singing the door.

  A lock control assembly of a vehicle door may have various functionalities depending in particular on the type of lock module. Thus, in certain types of lock modules, the operation of the interior handle makes it possible both to unlock and open the door; this function

  is usually called "over ride".

  There are also lock control assemblies for performing a deadlock of the doors. The activation of deadlocking means makes ineffective any action on the inner and outer handles as well as the furrow zipper when it exists. Thus, a superconducted door can not be opened from either the outside or the inside of the vehicle. The invention aims to provide a lock control assembly provided with means providing a "hands-free" function easily adaptable to a conventional lock module, this control assembly allowing, if necessary to provide additional functions, such as the child conviction or the

  superlocking the classic lock module would be lacking.

  For this purpose, the invention relates to a control assembly of a motor vehicle door lock, of the aforementioned type, characterized in that the proximal outer opening control member is movable from its rest position. towards its open position in a race successively comprising a first dead stroke, during which the proximal and distal external opening control members are decoupled and the identification means activated, and a second stroke during which the proximal and distal external opening control members are coupled, the control assembly further comprising first electric actuating means of the inner opening control distal member controlled by the electronic means so as to be activated

  when an authorization to open the door is plunged.

  According to other characteristics of this assembly: the assembly comprises a retractable dead end stop, intended to cooperate with the proximal external opening control member, controlled by an external lock of the opening and by means of second electric actuation means controlled by the electronic means; the end stop of the dead end is also controlled by a zipper of the inner frieze of the opening; - The end of the dead limit stop is réiice the inner fillet zipper by releasable coupling means controlled by third electrical actuating means controlled by the electronic means; The assembly further comprises a proximal inner opening control member displa, connected between positions of rest and opening of the opening, and first and second support members respectively connected to the proximal and distal members for opening the inner opening, cooperating with each other by mutual support to couple the proximal and distal inner opening control members when the proximal inner opening control member is moved from its home position to its open position ; The assembly comprises first means of retraction of the first support member which, when they are activated, prevent coupling of the first and second support members during movement of the proximal inner opening control member from its rest position to its opening position of the opening, these first retraction means preferably forming means of supercondamnation or child locking the sash; the first retraction means are controlled by fourth electric actuation means controlled by the electronic means; - The first retraction means are controlled by mechanical means connected to a child locking control member arranged in the edge of the opening; - The first retraction means are controlled by mechanical means connected to the outer latch; The comp comprises second means for retracting the second support member which, when they are activated, prevent coupling of the first and second support members during movement of the proximal control member. interior opening its rest position to its open position of the opening, these second retraction means preferably forming means for locking the opening; the second retraction means are controlled by fifth electric actuation means controlled by the electronic means

and the inner frieze zipper.

  The invention will be better understood on reading the description which follows,

  given only by way of example and with reference to the drawings in which: - Figures 1 to 3 are schematic views of a control assembly of a motor vehicle door lock according to three embodiments of the invention; invention respectively; FIG. 4 is a detailed view of child-resistant means for adapting to at least one of the embodiments of the set of

  control iliustré on the previous figures.

  FIG. 1 shows a control assembly 10 for a lock of a door forming a motor vehicle door, according to a first embodiment of

embodiment of the invention.

  In the various control unit channels described below, an element is described as "proximal" when it is close to the end of the control chain intended to be actuated by the user and "distal". > 'when he is away

from this end.

  In Figure 1, there is shown a conventional lock module 12 arranged in a manner known per se in a portion of the box door. In the example shown, the lock module 12 is of the type adapted to equip a front door and comprises four distal control members forming levers 14,16,18, 20 carried by a common support module. The four levers respectively form two distal members 14, 16 for controlling the outer and the inner opening of the door, and two distal control elements 18, 20 for external locking and unlocking.

and inside the door.

  The control assembly 10 also comprises two handles 22, 24 articulated on the door so as to be accessible respectively from the outside and the inside of the vehicle, a crank 26 integral in rotation with a conventional lock rotor (no shown) carried by the door so as to be accessible from outside the vehicle, and a frieze zipper 28 carried by the door so as to be accessible from inside the vehicle. The two outer and inner handles 22 respectively form two proximal outer and inner opening control members. The lock crank 26 and the frieze zipper 28 respectively form two proximal external locking / unlocking control members and

inside the door.

  In some control configurations, the outer and inner handles 22 are coupled with the outer and inner opening control levers 14, 16 respectively by means to be described later. The lock crank 26 and the frieze zipper 28 are coupled by conventional linkages 30,32 respectively to the control levers 18,20.

  external and internal condemnation / unlocking.

  The control assembly 10 is controlled by electronic means including a central unit 34, arranged in the vehicle, connected to a

  conventional electronic circuit internal to the lock module 12, by a connector 36.

  The central unit 34 is connected to conventional means 37 for identifying a compliant user communicating by electromagnetic waves (radio waves or infra-red radiation) with an identifying member 38 intended to be worn by this person.

  user. The identifier member 38 is for example in the form of a badge.

  In accordance with a conventional operation, the identification means 37 deliver

  an authorization to open the door when a compliant user is identified.

  The outer opening control handle 22 is movable from a rest position to an open position of the door in a stroke successively comprising a first dead stroke C1, during which the outer opening control handle 22 is uncoupled from the outer opening control lever 14, and a second stroke C2 during which the outer opening control handle 22 is coupled with the outer opening control lever 14 by means of a conventional tringierie 39. Note in Figure 1 that the handle 22 is shown in solid lines in the rest position and in phantom in the two successive positions corresponding to the end of the races C1

and C2.

  The identification means 37 are activated during the first dead stroke C1, for example by a conventional electric switch 40 actuated by the

  movement of the outer opening control handle 22.

  The inner opening control handle 24, movable between the rest and opening positions of the door, is connected to the inner opening control lever 16 by first and second members 42, 44 cooperating with each other by mutual support. . Thus, when the inner opening control wrench 24 is moved from its rest position to its open position, the first support member 42, connected by a conventional linkage 46 to the inner opening control lever 16, cooperates with the second support member 44, connected to the inner opening control handle 24, to couple the latter with the opening control lever

inside 16.

  A first electric actuator 48 is connected to the first support member 42.

  This first actuator 48, forming electrical means for actuating the inner opening control lever 16, is controlled by the central unit 34. When an authorization to open the door leaf is delivered by the identification means 37, the actuator 48 is controlled by the central unit 34 to move the inner opening control lever 16 so as to separate the two support members 42, 44

One of the other.

  To limit the first dead stroke C1, the control assembly 10

  comprises for example a slider forming a stop 50 end of dead stroke.

  This stop 50 is movable between a position of cooperation with the outer opening control handle 22, as shown in solid lines in FIG. 1, and a retracted position of authorization of the second stroke C2, such that

  shown in phantom in this figure 1.

  The latch mechanism 26 and a second electric actuator 52 are connected to the stop 50 by conventional means 54, 56. The crank 26 forms mechanical means for controlling the stop 50 while the second actuator 52 forms electrical means. control of this stop 50 ft. by the unit

central 34.

  The two actuators 48,50 are connected to the central unit 34, for example via

  the connector 36 and the internal electronic circuit to the lock module 12.

  The main aspects of the operation of the control unit 10 according to the first embodiment of the invention will be described below. In this first mode, the lock module 12 is provided with the function "over ride", that is to say that the actuation of the inner opening control handle 24 allows

  both to unlock and open the door.

  Under normal conditions, the operation of the control unit 10 is managed by the central unit 34 in accordance with a "hands-free" type system. The central unit 34 executes instructions for locking or unlocking the door in a manner known per se, as a function of information transmitted by the user identification means 37 or, if appropriate, by a remote control.

worn by the user.

Normal running.

  To execute a door locking instruction, the central unit 34 controls, on the one hand, an electric actuator for locking / unlocking (not shown), conventionally arranged in the lock module 12, so as to make it act on the inner locking control lever 20 in the locking direction, and secondly the second actuator 52 so as to place the stopper 50 in its position limiting the stroke of the outer opening control handle 22 to the first dead race C1. The actuation of this handle 22 by an unauthorized individual has no effect on the outer opening control lever 14. The door is

therefore doomed.

  To carry out a door unlocking instruction, the central unit 34 controls, on the one hand, the electric lock / unlock actuator arranged in the lock module 12 which acts on the inner locking control lever 20 in the direction of the unlocking, and secondly, the second actuator 52 so as to retract the stop 50 in its position allowing the second stroke C2 of the external opening control handle 22 The actuation of this handle 22 by a user until the end of the second race C2 causes the coupling of the handle 22 with the opening control lever

  external 14 and therefore the opening of the door.

  Under normal operating conditions of the control assembly 10, the opening of the door from outside the vehicle is obtained from the

following way.

  We consider the usual case of a door initially condemned. The stop is therefore in the limiting position of the stroke of the opening control handle 22 to the first dead stroke C1. The user, carrying the identifying member 38, grasps the handle 22 and entrains it from its rest position to its open position so as to parrot the stroke C1. This has the effect of actuating the contactor and activating the identification means 37. As soon as an opening authorization is issued, the central unit 34 controls the first actuator 48 so as to actuate the control lever 16. The unlocking and opening of the door are then obtained by the <over ride> function. It should be noted that the opening of

  the door is realized without moving the stop 50.

  Under standard operating conditions, each of the user identification and unlocking phases (operation of the inner opening control lever 16) generally does not exceed 55 ms, so that the time between the initial seizure of the external opening control handle 22 by the user and the unlocking of the door generally does not exceed 110 ms. This avoids in most cases that the user, grasping the handle 22, blocks the latter at the end of the dead stroke C1 (handle 22 resting against the stop 50) before the unlocking of the door, which could have suggested to the user a

  ineffectiveness of its action on the handle 22.

Emergency operation.

  In the event of a failure preventing the central unit 34 from executing a door unlocking instruction (battery failure, vehicle accident, etc.) while the latter is condemned, the user can unlock the door from outside the door. vehicle by operating the lock crank 26 by means of a key. This has the effect, on the one hand, to actuate the external locking / unlocking control lever 18, and on the other hand, to place the stopper 50 in its retracted position for authorization of the second stroke C2. The door is then decondamnce. The user can also unlock the door from the inside of the vehicle by actuating the frieze zipper 28 or the interior opening control wrench 24, the unlocking of the door being

  obtained in the latter case by the "over ride" function.

  When the door is decondamnce, its opening is obtained from the outside of the vehicle by actuating the external opening control handle 22

  until the end of the second race C2.

  FIGS. 2 and 3 show a control assembly 10 for a lock of a motor vehicle door, respectively according to second and second

  third embodiments of the invention.

  In these figures, elements similar to those of FIG.

by identical references.

  The control assembly 10 according to the second embodiment of the invention (FIG. 2) comprises first means 58 for retracting the first support member 42 which, when they are activated, prevent coupling of the first and second support members 42, 44 when moving the control handle

  interior opening 24 from its rest position to its open position of the door.

  The first retraction means 58 are controlled by third electrical means preferably comprising a third electric actuator 60. The latter, connected to the central unit 34 for example via the connector 36 and the circuit

  electronic internal lock module 12, is controlled by this central unit 34.

  The first retraction means 58 are also controlled by the lock crank 26 to which they are connected by conventional mechanical means

such as a Bowden cable 62.

  The first retraction means 58 advantageously make it possible

  the central unit 34 to carry out superconditional instructions of the po rte.

  To do this, the central unit 34 controls: - the electric actuator locking / unlocking arranged in the lock module 12 so as to act on the inner locking control lever 20 in the direction of conviction, - the second actuator 52 so as to place the stopper 50 in its position limiting the stroke of the outer opening control handle 22 to the first dead stroke C1, and - the third actuator 60 so as to activate the first means

retraction 58.

  Actuation of the outer and inner opening control handles 22,24 by an unauthorized individual has no effect on the outer and inner opening control levers 14, 16. In addition, any action on the frieze zipper 28

  do not change this situation. The door is supercondamnée.

  In the event of a failure preventing the central unit 34 from executing an instruction of uninclosing the door (battery failure, damaged vehicle, etc.) while this is superconducted, the user can desupercondamner the door since

  the outside of the vehicle in action the crank lock 26 by means of a key.

  This has the effect of: actuating the control lever for locking and unlocking the exterior t 8, placing the stopper 50 in its retracted position of authorization of the second stroke C2, and deactivating the first means 58 for retracting the first organ

42.

  The door is then unlocked.

  The control assembly 10 according to the second embodiment of the invention is easily adaptable to a rear door for which there is generally no external lock. In this case, the lock crank is removed, but the lock module 12 as illustrated in FIGS. 1 and 2 can still be used, the external locking and unlocking lever 18 then being decommissioned. The first retraction means 58 can then form child locking means controlled by the third actuator 60 and / or, to remedy and / or escape any failures of the central unit 34, by conventional machanical means 64 controlled in a known manner by by a button 66

  arranged in the edge of the door (see Figure 4).

  The control assembly 10 according to the third embodiment of i. The invention (Figure 3) takes over the functions of that according to the second embodiment. However, in this third embodiment, the lock module 12 is devoid of the <over ride >> function and the levers 18,20 of

  condemnation and external and internal release are decommissioned.

  The door locking function is therefore not performed by the lock module 12 but by second means 68 for retracting the second support member 44. These second retraction means 68, when they are activated, prevent the coupling of the first and second support members 42, 44 during the movement of the inner opening control handle 24 from its rest position to its position

opening of the door.

  The second retraction means 68 are controlled by fourth electrical means preferably comprising a fourth electric actuator 70. The latter, connected to the central unit 34, for example via the connector 36 and the circuit

  electronic internal lock module 12, is controlled by this central unit 34.

  The second retraction means 68 are also controlled by the

  frieze zipper 28 to which they are connected by conventional mechanical means 72.

  The frieze puller 28 also controls the limit stop 50 of dead end. Indeed, the latter is connected to the frieze zipper 28 by releasable coupling means 74 controlled by fifth electric actuation means preferably comprising a fifth actuator 76. The latter, connected to the central unit 34 for example via the connector 36 and the internal electronic circuit to the module of

  lock 12, is controlled by this central unit 34.

Normal running.

  To execute a door locking instruction, the central unit 34 controls, on the one hand, the fourth actuator 70 so as to activate the second retraction means 68 which has the particular effect of placing the frieze zipper in a conditional position, and secondly, the second neutral action 52 so as to move the stopper 50 in its position limiting the stroke of the outer opening control handle 22 to the first dead stroke C1. The actuation of this handle 22 by an unauthorized individual has no effect on the control lever

  14. The door is therefore condemned.

  In order to carry out an unlocking instruction for the door, the central unit 34 controls, on the one hand, the fourth actuator 70 so as to deactivate the second retraction means 68, which notably has the effect of placing the frieze zipper in a unlocking position, and secondly, the second actuator 52 so as to retract the stop 50 in its position allowing the second stroke C2 of the outer opening control handle 22. The actuation of this handle 22 by a user until the end of the second stroke C2 causes the coupling of the handle 22 with the outer opening control lever 14 and therefore the opening of

the door.

  To carry out an instruction of superlocking of the door, the central unit 34 controls: - the fifth actuator 76 so as to disengage the means 74 of coupling of the frieze zipper 28 with the end stop 50 of dead end; the second actuator 52 so as to place the stopper 50 in its position limiting the stroke of the outer opening control handle 22 to the first dead stroke C1, the third actuator 60 so as to activate the first retraction means 58, and the fourth actuator 70 so as to deactivate the second retraction means 68, which notably has the effect of placing the pull tab

  curly in a position of unlocking.

  Actuation of the outer and inner opening control handles 22,24 by an unauthorized individual has no effect on the outer and inner opening control levers 14, 16. In addition, any action on the frieze zipper 28

  do not change this situation. The door is supercondamnée.

  Under the normal operating conditions of the control assembly 10, the opening of the door from outside the vehicle is obtained mutatis mutandis in a manner similar to that described for the first embodiment of the invention. invention, the central unit 34 controlling if necessary the third, fourth eVou fifth actuators 60, 70, 76 so as to unconclude or desupercondamner the

  door, when an opening authorization is issued by the identification means 37.

Emergency operation.

  This is analogous to the emergency operation described for the first

  embodiment of the invention.

  Among the advantages of the invention, it will be noted that the lock control assembly according to this invention comprises means ensuring a "hands free" function easily adaptable to a conventional lock module. In addition, this control assembly makes it possible, if necessary, to provide additional functions, such as the child lock or the deadlock, including the lock module.
