Description

[0001] The invention relates to a partition net device for a motor vehicle, with a tension band fixation comprising a pipe element and a tension band with an end loop which is guided in a band area around the pipe element, according to claim 1. Furthermore, the invention relates to a corresponding method for providing a partition net device for a motor vehicle and a motor vehicle according to claims 9 and 10.

[0002] Cargo nets are used in motor vehicles, for example, to separate the trunk from the passenger compartment as needed. These nets are usually rollable, similar to a Venetian blind, and can be secured in the operating position using tension straps or belts attached to appropriate fixtures such as eyelets and hooks. A particularly robust and easy-to-install connection between the at least one tension strap and the cargo net is advantageous.

[0003] EP 2 922 733 B1 discloses a protective device for a compartment of a motor vehicle, comprising a flexible surface structure movable between a compactly stowed storage position and at least one functionally extended position, which is provided with a dimensionally stable extension profile at its front end in the extension direction. This is a relatively complex design compared to a tension band.

[0004] Alternatively, a design is known in the prior art in which the tension band is riveted over a pipe of the partition net by means of a bridge; however, this requires machining and may necessitate a sharp-edged bridge. Alternatively, a protrusion of the lower pipe is embossed with a bridge, which is then fixed and riveted. However, this requires a particularly high amount of material and additional tools for assembly and also favors a sharp-edged design of the bridge.

[0005] Furthermore, in the prior art, riveting is carried out from the outside in, whereby a predefined assembly sequence is specified during production and a cross-section of the pipe must be drilled. In this process, the rivet is applied to a visible surface, and machining is also necessary. With this method, the direction of pull on the rivet can also lead to loosening of the riveted joint.

[0006] The object of the present invention is to provide a tension band fixing of a partition net device, a method for providing the partition net device and a corresponding motor vehicle, which enables a particularly advantageous design of the partition net device without, for example, machining assembly and / or a complicated construction using extension profiles, while simultaneously requiring particularly low manufacturing effort.

[0007] This problem is solved according to the invention by the subject matter of the independent claims.

[0008] A first aspect of the invention relates to a partition net device for a motor vehicle with a tension band fixation, comprising a tubular element and a tension band with an end loop which is guided around the tubular element in a band area, wherein the band area is bounded at one end by a proximal ring element which surrounds the tubular element, and a plug element is attached to an end area of ​​the tubular element which bounds the band area at the other end and has an internal geometry which is introduced into the tubular element and embossed with it for fixation and the outer circumference of the plug element is larger than that of the tubular element in the band area, and the band area is spanned by a bridge element, in particular such that the tension band is projected over by the bridge or the bridge element, which is given by the end loop.

[0009] The motor vehicle is, in particular, a passenger car, truck, and / or bus. The tubular element is, in particular, a tubular boundary element of a partition net of the net system and is specifically arranged on it. The tensioning strap is, for example, made of a fabric similar to a seatbelt. The end loop is formed, in particular, by the tensioning strap itself and is created, for example, by the tensioning strap being laid in a loop and sewn accordingly. The tensioning strap fixing or the tensioning strap is, in particular, arranged at one end of the tubular element, such that the ring element, which can essentially be formed from a ring, whose inner diameter is so close to the outer diameter of the tubular element that they can be assembled together in a fit-fit manner.Proximal here means that the ring element is arranged along the longitudinal direction of the pipe element on the side of the band section opposite the end or end region of the pipe element. The ring element essentially forms a ring geometry on the pipe element, which is specifically designed to prevent the tension band from slipping proximally or inwards along the pipe element.

[0010] The plug element has an inner geometry that is inserted into the end of the tube. Furthermore, the plug element has a second geometry that, similar to a ring element, rests against the tube element on its outer circumference. The inner geometry is positioned with its outer diameter against an inner diameter of the tube element, allowing for a favorable and, in particular, simple embossing between the tube element and the inner geometry of the plug element. This embossed area connects the plug element to the tube and thus secures the tension band within the band area. Due to the outer circumference or geometry of the plug element, slippage of the tension band is prevented, similar to a ring geometry, but now in the distal direction towards the end of the tube or the end of the tube element.The bridge or bridge element serves, in particular, to prevent the tension band from leaving the band area, for example, in the event of excessive tensile stress transverse to the actual tension band tension or essentially along the longitudinal direction of the pipe element. Furthermore, the bridge element, especially in the operating position of the separation net device, is arranged on the pipe element in such a way that the end loop of the tension band, which is particularly freely movable, can advantageously align itself along the direction of the force.

[0011] In other words, a tension band fixation is shown, which has an outer geometry and an inner geometry, with an embossed area provided to connect a corresponding plug element of the tension band fixation to the pipe. Furthermore, the ring geometry of the tension band fixation prevents the tension band from slipping on the pipe.

[0012] The partition net device according to the invention offers several advantages over the prior art: it simplifies and / or accelerates the manufacturing process, potentially resulting in significantly lower costs. Furthermore, it allows for the standardization of multiple projects, enabling the tension band fixation or partition net device to be used advantageously for several vehicle models, for example. In addition, a particularly advantageous application is possible, for instance, due to the possibility that the tension band aligns itself along the force direction.

[0013] In an advantageous embodiment of the invention, the bridge element is connected to and / or formed on the plug element, and / or the bridge element is connected to and / or formed on the ring element. In other words, the bridge element is arranged on the plug element and / or the ring element such that the plug element or the ring element transitions into the bridge element, or the bridge, in particular, projects from the respective outer circumference in such a way that it spans the band area. Additionally or alternatively, the bridge element and the plug element, or the ring element and the plug element, are formed together, in particular as a single piece, and thus each are manufactured as one part and / or from the same material. This offers the advantage that the bridge element can be used particularly advantageously for guiding the tension band.Furthermore, the advantage is that the separation net device can be designed with very few components and can therefore be provided particularly easily, for example.

[0014] In a further advantageous embodiment of the invention, the bridge element, the plug element, and / or the ring element are made of or formed from a plastic. In other words, the main material underlying the bridge element, the plug element, and / or the ring element is a plastic, which may also include composite materials. For example, the plastic bridge and the side cover or plug, i.e., the plug element, can be advantageously integrated together. Furthermore, this offers a particularly advantageous embodiment, especially compared to the prior art, where the bridge is typically made of a potentially sharp-edged sheet metal.

[0015] In a further advantageous embodiment of the invention, the inner diameter of the end loop or band loop is less than or equal to the outer diameter of the ring element and / or the outer circumference or outer diameter of the plug element. In other words, the clearance of the tension band loop, which is inserted into the band area via the tube element, is smaller than that of the elements enclosing the band area, namely the ring element or the plug element. This offers the advantage that the loop cannot leave the band area, regardless of the design of the bridge element.

[0016] In a further advantageous embodiment of the invention, the length of the band area is greater than or equal to the width of the tensioning band. In other words, the band area, along the longitudinal direction of the pipe element, has a length at least equal to the width of the tensioning band. Having at least the same width is advantageous so that the tensioning band can lie flat within the band area, for example, without creases forming when the tensioning band is installed. Furthermore, a width smaller than the length of the band area offers the advantage of easily allowing the tensioning band to be loosely mounted, which, for example, makes it particularly advantageous for the tensioning band to align itself along a force direction.

[0017] In a further advantageous embodiment, a partition net is formed which is bounded by and / or connected to the pipe element at at least one of its edges. In other words, the partition net assembly comprises a partition net which, for example, includes meshes of a specific size, determined by a fiber arrangement, with the pipe element being arranged at least at one edge of the partition net. The partition net can also be very fine-meshed or without holes, or with a hole size comparable to a fine-mesh fabric. In the operating position, the edge is oriented, in particular, in the transverse direction of the vehicle and is located, especially in the operating position of the partition net or partition net assembly, at the bottom along the vehicle's vertical direction.This offers the advantage that the pipe element, and thus the tension band fixation, can be provided particularly advantageously with the separation net for the separation net device.

[0018] In a further advantageous embodiment of the invention, the connection between the pipe element and the partition net is formed by a tunnel element of the partition net into which the pipe element is inserted. Furthermore, the tunnel element particularly has a recess for the tensioning strap. In other words, a tunnel element is provided which is essentially formed as a loop along the edge of the net on which the pipe element is oriented, and which has an inner diameter that is at least larger than the outer diameter of the pipe element, and in particular at least partially larger than the outer diameter of the plug element and / or ring element, so that the pipe element can be inserted into the tunnel element for the purpose of assembling the partition net assembly.This offers the advantage that a particularly advantageous and especially flexible connection can be formed, which can be easily formed, especially during the manufacturing or provision of the separating net device.

[0019] In a further advantageous embodiment of the invention, at least two tension bands are arranged on the tubular element and / or the bridge element is arranged on a side of the tubular element on which the partition net is oriented. In other words, the partition net assembly comprises two tension band fixings, or the partition net is fixed in its operating position by means of two tension bands. Additionally or alternatively, the bridge element is arranged on the side on which the partition net is attached to the tubular element. Thus, in a typical operating position in a motor vehicle, the bridge element is oriented on the tubular element, in particular, substantially along the vehicle's vertical axis.Since the tensioning strap is usually arranged on the side of the pipe element opposite the partition net, in order to enable, for example, particularly effective tensioning of the partition net in the operating position, it follows that the bridge is not visible on an outside or a visible surface of the partition net device.

[0020] A second aspect of the invention relates to a method for providing a partition net device for a motor vehicle, which comprises a tension band fixation, a pipe element and a tension band with an end loop, a ring element and a plug element.

[0021] In particular, the separation net device which is provided by means of the method according to the second aspect of the invention is a separation net device according to the first aspect of the invention or an analogously constructed separation net device.

[0022] The inventive method for providing the separation net device comprises the following steps: In the first step, the ring element is slid onto the pipe element, thus defining a band area proximally. In the second step, the end loop is threaded onto the band area of ​​the pipe element. In the third step, the plug element is attached to one end of the pipe element, thus defining the band area at the other end and creating an internal geometry of the plug element within the pipe element. In the fourth step, the internal geometry is embossed onto the pipe element to fix the two in relation to each other.

[0023] In other words, the first step involves sliding a ring of a mounting plate onto the tube. The second step involves threading the tensioning strap loop through it. The third step involves pressing a plug into the tube, specifically until it stops, essentially along the transverse direction of the vehicle in its operating position. Finally, in the fourth step, the plug is pressed into the tube.

[0024] Advantageous embodiments and further developments, as well as advantages of the first aspect of the invention, are to be regarded as advantageous embodiments and further developments, as well as advantages of the second aspect of the invention, and vice versa.

[0025] A third aspect of the invention relates to a motor vehicle with a partition net device according to the first aspect of the invention or with a partition net device that is manufactured or provided by means of a method according to the second aspect of the invention.

[0026] Advantageous embodiments and further developments, as well as advantages of the first and second aspects, are to be regarded as advantageous embodiments and further developments, as well as advantages of the third aspect of the invention, and vice versa.

[0027] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations or on their own.

[0028] The invention will now be explained in more detail with reference to a preferred embodiment and the drawings. The drawings show: Fig. 1 a schematic perspective view of a partition net device with a partition net and a tension band fixation; Fig. 2 a schematic view of the tension band fixation according to Fig. 1; and Fig. 3 A schematic perspective view of a section of the tension band fixation in combination with the partition net.

[0029] Fig. Figure 1 shows a schematic perspective view of a cargo net device 1 for a motor vehicle, which is represented by the cargo net device 1. The cargo net device 1 comprises a tension band fixing 2, which has a tube element 3 and a tension band 4. Furthermore, the cargo net device 1 includes a cargo net 5, which can be attached to the headliner of the motor vehicle by means of a fastening element 6. The cargo net 5 of the cargo net device 1 can, for example, be rolled up like a roller blind and moved from the rolled-up position to a usable position by means of the straps 7.

[0030] In the operating position, for example, fixing elements 8 designed as hooks, which are attached to the tensioning straps 4, can be attached to a corresponding receptacle in order to fix the partition net device 1 in the operating position by means of the tensioning straps 4.

[0031] Fig. Figure 2 shows a section of the tension band fixation 2 of the partition net 5 or the partition net device 1, wherein the tension band 4 has an end loop 9 that is guided around the pipe element 3 in a band section 10. The band section 10 is bounded at one end by a proximal ring element 11 that encloses the pipe element 3. A plug element 13 is attached to an end section 12 of the pipe element 3 opposite the proximal ring element 11 in the band section 10, and this plug element 13 binds the band section 10 at the other end. The plug element 13 has an internal geometry 14 that is incorporated into the pipe element 3 and is embossed to it in at least one embossed area 15 for fixation. The outer circumference 16 of the plug element 13 is larger than that of the pipe element 3 in the band section 10, and the band section 10 is further spanned by a bridge element 17.The coordinate system 20 indicates the orientation of the partition net device 1 or the tension band fixation 2 in a suitable operating position in the motor vehicle.

[0032] Furthermore, a method for providing the separation net device 1 shown will be demonstrated, which comprises the following steps: In a first step, the ring element 11 is slid onto the pipe element 3, thereby proximally limiting the band area 10. In other words, a ring of a mounting plate is slid onto the pipe, thus forming a limit or fixing of the tension band.

[0033] In a second step, the end loop 9 is threaded onto the band area 10 of the pipe element 3, so that the end loop 9 or band loop is guided around the pipe element 3 in the band area 10.

[0034] In a third step, the plug element 13 is attached to the end region 12 of the tube element 3, thereby limiting the band area 10, with the internal geometry 14 of the plug element 13 being inserted into the tube element 3. For this purpose, the tube element 3 is hollow, at least in this region, and thus designed as a tube. Furthermore, in the third step, particularly along the y-direction or in the operating position in the transverse direction of the vehicle, the plug is pressed into the tube until it reaches its stop.

[0035] In a fourth step, the inner geometry 14 is embossed with the tube element 3, in particular in the embossing area 15 shown, to fix the plug element 13 to the tube element 3.

[0036] The motor vehicle presented using the partition net device 1 can therefore have a partition net device 1 which is designed according to the method presented here.

[0037] The partition net device 1 according to the figures comprises (at least) two tension bands 4, both of which are arranged on the pipe element 3. Additionally or alternatively, the bridge element 17 is arranged along the z-direction or in the vehicle's vertical direction at the top, and thus on a side of the pipe element 3, on which the partition net 5 is oriented, so that the bridge element 17 can be oriented in such a way that an impairment of a viewing area of ​​the partition net device 1 is excluded.

[0038] The separation grid 5 has a region, in particular a border, compare Fig.3, which is bounded by and in particular connected to the pipe element 3. The connection is formed by a tunnel element 18, which is essentially formed by a loop extending over the edge of the separating mesh 5. The pipe element 3 can be inserted into this loop or tunnel element 18, and a recess 19 can be provided in the tunnel element 18, in particular for the respective tension band 4, through which the tension band 4 is guided.

[0039] The bridge element 17 can be connected to or formed with the plug element 13. Additionally or alternatively, the bridge element 17 can be connected to or formed with the ring element 11. In particular, the bridge element 17 is designed such that it extends over the band area 10 as completely as possible in order to ensure a certain degree of guidance of the tension band 4.

[0040] Both the bridge element 17 and the plug element 13 and / or the ring element 11 can advantageously be made of a plastic or at least incorporate a plastic as a material component. This results in the advantage, for example, of a particularly lightweight and / or less sharp-edged design of the respective element.

[0041] Advantageously, the inner diameter of the end loop 9 is less than or equal to the outer diameter of the ring element 11 and / or the outer circumference 16 of the plug element 13. Furthermore, the length of the band section 10 is advantageously greater than or equal to the width of the tension band 4.

[0042] The partition net device 1 shown, the corresponding method for its provision, and the motor vehicle offer the following advantages: The bridge or bridge element 17 can be oriented on its upper side and thus in the z-direction, so that it is not visible on the surface. Furthermore, the bridge can be made of plastic, and the side cover or plug can advantageously be integrated with or into the bridge for easy assembly. In addition, corresponding tension band fixings 2 can be used for similar projects. Due to the embossing, particularly in the embossed area 15, additional fastening elements, such as rivets, between the plug element 13 and the pipe element 3 can be omitted. This can result in particularly low assembly costs.Furthermore, due to the machining-free provision of the separating mesh device 1, particularly compared to prior art, it is possible to minimize or even eliminate the risk of sharp edges on the pipe or pipe element 3 and / or the bridge element 17. This prevents damage to the tension band caused by its fixing, for example, due to sharp edges and / or rivets.

[0043] The belt area 10, the guidance provided by the bridge element 17, and the lateral limitation of the belt area 10 – the plug element 13 and the ring element 11 – allow for loose mounting or guidance of the tensioning belt 4, enabling it to align itself particularly advantageously along the direction of the force, for example along the z-direction.

[0044] Thus, a chipless assembly allows for damage-free fixing of the tension band 4 without the need for additional fastening and / or securing elements. Furthermore, this makes setup particularly easy. Advantageously, the sealing plug or plug element 13 can be conveniently integrated into the tube or tube element 3. This can, for example, simplify and / or accelerate the manufacturing process and thus the setup of the partition net device 1. Overall, an advantageous tension band fixing 2 for a partition net 5 is shown here. Reference symbol list 1.
