is arranged axially to the cover 4 ^{a of} the base housing 3 opposite the cover 4. The output shaft of the motor drives a planetary gear 13, via the output element of which the ramp mounting element 7 is fixed. It also has a generally cylindrical shape and is arranged centered on the axis XX by means of an axial shaft 14 which extends it and which is at its other end in a second annular flange 15 which is formed as an axially arranged projection of the inner surface of the cover 4, is rotatably arranged.

The motor 11 is a DC motor with one direction of rotation f, which is powered by the car battery and for inertia control with an electronic brake (not shown) is provided.

The component 7 has a cylindrical core 16.

on its periphery 4 elevations 17 of constant thickness evenly are arranged distributed. Each elevation is in the form of a rectangular triangle with a curvilinear hypotenuse in section educated. This triangle forms one side of the right angle with the periphery of a base of the core 16 about a little less than 90% of the periphery, and the other side of a right angle parallel to the X-X axis and ends at a small distance d from the other base of the core; the hypotenuse 18 is rotated in the direction of rotation f and forms a Ramp with a spiral control curve. The surveys 17 are alternately arranged adjacent to the two bases of the core 16, and a group of two elevations is found identical again after rotation through 180 ° around the core 16. In the direction of the circumference, each elevation is different from the next arranged in a distance interval 19, whose

The core 16 is also along its periphery its base, opposite the motor 6, in the form of a circular control cam 20, the two areas small thickness 21 diametrically opposite one another and two areas 22 of very much greater thickness diametrically opposite, and which are inserted between the two previously described. Everyone Area that extends over 90 ° is connected to the two adjacent areas by a bevel 23.

These bevels 23 are in the area of the spaces

d arranged between the adjacent elevations 17. The outer diameter of the component 20 is greater than that of the core 16 and equal to that of the elevations 17.

The frame 8 consists of a fork-shaped rod connection in U-shape, the U-bend 24 being arranged outside the base housing 3 and parallel to the bottom 4 thereof is. The two arms 25 'of the ü pass through two guide bores in the floor 4 and run parallel to the axis X-X. Halfway along the arms have a stepped deformation with an increasing spread, and they run then first to the gear 13 and to the ramp bracket 7. The deformation of an arm 25 forms an inclined one Control cam 26,

The free end of each arm 25 carries two opposing pins: an outer pin 27 which slides in a Longitudinal joint 28 is arranged for guidance in the inner wall of the base housing 3, and an inner pin 29, the extends almost to the core 16 of the component 7. Of the The diameter of the pin 29 is slightly smaller than the

(not shown), which is operated directly with a key or a pull chain of the car door, is connected. Each lever position corresponds to an end position of the frame 8. In one of these positions, as in the Figs. 1 and 2 are shown, the pins 27 at the outer end of the associated joints 28 are as large as possible Located near the cover 4; the pegs 29 are located on the inner surface of the component 20, wherein the area 26 of the component 8 in close proximity to the transmission

13 is located. In the other end position, this area 26 is in the vicinity of the bottom 4 ^a , the pins 29 being located on the gear 13.

The switch 9 is attached to the inner wall of the bottom 4 ^a; it has two fixed contacts 30, 31 and a movable contact 32 with elastic abutment on the arm 25 of the frame provided with the deformed area 26. This reverses the position of the contact 32 halfway along the frame.

The switch 10, which is attached to the base housing 3 in the vicinity of the cover 4, is of the same type as the switch 9 and is switched by its movable contact 33, the elastic on Component 20 rests and cooperates with a bevel 23 of the same to the fixed contact 34 for fixed contact 35 or vice versa.

Fig. 5 is a schematic representation of the simultaneous locking and application of the present invention Unlocking of four doors, the trunk and the closure of the fuel supply in a car. The two Device 1 for the front doors corresponding to those previously described, these two doors being manually operated Pawls are provided that can be operated directly or with a key. The other four

C.I.M. . - PH / HP 1010

Devices 1 ^a do not have a switch 9 but are otherwise identical to the drives 1.

One pole of each motor 11 is continuously connected to the negative pole of the vehicle battery 36 and the other to the mobile one Contact 33 of the switch 10 is connected. All contacts 34, like all contacts 35, are permanently connected to one another tied together. In each device 1, the contact 34 is connected to the contact 30 and the contact 35 is connected to the contact 31, just as the mobile contact 32 is connected to the positive pole of the battery. Thus, the motor 11 becomes a device 1 is supplied with electricity only when the mobile contacts 32 and 33 are coupled simultaneously with two fixed Contacts 34-30 or 35-31 interact.

In the starting position, the six contacts 33 are on their contacts 34, and the two contacts 32 on theirs Contacts 31, this position corresponding to the position shown in FIG. The bolts 29 of the frame 8 are located in two intermediate spaces 19 of the Rampenhaiterungselements 16, as shown in FIG. All locks or locks on the vehicle are on this Way, for example, locked.

If a lever or a latch is operated by a locking chain on the front door or by a key, the position of the frame 8 is thereby changed up to its outermost position according to FIG. 3; this happens without resistance on the part of the drive device 5, because the ramps 18 are completely outside the path of the bolts 2 9 is located.

Halfway along the frame, the area 26 causes the contact 32 to slide onto the contact 30. As a result the circuit of the corresponding motor 11 becomes the same like that of the five other motors 11 closed. All motors then start in the direction of rotation f while driving the

To rotate components 7. If the latter are rotated by a quarter, the bevels 23 cause the control cam of the component 2 0 the shifting of the six movable contacts 33 onto the associated fixed contacts 35, the circuit of the six motors is opened and the rotation of the six elements 7 is interrupted. You are now in the exactly symmetrical situation to that according to FIG. 5.

During this rotation, the spiral ramps 18 of the first drive did not encounter any obstacle, because the corresponding bolts 29 have already been manually brought into their opposite position according to FIG. 3 are. On the other hand, there is a bolt 29 at the base of two ramps 18 in the five other drives; the rotation of these ramps has, caused by the control cam, the two bolts in the direction of arrow g up to their opposite one Position according to FIG. 4 brought.

As a result, when the motors stop, all bolts 29 are each on the corresponding gear 13, in a gap 19, with respect to the following ramp base (taking into account the direction of rotation f), and all Locks are unlocked. It is also possible to operate one of the two manual pawls to again to trigger the corresponding functional cycle in which all bolts 29 and all movable contacts are in their off-5 pitch can be returned to all locks again to lock. Here again the position of the bolts in the spaces 19 has the consequence that the Actuation of the pawls without resistance, without manually causing a rotation of the drive device 5, and so that is possible with minimal effort.

According to FIG. 5, an optional contactor 37 for the dashboard is shown with dash-dotted lines whose help the six locks from the inside of the vehicle

stuff can be locked without manual operation of the pawls. The moving contact 38 of this contactor, which is connected to the positive pole of the battery, can take a locking position in which he with a fixed contact 39 cooperates, which is connected to all contacts 35, or an unlocked position take, in which it cooperates with a fixed contact 40, which is connected to all contacts 34. It's clear, that the actuation of this contactor triggers a cycle described above in each case.

As a modification, you can of course provide the trunk lock and / or the rear doors with an actuator 1 instead of a dependent contactor 1, and / or provide an additional actuator 1 or 1 ^a for the hood lock. In the most general sense, the invention is suitable for locking and unlocking all possible closures.

The subject of the invention is very simple and economical and yet very reliable. The shape of the Ramps 18 can easily be adapted according to the desired direction of movement of the frame 18.
