Description

The invention relates to a locking arrangement for a vehicle sliding door having the features of the preamble of claim 1.

Vehicle sliding doors are known from the prior art, in particular from the field of public transport vehicles, which can be brought into a locked and unlocked state by actuating the rotary latch. The locked state corresponds to the situation of a completely closed vehicle sliding door and the unlocked state to the situation of a vehicle sliding door which has in any case performed a partial opening movement. This can also be described as a partially open condition. This partial opening movement is generally carried out essentially perpendicularly to the plane defined by the vehicle sliding door or its door leaf. From this unlocked state, a further sliding movement can then be carried out essentially in the plane defined by the vehicle sliding door, but this then no longer changes the state of the rotary latch. The transition to the locked state then takes place in the opposite direction. Such a rotary latch, which is known per se from the prior art, regularly comprises not just a single pivotable element, but an arrangement of interlocking devices, the position of which then corresponds overall to an unlocked or locked state of the rotary latch. Consequently, here and in the present case, the term rotary latch means this arrangement as a whole, which arrangement also includes other separately movable parts and in particular a locking bolt or the like. may include.

For the intended operation of the vehicle sliding door, a door drive is provided, which drives the rotary latch to move between its unlocked state and its locked state. In addition, there is also the possibility of unlocking the rotary latch by means of a manual emergency release and thus without the help of the door drive in order to open the vehicle sliding door. A deflection rocker is provided for this purpose, in which a pivotable actuating lever can be actuated via a pulling element and which actuating lever then brings the rotary latch from the locked state into the unlocked state, for example via a Bowden cable.

Such a deflection rocker for a rotary latch of a vehicle sliding door for a public transport vehicle is in Patent specification EP 2 486 207 B1 discloses which patent is considered closest to the present invention. Here and below, the term deflection rocker is understood to mean not only that pivotable rocker element or that actuating lever in the narrower sense, which acts on the rotary latch, but the arrangement as a whole, which serves to transfer the actuation of the emergency release to the rotary latch.

In addition to the emergency release just described, further functionalities can be provided in connection with the rotary latch. Thus, the vehicle sliding door often has additional devices which enable the transition between the closed and the partially open state of the vehicle sliding door. This usually involves one or more further rotary latches or swivel arms. Since the rotary latch described above and the first one present here is regularly arranged above the vehicle sliding door, these further rotary latches or swivel arms are regularly offset laterally in the plane of the door leaf with respect to the first rotary latch and vertically offset with respect to the first rotary latch and in particular further down than the first rotary latch arranged. For this reason, such rotary latches are also referred to as lateral rotary latches, in contrast to the rotary latch that is articulated via the articulation device. In this way, the force for the transition between the closed and the partially open state of the vehicle sliding door acts not only at the upper end of the vehicle sliding door, but can advantageously also be exerted in a lower and/or lateral area of the vehicle sliding door.

Another function is the possibility of deactivating the vehicle sliding door. When the deactivation is activated, which must be carried out regularly by exerting manual force and without the help of a motor, the rotary latch is held in the locked state. Depending on the desired structural variant of the vehicle sliding door, such a shutdown can potentially be canceled by an emergency release.

And finally, it is regularly provided that such an emergency unlocking from the inside should not be possible even when the vehicle with the vehicle sliding door is in motion.

The functionalities just described are desired in different combinations and constellations depending on the vehicle or depending on the vehicle sliding door. In the prior art, these different variants are implemented in such a way that different and separate components, all of which are intended to act on the rotary latch, are to be actuated with the rotary latch or are intended to influence the action on the rotary latch, to form a lever arrangement that is also spatially extended be joined together in a corresponding force effect chain. Due to the large number of possible variants, these are regularly ad-hoc constructions, which are characterized by a low structural transferability to other variants of vehicle sliding doors. Each additional function leads to an increase in size and complexity, while the size of such a structure can already correspond to almost the entire width of the door leaf.

From the EP 1 516 984 A2 as well as from the EP 2 165 869 A1 locking arrangements of a vehicle sliding door with a lockable and unlockable rotary latch for the vehicle sliding door are also known, which locking arrangements comprise a large number of different levers which are arranged separately from one another and take up installation space.

Based on this prior art, the object of the invention is to further develop and improve a known deflection rocker for actuating a rotary latch of a vehicle sliding door or such a vehicle sliding door with such a deflection rocker so that different variants with regard to the function of the deflection rocker are structurally simpler and with less Space requirements can be implemented.

The invention is defined by the appended claims.

The invention is based on the finding that a configurable combination of different functionalities can be implemented on a single space-saving device by the actuating lever being arranged firmly following the rotary latch. In contrast, according to the approach from the prior art, this actuating lever should only have an unlocking effect on the rotary latch, so that a coupling is only provided for such an actuation. Such a conditional coupling is also provided for the other functionalities in the prior art, so that they can be triggered independently of one another. Since the actuating lever now firmly follows the rotary latch according to the invention, the different mechanical switching and actuating functions of the other functionalities can specifically attack the actuating lever of the deflection rocker instead of having to act on the rotary latch in a space-consuming manner, as in the prior art.

A corresponding locking arrangement according to the invention with a deflection rocker in the basic version—like a basic module—can then be supplemented by elements for additional functions, with these supplements not resulting in any significant increase in the space required. In this way, the construction of surrounding parts and components can also be geared to the space requirements and the dimensions of this basic deflection rocker, independently of the functionality variant desired in each case. As a result, a unit that is standardized in terms of its dimensions can be provided, which can be supplemented with the desired functions while maintaining its dimensions.

The locking arrangement according to the invention with a deflection rocker is used to actuate a rotary latch of a vehicle sliding door. This vehicle sliding door is preferably the sliding door of a public transport vehicle and in particular the sliding door of a rail vehicle or a bus. The rotary latch preferably comprises a toggle lever arrangement for holding the rotary latch in the locked state when a dead center of the toggle lever arrangement is exceeded. In particular, the dead center is exceeded when locking the rotary latch from the unlocked state. In the present case, the term “rotary latch” means an entire rotary latch arrangement. Correspondingly, the concept of a rotary latch arrangement could also be used instead of a rotary latch. In the present case, the rotary latch arrangement is a rotary latch in the narrower sense—that is, the specific one pivotable device for receiving a locking bolt or the like. - out.

The locking arrangement according to the invention with a deflection rocker comprises an actuating lever for moving the rotary latch, which actuating lever can be moved between a locking position for locking the rotary latch and an unlocking position for unlocking the rotary latch, and an emergency release lever, which emergency release lever engages with the actuating lever to move the actuating lever into the unlocked position are bringable. The emergency release lever can therefore be brought into engagement with the actuating lever in such a way that the actuating lever is moved into the unlocked position. This movement of the release lever in turn unlocks the catch. Both a device for emergency unlocking from the outside and a device for emergency unlocking from the inside are regularly provided in a vehicle sliding door that is relevant here, which is why the deflection rocker according to the invention preferably comprises a further, and thus two, emergency unlocking lever.

The locking arrangement with a deflection rocker has an articulation device which is firmly connected to the actuating lever and via which the actuating lever can be coupled to the rotary latch, so that the rotary latch and the actuating lever follow their movement reciprocally. In other words, in the case of this coupling, the rotary latch and the actuating lever are rigidly connected to one another with regard to their respective movement between the locking position of the actuating lever—corresponding to the locked state of the rotary latch—and the unlocking position of the actuating lever—corresponding to the unlocked state of the rotary latch. The position of the actuating lever is then always an image of the state of the catch and vice versa.

The locking arrangement according to the invention with a deflection rocker is characterized in that the emergency release lever and the actuating lever are pivotably mounted on a common pin. If there is another emergency release lever, it can also be pivoted on the common pin. In this way, a particularly space-saving arrangement is given.

In particular, it can be the case that the common pin divides the operating lever into a first operating lever swivel arm and a second operating lever swivel arm, with this subdivision preferably taking place essentially in the middle. This then means that the first actuating lever pivot arm is essentially as long as the second actuating lever pivot arm is, in each case related to the pin. In principle, this variant allows both pivoting arms of the operating lever to be used for operating the rotary latch or other devices.

A further preferred embodiment of the locking arrangement according to the invention with a deflection rocker is characterized in that the rocker arrangement has a first pulling device for actuating the emergency release lever, which pulling device is attached to a first swivel arm of the emergency release lever. In particular, the pulling device can be a Bowden cable, with the core of the Bowden cable being attached to the first swivel arm of the emergency release lever.

Here it is further preferred that the common pin divides the emergency release lever into its first swivel arm and its second swivel arm. This subdivision is preferably carried out essentially in the middle, ie in such a way that the first pivoting arm and the second pivoting arm have essentially the same length in relation to the common pin. Such a subdivision of the emergency release lever makes it possible to arrange a pulling device for actuating the emergency release lever in such a way that it is attached to the second swivel arm. Since the direction from which the pulling device or the Bowden cable is routed to the deflecting rocker or to the emergency release lever is specified when the deflection rocker is installed, the pulling device or the Bowden cable can be attached to the emergency release lever from both directions without going to the other side of having to be guided by the deflection rocker.

According to a preferred embodiment of the locking arrangement according to the invention with a deflection rocker, it is provided that the rocker arrangement has a further pulling device for actuating a further emergency release lever, which further emergency release lever can be brought into engagement with the actuating lever for moving the actuating lever into the unlocking position and which further pulling device on a first Pivot arm of the other emergency release lever is attached. The additional pulling device can be an additional Bowden cable, the core of the additional Bowden cable being attached to the first swivel arm of the additional emergency release lever. Here, too, provision can be made for the common pin to hold the additional emergency release lever preferably subdivided essentially in the middle into its first swivel arm and its second swivel arm. This subdivision, which is essentially in the middle, is to be understood in the same way as that of the first emergency release lever. This now makes it possible to fasten the other pulling device to the other emergency release lever without having to guide the other pulling device around the deflection rocker.

Especially in combination with the preferred variants relating to the first emergency release lever, this allows the actuating lever to be actuated by a pulling force from two opposite directions with the same effect. This is advantageous because the two emergency release devices are regularly arranged on opposite sides of the deflection rocker.

A further preferred embodiment of the locking arrangement according to the invention with a deflection rocker is characterized in that a first tensile force exerted by the pulling device for actuating the emergency release lever is aligned essentially in the opposite direction to a second pulling force exerted by the further pulling device for actuating the further emergency release lever. This corresponds to the variant already described above, according to which the two traction devices are brought up to the deflection rocker according to the invention from different sides of the latter. Here it can also be the case that the first tensile force exerts a torque on the emergency release lever in a direction identical to the torque exerted on the further emergency release lever by the second tensile force. It can also be the case that the first swivel arm of the emergency release lever is arranged essentially opposite the first swivel arm of the other emergency release lever in relation to the common pin.

A preferred embodiment of the locking arrangement according to the invention with a deflection rocker is characterized in that the deflection rocker has a free-pull device which can be brought into an engaged state and into a free-pull state, wherein in the engaged state a force effect chain from the pulling device to the emergency release lever for actuating the emergency release lever is closed and in the Freizugstaat the force effect chain is open from the traction device to the emergency release lever, so that the traction device runs free. In this way, an emergency release can be prevented from being triggered by the emergency release lever—regularly by an emergency release triggered from inside the vehicle. It is further preferred here that the release device can be switched electrically between the engaged state and the release state and the release device is always in the engaged state when there is no current. This embodiment is based on the idea that preventing the emergency unlocking from the inside in this way only makes sense when the vehicle with the deflection rocker is in motion and is therefore energized. If the power fails for any reason, the vehicle also comes to a standstill and an emergency unlocking from the inside is possible again.

Furthermore, a preferred embodiment of the deflection rocker provides that the release device is arranged on the emergency release lever and is specifically attached to the emergency release lever, so that the release device is moved with the emergency release lever when the emergency release lever is actuated. It is true that this increases the energy required to actuate the emergency release lever due to the additional mass of the release device. However, since such an actuation of the emergency release lever does not correspond to a regular operating case - but is only provided for comparatively rare emergency releases - this potential disadvantage is eliminated by the saving of a separate attachment.

According to a preferred embodiment of the locking arrangement according to the invention with a deflection rocker, it is provided that the actuating lever has a driver pin and that when the emergency release lever is actuated, in particular by the pulling device, the emergency release lever engages with the driver pin in such a way that the actuating lever is moved into the unlocked position . This represents a preferred solution for transferring actuation of the emergency release lever to actuation of the actuating lever. It is also preferred that when the further emergency release lever is actuated, in particular by the further pulling device, the further emergency release lever engages with the driver pin in such a way that the actuating lever is moved into the unlocked position. A single driver pin can thus be provided for actuation by both emergency release levers.

A preferred embodiment of the locking arrangement with a deflection rocker is characterized in that the rocker arrangement has a rigid support arrangement with two side plates and a base plate arranged between the side plates, and that the operating lever and the emergency release lever are coupled to the base plate and essentially arranged between the side plates. The further emergency release lever is preferably also coupled to the base plate and is arranged essentially between the side plates. The side plates then offer suitable support points for Bowden cables or the like.

It is further preferred that the common pin is fixed rigidly to the base plate, in particular essentially centrally between the two side plates. In this way, an arrangement of the actuating lever and the emergency release lever that is as space-saving as possible is already possible, especially in relation to the side plates. The further emergency release lift can also be arranged in a space-saving manner in this way. In particular, it may be that the pulling device is guided through one of the two side plates. The pulling device is now correctly aligned for exerting the pulling force on the emergency release lever.

A further preferred embodiment of the locking arrangement according to the invention with a deflection rocker is characterized in that the further pulling device is guided through one of the two side plates. Analogously to the aforementioned traction device, this ensures a suitable alignment of the further traction device. In particular, it is preferred that the pulling device and the further pulling device are guided through respectively opposite side plates of the two side plates. With regard to the above release device, it is preferred that it is in any case indirectly attached to the base plate and is arranged essentially between the two side plates.

According to a preferred embodiment of the locking arrangement according to the invention with a deflection rocker, it is provided that a respective pivoting movement of the actuating lever and the emergency release lever essentially corresponds to a linear movement in one direction between the two side plates. Preferably also corresponds to a pivoting movement of the other emergency release lever in Essentially a linear movement in one direction between the two side plates.

A preferred embodiment of the locking arrangement according to the invention with a deflection rocker is characterized in that the traction device comprises a Bowden cable, that a core of the Bowden cable is attached to the emergency release lever and that a sheath of the Bowden cable is attached to a first side plate of the two side plates. With regard to the additional traction device, it is preferably provided that the additional traction device comprises an additional Bowden cable, that a core of the additional Bowden cable is attached to the additional emergency release lever and that a sleeve of the additional Bowden cable is attached to a second side plate of the two side plates.

A further preferred embodiment of the locking arrangement according to the invention with a deflection rocker is characterized in that the rocker arrangement has a push-pull actuating device for transmitting a push-pull force and that the actuating lever, preferably on its first actuating lever pivot arm, is used to actuate the push-pull actuating device this is coupled. Here and below, the transmission of a push-pull force means that the push-pull actuating device can be used to transfer both a tensile force—as with a Bowden cable—and a compressive force—in contrast to a Bowden cable. Such a push-pull actuation device can be used in particular to move the lateral rotary latches or swivel arms described above synchronously with the rotary latch articulated via the articulation device. The push-pull actuation device can in particular be a push-pull cable. Furthermore, it is preferred that a casing of the push-pull actuation device or the push-pull cable is attached to the first side plate. In this way, the advantages of the side plate already described above for the pulling devices are also realized for the push-pull actuation device.

According to a preferred embodiment of the locking arrangement according to the invention with a deflection rocker, it is provided that the deflection rocker has a further push-pull actuating device for transmitting a push-pull force and that the actuating lever, preferably on its second actuating lever swivel arm, for actuating the additional push-pull actuating device this is coupled. The further push-pull actuation device is preferably a push-pull cable or a further push-pull cable. In particular, it may be that a shell of the further push-pull actuator is attached to the second side plate.

A preferred embodiment of the locking arrangement according to the invention with a deflection rocker is characterized in that the rocker arrangement has a deactivation lever for locking the actuating lever, that the deactivation lever can be brought into a locking position and into a release position, that in the locking position the deactivation lever holds the actuating lever in the locking position and that in the release position of the decommissioning lever releases a movement of the actuating lever into the unlocked position. In other words, when the deactivation lever is in the release position, the actuating lever can move into the unlocked position without being significantly influenced by the deactivation lever. On the other hand, when the disabling lever is in the locked position, the operating lever is held in the locked position by the disabling lever.

The force required to hold the actuating lever in the locked position is preferably provided by a transmission device for moving the deactivation lever. This transmission device is preferably a push-pull actuator, which can in particular be a push-pull cable. A vehicle sliding door, which is the subject here, regularly has a deactivation switch, which z. B. with a square wrench or the like. must be actuated in order to deactivate the vehicle sliding door. Such a deactivation switch is then preferably connected to the deactivation lever by the transmission device or by the push-pull actuator. The force exerted by the push-pull actuator on the deactivation lever thus also holds the operating lever in the locked position. Since the rotary latch is regularly locked and unlocked according to the principle of a dead center, there is basically no pretension exerted by the rotary latch on the actuating lever in the direction of the unlocked position.

The decommissioning lever is preferably pivotably mounted on the common pin. It is preferred that the decommissioning lever is in the locked position engages the drive pin and holds the operating lever in the locked position.

The holding of the operating lever by the decommissioning lever can be both emergency unlockable and not emergency unlockable. In the emergency release variant, actuation of the emergency release lever engages the actuating lever and moves it to the unlocked position as usual, except that movement of the actuating lever must overcome the corresponding force exerted on the deactivation lever to hold the actuating lever. In the case of the non-emergency-lockable variant, on the other hand, actuation of the emergency release lever does not lead to a movement of the actuation lever, so that the rotary latch does not unlock either. This variant is preferably implemented in that the deflection rocker has a pawl for blocking the deactivation lever in the blocked position, which pawl comes into blocking engagement with the deactivation lever when the deactivation lever moves into the blocked position. The blocking engagement with the override lever prevents movement of the override lever from the locked position to the unlocked position. According to this variant, the decommissioning can only otherwise, z. B. done by pressing the already mentioned decommissioning switch, which then the pawl can be moved back from the blocking engagement with the decommissioning lever.

According to a preferred embodiment, the locking arrangement also includes a drive for selectively unlocking and locking the rotary latch. It is preferred that the drive has an electric motor and a drive lever coupled to the rotary latch for transmitting a movement of the electric motor to the rotary latch. It is particularly preferred here that the drive lever is outside of a force-effect chain of the actuating lever is. This means that when the rotary latch is locked or unlocked, the drive lever is moved by the drive, but this is done indirectly via the rotary latch.

Fig. 3a-f

the first embodiment of the deflection rocker according to the invention from 1 with five further exemplary embodiments of the deflection rocker according to the invention in a respective plan view.

In the 1 a first exemplary embodiment of the deflection rocker can be seen. The 2 shows this deflection rocker as part of a locking arrangement according to the invention of a vehicle sliding door 2, which is only partially shown here 1 The recognizable actuating lever 3 of the deflection rocker is used to move the rotary latch 1 of the locking arrangement and is coupled to the rotary latch 1 for this purpose via the linkage device 4, which is a rigid linkage lever. The rotary latch 1 consists here in a manner known from the prior art via a multi-part arrangement which is in a locked state - as in the 2 shown - and can be brought to an unlocked state, not shown here. In this respect, it is a rotary latch arrangement which consists of more than just one rotary latch in the narrower sense. In particular, the rotary latch 1 has a toggle lever arrangement with a dead center, which is not shown separately here on which toggle lever arrangement holds the rotary latch 1 in the locked state.

Due to the coupling via the articulation device 4, the locked state of the rotary latch 1 corresponds in particular to the 1 and 2 illustrated locking position of the operating lever 3. The unlocked state of the rotary latch 1 corresponds to the unlocked position of the operating lever 3 - not shown here 1 and 2 pivoted counterclockwise in the locked position.

The coupling exists both in the direction of the rotary latch 1 starting from the actuating lever 3 and in the direction of the actuating lever 3 starting from the rotary latch 1 . Specifically, the locking arrangement in the embodiment of 2 and, as is preferred, a drive for selectively unlocking and locking the rotary latch 1, which drive in turn has an electric motor 5 here. The corresponding movement of the rotary latch 1 by the drive leads to a movement of the actuating lever 3 into the locked position or into the unlocked position. The drive also has a gear in the form of a connecting rod 5a for transmitting a movement from the electric motor 5 to the rotary latch 1.

The deflection rocker 1 and 2 also has an emergency release lever 6a and another emergency release lever 6b. Actuation of the emergency release lever 6a or of the further emergency release lever 6b brings this into engagement with the actuation lever 3 via the driver pin 7 of the actuation lever 3 and moves the actuation lever 3 into the unlocked position. The actuating lever 3 and the emergency release lever 6a and the other emergency release lever 6b are mounted pivotably on the common pin 8 . Another driver pin 7a of the actuating lever 3 with the essentially identical function to the driver pin 7 is shown in FIGS Figures 3a, 3c and 3e to recognize.

Through the common pin 8 and through the corresponding bearing point on the common pin 8, both the operating lever 3 and the emergency release lever 6a and the other emergency release lever 6b in each Pivot arms 9a-d or actuating lever pivot arms 10a, b subdivided, these - at least those of a single emergency release lever 6a, b or actuating lever 3 - having essentially the same length.

The deflection rocker has a pulling device 11a and a further pulling device 11b, which pulling devices 11a, b are each a Bowden cable. The traction device 11a or its core is attached to the emergency release lever 6a or its first pivot arm 9a and the other traction device 11b or its core is attached to the other emergency release lever 6b or its first pivot arm 9c. How from the 2 shows, the tensile force exerted by the traction devices 11a, b on the emergency release levers 6a, b acts in opposite directions, but the direction of the torque exerted is identical, since the swivel arms 9a, c to which the respective traction devices 11a, b are attached are, based on the common pin 8 are also opposite.

At their respective other ends, the pulling device 11a and the further pulling device 11b are connected to a respective emergency release actuating device, not shown here, which is known per se from the prior art. The first emergency release actuation device connected to the traction device 11a serves as an example here for emergency release from the inside, so that this first emergency release actuation device is arranged so that it is accessible from the interior of the vehicle, which is not shown here. The second emergency release actuation device connected to the additional traction device 11b is used for emergency release from the outside, so that this second emergency release actuation device is arranged in such a way that it is accessible from outside the interior of the vehicle. This is also not shown in the figure.

Furthermore, the deflection rocker has a release device 12 which can be brought into an engaged state and into a release state. This is done here by energizing an electromagnet 12a of the release device 12, with this energizing bringing the release device 12 into the release state and leading to the actuation of a gripping arrangement 12b of the release device 12, so that actuation of the first emergency release lever 6a runs freely and accordingly does not lead to any movement of the actuating lever 3 .

How from the 1 As can be seen, the gripping arrangement 12b is disengaged from the driver pin 7 in the free-moving state of the free-moving device 12 and cannot take it with it when the emergency release lever 6a is actuated. The force effect chain from the traction device 11a to the emergency release lever 6a - and thus also to the actuating lever 3 - is then open. When the electromagnet 12 is not energized, the release device 12 is in the engaged state in which the gripping arrangement 12b is engaged with the driver pin 7 and consequently the driver pin 7 is carried along when the emergency release lever 6a is actuated. The force effect chain from the traction device 11a to the emergency release lever 6a and on to the actuating lever 3 is therefore closed when the release device 12 is in the engaged state. On the other hand, the release device 12 clearly has no influence on the functioning of the further emergency release lever 6b.

This release device 12 is primarily used to prevent an emergency unlocking and thus in particular an unlocking of the rotary latch 1 while the vehicle is traveling—and thus moving—with the vehicle sliding door 2 . Such an emergency release while driving is practically only possible from the inside, so that only the emergency release lever 6a that corresponds to the actuation of the emergency release from the inside has to be taken into account. If, for example, the electrical energy of the vehicle should fail, this would lead to the journey being aborted on the one hand and to a failure of the power supply to the release device 12 or its electromagnet 12a on the other hand, so that the release device 12 would automatically be brought into the engaged state, in which both emergency release levers 6a, b can bring about an unlocking of the rotary latch 1.

The common pin 8 is arranged on the base plate 15 of a rigid support assembly 13, which is shown in FIG 2 is shown. Specifically, the common spigot 8 is placed substantially centrally between two opposite side plates 14a,b of the carrier assembly 13. Both the traction device 11a and the further traction device 11b are guided through the side plates 14a, b, namely through respectively opposite side plates 14a, b. In this case, a sheath of the Bowden cable of the traction device 11a is on the first side plate 14a and a sheath of the Bowden cable of the traction device 11b is on the second side plate 14b attached. Recognizable corresponds to both the movement of the operating lever 3 between the locked position and the unlocked position as well as a respective movement of the emergency release lever 6a, b for engagement with the operating lever 3 essentially a linear movement in one in the 1 illustrated direction 16, which runs between the two side plates 14a, b.

As also from the 2 shows that the deflection rocker has a push-pull actuating device 17a - here a push-pull cable - which connects the actuating lever 3 to a first lateral rotary latch (not shown here) in such a way that this lateral rotary latch locks or unlocks the rotary latch 1. This lateral rotary latch is assigned to the vehicle sliding door 2 and is used to open and close it. The deflection rocker has a further push-pull actuating device 17b - also a push-pull cable - which connects the actuating lever 3 to a second lateral rotary latch in the same way, which second lateral rotary latch is arranged opposite the first lateral rotary latch in relation to the deflection rocker is. This second lateral catch is also assigned to the vehicle sliding door 2 and is used to open and close it. The push-pull actuators 17a,b are also attached to the first side panel 14a and second side panel 14b, respectively, by their respective sleeves.

The deflection rocker also has a decommissioning lever 18 which is pivotably mounted on the common pin 8 and which, as shown in FIG 1 is in its release position. In this release position, it does not affect movement of the operating lever 3 . The decommissioning lever 18 can also be pivoted - as shown in the 1 clockwise - can also be brought into its locked position, in which it holds the operating lever 3 in the locked position by engagement with the driver pin 7 . The override lever 18 can be actuated by either of two push-pull actuators 19a,b, also presently push-pull cables, which are also attached to the side plates 14a,b. The push-pull actuators 19a, b are connected to respective shutdown switches, not shown here.

The in the embodiment of 1 and 2 The mechanism implemented for decommissioning cannot be unlocked in an emergency. Specifically, the deflection rocker on a pawl 20, which for blocking the deactivation lever 18 by its bias in the clockwise direction - as shown in FIG 1 - is pivoted. The engagement with the deactivation lever 18 is such that the deactivation lever 18 cannot be moved back into its release position by actuating the emergency release lever 6a, b.

Finally, the deflection rocker has an emergency release button 21a for detecting an actuation of the emergency release lever 6a and a deactivation button 21b for detecting a locked position of the deactivation lever 18 .

The embodiment of 1 and 2 is also in the Fig. 3f shown. The respectively in the Figures 3a to 3e The exemplary embodiments of deflecting rockers according to the invention shown have only some of the functions just described compared to this first exemplary embodiment.

The embodiment of Figure 3a has in addition to the operating lever 3 only an emergency release lever 6a. A release or decommissioning is not planned.

The embodiment of Figure 3b has two emergency release levers 6a, b and the release device 12 of the first embodiment 1 and 2 on. The emergency release lever 6a essentially covers the other emergency release lever 6b in the illustration. A decommissioning is for the embodiment of Figure 3b not provided.

The embodiment of 3c has two emergency release levers 6a, b - which in turn covers the other emergency release lever 6b - and a decommissioning lever 18, so that the deflection rocker as for the embodiment of 1 and 2 described can be taken out of service. Since the deflection rocker of the 3c has no pawl 20, this decommissioning can be unlocked in an emergency by actuating the emergency release lever 6a, b. In contrast, the exemplary embodiment lacks 3c a release device.

The embodiment of 3d corresponds to that of 3c , Wherein here in the embodiment of 3c missing release device 12 is present.

The embodiment of Figure 3e finally corresponds to that of 3c , Where compared to the embodiment of 3c the pawl 20 as in the embodiment of 1 and 2 is present so that the decommissioning cannot be unlocked in an emergency. A release device, however, is missing.
