The innovation relates to a motor vehicle deer lock with a lock latch on the outside of the lock housing, with the non-rotatable on a common bearing axis a lock housing inner side locking plate is connected, which cooperates with a pawl which through one from both the inside of the vehicle via one The inside door handle as well as from the outside of the vehicle via an actuator of a lock cylinder The release lever can be actuated, either in an operating pawl that entrains the pawl or in a pawl unaffected leaving inoperative position is movable.

In the case of electric vehicle door locks, the initially It is known that the genus described with the Locking plate cooperating pawl from both the interior of the vehicle over the inside door handle as well as from the

7406360 09/04/75

Can be actuated from the outside of the vehicle via a lock cylinder is. The pawl is actuated via a so-called release lever. This can be in the shooting case be moved so that it is once brought into a position, the pawl being taken and dasit the locking plate is released together with the lock latch. At the other, the release lever can also be in one position move in which there is no entrainment of the pawl. This position can be used with the locked or secured Designate the lock position, i.e. when the lock cylinder is in the closed state

In such a lock structure, it is essential that the release lever is designed so that it has on the one hand a cooperating with the pawl effective area and on the other hand is designed so that the firing cylinder or an actuating member can attack it to a Bring about movement of the release lever, to be able to.

This is due to the fact that the various types of motor vehicles not only include the motor vehicle lock , but also the

7406360 09/04/75

and the position of the lock cylinder in the vehicle door motor vehicle by always pbedingt at different points are, it is imperative required in each case that the motor vehicle door locks have a structurally to the position of the lock cylinder in the vehicle door, that is form-fitting and long-matched trip lever. For a manufacturer of motor vehicle door locks, this means that he must have different locks ready for the various types of motor vehicle, in particular with regard to the design of the actuating lever.

Based on this diversity of types, there is now the technical task of the present innovation in not only to simplify a motor vehicle door lock in terms of its structure and to functionally improve, but also unify, in order to make it more universal for practical use Application to design cheaper.

The goal of the innovation is achieved in an advantageous manner by the fact that the one emanating from the lock cylinder and actuating member guided in sighting of the release lever depending on the position of the lock cylinder

This can be described as a decisive advantage if one takes into account that "with the previously known structure there at least the triggering fog" and sometimes even further levers for the puncture design had to be changed in order to check the age of the closing cylinder. earth · Jettt entetent a τοη of the basic form and rom the basic structure ner Einheltlicnea Senlofi «because« old the power fan free door Senliefi cylinder through, a variable actuating member is coupled *

Because the aea variable actuating member engages a special lever in the lock housing * a pick-up lever, the actual structure of the release lever remains unaffected in its actual basic form can attack as well as the release lever on the same lever, then there is a particularly favorable actuation for the release lever, which is essentially movable in a vertical plane. This is because it succeeds for the first time in the adjustment movement of the release lever

Precisely this measure, which proposes the hiring, urges practice to have a further benefit, so that in addition to the advantage of the now uniform lock structure for different types of vehicles with different arranged lock cylinder now also the operating function, in particular the movement of the release lever by its linkage to a swiveling drive lever

7406360 09/04/75

is improved. Both parts together cause a lock to be disfigured, which is one of the greatest in practice represents a viable solution.

In a practical implementation of the object of fire, an advantageous embodiment can be seen when it is received at its end by a bearing point on the lock housing side, while at the other end it has a fixed point of attack for the actuating element and finally in the area in between with a additional articulation point for the release lever is provided.

If you use the take-away lever to which both the Actuating member as well as the Auslösehehel engages, rotatably mounted at one end on a bearing axis, then "particularly favorable operating conditions arise because the movement of the drive lever from the point of attack dfe3 actuator from a favorable lever arm he follows. This means that the release lever can be actuated particularly easily.

The pure construction of the drive lever

can be designed in such a way that it is mounted on its own bearing axis outside of the locking plate on the inside of the lock housing and is cranked in a substantially Z-shape outside of its bearing point in the longitudinal direction up to approximately the level of the release lever, in this area a clutch diaphragm. for Anl e LIMITATION of the release lever and comprises in connection with this one to the lock towards the interior bent at right angles to the plane of the entraining lever web forms, having a coupling opening for the connection of the actuator.

This solution is an optimal design for the reason that it was done with a small amount of material a functionally highly effective component is achieved, which at a very specific point is both the point of attack for the actuator from the lock cylinder as well as the articulation point for the release lever carries.

Based on this point of attack for the actuator at a very specific point on the drive lever it turns out that not only the release lever, but also the drive lever now for all types with each other

can be carried out uniformly. All type-dependent Difference * related to the position of the lock cylinder to the Xraffr vehicle Q deer lock are due solely to the variable Actuator bridged reliably without affecting the actual lock function in any way will.

It is in waiter-er advantageous design of the The subject of the hiring, however, is also possible, the point of attack for the actuating member through a coupling breakthrough Form directly on the release lever. Here, too, the same system is followed, namely a uniform one To leave the lock structure for different types of vehicles, whereby the point of attack for the Actuator is always provided at the same point on the release lever. In such a case then from here through the variable actuator the required Compensation based on the position of the lock cylinder it acts. This solution also has the advantage that, in turn, the release lever is moved by hinge points is transmitted, so that in turn pivoting motion functions can be executed, so that even with such

Embodiment that "with pure slide movements known disadvantages do not appear.

In summary, the innovation has succeeded in creating a uniform lock type for the first time for s & hi i ofizyl jLnflea? to be used on motor vehicle doors, so that significant advantages of the subject of hiring can be seen in the standardization on the one hand and in the improvement of functions on the other hand and finally in the more universal applicability. In addition, the actual handling of such a lock is decisively improved by the improved actuation function, in particular for the adjustment of the release lever.

In addition, an embodiment of the subject of the hiring is shown in the accompanying drawing, which reproduces an interior view of such a motor vehicle door lock, with a possible location of a Lock cylinder is shown with and this is connected to the drive lever via an actuator

is initially with 10, 11 an angular cross-section, two-legged lock housing designated. Within the Lock housing cheek 10 are on a common bearing axis 12 both a locking plate 13 on the inside of the lock as also a - not shown - lock latch on the outside of the lock rotatably mounted together. With the locking plate, a pawl 14 cooperates, which around a own bearing axis 15 is mounted within the Schißgehäuses. The pawl 14 is through with the locking plate 13 a common spring 16 is loaded. The pawl 14 has an actuating arm 14a, which from the pivot point the pawl is guided from so in the lock housing that in an operating position of a release lever 17 a Taking this pawl is possible. Such a position is shown in the drawing, that is, if the release lever 17 is moved in the direction of the arrow "A", then a driver member 17a of the release lever lies in front of the Actuating arm 14a, so that the pawl is entrained and thus the locking plate is released.

The release lever 17 is longitudinally guided on the one hand over the axis in the lock housing and is over at one end a Gtelenkachse 18 articulated on a driving lever 19,

which itself is mounted on a bearing axle 20. In addition, the release lever 17 is on another Lever 21, which is rotatable in the area of the bearing axis 22 is stored, connected via a driver 23, so too the release lever of another, this lever 21 actuating {Door handle or the like. is actuatable.

Outside of its bearing axis 20, the driving lever 19 is initially equipped with an essentially Z-shaped Y * r offset 24, whereby it is guided approximately up to the level of the release lever 17. It rests under the release lever. Outside the hinge point 18, the drive lever is bent at right angles to the Schloßgehäusei i mern to form a web 25 and has a coupling opening 26 within this web, to which an actuating member 27 can be attached at one end. With its other end, the actuating member 27 engages the lock cylinder 28 or a transmission lever 29 of the same.
