SUMMARY OF THE INVENTION

An object of the present invention is therefore to provide an emergency release with improved ease of use.

This task is solved by the subject matter of the independent claims. Further examples are given in the dependent claims. The aspects described below apply to the locking system with emergency opening function for a Vehicle door, for the frame module for a motor vehicle door, for the motor vehicle door module and also for the method for opening a vehicle door.

According to the invention, a locking system with an emergency opening function is provided for a vehicle door. The system has a lock device and an emergency opening device. The lock device has at least one door lock for releasably holding the vehicle door in the closed state of the vehicle door and an electric motor for opening the at least one door lock. The emergency opening device is provided for an emergency opening of the vehicle door as an additional opening device for opening the lock device and has an actuator arrangement with at least one actuator for generating opening force, which is in a mechanical operative connection with the lock device.

The emergency opening device is intended for emergency opening of the vehicle door as an additional opening device for opening the lock device.

This makes it possible to open the vehicle door even in an emergency, for example from the interior. When closed, the vehicle door is reliably held by the lock device. In addition, the vehicle door can be locked with the help of the lock device, which offers additional security and comfort.

According to the invention, the emergency opening device has a manually operable activation device with which the actuator arrangement can be activated for an emergency opening of the vehicle door.

According to the invention, the actuator arrangement for redundant emergency opening force generation has, as the primary actuator, an electric drive for generating a primary opening force, and as the secondary actuator, a manual drive for generating a secondary opening force, which are in mechanical operative connection with the lock device. If the primary actuator fails, the emergency opening of the door lock device is carried out by the secondary actuator.

The primary opening force can also be referred to as the primary emergency opening force; the secondary opening force can be referred to as secondary emergency opening force.

For example, the emergency opening of the door lock device is carried out by the manual drive, e.g. a lever or rotary handle for actuation (as the secondary actuator), if the electric drive (as the primary actuator) fails and the actual drive in the lock has also failed.

The primary actuator can also be called an emergency opening actuator,

The terms "primary" and "secondary" refer to the emergency opening function in addition to the opening function of the lock itself.

If the standard opening function of the lock, so to speak, is referred to as the primary opening function, since it is used every time it is opened, the additional actuator provided, e.g. the additional electric drive, would be intended for emergency opening as a secondary opening function and manual emergency opening as a tertiary opening function . There would then be three actuators on three levels: the first, i.e. primary actuator would then be the lock motor; the second, i.e. secondary actuator would then be the additional emergency opening motor; and the third, i.e. tertiary actuator would then be the manually operated emergency opening lever.

In one option, a second door lock is provided for releasably holding the same vehicle door when the vehicle door is closed. The second door lock has an electric motor for opening the second door lock. The emergency opening device is also provided as an additional opening device for opening the second door lock for emergency opening of the vehicle door.

If the primary actuator fails, the emergency opening of the door lock device is carried out by the secondary actuator.

According to the invention, the manually operable activation device can be moved from a starting position to a first position in order to activate the primary actuator in the first position to generate the primary opening force. The manually operable activation device can also be moved into a second position in order to generate the secondary opening force with the activation device.

DETAILED DESCRIPTION OF EMBODIMENTS

Before the figures are described in more detail, further aspects of emergency unlocking will be discussed below.

Emergency release levers can be connected to door locks for emergency release via Bowden cables, for example. In order to keep the force to be applied as low as possible, an emergency release supported by external force is provided. In one example, an emergency release lever (emergency release device) with three different (lift) levels is provided. These levels can be read by one or more microswitches. In order to trigger the emergency release, force must be applied to all locks using the lever and corresponding Bowden cables including Y-branches to be able to unlock at the same time. For this purpose, for example, an electric actuator is used to provide support, so that a small amount of manual strength is required, which can also be used by children, for example, in an emergency. Emergency unlocking is therefore particularly suitable for autonomous vehicles where a driver is not available to provide assistance in an emergency. If there is an emergency situation in which the doors need to be unlocked emergency, the passenger can activate the emergency unlocking device.

In one example, a first lifting stage of an operating lever is provided: If the first lifting stage is recognized via the corresponding (micro) switch, an electronic signal is transmitted to the locks. If the on-board electrical system is still active, the locks are unlocked using electric drives integrated into the door locks, e.g. OBW motors (open-by-wire motors); The door pops open due to the seal counter pressure and can be opened manually. The doors are opened via emergency unlocking by wire.

In one example, a second lifting stage of the operating lever is also provided: If the second lifting stage is detected via the corresponding microswitch, a check is first made to see whether an OBW opening of the locks is possible. If this is not the case (for example due to the failure of a door lock, damage to the cable supply, defect in the electronics, etc.), a device is activated which forces the emergency release Bowden cables of all locks to be operated, e.g. an additional closing aid (repurposed for emergency release) which applies sufficient force to activate the Bowden cable for emergency release of all locks, provided the vehicle electrical system voltage is still present. This can be located close to the actual operating lever and both (lever and device) can be connected to the emergency release Bowden cables of the locks via a Y-switch on the Bowden cable. As an extension of this lifting stage, a separate energy storage unit can also be integrated, which in such an emergency situation (failure of the on-board power supply) reserves enough energy to activate the closing aid for emergency unlocking. The doors are therefore opened via emergency unlocking by an electric actuator.

The first two lifting stages can be made haptically recognizable to the user by means of a corresponding notch on the lever.

In another example, a third stroke stage of the actuating lever is also provided: If there is a total system failure and there is no back-up energy storage to activate the primary actuator, there is the possibility of pulling the emergency release lever (with a corresponding longer stroke distance). than the previous two lifting stages) to unlock the locks, i.e. emergency unlocking or emergency opening. The doors are opened via emergency unlocking using manual force.

In one example, three stroke stages of the operating lever are provided for emergency opening: In the first stage, the opening is carried out by the lock motor(s). In the second stage, the opening is carried out by the additional primary actuator(s). In the third stage, manual opening takes place using the operating lever. For example, two microswitches are then provided, one for the first stage and one for the second stage.

In another example, two lifting stages of the operating lever are provided: In the first stage, the opening is first activated by the lock motor(s). If this does not work, the opening is activated by the additional primary actuators. In the second stage, manual opening takes place using the operating lever. For example, only one microswitch is then provided, one for the first stage.

In one example, a microswitch is provided which detects a manual actuation, i.e. movement of the operating lever and activates an opening by the OBW motor in the lock. If this does not work, the additional drive is activated, i.e. the primary actuator that implements the powered emergency opening. If this does not work either, a mechanical, i.e. manually driven, emergency opening occurs in a subsequent stroke of the operating lever.

In one example, the microswitch is arranged in the operating lever in order to directly detect the movement of the operating lever.

In another example, the microswitch is not arranged on the operating lever, but on a power transmission means that is connected to the operating lever in order to detect the movement of the operating lever on the power transmission means.

For example, the two stages, a) opening by the lock motor and b) opening by the primary actuator, are triggered together in the first stage. For example, the internal lock motor, e.g. the OBW drive, requires approx. 40-50 ms and the electric motor intended as the primary actuator requires approx. 700-1000 ms. For example, the two drives can also be triggered at the same time. Either the actuator then pulls on the already opened lock, or it opens the lock.

Instead of an emergency release lever, a combination of a button for the by-wire emergency release and a corresponding lever for the back-up emergency release by manual force can also be provided.

In addition, a possibility can be provided for a control center to initiate an emergency unlocking from externally, e.g. by appropriately opening the OBW or actuating the actuator.

One option provides for the emergency release functionality to be integrated into the system's existing closing aids. To do this, they require two directions of rotation instead of just one, which means that a corresponding Bowden cable can be operated. Using this variant, an additional component (the motor for emergency unlocking) can be saved.

The one presented for the required technical understanding Fig. 1 shows schematically an example of a locking system 10 with an emergency opening function for a vehicle door. The locking system 10 has a lock device 12 and an emergency opening device 14. The lock device 12 has at least one door lock 16 for releasably holding the vehicle door in the closed state of the vehicle door and an electric motor 18 for opening the at least one door lock. The emergency opening device 14 is intended for emergency opening of the vehicle door as an additional opening device for opening the lock device. The emergency opening device 14 has an actuator arrangement for generating opening force 20 with at least one actuator 22. The actuator arrangement 20 is in a mechanical operative connection with the lock device.

A first connecting line 24 schematically indicates the actuation of the door lock by the electric motor 18. The mechanical operative connection of the actuator 22 with the lock device 12, for example with the door lock 16, is represented by a second connecting line 26.

A dashed frame 28 indicates the vehicle door.

The door lock 16 is designed to releasably hold the vehicle door in, for example, a main catch and a preliminary catch. In addition, the door lock can also assume an open position in which the vehicle door is not held by the door lock 16.

For example, sliding doors, swing doors or swing-sliding doors can be kept in the closed state with the lock device. Additional application of compressed air during vehicle operation is then no longer necessary.

The emergency opening device can also be referred to as an emergency opening device or emergency opening arrangement. The lock device can also be referred to as a lock device or lock arrangement. The actuator arrangement can also be referred to as an actuator device or actuator device.

The door lock is designed, for example, with a rotary latch and a pawl. The rotary latch and the pawl form the locking mechanism of the door lock. The emergency release, for example, intervenes in the barrier to open the lock.

The at least one door lock is designed with a motor drive integrated into the door lock, for example an electric motor, with which the door lock is actuated during normal operation of the vehicle.

In one variant, the actuator arrangement has an electric actuator. In another variant, the actuator arrangement has at least one manually operated actuator.

The term “actuator” refers to the generation of the actuating force to be transmitted. This can be done via an electric drive or using manually applied force.

The primary actuator is, for example, an electric motor and the secondary actuator is, for example, a manually movable lever or rotary handle.

In one example it is provided that the lock device is designed with an electrical closing aid. The closing aid is used, for example, to pull the door against the door seal into the closed position of the door.

In one example it is provided that the lock device is designed with an electrical opening aid. For example, a so-called pushout unit is provided.

The vehicle door can have one door element or two door elements.

This is also presented for the necessary technical understanding Fig. 2 shows another example of the locking system 10 with emergency opening function. The emergency opening device 14 has a manually operable activation device 30, with which the actuator arrangement 20 can be activated for an emergency opening of the vehicle door. A third connecting line 32 indicates the activation of the actuator arrangement 20.

Manual operation provides additional security if, for example, the supply of electrical energy on board a vehicle has failed and no power is available.

The manually operable activation device 30 is designed, for example, as an emergency lever, emergency switch or emergency knob. In one example, the manually operable activation device 30 is a lever. In another example, the manually operable activation device 30 is a carriage. In another example, the manually operable activation device 30 is a rotary switch. A freewheel can be formed on the lever, the carriage or the rotary switch.

Fig. 3 shows a variant of the locking system 10 according to the invention with an emergency opening function. For redundant emergency opening force generation, the actuator arrangement 20 has an electric drive 34 as a primary actuator for generating a primary opening force and a manual drive 36 as a secondary actuator for generating a secondary opening force, which are in mechanical operative connection with the lock device 12. If the primary actuator fails, the emergency opening of the door lock device is carried out by the secondary actuator.

A fourth connecting line 38 represents the (mechanical) operative connection of the electric drive 34; a fifth connecting line 40 represents the (mechanical) operative connection of the manual drive 36. A sixth connecting line 42 represents the activation of the electric drive 34 by the manually operable activation device 30; a seventh connecting line 44 represents the activation of the manual drive 36 by the manually operable activation device 30.

The redundant emergency opening force generation results in a total of two, i.e. double redundancy for the door lock: If opening via the normal motor in the door lock no longer works, the electric drive for the emergency opening is used as the first redundancy. If this doesn't work either, the manual drive for the emergency opening is used as a second redundancy.

This results in multi-level security with simultaneous user and operating comfort. If it is no longer possible to open the door lock using the lock motors, for example if the lock motors are defective or have failed, in an emergency situation you can first try to open the doors with the electric actuator, i.e. the electric drive. If it is no longer possible to open the door lock using the electric actuator, for example if there is a complete breakdown of the on-board electrical system or a defect or failure of the electric actuator, the door can be opened in an emergency situation with the manual actuator, i.e. the manual drive to open.

According to the invention, the emergency opening device for redundant opening force generation has the primary actuator and the secondary actuator. The primary actuator and the secondary actuator are each in mechanical operative connection with the door lock. The primary actuator and the secondary actuator form the actuator arrangement 20, which is in mechanical operative connection with the lock device.

According to the invention, the electric drive 34 is in a primary mechanical operative connection with the door lock. According to the invention, the manual drive 36 is in a secondary mechanical operative connection with the door lock.

In one option it is provided that the primary mechanical active connection and the secondary mechanical active connection are integrated, i.e. take place together.

In one option it is provided that the primary mechanical active connection and the secondary mechanical active connection take place separately.

For example, the primary actuator is a separate motor. In one variant, the primary actuator is a motor intended for another application in the area of the vehicle door, which is used as an additional application for emergency opening. For example, the motor of a closing aid operates in a first direction in order to apply a closing force to the vehicle door. The motor of the closing aid operates in a second direction, for example opposite to the first, in order to open the door lock in an emergency.

In one option it is provided that the electric drive 34 is a motor that can otherwise also be used for other purposes in vehicle doors. For example, electric closing aids are suitable as electric drives for emergency opening, since closing aids are, on the one hand, compact and can be manufactured economically and, on the other hand, are also powerful enough to ensure reliable emergency opening of the vehicle door.

The electric drive 34 forms an auxiliary actuator for the vehicle lock.

In a variant of the example not shown in detail Fig. 3 a second door lock is provided for releasably holding the same vehicle door in the closed state of the vehicle door. The second door lock has an electric motor for opening the second door lock. The emergency opening device 14 for emergency opening of the vehicle door is also provided as an additional opening device for opening the second door lock.

In one example, two movable door elements, i.e. door leaves or door wings, i.e. two vehicle doors arranged as a pair, are provided. Each door or each door leaf is equipped with two door locks. Three, four or five door locks can also be provided per door leaf.

The one presented for the required technical understanding Fig. 4 shows another variant of the locking system 10 with an emergency opening function. The lock device 12 has at least a first door lock 46 and a second door lock 48 for releasably holding the same vehicle door in the closed state of the vehicle door and an electric motor M for opening the first and second door locks 46, 48. The actuator arrangement 20 is in mechanical operative connection with the first door lock 46 and the second door lock 48.

For example, the first door lock 46 has a first electric motor 50 for opening the first door lock 46, and the second door lock 48 has a second electric motor 52 for opening the second door lock 48.

In another example, a common motor is provided for the first door lock 46 and the second door lock 48 for opening the first and second door locks 46, 48.

The mechanical operative connection of the actuator arrangement 20 with the first door lock 46 shows an eighth connecting line 54; the mechanical operative connection of the actuator arrangement 20 with the second door lock 48 shows a ninth connection line 56.

In one example, the emergency actuation is done manually. In another example, the emergency actuation is done electrically. In a further example, the emergency actuation is carried out either manually and/or electrically.

In one example, the emergency opening device 14 is provided for opening the first door lock 46 and the second door lock 48 and has an actuator for generating the opening force, which is in mechanical operative connection with the first door lock and the second door lock.

The emergency opening device can also be referred to as an emergency opening device.

In one example, the first and second door locks 46, 48 are intended for locking and unlocking the same vehicle door.

The first door lock and the second door lock can be opened with the emergency opening device as an additional opening device, i.e. the first and second door locks can be opened with the emergency opening device.

The first and second door locks 46, 48 can be controlled electrically in normal operation, that is, they are controlled electrically in normal operation.

In one example, two movable door elements, i.e. door leaves or door wings, i.e. two vehicle doors arranged as a pair, are provided. Each door is equipped with two door locks. With two door leaves, four door locks are provided, all of which are mechanically connected to the actuator arrangement of the emergency opening device.

For example, the doors are movably hinged on the right and left and are held together in the middle and on the upper and lower frame areas.

In one variant it is provided that two doors are formed, each of which has two door locks, i.e. a total of four door locks. Each of the door locks has a motor in the lock. A closing aid is also provided on at least one door lock. For example, all four door locks are equipped with a closing aid. One or more of the closing aids can be provided as a secondary function as the primary actuators of the actuator arrangement. For example, two closing aids are provided, e.g. one for each door, and one closing aid takes on the additional function. The mechanical connection to the four door locks can then be made via Bowden cables and/or linkages, which can, for example, be easily installed in the door frame or along the door frame areas.

In a variant of the example not shown in detail Fig. 4 The actuator arrangement for redundant opening force generation has, as the primary actuator, an electric drive for generating a primary opening force and, as the secondary actuator, a manual drive for generating a secondary opening force. The primary actuator and the secondary actuator are in mechanical operative connection with the first door lock and the second door lock. If the primary actuator fails, the emergency opening of the door lock device is carried out by the secondary actuator.

Fig. 5 shows a variant of the locking system 10 with an emergency opening function with an electric actuator, for example the electric drive 34, and a manually operable actuator, for example the manual drive 36, and two door locks, for example the first door lock 46 and the second door lock 48, which have the two Actuators can be opened emergency if the actuation takes place via the manually operable activation device 30.

It (see also Fig. 6 ) it is provided that the manually operable activation device 30 can be moved from a starting position P ₀ to a first position P ₁ in order to activate the primary actuator in the first position to generate the primary opening force. The manually operable activation device 30 can also be moved into a second position P ₂ in order to generate the secondary opening force with the activation device 30. The second position P ₂ can also be referred to as the end position.

The electric drive 34 is a drive provided in addition to the lock motor M. For example, the electric drive 34 is stronger than the lock motor.

In one example (see Fig. 6 ) it is provided that the manually operable activation device has a sensor 58 which is designed to detect a movement of the activation device from the starting position P ₀ to the first position P ₁ or (as an option) the second position P ₂ and to generate an activation signal for the to provide primary actuator.

As an option, it is provided that the primary actuator can be activated with the manually operable activation device 30 in such a way that the emergency opening has already been carried out when the manually operable activation device 30 moves from the first position P ₁ to the second position P ₂ .

The sensor 58 is, for example, a microswitch or microbutton that is arranged in the activation device 30. For example, a control for the primary actuator is provided which has a relay (not shown) which activates the primary actuator when an activation signal is present.

In one option, the manually operable activation device 30 forms the secondary actuator provided as the manual drive 36.

Fig. 6 shows an example of the locking system 10 in the context of a two-leaf vehicle door 60 with a first door leaf 62 and a second door leaf 64. In Fig. 6 the mechanical active connections of the locking system 10 are shown schematically.

The first door leaf 62 and the second door leaf 64 are, for example, held movably as sliding pivoting leaves with a fitting (not shown in detail) on opposite side edge regions. In order to keep the first door leaf 62 and the second door leaf 64 in the closed state, i.e. to temporarily fix them, a locking device 65 is provided in the middle area at the top, into which the door leaves engage with a matching locking counterpart when the door leaves are closed.

In order to hold the first door leaf 62 laterally in the closed state, two door locks, i.e. a first door lock 66a and a second door lock 66b, are provided on the (left) lateral edge of the first door leaf,

In order to hold the second door leaf 64 laterally in the closed state, two door locks, i.e. a third door lock 68a and a fourth door lock 68b, are provided on the (right) lateral edge of the first door leaf.

The door locks 66a, 66b, 68a, 68b each have an electric motor for actuating the respective door lock.

The manually operable activation device 30 is provided for the emergency opening function of the locking system 10. As an option, a coupling device 70 is provided, to which the manually operable activation device 30 is connected. The coupling device 70 is designed, for example, as a pivotable adapter lever 72, which is held at one end via a fixed bearing 74. The manually operable activation device 30 is connected to the pivotable adapter lever 72, for example with a first Bowden cable 76 or another mechanical connecting element. The primary actuator, i.e. the electric drive 34, is connected to the pivotable adapter lever 72 with a second Bowden cable 78 or another mechanical connecting element.

The manually operable activation device 30 is designed, for example, as the secondary actuator, ie the manual drive 36 and is connected via the first Bowden cable 76. The primary and secondary actuators are connected via the coupling device 70 to a common actuator 80, which is coupled to the lock device 12.

In one option of the common adjusting device 80, Bowden cables are provided for power transmission. In one option of the common adjusting device 80, push rods are provided for power transmission. For example, a combination of Bowden cables and push rods is provided.

The common actuating device 80 is used to transfer the generated emergency opening actuating forces to the door locks to open the door locks. This is done, for example, by pivoting the adapter lever 72 by the actuators, which then leads to movements on the Bowden cables connected to it.

For the mechanical connection of the adapter lever 72 to the door locks of the first door leaf 62, a third Bowden cable 82 is provided, which connects the adapter lever 72 to a first Y-switch 84. A fourth Bowden cable 86 and a fifth Bowden cable 88 connect to the first Y-switch 84, which connect the first Y-switch 84 to the first door lock 66a and the second door lock 66b, respectively.

The third Bowden cable 82 can also be referred to as the first control element; the fourth Bowden cable 86 can be referred to as a second control element, and the fifth Bowden cable 88 can be referred to as a third control element. The fourth and fifth Bowden cables 86, 88 therefore form two further actuating elements connected to the first Y-switch 84, which are each connected to one of the two door locks 66a, 66b of the first door leaf 62.

Analogously, the sixth Bowden cable 92 forms another first control element; the seventh Bowden cable 96 forms a further second control element and the eighth Bowden cable 98 forms a further third control element. The seventh and eighth Bowden cables 96, 98 therefore form two further actuating elements connected to the second Y-switch 94, which are each connected to one of the two door locks 68a, 68b of the second door leaf 64.

In a further example, not shown in detail, it is provided that the common adjusting device 80 has a first adjusting element which is connected to the coupling device 70 and is connected to one of the two door locks, and a second adjusting element which connects the first adjusting element to the other of the two door locks .

The term “connect” refers to the transferability of a positioning force, for example tensile and/or compressive forces.

In another example, the common actuator is connected to one of the two door locks and a connecting element connects one of the two door locks to the other of the two door locks.

For the mechanical connection of the adapter lever 72 to the door locks of the second door leaf 64, a sixth Bowden cable 92 is provided, which connects the adapter lever 72 to a second Y-switch 94. A seventh Bowden cable 96 and an eighth Bowden cable 98 connect to the second Y-switch 94, which connect the second Y-switch 94 to the third door lock 66a and the second door lock 66b, respectively.

In one variant it is provided that the first door lock 66a and the second door lock 66b are mechanically connected to one another, for example coupled. As an option, for example, it is provided that a tension element is arranged to transmit actuating forces for emergency opening. As a further option, for example, it is provided that push rods are provided between the first door lock 66a and the second door lock 66b of the first door leaf 62, or between the first door lock 68a and the second door lock 68b of the second door leaf 64, for mechanical coupling for emergency opening.

In Fig. 6 is also indicated by dashed lines that, for example, instead of the fifth Bowden cable 88, or in addition, a first push rod 90 can be provided between the first door lock 66a and the second door lock 66b. In Fig. 6 is also indicated by dashed lines that, for example, instead of the eighth Bowden cable 98, or in addition, a second push rod 100 can be provided between the third door lock 66a and the fourth door lock 66b.

In an in Fig. 6 In the option shown, the manually operable activation device 30 designed as the manual drive 36 and the primary actuator, ie the electric drive 34, are connected in parallel to the coupling device 70. For example, a freewheel is provided on the coupling device 70, so that when actuated by the primary actuator, ie the electric motor, the secondary actuator, ie the manually operable activation device, can remain in the first position P ₁ .

Fig. 7 shows a variant of the connection of an electric actuator and a control element provided as a manual actuator. In the in Fig. 7 In the option shown, the primary actuator, ie the electric drive 34, is arranged in series and connected to the coupling device 70 via the manually operable activation device 30 designed as the manual drive 36. For example, a freewheel is provided on the secondary actuator, ie on the manually operable activation device, so that the primary actuator, ie the electric motor, does not have to be moved when actuated by the manually operable activation device.

In one variant, the manually operable activation device is arranged in series and connected to the coupling device via the primary actuator.

In a first example, the primary actuator and the manually operable activation device 30 are arranged in parallel and both are connected to the coupling device. In a second example, the primary actuator and the manually operable activation device are arranged in series.

In Fig. 5 As an option, it is indicated by dashed lines that a backup energy supply 102 can be provided for the electric drive 34. This option can also be provided for the other variants, ie for the examples shown in the figures and the variations mentioned in the description, in particular for the execution according to Fig. 2 , Fig. 3 , Fig. 4 , Fig. 7 , Fig. 8 and Fig. 11 .

In one option, the first actuator, ie the electric drive 34, is designed with a correspondingly responsive and fast-working electric motor, for example with a gearbox, so that when the first actuator is functioning it is ensured that the user who uses the manually operable activation device 30 pulls until it stops in the second position P ₂ , no force has to be applied to open the door lock, since the electric drive 34 in the form of the first actuator has already carried out the emergency opening of the door lock. The first actuator, which is actuated, for example, via a button or other sensor, is therefore faster than manual actuation. This function of the manually operable activation device can also be referred to as an electrical overtaking function.

In one example, the manually operable activation device 30 includes a lever. The lever is designed with an idle stroke, so that moving the lever first generates the signal for the electric drive of the emergency opening, so to speak as a first attempt. The manual drive is then activated shortly afterwards, i.e. a little later, as a second attempt, so to speak.

In a further example, a freewheel is provided on the coupling device 70. For example, the first actuator and the second actuator are attached to a common coupling element of the coupling device in order to act on the common actuator 80 via the coupling element. The coupling element is, for example, the adapter lever 72. For example, the attachment is carried out using suspended cables, for example with Bowden cables.

If the actuation is carried out using the first actuator, the Bowden cable of the second actuator can remain due to the freewheeling. If the second actuator is then actuated, the second actuator pulls into the void at least over the distance of the freewheel.

If the first actuator fails, the second actuator can pull on the coupling element, while the Bowden cable of the first actuator can remain due to the freewheel. If the first actuator is then actuated, the first actuator pulls into the void at least over the distance of the freewheel.

The actuator arrangement with the coupling device 70 and the common actuating device 80 can also be referred to as an emergency mechanism.

The common adjusting device 80 is connected to the at least one door lock. In the case of two door locks, in one example the common adjusting device is connected to the first door lock and the second door lock.

In one example, the coupling device 70 is designed as the adapter lever 72, which is coupled to the lock device 12 on the output side and to the actuator arrangement 20 on the drive side.

The coupling device 70 is designed, for example, as a control box or switch box.

The lock device 12 has, for example, a first door lock 210 and a second door lock 212 for a first door leaf. The lock device 12, for example, also has a further first door lock 214 and a further second door lock 216 for a second door leaf.

As an option, it is provided that the at least one door lock of the lock device 12 is attached to the frame structure 202. As a further option it is provided that at least one actuator of the actuator arrangement is attached to the frame structure. In one example, the manually operable activation device 30 is also attached to the frame structure and, when installed, is accessible from an interior of a vehicle.

As a further option, it can be provided that the at least one door lock of the lock device 12 is attached to the vehicle door 202.

The frame segments are preferably load-bearing profiles that can also be used, for example, to dissipate crash loads. The profiles can be connected by welding, screwing or riveting.

In Fig. 8 a fitting system 218 for movable attachment of at least one vehicle door element to a vehicle is indicated. The fitting system 218 has, for example, a sliding-pivoting mechanism for a vehicle door designed as a sliding-pivoting door.

In Fig. 8 is shown as an option of the frame module 200 that at least one vehicle door element is provided, which is movably attached to the frame structure with the fitting system 218. For example, two vehicle door elements 220, 222 are provided, which are designed as a two-leaf vehicle door and with which a common opening can be closed.

In one option it is provided that the frame module has 200 vehicle door elements.

As an option, it is provided that the two vehicle door elements 220, 222 rest against each other in a central area in the closed position.

As a further option (not shown in further detail), it is provided that the at least one vehicle door element has a circumferential door seal 224.

In one option it is provided that the frame module 200 has no vehicle door elements.

In Fig. 8 the operative connection from the first door lock 210 to the second lock 212 of the right door leaf is indicated by a first connecting line 226. Instead, a direct mechanical active connection from the actuator or the coupling device or the Y-switch can also be provided. A second connection line 228 represents the connection to the door locks of the other door wing and, for example, connects the first door lock 210 of the right door wing to the first door lock 214 of the left door wing. Instead, a direct mechanical active connection from the actuator or the coupling device or the Y-switch can also be provided. The mechanical operative connection of the first door lock 214 of the left door leaf with the second door lock 216 of the left door leaf is indicated by a third connecting line 230. Instead, a direct mechanical active connection from the actuator or the coupling device or the Y-switch can also be provided.

Fig. 9 shows another example of the in Fig. 8 Section marked with a dashed circle. The door lock 210 is attached to the frame segment 204c. A first Bowden cable 232 connects the door lock 210 to the actuator arrangement 20 (not shown in detail). The first Bowden cable 232 is suspended, for example, on an adjusting lever 234 of the door lock 210. A second Bowden cable 236, which is also attached to the adjusting lever 234 of the door lock 210, connects the door lock 210 to the door lock of the other door leaf. To connect the door lock 210 to the other door lock of the same door leaf, a connecting rod 238 is provided, which is also connected to the adjusting lever 234 of the door lock 210 via an articulated connection 240.

The frame module 200, for example, has all components. This simplifies the assembly of the vehicle doors. If the components are pre-assembled on the frame module, there are further advantages in the assembly processes. The frame then only needs to be attached to a vehicle structure and connected to the vehicle's own electrical system.

The frame module is therefore particularly suitable for passenger transport vehicles, for example so-called people movers, which are intended as a type of minibus for use in urban areas and where it must be ensured that people in the vehicle can get out in an emergency. The two-stage emergency opening offers the possibility of opening even for people with relatively little strength, such as children.

The formation of a surrounding frame also improves noise reduction, for example. Producing it as a frame module also allows smaller assembly tolerances, which has an advantageous effect on the visual impression of the gap dimensions, and last but not least for safety, as more precise force control is possible with smaller gap dimensions.

According to one aspect, an assembly method is also provided in which a frame module is prefabricated with all or at least the essential components is placed and mounted on a floor platform of a vehicle, and adjacent surfaces are attached to the frame module.

Fig. 10 For better illustration, shows an example of a vehicle 250 in the form of a people mover with a vehicle door 252 which has the locking system 10 with an emergency opening function.

Fig. 11 shows an example of a pre-assembled door module for a motor vehicle door with emergency opening function with frame and inserted door elements. Fig. 11 provides a motor vehicle door module 300 that has at least one vehicle door element 302 and a locking system 10 according to one of the preceding examples. The at least one vehicle door element 302 can be releasably locked on a vehicle with the lock device in a closed state of the vehicle door. In Fig. 11 Two door leaves 302a and 302b are shown as an example. An at least partially circumferential frame 304, for example as a U-shaped frame, serves to attach to a vehicle structure and at the same time to attach the components of the door module. The door leaves 302a and 302b are movably held on the frame 304 via fittings 306. The mechanical operative connections of the emergency opening device 14 to the door locks 310 of the lock device 12 are indicated by dashed lines 308.

The term vehicle door element refers to the movable (main) component of a vehicle door, i.e. the door leaf. The vehicle door element can also be referred to as a vehicle door.

In one example of the motor vehicle door module, a fitting system is provided for movably attaching the at least one vehicle door element to a vehicle. The fitting system has, for example, a sliding-pivoting mechanism and the at least one vehicle door element is designed as a sliding-pivoting door.
