directions, be they electrical or pneumatic, acts through the immobilization of a locking member mechanical lock. After all, these solutions are relatively complicated if one considers all the possibilities who want to keep classic locks;

the hand control in the event of a breakdown,

the exclusion of a blocking of the doors from the Outside of the vehicle when the ignition key is inside,

the independent actuation of one of the two front

doors,

actuation from inside the vehicle.

If the doors are equipped with electric locks, they can be opened individually by energizing one of the If there is an electromagnet that disengages the bolt of the lock, it is apparently very easy to lock bring about by breaking the circuit that connects all electromagnets to the power source ;. However, the solutions known so far, which use a remote switch, for example, do not offer sufficient adaptability, to solve all of the above tasks ..

The invention addresses these disadvantages to fix.

The invention thus relates to a control device for the simultaneous locking and unlocking of a group of

Four electromagnets (i2a and 12b for the front doors and 12c and 12d for the rear doors) like that shown in FIG Electromagnet 12 are between line 25 and connected in parallel to the ground "

Every electromagnet can be energized;

either by closing a switch which is connected to a switch button 30a, 30b, 30c or 3Od, which is accessible from the outside of the vehicle, such as the push button 30 on the outside latch 31 of the door P. (Fig. 1) is attached,

or by closing a switch connected to a switch button 32a, 32b, 32c or 32d, which is accessible from the vehicle interior, such as the push button 32, which is mounted in a niche 33 of the inner wall of the door P (Fig. 1).

The door switches 32c and 32d are also connected in series with a changeover switch "} h , which, when it is open, supplies a control lamp 35 with current with its other contact. This switch 3h is the" child safety switch ".. When it is open is ,, it renders any operation of the internal switches 32c and 32d ineffective.

The blocking coil 28 of the bistable relay 27 is connected in series with one or the other of the two switches 22a and 22b _t such as the switch 22 of FIG. 1, which are connected to the locks of the front doors, and also with a switch 3 ^ for the lock is connected in series from the inside, which is operated by a push button.

The unlocking coil 29 of the bistable relay 27 is connected in series with the following switches connected in parallel: a switch 37 »which is open in the normal position, the switches 21a and 21b which are open in the normal position, which are connected to the locks of the front doors and the one on each door Attached stop contacts 38. These stop contacts 38j, which are open when the doors are closed, are generally used to switch on the ceiling light 39. The switches J6 and 37 are operated by a single pressure piece, which is designed as a rocker and can assume two unstable and one stable position; in the stable position, the two switches 36 and 37 are open.

The circuit diagram according to FIG. 3 finally has a switch kO which is actuated by the bistable relay 27 and is connected in series with the main switch 41 and an illuminated sign h2. The switch kO is closed when the switch 26 is open and vice versa.

The control device described above works in the following way:

When the vehicle is stationary, the doors are locked and locked and the child restraint is not is in operation, the various switches are in the position shown in Fig. 3 and the mechanical parts the locks in the position shown in Fig. 2 with full lines. You can see that it is impossible to use the electromagnet 12a and 12c to be supplied with electricity by turning the switches 30a-30d or the corresponding switches 32a

to 32d closes as long as switch 26 is open.

The vehicle can be opened from one or the other front door with a key in the
Direction of rotation of the arrow F (Fig. 2) is rotated until the lever arm 20 brings the switch 21 to close. During this movement, the end of the arm 14 slides in the slot 15
the coupling rod 16, and the toggle lever 17 remains immobile. Closing the contacts 21a or 21b on one side or the other of the vehicle puts the release coil 29 under tension, whereby the contact 26 is closed. Then all the doors are unlocked and it is possible to open them from the inside as well as from the outside by pressing one of the buttons 30a-30d or 32a-32d, whereby one of the electromagnets 12a-12d
the corresponding door is operated.

If, by chance, the switch 21 does not work, if the key continues to turn in the direction of rotation F. the
Arm 14 with the coupling rod 16 and then the toggle lever 17,
whereby the lever 10 is pivoted, which in turn releases the door bolt 1. The opening of the door and the resulting closing of the corresponding stop contact 38 causes current to be applied to the coil 29 and thus the unlocking of all doors.

If the entire electrical system fails, e.g. B.
When the battery is discharged, it is still possible to open the front doors mechanically, either from the outside, as described in the previous paragraph, or from the inside, using the handle 8, and the rear doors can also be opened using the corresponding handles will.

The locking from the outside is brought about on one of the front doors by the lock bolt 13 by means of of a key in the direction of arrow F ″ (Fig. 2). The arm 20 then closes the switch 22, thereby energizing the interlock coil 28, and opens so switch 26. The doors can then no longer be opened from the outside without a key.

During the rotation of the lock bolt in the direction of the arrow F ₂ , the arm Ik slides in the slot 15 of the coupling rod 16, and the toggle lever 17 remains immobile.

The switch 36 allows, if one so desires, to lock the doors from the inside. In this case, the unlocking is brought about either by closing the switch 37 or by opening one of the doors. If the unlocking is brought about by opening one of the doors, locking from the outside is excluded as long as the key remains inside.

If the locking is brought about as long as the switch kl is closed, which corresponds to the case in which the locking is controlled from the inside, the illuminated symbol k2 remains illuminated.
