Description

[0001] VEHICLE CELL AND PROTECTED VEHICLE

[0002] The present invention relates to a vehicle cell for a protected vehicle and a protected vehicle with such a vehicle cell.

[0003] An armored vehicle comprises a vehicle cell that is protected against ballistic attack. When constructing such a protected vehicle, it may be necessary to mount and attach additional components such as bulkheads, partitions, shelving structures, or the like within the vehicle cell. Such additional components are generally very rigid. Due to their rigidity, these additional components can react by buckling when large forces are applied. This can, for example, lead to equipment stored in or on the additional component being greatly accelerated. This in turn can lead to this equipment being accelerated to such an extent that it acts like projectiles within the vehicle cell. It must therefore be ensured that if the armored vehicle is bombed, no energy, and therefore no acceleration, is introduced into the additional components.

[0004] According to internal company findings, such additional components can be suspended decoupled from the floor of the vehicle cell. Additional components in the form of bulkheads or partitions can be curved. Furthermore, it is possible to split them and weld them together in an overlapping manner, so that any buckling or deformation takes place within a controllable area. However, the aforementioned measures can result in a comparatively complex and heavy construction being required. Furthermore, the aforementioned solutions do not offer any conclusive guarantee that energy will not be introduced into the additional components when the additional components are connected to the vehicle cell. Curved bulkheads or partitions also require more space, which can also complicate the design of adjacent components in their immediate vicinity. This needs to be improved.

[0005] Against this background, it is an object of the present invention to provide an improved vehicle cell for a protected vehicle.

[0006] Accordingly, a vehicle cell for a protected vehicle is proposed. The vehicle cell comprises an assembly having a structural component, an additional component positioned within the vehicle cell, and a connecting and decoupling device by means of which the additional component is connected to the structural component. The connecting and decoupling device is configured to mechanically decouple the additional component from the structural component in the event of deformation of the structural component resulting from a deformation of the structural component, and the connecting and decoupling device is a hook-and-loop fastener.

[0007] Because the connecting and decoupling device is designed to mechanically decouple the additional component from the structural component during detonation, it can reliably prevent forces and accelerations resulting from the deformed structural component from being transferred to the additional component. Equipment stored on or in the additional component cannot therefore act as projectiles.

[0008] The arrangement can also be referred to as a protective arrangement. Accordingly, the terms "arrangement" and "protective arrangement" are interchangeable. A "protected" vehicle is understood here to be a vehicle that is protected against gunfire, booby traps, improvised explosive devices (IEDs), mines, any explosive devices, or the like. The vehicle may be armored for this purpose.

[0009] The arrangement can comprise multiple structural components. The number of structural components is fundamentally arbitrary. However, reference is made below to only one structural component. The structural component can also be referred to as a structural component. The structural component can be part of the vehicle's vehicle cell. The arrangement can thus be part of the vehicle cell. Furthermore, the vehicle cell itself can function as a structural component. In other words, the vehicle cell itself can be the structural component.

[0010] The vehicle cell preferably encloses an interior space in which crew members or a vehicle crew can be located. The additional component is located within this interior space or within the vehicle cell. However, this is not mandatory. The additional component can also be located on the outside of the vehicle cell.

[0011] For example, the structural component is a wall of the aforementioned vehicle cell. Accordingly, the term "structural component" can be replaced by the term "wall," and vice versa. The vehicle cell preferably comprises two structural components arranged parallel to and spaced from one another in the form of side walls, in particular a first side wall and a second side wall, a structural component designed as a floor, and a structural component designed as a ceiling or roof. In this case, a "structural component" is understood to mean, in particular, a load-bearing component of the protected vehicle.

[0012] The structural component can be made of a metallic material. For example, the structural component can be or comprise a steel plate or an aluminum plate. However, the structural component can also comprise composite materials. The structural component can be changed from an undeformed state to a deformed state using an explosive device that generates a pressure wave. The deformation is elastic and / or plastic. This means that the deformation can be at least partially reversed.

[0013] The additional component can be a shelf structure, a bulkhead, a partition, armor plating, or the like. The additional component can also be a walkway that can be placed within the vehicle cell. The additional component can also be referred to as an additional component. In particular, the additional component can be designed to accommodate equipment. In this case, the additional component is preferably a shelf or a shelf structure.

[0014] The connecting and decoupling device connects the additional component to the structural component. The additional component thus bears a load on the structural component. In other words, the structural component supports the additional component. The connection between the additional component and the structural component can be direct or indirect. "Direct" in this context means, in particular, that the connecting and decoupling device connects the additional component directly to the structural component. Thus, no additional parts or components are provided between the additional component and the connecting and decoupling device, or between the connecting and decoupling device and the structural component.

[0015] In contrast, "indirectly" means, in particular, that the connecting and decoupling device connects the additional component indirectly to the structural component. In this case, in contrast to the direct connection between the additional component and the connecting and decoupling device or between the connecting and decoupling device and the structural component, additional components or parts may be provided. These additional components or parts may, for example, be support elements, which will be explained later. These additional components or parts may each be part of the additional component or part of the structural component.

[0016] The connection between the additional component and the structural component can be materially bonded, form-fitted, and / or force-fitted. In materially bonded connections, the connecting partners are held together by atomic or molecular forces. Materially bonded connections are non-detachable connections that can only be separated by destroying the connecting elements and / or the connecting partners. In this case, the connecting and decoupling device can be, for example, an adhesive bond or a bonded joint.

[0017] A positive connection is created by the interlocking or interlocking of at least two connecting partners. A positive connection can be released and re-established as often as desired. The connecting and decoupling device is a hook-and-loop fastener or a hook-and-loop connection. The connecting and decoupling device can therefore be referred to as a hook-and-loop fastener or a hook-and-loop connection.

[0018] A "Hook and Loop fastener" or "Hook and Loop connection" is understood here as a fastening device based on the principle of burdock, particularly one that can be released as often as required. The bionic implementation of such a hook and loop fastener or hook and loop connection can take the form of two band-like or strip-like components or elements, one of which has flexible hooks, hook sections, or barbs, and the other component has flexible loops or loop sections. When pressed together, the two components form a resilient yet reversible quick-release fastener.

[0019] In the event that the connecting and decoupling device is a hook-and-loop fastener or a hook-and-loop connection, a further development of the arrangement for the protected vehicle is proposed. In this case, the arrangement comprises a structural component, an additional component, and a hook-and-loop connection by means of which the additional component is connected to the structural component. The hook-and-loop connection is designed to mechanically decouple the additional component from the structural component in the event of deformation of the structural component resulting from a deformation of the structural component. In this case, the hook-and-loop connection is opened or released in particular upon the deformation of the structural component or upon the deformation of the structural component.

[0020] A force-locking connection, on the other hand, requires a normal force acting on the surfaces to be joined. Force-locking connections can be achieved through frictional engagement. Mutual displacement of the surfaces to be joined is prevented as long as the counterforce caused by static friction is not exceeded. A force-locking connection can, for example, be a magnetic force connection. In this case, the connecting and decoupling device exhibits magnetic properties, at least in sections.

[0021] The fact that the connecting and decoupling device is designed to "mechanically decouple" the additional component from the structural component is to be understood in the present case as meaning that the connecting and decoupling device automatically or independently releases the connection between the additional component and the structural component when the structural component is subjected to wringing as a result of the deformation of the structural component, so that accelerations and / or forces resulting from the deformation of the structural component cannot be transmitted to the additional component or can be transmitted to it at least only to a reduced extent.

[0022] The connecting and decoupling device thus functions as a separation point or predetermined breaking point provided between the structural component and the additional component. Accordingly, the terms "connecting and decoupling device" and "predetermined breaking point" can be interchanged at will. The mechanical decoupling of the additional component from the structural component occurs, in particular, by the fact that the materially bonded, positively locking, and / or force-locking connection created by the connecting and decoupling device is automatically released when the structural component is ruptured.

[0023] In this case, "automatic" or "independent" means in particular that the connecting and decoupling device is not controlled by means of an external control or the like, but that the connecting and decoupling device reacts autonomously to the deformation of the structural component when the structural component is wrecked and separates the additional component from the structural component or mechanically decouples it from it.

[0024] According to one embodiment, the additional component of the connecting and decoupling device is positively connected to the structural component.

[0025] As previously mentioned, a positive connection can be released and restored as often as desired. This means, in particular, that after the structural component has been wrung out, the additional component can be reconnected to the structural component. Both the release and the connection can be carried out either tool-free or without the use of tools. A positive connection is thus created between the additional component and the structural component with the aid of the connecting and decoupling device. As previously mentioned, the connection between the additional component and the structural component can also be materially bonded and / or force-fitted. Any combination of a materially bonded, positive-fit, and / or force-fit connection can also be provided.According to a further embodiment, the connecting and decoupling device has a first connecting and decoupling element assigned to the structural component and a second connecting and decoupling element assigned to the additional component, wherein the first connecting and decoupling element and the second connecting and decoupling element engage in a form-fitting manner for connecting the additional component to the structural component.

[0026] The first connecting and decoupling element and the second connecting and decoupling element together form the connecting and decoupling device. In the event that the connecting and decoupling device establishes a materially bonded connection between the structural component and the additional component, the first connecting and decoupling element and the second connecting and decoupling element can be part of an adhesive bond that forms the connecting and decoupling device. Alternatively, at least one of the two connecting and decoupling elements can be a magnet, in particular a permanent magnet. The first connecting and decoupling element can also be referred to as the first connecting and separating element. Accordingly, the second connecting and decoupling element can also be referred to as the second connecting and separating element.

[0027] According to a further embodiment, the positive connection between the first connecting and decoupling element and the second connecting and decoupling element releases automatically as a result of the deformation of the structural component in order to mechanically decouple the additional component from the structural component.

[0028] In particular, the structural component moves toward the additional component when it is deformed. This relative movement releases the connection between the first connecting and decoupling element and the second connecting and decoupling element, so that the additional component is mechanically decoupled from the structural component. The release of the connection between the two connecting and decoupling elements occurs, as previously mentioned, automatically or independently, so that no external control of the connecting and decoupling device is required. The connection between the first connecting and decoupling element and the second connecting and decoupling element can be released in such a way that there is no longer any contact between the first connecting and decoupling element and the second connecting and decoupling element. However, this is not absolutely necessary.The connection between the first connecting and decoupling element and the second connecting and decoupling element can also be released in such a way that there is still a touching contact between the first connecting and decoupling element and the second connecting and decoupling element.

[0029] According to a further embodiment, during the deformation of the structural component, shear forces oriented opposite to and parallel to one another act on the first connecting and decoupling element and on the second connecting and decoupling element in order to release the positive connection between the first connecting and decoupling element and the second connecting and decoupling element.

[0030] In other words, the connecting and decoupling device or the connecting and decoupling elements are subjected purely or exclusively to shear forces. The shear forces shear the connection between the first connecting and decoupling element and the second connecting and decoupling element, causing them to separate from each other in order to mechanically decouple the additional component from the structural component. According to a further embodiment, the first connecting and decoupling element is oriented perpendicular to the structural component, while the second connecting and decoupling element is oriented perpendicular to the additional component.

[0031] However, the first connecting and decoupling element can also be oriented obliquely to the structural component. Accordingly, the second connecting and decoupling element can also be oriented obliquely to the additional component. The arrangement is preferably assigned a coordinate system with a width direction or x-direction, a height direction or y-direction, and a depth direction or z-direction. The directions are oriented perpendicular to one another. Preferably, the first connecting and decoupling element and the second connecting and decoupling element run along the y-direction. Accordingly, the structural component and the additional component can each run along the z-direction. The structural component and the additional component can thus be placed parallel to one another and spaced apart from one another.In the present case, "perpendicular" is to be understood as meaning in particular an angle of 90° ± 10°, preferably of 90° ± 5°, more preferably of 90° ± 3°, more preferably of 90° ± 1°, more preferably of exactly 90°.

[0032] According to a further embodiment, the first connecting and decoupling element has engagement sections, wherein the second connecting and decoupling element has counter-engagement sections corresponding to the engagement sections, and wherein the engagement sections are designed to engage positively in the counter-engagement sections.

[0033] The first connecting and decoupling element can have any number of engagement sections. In particular, the first connecting and decoupling element is assigned a base section, from which any number of engagement sections extend on a front side thereof. The engagement sections can be arranged in a grid or pattern. "Grid-like" or "pattern-like" in the present case means that the engagement sections can be arranged in rows and columns. The base section can be connected, in particular glued, to the structural component via a rear side of the base section. The second connecting and decoupling element accordingly also comprises such a base section, from whose front side any number of counter-engagement sections extend. The number of counter-engagement sections is arbitrary.The number of engagement sections and the number of counter-engagement sections do not have to be identical. The counter-engagement sections are arranged in a pattern or grid on the base section of the second connecting and decoupling element. The second connecting and decoupling element can be connected, in particular glued, to the additional component on a rear side facing away from the counter-engagement sections.

[0034] According to a further embodiment, the engagement portions and / or the counter-engagement portions are elastically deformable.

[0035] In particular, the engagement sections and / or the counter-engagement sections are resiliently deformable. This means, in particular, that the engagement sections and / or the counter-engagement sections can be brought from an undeformed state into a deformed state by applying a force. As soon as this force is no longer effective, the engagement sections and / or the counter-engagement sections automatically return from the deformed state to the undeformed state. Either only the engagement sections, only the counter-engagement sections, or both the engagement sections and the counter-engagement sections are elastically deformable. According to a further embodiment, the engagement sections are hook-shaped and the counter-engagement sections are loop-shaped, or vice versa.

[0036] "Or vice versa" in this case means, in particular, that the engagement sections can be loop-shaped and the counter-engagement sections can be hook-shaped. However, the geometries of the engagement sections and the counter-engagement sections are fundamentally arbitrary. The engagement sections and the counter-engagement sections, in particular, merely have the property of being able to interlock in a form-fitting manner in order to connect the first connecting and decoupling element and the second connecting and decoupling element to one another. The engagement sections can also be referred to as hook sections or barb sections. Accordingly, the counter-engagement sections can be referred to as loop sections.

[0037] According to a further embodiment, the arrangement further comprises a first support element connected to the structural component, which supports the first connecting and decoupling element, and a second support element connected to the additional component, which supports the second connecting and decoupling element.

[0038] For example, the first connecting and decoupling element is glued, riveted and / or screwed to the first support element. Accordingly, the second connecting and decoupling element can also be glued, riveted and / or screwed to the second support element. For example, the first support element is welded, screwed and / or riveted to the structural component. The second support element can be welded, screwed and / or riveted to the additional component. The connection between the structural component and the additional component is thus established indirectly via the first support element, the connecting and decoupling elements and the second support element. However, the support elements are optional. The first connecting and decoupling element can also be connected directly to the structural component. Accordingly, the second connecting and decoupling element can also be connected directly to the additional component.

[0039] According to a further embodiment, the first support element is oriented perpendicular to the structural component, wherein the second support element is oriented perpendicular to the additional component.

[0040] However, the orientation of the support elements is fundamentally arbitrary. The first connecting and decoupling element is preferably oriented parallel to the first support element and thus perpendicular to the structural component. The second connecting and decoupling element is preferably oriented parallel to the second support element and thus perpendicular to the additional component. Furthermore, the first support element can also be oriented perpendicular to the additional component, and the second support element can be oriented perpendicular to the structural component.

[0041] According to a further embodiment, the first carrier element and the second carrier element are oriented parallel to each other, wherein the first connecting and decoupling element and the second connecting and decoupling element are arranged between the first carrier element and the second carrier element.

[0042] "Parallel to one another" in this context means that the first support element and the second support element can each span a plane that is arranged parallel to one another and spaced apart from one another. The aforementioned planes can be arranged parallel to a plane of the coordinate system spanned by the x-direction and the y-direction. The first support element and / or the second support element can be plate-shaped or sheet-shaped. Furthermore, a protected vehicle with such a vehicle cell is proposed.

[0043] The protected vehicle can comprise several such arrangements. The protected vehicle can be a military vehicle, in particular a military utility vehicle. The protected vehicle can therefore also be referred to as a military vehicle or a military utility vehicle. The protected vehicle comprises the aforementioned vehicle cell. The vehicle cell can also be referred to as a passenger cell, crew cell, or crew cell. The vehicle cell is protected against ballistic missiles, booby traps, USB, mines, or the like. The vehicle cell is armored. The vehicle cell encloses an interior space as mentioned above, in which crew members can be located. The interior space can be divided into several sections or spaces that can be separated from one another. For example, the interior space can be divided into an engine room, a crew compartment, and / or a driver's compartment. Partition walls or bulkheads can be provided for this purpose.These can function as additional components. Furthermore, the vehicle cell can be at least partially or completely interchangeable in a modular manner. In this case, the vehicle can have different mission modules that can be interchanged at will. An example of such a mission module is a medical module. The assembly can be part of such a mission module. The protected vehicle can be a wheeled vehicle. Alternatively, the protected vehicle can also be a tracked vehicle. The protected vehicle can have all-wheel drive.

[0044] According to one embodiment, the structural component is part of a vehicle cell of the protected vehicle. In particular, the vehicle cell is constructed from several such structural components, which are firmly connected to one another, for example, welded, screwed, and / or riveted. The structural component can be a wall of the vehicle cell. For example, as previously mentioned, the vehicle cell has two side walls arranged parallel to and spaced from one another, which are structural components, a floor, which is also a structural component, and a ceiling, which is also a structural component. However, the structural component is particularly preferably the floor of the vehicle cell. Accordingly, the term "structural component" can also be exchanged for the term "floor." In particular, the vehicle cell itself can also be a structural component to which the additional component is attached or to which several additional components are attached.

[0045] According to a further embodiment, the additional component is arranged within the vehicle cell.

[0046] Accordingly, the connecting and decoupling device is also preferably located within the vehicle cell. As previously mentioned, the vehicle cell encloses the interior. The additional component is accordingly arranged within the interior. However, as previously mentioned, the additional component can also be provided outside the vehicle cell. For example, the additional component can be attached to the outside of the vehicle cell as armor plating or the like. However, the additional component can also be a shelf structure, a bulkhead, a partition, or the like, as previously mentioned.

[0047] The embodiments and features described for the proposed vehicle cell apply accordingly to the protected vehicle and vice versa.

[0048] "One" in this case is not necessarily limited to a single element. Rather, multiple elements, such as two, three, or more, may also be included. Any other counting term used here should not be understood as implying a limitation to the exact number of elements mentioned. Rather, numerical deviations upwards and downwards are possible, unless otherwise stated.

[0049] Further possible implementations of the vehicle cell and / or the protected vehicle also include combinations of features or embodiments described above or below with regard to the exemplary embodiments that are not explicitly mentioned. In this case, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the vehicle cell and / or the protected vehicle.

[0050] Further advantageous configurations and aspects of the vehicle cell and / or the protected vehicle are the subject of the dependent claims and the exemplary embodiments of the vehicle cell and / or the protected vehicle described below. The vehicle cell and / or the protected vehicle are explained in more detail below using preferred embodiments with reference to the accompanying figures.

[0052] Fig. 2 shows a schematic sectional view of the protected vehicle according to the section line II -II of Fig. 1!

[0053] Fig. 3 shows a schematic sectional view of an embodiment of an arrangement for the protected vehicle according to Fig. 1!

[0054] Fig. 4 shows a further schematic sectional view of the arrangement according to Fig. 3; Fig. 5 shows the detailed view V according to Fig. 3; and

[0055] Fig. 6 shows a schematic view of an embodiment of a connecting and decoupling device for the arrangement according to Fig. 3.

[0056] In the figures, identical or functionally equivalent elements have been given the same reference numerals unless otherwise stated.

[0057] Fig. 1 shows a schematic side view of an embodiment of a protected vehicle 1. Fig. 2 shows a schematic sectional view of the protected vehicle 1 according to the section line II -II of Fig. 1. In the following, reference is made simultaneously to Figs. 1 and 2.

[0058] The protected vehicle 1 is referred to simply as a vehicle below. The vehicle 1 can be a military vehicle, in particular a military utility vehicle. The vehicle 1 can therefore also be referred to as a military vehicle or a military utility vehicle. The vehicle 1 comprises a protected passenger compartment or vehicle compartment 2. The vehicle compartment 2 is protected against gunfire, booby traps, improvised explosive devices (IEDs), mines, or the like. The vehicle compartment 2 can be a vehicle hull and can therefore also be referred to as such. The terms "vehicle compartment" and "vehicle hull" are therefore interchangeable.

[0059] The vehicle cell 2 is armored. The vehicle cell 2 encloses an interior space 3 in which crew members can be located. The interior space 3 is accessible from an area 4 of the vehicle 1 via doors and / or hatches (not shown). The interior space 3 can be divided into several sections or spaces, which can be separated from one another. For example, the interior space 3 can be divided into an engine room, a crew compartment, and / or a driver's compartment. However, this is not mandatory.

[0060] Furthermore, the vehicle cell 2 can be at least partially or completely interchangeable in a modular manner. In this case, the vehicle 1 can have different mission modules that can be interchanged at will. An example of such a mission module is a medical module. However, this modular structure explained above is arbitrary.

[0061] The vehicle 1 can be a wheeled vehicle. Alternatively, the vehicle 1 can also be a tracked vehicle. The vehicle 1 comprises several wheel axles on which wheels 5, 6 are provided. For example, four wheels 5, 6 are provided, namely two front wheels and two rear wheels. The number of wheel axles is fundamentally arbitrary. For example, two wheel axles or three wheel axles can be provided. Preferably, the vehicle 1 comprises an all-wheel drive system. This means that all wheel axles are driven.

[0062] The vehicle 1 is assigned a coordinate system with a width direction or x-direction x, a height direction or y-direction y, and a depth direction or z-direction z. The directions x, y, z are oriented perpendicular to one another. A direction of gravity g can be oriented opposite to the y-direction y. The vehicle 1 can move along a direction of travel F and opposite to the direction of travel F on a floor or subsurface 7. The direction of travel F can be oriented opposite to the x-direction x.

[0063] As Fig. 2 shows, the vehicle cell 2 comprises several structural components 8 to 11. The structural components 8 to 11 can also be referred to as structural components. The terms "structural component" and "structural component" are therefore interchangeable. A first structural component 8, a second structural component 9, a third structural component 10, and a fourth structural component 11 can be provided. The structural components 8 to 11 are firmly connected to one another, for example, welded, riveted, and / or screwed, and together can form the vehicle cell 2. The structural components 8 to 11 can be walls of the vehicle cell 2. Therefore, the term "structural component" can be replaced by the term "wall." In this context, a "structural component" is understood to mean, in particular, a load-bearing component or a load-bearing component of the vehicle 1.

[0064] For example, structural components 8 to 11 are steel plates. However, structural components 8 to 11 may also comprise composite materials. The aforementioned doors and / or hatches may be provided on structural components 8 to 11 or on at least some of the structural components 8 to 11, by means of which the interior space 3 is accessible from the surroundings 4.

[0065] The first structural component 8 can be a first side wall of the vehicle cell 2. Therefore, the terms "first structural component" and "first side wall" can be interchanged as desired. The second structural component 9 can be a second side wall of the vehicle cell 2. Therefore, the terms "second structural component" and "second side wall" can be interchanged as desired. Viewed along the z-direction z, the first structural component 8 and the second structural component 9 are arranged at a distance from one another. The first structural component 8 is arranged parallel to the second structural component 9.

[0066] The third structural component 10 can be a floor of the vehicle cell 2. Therefore, the terms "third structural component" and "floor" can be interchanged as desired. The fourth structural component 11 can be a roof of the vehicle cell 2. Therefore, the terms "fourth structural component" and "roof" can be interchanged as desired. Viewed along the y-direction y, the third structural component 10 and the fourth structural component 11 are arranged at a distance from one another. The third structural component 10 is arranged parallel to the fourth structural component 11. The structural components 8, 9 are oriented perpendicular to the structural components 10, 11. Furthermore, the vehicle cell 2 can also comprise a front wall (not shown) and a rear wall (not shown).

[0067] The third structural component 10, which, as previously mentioned, can form a floor of the vehicle cell, can have a V-shaped geometry in cross-section (not shown). Furthermore, the third structural component 10 can also be designed as a double floor. In this case, two floors are provided, which are arranged spaced apart from one another along the y-direction y.

[0068] The first structural component 8 has an inner side 12 facing the interior space 3 and an outer side 13 facing the environment 4. The second structural component 9 has an inner side 14 facing the interior space 3 and an outer side 15 facing the environment 4. The third structural component 10 has an inner side 16 facing the interior space 3 and an outer side 17 facing the environment 4. The fourth structural component 11 has an inner side 18 facing the interior space 3 and an outer side 19 facing the environment 4. All inner sides 12, 14, 16, 18 face towards the interior space 3 and away from the environment 4. All outer sides 13, 15, 17, 19 face towards the environment 4 and away from the interior space 3.

[0069] During operation of the vehicle 1, it can be detonated using an explosive device 20. The explosive device 20 can be a mine, an IED, or, for example, part of a recoilless anti-tank weapon (Rocket-Propelled Grenade, RPG). In the present example according to Fig. 2, the explosive device 20 can be at least partially concealed in the ground 7. However, this is not absolutely necessary. If the vehicle 1 drives over or past the explosive device 20, the explosive device 20 is triggered or ignited and generates a pressure wave 21, which in the present case acts on the third structural component 10 and plastically and / or elastically deforms it towards the interior 3. The pressure wave 21 can also be referred to as a blast. The pressure wave 21 can also act on any other structural component 8, 9, 11. In this case, the explosive device 20 can, for example, be placed on the side of the vehicle 1.The explosive device 20 can be triggered either contact-free or contact-based. In the latter case, for example, one of the wheels 5, 6 rolls over the explosive device 20.

[0070] Protection against the aforementioned explosion of the vehicle 1 is crucial to protect crew members in the interior 3 from the effects of the pressure wave 21. For this reason, the vehicle cell 2 is adapted so that it can absorb as much energy from the pressure wave 21 as possible and does not transmit it into the interior 3. This can be achieved, for example, by plastic deformation of the vehicle cell 2.

[0071] When designing the vehicle 1 or the vehicle cell 2, particular attention is paid to the implementation of additional components or additional parts, such as bulkheads, partitions, shelf structures or the like, and their attachment to the structural components 8 to 11 of the vehicle cell 2.

[0072] For example, shelving structures for storing equipment or any components are inherently rigid structures. Due to their rigidity, such shelving structures react with buckling when large forces are applied, which can lead to the acceleration of equipment stored in the shelving structure. This can cause these pieces of equipment to accelerate so much that they act like projectiles within the interior 3. Therefore, in the event of an explosion against the vehicle 1, it must be ensured that no energy, and thus no acceleration, is transmitted to the aforementioned additional components.

[0073] According to internal company knowledge, such additional components, such as shelves, are suspended decoupled from a floor of the vehicle cell 2, in this case the third structural component 10. For example, the additional components can be suspended from the fourth structural component 11. Additional components in the form of bulkheads or partitions can be bent. Furthermore, it is possible to split them and weld them overlapping, so that the bending or deformation occurs within a controllable area.

[0074] The previously mentioned decoupling of these additional components from structural components 8 to 11 can result in structural components 8 to 11 becoming comparatively complex and heavy. Furthermore, such solutions do not provide complete assurance that the connection of the additional components to structural components 8 to 11 will not result in energy being transferred into the additional components in the event of an explosion of vehicle 1. Curved bulkheads or partitions require more space, which can also complicate the design of adjacent components in the immediate vicinity. This must be improved.

[0075] Fig. 3 shows a schematic sectional view of an arrangement 22 for the vehicle 1. Fig. 4 shows a further sectional view of the arrangement 22. Fig. 5 shows the detailed view V according to Fig. 3. In the following, reference is made simultaneously to Figs. 3 to 5.

[0076] The arrangement 22 is part of the vehicle cell 2. The arrangement 22 can also be referred to as a protective arrangement. The terms "arrangement" and "protective arrangement" are therefore interchangeable. The arrangement 22 comprises one of the structural components 8 to 11, in this case the third structural component 10. However, the arrangement 22 can also comprise the first structural component 8, the second structural component 9, and / or the fourth structural component 11. However, it is assumed below that the arrangement 22 comprises the third structural component 10, which is a floor of the vehicle cell 2.

[0077] A first support element 23 can be attached to the third structural component 10. The first support element 23 can be a plate, in particular a steel plate, a sheet metal, or the like. The first support element 23 can be firmly connected to the third structural component 10 by means of a weld seam 24. The first support element 23 is welded to the inner side 16 of the third structural component 10. The first support element 23 comprises a front side 25 and a rear side 26 facing away from the front side 25. The first support element 23 lies parallel to a plane spanned by the x-direction x and the y-direction y. The first support element 23 is oriented perpendicular to the third structural component 10.

[0078] The arrangement 22 comprises an additional component 27 as mentioned above. The additional component 27 can also be referred to as an additional component. The terms "additional component" and "additional component" are therefore interchangeable. The additional component 27 can be a bulkhead, a partition, a shelf structure, or the like. Furthermore, the additional component 27 can also be a removable armor plate attached to the outside of the vehicle cell 2. In the present case, the additional component 27 is a shelf structure suitable for accommodating equipment 28.

[0079] In the present case, the additional component 27 is plate-shaped and comprises an upper side 29, which faces away from the inner side 16 of the third structural component 10, and a lower side 30, which faces the inner side 16. The piece of equipment 28 is placed on the upper side 29. The additional component 27 is spaced apart from the third structural component 10 and arranged parallel to it.

[0080] The additional component 27 comprises a second support element 31, which is plate-shaped. The second support element 31 can be a steel plate or a sheet metal. The second support element 31 is firmly connected to the additional component 27, in particular to the underside 30 of the additional component 27, by means of a weld seam 32. The second support element 31 comprises a front side 33, which faces the front side 25 of the first support element 23, and a rear side 34 facing away from the front side 33. The second support element 31 lies parallel to a plane spanned by the x-direction x and the y-direction y. The support elements 23, 31 are thus positioned parallel to one another. The second support element 31 is oriented perpendicular to the additional component 27.

[0081] The first support element 23 and the second support element 31 are connected to one another by means of a detachable connecting and decoupling device 35. Thus, the third structural component 10 and the additional component 27 are indirectly coupled or connected to one another by means of the support elements 23, 31 and the connecting and decoupling device 35.

[0082] The connecting and decoupling device 35 comprises a first connecting and decoupling element 36, which is assigned to the third structural component 10 or the first support element 23, and a second connecting and decoupling element 37, which is assigned to the additional component 27 or the second support element 31. The connecting and decoupling elements 36, 37 can also be referred to as connecting and separating elements. The connecting and decoupling device 35 acts as a predetermined breaking point between the support elements 23, 31. The terms "connecting and decoupling device" and "predetermined breaking point" can therefore be interchanged as desired. Furthermore, the connecting and decoupling device 35 can also be referred to as a connecting and separating device.

[0083] In the simplest case, the connecting and decoupling device 35 is an adhesive bond, with the connecting and decoupling elements 36, 37 being part of this bond. In this case, the support elements 23, 31 are firmly bonded to one another using the connecting and decoupling device 35. In firmly bonded connections, the connecting partners are held together by atomic or molecular forces. Firmly bonded connections are non-detachable connections that can only be separated by destroying the connecting means and / or the connecting partners.

[0084] To separate or decouple the support elements 23, 31, the connecting and decoupling device 35 can be destroyed accordingly, wherein a first part of the connecting and decoupling device 35 remains as a first connecting and decoupling element 36 on the first support element 23 and a second part of the connecting and decoupling device 35 remains as a second connecting and decoupling element 37 on the second support element 31.

[0085] A positive connection can also be provided between the first connecting and decoupling element 36 and the second connecting and decoupling element 37. A positive connection is created by the interlocking or engaging of at least two connecting partners, in this case the two connecting and decoupling elements 36, 37. In this case, the connecting and decoupling device 35 can be a hook-and-loop fastener or a hook-and-loop connection, as explained in more detail below. The first connecting and decoupling element 36 can engage with engagement sections 38 (Fig. 5) into corresponding mating engagement sections 39 of the second connecting and decoupling element 37.

[0086] The connection between the first connecting and decoupling element 36 and the second connecting and decoupling element 37 can also be force-locked. A force-locked connection requires a normal force on the surfaces to be connected. Force-locked connections can be realized by frictional engagement. The mutual displacement of the surfaces is prevented as long as a counterforce caused by static friction is not exceeded. A force-locked connection can also be a magnetic force-locked connection. In this case, one of the connecting and decoupling elements 36, 37 can have magnetic properties. For example, one of the connecting and decoupling elements 36, 37 can be a permanent magnet. Both connecting and decoupling elements 36, 37 can also be magnetic.

[0087] Fig. 6 shows a schematic view of an embodiment of a connecting and decoupling device 35 as mentioned above.

[0088] In this embodiment, the connecting and decoupling device 35 is designed as a hook-and-loop fastener or a Velcro connection. The first connecting and decoupling element 36 has a band-shaped or plate-shaped base section 40 that is firmly connected to the first support element 23. For example, the base section 40 has an adhesive layer so that the base section 40 can be glued to the first support element 23. However, the base section 40 can also be riveted or screwed to the first support element 23. The first connecting and decoupling element 36 can be made of a plastic material. The first connecting and decoupling element

[0089] However, 36 can also be made of a metallic material. Composite materials can also be used for the first connecting and decoupling element 36.

[0090] A plurality of engagement sections 38, as previously mentioned, extend from the base section 40. The engagement sections 38 are barb-shaped or hook-shaped. The engagement sections 38 can therefore also be referred to as hook sections. Thus, the terms "engagement section" and "hook section" can be interchanged. However, the geometry of the engagement sections 38 is fundamentally arbitrary. The engagement sections 38 are preferably arranged evenly distributed on the base section 40. The base section 40 comprises a front side 41, from which the engagement sections 38 extend, and a rear side 42 facing away from the front side 41, which is connected, for example, glued, to the first carrier element 23.

[0091] The second connecting and decoupling element 37 also has a band-shaped or plate-shaped base section 43, which, however, is firmly connected to the second carrier element 31. For example, the base section 43 has an adhesive layer, so that the base section 43 can be glued to the second carrier element 31. However, the base section 43 can also be riveted or screwed to the second carrier element 31.

[0092] The second connecting and decoupling element 37 can be made of a plastic material. The second connecting and decoupling element

[0093] However, the second connecting and decoupling element 37 can also be made of a metallic material. Composite materials can also be used for the second connecting and decoupling element 37. A plurality of counter-engagement sections 39, as previously mentioned, extend from the base section 43. The counter-engagement sections 39 are loop-shaped. The counter-engagement sections 39 can therefore also be referred to as loop sections. Thus, the terms "counter-engagement section" and "loop section" are interchangeable. However, the geometry of the counter-engagement sections 39 is fundamentally arbitrary.

[0094] The counter-engagement sections 39 are preferably arranged uniformly distributed on the base section 43. The base section 43 comprises a front side 44, from which the counter-engagement sections 39 extend, and a rear side 45 facing away from the front side 44, which is connected, for example, glued, to the second carrier element 31.

[0095] To connect the connecting and decoupling elements 36, 37, they are pressed together with a respective assembly force F1, F2, so that the engagement sections 38 engage positively with the counter-engagement sections 39. The connecting and decoupling elements 36, 37 are then positively connected to one another. The positive connection can preferably be released and re-established as often as desired. The assembly forces F1, F2 are oriented along and opposite to the z-direction z. In particular, the assembly forces F1, F2 are oriented perpendicular to the base sections 40, 43.

[0096] The functionality of the connecting and decoupling device 35 is explained below with reference to Figs. 3 to 6. When the vehicle 1 is detonated as mentioned above, the pressure wave 21 of the explosive device 20 moves the third structural component 10 from an undeformed or undeformed state Z1 shown in Fig. 3 to a deformed or deformed state Z2 shown in Fig. 4. This ballistic deformation of the third structural component 10 can be elastic and / or plastic. This means that the deformation can be at least partially reversible and at least partially irreversible. However, the deformation of the third structural component 10 can also be purely plastic.

[0097] When the third structural component 10 is moved from the undeformed state Z1 to the deformed state Z2, the third structural component 10 deforms into the interior space 3, causing the first support element 23 to move upwards along the y-direction y. Since the additional component 27 initially does not move due to its mass inertia, two oppositely oriented shear forces F10, F20 act on the connecting and decoupling device 35. A first shear force F10 acting on the first connecting and decoupling element 36 is oriented along the y-direction y, and a second shear force F20 acting on the second connecting and decoupling element 37 is oriented opposite to the y-direction y.

[0098] Due to this relative movement of the support elements 23, 31 to one another, no buckling loads are applied to the support elements 23, 31, thus preventing damage to them. During normal operation, i.e., as long as no wringing is performed and no significant deformation of the respective structural component 8 to 11 is expected, this type of connection also provides vibrational decoupling of the additional component 27 from the respective structural component 8 to 11.

[0099] This decoupling allows for small relative movements between the two support elements 23, 31, which do not lead to a break in the connection. In this case, the connecting and decoupling device 35 acts as a damper or damping element, which eliminates the need for additional decoupled suspensions of the additional component 27.

[0100] The shear forces F10, F20 cause the connecting and decoupling elements 36, 37 to be separated from each other, so that the additional component 27 does not follow the movement of the third structural component 10 into the interior 3. Accordingly, the piece of equipment 28 is also not accelerated in an undesirable manner, which means that it cannot act as a projectile on a crew located in the interior 3. Injuries to the crew can thus be reliably prevented.

[0101] If the connecting and decoupling device 35 is a hook-and-loop connection or a hook-and-loop fastener, as shown in Fig. 6, the engagement sections 38 and the counter-engagement sections 39 are disengaged from the positive engagement during the wringing process. However, after the wringing process, the connecting and decoupling elements 36, 37 can be reconnected to one another.

[0102] The shear forces F10, F20 are achieved by the relative movement between the support elements 23, 31. If these shear forces F10, F20 are sufficiently large, the connection between the connecting and decoupling elements 36, 37 is severed by shearing. If the connecting and decoupling device 35 is a hook-and-loop connection, the respective triggering shear force F10, F20 of the connecting and decoupling device 35 can be adjusted as desired by selecting a suitable hook-and-loop connection.

[0103] In this case, "destruction" of the connection between the connecting and decoupling elements 36, 37 is limited to the Velcro connection designed as a connecting and decoupling device 35, which makes it possible to re-establish a connection with the existing support elements 23, 31, provided the support elements 23, 31 are not excessively damaged. In particular, the second support element 31 is a component to be protected, which only has to absorb the necessary second shear force F20 by breaking the connection. The second shear force F20 should be so small that damage to the second support element 31 and thus to the additional component 27 is excluded.

[0104] The arrangement 22 thus makes it possible to mount, in particular suspend, any additional components 27, such as partition walls, brackets, shelves, or the like, in a space- and weight-efficient manner, decoupled from surfaces endangered by the pressure wave 21. A predetermined predetermined breaking point in the form of the connecting and decoupling device 35 enables separation of the additional component 27 from the respective structural component 8 to 11, which prevents the introduction of energy into the additional component 27 in the event of the penetrating pressure wave 21.

[0105] The connecting and decoupling device 35 is mounted in safety-critical areas and thus prevents the energy of the pressure wave 21 from being transmitted to the additional component 27 and the structures connected to it. The two independent connecting and decoupling elements 36, 37 of the connecting and decoupling device 35 are preferably physically connected to each other in the manner of a hook-and-loop fastener.

[0106] In the event that the connecting and decoupling device 35 is a hook-and-loop fastener or a Velcro fastener, the connecting and decoupling device 35 can be selected to meet the respective requirements and thus also assume vibration-damping properties. In the event of a ballistic deformation of the respective structural component 8 to 11, a bulging of the respective structural component 8 to 11 resulting from the deformation separates the connecting and decoupling device 35 by means of the shear forces F10, F20, whereby the bulging of the structural component 8 to 11 is not passed on to the decoupled additional component 27. With the aid of the arrangement 22, it is thus possible for any additional components 27 to be suspended in safety-critical areas without posing a danger to crew members located in the vehicle cell 2.Large and heavy structures for suspending such additional components 27 from non-critical areas of the vehicle cell 2, such as the roof in the form of the fourth structural component 11, can advantageously be avoided, thereby saving both weight and installation space. However, it cannot be ruled out that an additional component 27 with such a connecting and decoupling device 35 is also connected to the fourth structural component 11.

[0107] In addition, with an appropriate design of the connecting and decoupling device 35, for example in the form of a hook-and-loop connection, it is possible to achieve vibration damping between the respective structural component 8 to 11 and the additional component 27, thereby making additional decoupling obsolete. A further advantage is that the connection between the respective structural component 8 to 11 and the additional component 27 can be created very cost-effectively and without additional components. In the event that the connecting and decoupling device 35 is a hook-and-loop connection, this is glued to the planar front sides 25, 33 of the support elements 23, 31 to be connected. This eliminates the need for complex welding preparation, and the tolerances can be somewhat coarser than with comparable welded structures.

[0108] If the connecting and decoupling device 35 is an adhesive bond or an adhesive point, the function of the predetermined breaking point can be achieved by a suitable selection of the adhesive and a suitable adhesive thickness. For example, an elastic adhesive bond, such as using silicone or sealing tape, can be implemented. Depending on the selection of this adhesive bond, a separation of the additional component 27 from the respective structural component 8 to 11 can also be achieved by the applied shear forces F10, F20.

[0109] Although the present invention has been described using exemplary embodiments, it can be modified in many ways.
