    fired projectiles or fragmented elements. At least in connection with ballistic effects, armored structures also provide effective protection against detonation waves.
    To reach the interior of a motor vehicle or building that is armored / armored in this way, it must have at least one opening that can be closed. The door, hatch or lid required for this is separate from the rest of the construction with a gap that mostly goes around to move this / this if necessary so that it / it is thereby opened. Due to the interruption in the armored structure required, such a gap constitutes an almost inevitable weakening of the protective function. Due to the structural gap in the structure, harmful effects can not be prevented, which means that projectiles or at least splinters can enter the area to be protected almost unhindered.
    To compensate for the weakening of the armored structure at the gap, suitable splinter protection devices are known at the current level of technical development. The measures which in this context are limited to purely constructive embodiments comprise a shielding element which at least partially bridges the gap between the components. Via the shielding against accelerated bodies, a suitable sealing effect between the adjacent components must also be achieved. The design of suitable sealing elements depends on the current requirements for tightness. These requirements range from sealing against liquid media all the way to, for example, shielding against ABC weapons. GB 2 391 591 A shows a splinter protection device for shielding a gap which is located between a first component and a second component of an armored structure. One of the components then constitutes a closing device for an opening so that it can be moved in relation to the surrounding components. The shatter protection device comprises at least one shielding element which is at least indirectly attached to the first component. To bridge the gap, the shielding element is arranged at the gap. Thanks to this, a body that passes the gap is caught or at least braked sharply.
    By arranging such a shielding element, effective protection of the armored structure at the gap is made possible. However, in the case of an unfavorable constellation of the width of the gap, the distance of the gap and the covering width of the shielding element and the angle of the path of an accelerated body, it cannot be completely ruled out that the body penetrates.
    The armored structure, which is at least partly composed of protective steel, is connected to the splinter protection device via welded joints. When this is done, the positive properties of the protective steel achieved through a previous heat treatment can be impaired due to the local welding heat.
    Thanks to the connection between the components that form the protective cover and the elements of the splitter protection device, composite cross-sections are also generated. In particular, through their shear-resistant connection via welds, local cross-sectional jumps are generated in this way, which leads to a corresponding stiffness jump thanks to the moment of resistance achieved in this way.
    The areas of uneven stiffness consequently exhibit deformation properties that deviate from each other. Particularly in the transition areas between the different rigidities, high shear stresses are sometimes generated by this, which can, for example, lead to the protective cover being torn up locally in a construction which is subjected to stress by a shock wave.
    DE 102006 052 609 A1 mentions a under-protected vehicle whose chassis is reinforced with welded joints with stiffening reinforcements. To reduce the stiffness jumps that occur at the composite cross-sections, the idea is that the chassis should not be welded directly to a stiffening reinforcement, but that a shear protection element should be arranged on the respective stiffening reinforcement.
    The shear protection element then extends parallel to the extension of the chassis and is welded to it in the edge area. In this position, the shear protection element is kept at a distance from the chassis with an air gap.
    The respective reinforcing ribs are arranged via suitable welding joints first on the shear protection element itself. These welded joints have a distance of at least 20 mm from the welded joints that connect the chassis to the shear protection element.
    The present invention has for its object to improve the efficiency of a splinter protection device of the type mentioned at the beginning.
    The solution of this task according to the invention consists of a shatter protection device according to the features of claim 1. In addition, the task is solved with a shatter protection device according to the features of claim 8. A further solution of the task according to the invention is found in a shatter protection device according to claim 12. 24 each shows an additional solution to the task. Accordingly, a splitter protection device is provided for shielding a gap located between a first component and a second component in an armored structure where one of the components can be moved relative to the other. The armored structure may in particular be an armored motor vehicle. The splinter protection device comprises at least one shielding element of protective steel which is attached to the first component with a connecting element. The shielding element is then arranged at the gap so that the shielding element bridges the gap.
    In accordance with the invention, the connecting element is attached to the first component indirectly via an intermediate element. The particular advantage of this is the reduction of the stiffness jump that otherwise occurs. In a direct arrangement of the connecting element on the first component, in particular via a welded joint, a shear-resistant connection would be arranged between them. This connection results in the first component and the connecting element resulting in a composite component which sometimes has a significantly higher moment of resistance compared to the areas surrounding the first component. Due to the varying deformation properties of the areas surrounding the first component which this gives rise to compared with the composite cross-section, shear stresses are generated at a corresponding height in the transition areas at a bending load.
    Thanks to the use of the intermediate element, no direct connection is generated between the connecting element and the first component. The respective resistance moments are added to a maximum, in particular due to the missing shear connection between the connecting element and the first component, so that the stiffness gap is considerably reduced compared with a direct welding of the connecting element on the first component. As a result, significantly lower shear stresses occur in the first component at a bending load which has been triggered, for example, by the shock waves from a detonation so that it stops functioning only at significantly higher loads.
    The intermediate element is advantageously attached to the first component, at least in part, via a first weld so that the first weld is arranged in an edge region running along the space of the first component. In other words, the interconnection of the intermediate element and the first component takes place in its edge region in the immediate vicinity of the gap. The possible weakening of the protective steel due to the application of welding heat to its edge area is thereby reduced in an advantageous manner.
    A consequence of this is that the positive properties in the areas surrounding the first component are maintained.
    The weakening of the first component in the immediate edge area towards the gap can be taken into account without further ado since an accelerated body which has penetrated the weakened account area is caught by the shielding element.
    In addition, the deterioration of the first component, possibly also in appearance, is concentrated only to its edge area due to a skew caused by the welding heat. Thanks to this, at least most of the surface of the first component is spared from a possible skew.
    In order to reduce the negative effects of a composite cross-section on the connecting element as much as possible, the invention requires that the connecting element is arranged at a distance from the edge which constitutes the boundary of the first component to the gap. The aim is to remove the connecting element from the weld joint which locks the intermediate element on the first component. The longer the distance between the connecting element and the edge of the first component, the less the height of the connecting element extending perpendicular to the plane of the first component affects the rigidity of this area.
    The width of the intermediate element can run constantly along the edge of the first component. In principle, the width of the first intermediate element can also vary. Preferably, the distance between the connecting element and the edge of the first component should be between 50% and 80% of the width of the intermediate element. The distance can in particular amount to between 60% and 70% of the width of the intermediate element.
    In principle, the distance between the connecting element and the first component can then be appropriate. As an alternative to this, the distance between the weld joint connecting the connecting element and the intermediate element and the edge of the first component can also be appropriate. This applies in particular if this weld is arranged on a side of the connecting element which is turned away from the edge.
    Preferably, the thickness of the intermediate element should be between 20% and 80% of the thickness of the first component. If the first and second components are different thicknesses, the intermediate element can also amount to between 20% and 80% of the thickness of the second component. The thickness of the intermediate element can in particular also amount to between 20% and 50% of the thickness of the first component and / or the thickness of the second component. Due to the smaller thickness of the intermediate element compared to the thickness of the first and second components, its rigidity is less.
    Due to the smaller thickness of the intermediate element, a possible deformation of the first component is transmitted to the intermediate element via the welding joint which connects the intermediate element to the first component, but is not passed on to the connecting element which is connected to the intermediate element to the same extent. In other words, the small thickness of the intermediate member allows dents between its attachment to the first component and the connecting member.
    Preferably, the shielding element should have a projection. This protrusion should then extend in the direction of the other component. The protrusion leads to the space between the first component and the shielding element being limited on one side of the connecting element also, at least in part, being limited on the side opposite the connecting element. Due to the height of the projection which extends away from the shielding element and to the second component, the necessary frame of the space can be designed as required. The protrusion leads to an object that possibly arrives at the space at a flat angle through the gap being prevented resp. captured by the protrusion. In this way, an element which penetrates through the gap and bounces on the connecting element can also be prevented resp. captured by the protrusion.
    Within the scope of the invention, the projection can be arranged as a separate element on the shielding element. In an alternative embodiment, the projection can be constituted by a part of the shielding element in a piece of uniform material.
    The arrangement of the projection as a separate element has the advantage that in particular the shielding element can be made of an element with standard dimensions and / or shapes. In other words, the sometimes costly redesign to form a protrusion can be eliminated. Compared with this, for example, a round curved deformation of the shielding element for shaping the projection has appearance and haptic advantages since the shielding element has no protruding edges towards the inner space to be protected.
    In a further aspect, a splitter protection device is shown for shielding a gap which is placed between a first component and a second component of an armored structure. This can in particular be an armored motor vehicle. One of the components is, for example, a door, a door or a window that can be opened so that one of the components can be moved relative to the other. The splinter protection device has at least one shielding element which is attached to the first component via a first weld joint. The shielding element is then arranged in the area by the gap so that it bridges the gap. In accordance with the invention, the first weld is arranged along an edge region of the first component running along the gap. The possible weakening of the protective steel due to the application of welding heat to its edge area is thereby reduced in an advantageous manner. A consequence of this is that the positive properties in the areas surrounding the first component are maintained.
    The weakening of the first component in the immediate edge area towards the gap can be taken into account without further ado since an accelerated body which has penetrated the weakened account area is caught by the shielding element.
    In addition, the deterioration of the first component, possibly also in appearance, is concentrated only to its edge area due to a skew caused by the welding heat. Thanks to this, at least most of the surface of the first component is spared from a possible skew.
    The shielding element has a curved cross section. The shielding element has a projection located on its free edge which extends in the direction of the second component. The protrusion leads to the space between the first component and the shielding element being limited on one side of the connecting element also, at least in part, being limited on the side opposite the connecting element. Due to the height of the projection which extends away from the shielding element and to the second component, the necessary frame of the space can be designed as required.
    The protrusion leads to an object that possibly arrives at the space at a flat angle through the gap being prevented resp. captured by the protrusion. In this way, an element which penetrates through the gap and bounces on the connecting element can also be prevented resp. captured by the protrusion.
    Within the scope of the invention, the projection can be arranged as a separate element on the shielding element. In an alternative embodiment, the projection can be formed by a part of the shielding element in a piece of uniform material.
    The arrangement of the projection as a separate element has the advantage that in particular the shielding element can be made of an element with standard dimensions and / or shapes. In other words, the sometimes costly redesign to form a protrusion can be eliminated. Compared with this, for example, a round curved deformation of the shielding element for shaping the projection has appearance and haptic advantages since the shielding element has no protruding edges towards the inner space to be protected.
    The shielding element runs parallel to the area of the first component within which the shielding element is attached to the first component at the end opposite the free edge. Preferably, the shielding element should be attached to the end opposite the protrusion via a welding spot on the first component. In particular, due to the parallel course of the shielding element in this area opposite the first component, no significant cross-sectional jump is generated in the form of a composite component. In particular, the square incoming height of the components doubled in this range which is included in the calculation of the resistance moment is reduced to their respective thickness. Compared with a process which extends vertically towards the plane of the first component, the parallel device consequently leads only to a small stiffness jump which in addition only relates to the part of the elements which are connected to each other and which is in the immediate vicinity of the welded joint.
    Depending on the requirements, the shielding element may have a bend which is directed towards the projection at the end opposite the projection. Preferably, the bend should then be designed so that the shielding element has no substrate surface in the contact area of the first component. Thanks to the design of the shielding element in this way rounded in the contact area towards the first component by the bending, this can be used more flexibly. This abuts the contact between the shielding element and the first component which has been reduced to a minimum. In particular, equal or oppositely curved areas of the first component can in this way be connected to the shielding element without problems. Due to this, a sometimes necessary adjustment of the area of the shielding element intended for the contact with the first component is omitted.
    A further aspect of the invention relates to a splitter protection device for shielding a gap which is placed between a first component and a second component in an armored structure. An armored construction can in particular be an armored motor vehicle where one of the components can be moved compared to the other. The shatter protection device then comprises a shielding element which is attached to the first component.
    The shielding element is then arranged at the gap so that it bridges it. According to the invention, the first component has a projection on its edge area which runs along the gap. The shielding element is then attached to the projection, at least in part.
    The protrusion may, for example, be a bend of the first component in the edge area which runs along the gap. The inflection can be generated directly for the first component in the design process.
    Alternatively, the bending can be done in connection with the shaping process for the first component within a separate bending process. In particular with a large wall thickness of the first component, the protrusion can also be generated by a reduction of the thickness of the first component in the edge area.
    The shielding element has been arranged harmoniously in the geometry of the first component through the projection. In the visible area in particular, it is possible thanks to this to realize an almost jointless transition from an inner or outer surface of the first component to the shielding element. Thanks to the oriented positions of the shielding element over the projection opposite the first component, it is also possible to set as small a cross-sectional projection as possible by the shielding element being aligned at as acute an angle as possible to the parallel course of the first component.
    In principle, the shielding element and the first component are material-tightly connected to each other. In addition to a welded joint, the invention provides an adhesive joint in an advantageous manner. The advantage that the gluing provides is that the elements to be connected to each other, in particular the first component, are not deformed by application of welding heat. In addition, the positive properties of the material used generated by a heat treatment which would otherwise be lost or at least partially reduced are maintained.
    A further aspect of the invention relates to a splitter protection device for shielding a gap which is placed between a first component and a second component in an armored structure so that one of the components can be moved relative to the other. The armored structure may in particular be an armored motor vehicle. The splinter protection device comprises at least one shielding element which is attached to the first component via a connecting element. The shielding element is then arranged at the gap so that the shielding element bridges the gap. In accordance with the invention, the shielding element has a curved cross section with a projection located on its first free edge. On the second free edge of the shielding element which lies opposite the first free edge, a directional bend is arranged.
    The projection and the bend should preferably be oriented towards the components, which means that they grip the gap together with the shielding element.
    The connecting element is then arranged between the projection and the bend. In addition, in the case of a connecting element arranged only in sections, bodies are also caught in the gap at an acute angle to the plane of the components.
    In other words, not only the area immediately behind the column but also the side areas adjacent to it are secured.
    Within the scope of the invention, the projection can in principle also be arranged as a separate element on the shielding element. The arrangement of the projection as a separate element has the advantage that in particular the shielding element can be made of an element with standard dimensions and / or shapes. In other words, the sometimes costly redesign to form a protrusion can be eliminated. Compared with this, for example, a round curved deformation of the shielding element for shaping the projection has appearance and haptic advantages since the shielding element, for example, has no protruding edges towards the inner space to be protected. The projection then extends a part of the shielding element in a piece of uniform material.
    Preferably, the shielding element should have through openings. The openings must be arranged in the area of the connecting element. The shielding element can be connected to the connecting element through the easily accessible openings. In addition to the use of rod-shaped connecting means, the shielding element should preferably be welded to the connecting element through the openings.
    An alternative design stipulates that the connecting element is at least partially arranged through the openings in the shielding element. In this way, the alignment of the shielding element towards the connecting element can be fixed already via the design of those of the areas of the connecting element which correspond to each other and the openings, which simplifies the welding overall. A press fit can then, for example, be made in certain areas so that the shielding element can be fixed to the connecting element even before welding.
    The connecting element can at least partially be attached to the first component via a welded joint. The welded joint may be arranged on a side of the connecting element facing away from the gap. In principle, the welded joint can also be arranged on a side of the connecting element which faces the gap. The advantage of the arrangement of the welded joint on one side of the connecting element facing the gap consists above all in an improvement in appearance. In this way, the appearance of the shielding element and the connecting element are not clouded by a possible welded joint when one of the components is moved.
    The advantage of a welded joint arranged on the side of the connecting element facing the gap is that it is predominantly subjected to stresses by tensile forces under load. This is because during loading of the shielding element which moves away from the gap, a tilting of the connecting element arises which then rests on the first component. On the other hand, a side of the connecting element which is turned away from the gap is tensile stressed more due to the smaller lever arm because the connecting element cannot be supported against the first component but is tipped away from it.
    In addition, it is arranged so that the shielding element is at least partially attached to the connecting element via a welded joint. The welded joint can in particular be arranged on the side of the connecting element which is turned away from the gap and / or the shielding element. The advantage in the arrangement of the welding device on the side of the connecting element which is turned away from the gap and / or the shielding element is above all an improved appearance.
    In this way, for example, panel elements which are mounted from the inner space of the armored structure and extend to the connecting element via the shielding element, which means that the welded joint is covered in appearance in an advantageous manner by these connecting elements.
    A principal idea of the invention advantageously assumes that the edges of the two components which lie opposite each other at the gap are parallel to each other at least in part. In addition, the areas of the edges which are parallel to the outer surface or inner surface of the first component may have an angle other than 90 °. By tilting the edges delimiting the gap, in particular, the flight path of a body in the normal area directed towards the components is interrupted by the areas of the edges extending into the gap. Preferably, the areas of the inclined gap which are parallel to each other should have a mutual overlap. This leads to a body's normal flight path directed towards the components encountering several materials in succession, which can lead to the body being stopped successfully.
    The edges which limit the inclination of the gap should preferably be designed in such a way that both components have been manufactured from a continuous element in a single working step. As a starting point for this, for example, a continuous armor or steel protection plate can function from which the two components are separated. The separation can be performed, for example, by a water jet cutting process or by using a 3D laser. Its cutting direction must then be inclined in the angular position that is suitable so that the edges of the two components that lie opposite each other have the desired inclination with a single cut.
    A further principal idea of the invention is that the shielding element has a splinter protection fabric in an area facing the gap.
    The splinter protection fabric can, for example, be connected to the shielding element via an epoxy resin. The splinter protection fabric can be, for example, aramid fibers. The shatterproof fabric may also contain at least aramid fibers. The advantage lies in the very high strength, in particular the high impact strength of the aramid fibers, the positive properties of which in this context are combined with the steel material used for the shielding element.
    The splinter protection fabric in this way provides increased safety for the shielding element when an accelerated body strikes, in particular projectiles or splinters.
    The splinter protection fabric used acts as a laminate in combination with the shielding element. In particular in the event of an effect which otherwise deforms the shielding element plastically, the splinter protection fabric can function as a tension element, which leads to a minimization of the deformation of the shielding element. In total, the splitter protection fabric within certain limits protects against the shielding element ceasing to function prematurely. In particular in the form of a laminate, the shielding element can sometimes be thinner in that the strength of the shielding element, which is then reduced, is at least compensated by the splinter protection fabric.
    In principle, the splinter protection fabric can also at least partially cover the first and second components. In this way, the splinter protection fabric can also be arranged on the components at the gap above the shielding element.
    Depending on the type of design, the splinter protection fabric may be flexible or not _15- flexibly designed. The splinter protection fabric can also fulfill appearance properties so that it looks, for example, like a decorative strip or a similar fitting or cladding component. In this way, the splinter protection fabric can be arranged in the visible area of the gap and generally at the splitter protection device.
    Another principal idea of the invention is that the shielding element and the connecting element are bent towards each other. In this way, the connecting element and the shielding element have a bend which is mutually opposite. The special advantage then consists in a simple connection of the connecting element to the component in question, in particular if it is also bent. In this way, the connecting element should preferably be connected to the respective component at the top so that there is at least partially a line of contact between the connecting element and the component.
    The components that form the shield or limit a shelter are in principle made of protective steel. The other elements of the splinter protection device can also be completely made of protective steel. Of course, the additional elements of the splitter protection device can also be formed of non-protective steel. This is especially true for those areas that cannot be hit immediately by an accelerated object.
    As an example of this, the intermediate element can be mentioned. Despite this, the various components and elements of the splinter protection device can also consist of other materials or consist of these whose properties are considered to be bulletproof and / or explosion-proof.
    If the splitter protection device is constructed of several components of protective steel and / or other steel alloys and / or other shelling and / or explosion-proof materials, these components must be connected to each other material-sealing and / or force-sealing. In the case of a material-closing connection, welded joints and / or adhesive joints are conceivable.
    The shatter protection device's various components and elements resp. the elements in the splinter protection device which consist of resp. comprises steel, in particular protective steel, can be both wholly or partly at least partially made by hot-forming and / or press-cooling. Depending on requirements, these can also be goal-oriented and thus only to a certain extent be hardened.
    Within the scope of the invention, in particular the various components which constitute the direct outer casing can be an armored construction. As an alternative to this, the components can also be mounted as a complement to a durable housing.
    In this way, for example, an outer structure formed of body steel can be supplemented by the splinter protection device according to the invention within the scope of the invention. Then the various components and elements can either be arranged on the outside of the motor vehicle or behind the outer structure. In this way, a motor vehicle in particular can correspond in series production to the appearance so that any armored construction is not visible to the outside.
    The invention introduces a splitter protection device with considerably improved efficiency. In this way, the created shield must be designed as a welding structure right up to the gaps required as an unimpeded armored structure. The problematic skew due to the application of welding heat at the current technical development level is effectively avoided by placing the necessary welds close to the edges. In addition, the preset strength is maintained up to the edges. Any weakening of the edges is effectively compensated by using the shielding element.
    In particular, the use of the intermediate element reduces the cross-sectional jump and the varying stiffness of adjacent areas associated therewith to a minimum. Thanks to this, the different bending properties and the risk of deformation of this type of structure are reduced due to high shear forces that are associated with it in terms of construction. The result is an armored construction that can handle significantly higher loads.
    The invention is explained in more detail below with the aid of some schematically illustrated embodiments.

    Figure 16 shows a further alternative type of embodiment of the splinter protection device according to the invention from Figures 6 and 15 in the same way.
    Figure 1 shows an armored structure 1 in the form of a side area of an armored motor vehicle. The armored structure has a first component A in the form of a side part of a body. Its necessary openings must always be closed with a second component B in the form of doors. In its capacity as a door, the second component B can thus be moved in relation to the second component A. Between the components A and B there is a structural space 2. The various components A and B are also partly made of protective steel so that the areas are particularly vulnerable to shelling and / or blasting on the protective cover created in this way can be seen in column 2.
    Figure 2 shows a cross section through the armored structure 1 of figure 1 at the gap 2. In the present case it is a known shatter protection device _19-3 at the current technical development level which has a connecting element 4 and a shielding element 5. The shielding element 5 is attached to the first component A over the connecting element 4. The shielding element 5 then extends parallel to the first component A and has a distance therefrom via the connecting element 4. The shielding element 5 is then arranged in the area at the gap 2 so that the shielding element 5 bridges the gap 2. Through the arrangement of the connecting element 4, the shielding element 5 also has a distance from the second component B with a thickness c of the connecting element 4. In this device, both the connecting element 4 and the shielding element 5 face an inner space 6 in the armored structure. The inner space 6 is consequently shielded against an outer area 7, more specifically the components A, B and the splitter protection device 3. In order to have as tight a closure as possible between the inner space 6 and the outer area 7 at the gap 2, a seal 8 which is in contact therewith is mounted. between the second component B and the shielding element 5.
    Figure 3 shows a splitter protection device 3a compared to figure 2.
    The splitter protection device 3a also has a connecting element 4a and a shielding element 5a. The shielding element 5a is connected to the connecting element 4a via a clearly visible welded joint 9. In addition, a seal 81 which is in contact with it is arranged between the shielding element 51 and the second component B.
    Unlike Figure 2, the connecting element 4a in the present case is attached directly to the first component A via an intermediate element 10. Through the two elements 4a, 10 which connect the shielding element 5a and the first component A which connects it, the shielding element 5a has a distance d from the second component B so that the seal 8a bridges the distance d.
    The intermediate element 10 is at least partially attached to the first component A via a welded joint 11. The welded joint 11 is then arranged along an edge area 12 of the first component A which runs along the gap 2. The intermediate element 10 and the connecting element 4a are connected to each other via another welding joint 13 is. Welded joints 9 and 13, which connect the connecting element 4a to the shielding element 5a and the intermediate element 10, are arranged on a side of the connecting element 4a which faces away from the seal 8a. In the present invention, the connecting element 4a is arranged at a distance 3 from the edge which delimits the first component A towards the gap 2 compared with the illustration in figure 2.
    The intermediate element 10 itself has a width f where the distance e between the connecting element 4a and the edge of the first component A amounts to 56% of the width f of the intermediate element 10. A thickness c1 of the intermediate element 10 extending perpendicular to the plane of the first component in the present case amounts to 33% of a thickness g for the first component A.
    Figure 4 shows a detailed change of splitter protection device 3b which has a projection 15 compared to the splitter protection device 3a in figure 3 which is arranged on the shielding element 5a. In the case of the projection 15, this is a separate component which is connected to the shielding element 5a via a welded joint 16. The projection 15 is then arranged on a free end 17 of the shielding element 5a which lies opposite the welded joint 9 against the welded joint 4a. The projection 15 is arranged on the same side of the shielding element 5a as the connecting element 4a so that the projection 15 extends in the direction of the second component B.
    Figure 5 shows an alternative type of embodiment of the splitter protection devices 3a, 3b in Figures 3 and 4 with a splitter protection device 3c. Compared with the intermediate element 10 extending at right angles and the shielding element 5a in Figures 3 and 4, the splitter protection device 3c has curved elements 5b and 10a. Taking into account the illustration in Figure 5, the shielding element 5b is bent around the seal 8a while the connecting element 10a is bent opposite compared to the bend of the shielding element 5b. The shielding element 5b and the connecting element 10a are thus bent opposite each other. This results in the connecting element 10a having a line of contact with the first component A so that the free edge area of the connecting element 10a is bent away from the first component A. Analogously to Figures 3 and 4, the curved connecting element 10a is also connected to the first component A via a welded joint 18 in the edge region of the first component A.
    Due to the curved shape of the connecting element 10a, this can be locked to a similarly curved component A, which is not shown in more detail here. Compared with the illustration in Figure 8, the present splinter protection device 3c in Figure 5 has the advantage that the shielding element 5b is made separated from the connecting element 10a, which leads to the connecting element 10a being easily locked to the first component A via the welded joint 18.
    In this way, the shielding element 5b in the present case is connected to the connecting element 10a via a further welding joint which is opposite the welding joint which is for locking the connecting element 10a to the first component A. Due to the bend of the shielding element 5b running around the seal 8a in addition, a projection 15a extending in the direction of the second component B. The projection 15a then forms a part of the shielding element 5b in a piece of uniform material.
    Figure 6 shows a further alternative type of embodiment of a shatter protection device 3d which also has a curved shielding element 5c compared to the illustration in figure 5. The shielding element 5c is then also bent around the seal 8a so that the projection 15a results in a part of the shielding element 5c in uniform material in one piece on one side. In contrast to the splitter protection device 3c in Figure 5, the shielding element in the present case is fixed directly in the edge region of the first component A via a welded joint 20. The edge region 21 of the shielding region 4c extending over the welded joint 20 has no curved course but a rectilinear course parallel to the course of the first component A.
    Figure 7 shows a detailed change of splitter protection device 3e for illustration of Figure 6. In the same design of the shielding element 5c, this is in the present case connected to the first component A via the welded joint 20 over a further welded joint 22 on its edge area 21. Figure 8 shows a further splitter protection device 3f anticipated in Figure 5.
    Compared with the illustration in Figure 6, the splitter protection device 3f also has a shielding element 5d which is bent around the seal 8a, which means that the part of a piece of uniform material in the form of the projection 15a is directed towards the second component B. In contrast to Figure 6, the shielding element 5d at its attachment to the first component A one opposite it and thus a bend 23 of its edge region 21 which is directed towards the projection 15a.
    The opposite bend 23 of the shield element 5d at the first component A takes place analogously to the bend of the connecting element 10a in Figure 5. As a result, the shield element 5d has a cross section in the form of an S where the shield element 5d is further attached via a weld 24 in the edge region .
    Figure 9 shows a further alternative design of a splitter protection device 3g. The splitter protection device 3g also has a shielding element 5e whose basic shape substantially corresponds to the shielding element 5c in Figures 6 and 7.
    In contrast, on the one hand, the edge region 21 of the shielding area 5e is further away from its bend around the seal 8a, and on the other hand, the first component A has a projection 26 on its edge region 12 which runs along the gap. In comparison with the illustration in Figure 6, the first component A at the projection 26 folds back to the inner space 6 from the outer area 7 with its edge area 12. In the present case, the projection 26 is a bend of the first component A in its edge area. The edge region 21 of the shielding element 5e is arranged in the receding part of the first component A and is glued to the first component A via an adhesive joint 27. The shielding element 5e has an edge 28 which is inclined towards the plane of the first component A at an edge region 21 so that it the first component A has a course corresponding to the first component A at the edge 28.
    Figure 10 shows the same principle for a splinter protection device already known from Figure 9. Here too, the edge region 21 of the shielding element 5e engages in a projection 26a in the first component A. However, in contrast to the illustration in Figure 9-23, the projection 26a is not formed by a bending of the edge region 12 of the first component A but by reducing the thickness g1 of the edge region 12 of the first component A. Above the inclined edge 28 in the edge region 21 of the shield region 5e, the first region 12 of the first component A also has a course which is adapted to the shield element 5e. . As a result, the shielding element 5e is supported over its edge area 21 also against the first component A via its upper piece 25 and is glued to it via an adhesive joint 27. In addition, the edge 14a which delimits the second component B against the gap 2 also has a course which is adapted to the course for the upper part 25 of the shielding element 5e and thus has an inclined course.
    The projections 26a of the first component A are then designed so that the edge region 21 of the shielding element 5e grips the projections 26a of the outer region 7.
    The general advantage of the shielding area 5e gripping around the projections 26, 26a of the outer area 7 is based on the fact that this can be supported against the first component A under load. In other words, a force shock which comes to the shielding element 5e from the outer area 7 and the impulse this gives rise directly to the first component A. The connection between the first component A and the shielding element 5e is then substantially loaded with pressure. Against this, corresponding tensile forces occur in combination with the first component A at a fixed element from the inner space 6 to the first component which leads to a high stress on the connection, in particular at a dynamic load.
    Figure 11 shows an almost identical type of embodiment of a shatter protection device 3i with respect to the illustration in Figure 10. Unlike the shatter protection device 3h in Figure 10, the present projections 26a on the first component A are then designed so that the edge region 21 of a shielding element 5f is arranged from the inner space 6 in the projection 26a. In this position, the shielding element 5f is connected to the first component A via the adhesive joint 27. Figure 12 shows a further type of embodiment of a splitter protection device 3j.
    The splitter protection device 3j comprises a shielding element 5g which has a totally curved cross section. In addition to the protrusion 15a located on the free edge 17, this has a bend 29 reminiscent of the protrusion 15a in the edge region 21 opposite its protrusion 15a. In other words, the shielding element 5g lies cup-shaped around the area of the gap 2 on the armored structure. Then both the projection 15a and the bend 29 are directed towards the components A and B. The shielding element 5g is then attached to the first component A via a connecting element 4b.
    The connecting element 4b then extends at a right angle from the first component A into the inner space 6 and is connected to the first component A via a welded joint. In the case of the shielding element 5g, the connecting element 4b is arranged between the projection 15a and the bend 29.
    The shielding element 5g has through openings 31 which are arranged at the connecting element 4b. The shielding element 5g is then welded to the connecting element 4b through the openings 31. In the present case it is thus a hole welded joint.
    Figure 13 shows a detailed modified splitter protection device 3k which substantially corresponds to the splitter protection device 3j in figure 12. Compared with the illustration of figure 12, a connecting element 4c in the present case is arranged between the first component A and a shielding element 5h. The connecting element 4c has at least one pin-like projection 32 via which the connecting element 4c is at least partially arranged through the opening 31 in the shielding element.
    Figure 14 shows a splitter protection device 31 which substantially corresponds to the splitter protection device 3k in figure 13. Compared with the illustration in figure 13, the pin-like projection 32 is more pronounced in the present case, which means that the connecting element 4c with its projection 32 extends through the opening 31h. In this design, hole welding is no longer possible, which means that the shielding element 5h is connected to the connecting element 4c via an external welding joint 33.
    Figure 15 shows another splitter protection device 3m. It serves as an example for all existing and future splinter protection devices within the scope of this invention. In this connection, a clarification is to be made of a design of the edges 14 and 14a which lie opposite each other at the gap between component A and B in the present invention. The edges 14 and 14a which lie opposite each other at the gap 2 between components A and B are aligned parallel to each other and inclined towards the outer surface 34 of the first component A which points towards the outer area 7. In other words, the edges 14 and 14a have another angle h than 90 ° to the outer surface 34 of the first component A. In the present case, the angle h to the outer surface 34 of the first component A amounts to 45 °. In the case of a normal to the outer surface 34 of the first component A, the edges 14, 14a have an overlap at the gap 2.
    Figure 16 further clarifies a type of embodiment of a splitter protection device 3n which serves as an example for all splitter protection devices 3a to 3m shown so far. In the present case, the shielding element 5c leaning against the illustration in Fig. 6 has a splinter protection fabric 35 in an area facing the gap 2. The splinter protection fabric 35 is then arranged in the area around the bend of the shielding element 5c made around the seal 8a and further extends over the welding joint 20 via which the shielding element 5c is fixed to the first component A.
    In principle, the splitter protection fabric 35 can also extend over the shielding element at the gap 2. Preferably, the splitter protection fabric 35 should extend from the shielding element 5c into the gap 2 where it is connected to the edge 14b of the first component A which lies opposite the second component B. The particular advantage is that the splinter protection fabric 35 functions as a composite component in combination with the shielding elements 5c. In this way, the tensile forces present on the shielding element 5c when loaded are taken up directly by the splitter protection fabric 35 and transferred to the first component A. In addition to the increased dimensional stability against bending of the shielding element 5c which this leads to the splitter protection fabric 35 arranged in this way. a relief of the welded joint 20. Of course, the splitter protection fabric 35 can also grip around outside the edge 14b of the first component A and in this way be at least partially arranged from the outer area 7 of the first component A.
