Description

The invention relates to a restraint element according to claim 1 for a restraint system, in particular for mobile use and / or for temporary traffic safety in the area of traffic routes.

Furthermore, the invention relates to a restraint system according to claim 11 for traffic safety on traffic routes, comprising at least a first and a second restraint element.

Restraint systems for traffic safety are passive protective devices that are preferably attached or set up on traffic routes, such as streets and highways. Restraint systems are generally used to secure traffic against hazards, in particular to secure during construction site work or other work along a traffic route, to secure on mountain slopes against falling debris or to protect against water. Restraint systems are also used to protect traffic against any vehicles leaving a lane and to protect people, facilities and buildings.

Restraint systems can be arranged at different positions along a traffic route, for example at the edge of a traffic lane or between two traffic lanes running in opposite directions, in order to separate traffic directions running in opposite directions from one another.

Restraint systems for traffic safety on traffic routes can in particular be designed to stop or deflect impacting vehicles and / or around those that are released upon impact with a vehicle At least partially absorb energy, in particular through limited yielding and / or displacement of the restraint system.

In order to ensure the resilience of a restraint system in the event of a collision, restraint systems are only anchored firmly to an underlying surface in exceptional cases. It is therefore advantageous to connect the restraint elements of a restraint system to one another, for example under tension.

From the DE 10 2008 026 661 A1 Retention elements for a restraint system with the features of the preamble of claim 1 are known. The known retaining elements have a recess on a first end face and a projection on a second end face opposite the first end face. In the known restraint systems, the first end face of a first restraint element engages with the projection in the second end face of a second restraint element in the region of the recess.

A disadvantage of the aforementioned prior art is that the previously known restraint elements for a restraint system only allow a relatively small area connection of their end faces - in particular when loading in a direction transverse to the extent of the restraint system. As a result, when a vehicle hits the restraint system, individual restraint elements can break out or be damaged in the area of the aforementioned engagement. Such damage to the restraint system requires a complex, costly and sometimes risky repair of the restraint system, such as the replacement of individual restraint elements. The repair of a restraint system in the area of the traffic route can often lead to permanent and serious traffic obstructions.

On the basis of this prior art, the present invention is based on the object of providing restraint elements for restraint systems which enable a more stable bond.

Another object of the invention is to provide a restraint system formed from such restraint elements which Restraint system has a more stable connection between the restraint elements.

This object is achieved according to the invention by a restraint element with the features of claim 1 and by a restraint system with the features of claim 11. Advantageous further developments are the subject matter of subclaims.

A restraint element according to the invention is provided for a restraint system for traffic safety on traffic routes, in particular for mobile use and / or for temporary traffic security in the area of traffic routes. For this purpose, the retaining element has a base body which has a longitudinal extension with a length, a vertical extension with a height and a transverse extension with a width, in which the length is preferably greater than the height and / or than the width, and which is particularly preferably plate-shaped (or cuboid) is formed. The retaining element has at the end in the direction of the longitudinal extension at least one end face which is designed to connect the retaining element to a further, preferably identical, retaining element. The retaining element according to the invention is characterized in that the end face has at least one region in which the end face has an angle greater than or equal to 0 degrees and less than 90 degrees with respect to the longitudinal extension, which region extends over the entire width; and / or that the end face has at least one region in which the end face has an angle greater than 0 degrees and less than 90 degrees with respect to the longitudinal extension, which region extends over the entire height.

According to the invention it is therefore provided that the end face - in relation to the longitudinal direction of the retaining element or its base body - extends obliquely or specifically diagonally. The area available for connecting two retaining elements to one another can be enlarged in this way, as a result of which the above-mentioned disadvantages from the prior art can be avoided or mitigated.

In other words, in a first variant, the area has, both in a side view of the retaining element and in a longitudinal section through the Retaining element perpendicular to the transverse extent in the area of its end face at the aforementioned angle with respect to the longitudinal extent. In a second variant, both in a top view of the retaining element and in a longitudinal section through the retaining element perpendicular to the vertical extent in the area of its end face, the area has the aforementioned angle with respect to the longitudinal extent. According to the invention, both variants can also be combined.

According to the first variant, the longitudinal section perpendicular to the transverse extension through the retaining element marks a cutting line which divides the end face. A viewer who looks at the retaining element in the direction of the transverse extent perceives the area as a straight line. According to the invention, this can now be oriented at an angle greater than or equal to 0 degrees and less than 90 degrees with respect to the longitudinal direction. The end face runs in a straight line and, in the event that the angle is greater than zero degrees, correspondingly obliquely (especially diagonally, in particular if the angle is 45 degrees) to the longitudinal direction.

The end face of the retaining element can also - as already mentioned - according to the second variant of the retaining element according to the invention, additionally or alternatively, in a longitudinal section perpendicular to the height extension, have at least one area in which the end face is at an angle greater than 0 degrees and less than 90 degrees with respect to the longitudinal extension so that there is again an inclined (especially diagonal) course with respect to the longitudinal direction in this area. The angle mentioned is thus an acute angle. The longitudinal section perpendicular to the vertical extension through the retaining element defines a cutting line which divides the end face. A viewer who looks in the direction of the height extension perceives the area as a straight line. All angles here and below include a customary manufacturing tolerance.

A restraint system according to the invention for traffic safety on traffic routes, in particular for mobile use and / or for temporary traffic safety on traffic routes, comprises at least a first retaining element according to the invention and a second retaining element according to the invention, preferably two identical retaining elements, which retaining elements are connected to one another via facing end faces.

In the context of this description, the term traffic route preferably and not exclusively includes all types of land traffic routes, motor vehicle roads, motorways, roads, race tracks, paved paths, paths, tunnels, bridges, cycle paths, pedestrian paths, carriageways, lanes, railway lines, railways, ski slopes, waterways, Sea routes, inland waterways, canals, runways and places as well as other traffic routes known to those skilled in the art, on which restraint systems of the type in question can be used.

The term vehicle preferably and not exclusively includes land vehicles, motor vehicles, bicycles and other human-powered vehicles, carriages and other animal-powered vehicles, trains, watercraft, ships, boats, aircraft and other vehicles known to those skilled in the art.

The main body of the retaining element is preferably plate-shaped, for example as a flat cuboid, in which one (width) dimension is significantly smaller than the other dimensions, but can also have other geometries, such as a cubic shape (cube), a prismatic shape, a cylindrical shape or a curved and / or curved shape.

The terms longitudinal extension, transverse extension and vertical extension span a coordinate system, preferably a Cartesian coordinate system, and serve as general directional information; here and in the following, they not only relate to the base body, but also relate to other features of the retaining element. The longitudinal extension is synonymous with the longitudinal direction for directions.

The terms length, width and height initially relate only to the base body of the restraint element and not to any additional base or base plate that may be used to set up the base body on a substrate. It is not mandatory that length, Width and / or height of the base body are constant; for example, the width of the base body can be different depending on the height, for example if the shape of the retaining element deviates from a cuboid shape.

An advantage of the retaining element according to the invention is that it has an area on the end faces which extends over the entire width and / or the entire height and can be used to form a stable bond with another retaining element, so that a large-area connection area is available .

In the context of this invention it has also been recognized that a lower limit for the amount of said angle is preferably greater than 10 degrees, further preferably greater than 20 degrees, further preferably greater 30 degrees, further preferably greater 40 degrees, further preferably greater 50 degrees, further preferably greater 60 degrees, further preferably greater than 70 degrees and further preferably greater than 80 degrees. In the context of this invention it has also been recognized that an upper limit for the amount of said angle is preferably less than 80 degrees, more preferably less than 70 degrees, more preferably less than 60 degrees, more preferably less than 50 degrees, more preferably less than 40 degrees, further preferably less 30 degrees, further preferably less than 20 degrees and further preferably less than 10 degrees, the upper limit being selected to match the respective lower limit (ie greater) in each case. By varying the inclination of the area of the end face, a variation in the stability of the restraint system in the event of an impact can be achieved.

In a first development of the retaining element according to the invention, at least one end face has at least one area which has an angle between 35 and 55 degrees, preferably a diagonal with an angle of approximately 45 degrees with respect to the longitudinal extent.

As an alternative or in addition, this includes both longitudinal cuts perpendicular to the vertical extent and longitudinal cuts perpendicular to the transverse extent.

An angle greater than 30 degrees and less than 60 degrees, preferably an angle of approximately 45 degrees, has proven to be particularly advantageous, which can correspond exactly to a diagonal, since in this way a particularly high stability of the restraint system against an impact can be achieved. In other situations, however, it can be advantageous to select a different angle value, for example in order to increase the flexibility of the restraint system. As a result, part of the energy acting on the restraint system during the impact can be converted by shifting and / or deforming the restraint system, whereby an impacting vehicle is braked more strongly.

In another development of the retaining element according to the invention, the end face has at least one recess and / or at least one projection which preferably extends or extends in the direction of the longitudinal extension and / or the transverse extension.

A first development of the restraint system according to the invention provides that at least one projection of the first end face of the first restraint element engages in at least one recess of the second end face of the second restraint element.

By means of such recesses and / or projections, two retaining elements can be geometrically defined and particularly stable connected to one another via their end faces and preferably also detached from one another again, particularly preferably non-destructively, wherein the recesses and projections can interact according to a tongue-and-groove principle to in particular to achieve a stiffening in the direction of the transverse extension. The recesses and / or projections can also exercise a kind of centering function when connecting.

In a further development of the retaining element according to the invention, a first end face is arranged on a first end of the retaining element and a second end face is arranged on a second end of the retaining element, which second end is arranged opposite the first end.

By providing a retaining element with a respective end face at two ends, the retaining element can be connected to a Connect another retaining element. As a result, a restraint system can be created that comprises a plurality of restraint elements which are stably connected to one another.

The first end face and the second end face can be designed to be identical or complementary to one another. In the event that the two end faces are of identical design, two different types of restraint elements are generally required to produce a restraint system. In the case of identical end faces, the first retaining element can have a projection both on the first end face and on the second end face, whereas the second retaining element can have a recess (complementary to the mentioned projections) on the first and second end faces.

However, it is particularly advantageous to use retaining elements with different, preferably complementary, end faces, because then basically only one type of retaining element has to be kept available for producing a retaining system.

A further development of the retaining element according to the invention provides that the first end face has the at least one protrusion and the second end face has the at least one recess, the protrusion and recess preferably being designed to be complementary to one another, particularly preferably such that the protrusion after the tongue and groove Principle can be positively inserted into the recess of a further, preferably identically designed retaining element and also removed therefrom.

The tongue and groove principle enables a particularly effective, form-fitting and stable connection between two retaining elements. Because the connection between two restraint elements can be detached, the restraint system can also be easily assembled and dismantled.

For temporary traffic safety in particular, it is advantageous if the connection between two retaining elements can be released without being destroyed. This allows the restraint system to be used repeatedly and flexibly at different locations.

In a further embodiment it is provided that the end face of the retaining element comprises a horizontal connecting section which is arranged on an upper side of the base body opposite the base and / or on a mounting surface of the base body facing the base. In addition, the retaining element can also comprise an inclined connecting section which is arranged in the aforementioned area of the end face. The inclined connecting section thus also has the aforementioned angle with respect to the longitudinal extension. Both in the horizontal connecting section or in the horizontal connecting sections as well as in the inclined connecting section, two adjacent retaining elements of a restraint system can engage with one another by means of a tongue and groove connection, whereby a higher stability of the restraint system can be achieved. The groove is preferably provided on the first end face, and the tongue is preferably provided on the second end face.

In an advantageous development of this embodiment, it is also provided that in the horizontal connecting section or in the horizontal connecting sections and / or in the inclined connecting section, the end face provided with the groove has an additional tongue within the groove and / or that the end face provided with the tongue has an additional groove in the area of the tongue. The interlocking of this additional tongue and the additional groove results in a double tongue and groove connection, which ensures additional stability of the restraint system against impacting vehicles.

Another embodiment of the retaining element provides that the end face has at least a first area and a second area and preferably also a third area. These areas can be arranged adjacent to one another in the direction of the longitudinal extent and / or in the direction of the transverse extent, and the respective adjoining areas can have a different angle with respect to the longitudinal extent and / or the transverse extent. As a result, the end face is stepped. These different angles of the adjoining areas preferably have a difference of approximately 90 degrees from one another.

By designing the end faces with several areas which have different angles with respect to the longitudinal extent and / or the transverse extent, an even more stable combination of two restraint elements can be created, and the forces that occur in the event of an impact can be diverted particularly well within the restraint system and / or be redirected.

It is also within the scope of the present invention to provide a retaining element in which the at least one end face is step-shaped.

Such a step-shaped configuration of the end face makes it possible to create a more stable connection between two retaining elements. In addition, easier detachment of the retaining elements from one another is made possible.

It is also within the scope of the present invention to provide a restraint element or a restraint system which comprises at least one (lateral) impact surface (or generally a side surface) that extends in the direction of the longitudinal extension.

The term impact surface preferably and without limitation includes a flat surface, a curved surface, a surface according to the so-called "New Jersey type", the "Jersey type", the "Step type", the "F-shape" Type ", the" Constant Slope Type "and other impact surfaces known to those skilled in the art.

The impact surface is particularly suitable and provided for diverting an impacting vehicle back into the lane. This prevents the vehicle from entering a danger area or an opposite lane. The differently designed impact surfaces represent various compromises between installation stability and (as small as possible) installation area (space requirement).

In yet another further development of the retaining element according to the invention, the retaining element has a base or base plate, which is preferably arranged on an underside serving to erect the retaining element and preferably extends over the entire width of the base body or extends beyond this. This has already been pointed out earlier.

The base plate and base body are preferably designed as two elements that can be connected to one another and again (non-destructively) detached from one another.

The base body and base plate can be connected to one another via a connecting means. The base plate can have a recess with a shape and dimension corresponding to the base body, so that the base body can be at least partially inserted into the base plate. The base plate can be connected to an underlying substrate, for example with a connecting means. A bond between the base plate and the subsurface is particularly advantageous when additional stiffening of the restraint system is desired.

One advantage of providing a base plate is that it enables the retaining element to stand better on the ground because the weight of the retaining element can be distributed over a preferably larger contact surface. In addition, the base plate can be used to increase the stability of the restraint element or restraint system in relation to vehicles impacting from the side.

However, the retaining element can in principle also be designed without a base plate. In this case, the main body of the restraint element can be placed directly on an underlying surface or connected to the underlying surface, in particular using a connecting means.

A further development of the retaining element according to the invention provides that the retaining element, especially the base body, is formed from at least one building material, preferably from a solid building material, particularly preferably from concrete; and is preferably reinforced with additional reinforcement elements, particularly preferably with steel reinforcement elements.

The term building material preferably and not exclusively includes cement, natural stone, sand, gravel, crushed stone, clay, glass and glass fibers, metals such as steel, organic building materials, wood, plastics, recycled building materials, other building materials known to those skilled in the art and / or combinations of different building materials.

The reinforcement elements can have a higher strength, such as, for example, a higher tensile strength and / or a higher elasticity, than the building material in order to dissipate impact energy in an advantageous manner. The composite construction ensures additional stability of the individual restraint element.

It is also within the scope of this further development to provide a retaining element which comprises a frame that can be or is filled with building material, preferably a steel frame, which is or can be filled with building material, preferably with concrete or the like.

Such a construction enables the retaining elements to be produced quickly and inexpensively. The formwork (the frame) can be removed after filling with building material or remain as part of the retaining element.

Another development of the restraint system according to the invention provides that the mutually facing end faces of two restraint elements define a free space between them, preferably a cuboid or prismatic free space, that is, do not touch each other over their entire surface.

In principle, there is no direct connection between the two retaining elements within the free space, which is accordingly formed between two retaining elements.

In a further development of the restraint system according to the invention, it is therefore provided that it comprises at least one additional connecting element which has a shape and dimensions that can be inserted into the free space and which can be inserted or inserted into the free space via their end faces accordingly for connecting two restraint elements, preferably with the end faces of the retaining elements enters into (mechanical) interaction. In this way, the connecting element can ensure a continuous and full-surface connection between the retaining elements.

Such a connecting element can preferably have a cuboid or prismatic shape, depending on the shape of the corresponding free space.

By using a connecting element, all of the end faces of the retaining elements involved can be configured identically in a simplified manner. In this case, the restraint elements of the restraint system are joined to one another via the additional connecting element, as a result of which, in particular, the manufacturing costs can be reduced through the aforementioned simplification (in this case through identically designed end faces). In addition, there is a simplified handling during transport and setting up the retaining elements, since it is not necessary to pay attention to the mutually matching orientation of the end faces (the end faces are preferably all identical); this is particularly advantageous when the restraint elements are used for temporary traffic safety.

An alternative embodiment of the restraint system according to the invention provides that the restraint elements are fastened to one another at least in the area of their end faces with at least one connecting means, preferably screwed, mortised or bolted; or that the retaining elements are each fastened to the connecting element with at least one connecting means, at least in the region of their end faces. The connection means can be used to brace the individual restraint elements against one another (formation of a so-called tension-compression shock between adjacent restraint elements), which has a positive effect on the restraint effect of the overall system.

The term connecting means preferably includes, without limitation, screws, tenons, bolts, dowels, hooks, nails and other connecting means known to those skilled in the art.

By using the connecting means mentioned, the connection between two retaining elements can be additionally reinforced, in particular by generating a certain tensile stress, as already mentioned above. The connecting means are preferably non-destructive again from the connecting elements solvable. As a result, the restraint system - as already mentioned - can be dismantled again in a simple manner and can be used again at a different location.

The use of the connecting means mentioned is not restricted to the use of the connecting elements mentioned. They can also be used to connect retaining elements without the "interposition" of connecting elements, as is known in principle to the person skilled in the art.

The same reference symbols used in the figures denote elements that are the same or at least have the same effect.

Figure 1 shows a first restraint element 1.1 and a second restraint element 1.2 of a restraint system 2 in a longitudinal section perpendicular to the transverse extent 3. The restraint elements 1.1, 1.2 comprise a base body 4 with a height 5 (measured in the direction of a height extent 6), a width 13 (in Figure 3 shown, measured in the direction of the transverse extension 3) and a length 16 (in Figure 3 shown, measured in the direction of the longitudinal extension 9). The base body 4 is arranged on a base plate 7 which is used to set up the retaining elements 1.1, 1.2 on an underlying substrate 8, for example a road surface. The retaining elements 1.1, 1.2 adjoin one another in the direction of their longitudinal extension 9 with their end faces 10.1, 10.2.

The circle symbol with the point located therein, which symbolizes the transverse extent 3 in the example of FIG. 1, implies a directional arrow perpendicular to the plane of the drawing, which points towards the viewer. The vertical extension 6, the transverse extension 3 and the longitudinal extension 9 or the corresponding spatial directions form a (Cartesian) coordinate system.

The end faces 10.1, 10.2 of the two retaining elements 1.1 and 1.2 have, in a longitudinal section perpendicular to the transverse extent 3, an area 11 in which the end faces 10.1, 10.2 form an angle 12 greater than 0 degrees and less than 90 degrees, especially about 50 degrees, with respect to the longitudinal extent 9 have. The area 11 extends over the entire width 13 of the two retaining elements 1.1 and 1.2 or their base body 4 (the width 13 is in Figure 1 not shown, see for this Figure 3 ). The arrangement of the base body 4 on or on a base plate 7 is not absolutely necessary, but can be advantageous in order to enable the retaining elements 1.1 and 1.2 to stand better on the substrate 8.

Figure 2 shows the restraint system 2 Figure 1 in a side view with a view of the one side or impact surface 14 of the two retaining elements 1.1 and 1.2. In the perspective shown, the impact surface 14 faces the viewer.

As already mentioned above, the area 11 extends over the entire width 13. This is shown in particular in FIG Figure 2 can be seen, since the edge of the end faces 10.1, 10.2 can also be seen along the impact surface 14 - here as a straight line. The section AA is in Figure 7 shown.

Figure 3 shows a restraint system 2 with restraint elements 1.1, 1.2 in a plan view. The restraint system 2 is attached to traffic safety between two traffic routes 15 - here lanes. Each retaining element 1 has a base body 4 with a length 16 and a width 13. On the side of the retaining elements 1.1, 1.2 facing the traffic route 15, they each have an impact surface 14. The two retaining elements 1.1 and 1.2 are aligned in the direction of their longitudinal extension 9 next to one another or one behind the other, as shown. A first end 17.1 of the one retaining element and a second end 17.2 of the other retaining element face one another, the end faces 10.1, 10.2 of the retaining elements 1.1, 1.2 adjoining or abutting one another. The section BB, perpendicular to the longitudinal extension 9, is in Figure 5 shown.

Figure 4 shows a restraint system 2 with restraint elements 1.1, 1.2 in a plan view, which is attached to the outer edge of a traffic route 15. In comparison to Figure 3 the restraint elements 1 have only one impact surface 14 facing the traffic route 15.

Such a peripheral attachment of the restraint system 2 along a traffic route 15 is used, for example, when the traffic route 15 is to be secured on one side against an area 18 to be demarcated. Such a region 18 to be delimited can, for example and without restriction be a construction site, a slope, an area at risk of landslide or another danger zone.

Figure 5 shows one of the retaining elements Figure 3 , here generally denoted by the reference numeral 1, in cross section BB perpendicular to the longitudinal extension 9. The retaining element 1 comprises a base body 4 with a height 5 in the direction of the vertical extension 6 and a width 13 in the direction of the transverse extension 3. In the illustration shown here is the End face 10 with the area 11, which extends along the entire width 13, facing the viewer.

Depending on the area of application of the restraint element 1, the impact surface 14 can be located on one or on two sides parallel to the longitudinal extension 9.

In Figure 6 a side view with a view of the first restraint element 1.1 of a restraint system 2 is shown. The longitudinal section CC perpendicular to the vertical extension 6 is in Figure 8 pictured.

Figure 7 shows the cross-section AA perpendicular to the longitudinal extension 9 from FIG. 2. The base plate 7 preferably extends over the entire width 13 of the base body 4 and even protrudes laterally (in the direction of the transverse extension 3) beyond it, in particular to enlarge a set-up area.

In Figure 7 it becomes clear that the height 5 relates to the base body 4 without the base plate 7.

Figure 8 shows a restraint system 2 with a first restraint element 1.1 and a second restraint element 1.2 according to the longitudinal section CC Figure 6 , which is perpendicular to the vertical extension 6. The end face 10 has a region 11 which has an angle 12 of approximately 50 degrees with respect to the longitudinal extension 9. The area 11 extends over the entire height 5 (not shown here, see Figure 6 ) of the retaining elements 1.1 and 1.2.

Figure 9 shows a first retaining element 1.1 in a longitudinal section perpendicular to the transverse extension 3. The first retaining element 1.1 has a first End 17.1 has a first end face 10.1. The first end face 10.1 has a recess 19. The end face 10.1 also comprises a first area 11.1 and a second area 11.2. The first area 11.1 and the second area 11.2 each have different angles with respect to the longitudinal extension 9.

The first area 11.1 is oriented at an angle 12 of 90 degrees with respect to the longitudinal extension 9. The second area 11.2, on the other hand, has an angle of 0 degrees with respect to the longitudinal extension 9. The end face 10.1 is in Figure 9 thus formed step-shaped.

Figure 10 shows a second retaining element 1.2, which is preferably identical to that in Figure 9 shown first retaining element 1.1 is formed. In Figure 10, the second end 17.2 of the second retaining element 1.2 is shown. The second end 17.2 has a second end face 10.2 with a projection 20. The second end face 10.2 comprises a first area 11.1 which has an angle of 90 degrees with respect to the longitudinal extension 9, and a second area 11.2 which is oriented at an angle of 0 degrees with respect to the longitudinal extension 9.

Figure 11 shows a restraint system 2, in which a first restraint element 1.1 according to Figure 9 with the second retaining element 1.2 according to Figure 10 connected is. The projection 20 of the second end face 10.2 of the second retaining element 1.2 fits into the recess 19 (not shown here, see FIG. 9) of the first end face 10.1 of the first retaining element 1.1. The connection of the retaining elements 1.1, 1.2 takes place via the step-shaped end faces.

Figure 12 shows a first retaining element 1.1 with a projection 20 in a longitudinal section perpendicular to the height extension 6. The first end face 10.1 comprises two adjacent areas 11.1 and 11.2. Here, the second area 11.2 has an angle 12 with respect to the longitudinal extension 9, which is specifically about 15 degrees. The first area 11.1, compared to the second area 11.2, has a different angle with respect to the longitudinal extension 9. The angle of the first region 11.1 is approximately 90 degrees with respect to the longitudinal extension 9.

Figure 13 shows a second retaining element 1.2 in a longitudinal section perpendicular to the height extension 6, which has a second area 11.2 with a recess 19 at the second end 17.2.

Figure 14 shows a restraint system 2 in a longitudinal section perpendicular to the vertical extension 6 with the first restraint element 1.1 from Figure 12 and the second retaining element 1.2 Figure 13 . The retaining elements 1.1, 1.2 are joined together in an interlocking manner via their end faces.

Figure 15 shows a restraint system 2 in a longitudinal section perpendicular to the transverse extent 3, in which the first restraint element 1.1 has several recesses 19 (not shown here, see FIG Figure 9 ) and the second retaining element 1.2 has a plurality of projections 20. The projections 20 or the recesses 19 are parallel to the direction of a normal vector 21 of the end face 10 in the area 11.

The end faces 10.1 and 10.2 are designed to be complementary to one another and engage one another via the numerous projections 20 and recesses 19; they can thus be joined together in a form-fitting manner and can also be detached from one another again without being destroyed.

Figure 16 FIG. 3 shows an alternative embodiment of the restraint system 2 from FIG Figure 15 , in which the numerous projections 20 and recesses 19 (not shown here, see Figure 9 ) are oriented parallel to the direction of the vertical extension 6 and correspondingly different from the direction of a normal vector 21 of the end face 10 in the area 11.

Figure 17 shows a restraint system 2 in longitudinal section perpendicular to the height extension 6 with several projections 20 and recesses 19 (not shown here, see Figure 9 ). One side 22.1 is oriented parallel to the transverse extension 3 and perpendicular to the longitudinal extension 9, whereas the other side 22.2 has an angle 12 other than 90 degrees with respect to the longitudinal extension 9.

The Figures 18a to 18f show, each in cross section perpendicular to the longitudinal extension 9, retaining elements 1 with differently designed impact surfaces 14.

The retaining element 1 in Figure 18a has a flat impact surface 14, perpendicular to the transverse extension 3.

The retaining element 1 in Figure 18b comprises an inclined impact surface 14, which has an angle 12 not equal to 90 degrees with respect to the transverse extension 3.

The retaining element 1 in Figure 18c comprises a flat impact surface 14 and a base body 4 which is arranged on or on a base plate 7. In this case, the details of height 5 and width 13 relate only to the base body 4 and not the combination of base plate 7 and base body 4. The width 13 here is dependent on the height 5.

The retaining element 1 in Figure 18d comprises an impact surface 14 which, in a lower section 14.1 facing or facing the substrate 8, has an angle 12 greater than 0 degrees and less than 90 degrees relative to the transverse extent 3. The angle 12 is, in particular, approximately 30 degrees. In an upper section 14. 2 opposite the substrate 8, the impact surface 14 is oriented perpendicular to the transverse extension 3. The height 5 and the width 13 relate to the complete base body 4, the lower section 14.1 is part of the impact surface 14 and therefore not to be understood as a base plate 7. Here too, the width 13 is dependent on the height 5 and is smaller in the upper section 14.2 than in the lower section 14.1.

Figure 18e shows a retaining element 1 with an impact surface 14 which, in the lower section 14.1, has an angle 12.1 and the upper section 14.2 has a different angle 12.2 - each related to the transverse extension 3. In this exemplary embodiment, a height 5.1 of the upper section 14.2 is greater than a height 5.2 of the lower section 14.1.

Figure 18f shows a retaining element 1 according to the "New Jersey type" with a corresponding cross section.

Figure 19 shows a restraint system 2 with two restraint elements 1.1, 1.2 in a side view with a view of the impact surface 14, which restraint elements 1.1, 1.2 engage one another with a tongue and groove connection 23. A tongue, which is a type of projection 20, is inserted into a groove, which is a type of recess 19, in order to form the tongue and connection 23. The two retaining elements 1.1 and 1.2 are connected to one another via an additional connecting means 24. The connecting means 24 is attached to an upper side of the first retaining element 1.1 opposite the base plate 7. The arrangement and configuration of the connecting means 24 in this and the following figures is only to be understood as an example and not in a limiting manner. A horizontal arrangement of the connecting means 24, for example a screw connection, in the direction of the longitudinal extension 9 is also possible.

Through this tongue and groove connection 23, the two retaining elements 1.1 and 1.2 can be inserted or inserted into one another in a form-fitting manner and can also be detached from one another again without being destroyed. The connecting means 24 connects the first end 17.1 of the first retaining element 1.1 in the area of the end face 10 (not shown here, see FIG Figure 1 ) with the second end 17.2 of the second retaining element 1.2. The tongue and groove connection 23 of the interlocking end faces 10.1, 10.2 (not shown here, see Figure 1 ) is thus secured by an additional connecting means 24. The connecting means 24 can preferably and without restriction be a screw, a pin or a (screw) bolt, which enables the connecting means 24 to be removed without being destroyed, whereby the retaining elements 1.1 and 1.2 can be detached from one another without being destroyed.

Figure 20 shows the restraint system 2 Figure 19 in a top view. The section DD is in Figure 21 shown. The base plate 7 projects along the transverse extension 3 over the width 13 (not shown here, see FIG Figure 7 ) of the base body 4 (not shown here, see Figure 5 ) and can therefore be seen in the top view.

Figure 21 shows the section DD Figure 20 , which is oriented perpendicular to the longitudinal extension 9.

Figure 22 shows a restraint system 2 in a longitudinal section perpendicular to the transverse extension 3, in which the adjoining end faces 10.1 and 10.2 define a free space 25. The free space 25 is here a cuboid free space 25, which is arranged on an upper side of the retaining elements 1.1, 1.2 opposite the base plate 7. Within the free space 25, the adjoining end faces 10.1 and 10.2 do not touch.

A connecting element 26, in particular and without restriction made of metal (steel), is inserted into the free space 25. The connecting element 26 accordingly has a shape and dimensions that can be inserted into the free space 25 and is used to connect the retaining elements 1.1 and 1.2 via their end faces 10.1 and 10.2, respectively. Inserting the connecting element 26 into the free space 25 creates an (indirect) full-surface connection of the adjoining end faces 10.1 and 10.2 via the connecting element 26. The connecting element 26 can also be connected to or attached to the end faces 10.1 and 10.2 via connecting means 24. In Figure 22 the connecting means 24 are attached to an upper side of the retaining elements 1.1, 1.2 opposite the base plate 7.

Figure 23 shows a restraint system 2 in which the cuboid free space 25 is attached to an underside of the restraint elements 1.1, 1.2 facing the base plate 7.

In the free space 25 is according to Figure 23 a cuboid connecting element 26 inserts positively and accurately. The cuboid connecting element 26 is fastened to the base plate 7 via connecting means 24. In addition, the adjoining end faces 10.1, 10.2 can also be fastened or connected to one another via a connecting means 24 in an area in which no free space 25 is defined (shown here on the upper side of the retaining elements 1.1, 1.2).

Figure 24 shows a restraint system 2 in a longitudinal section perpendicular to the transverse extent 3, in which the adjoining end faces 10.1 and 10.2 of the restraint elements 1.1 and 1.2 form a prism-shaped free space 25 define. The tip of the prism-shaped free space 25 points towards the base plate 7.

A correspondingly shaped, prism-shaped connecting element 26 is inserted into the free space 25. In addition, connecting means 24 are attached to an upper side of the retaining elements 1.1, 1.2 opposite the base plate 7. The connecting means 24 connect the respective end faces 10.1, 10.2 to the connecting element 26 and correspondingly the retaining elements 1.1 and 1.2 to one another.

Figure 24 shows a restraint system 2 with a prism-shaped free space 25, which has a tip on a side facing away from the base plate 7 (in Figure 27 above).

In the area of the tip of a prism-shaped connecting element 26 inserted into the free space 25, a connecting means 24 is attached which connects the two end faces 10.1 and 10.2 to the connecting element 26 and also to one another.

Figure 26 shows a restraint system 2 in a longitudinal section perpendicular to the vertical extension 6 with a prismatic free space 25.

A prism-shaped connecting element 26 is inserted into the prismatic free space 25 in a form-fitting manner. The connecting element 26 can be connected to the end faces 10.1 and 10.2 via a plurality of connecting means 24 shown as an example. As in the aforementioned cases, this connection creates a more stable, but nevertheless releasable connection between two retaining elements 1.1 and 1.2.

It is also within the scope of the invention to provide retaining elements 1.1 and 1.2 which define a free space between them which - unlike at least implicitly described above - occupies only part of the width of retaining elements 1.1 and 1.2, but extends over their entire height ( or part thereof).

Figure 27 FIG. 2 shows a restraint system 2 with a horizontal connection section 27 and an inclined connection section 28. The horizontal connection section 27 is in the example of FIG Figure 27 arranged on a top side of the base body 4 opposite the base 8. The inclined connecting section 28 is arranged in the area 11.

Both in the horizontal connection section 27 and in the inclined connection section 28, the end faces 10.1, 10.2 of the retaining elements 1.1, 1.2 engage one another by means of a tongue and groove connection. Such a configuration of the restraint system 2 provides additional stability against impacting vehicles. Here, the horizontal connecting section 27 serves as an extended transition between the two retaining elements 1.1, 1.2.

Figure 28a shows a side view of the first end face 10.1 in the horizontal connecting section 27 of the first retaining element 1.1 from Figure 27 .

Figure 28b FIG. 11 shows an alternative side view of the horizontal connecting section 27 of the first retaining element 1.1 from FIG Figure 27 and Figure 28a . The groove is formed by a recess 19.

Figure 29a shows a side view of the second end face 10.2 in the horizontal connecting section 27 of the second retaining element 1.2 from Figure 27 .

Figure 29b FIG. 12 shows an alternative side view of the horizontal connecting section 27 of the second retaining element 1.2 from FIG Figure 27 and Figure 29a . The spring of the second end face 10.2 is formed by a projection 20.

As mentioned above, the first end face 10.1 (not shown here, see Figure 28b ) and the second end face 10.2 in the horizontal connecting section 27 designed to engage with one another with a tongue and groove connection.

Figure 30a shows a side view of the inclined connecting section 28 of the first retaining element 1.1 from Figure 27 .

Figure 30b shows a side view of the inclined connecting section 28 of the second retaining element 1.2 from Figure 27 .

As mentioned above, the first end face 10.1 (not shown here, see Figure 30a ) and the second end face 10.2 also designed in the inclined connecting section 28 to engage in one another while forming a tongue and groove connection. For this purpose, the tongue (projection 20) of the second end face 10.2 is inserted into the groove (recess 19) of the first end face 10.1 (not shown here, see FIG Figure 30a ) inserted.

Figure 31a shows a further development of the first retaining element 1.1 in the horizontal connecting section 27 with an additional spring 29.

Figure 31b shows a development of the second retaining element 1.2 in the horizontal connecting section 27 with an additional groove 30. The additional tongue 29 (not shown here, see FIG Figure 31a ) can be inserted positively into the additional groove 30. By engaging the additional tongue 29 in the additional groove 30, a double tongue and groove connection results. This increases the stability against side loads.

Figures 32a and 32b show the in Figures 31a and 31b Described further development of the retaining elements 1.1, 1.2 in the inclined connecting section 28. The retaining elements 1.1, 1.2 can also be connected in the inclined connecting section 28 with the aforementioned double tongue and groove connection.

Figure 33a shows the retaining elements 1.1 and 1.2 Figure 31a or 31b in a perspective with a view of the end faces.

Figure 33b shows a development of the retaining elements 1.1, 1.2 in the inclined connecting section 28, the additional spring 29 of the first retaining element 1.1 having an opening 31 on one side. A cuboid connecting element of the aforementioned type can be introduced through the opening 31 on one side. The additional tongue 29 with the opening 31 on one side can also be used as a groove, since a projection can be inserted into the opening. In this way, multiple tongue and groove connections can be formed.
