Description

The present invention relates to an emergency operating device for a vehicle, in particular a rail vehicle, with an operating element for a control device and a shield assigned to the operating element, the control device unlocking an access device, in particular a door, to the vehicle from a rest position when the operating element is actuated Shield in a closed state located in its rest position actuator shields against unhindered access. It also relates to a vehicle with such an emergency operating device.

A large number of specifications and standards exist for public transport, in particular rail transport, which define the necessary properties of the vehicles used. Specifications regarding the safety of the transported passengers often play a central role here. Typically, there are specifications to the effect that precautions must be taken in the vehicle that allow the passengers to leave the vehicle quickly and safely in an emergency. For example, part of the "Technical Specification for Interoperability" (TSI) issued by the European Commission, namely the so-called TSI-RST, stipulates in a variant that an emergency opener (internal emergency operation) for vehicle doors used by passengers is independent of the speed signalling and must be able to be triggered by at least two consecutive operations (see TSI-RST, Chapter 4.2.2.4.2.1 g).

In some known vehicles, for example the vehicles of the ICE 1 series of Deutsche Bahn AG, the problem was solved by means of an emergency actuation device in which an actuation element in the form of an emergency handle (for manual door unlocking) is used in combination with an emergency switch. In normal operation, the emergency handle is mechanically decoupled from a shaft that triggers door unlocking. In an emergency, the emergency handle is only coupled to the shaft via an electromagnet when the emergency switch is actuated (first actuation in the sense of the TSI) (the emergency handle is therefore "activated"). Only then is the door unlocked when the emergency handle is actuated (second actuation in the sense of the TSI). Frequently, a pane covering the emergency switch first has to be smashed in order to be able to actuate it (see ICE 1), so that three consecutive actuations as defined by the TSI are required.

This solution does have the advantage that it could also be used (at least in one variant without the pane covering the emergency switch) for regular local door unlocking, such as is necessary for maintenance and cleaning of the vehicle by appropriate personnel. However, it has the disadvantage that it is comparatively complicated and expensive due to the required supply of (a not inconsiderable) power to the electromagnet (which must also be guaranteed in emergency situations).

In other known vehicles, for example the vehicles of the "Sprinter Lighttrain" series of the Dutch railway company, the problem was solved by means of a generic emergency actuation device in which the emergency handle is located behind a shield in the form of a disk. This pane is bolted to the vehicle via a frame and must first be knocked in (first actuation as defined by the TSI) in order to then release the doors by actuating the emergency handle (second actuation as defined by the TSI).

This solution does have the advantage of being simpler and more robust. However, the absolutely necessary destruction of the pane harbors a certain risk of injury (which could be eliminated with tools such as an emergency hammer, but this in turn means additional effort), on the other hand, the mandatory destruction of the pane requires a comparatively complex replacement of the latter after it has been destroyed .

An emergency operating device not limited to vehicles, in particular rail vehicles, corresponding to the other features of the preamble of claim 1 or 13 is known from US-A-4,164,095A .

The present invention is therefore based on the object of providing an emergency operating device or a rail vehicle of the type mentioned at the outset which does not have the abovementioned disadvantages or at least has them to a lesser extent and, in particular with a simple design, is a compact and reliable device for local unlocking of access points to the vehicle.

The present invention solves this problem based on an emergency operating device according to the preamble of claim 1 by the features specified in the characterizing part of claim 1. It also solves this problem based on an emergency operating device according to the preamble of independent claim 13 by the features specified in the characterizing part of claim 13 .

The present invention is based on the technical teaching that, with a simple design, a compact and reliable device for local unlocking of the access points to the vehicle (for example doors or possibly also windows) is made possible if the shielding includes a locking device that is simply in a short, one-off unlocking action, for example in a single movement, with or without tools (such as keys or the like) can be unlocked so that the shield can be opened, after which the actuating element for actuating the emergency unlocking of the access device (ie the door etc.) is actuated can be.

Compared to the known designs with an emergency switch (to "activate" the actuator), this design has the advantage that it is pure can be designed mechanically, which greatly simplifies their manufacture and maintenance.

Compared to the known designs with the firmly screwed glass pane to be destroyed, the design according to claim 13 has the advantage that on the one hand it reduces the risk of injury because the glass pane can be dispensed with. In the case of shielding with such a glass pane, the emergency release can also be actuated (possibly reversible) (for example by cleaning staff or the like) without the glass pane having to be destroyed.

According to one aspect, the present invention therefore relates to an emergency actuation device for a vehicle, in particular a rail vehicle, with an actuation element for a control device and a shielding associated with the actuation element, with the control device opening an access device, in particular a door, to the vehicle as a result of actuation of the actuation element from a Rest position unlocked. In a closed state, the shield shields the actuating element, which is in its rest position, from unhindered access. The shielding comprises a locking device which can be brought into an unlocked state by means of a brief, one-time unlocking action, in particular a single movement of the hand, the shielding being able to be brought into an open state when the locking device is in the unlocked state. The shield is removed from the actuator in the open condition, thereby enabling operation of the actuator.

In principle, the shield can be designed in any suitable way, as long as it can be moved in the unlocked state of the locking device in such a way that the actuating element is free for actuation. For example, it can be provided that the shielding is only held in a corresponding holder (for example in one or more retaining rails) and can be completely removed (e.g. withdrawn or lifted) from the emergency actuation device when the locking device is in the unlocked state. In preferred variants of the emergency actuation device according to the invention, however, the shielding is permanently attached to the emergency actuation device, so that it cannot be lost even when the locking device is in the unlocked state.

Provision is preferably made for the shielding to be held by a holding element. The shielding is preferably articulated in a pivotable manner on the holding element via at least one pivot joint, since this achieves a design that is particularly easy to operate. Additionally or alternatively, the retaining element can be attached to a housing of the emergency actuation device via at least one connecting means. In this case, it can then also be detachably fastened in order to enable it to be easily exchanged.

In principle, the locking device can be designed in any suitable way in order to realize the desired simple and quick unlocking (eg with one hand movement). In preferred variants of the emergency actuation device according to the invention, the locking device comprises at least one locking element that can be easily destroyed during the unlocking operation and shears off, tears off or tears with a single action (by applying a correspondingly high force and/or a jerky actuation). In particular, it can be a seal (for example a conventional wire seal).

The force for destroying the locking element can also be applied directly via the actuation or opening of the shield (that is, bringing it into its open state), so that no separate actuation is required for unlocking and opening the shield. A particularly rapid opening of the shielding is hereby possible in an advantageous manner.

This design also makes it possible to attach the locking element in such a way that it can be destroyed (for example thanks to appropriate lever ratios) by anyone (possibly also weaker persons) with a reasonable expenditure of force. On the other hand, the level of force required for destruction can be adjusted in such a way that unintentional destruction is generally avoided.

In the invention according to claim 13, it is provided that the locking device comprises at least one magnetic element, which holds the shielding in the closed state without any further external force being applied. In this case, the magnetic element can also form at least part of the shield itself.

With this design, on the one hand, a disturbing noise development caused by a loose cover can be reliably prevented. On the other hand, the force exerted by the magnetic element can be set so large that it completely locks the cover. The advantage of this design is that it allows the shield to be opened and closed without any additional tools (whereby the level of operating force required prevents inadvertent opening). The magnetic device also has the advantage that the force acting against the opening of the shield decreases as the shield opens, so that it does not impede the subsequent actuation of the actuating element. In particular, the magnetic element can then also be used in a simple manner to lock the shielding in its open position.

If it is desired that the shielding cannot be closed again unnoticed, it can either be provided that the shielding (at least without the appropriate aids) can no longer be closed position can be moved. Alternatively, the closing of the shield may be permitted, but the opening and/or closing activates a flag (at least not resettable without tools) which indicates that the shield has been opened.

An effect similar to the effect of the magnetic element can additionally or alternatively be realized, for example, by a different pretensioning of the shielding against a stop, for example via a spring device or the like.

Further preferred embodiments of the emergency actuation device according to the invention are characterized in that the shielding is designed in such a way that it is resistant to the effects of violence, ie it resists the effects of human violence that takes place without aids. For this purpose, the shielding can have, for example, a shielding element that shields the actuating element and is made of at least one metallic material and/or a plastic.

In further preferred embodiments of the emergency actuation device according to the invention, the locking device comprises a simple locking device, via which the shielding is locked. The locking device can be easily released via a corresponding key element, so that the shield can be removed and the actuating element can be operated (e.g. by authorized personnel for local access unlocking for cleaning or maintenance purposes) without destroying parts of the shield. This has the advantage that on the one hand a simple, robust and fail-safe solution is possible without the need for a separate power supply. On the other hand, a separate unlocking device for local access unlocking for authorized personnel can be omitted since this function (local access unlocking for cleaning or maintenance purposes) can be easily integrated into the emergency actuation device.

According to a further aspect, the present invention relates to an emergency operating device for a vehicle, in particular a rail vehicle, with an operating element for a control device and a shield assigned to the operating element, the control device, when the operating element is actuated from a rest position, opening an access device, in particular a door, to the Vehicle unlocked. In a closed state, the shield shields the actuating element, which is in its rest position, from unhindered access. For this purpose, the shielding can have, inter alia, an easily destructible element which is assigned to the actuating element in the closed state of the shielding in such a way that the actuating element is accessible for actuation after the destructible element has been destroyed. The locking device comprises a locking device, the locking device having a locked state in which the closed shielding is locked in position by the locking device. The lock device can be adjusted into an unlocked state by means of an associated key element, in which the shielding can be removed from the actuating element in order to release the actuation of the latter.

In all the cases described above, the emergency operating device can be designed in such a way that when the operating element is returned to its idle state, the access device is locked again, regardless of whether the previous actuation in an emergency resulted in a (possibly partial) destruction of the shielding or as part of a regular unlocking of access ( by authorized personnel) without destroying the shielding. As a result, a particularly simple design can be achieved.

In further variants of the invention, the circumstances of the actuation are determined or registered and, depending on this, the resetting of the actuation element is treated differently. Provision can be made for a corresponding sensor system to detect that the actuation element was actuated when the shielding was open non-destructively (by opening the lock device), and accordingly when the actuation element is returned to its idle state, the access device (provided it is properly closed) is locked again will.

In a particularly simple variant of the invention, the circumstances of the actuation are recorded via the lock device. For this purpose, the lock device can be connected to the control device in terms of signal technology, with the control device locking the access device again when the lock device is in the unlocked state when the actuating element is returned to its idle state.

The signals can be generated and transmitted between the lock device and the control device in any suitable manner. For example, mechanical, fluidic (i.e. pneumatic and/or hydraulic), electrical generation and transmission of the signals and any combination thereof can be provided. Particularly in configurations in which the access device is already locked pneumatically, the signal transmission between the lock device and the control device preferably also takes place at least partially, preferably essentially completely, pneumatically. As a result, a particularly simple design is possible without the use of additional energy sources.

If the preceding actuation took place in an emergency with a (possibly partial) destruction of the shielding, it may be sufficient to merely open the lock device (by authorized personnel) and, if necessary, the shielding in order to to enable the access device to be locked.

In the case of further variants, however, a further or separate reset signal may also be required for this. For this purpose, the lock device can, for example, be connected to the control device in terms of signals, with the control device locking the access device in the locked state of the lock device when the actuating element is reset to its idle state only if an additional reset signal is present (which was specified, for example, by authorized personnel in a suitable way).

The state of the lock device can be detected in any suitable manner. For example, when it is actuated, the lock device can actuate a corresponding switch or the like of the control device. The lock device preferably includes a detection device that can be connected to the control device for signals, in particular a sensor device or a switch device, the detection device detecting the locked state and/or the unlocked state of the lock device and supplying a corresponding signal to the control device.

The locking device and the key element can be designed in any suitable way which prevents the shielding from being opened quickly without a corresponding key element or special tool with a sufficiently high probability. Because of the nevertheless simple design, it is preferably provided that the key element is designed as a simple triangular element or as a square element.

The shield can be designed to be removable from the actuating element in any suitable manner (when the lock device is unlocked). The shielding is preferably designed as a pivotably hinged cover. This makes it easier for authorized personnel to open and close.

According to the invention, the shielding is designed as a cover pivoted about a first pivot axis and the actuating element is designed as a pivoted lever having a free first end and a second end in the region of which the actuating element is pivoted about a second pivot axis. The first pivot axis and the second pivot axis run essentially parallel to one another and the free first end of the actuating element is arranged closer to the first pivot axis than the second end in its rest position. This is advantageous with regard to avoiding accidental unlocking, since the shielding first has to be opened by a considerable angle (with the opposite pivoting direction to the pivoting lever) in order to be able to grip and actuate the pivoting lever at all.

The shield can be designed in any suitable way. So it can be designed as a one-piece or multi-piece cover.

As mentioned, the shielding can have an easily destructible element which is assigned to the actuating element in the closed state of the shielding in such a way that the actuating element is accessible for actuation after the destructible element has been destroyed. In this case, the destructible element can be formed by a transparent pane, in particular a glass pane. This results in particularly simple configurations.

The actuator can also be configured in any suitable manner that allows a passenger to unlock with normal effort. The actuating element is preferably formed by a pivoting lever, which is in particular articulated at the end.

Furthermore, the emergency actuation device can be attached to the vehicle in any suitable manner. Their components can be attached individually or in assemblies inside the vehicle (but possibly also on the outside of the vehicle). However, designs that are particularly easy to assemble are characterized in that the actuating element is arranged in a housing to which the shielding is attached.

The present invention also relates to a vehicle, in particular a rail vehicle, with a car body that has an access device, in particular a door or a window, and an emergency actuation device according to the invention, the emergency actuation device being assigned to the access device for actuating the access device. The variants and advantages described above can hereby be realized to the same extent, so that reference is made to the above explanations in this regard.

First embodiment

The following is with reference to the Figures 1 and 2 a first preferred exemplary embodiment of the rail vehicle 101 according to the invention is described, which has a vehicle longitudinal axis 101.1. For easier understanding of the following explanations, a vehicle coordinate system x,y,z is given in the figures, in which the x coordinate represents the longitudinal direction of the rail vehicle 101, the y coordinate represents the transverse direction of the rail vehicle 101 and the z coordinate represents the vertical direction of the Rail vehicle 101 denote.

the figure 1 shows a schematic view of the rail vehicle 101. The vehicle 101 comprises a car body 102, which is supported in the region of each of its two ends on a chassis. Access to the interior of the car body 102 takes place, among other things, via an access device in the form of a door 103. A preferred variant of the emergency actuating device 104 according to the invention is arranged in the car body 102, as prescribed, for example, in Europe by the TSI mentioned at the outset.

The door 103 can be unlocked locally via the emergency actuation device 104 in order to then open it by hand. On the one hand, this can be necessary if the passengers want to leave the vehicle 101 in an emergency. It may also be desirable for such a local unlocking and manual door opening to be able to be carried out in a simple manner by appropriately authorized personnel in the event of cleaning or maintenance of the vehicle 101 .

How in particular figure 2 can be seen, the emergency actuation device 104 comprises an actuation element in the form of a pivoted lever 105, which, when actuated, unlocks the door 103. For this purpose, the pivoting lever 105 designed as a conventional emergency handle can be grasped by a handle 105.1 in the area of its free, first end and then used to unlock the door 103 from its in figure 2 illustrated rest position can be pivoted out about its pivot axis 105.2, about which it is pivoted in the region of its second end to a housing 106, which in turn is attached to the structure of the car body 102 in the vicinity of the door 103.

The pivoting movement of the emergency handle 105 is detected by a suitable detection element 105.3 (for example a switch, a valve or the like) and triggers a corresponding signal to a control device in the form of a door control 107, which causes the door 103 to be unlocked.

The signal can be transmitted from the emergency handle 105 to the control device 107 and further to the door 103 in any suitable manner. Mechanical, electrical and fluidic principles of action can be used individually or in any combination. In the present example, a pneumatic actuation of the door 103 is provided, so that a pneumatic operating principle is also used for the respective signal transmission. This has the advantage that no additional energy source has to be provided for signal transmission.

In order to avoid accidental or undesired actuation of the emergency handle in accordance with the provisions of the mentioned TSI, the emergency actuation device 104 comprises a shield in the form of a cover 108 which, in a closed state, shields the emergency handle 105, which is in its rest position, from unhindered access.

The cover 108 is articulated on the housing 106 so that it can pivot about a pivot axis 108.1 in such a way that it is in its (in figure 2 illustrated) closed state covers the entire housing side of the housing 106 facing it. A first closing element 109.1 of a locking device in the form of a locking device 109 is arranged on the end of the cover 108 facing away from the pivot axis 108.1, which, when the cover 108 is in the closed state, can interact with a second locking element 109.2 of the locking device 109 arranged on the housing 106 in order to secure the cover 108 to lock in its closed state and thus shield the emergency handle against unhindered access.

In the present example, a key element (not shown) in the form of a simple square socket wrench is provided for locking and unlocking the lock device 109, which interacts with the square profile of the first locking element 109.1 in order to bring the first locking element 109.1 and the second locking element 109.2 into engagement with one another or to open them .to solve this intervention.

The cover 108 has an easily destructible element in the form of a glass pane 108.2, which is held in a frame 108.3 of the cover 108. When cover 108 is closed, glass pane 108.2 is assigned to emergency handle 105, which is in its rest position, in such a way that emergency handle 105 can be pivoted out of its rest position (second Actuation as defined by the TSI) to trigger unlocking of the door 103.

The design of the emergency operating device 104 described above also makes it possible for appropriately authorized personnel to unlock the locking device 109 using an associated key element and to slide the cover 108 into the (in figure 2 shown in dashed lines) open position, in which the emergency handle 105 can be operated to unlock the door 103 without destroying the glass pane 108.2.

For the unlocking of the lock device 109 only a short one-time unlocking action is necessary, namely a single movement. This makes it possible to also use the emergency operating device 104 for a regular local unlocking of the door 103, as may be desirable or necessary, for example, for the purpose of maintaining and/or cleaning the vehicle 101. Advantageously, it is no longer necessary to provide a corresponding separate device for the purpose of regular local unlocking.

In the present example, the (first) pivot axis 108.1 of the cover 108 and the (second) pivot axis 105.2 of the emergency handle 105 run parallel to one another, so that their pivot movements take place in a common plane. It goes without saying, however, that in other variants of the invention it can also be provided that the two pivoting planes run transversely, in particular perpendicularly, to one another. Such an arrangement of the pivot axes or pivot planes has the advantage that the cover must first be deliberately opened by a specific pivot angle (which varies depending on the position of the pivot planes) before the emergency handle can be actuated, so that erroneous actuation is less likely. In the present example, this safeguard is achieved in that the handle 105.1 is arranged between the two pivot axes 108.1 and 105.2, so that pivoting movements in opposite directions are required when the cover 108 is opened or when the emergency handle 105 is actuated.

In the present example, the door 103 is locked again as soon as the emergency handle 105 has been pivoted back into its rest position. It can of course be provided here that the control device 107 checks in a suitable manner whether the door 103 is again in its correct closed position, and only in this case is the locking of the door 103 actuated.

It goes without saying, however, that in other variants of the invention it can also be provided that when the emergency handle 105 is reset, it is taken into account whether it was actuated in an emergency situation with the destruction of the glass pane 108.2 or as part of a regular unlocking of the door with the cover 108 open , as will be described below in connection with the second exemplary embodiment.

Second embodiment

The following is with reference to the Figures 1 and 2 a second preferred exemplary embodiment of the rail vehicle 101 according to the invention or of the emergency operating device 104 according to the invention is described. The only difference from the first exemplary embodiment is that the emergency actuation device 104 has a further detection device, as is shown in figure 2 is indicated by the dashed contour 110.

Based on a signal transmitted by the detection device 110 or present at the detection device 110, the control device 107 detects whether the lock device 109 is in a locked state or in an unlocked state.

If the locking device 109 is in an unlocked state, it is assumed that it was unlocked by an appropriately authorized party using a suitable key element. In this case, the door 103 is locked again when the emergency handle 105 is returned to its rest position.

If this is not the case, if the lock device 109 is in a locked state, it is assumed that the emergency handle 105 was actuated in an emergency situation, destroying the glass pane 108.2. In this case, the control device must be given a separate reset signal via a separate signal line 111 in order to lock the door 103 again when the emergency handle 105 is returned to its rest position.

However, it goes without saying that to lock the door 103 again, it can also be sufficient for the locking device 109 to be brought into its unlocked state before the emergency handle 105 is reset, in order to achieve the signal constellation described above.

It is further understood that the detection device 110 can be configured in any suitable manner. In the present example, it preferably also operates pneumatically (for example via a simple pneumatic switch which is also actuated when the lock device 109 is actuated) in order to obviate the need for an additional energy source.

Third embodiment

The following is with reference to the figures 1 , 3 and 4 a third preferred exemplary embodiment of the rail vehicle 101 according to the invention or the emergency operating device 204 according to the invention, which can be used in place of the emergency operating device 104 in the rail vehicle 101. The emergency actuation device 204 corresponds to the emergency actuation device 104 in terms of its basic design and mode of operation, so that only the differences will be discussed here. In particular, similar components are provided with reference numbers increased by 100. Unless otherwise specified below, express reference is made to the above statements with regard to the features of these components.

The difference from the first embodiment is essentially only in the design of the shield 208. Like the Figures 3 and 4 refer to is, the shield 208 in turn comprises a cover 208.4, which is in an in figure 3 illustrated closed state shields the emergency handle 105, which is in its rest position, against unhindered access.

For this purpose, the cover 208.4 is pivoted about a pivot axis 208.1 on a holding element 208.5. The holding element 208.5 is in turn attached to the housing 206 of the emergency actuation device 204. The dimensions are chosen so that the cover 208.4 is pivoted on the housing 206 of the emergency operating device 204 in such a way that it is in its (in figure 3 shown) closed state covers a sufficiently large part of the housing side of the housing 206 facing it in order to cover the grip area 105.1 of the emergency lever 105 and thus to shield against unhindered access.

To lock the shield 208 in its closed state, a locking element (not shown) in the form of a simple wire seal 209 is provided in the present example, the sealing wire 209.1 of which is guided through a hole 208.6 in the cover 208.4 and an associated hole in the emergency lever 105. The ends of the sealing wire 209.1 are then sealed in a conventional manner using a lead seal 209.2.

In the present example, the cover 208.4 is designed as a simple element that cannot be destroyed by normal human violence without aids (such as tools or the like). In the present example it is designed as a simple, flat element made of sheet steel with a protective paint finish. However, it goes without saying that any other correspondingly resistant elements can also be used in other variants of the invention. Furthermore, it goes without saying that the cover can also have any other shape in other variants of the invention. In particular, it can have a recessed grip or the like in order to facilitate its operation.

In order to actuate the emergency handle 105, the cover 208.4 must first be pivoted upwards into its open position in a single action (unlocking action) by destroying the wire seal 109 (first actuation within the meaning of the TSI), so that the emergency handle 105 is then released and can be pivoted out of its rest position (second actuation within the meaning of the TSI) to trigger unlocking of door 103.

As figure 4 As can be seen, the cover 208.4 has a magnetic element 209.3 on its side facing the emergency handle 105, which interacts with the emergency handle 105 and/or the housing 206 and holds the cover 208.4 in its closed position in order to avoid noise.

It goes without saying that the force effect of the magnetic element 209.3 can also be chosen so large in other variants of the invention that it is sufficient to assume the function of locking the cover 208.4 in its closed position against unintentional actuation. The seal can then be omitted and only the above-described marking can be provided, which indicates that the cover 208.4 has been opened.

This design makes it possible, for example, for authorized personnel to pivot the cover 208.4 into the open position, in which the emergency handle 105 can be actuated to unlock the door 203. This makes it possible to also use the emergency operating device 204 for a regular local unlocking of the door 203, as may be desirable or necessary, for example, for the purpose of maintaining and/or cleaning the vehicle 201. Advantageously, it is no longer necessary to provide a corresponding separate device for the purpose of regular local unlocking. If necessary, provision can be made for the authorized personnel to reset the described marking using appropriate aids or tools.

It is also understood that in other variants of the invention a magnetic element can additionally or alternatively also be arranged on the emergency handle and/or the housing in order to achieve the desired effect of force. Likewise, for example, in the area of the pivot axis 208.1, a spring element can be additionally or alternatively provided, which brings about a corresponding prestressing of the cover 208.4 against the housing 206.

In the present example, the (first) pivot axis 208.1 of the cover 208.4 and the (second) pivot axis 105.2 of the emergency handle 105 run parallel to one another, so that their pivot movements take place in a common plane. It goes without saying, however, that in other variants of the invention it can also be provided that the two pivoting planes run transversely, in particular perpendicularly, to one another. Such an arrangement of the pivot axes or pivot planes has the advantage that the cover must first be deliberately opened by a specific pivot angle (which varies depending on the position of the pivot planes) before the emergency handle can be actuated, so that erroneous actuation is less likely. In the present example, this safeguard is achieved in that the handle 105.1 is arranged between the two pivot axes 208.1 and 105.2, so that pivoting movements in opposite directions are required when the cover 208.4 is opened or when the emergency handle 105 is actuated.

Like that one in particular figure 4 can be seen, the holding element 208.5 is simply fastened to the housing 206 via fastening elements 208.8. This design has the advantage that the cover 208.4 can be easily adapted to the dimensions of the housing 206. In particular, the fastening elements for the housing 206 that are present in any case can be used for the fastening elements 208.8 (which fix the housing 206 to the car body).

The present invention has been described above with reference to examples in which the shield is designed as a one-piece or two-piece assembly.
