch and disengagement lever 22 so that it moves into a position (not shown) where it is moved away from the path of the opening lever 21. In this case, the mechanism secondary 71 is in the disengaged position, actuation of the first interface rotates the opening lever 21 of the first secondary mechanism which does not drive the central opening lever 9 of the main mechanism 6. The secondary mechanism 71 does not then has more effect on the main mechanism 6, therefore on the bolt 11: the inhibition mechanism 13, being activated by the user, inhibits this control means 12 of the main mechanism 6. In other words, when the inhibition mechanism 13 is ina ctif, the control means 12 are operational, that is to say that the actuation of the first user interface I1 causes the activation of the associated first secondary mechanism 71, in particular:

• the transmission cable rotates the opening lever 21 around the axis A21,
• the opening lever 21 causes in its rotation, the rotation of the clutch and disengagement lever 22 whose axis of rotation A22, at this stage, is collinear with the axes of rotation A9 and A21,
• the clutch and disengagement lever 22 rotates the central opening lever 9 of the main mechanism 6 to control said main mechanism 6. Furthermore, to activate the inhibition mechanism 13, the user proceeds as follows:
• presses the activation and deactivation button 14, moving the transmission cable 141 and causing the rotation of the inhibition control lever 80 around its axis A80,
• when said inhibition control lever 80 is pivoted, the latter drives in its travel the transfer lever 60 in translation via the protrusion 801 which bears against the transfer lever 60,
• the transfer lever, in its translation, carries the translation of the center of rotation of the clutch and disengagement lever 22 so that it moves into a position where it is moved away from the path of the opening lever 21 inhibiting by the same time this secondary mechanism 71 and therefore this control means 12 of the main mechanism 6.

The figure 11 , 12 and 13 , illustrate detailed views of the secondary mechanisms configured to be actuated by a key, either mechanically or electrically by an electrical signal, and a part of the inhibition mechanism 13 acting indirectly on these secondary mechanisms, according to this embodiment.

The key is configured to actuate the secondary mechanisms 73, 74 of the lock 10.

The third secondary mechanism 74 comprises a driver 40 electrically controlled and comprising a driving toothed wheel 41 and a coaxial driven wheel 42, the driving toothed wheel 41 being able to drive the driven wheel 42 in rotation by means of a drive member formed by their common rotating shaft.

The driver 40 is driven in rotation by a motor 43 and endless screw 44 assembly known per se. Motor 43 is capable of rotating the worm in both possible directions of rotation. The rotation of the worm screw 44 is such as to cause the driving toothed wheel 41 to turn. Which wheel 41 is able to turn the driven wheel 42 which engages the rack 61 of the transfer lever to move said transfer lever 60 in translation. This transfer lever 60 is for its part capable of acting on the first secondary mechanism 71 to move the central opening lever 9.

The motor is electrically controlled by the user's key. The key also comes to cooperate mechanically with the fourth interface I3 formed by the barrel configured to receive the stem of the key, the lock comprises a secondary mechanism 73 to which it is connected.

The barrel is integral with a drive wheel 51 able to drive the driven wheel 52 in rotation by meshing it, the latter being configured to move the transfer lever 60 by means of a drive member 53 integral with the driven wheel 52 and in engagement with the transfer lever 60.

As mentioned above, the transfer lever 60 is able to act on the first secondary mechanism 71 to move the central opening lever 9.

As described previously, the inhibition control lever 80 comprises a protrusion 801 driving the transfer lever 60 in its travel in translation when the activation and deactivation means 14 is controlled, and drives the transfer lever in rotation. inhibition control 80 and a protrusion 802 to block said transfer lever 60 after its translation towards the inhibition position by the inhibition mechanism 13.

The blocking of this transfer lever 60 here ensures the inhibition of these third and fourth secondary mechanisms and therefore of the control means 12 of the main mechanism 6 at the level of these interfaces I3 and I4. Indeed, in the locked position of the inhibition mechanism 13, the transfer lever 60 being blocked in translation, the rotation of the motor shaft 43 and the rotation of the barrel have no effect on said transfer lever 60.

The figure 14 , 15 and 16 illustrate detailed views of two activation and deactivation means 14 each forming a separate control of the inhibition mechanism 13, according to this embodiment.

As has been described opposite, the inhibition mechanism 13 comprises an activation and deactivation means 14 of the push button type (not shown), located on the outer surface 15 of the lock 10. This button 14 is connected to a transmission cable 141 of the Bowden cable type making it possible to control the inhibition mechanism 13. This transmission cable 141 is connected at a first end to the activation and deactivation means 14 and, at a second end, to a lever inhibition control 80 movable in rotation about an axis of rotation A80.

A second activation and deactivation means 14' is located at the level of the inhibition control lever 80.

Indeed, it is a rotating pin 142, located on the outer surface 15 of the lock 10, comprising a head 143 having an indentation 144 able to receive the stem of the key so that, when the stem is housed in this cavity 144, the rotation of the key, and therefore of the rod, causes the rotation of the rotary pin 142.

The rotary pin 142 further comprises a transmission member 145 engaged in a housing 146 of the clutch release and clutch lever 81 of the secondary mechanism 72 so that the rotation of the rotary pin 142 causes the rotation of the release lever and clutch 81, this without having to act on the inside handle of the opening.

It should be noted that the second activation and deactivation means 14' can be a pin activated directly by the user's hand.

The presence of two activation and deactivation mechanisms 14 and 14' provides additional security in the event of failure of one of them.

Furthermore, the activation and deactivation means 14, 14' of the inhibition mechanism 13 are located in the interior space of the vehicle, such as in the passenger compartment of the vehicle.

Indeed, in the case of heavy goods vehicles, the user who wants to protect himself from any attack or any attempt to break into the vehicle can be in his cabin in complete safety and control, centrally with one of the means of activation and deactivation 14, 14', inhibition of all vehicle access interfaces.

Such activation and deactivation means 14, 14' are moreover discreet and are not as intrusive as those known from the prior art.

These activation and deactivation means 14, 14' are here mechanical (button connected to a linkage or rotary pin).

Whatever the embodiment chosen, it will be noted that the activation means and the deactivation means can be distinct.

In this case, and to further increase the safety of the user, only the activation means can be electrical, the deactivation means being mechanical, further guaranteeing the inviolability of access to vehicle 1.

The figure 17 and 18 illustrate detailed views of the lock making it possible to understand how, mechanically, the activation of the inhibition mechanism 13 is prohibited when the door of the vehicle 1 is open.

This function prevents the user from being trapped outside his vehicle. Indeed, the pivoting bolt 11 is intended to cooperate with a keeper (not shown). The bolt 11 is thus capable of pivoting around its axis A11 between an angular position of imprisonment of a striker and a release position of the striker.

The bolt 11 comprises a blocking lug 111 configured to come into the path of the transfer lever 60, at the level of a blocking zone 63 of said transfer lever 60, this when the bolt 11 is in the striker release position, at know when the opening is open or able to be opened, thus blocking any translation of the transfer lever 60.

The transfer lever 60 being blocked in this position of the bolt 11, the inhibition 80 and disengagement and clutch 81 control levers actuated by the means activation and deactivation 14, 14' are therefore not operational, thus prohibiting the activation of the inhibition mechanism 13 when the opening is open.

In this way, the lock 10 is thus configured to be locked by the inhibition mechanism 13 only if the opening of the vehicle is in a closed position.

It will be noted that any locking mechanism of the transfer lever 60 or more generally any locking mechanism of the inhibition mechanism 13 depending on the position of the opening can provide an equivalent function.

Thanks to such a lock mechanism 10 and thanks to such an inhibition means, it is therefore possible to carry out the locking of said lock 10 in a centralized manner at the level of a control 14, 14'.

The invention therefore makes it possible, by activating the inhibition mechanism 13, to simultaneously lock (prevent opening from the outside) the lock(s) of the vehicle.

Thus, all the secondary mechanisms 7 connected to each of the interfaces I1, I2, I3 and I4 (see the figure 19 for example) are thus inhibited and are no longer operational when the inhibition mechanism 13 is activated by the user located in the cabin of his vehicle 1.

It will be noted that the inhibition mechanism 13 can be assisted electronically. For example, the lock may have 600 sensors (see the figure 19 and 20 for example) making it possible to ensure the correct position of the parts, in particular of the bolt 11 or of the transfer lever 60 for example.

The figure 21 , 22 , 23 , 24 and 25 illustrate detailed views of part of the inhibition mechanism 13 at the level of its actuation by the activation and deactivation means 14, located on the outer surface 15 of the lock 10, making it possible to illustrate a mechanical memorization function of the inhibition mechanism 13 and an operating sequence (see the Figures 22A, 22B , 22C, 22D, 22E, 22F, 22G, 22H and 22I ), according to one embodiment.

Similarly to what has been described above, the activation and deactivation means 14 causes the rotation of the inhibition control lever 80 around its axis A80, the lever at the same time driving during its rotation the protuberance 801, which moves the transfer lever 60 in translation along an axis substantially perpendicular to the force exerted by the cable 141 on the inhibition control lever 80.

Radially between the axis A80 around which the inhibition control lever 80 pivots and the connection between the transmission cable 141, is located a window 803 substantially oblong inside which comes to cooperate an operating pin 92 of a locking lever 90.

This locking lever is configured to translate along an axis orthogonal to the axis of translation of the transfer lever 60.

A torsion spring 91 is interposed between the blocking lever and the inhibition control lever 80 and makes it possible to exert a constraint on the blocking lever 90 tending to push it towards the transfer lever 60.

As inhibiting control lever 80 is pivoted during actuation of inhibiting mechanism 13, blocking lever 90 is translated towards transfer lever 60 (see Figures 21, 22A, 22B and 22C ) until it comes into contact and abuts against a sliding surface 64 of said transfer lever 60, this being constrained by the spring 91 (see the figures 22D, 22E and 22F ).

This sliding surface 64 is located on a step or a recess 65 so that, still during the rotation of the inhibition control lever 80, the protrusion 801 moves the transfer lever 60 in translation until the lever locking block 90, then in contact and abutting against this sliding surface 64, reaches the limit of this recess 65 (see the figure 22G ) and, once this limit has been reached, it continues its translation in a hollow 66 delimited by this recess 65 to lodge there (see the figures 22H and 22I ). By fitting therein, the blocking lever 90 ensures blocking of the transfer lever 60, preventing it from returning to its initial position after its translation driven by the activation of the inhibition mechanism 13 by the mechanical actuation and user manual button 14.

In the event of an attempt at mechanical unlocking at the level of the key cylinder or by electrical impulse in the motor, the locking lever is then forced between a fixed structure S and the recess 65 of the transfer lever 60 (see the figure 25 ). The inhibition mechanism 13 is further configured so that the reverse rotation of the inhibition control lever 80 towards deactivation does not cause in its travel the reverse translation of the transfer lever 60.

Indeed, the window 803 of the inhibition control lever 80 has a larger dimension than the maneuver pin 92 of the blocking lever 90. Thus, this maneuver pin 92 bears against a drive edge of this window 803 to drive the locking lever 90 in translation, but there is then a clearance J (see the figure 21 ) between said operating pin 92 and an opposite edge of said window 803 to the drive edge so that when the inhibition control lever 80 returns to position, the pin does not bear from the start of its translation against this opposite edge and does not cause the reverse translation of the locking lever 90 during a initial run. Such play makes it possible, in the locking position of the locking lever 90, by direct actuation during a break-in attempt for example, not to cause the reverse rotation of the inhibition control lever 80.

Furthermore, the torsion spring 91 keeps the locking lever 90 locked against the transfer lever 60.

Once the reverse rotation of the inhibition control lever 80 towards an inactivation position, and the play of the window 803 has been covered, the operating pin 92 is then driven by the window 803 and brings back the blocking lever 90 in idle position. However, the reverse rotation of the inhibition control lever 80 causes the protrusion 801 in its rotation which, in this direction of rotation, has no effect on the translation of the transfer lever 60. In this way, the deactivation of the inhibition mechanism 13 leaves the lock condemned since the transfer lever remains in its translated position, the opening remaining disengaged.

The figure 26 illustrates a diagram of the operation of a lock and the associated activation and deactivation means making it possible to understand in particular the activation, the prohibitions and the unlocking or deactivation of the function of the centralized inhibition mechanism.

The states E1, E2, E3, E4 and E5 designate states of the lock at a given moment of operation while the references A1 to A17 correspond to actions by the user on the lock.

Let us consider that a user acts on the lock 10 of the vehicle in an initial state E1 corresponding to a state in which the lock is unlocked, open, that is to say that the bolt of the lock is not retained by the pawl, and the unlocked interior opening (for example an unlocked child lock). In this case, the activation A1 of the inhibition mechanism 13 of the control means 12, like the locking A2 of the lock 10 are not possible given the open state of the lock, it is then necessary to close the lock by an action A3 to change its state to state E2.

This state E2 corresponds to a state in which the lock is unlocked, closed, that is to say that the bolt of the lock is retained by the pawl, and the interior opening unlocked. It is therefore understood that the actions of exterior opening A4 as interior A5 bring the lock back to the state E1 while its locking A6 brings the lock 10 into a new state E3 in which the lock is locked, closed, the interior opening unlocked , a user in the vehicle being able to exit. The activation of the control means 12 of the inhibition mechanism 13 can be performed when the lock is in state E2 or in state E3. These activations A7 and A8 bring the lock into a new successive state E4 in which the lock is locked, closed, the interior opening locked. In this state, all the control means 12 of the main mechanism are then inhibited and no action on one of the control means 12 has any effect on the lock 10. In other words, the actuation A9 of the exterior handle, that of the interior handle A10, the electrical unlocking A11 or the mechanical unlocking A12 with the key cannot change the state of the lock 10.

The only action A13, preferably mechanical on the lock in state E4 consisting in deactivating the inhibition mechanism 13 of the control means 12, for example by a button located in the interior space of the vehicle cabin, makes it possible to modify the state of the lock 10 to a state E5 similar to the state E3 in which the lock 10 is locked, closed, the interior opening unlocked, a user in the vehicle being able to exit.

Once in this state E5, an electrical A14 or mechanical A15 unlocking with the key returns the lock 10 directly to the state E2 while an opening from the inside A17, then unlocked, brings the lock to its initial state E1.

In this same state E5, it will be noted that the lock being in a locked state from the outside, an action A16 tending to open the lock from outside the vehicle will have no effect and will leave the lock in its state E5.

Indeed, the invention allows, by performing a mechanical deactivation of the inhibition mechanism 13, to remain condemned (prevent opening from the outside) since by deactivating the function of the centralized inhibition mechanism, the external opening remains disengaged and pulling the handle, nothing happens.

• de condamner la serrure (empêcher l'ouverture par l'extérieur) via un faisceau électrique par exemple et ensuite d'activer la fonction d'inhibition centralisée du mécanisme d'inhibition 13 pour inhiber tous les moyens de commande 12 ;
• en activant le mécanisme d'inhibition 13, de faire de manière concomitante une condamnation (empêcher l'ouverture par l'extérieur) ;
• en faisant une désactivation mécanique du mécanisme d'inhibition 13, de rester condamné : en effet, en désactivant le mécanisme d'inhibition 13, l'ouverture extérieure reste débrayée et en tirant sur la poignée, il ne se passe rien.

Thanks to the present invention, such a solution allows:

• to condemn the lock (prevent opening from the outside) via an electrical harness for example and then to activate the centralized inhibition function of the inhibition mechanism 13 to inhibit all the control means 12;
• by activating the inhibition mechanism 13, to make a condemnation concomitantly (prevent opening from the outside);
• by performing a mechanical deactivation of the inhibition mechanism 13, to remain condemned: indeed, by deactivating the inhibition mechanism 13, the external opening remains disengaged and by pulling the handle, nothing happens.

The invention is described in the foregoing by way of example. It is understood that a person skilled in the art is able to produce different variant embodiments of the invention without departing from the scope of the invention, as defined in the appended claims.
