Description

[0016] Below, the invention is represented in reference to three embodiment examples and explained in further detail in reference to the drawings. The drawings show:

[0017] FIG. 1 a top view of a separation net according to the invention,

[0018] FIG. 2 a top view of another separation net,

[0019] FIG. 3 a top view of a third separation net.

[0020] The same reference numerals have been used for all the embodiments, even if the designs differ.

[0021] The separation net 10 shown in FIG. 1 comprises a net-like, tear-resistant rectangular textile web 11 formed of textile threads 12. Here, the web is a warp-knitted fabric in which the textile threads 12 form roughly square mesh openings.

[0022] For the creation of the desired peripheral contour, the textile web 11 was cut from a web of an already sized warp-knitted fabric, as a result of which, on the lateral, straight outer edges 16, 17, loose ends 13 were created on the textile threads 12 by the separating cut. The outer edges 16, 17 can also have any curved shape due to a corresponding separating cut. However, the loose ends 13 on the textile threads 12 are securely bound, namely by the plastic material of a single-layered edge strip 18, in which the ends 13 of the textile threads 12 are embedded. This lateral edge strip 18 produces a single-layered firmly bonded connection between the plastic material and the textile threads 12, without the strength of the textile web 11 being influenced. The loose ends 13 of the textile threads 12 are held securely in the plastic. Tearing out of the textile threads 12 is prevented by this finely bonded connection with the plastic material of the single-layered edge strip 18. In this example, PES/PA textile threads 12 were used.

[0023] FIG. 2 shows an additional embodiment of a separation net 10. This separation net 10 comprises a net-like, trapezoidal textile web 11, which also consists of a warp-knitted fabric. However, in this warp-knitted fabric, rhomboid mesh openings are provided. The trapezoidal peripheral contour was produced from the original warp-knitted fabric by a separating cut, namely on the side edges 16, 17 and on the upper outer edge 14. These cut edges are subsequently bound by a single-layered edge strip 18, and thereby the loose ends 13 of the textile threads 12 of the textile web 11 that were created by the cutting to size on the side edges 16, 17 and the upper outer edge 14 are embedded, firmly bonded, in the plastic material of the single-layered edge strip 18.

[0024] FIG. 3 shows an additional embodiment example. The separation net 10 according to the invention has a net-like textile web 11 with a peripheral contour that is adapted to the shape of the vehicle interior of a motor vehicle, so that the opening area between the vehicle walls and the separation net is reduced to a minimum, which ensures a good partitioning of the interior spaces. Depending on the design of the motor vehicle and the resulting different shape of the side walls and of the roof of the motor vehicle, fitting separation nets can be provided, which optionally also have recesses in course of the edge thereof. The textile web 11 in this case is a fabric. On all four outer edges 14, 15, 16, 17, a single-layered peripheral edge strip 18 made of plastic material is provided, which is connected, firmly bonded, to the textile threads 12 of the textile web.

[0025] The embodiments of a separation net 10 shown in the drawings are just a few examples for a separation net according to the invention. The invention is not limited to these embodiments. In addition to a net-like textile web 11 with square or rhomboid mesh openings, rectangular, honeycombed or other mesh openings are also possible. It is essential that the loose ends of the textile threads 12 that are created by a cutting of the textile web 11 to any shape are bound securely at the edges. The mesh openings of the textile web 11 can here be of equal or different size. In addition, the textile threads 12 of the textile web 11 can be designed to be uniformly black, white or also colored. In addition, in a known manner, the textile web can be provided with an appropriate sizing, depending on the application case, for example, with a flame-retardant coating or with a coating for solidifying the textile threads 12.

[0026] The separation nets 10 shown in the examples can be provided, in a known way, with fastening elements, for example, in the form of a hook, an eyelet or another form. On the upper outer edge 14, fastening elements can be provided for connecting to a metal holding rod and, on the lower outer edge 15, fastening elements can be provided for connecting to the winding shaft. Such fastening elements can also be formed directly integrally with the edge strips 18. On a lower outer edge 15, the edge strips 18 can be formed, for example, in the shape of a piping which can be pulled into a groove of the winding shaft.
