Definitions
- the present invention relates to the field of vehicle locking systems and relates to a motor vehicle lock, in particular a motor vehicle door lock, having a locking mechanism with a rotary latch and one, in particular a single, pawl, the rotary latch being able to be locked in at least one latching position by means of the pawl, a rotatable release lever , wherein the locking mechanism can be transferred from the at least one detent position into an open position by means of the release lever, and an electromotive drive unit for actuating the release lever, and wherein the drive unit is formed at least from an electric motor and a gear stage and the gear stage has an actuation lever for the actuation of the release lever.
- a challenge in the field of motor vehicle locksmiths is to further reduce the installation space required by the motor vehicle locksmiths in the vehicle.
- the weight of the motor vehicle locksmith should be reduced more and more.
- Motor vehicle locksmiths are known from the prior art, which can actuate the pawl from a latching position with an electrical opening mechanism in such a way that the locking mechanism of the motor vehicle lock can be opened/unlocked electrically.
- the release lever and the remaining actuation kinematics are often equipped with large levers, so that sufficient actuation forces can be effected via lever arms.
- the components for the pawl must Release lever and the rest of the actuating kinematics in the lock are brought into operative connection with one another, this being realized via numerous lever arrangements or cable drives.
- a motor vehicle lock is known from DE 10 2015 110 639 A1, the motor vehicle lock having a locking mechanism with a rotary latch and at least one pawl and an electric opening drive.
- the drive unit consists of an electric motor and a release lever which acts on the pawl via a lever kinematic mechanism, so that the pawl can be moved out of the latching position via the release lever and the lever kinematics.
- a disadvantage of the arrangement disclosed there is that the entire opening kinematics and thus the arrangement of the release lever and the drive unit take up a large amount of space in the motor vehicle lock.
- the electric drive is designed with an electric motor and a gear stage, with an actuating lever being arranged about a first axis of rotation and a release lever being arranged about a second axis in a first plane, with the pawl also being arranged such that it can rotate about a third axis.
- This arrangement over numerous axes requires a corresponding amount of space and is complicated to assemble.
- the object of the invention is to at least partially eliminate the disadvantages known from the prior art.
- the motor vehicle lock according to claim 1 has a locking mechanism with a rotary latch and one, in particular a single, pawl, the rotary latch being lockable in at least one locking position by means of the pawl.
- the motor vehicle lock has a release lever, wherein the locking mechanism can be transferred from the at least one locking position into an open position by means of the release lever.
- an electric drive unit is provided for actuating the release lever, the drive unit being formed at least from an electric motor and a gear stage, and the gear stage having an actuating lever.
- the pawl and the release lever as well as the actuating lever be accommodated in the motor vehicle lock so as to be pivotable about a common single axis of rotation, with at least the actuating lever and the release lever intermeshing by means of a complementary connection geometry, so that a movement of the actuating lever affects the release lever is transferrable.
- the pawl, the release lever and the actuating lever have a common axis of rotation and are accommodated in the motor vehicle lock such that they can pivot/rotate about this axis of rotation.
- the pawl, the release lever and/or the actuating lever are attached to at least one lock case.
- connection geometry designed to be complementary is preferably designed as a tooth system, it being possible for the tooth system to have one or more teeth or tooth-like geometries.
- the actuating lever or the release lever can thus preferably have external teeth and the corresponding other component can have internal teeth, or vice versa.
- the negative shape of the one connection geometry of the actuating lever or the release lever corresponds to the geometry designed to complement it.
- it could be designed in such a way that the negative shape of the flanks of an external toothing of one connection geometry corresponds in principle to the flank shape of the internally toothed component and thus to the connection geometry of the other component.
- the release lever has external teeth and the actuating lever has internal teeth, or vice versa and these teeth mesh, in particular are plugged together.
- cable constructions that have a negative impact on installation space can also be dispensed with.
- the drive unit and the actuating mechanism consisting of the actuating lever, release lever and connection to the locking mechanism, in particular the pawl, can be designed to be particularly compact.
- the at least one connection geometry can have teeth completely/all around in the area of the axis, the teeth having between one and ten teeth, preferably between 14 and 18, particularly preferably 16 teeth, the teeth interacting with corresponding essentially complementary recesses .
- an internal or external toothing is provided on the actuating lever and/or release lever.
- a so-called poka-yoke connection can be provided particularly advantageously, so that assembly can be carried out in a particularly simple and secure manner.
- at least one toothing geometry/tooth can be designed differently from the remaining teeth/toothing geometries, with a recess designed to complement the corresponding tooth/geometry in the component to be connected also being designed differently. Consequently, it is conceivable that in particular one connection geometry/one tooth is designed differently from the remaining teeth and the associated recess on the component to be connected is also designed differently and complementary to the one differing tooth/geometry.
- the release lever has a tooth with a wider tooth surface and the actuating lever has a single, larger, wider recess in which the single, wider toothing on the actuating lever can be arranged. This means that incorrect installation is almost impossible.
- the actuating lever or the release lever in the area of the axis of rotation has a collar running around it at least in sections.
- the collar is particularly preferably designed in such a way that the connection geometry, in particular toothing, at least in sections when the actuating and release lever is engaged is covered.
- this circumferential collar makes it possible to further optimize the compact construction and, moreover, the collar can form a bearing for a spring, so that the actuating lever and/or the release lever can be prestressed by means of the spring.
- the spring can thus also be arranged in a compact manner on the release lever and/or actuating lever and does not unnecessarily require additional installation space.
- the collar can cover the connection geometry, in particular the toothing, in such a way that the ingress of dirt and/or moisture can be reduced.
- the release lever can have external teeth which extend in a first direction from a first side of a substantially plate-shaped connecting section, with a bearing point for a bearing pin of the pawl being formed on the other (opposite) side of the connecting section, with in particular the bearing point is designed as a receptacle in the release lever.
- the release lever has an external toothing that interacts with an internal toothing of the actuating lever. According to the invention, however, it is also conceivable that the release lever has internal teeth and the actuating lever has correspondingly complementary external teeth. Accordingly, the release lever can also be designed in the same way as has been described above for the actuating lever.
- the release lever advantageously has an essentially plate-shaped connection section, in particular in the region of the bearing points, with the teeth, in particular external teeth, extending from the plate-shaped connection section.
- a connection point/bearing point for a bearing bolt of the pawl is formed on the release lever on the opposite side of the toothing, in particular the external toothing.
- This bearing pin is used to store the pawl on the lock case of the motor vehicle lock.
- the bearing point is also designed in particular as a receptacle in the release lever.
- the pawl and the release lever be arranged together on the bearing pin of the pawl. This further improves the compact design.
- the bearing bolt accommodates the pawl and the release lever and the release lever and the actuating lever engage in one another in a manner according to the invention.
- the release lever has one release arm, in particular a single release arm, which can be brought into or is in engagement with the pawl.
- This release arm extends in particular from the essentially plate-shaped connecting section, so that a lever arm for actuating the pawl is formed. Consequently, it can advantageously be provided that the in particular single trigger arm extends radially from the connecting section.
- axial and radial relate in particular to the axis of rotation of the pawl, the release lever and the actuating lever, so that the term axial designates in particular a direction which runs parallel or coaxially to the axis of rotation. Further, the term radial specifically denotes a direction perpendicular to the axis of rotation.
- a radial extension is to be understood in particular as an extension along or parallel to a radial direction
- an axial extension is to be understood in particular as an extension along or parallel to an axial direction.
- the release lever has a pawl receptacle.
- the pawl receptacle can be a recess in which at least part of the pawl can be arranged. It is particularly preferred if the pawl receptacle is arranged in the region of the release arm of the release lever.
- the pawl receptacle can be designed, for example, as a pocket, in which at least the pawl sections is arrangeable. A force can thus be transmitted from the release lever to the pawl in a particularly reliable manner.
- the compact geometry is further optimized as a result of which the pawl is or can be arranged at least in sections in the release lever.
- the pawl receptacle can be designed particularly advantageously in such a way that the pawl is arranged in the pawl receptacle at least in sections in a form-fitting and/or non-positive manner.
- the pawl receptacle can have a clip, locking, pinch or snap connection for the pawl, in particular a pawl arm. This not only simplifies assembly, but also enables the pawl to be securely accommodated in the release lever, with the compact design not being adversely affected.
- the pawl has at least two pawl arms, with at least one first pawl arm having a latching surface for engagement with the rotary latch and with a second pawl arm being arranged at least in sections in or on the release lever, with the two pawl arms in particular being radially separated from the axis of rotation extend in substantially opposite directions.
- the pawl has only two pawl arms, the first pawl arm being provided for locking with the rotary latch and the second pawl arm being arranged at least in sections in the release lever as described above, so that the pawl is of compact design .
- the second pawl arm with the geometry of the trigger arm and an actuating arm of the actuating lever is arranged in an overlapping manner in the motor vehicle lock. It is thus possible according to the invention that only the ratchet arm for locking with the ratchet extends in the opposite direction to the second ratchet arm.
- the second pawl arm, the The release arm and an actuating arm of the actuating lever each extend in a common direction opposite thereto.
- the actuating lever in particular an actuating arm of the actuating lever, at least partially encompasses and/or covers the gear stage, in particular a gear wheel of the gear stage.
- the actuating lever is essentially U-shaped or curved and that the actuating lever encompasses the gear stage, in particular a gear wheel of the gear stage.
- the operating arm or operating lever essentially has a shape with the two end points of the lever or arm being located on either side of the gear wheel. Accordingly, this configuration allows the actuating lever and the gear stage to be of particularly compact design, since at least a sectional overlap ensures that installation space is not unnecessarily wasted.
- the actuating lever and the drive unit ie including the gear stage
- the drive unit with the gear stage and the actuating lever preferably also lock electronics and/or power supply
- the drive unit with the gear stage and the actuating lever are arranged at least in sections in a drying area of the motor vehicle lock housing and the locking mechanism and at least sections of the release lever are arranged in a damp area of the motor vehicle lock.
- a previously explained seal is provided between the individual components release lever, actuating lever and pawl. It can thus be achieved that a sealing/sealed connection between the different lock housing parts and the connection of the components pawl, release lever and actuating lever can be achieved.
- the locking mechanism at least having a pawl and rotary latch, is particularly easy to unlock d.
- H. is designed to be easy to open or open with little effort.
- the rotary latch has a locking element movably mounted on the rotary latch, the locking element being rotatably arranged at least in sections in the rotary latch and/or on the lock case or the lock housing.
- the blocking element can in particular roll off at least in sections on the rotary latch and/or the pawl.
- Main catch and / or first catch is particularly smooth allows.
- the pawl is acted upon by the release lever with a release force in such a way that first the blocking element moves or rolls in the rotary latch in such a way that particularly low opening forces are required.
- the lever kinematics of the actuation can thus also be made smaller and thus be made compact.
- a lock When speaking of a lock for a motor vehicle within the scope of the invention, this includes all locking systems that fix a movable part in a position relative to the motor vehicle.
- a lock can be arranged, for example, in a side door, a sliding door, a flap, a cover, but also, for example, in a rear seat bench. Everywhere where moving parts are used by means of a locking system consisting of a locking mechanism with at least one pawl and a rotary latch.

- 3B schematically shows the release lever of an embodiment of a motor vehicle lock according to the invention
- 3C schematically shows the pawl of an embodiment of a motor vehicle lock according to the invention.
- FIG. 4 schematically shows an embodiment of a motor vehicle lock with a wet and dry area according to the invention.
- FIG. 1A shows a possible exemplary embodiment of a motor vehicle lock 10 according to the invention, having a lock housing 30, which is shown here only in part, further with a locking mechanism 11 comprising a pawl 13 for locking the rotary latch 12 in at least one latching position I, in particular a main grid I and /or a pre-grate position.
- a lock holder 40 is fixed by the rotary latch 12 in such a way that a movable part of a vehicle, for example a motor vehicle door, is held in a closed position and blocked against unintentional opening.
- the pawl 13 has a latching surface 13.3 which, in the latching position I, is in engagement with a blocking element 14 of the rotary latch 12 and thus blocks the rotary latch 12 from moving in the opening direction.
- the blocking element 14 is movably, in particular pivotally mounted, in the rotary latch 12 and/or a lock plate/lock case (as illustrated by a combination of FIGS. 1A and 1B).
- the pawl 13, in particular the latching surface 13.3, is structurally designed or has a geometry such that the pawl 13 has a closing tendency. According to the invention, a neutral design can also be provided.
- the pawl 13, in particular the locking surface 13.3, is geometrically designed in such a way that the pawl 13 cannot be deflected/unlocked in the opening direction independently, in particular due to pressure from the rotary latch 12.
- the force exerted by the rotary latch 12 on the pawl 13 thus runs past the pawl axis in such a way that no opening moment is generated, but rather the pawl 13 is pushed in the direction of the rotary latch 12 .
- the pawl 13 can be rotated about the axis of rotation R, the pawl 13 being arranged/mounted on a bearing pin 27 for this purpose.
- the pawl 13 in the exemplary embodiment shown has a first pawl arm 13.1 and a second pawl arm 13.2.
- the first pawl arm 13.1 and the second pawl arm 13.2 extend in diametrically opposite directions from the axis of rotation R or the bearing pin 27.
- the locking surface 13.3 is arranged for a Ver most with the locking element 14 and thus the rotary latch 12.
- the pawl 13 is arranged on the release lever 15 on the second pawl arm 13.2.
- a pawl receptacle 15.2 is formed in the release lever 15, in which the second pawl arm 13.2 is arranged, in particular held in a non-positive and/or positive manner.
- the release lever 15 is also rotatably mounted on the same axis of rotation R as the pawl 13 . This also applies to the actuating lever 19, which is also arranged to be rotatable about the axis of rotation R. Release lever 15 and actuating lever 19 have a connection geometry 20 according to the invention
- the motor vehicle lock 10 also has an electromotive drive unit 16 comprising an electric motor 17 and at least one gear stage 18 .
- the electromotive drive unit 16 is used to open the locking mechanism 11, in particular to lift the pawl 13 by means of the release lever 15 with the interposition of the actuating lever 19.
- the electric motor 17 drives a worm on the output shaft of the electric motor 17, the worm working by means of teeth on a toothed wheel/worm wheel 18.1 and driving it in rotation.
- the gear 18.1 is designed in the figures as a spur-toothed worm wheel 18.1.
- an evoloid toothing is also conceivable.
- a substantially ramp-shaped (worm) contour 18.3 is formed around its axis of rotation on the worm wheel 18.1, with which the contact surface 19.2 of the actuating lever 19 comes into contact and rotates it about the axis of rotation R.
- the contact surface 19.2 of the operating lever 19 consequently moves along the Contour 18.3 when the worm wheel 18.1 rotates, causing the actuating lever 19 to rotate about the axis of rotation R.
- the actuating lever 19 and the release lever 15 have a complementary connection geometry 20 so that a movement of the actuating lever 19 is transmitted to the release lever 15 .
- the rotary movement of the actuating lever 19 brought about by an electric motor is thus transmitted to the release lever, so that the release lever 15 is moved about the common axis of rotation R of the actuating lever 19 , release lever 15 and pawl 13 .
- the release arm 15.1 of the release lever 15 has a pawl receptacle 15.2, in which the second pawl arm 13.2 is arranged, so that the pawl 13 can be rotated about the axis of rotation R/the bearing pin 27.
- FIG. 1B shows the motor vehicle lock in an open position II, in which the pawl 13 is lifted off the rotary latch 12 and consequently the latching surface 13.3 of the pawl 13 is no longer in blocking engagement with the locking element 14 of the rotary latch 12.
- the blocking element 14 moves with it at least in sections due to its bearing and is thus also lifted off the rotary latch 12 at least in the region of the latching surface of the rotary latch 12 .
- This movement can now turn the closing tendency into an opening tendency, so that the pawl 13 is pushed further in the direction of the opening position II due to the force acting on the pawl from the rotary latch 12 and opening/unlocking the locking mechanism 11 is supported/facilitated.
- FIG. 1B now shows the deflected blocking element 14.
- the blocking element 14 is mounted in the catch 12 and preferably additionally on a lock case.
- a lock case For a in Figs. 1A and 1B shown bolt may be provided, which can also be stored in the lock case.
- Figs. 1A and 1B clearly show the compact structure of a motor vehicle lock made possible by the invention.
- the pawl 13 and the release lever 15 as well as the actuation lever 19 are accommodated in the motor vehicle lock 10 so that they can pivot about a common axis of rotation R, with at least the actuation lever 19 and the release lever 15 engaging in one another by means of a complementary connection geometry 20, so that a movement of the actuation lever 19 onto the release lever 15 to open / unlock the locking mechanism 11 is transferrable.
- the release lever 15 is arranged between the pawl 13 and the actuating lever 19 on the axis of rotation R.
- Pawl 13, release lever 15 and actuating lever 19 are nested in a broader sense or at least partially plugged together.
- the pawl 13, the release lever 15 and the actuating lever 19 are connected to one another by means of at least one, preferably several, plug connection or connection geometry 20. It is particularly advantageous for the pawl 13 to be plugged into one another in the manner described with the release lever 15 by means of the plug-in connection of the pawl arm 13.2 and the pawl receptacle 15.2, and the release lever 15 by means of the connection geometry 20 to be described further below. In particular, this configuration enables the compact structure.
- the bearing point 26 can be designed as a recess or indentation, so that the bearing pin 27 and/or at least sections of the pawl 13 can be arranged in/on the release lever 15 .
- a collar 23 is formed on the release lever 15 in Fig. 1 B, which can also contribute to the fact that the Bearing 26 and / or the storage of the pawl 13 is protected on the bearing pin 27 from external environmental influences or the release lever 15 gives more mechanical stability overall.
- Figs. 2A and 2B show the actuating mechanism and the pawl 13 in a further perspective.
- the connection geometry 20 of the release lever 15 and the actuating lever 19 can be seen clearly in FIG. 2A.
- the nested/plugged together design of the components 13, 15 and 19 on a common axis of rotation R can be seen in FIG. 2A. It can be seen that the compact structure can also be improved by arranging the gear wheel/worm wheel 18.1 at least in sections parallel to the axis of rotation R, so that the space required in the direction of the axis of rotation R can be further reduced.
- connection geometry 20 in FIG. 2A has teeth 21 on the release lever 15 which are arranged/inserted in a correspondingly complementary recess on the actuating lever 19 .
- the teeth can also be formed on the actuating lever 19 and the recess in the release lever.
- the release lever 15 and the actuation lever 19 can engage in one another due to the complementary connection geometry 20 , so that a movement of the actuation lever 19 can be transferred to the release lever 15 .
- the bearing pin 27, the pawl 13, the release lever 15, a release lever spring 15.3 and the actuating lever 19 are arranged along the axis of rotation R.
- the components 27, 13, 15, 15.3 and 19 are at least partially nested or plugged into one another, as a result of which a compact structure is made possible.
- the release lever spring 15.3 can spring-bias the release lever in such a way that it is acted upon in the opening direction or in the closing direction.
- the spring force can therefore act on the release lever 15 and due to the connection of the release lever 15 and the pawl 13 in the direction of the rotary latch 12 / detent position I or away from the rotary latch in the direction of the opening position.
- the Release lever 15 and thus the pawl 13 are acted upon in the direction of the latching position and thus facilitates the engagement of the pawl 13 in the latching position of the rotary latch 12.
- the release lever spring 15.3 can bear against the release lever 15 on the one hand and on the lock housing or a lock case on the other .
- the release lever spring 15.3 and the release lever 15 are designed in such a way that the release lever spring 15.3 is mounted on the release lever and the legs of the release lever spring 15.3 designed as a double leg spring can be supported on the release lever and on the lock housing or lock case.
- One leg of the spring 15.3 engages in a receptacle on the release arm 15.1 of the release lever 15.
- the windings of the release lever spring 15.3 are consequently arranged on the release lever 15 in such a way that the installation space can be kept compact.
- the release lever 15 can preferably have a spring seat on which the release lever spring 15.3, in particular the coils, is mounted.
- the release lever 15 in the exemplary embodiment shown is designed with a release arm 15.1, with the release arm 15.1 being angled.
- the release arm 15.1 is arranged at right angles to the rest of the release lever 15 in FIG. 2A.
- the pawl receptacle 15.2 is formed on the angled release arm 15.1, in which a second locking arm 13.2 of the pawl 13 is arranged/inserted. Accordingly, a movement of the release lever 15 can be transmitted to the pawl 13, while at the same time a compact structure is realized. This movement then enables the first ratchet arm 13.1 to be lifted off the catch or the blocking element.
- the pawl 13 is in the exemplary embodiment shown with the second pawl arm 13.2 in the pawl receptacle 15.2 of the release arm 15.1 arranged by the release lever 15.
- the pawl arm 13.2 is held at least in sections in a non-positive and/or positive manner in the pawl receptacle 15.2.
- the release lever 15 is prestressed by means of a release lever spring 15.3, with the spring 15.3 preferably prestressing the release lever 15 and thus the pawl 13 in the direction of the catch.
- the release lever spring 15.3 is designed as a double leg spring and is mounted with one leg on the release lever arm 15.1 and with another leg on the lock housing or the lock case.
- the pawl 13 also shows a bearing bolt receptacle 13.4, with the bearing bolt 27 being received therein so that the pawl 13 can rotate around it.
- the pawl 13 has buffer pockets 13.5.
- the buffer pockets 13.5 serve as stop buffers for contact with the rotary latch and/or the lock case or lock housing.
- FIG. 3A shows the actuating lever 19 in detail.
- This has a U shape.
- the U-shape makes it possible for the actuating lever 19 to at least partially encompass the worm wheel 18.1 with its actuating arm 19.1, as a result of which the compact design is further optimized.
- the recess 22 can be arranged on one side of the worm wheel and the contact surface 19.2 on the other side of the worm wheel, on which the ramp-shaped contour is formed.
- the recess 22 and thus the receptacle for the teeth of the release lever are arranged at one end of the actuating arm 19.1, with the contact surface 19.2 at the other end of the actuating arm 19.1 for interaction with the worm wheel 18.1, in particular the contour of the worm wheel 18.1.
- the recess 22 is here as a receiving geometry for the external toothing of the release lever is formed. Consequently, the recess 22 has several indentations for a multi-tooth geometry. In the present case it is the case that the negative shape of the flanks of the external toothing of one connection geometry on the release lever corresponds to the flank shape of the internally toothed operating lever 19 and thus the connection geometry of the other component.
- the operating lever 19 and the release lever 15 can engage in one another due to the complementary connection geometry 20 so that a movement of the operating lever 19 can be transferred to the release lever 15 .
- a poka-yoke recess 22.1 is provided, so that the release lever 15 and the actuating lever 19 are prevented from being incorrectly assembled/connected incorrectly.
- the poka-yoke recess 22.1 is larger/wider than the remaining recesses/indentations of the recess contour 22. A wider tooth on the release lever, the poka-yoke tooth, can therefore only be inserted into the poka-yoke recess 22.1 . Incorrect assembly is thus excluded.
- the actuating lever has material recesses, as a result of which the weight of the lever 19 can be reduced.
- the actuating lever 19 has reinforcing ribs 19.4 in the area of the actuating arm 19.1.
- the release lever 15 has a release arm 15.1 which is arranged essentially at an angle, preferably at right angles, to the remaining release lever 15.
- the release arm 15.1 has a pawl receptacle 15.2 in which the pawl is preferably arranged/received without play.
- the external toothing 24 is designed for the common connection geometry of at least the actuating lever and the release lever 15.
- the external toothing is designed as a multi-tooth geometry and has a poka-yoke tooth 24.1 in the exemplary embodiment shown.
- the toothing 24 can be referred to as a quick-release axle and can be inserted into the corresponding recess in the operating lever. Consequently, the operating lever 19 and the release lever 15 engage by means of a complementary connection geometry 20 into each other, so that a movement of the actuating lever 19 can be transferred to the release lever 15 .
- a collar 23 is formed around the external toothing 24 or the quick-release axle formed therewith, which can serve, for example, as a spring seat for the release lever spring.
- the release lever 15 also has a substantially plate-shaped connecting section 25 . On one side of the connecting section 25 extends the external toothing 24 / full-floating axle, with a bearing point 26 being formed on the other side of the connecting section 25 . At this bearing point 26, for example, a bearing pin of the pawl can be accommodated at least in sections. This also has a positive influence on the compact design.
- the collar 23 encloses the connection geometry of the release lever 15 and the actuating lever 19. B.
- the cylindrical collar 23 of the release lever thus encompasses or covers in particular a likewise cylindrical section of the recess 22 on the actuation lever 19.
- the toothed connection geometry of the release lever and actuation lever is thus encased/enclosed overall and thus gives it more stability and protection from external environmental influences.
- the pawl 13 has two pawl arms 13.1, 13.2, a first pawl arm 13.1 having a latching surface 13.3 for Ver most with the catch 12 and a second pawl arm 13.2 at least partially in the release lever 15 can be arranged.
- the two pawl arms 13.1, 13.2 extend radially from the bearing seat 13.4 in substantially opposite directions.
- the pawl 13 has at least one actuating contour 13.6 for a switch or sensor.
- an extension can be seen which can be plugged into the pawl receptacle of the release lever.
- FIG. 4 shows an embodiment according to the invention of a motor vehicle lock 10 having a lock housing 30 with the shown Wet room 32 and dry room 31. These are arranged essentially at right angles to one another.
- the drying room 31 encloses most of the operating mechanism. Namely, the electric motor drive 16 with the electric motor 17 and the gear stage 18, comprising the worm 18.2 and the worm wheel 18.1, are accommodated in the drying room 31.
- the actuating lever 19 is arranged in the dry space 31 and has an interface to the wet space 32 .
- a seal 19.5 is arranged on the operating lever 19, which seal serves to seal the dry space 31 from the wet space 32 in the area of a passage for the trigger or the operating lever 19.
- the axis of rotation runs through the passage from the dry to the wet space 32.
- the connection geometry according to the invention is preferably also arranged in the area of the passage and is sealed off by means of the seal 19.5.
