engine has.

In the generic embodiment (earlier patent application P 29 11 681.2-15 of the applicant) the control switching device is classic, designed without special control electronics, although it can be assumed that the control commands described are limited in time. The servomotors are designed to withstand the electrical loads that occur take up. The electrical load is there when the lock position is on theft protection is switched on for a relatively long period of time. All of this has proven itself, but is proportionate in terms of the circuitry complicated and requires servomotors with a corresponding load capacity and consequently a complex design.

In contrast, the invention is based on the object of simplifying the generic circuit arrangement and so on to train that with simple, only for short-term exposure from Z. B. one second set up, small servomotors can be worked, according to a preferred embodiment so that only a single additional switch of a simple design is required, the anti-theft device initiates or dissolves and also puts the corresponding servomotors into operation.

To solve this problem, the invention teaches that the circuit arrangement has control electronics with two control relays and two duration levels with impressed duration,

initially by the VR command and the ER command can be controlled alternately so that the servomotors each have one over the associated duration level Receive the actuating current pulse of the impressed duration,

and that also for the theft protection, the time duration level, which responds to the VR-3efehl, a second time by the DS command can be controlled so that the servomotors again receive an actuating current impulse of the impressed time period and the adjusting elements of the adjusting drives can thereby be moved into the anti-theft position, and that finite For the release of the anti-theft device, the time step that responds to the ER command can be controlled by the ES command is, v / o by means of the servomotors can be moved from the anti-theft position into the unlocked position. - The impressed time period is of course chosen so that the actuators lock the commanded positions or unlock. It amounts to z. B. a second, so that with set up for short-term exposure, simple electric servomotors can be worked. The invention is also based on the knowledge that such servomotors for the anti-theft device can be operated again easily and without the risk of overloading, if the duration level which responds to the VR command can be controlled a second time by the Dß command.

As a result, you first come to the servomotor Respect to an elegant solution to the task of the invention, which but can also be easily connected in terms of circuit technology.

real lets. It is particularly advantageous that only one additional, simple switch can be used, which takes over the control of the timer that responds to the VR command for the theft protection, i.e. initiates the DS command as well as the current control to the Servomotors, i.e. the DS command execution, takes over. That is in the following with reference to a drawing showing only one embodiment, which also includes further features of the Invention disclosed, explained in more detail.

Locking lever 8 engages and can be driven from an unlocking position I with a locking stroke VH into locking position II. In FIGS. 1 and 2, the functional position is unlocked both in the door lock 1 and in the actuator 2 drawn drawn, - the position Locked was indicated by dash-dotted lines. The control switching device 3 is provided with a locking circuit 10 as well provided with an unlocking circuit 11 with the Key or a dashboard switch is switchable and controls connected circuits 12 accordingly. It however, additional measures are implemented, 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 Anti-theft device hub DH in anti-theft position III drivable,

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

The circuit arrangement has a lock cylinder 2 4 on the driver's door and thus the corresponding key Switchable control switching device 3 for a VR command, a DS command, an unlocking command and an unlocking command. The circuit diagram of FIGS. 3 to 5 and 6 is adapted to the locking device according to FIGS.

Fig. 3 shows the inoperative state / d. H. the condition Unlocked, key withdrawn. In FIG. 4 the VR command flows to the servomotor 15, in FIG. 5 the DS command. The one with it Lines and contacts carrying positive potential are drawn out thickly in the diagram of FIGS. 4 and 5. The leading negative potential Contacts are bold dash-dotted lines. The functionless ones Lines and contacts in FIGS. 4 and 5 are drawn out 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. 6.

In detail, the lock cylinder 24 can be seen in the diagram of FIGS. 3 to 5 and 6, respectively.

the switch 25 for operating the centrally controlled locking device, which is usually available anyway,

the electric servomotor 15, the control electronics 26 and

the additional switch 27 for theft protection.

In the unlocked positions of FIGS. 3 and 6, all lines are de-energized. The bold ones already explained Lines in FIGS. 4 and 5, which illustrate lines carrying positive potential, as well as the thick and dash-dotted lines Solid lines, which represent lines carrying negative potential, allow the flow of current in the Functional positions locked (Fig. 4) and anti-theft (Fig. 5) to be followed:

From a functional point of view, this is taken from a comparative Consideration of FIGS. 3 to 5 and 6 first of all that the circuit arrangement comprises control electronics 26 with two control relays 28, 29 and two duration stages 30, 31 with an impressed duration.

These control relays 28, 29 or duration stages 30, 31 are initially triggered by the VR command and the ER command can be controlled alternately so that the servomotors 15 each have one via the associated duration stage 30 and 31, respectively Receiving actuating current pulse of the impressed time period.

The arrangement is made so that the time duration stage 31, which responds to the VR command, a for the theft protection can be controlled a second time by the DS-3 command of the control switching device 3. This causes the servomotors 15 again an actuation current pulse of the impressed time

hold and that the adjusting elements 9 of the adjusting drives 2 are thereby moved into the anti-theft position III. The order but is also made so that for the resolution of the anti-theft device, the duration level on the ER command responds, can be controlled by the ES-3efehl, whereby the servomotors 15 from the anti-theft position III can be moved directly into the unlocking position I. It can also be seen from the circuit diagrams that the control switching device 3 has only one additional switch 27 for the DS command. The embodiment is chosen so that the duration stage 31 can be controlled by an applied negative potential. The additional switch 27 for the DS-3efehl has only two switch positions and is a simple changeover switch with reed, reed bearing and two switching contacts designed. This additional switch takes over the control of the timer, which is based on the VR command responds, so the initiation of the DS command and the distribution of the operating current from the control electronics to the Servomotors so that they move into the DS position, i.e. the execution of the DS command. Otherwise, the circuit in Fig. 6 is made so that at least for the duration stage 31, which responds to the VR command, one is used that is additionally caused by a missing potential, d. H. potential-free, controllable.

The scheme of FIG. 6 is basically easy to understand with the reference numerals explained above. It shows the embodiment in which the duration stage 31 again can be controlled by an applied negative potential, but in which the circuit is made so that at least
