Description

The The present invention relates to a locking system for a motor vehicle door comprising a A plurality of spaced-apart positionable closing elements and one of the closing elements spaced common control unit to operate these closing elements. The invention finds particular application in sliding doors of passenger cars.

The The invention relates in particular to the integration of a motor vehicle door locking system into a motor vehicle door or flap and / or in an outer frame the vehicle body in which the vehicle door or flap is used. It is particularly about side doors, preferably sliding doors, rear doors, tailgates, Trunk flaps, roof structures and the like.

at such, possibly very large and heavy, motor vehicle doors must regularly several Door locks or closing units be provided that in the closed and / or in the open Condition the position of the vehicle door with respect to the vehicle safely fix.

It has been found that it is advantageous in such complex door locking systems with a plurality of spatially spaced closing units to control a plurality of closing units of the door closing system from a single control unit. Such a motor vehicle door locking system is for example from the DE 102 33 485 A1 out. A similar system, in which additionally a locking mechanism for a window pane is centrally controlled, goes out of the DE 10 2005 019 607 A1 out.

The known door locking systems However, some are too complicated, so that in particular a big Number of different parts to achieve only a limited functionality of the door closing system is needed. In addition, in known systems also partially electronic Adjusting means for the door closing systems used in terms of manufacturing for such a door closing system and in consequence of an increased susceptibility to higher Can lead to manufacturing and operating costs.

task It is the object of the present invention with reference to the prior art Technique described problems at least partially solved. Especially intended a locking system for one Motor vehicle door are specified in which a control of the various closing elements in a particularly simple, in particular mainly mechanical, Way is realized. It should in particular possible many locking states and / or electrically assisted operations the closing elements allows become.

These Tasks are solved with a locking system according to the characteristics of claim 1. Advantageous developments of this locking system are dependent on the formulated claims specified. The features specified in the claims individually can in any technologically meaningful way combined with each other become and lead to further embodiments of the invention. The specified characteristics in the claims will be further specified in the description, with special emphasis as well preferred embodiments of the locking system can be shown.

Therefore becomes a locking system for a motor vehicle door a plurality of spaced-apart positionable closing elements and one of the closing elements spaced common control unit for operating these closing elements proposed in which the control unit erscheibe a multi-part STEU having at least a first control disk with an actuating unit is connected and a second control disk is provided, the with several locking elements each over a means of transmission is connected, wherein the first control disk and the second control disk can be decoupled.

in the With regard to the design of the locking system, it should be noted that this one hand, as a kind of kit can be present at a Motor vehicle door or another, in particular initially mentioned, construction is fastened; However, it is also possible that the locking system already regarding one of these constructions or motor vehicle doors is mounted. Even if primary here is placed on an application on a motor vehicle door, closing systems for flaps, roof structures and the like also be included.

Regarding this Motor vehicle door are now several locking elements can be positioned or positioned at a distance from one another. Prefers are at least three closing elements provided, if necessary, e.g. also four locking elements. As a closing element In particular, locking systems are considered that with a cooperate with other component of a motor vehicle, such as another motor vehicle door, the vehicle body, the so-called A-, B- and / or C-pillar. Next with normal door locks Can lock also other bolt systems, anchors and the like (such as so called doorstop) includes his.

These closing elements are now from ei operated ner common control unit, which is positioned or positioned at a further position of the vehicle door. All in detail later explained actuating actions for the closing elements, which can be initiated by a person, for example, are brought together in the control unit, starting from the control unit, the closing elements can then be actuated via a respective transmission means. In this case, at least two of the closing elements are actuated simultaneously by the control unit, in particular all closing elements designed in the manner of a door lock are included.

For one particularly simple construction of the control unit is now a multipart Control disc proposed, wherein at least a first control disk with the operating units connected to initiate a closing element operation is. Another, second control disc now causes (under certain conditions) a simultaneous handling of the closing elements, in particular of all Door locks of the Motor vehicle door. This means in other words, in particular, that only incoming actuation requests supplied to the first control disk be and only actually incoming, outgoing actuation prompts be caused by the second control disk. Thus the incoming operating prompts considering various locking states of the locking system be forwarded (or not), are the first control disc and the second control disc designed decoupled. Particularly preferred this decoupling performed mechanically.

These Coupling has the consequence in particular that a first control disk acting movement according to the state of the coupling to the transfer second control disk can or not. Very particularly preferably lead the first control disk and the second control disk at least partially a joint rotation around a common control axis during the active state of the coupling off, while in the inactive state the coupling only enters a rotation of the first control disk. This construction is the basis for a very simple design Control unit, which also very space-saving and flexible expandable can be provided.

According to one advantageous development of the locking system is the first control disk with a first, outer, operating unit connected to means for decoupling from the second control disk dependent on several deactivation mechanisms are provided. With a first, outer, operating unit is in particular an outside door handle meant, wherein its activation via corresponding transmission means can be forwarded to the first control disc. The first Control disk also acts with means for decoupling of the second Control disc together, such as a clutch lever or like. Dependent on of several inactivation mechanisms, the decoupling of the first control disk are made by the second control disk. Possible Deactivation mechanisms relate to the central locking state, the inside lock state and / or a lock cylinder lock state. These states can mechanically and / or electromechanically and / or electrically queried become. Based on this, the Means for decoupling are transferred to a state, so that the first Control disc and the second control disc are decoupled. Especially preferred is the variant in which two or three inactivation mechanisms acting on the means for decoupling the first control disk.

Of Further, it is also suggested that a third control disc with an operating unit is connected, wherein the second control disk centrally and decoupled is arranged to the first control disk and the third control disk. For one It is particularly compact design of the multipart control disk advantageous in that all three control discs on a common control axis are positioned pivotally to each other. This show the control discs (partially) different outer contours (Edge courses in the circumferential direction of the control discs), which are used for driving of transmission means and the like are formed. It is particularly preferred that the second control disk with the first or the third Control disc with active coupling with moves, so they relatively to the other two, preferably on both sides of the second control disk arranged, control discs is movable. The third control disc For example, with a non-contact operating unit and / or a mechanical actuator, the in particular from the first, outer, actuating unit is different, interact.

Furthermore, a variant of the locking system is preferred, in which a third control disk is connected to a second, inner, actuating unit, wherein means for decoupling from the second control disk are provided as a function of at least one inactivation mechanism. The second, inner, actuating unit is, in particular, a door inside handle of the motor vehicle door. With regard to the decoupling of the third control disk from the second control disk is to refer to the corresponding, previous explanations regarding the first and the second control disk. Here it is preferred that one or two deactivation mechanisms are taken into account, in particular the Zu stood a parental control.

According to one Particularly preferred embodiment of the locking system is the multipart control disk connected to a drive, wherein the drive at least the Movement of a component of a closing element is effected. in the With regard to the movement of a component of at least one closing element is preferred that hereby an electric or electric motor supported opening and / or Pulling the components of a lock element is caused. With regard to the electric opening a closing element the case is preferred in which the drive at least to the second Control disc acts, which (if necessary rigid) on the transmission means with a Locking part of the closing element, in particular the pawl, cooperates. This has the advantage that separate drives on the door locks for an electric motor supported Lifting the pawl from the catch will not be needed. About that In addition, the drive can directly (or optionally also at least a control disk) the movement of another locking part, especially the catch, support. Should this feature in terms of all door locks be realized so are these (especially with regard to the electric motor supported Zuziehen) with a suitable catch to equip, in particular a so-called pre-rest and has a so-called main post. It was on This point pointed out that the aspect of the central Drive for moving at least one component of a closing element (if necessary to realize a quick release) also independent of the embodiment described here of the locking system with multipart control disc can be used advantageously.

In addition, will also a locking system proposed in which the multi-piece control disk with an actuator for at least a locking mechanism of the motor vehicle door is engageable, the motor vehicle door in an open Condition fixed. In particular, under a locking mechanism a so-called doorstop understood that at complete opened motor vehicle door with another Body components comes into engagement. Such a locking mechanism is in particular spring-biased, so that this with a corresponding Engaging device cooperates on the motor vehicle when the Motor vehicle door the complete opened Reached position. To disable this locking mechanism the multipart control disc can act on the actuator, in particular, overcome the spring force or closing force of the locking mechanism becomes. At the for this required movement of the multi-part control disk z. B. by the inside door handle and / or the outside door handle causes can advantageously be no components of the other closing elements moved, leaving only a very small force for deactivation the locking mechanism must be applied by the user. This can be achieved for example by who the that the control the respective pawls performs an idle stroke, in particular in consequence one opposite the basic position (main load) deflected position of the pawl at this time of deactivation of the locking means in the open Condition of the door.

Further It is proposed that the control unit at least the following components comprising: a multi-part control disk, a first clutch for a first Operating unit, a second clutch for a second actuator, a first motor in connection with the first clutch and a second one Motor in connection with the second clutch. This unites the Control unit already at least two clutches each preferred can be operated mechanically and / or electric motor assisted. Basically the user always has the option the actuators (Inside door handle, Outside door handle) switch itself, but this can also be done via corresponding sensors these places and / or over an electronic control unit and an identification transmitter (so-called keyless entry system) realized by the user. Preference is given to the coupling independently of each other mechanically or electromotively supported actuated. This will be the opportunity created, parental locks or central locks mechanically or over Enable (de) radio.

For one even more compact design of the locking system is also proposed that in addition comprises at least one of the following components of the control unit is: a drive for the multi-piece control disc, an actuator for at least one locking mechanism and a control system. With regard to the embodiments of Drive and the actuator should be to the above explanation directed. The control system includes in particular electrical or electronic components, such as sensors, microswitches, microcontrollers, Plugs, tracks and the like. The control system is used In particular, for the operation of the motors, but also other and / or more Take over functions. All of the above components may be provided with an outer cover attached to a part of the motor vehicle door, to protect against moisture and dirt or to keep each other in a defined position to each other.

Particularly preferred is a locking system in which the transmission means moved by the control unit are connected to a locking part of the closing elements. That means with others In particular, that there is a direct, possibly rigid, action of the control unit on the pawl or the rotary latch. Accordingly, the transmission levers, motors, microswitches and the like used in separate door locks are at least partially displaced into the common control unit, so that the parts expense can be reduced in the case of the several closing elements themselves.

The locking system can advantageously also be developed so that it in a sliding door a motor vehicle is integrated, wherein the closing elements in a wet area and the control unit with the operation of the closing elements power-supplied components is arranged in the dry area. In order to can in particular the functions of the electrically opening door lock, the electric motor supported Tighten the catch as well as electric motor assisted parental controls and / or central locks in the sliding door are realized so that the electricity leading Components such as motors, tracks, sensors, etc. relatively far away from the actual closing elements can be arranged while being protected from moisture. This advantage is further enhanced by the fact that towards the closing elements only mechanical transmission means used as for example linkage or Baudenzüge.

invention as well as the prior art are further illustrated by the figures. The figures show particularly preferred embodiments of the invention, to which this is not limited. They show schematically:

1 shows a variant of a locking system 1 on a motor vehicle door 2 That's like a sliding door here 25 is executed. Such a sliding door 25 is regularly parallel to the motor vehicle 28 shifted, for example, between a so-called B-pillar and a so-called C-pillar.

At the heart of the locking system illustrated here 1 is a central control unit 4 for operating a plurality of spaced-apart locking elements 3 , In the upper right area of the sliding door 25 is a first closing element 3 (for example, a so-called secondary lock) and in the right area of the sliding door 25 is another closing element 3 (For example, a so-called main castle) provided. In addition, the sliding door points 25 in the lower right area a third closing element 3 (For example, in the manner of a locking mechanism or a door stopper), and in the left area is a, sometimes referred to as a front lock, another closing element 3 arranged. The common control unit 4 can have separate transmission means 7 on all locking elements 3 act, this particular actuate or activate and / or deactivate. Furthermore, these actions are initiated jointly or individually by various actuation units, for example a first actuation unit 8th (eg door outside handle), a second operating unit 9 (eg inside door handle) and / or a sensor 29 for the contactless actuation of the motor vehicle door 2 , Based on these actuators switching operations in the control unit 4 activated, taking into account various locking states on the closing elements 3 act.

Left in 1 is enlarged and in a detail a concrete embodiment of a closing element 3 illustrated as a motor vehicle door lock. This closing element 3 includes two locking parts 24 on the one hand a catch 30 and on the other hand, a pawl 31 , For secure fixation on the motor vehicle 28 attached striker 32 locks the pawl 31 the spring-loaded rotary latch 30 advantageously initially in a so-called pre-rest 33 and finally in a main rally 34 , Preferred is an embodiment of the locking system 1 in which the control unit 4 about their means of transmission 7 directly on the pawl 31 or the catch 30 acts.

2 now illustrates in a cross section the structure of the sliding door 25 , A sliding door 25 can be in a wet area 26 and in a dry area 27 be subdivided, with regularly sealed walls to delineate this both areas. In connection with the locking system 1 it is preferred that the control unit 4 in the dry area 27 is positioned and via separate transmission means 7 with the individual closing elements 3 in the wet area 26 are arranged are connected.

3 shows, partially in perspective, a variant for a common acid control unit 4 , wherein a plurality of different operating and / or locking states with respect to the closing elements 3 are realized in a small space. For better illustration are in 3 various parts are marked with hatching or patterns, whereby an interaction of these parts should be illustrated. Below, these assemblies are once again illustrated in detail and explained their mode of action.

Central in the upper area of 3 the multi-part control disk is shown. This multi-part control disc comprises three control discs, which (temporarily) against each other rotatable on a common control axis 64 are positioned. Recognizable in this plan are the top control disc arranged above 5 and the underlying, second control disc 6 , The third control disc arranged underneath 12 is in a rear view of the control unit 4 recognizable as in 5 or 7 illustrated.

The first control disc 5 is via a means of transmission 7 hinged, which is marked with a crossed hatching. The combination of effects of the first control disc 5 with the second control disk 6 is through a first clutch 16 decoupled. That's why were essential with this first clutch 16 interacting inactivation mechanisms or parts with an equal hatching. The mode of action of these components will be with reference to 4 explained in more detail.

The black marked transfer means 7 are executed here in the manner of a linkage and transmit the movement of the second control disk 6 on the locking elements to be operated 3 , In the illustrated embodiment, with the movement of the second control disk 6 directly three different, spaced-apart, closing elements 3 operated in the manner of a door lock. This will be explained in detail with reference to 7 shown.

The rear, not recognizable here, third control disc 12 acts with the transmission medium shown above, marked with small dots 7 together. The combination of effects between this third control disc 12 and the second control disk 6 is via a second clutch 17 separated if necessary, with the second clutch 17 acting components or levers having the same, dotted, marking. This mechanism will be explained in detail with reference to 5 explained.

In addition, the control unit shown here includes 4 a control system 20 in particular for driving various electric motors, for detecting positions of the components illustrated here, and the like.

On the outer contour of the multi-part control disk further, here illustrated, components or modular assemblies can be positioned, which cooperate with the movement of the multi-part control disk. For example, above the control system 20 a drive 13 to recognize the with the appropriately marked transfer agent 7 can cause the movement of a component of a closing element. This process is related to 6 shown in more detail.

Finally, the control unit includes 4 as an additional module an actuator 14 for a locking mechanism. The related movements are with 7 shown.

Such a control unit 4 is advantageously modular. This means in particular that the assemblies comprising the drive 13 and / or the actuator 14 as well as the associated functions also independent of this concretely proposed control unit 4 can be realized. The integration of these modules in the central control unit, however, brings considerable benefits.

4 now illustrates in detail the motion sequences, the interaction of the first control disk 5 with the first clutch 16 and the second control disk 6 occur. The first control disc 5 is here with the so-called outside operating lever 35 connected, so that, for example, the movements of an outside door handle the vehicle door on the first control disk 5 Act. As a result of activation of the outside door handle is therefore the external operating lever 35 in the direction indicated by the black arrow. This leads to a correspondingly marked rotation of the first control disk 5 , The movement transfer to the (not shown) second control disk 6 takes place via the first clutch lever 38 , on the one hand, on the first control wheel 5 and on the other in a first tour 36 the second control disk 6 is stored. Turns the first control disc 5 So this movement is via the first clutch lever 38 and the first guide 36 on the second control disc 6 so that they synchronously rotate around the common control axis.

Under certain conditions, however, it is not desirable that when operating the outside door handle opening of the second control disk 6 controlled closing elements 3 he follows. For this reason, in the embodiment illustrated here, the first clutch lever can be used 38 three different inactivation mechanisms 10 . 11 and 21 act to the effect between the first control disc 5 and the first clutch lever 38 to prevent. To become inactive, the first clutch lever becomes 38 in the manner indicated by a white arrow, the first guide 36 moved toward the control axis, so that with a corresponding movement of the first control disk 5 an idle stroke takes place because of the first clutch lever 38 then into the first recess 37 the first control disc 5 inside moves. This is the second control disc 6 still, even if the first control wheel 5 rotates.

The first inactivation mechanism 10 relates, for example, to the case where a lock cylinder located on the motor vehicle door is mechanically transferred to a locked state. Such a lock cylinder now acts on the illustrated outer lock lever 39 , which is moved in the direction of the 3-fold arrow. This leads to a corresponding rotation of the first driver 40 about its axis of rotation, wherein the first driver 40 (below) on the first clutch lever 38 attacks and him in the first lead 36 emotional. This now leads to the first control disc 5 and the second control disc 6 are decoupled from each other. Will now be the outdoor operating lever 39 moved in the opposite direction (unlocking the lock cylinder), this movement is reversed, so that the action between the first control disc 5 and the second control disk 6 is restored.

A second inactivation mechanism 11 concerns, for example, a so-called internal locking. For this purpose, on the vehicle door push buttons and / or switches or the like may be provided, with which the user of the motor vehicle, starting from the interior of the motor vehicle, the closing elements 3 or disable the actuators. If he presses one of these push buttons or switches, so the inner locking lever moves 46 down, as shown here with a double arrow. Starting from this movement is the turntable 41 moved around its pivot axis, wherein the on the rotary plate 41 hinged first clutch lever 38 so guided that the two control discs 5 . 6 be separated again. This movement is reversible and is achieved by a corresponding operation of the internal locking lever 46 initiated.

However, here, in general, there may be a, possibly radio-transmitted, central locking, the third inactivation mechanism 21 can form. It is particularly preferred that this inactivation mechanism 21 also on the turntable 41 acts there and causes substantially the same movements as the inside lock lever 46 , For this it is suggested that a first engine 18 is provided, which are acted upon when necessary with power and a first worm wheel 42 on a first rotation part 43 can act. The first engine 18 is designed so that it can rotate in both directions, leaving the third inactivation mechanism 21 in the same way (as all other inactivation mechanisms also) the coupling of the first control disc 5 and second control disc 6 can cause. To be in operative engagement with the rotary plate 41 to get to, the first rotation part 43 two projections 44 put in a suitable receptacle 45 the turntable 41 can intervene. Here are two projections 44 realized, regardless of the direction of rotation as fast as possible with the rotary plate 41 to get in touch.

With Let the compact and simple arrangement illustrated here a considerable number of inactivation mechanisms already exist realize two decoupled control discs.

The control unit 4 as they are in 3 is illustrated with an additional, third control disc 12 executed. This is in a rear view now in 5 shown. The third control disc 12 is on the, the first control disk 5 opposite, side of the second control disk 6 arranged and also around the common control axis 64 hinged rotatable. The effective conclusion for a common rotation of the second control disk 6 and the third control disc 12 is via a second clutch lever 50 realized, this operative conclusion corresponding to that between the first control disk 5 and the second control disc 6 is executed. Part of the second control lever 50 is again in a second lead 48 the second control disk 6 movable, so that he moved in the decoupled state upward along the arrow shown in white and in the second recess 49 is positioned when, for example, a movement via an internal operating lever 47 in the third control disc 12 is initiated.

To perform such decoupling is a fourth deactivation mechanism 22 and a fifth inactivation mecha mechanism 23 with respect to this second clutch lever 50 provided.

Thus, the fourth inactivation mechanism takes into account 22 for example, a manual child safety device. This is activated, for example by the child safety lever 54 is shifted in the manner indicated by a double arrow, the second driver rotates 51 about its axis of rotation and engages (below) on the second clutch lever 50 and moves it in the desired manner. Here is the second driver 51 designed only on one side, so that, for example, by a suitable spring bias of the second clutch lever 50 it is ensured that this retracts into the illustrated position when the child safety lever 54 is moved back.

To allow here also the possibility of activating the child safety device over a greater distance, this movement of the second clutch lever 50 also using a second motor 19 respectively. This second engine 19 drives a second worm wheel 52 that's its rotation on a second rotation part 53 transfers. By investing this second rotary part 53 to the second clutch lever 50 this can be moved upwards, with opposite rotation of the second rotary part 53 the spring preload ensures that the second clutch lever 50 moved back again.

As already indicated, the in 3 illustrated variant has been supplemented by further modular assemblies. This concerns, for example, a drive 13 for electrically opening the door lock, or for electrically assisted closing of the door lock. This assembly will be described with reference to 6 explained.

A realization of the electrical opening or closing of a door lock is a third motor 56 in the control unit 4 provided, for example, on a, various electrical components 55 comprehensive, control system 20 is controlled. With this third engine 56 becomes a third worm wheel 57 driven, that its rotation on a third rotation part 58 transfers. About one with the third part of rotation 58 cooperative role 59 Among other things, the multi-part control disk can be driven (directly). The third engine 56 is again operable in both directions, so look for the role 59 that with the third part of rotation 58 is engaged, can realize both directions of rotation, as shown with the different colored arrows. Will be the third engine 56 so operated that a rotation of the roll 59 in the direction of the black arrow, comes the cam 60 for attachment to the stop 61 the second control disk 6 and lets them rotate (here counterclockwise) so that the closing elements are made. Since hereby the transmission center act directly on the respective pawls, so a fast, electromotive lifting the pawls of all desired closing elements is possible.

In special cases, which may also be independent of parts of the invention specifically described here, it may be useful by means of the drive 13 a quick release of the closing elements 3 to realize. This means, in particular, that a direct electromotive adjustment of the second control disk 6 about the role 59 or its cam 60 is initiated, leading to the lifting of the pawls of the rotary latches of at least two door locks or to control actuating levers, which in turn are responsible for the opening of the locking parts. The scenario in the context of a so-called "keyless entry system" with quick release could thus proceed as follows: A user with an identification transmitter approaches the motor vehicle and presses or touches the outside door handle (outer operating unit), creating a question and answer dialog between, for example, the control system 20 and the identification transmitter is started. If the comparison of the transmitted or queried data is positive, the drive immediately becomes active 13 activated for the electrical opening of the door locks. This causes a very rapid lifting of the pawls. Subsequently, the drive 13 brought back to its original position, so that the mechanical components can then be tracked. Thus, in particular the advantage is achieved that a previously possibly necessary unlocking or coupling the control discs is avoided, this process is subsequently made up.

In a reverse operation of the third motor 56 the role turns 59 in the direction of the white arrow, being an opening lever 62 is moved in the direction indicated by the white arrow. This relative movement can be exploited to support (indirectly or mechanically) the rotation of the rotary latch from a pre-locking position to a main locking position. Even if here only one opening lever 62 is provided for a single closing element, however, several such opening lever can 62 with the role 59 get connected.

With This unit is thus a very compact arrangement for electric motor supported opening and / or Shut down one and / or more closing elements in particular, in which only a single (central) engine needed becomes. This concept may also be independent of the decentralized locking system proposed here can be used.

• – der ersten Steuerscheibe 5, die mit der ersten Kupplung 16 zusammenwirkt,
• – der dritte Steuerscheibe 12, die mit der zweiten Kupplung 17 zusammenwirkt und
• – der zentral und auf der gleichen Steuerachse 64, angeordneten zweite Steuerscheibe 6, die zur Betätigung der diversen Türschlösser der Schiebetür mit einem Hauptschlossbetätiger 65, einem Nebenschlossbetätiger 66 und einem Vorderschlossbetätiger 67 verbunden ist, und diese Türschlösser gemeinsam und synchron betätigt.

In 7 Finally, the integration of a doorstop function is illustrated. In the left area of 7 is again in perspective the three-piece control disc illustrated with

• - the first control disc 5 that with the first clutch 16 cooperates
• - the third control disc 12 that with the second clutch 17 interacts and
• - the central and on the same tax axis 64 , arranged second control disk 6 used to operate the various door locks of the sliding door with a main lock actuator 65 , a sub lock operator 66 and a front lock actuator 67 connected, and these door locks operated together and synchronously.

The rotation or rotation of the second control disk 6 is doing through the first control disk 5 , or the illustrated external operating lever 35 , and / or the second control disk 12 , or the inner operating lever 47 , caused.

In the right area of 7 is a pivotally mounted actuator 14 shown, which is in contact with the outer contour of the three control discs, in particular when the locking mechanism 15 with the motor vehicle 28 is engaged. The deactivation of the locking mechanism 15 , which is active only in the fully open position of the sliding door, can take place via an actuating unit, so that the rotation of one, several or all control discs 5 . 6 . 12 for deflecting the actuator 14 and thus for deactivating the locking mechanism 15 leads.

It is preferred that the hub to be realized by the control discs for deactivating the locking mechanism 15 only as large as a free stroke with respect to the actuator 65 . 66 and 67 , This idle stroke results from the deflected position of the pawls in the door lock with the rotary latch open. Thus, the forces occurring in this process are very low.

All Here proposed developments of this shooting system to lead individually to a central control unit under consideration of various locking states, Doorstop functions and electrically support Closing operations.
