Definitions

  • the invention relates to a roller blind for a roller blind arrangement of a motor vehicle, comprising the features of the preamble of patent claim 1, as well as a roller blind arrangement with such a roller blind.
  • roller blind is known from practice and is used in a roller blind arrangement as an adjustable shading element which can be used, for example, in the area of a transparent vehicle roof section.
  • the roller blind is adjustable between an open position wound into a roller blind and an unwound closed or shading position.
  • the roller blind arrangement can have lateral guide rails in relation to the vertical longitudinal central plane of the roof, in each of which an edge of the roller blind is guided.
  • the roller blind has a central section which forms a visible surface in the unwound state or in the closed position of the roller blind and a guide strip made of textile material is attached to each of its lateral edges, which engages in a corresponding guide path of the guide rail in question and which has a friction partner opposite the relevant guide rail, in particular made as an extruded aluminum profile, which has an anodized surface.
  • a guide band can be connected to each of the guide strips, which holds the roller blind in the relevant guide rail and which is designed, for example, as a scroll spring that causes the roller blind to be wound up outside the guide rail to form the roller blind.
  • the textile material of the guide strips is each formed from a fabric that has a plain weave made from so-called warp threads and so-called weft threads.
  • the plain weave results in an almost full contact of the guide strip in the relevant areas of the guide rail.
  • the warp threads and the weft threads are each equipped with a flame-retardant material.
  • the fabric made from the warp and weft threads is provided with a finish made from a flame-retardant material, which is applied using an immersion bath process or a padding process.
  • the previously used flame-retardant substance can impair the tribological behavior of the roller blind in the guide rails.
  • the invention is based on the object of creating a roller blind with guide strips, the tribological behavior of which is optimized with respect to the guide rails, and a roller blind arrangement with such a roller blind.
  • a roller blind for a roller blind arrangement of a motor vehicle comprising a central section, which forms the visible surface of the roller blind in the unwound state, and lateral guide strips that are each connected to a lateral edge of the central section and each for guiding the Roller blinds serve in a respective guide rail and each comprise a fabric with a plain weave, which is formed from warp threads and weft threads, the weft threads alternately overlapping at least two adjacent warp threads at right angles to the warp direction and then reaching under at least one warp thread.
  • the weaving pattern according to the invention in which the weft threads cross the warp threads running at right angles to this, in a way different from the conventional plain weave, that alternately at least two successive warp threads are overlapped and then at least one warp thread is overlapped, resulting in a macroscopic diamond-like or honeycomb-like structure, so that the Guide strip rests only selectively in the relevant guide rail, which leads to optimized tribological properties of the guide strips in the guide rails.
  • Such Structure can be implemented in particular by using a so-called jacquard loom.
  • a weaving pattern is implemented in which adjacent weft threads overlap and overlap the warp threads in opposite directions.
  • the warp threads that are overlapped by a specific weft thread are overlapped by at least one of the adjacent weft threads
  • the warp threads that are overlapped by a specific weft thread are overlapped by at least one of the adjacent weft threads.
  • the weft threads each have a course such that they alternately overlap two adjacent warp threads at right angles to the warp direction and then reach under two further adjacent warp threads.
  • Adjacent weft threads which follow one another in the warp direction, each run in the opposite direction, that is, one first engages under two adjacent warp threads and then engages over two further adjacent warp threads and the other first engages over the first two adjacent warp threads and then engages under the two further adjacent warp threads .
  • the weave pattern can be designed in such a way that at least two adjacent weft threads or weft threads that follow one another in the warp direction reach over and under the warp threads in the same direction.
  • the fabric is preferably provided with a flame retardant based on an alkyl phosphonate compound.
  • a flame retardant based on an alkyl phosphonate compound for example, the connection sold under the name APYROL PES can be used for this purpose.
  • the weft threads and the warp threads are each additionally provided with a flame-retardant material before the fabric is produced.
  • the invention also relates to a roller blind for a roller blind arrangement of a motor vehicle, comprising a central section which in the angled state of the Roller blind forms the visible surfaces, and lateral guide strips, which are each connected to a lateral edge of the central section and each serve to guide the roller blind in a respective guide rail and each comprise a fabric with a plain weave, which is formed from warp threads and weft threads, the fabric is provided with a flame retardant based on an alkyl phosphonate compound.
  • the alkyl phosphonate compound is, for example, the compound sold under the name APYROL PES.
  • This flame retardant only needs to be applied to the fabric in a small amount in order to meet the legal requirements. This in turn leads to an improvement in the tribological behavior of the guide strips in the guide rails, which as a rule each consist of an extruded aluminum profile and which can each have an anodized surface.
  • the small amount of flame retardant applied to the fabric also improves the reproducibility of the properties of the guide strips.
  • the expenses for fine tuning are reduced compared to the prior art, which in turn ensures high series quality.
  • due to the good tribological behavior of the guide strips in the guide rails a large extension length for the roller blind can be achieved without the function of the roller blind arrangement in question being impaired.
  • the fabric designed according to the invention can be used for guide strips of roller blinds which have a conventional two-dimensional woven structure.
  • the fabric can also have a three-dimensional woven structure, which is implemented, for example, in a guide strip fabric with a cross-section that is T-shaped in the broadest sense.
  • the invention also relates to a roller blind arrangement for a motor vehicle which comprises a roller blind of the type described above and two lateral guide rails, in each of which one of the lateral guide strips of the roller blind is guided.
  • A.sungsbei game of a roller blind according to the invention is shown schematically simplified in the drawing and is explained in more detail in the following description. It shows:
  • Figure 1 is a schematic plan view of a vehicle roof with a roller blind arrangement according to the invention
  • Figure 2 shows a section through the roller blind arrangement in the area of a lateral
  • FIG. 3 shows a microscopic representation of a fabric of a lateral guide strip of a roller blind of the roller blind arrangement.
  • a vehicle roof 10 of an otherwise not shown passenger car is shown, which has a roof opening 12 which can be closed or at least partially released by means of a transparent cover element 14 made of glass.
  • the vehicle roof 10 has a shading device which is formed by a roller blind arrangement 16.
  • the shade assembly 16 includes a
  • Roller blind 18 which can be wound up in the region of a rear edge of the roof opening 12 on a winding shaft 20 to form a roller blind.
  • the roller blind 20 On its edge facing away from the winding shaft 20 and extending in the transverse direction of the roof, the roller blind 20 is provided with a tension bow 22 which serves as an actuating element of the roller blind 18.
  • the roller blind 20 comprises a central section 24 which, in the unwound state of the roller blind 18, forms a visible surface that is visible from the vehicle interior.
  • the roller blind 18 is guided at its lateral edges in a respective roof-mounted guide rail 34A or 34B of the roller blind arrangement 16.
  • the fabric 30 of the guide strips 28 each has a plain weave, which is formed from warp threads 36 and weft threads 38 running at right angles thereto.
  • the fabric 30 has a weaving pattern in which the weft threads alternately or alternately initially overlap two consecutive warp threads 36 and then engage under two consecutive warp threads 36, and then again two consecutive warp threads 36 to reach over and then to reach under two adjacent warp threads 36, whereas the weft threads 38 adjacent in warp direction X each show an opposite direction, that is, each first reach under two adjacent warp threads 36 and then reach over two adjacent warp threads 36, and then again two adjacent warp threads 36 to reach under and to reach over two adjacent warp threads 36.
  • the next weft thread 38 in warp direction X again has a course in the same direction as the course of the weft thread 38 described first.
  • this weave structure enables a diamond-like or honeycomb-like structure to be realized in the broadest sense, which overhangs guide rails 34A and 34B the surface forms distributed punctual support areas.
  • the fabric 30 of the guide strips 28 is each provided with a flame retardant which is based on an alkylphosphonate compound and which is applied using a padding process.
  • the alkyl phosphonate compound is the compound sold under the name APYROL PES.
  • the fabric 30 has a material thickness of approximately 0.3 mm and can be manufactured in a so-called jacquard weaving machine using a 2D or 3D process. List of reference symbols
