Definitions

  • the invention relates to an electrically heatable surface heating element with a fabric, which in a first direction and / or in a second direction extending filaments comprising electrically conductive fabric threads has.
  • the invention relates to an interior fitting for motor vehicles with such an electrically heatable surface heating element.
  • Electrically conductive textiles are used, for example, for heat generation and also for shielding electromagnetic radiation and for transmitting electrical signals, in particular sensor signals as well as telecommunication and data signals.
  • Electrically conductive threads may in this case be incorporated into a fabric, i. H. At least some fabric threads running in the warp direction and / or in the weft direction can be electrically conductive, so that, for example, electrical signals can be transmitted via these fabric threads.
  • electrically conductive fabric threads and non-conductive fabric threads can be used.
  • the electrically conductive fabric threads may protrude beyond an edge of the fabric and be connected in their protruding end portion to a connection cable via which they are connectable to the power source or electrical circuit. For this, however, it is necessary that the edge of the fabric is accessible for making the electrical connection.
  • Object of the present invention is to develop an electrically conductive textile of the type mentioned in such a way that the electrically conductive fabric threads are connected in a simpler manner to a power source or an electrical circuit.
  • electrically conductive connecting threads are still used, which are woven into the fabric only over a partial region of their length.
  • the connecting threads allow in a simple manner an electrical connection of the electrically conductive fabric threads with a power source, an electrical circuit, a sensor or other electrical component.
  • the connecting threads can be led out obliquely or vertically out of the area defined by the tissue and, for example, a connecting cable can be connected to the connecting threads.
  • the inventive design of the electrically conductive textile has the advantage that the edge region of the fabric does not have to be accessible for making electrical contact with the electrically conductive fabric threads.
  • the electrical connection of the tissue can rather be done within the tissue. For this it is only necessary in the desired connection area of the fabric to weave the electrically conductive connecting threads into the fabric by weaving technique.
  • the webtechnische integration of the connecting threads in the tissue has the additional advantage that the contact area between the connecting threads and the tissue does not form a significant mechanical reinforcement of the tissue, d. H. the contact area is haptically practically indeterminable. The contact area can not be easily felt. This is particularly advantageous when the fabric forms a coating for an interior fitting of a motor vehicle. It is then possible to supply power to the tissue via the connecting threads without the contact area between the connecting threads and the tissue being able to be felt by the vehicle user.
  • the connecting threads can be passed, for example, through an opening of a main body of the interior fitting part, which is to be coated on the visible side with the fabric. A frontal connection of the tissue to a power source can be omitted and yet the tissue can form a very uniform reference of the body.
  • the connecting threads form electrically conductive floating threads, which are partially incorporated into the fabric and form thread floats between their bound sections and are separated in the area of the thread floats.
  • the connecting threads in the form of electrically conductive floats can be partially loose over warp or weft threads of the fabric, where they are only partially integrated into the fabric and produce between the incorporated areas thread floats. After the floats are woven in regions, they can be separated in the area of the floats, so that they protrude with their ends from the tissue and thereby within the tissue a haptic not detectable Allow connection of the tissue to a power source, an electrical circuit or other electrical device.
  • the connecting threads extend in the weft direction in their part of the weave which is woven into the fabric. They can thus be integrated into the tissue at any point during the weaving process. This facilitates the packaging of the tissue.
  • the fabric has a leno weave with lower warp threads, are placed on the weft threads, and with binding warp threads which engage under the lower warp threads and which engage over the weft threads.
  • a leno weave has the advantage that the fabric can be made extremely resistant to shifting.
  • the heating filaments comprising electrically conductive fabric threads can be fixed in a structurally simple manner relative to one another and, in particular, be held at a distance from one another. There is therefore no risk that the electrically conductive fabric threads slip.
  • the weft threads are laid on so-called lower warp threads, which are also referred to as upright warp threads, and by binding warp threads, which are also referred to as upper warp threads or leno warp threads, the weft threads are fixed to the lower warp threads.
  • the binding warp threads engage under the lower warp threads and they spread over the weft threads.
  • a very slip-resistant fabric is produced, wherein the binding warp threads wrap around the lower warp threads and the weft threads.
  • the angle of wrap is considerably greater than in the case of woven fabrics of twill, twill or satin weave.
  • the fabric is stretchable, that is to say stretchable fabric threads, in particular stretchable, electrically conductive fabric threads, since this makes it possible to achieve three-dimensional shapes in a simple manner realize.
  • Such three-dimensional shapes can be used, for example, in interior components of vehicles.
  • the weft threads are pinched between the lower warp threads and the binding warp threads and thereby fixed.
  • At least some fabric threads of the fabric with leno weave are electrically conductive and can, for example, be heated electrically or serve to transmit electrical signals.
  • the electrically conductive connecting threads can be structurally integrated into the fabric having a leno weave. At least some of the connecting threads may run parallel to the weft threads in their weaving-in-tissue-bonded region and be overlapped by the binding warp threads. Alternatively or additionally, it can be provided that at least some connecting threads run parallel to lower warp threads and are held together with these by means of a binding warp thread on weft threads.
  • At least some electrically conductive fabric threads form weft threads of the fabric.
  • the fabric has first electrically conductive fabric threads running in the warp direction and second electrically conductive fabric threads extending in the weft direction.
  • the fabric has a leno weave.
  • the high slip resistance of the leno weave of the fabric ensures that the first electrically conductive fabric yarns are stable with the second electrically conductive fabric yarns are electrically connected.
  • the first and second electrically conductive fabric threads lie directly against each other.
  • first and the second electrically conductive fabric threads In order to ensure an electrical connection between the first and the second electrically conductive fabric threads, therefore, it is not absolutely necessary to use an additional electrically conductive contact element; in particular, it is not necessary for the first and second electrically conductive fabric threads to be electrically and / or mechanically connected to one another by means of an additional sewing thread connect to.
  • the electrically heatableêtnheizelement can thus be completed by ensuring the electrical contact between the first and second conductive fabric threads alone by the weaving process without an additional step to ensure the electrical contact between the conductive fabric threads is required.
  • It may be provided in a fabric with leno weave that form both the lower warp threads and the binder warp threads extending in the warp direction electrically conductive fabric threads.
  • the upper side of the fabric having a leno weave is dominated in appearance by the weft yarns laid on the lower warp yarns. This is especially the case when the binder warp threads are translucent. They are therefore difficult to see by the naked eye. They can be translucent or transparent.
  • electrically conductive fabric threads may have a different length-specific electrical resistance than extending in the weft direction electrically conductive fabric threads.
  • electrically conductive fabric threads running in the warp direction have a shorter length-specific electrical resistance than the electrically conductive fabric threads running in the weft direction.
  • all fabric threads running in the first direction or in the second direction are electrically conductive.
  • the fabric has in addition to electrically conductive fabric threads in the first direction and / or in the second direction extending electrically non-conductive fabric threads.
  • the electrically non-conductive fabric threads can form, for example, lower warp threads and / or binder warp threads which run in the warp direction and in addition to running in the warp direction electrically conductive fabric threads are used.
  • the electrically non-conductive fabric threads can also form weft threads of the fabric.
  • one or more electrically non-conductive fabric threads are used as weft threads.
  • no electrically non-conductive fabric threads are arranged in at least one region of the fabric between at least two electrically conductive fabric threads extending in the weft direction.
  • One or more electrically non-conductive fabric threads may adjoin the at least two electrically conductive fabric threads.
  • a plurality of electrically conductive fabric threads run in the warp direction and are arranged directly next to one another and that one or more electrically non-conductive fabric threads adjoin this plurality of electrically conductive fabric threads.
  • the electrically conductive textile forms an electrically heatable surface heating element with designed as heating filaments electrically conductive fabric threads, which are integrated via the connecting threads in an electrical circuit.
  • the heating filaments can thus be supplied with electrical current via the connecting filaments.
  • the length-specific electrical resistance of the connecting threads can be considerably less than the length-specific electrical resistance of the heating filaments.
  • the filaments extend in the weft direction of the fabric.
  • the filaments can be set in a simple manner during the weaving process at a distance from each other at the lower warp and binding warp threads. It is therefore not mandatory to arrange between the filaments in the weft direction extending electrically non-conductive fabric threads.
  • electrically non-conductive fabric threads can be used in addition, wherein they are preferably thermally conductive, so that the heat energy provided by the heating filaments can be distributed evenly over the tissue.
  • the fabric has a leno weave, wherein the filaments are placed on Unterkettfäden and mechanically connected by means of binding warp threads with the Unterkettfäden.
  • the surface heating element can be deformed. It can form a coating for an interior fitting of a motor vehicle, for example a steering wheel, an armrest or a trim part. In addition, it can be integrated into a vehicle seat.
  • the heating filaments are contacted directly by the electrically conductive connecting filaments.
  • at least some lower warp threads are electrically conductive and form spaced apart first and second lead regions which are each contacted by at least one connecting thread and which are electrically connected to one another via the heating filaments.
  • Two supply areas extending in the warp direction can thus be arranged at a distance from each other. Between the supply line areas extending electrically non-conductive fabric threads may be arranged in the warp direction, and by means of the filaments running in the weft direction, the lead areas may be electrically connected to each other.
  • the protruding from the fabric connecting threads can be connected, via which the supply areas with Power can be applied from a power source.
  • the filaments are arranged in circuit parallel to each other and are contacted by electrically conductive Unterkettfäden that distribute the electric current to the heating filaments, which is supplied to the Unterkettfäden on the connecting threads.
  • the electrically conductive textile explained above is suitable in particular for use in an interior fitting of a motor vehicle, the interior fitting having an electrically heatable surface heating element of the type described above.
  • the use of an electrically heatableêtnwarides in the form of an electrically conductive textile, as explained above, allows a structurally very simple and aesthetically pleasing design of the interior fitting. It may be provided, for example, that the heating filaments are arranged on the upper side of the surface heating element and thereby the heat radiation generated can be perceived directly by the vehicle user. This is particularly advantageous if the interior fitting is designed in the form of a vehicle seat, a steering wheel, an armrest or another surface element which forms an inner surface of a vehicle.
  • the interior fitting preferably has a base body which is at least partially covered by an electrically conductive textile, which, as explained above, comprises electrical connection threads which are web technically integrated into the tissue over a portion of their length and contact electrically conductive tissue threads. It can then be provided that the region of the base body coated by the electrically conductive textile has at least one passage through which at least one connecting thread is passed. The passage is thus of the electric covered conductive textile and is therefore not visible to the vehicle user. Through the passage, however, the at least one connection thread is passed, which is led out of the tissue, so that the electrically conductive tissue, invisible to the user, can be connected to a power source. Therefore, the edge area of the fabric need not be accessible for the connection of a connection cable, it can be guided around the edge of the base body to cover the visible side of the base body without having to ensure a free space for supplying a connection cable.
  • an electrically conductive textile which, as explained above, comprises electrical connection threads which are web technically integrated into the tissue over a portion of their length and

  • tie warp threads 20 which are also referred to as upper warp threads or leno warp threads.
  • the binding warp threads 20 give the fabric 12 a high sliding resistance.
  • the weft threads 18 are clamped between the lower warp threads 16 and the binding warp threads 20 and thus mechanically stably connected to the lower warp threads 16 and the binding warp threads 20.
  • the lower warp threads 16 are first electrically non-conductive fabric threads 22 and first electrically conductive fabric threads 24 are used. In each case a plurality of first electrically conductive fabric threads 24 are arranged directly next to one another and form a first electrical supply region 26 and at a distance to this a second electrical supply region 28, between which a plurality of first electrically non-conductive fabric yarns 22 are arranged.
  • the weft threads 18 are formed by spaced apart second electrically conductive fabric threads 30, between each of which a plurality of second electrically non-conductive fabric threads 32 are arranged.

  • the first electrically conductive fabric threads 24 have a relatively small length-specific electrical resistance.
  • the second electrically conductive fabric threads 30 have a relatively large length-specific electrical resistance.
  • the second electrically conductive fabric threads 30 form heating filaments 34 which, via the first electrically conductive fabric threads 24, are connected to a current source 46 (FIG. FIG. 4 ) can be connected.
  • the connecting threads 14, 15 are used, which are likewise electrically conductive.
  • the connecting threads 14, 15 are weaving-technically integrated into the fabric 12 only over a portion of their length, otherwise they stand out from the surface defined by the fabric 12.
  • the connecting threads 14 and 15 are placed in the supply line 26 and 28 on the first electrically conductive fabric threads 24 and just like a second electrically conductive fabric thread 30 of binding warp threads 20 overlapped.
  • the connecting threads 14 and 15 extend directly adjacent to a second electrically conductive fabric thread 30.
  • the connecting threads 14 and 15 run directly next to a second electrically non-conductive fabric thread 32, because even in this Case they are directly in contact with first electrically conductive fabric threads 24th
  • the free end regions 40 of the connecting thread 14 can be combined and connected to a first electrical connecting cable 44, such as it in FIG. 4 is shown.
  • the free end regions 42 of the connecting thread 15 can be combined and connected to a second connecting cable 45.
  • the electrically conductive textile 10 can be connected to the power source 46.
  • the electrically conductive textile 10 forms in the illustrated embodiment, an electrically heatable surface heating element, which can be connected via the connecting threads 14 and 15 to the power source 46.
