In the presentation of the Fig. 1 and 2 is the latch 1 in a main latching position, which is a closed position and the pawl 3 is in the lowered position.

In the proposed motor vehicle lock an external operating lever 4 is provided, which is coupled in the installed state with an outside door handle 4a and wherein an internal operating lever 5 is provided, which is coupled in the installed state with a door inner handle 5a. Such couplings can each be realized with a Bowden cable or the like.

Next is provided in the proposed motor vehicle lock a central locking assembly 6, wherein the central locking assembly 6 a switchable central locking clutch 7, a - here only schematically illustrated - central locking drive 8 for motor switching of the central locking clutch 7 and a mechanically coupled or couplable with the central locking clutch 7, adjustable switching element 9 User-side influencing the coupling state of the central locking clutch 7, wherein the central locking clutch 7 in at least one clutch state "child-proof" in a coupling state "emergency locked" and in a coupling state "ground state" can be brought. It show the Fig. 1 to 3 the central locking clutch 7 in the coupling state "ground state", the Fig. 4 the central locking clutch 7 in a coupling state "child-proof" and the Fig. 5 the central locking clutch 7 in the coupling state "emergency locked".

In this respect, more than one "child-safe" coupling state may be provided, as this "child-secured" coupling state can be combined with other states of the central locking clutch 7, such as "locked" or superimposed leaves. The coupling state "emergency locked" can be taken about when, due to failure or a low power level of a voltage source for the motor vehicle lock, z. B. a car battery, no longer sufficient electrical energy for the operation of the central locking drive 8 is available. It can then be effectively prevented by bringing the central locking clutch 7 in the coupling state "emergency locked" a lifting of the pawl 3 by operating the outside door handle 4a. Once the central locking drive 8 can be operated again regularly, the central locking clutch 7, the clutch state "emergency locked" leave again, which will be described below in more detail.

According to the proposal, it is provided that actuation of the external actuating lever 4 and / or the inner actuating lever 5 causes the pawl 3 to lift depending on the coupling state of the central locking coupling 7, wherein in the at least one coupling state "child-fitted" an actuation of the inner actuating lever 5 is freewheeled or blocked. A lifting of the pawl 3 and thus opening of the motor vehicle lock associated closure element by actuation of the corresponding inner door handle 5 a is thus prevented.

According to the proposal is further provided that in the coupling state "emergency locked" an operation of the external actuating lever 4 is free running or blocked. It is preferred that the coupling state "emergency locked" corresponds to a coupling state "centrally locked". This means that in the coupling state "emergency locked" a lifting of the pawl 3 is effectively prevented by both the operation of the outside door handle and - beyond the coupling state "emergency locked" in the strict sense - by operating the door inner handle 5a. This variant corresponds to the embodiment shown in the drawing and will be described in more detail below.

In any case, in addition to these two coupling states, the coupling state "ground state" is also provided, in which case in principle any desired behavior of the central locking coupling 7 can be provided. In principle, any further coupling states of the central locking clutch 7 can also be provided. According to an embodiment which corresponds to that in the drawing and is preferred insofar, it is provided that in the Clutch state "ground state" causes both actuation of the inner actuating lever 5 and an actuation of the external actuating lever 4, a lifting of the pawl 3. Then the coupling state "basic state" corresponds to the coupling state "unlocked"

The proposed motor vehicle lock is now characterized in that the switching element 9 in a parental control position - shown in the Fig. 4 - And in an emergency locking position - shown in the Fig. 5 - It can be adjusted that an adjustment of the switching element 9 in the child safety position brings the central locking clutch 7 in the at least one coupling state "child-proof" and that an adjustment of the switching element 9 in the emergency locking position brings the central locking clutch 7 in the coupling state "emergency locked". According to the proposal, therefore, by adjusting a single element, here by adjusting the switching element 9, the central locking clutch 7 either in the coupling state "child-proof" or in the coupling state "not locked" are brought.

Preferably, and as shown in the drawing, the switching element 9 is a rotary nut 9a. However, the switching element 9 may also be a slide switch or a lever.

According to a preferred embodiment, it is provided that the switching element 9 can be adjusted by a first pivoting movement in the child safety position and by a second pivoting movement in the emergency locking position. In this case, as will now be explained in more detail, the second pivoting movement may be a continuation of the first pivoting movement.

Specifically, it can be provided that the switching element 9 can be adjusted to a basic position. This corresponds to the position of the switching element 9 in the Fig. 1 to 3 , In this case, it is preferable that an adjustment of the switching element 9 in the basic position brings the central locking clutch 7 in the coupling state "ground state". The central locking clutch 7 then works so far "normal" and without any special influence by the switching element 9. However, it can be provided by a different arrangement, regardless of the switching element 9 influencing the central locking clutch 7.

It is preferred that, starting from the basic position, the second pivoting movement has the same pivoting direction - locking pivoting direction 10 - as the first pivoting movement. The first pivoting movement is here of the switching element 9 during the transition from the position of Fig. 3 in the position of Fig. 4 made movement and the second pivoting movement of the switching element 9 in the transition from the position of Fig. 4 in the position of Fig. 5 movement made. The corresponding locking pivot 10 and the locking pivot axis 10 a, by which the switching element 9 is pivoted, is in the Fig. 2 to 5 shown. It is preferred that starting from the basic position by a pivoting movement in the locking pivoting direction 10, the switching element 9 can be adjusted only in the child-safety position and then in the emergency locking position.

It is preferred that the central locking drive 8 - in addition to the above-mentioned switching the central locking clutch 7 - is also adapted to lift the pawl 3 via the central locking clutch 7 by motor. Specifically, this can be done by operating a Sperrklinkenverstellelements 11 of the central locking clutch 7. This will be described in more detail below.

Further, it is preferred that the central locking drive 8 is adapted to actuate the switching element 9 via the central locking clutch 7 and, in particular, to bring it into the parental control position. If, for example, sufficient electrical energy is again available for the central locking drive 8, the "emergency locked" coupling state can be canceled in this way. The bringing into the parental control position can be done mainly by an operation of the Sperrklinkenverstellelements 11, which is also described below in more detail. Specifically, accordingly, the central locking drive 8 may be adapted to bring the switching element 9 from the emergency locking position to the child-safety position. Likewise, the central locking drive 8 but also be adapted to bring the switching element 9 from the emergency locking position to the normal position.

Specifically, when the switching element 9 has been brought into the emergency locking position, without the switching element 9 was already for a significant period in the child safety position, so the parental control position has taken only during the passage to the emergency locking position, it may be desirable, the switching element 9 from the emergency locking position to bring to the basic position. For this purpose, it is preferable for the motor vehicle lock to have a control device 12-shown here only systemically-for controlling the central locking drive 8 and for storing a positional state of the switching element 9. Then it is preferred that the control device 12 is adapted to store a previous adjustment state of the switching element 9 when the switching element 9 is moved into the emergency locking position. Then, in particular, the control device 12 may be configured to adjust by switching the central locking drive 8, the switching element 9 from the emergency locked position in the stored Verstellzustand.

Preferably, the motor vehicle lock is equipped with a motor vehicle lock housing, which is at least partially made of a plastic material. It is further preferably so that the switching element 9 is arranged in a housing portion formed of a plastic material. In a particularly preferred embodiment, this is a housing section which is accessible only when the vehicle door is open.

The provision of a separate access opening to the switching element 9 for the user is particularly unnecessary if - according to a preferred, not shown here variant, the motor vehicle lock a motor vehicle lock housing with an inlet mouth for receiving the striker 2 and the switching element 9 at the inlet mouth user-side adjustment is accessible. Because for the inlet inlet an opening for receiving the striker 2 is provided anyway, so that this opening may have another function and a separate access opening is no longer required.

With regard to the operation of the motor vehicle lock upon actuation of the door inner handle is preferably provided that the central locking clutch 7 has an inner clutch lever 13, which in a coupling position can be brought, in which the inner clutch lever 13 is disposed within the force action chain for lifting the pawl 3 upon actuation of the inner actuating lever 5. This coupling position of the inner clutch lever 13 is in the Fig. 3 to recognize. By operation of the inner operating lever 5, the inner clutch lever 13 is a in the plane of the Fig. 3 lying axis pivoted and engages lifting in the pawl 3 a. Furthermore, the inner clutch lever 13 can be brought into at least one uncoupling position, in which the force action chain for lifting the pawl 3 is interrupted upon actuation of the inner actuating lever 5. A first such uncoupling position of the inner clutch lever 13 is in the Fig. 4 and a second such uncoupling position of the inner clutch lever 13 is in Fig. 5 shown. As can be seen from a comparison of the representation of Fig. 3 with those of Fig. 4 and 5 results, the inner clutch lever 13 is free in the first and second uncoupling position when actuated by the inner operating lever 5 and thus does not lift the pawl 3.

Here, it is preferred that is displaced by an adjustment of the switching element 9 in the child safety position or in the emergency locking position of the inner clutch lever 13 in the at least one uncoupling position. Like from the Fig. 4 and 5 This is done in this embodiment by an engagement of a switching contour 9b with the inner clutch lever 13. It can also be provided only a single uncoupling position of the inner clutch lever 13 for both positions of the switching element 9.

With regard to an operation of the motor vehicle lock upon actuation of the outside door handle 4a is preferably provided that the central locking clutch 7 has an external clutch lever 14 which is blocked in a uncoupling position in which an actuation of the external operating lever 4 or runs free. This is in this uncoupling position of the outer clutch lever 14 specifically to a freewheeling position in which an operation of the external actuating lever 4 free running. Preferably, this external clutch lever 14 may - as here - be identical to, comprise or be encompassed by the above pawl adjustment element 11.

From the Fig. 1 It can be seen that in an adjustment of the outer clutch lever 14 in the - not shown here - freewheeling position which a pivoting around the in the Fig. 3 to 5 illustrated outer clutch lever pivot axis 14a in the clockwise direction as shown in FIG Fig. 1 corresponds, the external operating lever 4 can no longer lift with the pawl 3 engage. From the Fig. 1 also shows that thus the - indirectly via an outside door handle lever assembly 15 actuated - external actuating lever 4 is directed into a freewheel, which corresponds to the free-running of the external operating lever 4 in a crash. Preferably, by adjusting the switching element 9 in the emergency locking position of the outer clutch lever 14 is brought into the uncoupling position. The constructive implementation will be explained in more detail below.

In addition to the above-described uncoupling position of the outer clutch lever 14 is preferably provided that the outer clutch lever 14 in a basic position - here in the Fig. 1 and 2 shown - can be brought, in which an actuation of the external actuating lever 4 causes a lifting of the pawl 3. Preferably, the outer clutch lever 14 is biased in the basic position.

Specifically, according to the embodiment shown in the drawing can be provided that the outer clutch lever 14 is pivotally - here about the above Außenkupplungshebelschwenkachse 14a - is stored, the outer clutch lever 14 is in the basic position with respect to a pivoting in a Ausheberichtung 15a in aushebendem engagement with the pawl 3 and with respect to a pivoting in a direction of uncoupling 15b relative to the pawl 3 has a freewheel. In this way it is made possible, on the one hand by an operation of the outer clutch lever 14 to lift the pawl 3 and on the other hand to bring the outer clutch lever 14 in the above uncoupling position, without having to adjust the pawl 3.

It is further preferred that is pivoted by the adjustment of the switching element 9 in the emergency locking position of the outer clutch lever 14 in the uncoupling direction 15b and is preferably brought into its uncoupling position.

For constructive implementation can be provided for this purpose according to the illustrated embodiment that the central locking device 6 a Actuator 16 which engages with the outer clutch lever 14 and that by the adjustment of the switching element 9 in the emergency locking position, the switching element 9 so engages with the adjusting device 16 and actuates that the outer clutch lever 14 in the uncoupling position - preferably as shown here in the freewheel position - is brought. The engagement of the switching element 9 with the adjusting device 16 in an adjustment in the emergency locking position is from a synopsis of Fig. 4 and 5 out.

Preferably and as shown in the embodiment, the adjusting device 16 is an adjusting rod 16a. It is also preferred that the central locking clutch 7 has a latching arrangement 18 with latching points 18a, b and that the adjusting device 16 has a detent spring 19 for engagement with the latching points 18a, b. In particular, the adjusting device 16 may be adapted to engage with its detent spring 19 in a first latching point 18a, when the switching element 9 is pivoted into the emergency locking position. This is in the Fig. 5 shown. Further, the adjusting device 16 may be adapted to engage with the detent spring 19 in the second detent point 18b when the switching element is pivoted in the child safety position or in the normal position. This is in the Fig. 3 and 4 shown.

As already described above, the central locking drive 8 can also be set up to lift the pawl 3. For this purpose, it is preferably provided that the central locking drive 8 is adapted to adjust the outer clutch lever 14. Specifically, the central locking drive 8 may be adapted to adjust the outer clutch lever 14 so that the pawl 3 is lifted by a direct or indirect engagement with the pawl 3. In particular, it can be provided that the central locking drive 8 engages at a drive point 17 on the outer clutch lever 14 for an adjustment. Thus, by the central locking drive 8 of the outer clutch lever 14 can be adjusted or pivoted in Ausheberichtung 15a, whereby the pawl 3 is lifted. The central locking drive 8 can also adjust or pivot the outer clutch lever 14 in the decoupling direction 15b. In this way, the central locking drive 8 regardless of the switching element 9 a Coupling state "locked" of the central locking clutch 7 establish.

Likewise, it is preferably provided that the central locking drive 8, the outer clutch lever 14 can adjust so that, in particular by the adjusting device 16, the switching element 9 is taken. Specifically, the switching element 9 can be brought from the emergency locking position in the parental control position. For the embodiment shown in the drawing, this relationship results from a synopsis of Fig. 4 and 5 , This makes it possible to cancel the coupling state "emergency locked" approximately automatically by the central locking drive 8 when electrical energy is available again for the operation of the central locking drive 8.

Finally, it should be noted that preferably a fixation of the switching element 9 is provided in at least one position to avoid that an undesired adjustment of the switching element 9 occurs. Here and preferably, it is such that the switching element 9 is held mechanically stable in at least one position by means of a spring arrangement 9c. In the case of the spring arrangement 9c, this is a spring which is arranged on the switching element 9 and which can be brought into latching engagement with a contour K fixed relative to the switching element 9. This is in Fig. 3 exemplified. In the illustrated preferred embodiment, it is provided in particular that the switching element 9 is kept mechanically stable in the child-safety position, in the emergency locking position and in the basic position by means of a spring arrangement 9c. Alternatively, it may also be advantageous that the fixation is realized by means of a separate from the switching element 9 configured spring arrangement. In a further alternative, the fixation of the switching element 9 can be accomplished via the coupling of the switching element 9 with the rest of the lever system of the motor vehicle lock.

It may further be pointed out that in the illustrated preferred embodiment, the switching element 9 on the one hand and the central locking drive 8 on the other hand in each case act on the central locking clutch 7.

It may also be pointed out that in the illustrated and insofar preferred embodiment, the switching element 9 is arranged so that when mounted motor vehicle lock, the accessibility and adjustability of the switching element 9 for the user from outside the motor vehicle lock is readily possible.
