Definitions
- the present invention relates to a vehicle cell for a protected vehicle and a protected vehicle having such a vehicle cell.
- a protected vehicle comprises a vehicle cell protected against bullets.
- additional components such as bulkheads, partitions, shelving structures or the like
- additional components usually have a high level of rigidity. Due to their rigidity, these additional components can react by buckling when large forces are introduced, which can lead, for example, to items of equipment mounted in or on the respective additional component being greatly accelerated. This in turn can cause these pieces of equipment to accelerate so much that they act like projectiles within the vehicle cell. In the event of a blast on the protected vehicle, it must therefore be ensured that no energy and thus no acceleration are introduced into the additional components.
- additional components can be hung decoupled from a floor of the vehicle cell.
- Additional components in the form of bulkheads or partitions can be curved. It is also possible to split them up and weld them in an overlapping manner, so that buckling or deformation takes place in a controllable area.
- the aforementioned measures can result in a comparatively complex and heavy construction being required.
- the previously mentioned solutions do not offer any conclusive security to the effect that energy is not introduced into the additional components as a result of the connection of the additional components to the vehicle cell. Curved bulkheads or partitions also require more space on, which can also complicate the construction of adjacent components in the immediate vicinity. This needs to be improved.
- the vehicle cell comprises an arrangement that has a structural component, an additional component that is placed within the vehicle cell, and a connecting and decoupling device, with the aid of which the additional component is connected to the structural component, the connecting and decoupling device being set up to Additional component to be mechanically decoupled from the structural component in the event of a deformation of the structural component resulting from a wringing of the structural component, and wherein the connecting and decoupling device is a Velcro fastener.
- connecting and decoupling device is suitable for mechanically decoupling the additional component from the structural component when it is subjected to stress can reliably prevent forces and accelerations resulting from the stress from being transmitted from the deformed structural component to the additional component. Items of equipment stored on or in the additional component cannot therefore act as projectiles.
- the arrangement can also be referred to as a protective arrangement. Accordingly, the terms “arrangement” and “protective arrangement” can be arbitrarily interchanged with one another.
- a "protected” vehicle is understood to mean a vehicle that is protected against fire, booby traps, improvised explosive devices (IED), mines, any explosive devices or the like is protected. For this purpose, the vehicle can be armored.

- the arrangement can thus be part of the vehicle cell.
- the driving cell itself can function as a structural component.
- the vehicle cell itself can be the structural component.
- the vehicle cell preferably encloses an interior space in which crew members or a vehicle crew can stay.
- the additional component is placed within this interior or within the vehicle cell. However, this is not mandatory.

- the deformation is elastic and/or plastic. This means that the deformation can at least partially recover.
- the ancillary component may be a shelf structure, bulkhead, bulkhead, armor or the like.
- the additional component can also be a floor that can be placed inside the vehicle cell.
- the additional part can also be referred to as an additional component.
- the additional component can be set up to accommodate items of equipment.
- the additional component is preferably a shelf or a shelf structure.
- the connecting and decoupling device connects the additional component to the structural component.

- the Velcro connection is in particular opened or released when the structural component is subjected to stress or when the structural component is deformed.
- a non-positive connection requires a normal force on the surfaces to be connected. Force-locking connections can be realized by frictional locking. Mutual displacement of the surfaces to be connected is prevented as long as a counterforce caused by static friction is not exceeded.
- a non-positive connection can be present, for example, as a magnetic non-positive connection. In this case, the connecting and decoupling device has magnetic properties at least in sections.

Accordingly, the terms “connecting and decoupling device” and “predetermined breaking point” can be interchanged as desired.
- the mechanical decoupling of the additional component from the structural component takes place in particular in that the cohesive, form-fitting and/or non-positive connection produced by the connecting and decoupling device is automatically released when the structural component is subjected to stress.
- the additional component of the connecting and decoupling device is positively connected to the structural component.
- a positive connection can be undone and restored any number of times. This means in particular that after the structural component has been subjected to blasting, the additional component can be connected to the structural component again. Both the detachment and the connection can be carried out in particular without tools. A form-fitting connection is thus produced between the additional component and the structural component with the aid of the connecting and decoupling device.

- connection and decoupling device 35 The functionality of the connection and decoupling device 35 is explained below with reference to FIGS.
- the pressure wave 21 of the explosive charge 20 moves the third structural component 10 from an undeformed or undeformed state ZI shown in FIG. 3 into a deformed or deformed state Z2 shown in FIG.
- This ballistic deformation of the third structural component 10 can be elastic and/or plastic. This means that the deformation is at least partially reversible and at least partially irreversible. can be flexible. However, the deformation of the third structural component 10 can also be purely plastic.
- the third structural component 10 When the third structural component 10 is brought from the undeformed state ZI into the deformed state Z2, the third structural component 10 deforms into the interior space 3, as a result of which the first carrier element 23 moves upwards viewed along the y-direction y. Since the additional component 27 initially does not move due to its mass inertia, two oppositely oriented shearing forces F10, F20 act on the connecting and decoupling device 35. A first shearing force F10 acting on the first connecting and decoupling element 36 is oriented along the y-direction y and a second shearing force F20 acting on the second connecting and decoupling element 37 is oriented counter to the y-direction y.
- This movement of the support elements 23, 31 relative to one another means that no buckling loads are applied to the support elements 23, 31, which means that damage to the same is ruled out.
- this type of connection also results in a vibration-related decoupling of the additional component 27 from the respective structural component 8 to 11.
- the connecting and decoupling device 35 functions as a damper or damping element, which makes the need for further decoupled suspensions of the additional component 27 obsolete.
- the shear forces F10, F20 cause the connecting and decoupling elements 36, 37 to be separated from one another, so that the additional component 27 of the Movement of the third structural component 10 into the interior 3 does not follow. Accordingly, the item of equipment 28 is also not accelerated in an undesired manner, which means that it cannot act as a projectile on a crew located in the interior 3 either. Injuries to the crew can thus be reliably prevented.
- connection and decoupling device 35 is a Velcro connection or a Velcro fastener, as is shown in FIG. 6, the engagement sections 38 and the counter-engagement sections 39 come out of positive engagement when the force is applied. However, after the wringing, the connecting and decoupling elements 36, 37 can be connected to one another again.
- the shearing forces F10, F20 are achieved by the relative movement between the carrier elements 23, 31. If these shearing forces F10, F20 are sufficiently large, the connection between the connecting and decoupling elements 36, 37 is severed by shearing. In the event that the connecting and decoupling device 35 is a Velcro connection, a respective triggering shearing force F10, F20 of the connecting and decoupling device 35 can be set as desired by selecting a suitable Velcro connection.
- connection between the connecting and decoupling elements 36, 37 is limited to the Velcro connection designed as the connecting and decoupling device 35, which makes it possible to reconnect to the existing carrier elements 23, 31 if the carrier elements 23 , 31 are not too badly damaged.
- the second carrier element 31 is a component to be protected, which only has to absorb the necessary second shearing force F20 due to the separation of the connection.
- the second shear force F20 should be as small be that damage to the second carrier element 31 and thus to the additional component 27 is ruled out.
- connection and decoupling device 35 enables the additional component 27 to be separated 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.
- connection and decoupling device 35 is installed in safety-critical areas and thus prevents the energy of the pressure wave 21 from being introduced into the additional component 27 and 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 one another in the manner of a Velcro strip or Velcro fastener.
- the connecting and decoupling device 35 is a Velcro strip or a Velcro fastener
- the connecting and decoupling device 35 can be selected to meet the respective requirements and can thus also assume vibration-damping properties.
- 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, as a result of which the bulging of the structural component 8 to 11 does not connect to the decoupled Additional component 27 is forwarded.
- the arrangement 22 it is thus possible for any additional components 27 to be hung up in safety-critical areas without there being a risk to crew members staying in the vehicle cell 2 .
- connection and decoupling device 35 for example in the form of a Velcro connection
- connection and decoupling device 35 to achieve vibration damping between the respective structural component 8 to 11 and the additional component 27, which means that additional decoupling devices become obsolete.
- connection between the respective structural component 8 to 11 and the additional component 27 can be produced very inexpensively and without additional components.
- the connecting and decoupling device 35 is a Velcro bandage, this is glued to the planar front sides 25, 33 of the carrier elements 23, 31 to be connected. There is therefore no complex welding preparation to be carried out and the tolerances can be somewhat coarser than with comparable welded structures.
- the function of the predetermined breaking point can be achieved by a suitable selection of the adhesive and a suitable adhesive thickness.
- an elastic adhesive connection such as with the help of silicone or sealing tapes, can be implemented.
- this bonded joint can also be a separation of the additional component 27 from the respective structural component 8 to 11 are generated by the applied shearing forces F10, F20.
