wherein the control holding device comprises control electronics with two control relays and two duration levels that can be triggered by applying a negative potential has an imprinted period of time that can be alternately controlled by the VR command and the ER command, that the servomotors each have an actuating current pulse of the impressed on the associated duration stage Maintain duration.

DE-OS 27 57 246 discloses a generic control circuit device for a centrally controlled locking device Known without anti-theft device for motor vehicle doors This control switch device has είπε control electronics with two control relays and two duration levels with stamped Zeitdäcier on, which can be controlled alternately by a VR command and an ER command. This is done over the duration levels a current pulse of a given duration to the, the electromechanical actuators for the centrally controlled door locks assigned servomotors, which consequently move in the open direction or move in the closing direction depending on the position of the relay. Compared to a classic, without spreader electronics The control circuit device implemented can be used with a relatively simple, only for short-term load set up, small servomotors are worked.

In a centrally controlled locking device for motor vehicle doors, which according to DE-PS 29 11 681 an additional anti-theft device has, the servomotor continues to run an actuating step following the close command, if with the Key the Fosition anti-theft device (DS) is operated. The control circuit device must have an additional Have switches and control electronics with a further duration stage with an imprinted duration, so that the actuation current pulse can be triggered.

In contrast, the invention is based on the object of providing the generic circuit arrangement Simplify and train so further that the control electronics only have two duration levels with impressed Has duration and designed as a simple switch switching elements.

To solve this problem, the invention teaches that for the theft protection, the duration level that responds to the VR command can be controlled a second time by the DS command, so that the servomotors again receive an actuating current pulse of the imprinted duration and the actuating elements of the actuators thereby are movable into the anti-theft position so that the time stage that responds to the ER command can be controlled by the ES command for the resolution of the anti-theft protection, whereby the servomotors can be moved from the anti-theft position directly into the unlocked position. With regard to the renewed activation of the duration stage assigned to the VR command, two embodiments are claimed. According to claim 1, the circuit arrangement is characterized in that the control circuit device has a switch designed as a simple changeover switch for the DS command, that on the bearing of the switch tongue of the switch for the DS command! negative potential is applied via one or more servomotors and "after switching the switch, the duration stage can be controlled by this negative potential, whereby the associated time relay is excited, and that the current flows in the opposite direction (positive potential) to the servomotor via the same line and" with unchanged switch position . According to claim 2, the Schahungsan-arrangement is characterized in that the control circuit device has a switch designed as a simple changeover switch for the DS command, and that at least for the duration level that responds to the VR command, one is used which is also through Switching off a negative voltage can be controlled. and when the switch is switched from one switch position to the other, the control pulse for the duration stage can be triggered.
The imprinted period of time is of course chosen so that the actuating drives adopt the commanded locking or unlocking positions. It amounts to z. B. one second, so that you can work with simple electric servomotors set up for Kui ^ 'ci! The invention is also based on the knowledge that such servomotors for theft protection can be operated again easily and without the risk of overload if the duration level that responds to the VR command can be controlled a second time by the DS command is.

The result is an elegant solution to the problem of the invention in terms of servomotor technology, but which can also be easily implemented in terms of switching technology. It is of particular advantage that only one additional, simple switch can be used, which is used for theft protection as well as the control of the timer, which is based on the VR command! responds, takes over, i.e. initiates the DS command, as well as the current control to the servomotors, i.e. the DS command execution, C takes over. This is explained in more detail below with reference to a drawing which shows only one exemplary embodiment and which also discloses wide features of the invention. It show in a simplified representation
F i g. 1 a locking device with anti-theft device for motor vehicle doors, as can be integrated with the circuit arrangement according to the invention,

F i g. 2 in opposite to FIG. 1 on a much larger scale according to the actuator from the object F i g. 1 in different functional positions,

F i g. 4 and 5 show the schematic of FIG. 3 in the Functional positions Locked (Fig. 4) and anti-theft device (F ig. 5),

Fi g. 6 the switching theme of another embodiment a locking device according to the invention in the unlocked position.

The in F i g. 1 shown centrally controlled locking device is intended for motor vehicle doors. The basic structure initially includes
a mechanical door lock 1 provided on each automobile door. - but was only drawn once.

a reversible electromechanical actuator 2 on this centrally controlled door lock 1 and
a control switching device 3, which can be actuated with the key of a lock cylinder, for the actuating drives 2.

In the embodiment, the switching device may be in the driver's door, like the door lock 1 can be arranged with its actuator 2 in a rear door. The electrical connection shown schematically 4 between control switching device 3 and actuator 2 shows branches 5 that lead to other motor vehicle doors to lead. In the embodiment of FIG. I, the actuator is self-locking, but not restrictive.

The assigned centrally controlled door locks 1 have a latch 6 in the exemplary embodiment Locking pawl 7 and a locking device with locking lever 8, the locking lever 8 of which from the associated actuator 2 can be actuated. It can also be seen that the adjusting drives 2 are an adjusting element 9 have which engages the associated locking lever 8 and from an unlocked position 1 can be driven with a locking stroke VH in locking position II. In Figs. 1 and 2 is the Functional position unlocked both in the door lock t and in the actuator 2 has been drawn in solid lines, - The locked position was indicated by dash-dotted lines. The control switching device 3 is provided with an interlock circuit 10 and provided with an unlocking circuit 11, which with the key or a Dashboard switch is switchable and controls connected circuits 12 accordingly. However, there are Realized additional measures, namely

a) the control switching device 3 has an additional, key-operated anti-theft device 13,

b) the adjusting element 9 of the adjusting drive 2 is beyond the locking position II with an additional Theft protection hub DH can be driven in theft protection position III.

c) the door locks 1 have an additional anti-theft lever 14.

As already mentioned, in FIGS. 1 and 2 the unlocked position Drawn in solid lines, the locking position and the additional anti-theft position NI are shown in dash-dotted lines. The arrangement is such that the anti-theft lever 14 takes the locking lever 8 with the locking stroke VH and back and when Anti-theft protection hub DH the pawl 7 and the locking lever 8 blocked, with the corresponding Return stroke of course solves.

The F i g. 2 shows that the steep drives 2 of the centrally controlled Door locks 1 in the exemplary embodiment a reversible. rotating servomotor 15 with connected Have adjusting threaded spindle 16 and thereon self-locking adjusting nut 17 on which a Actuating lever 18 engages. This is a double-armed one Adjusting lever 19, 20 with connecting lever arm 19 and blocking lever arm 20 assigned between the operating lever 18 and adjusting lever 19. 20 there is an overload protection device 21. This takes place when the Actuating lever 18 from the unlocking position I into the locking position II the adjusting lever 19.20 with - as in Fig. 2 was shown in phantom. In addition, the arrangement is such that the operating lever 18 for the anti-theft device hub DH - controlled by the corresponding electrical circuit of the Switch 22 - this overload safety device 21 passes over and acts on the locking lever arm 20 and moves this in anti-theft position HI. - as shown in FIG. 2 was indicated by dashed lines. For actuation the control switching device 3 can be operated with a conventional lock cylinder, which then allow an anti-theft position III in addition to the unlocking position I and the locking position II got to. All three positions can be set with one and the same key or the anti-theft position III can be set with an additional key. It is finally possible for the anti-theft circuit 13 to provide a special lock cylinder, which then with that for the locking device usual key or with an additional key.

The structure of the door locks 1 is basically arbitrary. Parallel and coaxial to the locking lever 8, the anti-theft lever 14 is arranged in the embodiment. From this is interposed a spring 23, the locking lever 8 can initially be carried along when the adjusting lever 19, 20 moved from the unlocked position I into the locked position II. Through the anti-theft hub DH, however, the locking lever 8 and the pawl 7 can then be blocked, whereby the anti-theft lever 14 executes his anti-theft device stroke DH and thereby the force of the aforementioned spring 23 overcomes and thereby grips behind a cam 8a on the locking lever 8 in a locking manner with a nose 14a and with its locking arm 14i> in the range of motion of the pawl lever arm 7a pivots and thus takes over the blocking of the pawl, namely

jo for locks without additional type Bb - corresponding dash-dotted representation -, i.e. without a device for interrogating the position of the pawl.

An associated circuit arrangement according to the invention has been explained in FIGS. 3 to 5, specifically for the sake of simplification for a servomotor 15. The outgoing lines lead to other servomotors. The circuit arrangement has a control switching device 3, which can be switched with the locking cylinder 24 on the driver's door and thus the corresponding key, for a VR command, a DS command, an unlocking command and an unlocking command. The circuit diagram of FIG. 3 to 5 and 6 is attached to the closure device according to FIGS. 1 and 2 adapted.
F i g. 3 shows the inoperative state, ie the unlocked state, key withdrawn. In Fi g. 4 the VR command flows to the servomotor 15 in FIG. 5 the DS command. The lines and contacts carrying positive potential are shown in the diagram in FIG. 4 and 5 drawn out thick. The contacts carrying negative potential are thick dash-dotted lines. The inoperative lines and contacts are shown in FIGS. 4 and 5 sucked in as thinly as basically all lines in the diagram of FIG. 3, which, as already mentioned, corresponds to the unlocking position. This also applies to the embodiment according to FIG.
