Definitions
- the invention relates to a heating fabric according to the preamble of claim 1.
- a heating fabric comprises threads running in the warp direction and in the weft direction, at least part of the threads being designed as electrically conductive threads.
- Heating fabric of this type are used for example for seat heaters in vehicles.
- a voltage is applied to the electrically conductive threads.
- the electrical resistance of the filaments generates heat that is used to heat the seat.
- the pigtail is conductively connected to at least a portion of the electrically conductive strands to connect the electrically conductive strands to the voltage source.
- the connecting leads which can also be referred to as connection electrodes, serve for the common connection of the electrically conductive threads to the voltage source.
- two mutually insulated or isolatable tissue areas are provided.
- electrically conductive threads Crossing the pigtail without contacting by the pigtail is disposed on one of the fabric layers and extend the electrically conductive threads on the respective other fabric layer.
- a portion of the electrically conductive threads or one of the pigtail opposite end of an electrically conductive thread can be performed on the pigtail over to a mutual-pole voltage connection.
- electrically conductive material for the at least one pigtail is, for example, copper or silver into consideration.
- electrically conductive material for the at least one pigtail is, for example, copper or silver into consideration.
- a pure copper or silver strand can be provided.
- a conductive coated thread for example a silver-plated, tinned or nickel-plated copper strand.
- an insulating separating layer can be introduced into the cavity.
- the insulating separating layer for example an insulating film, ensures that even with a spatial approximation of the two layers of the hollow tissue section, For example, by a tensile load of the fabric, a reliable insulation is maintained.
- the selective connection of the electrically conductive threads with the first or the second pigtail can be realized reliably by passing the threads on the non-contact pigtail on the respective other fabric layer of the hollow fabric section.
- the electrically conductive threads preferably run parallel to one another and do not contact each other in this way.
- the electrically conductive threads can extend along the entire longitudinal or weft direction of the fabric, without contacting the transverse thereto, each opposite polarity pigtail.
- the electrically conductive threads which extend as supply lines into the region to be heated, are preferably aligned transversely to the connecting leads. In the area of the surface to be heated, the electrically conductive threads are electrically connected to one another via the high-resistance conductor medium.
- the high-resistance thread is looped around by at least one pair of threads of the electrically conductive threads, wherein a first thread of the pair of yarns the high-resistance thread on a first fabric side and a second thread of the pair of yarns contacted the high-impedance thread on a second fabric side.
- the feeder threads in the weft direction are therefore each carried out twice, so that the high-resistance thread is better wrapped or contacted.
- the first connecting strands 32 are web-technically connected to the first electrically conductive threads 62.
- the second connecting strands 52 are web-technically connected to the second electrically conductive threads 64. In terms of binding, no second electrically conductive threads 64 make contact with the first connecting leads 32 and vice versa.
- Fig. 2 shows a cross-sectional view of the terminal portion 16 of the heating fabric 10 with its two hollow fabric sections 20, 40.
- the first hollow fabric section 20 has an upper fabric layer 22 and a lower fabric layer 24.
- the second hollow fabric section 40 has an upper fabric layer 42 and a lower fabric layer 44.
- the first connecting strands 32 are arranged on the upper fabric layer 22 of the first hollow fabric section 20.
- the second connection strands 52 are arranged on the lower fabric layer 44 of the second hollow fabric section 40.
- the threads 62 electrically connected to the first connecting strands 32 extend along the upper fabric layer 42 of the second hollow fabric section 40 and the threads 64 connected to the second connecting strands 52 extend along the lower fabric layer 24 of the first hollow fabric section 20. In this way, the threads are 62 of the connecting leads 52 and the threads 64 of the connecting leads 32 are electrically isolated.
- the first connecting leads 32 and the second connecting leads 52 can also be referred to as positive poles or negative poles, which are to be connected to a voltage source.
- the electrically conductive threads 62, 64 are electrically connected to one another along a heating region 60 or a surface of the heating fabric 10 to be heated by means of a high-resistance conductor medium.
- the high-resistance conductor medium which is formed in the first embodiment of the heating fabric 10 by a plurality of high-resistance filaments 66 running transversely to the supply fibers 62, 64, generates a uniform heating over the entire heating region 60.
- the high-resistance filaments 66 running in the warp direction intersect the electrically conductive filaments 62, 64 and in this way produce a multiplicity of electrical circuits over the heating surface of the fabric.
- Fig. 3 shows a preferred thread guide in the heating surface of the fabric.
- the electrically conductive threads 62, 64 are each executed in duplicate, that is, between non-conductive weft threads 12 are at least two electrically conductive threads 62 or 64, which loop around the high-resistance thread 66 on opposite sides, so that the thread 66 is looped around on both sides , Due to the paired arrangement of electrically conductive threads 62, 64 between the non-conductive threads 12, a particularly good contacting of the high-resistance threads 66 is achieved.
- one hollow space can be inserted into the hollow tissue sections 20, 40 Separator or separating layer 34, 54 introduced.
- the separating device 34, 54 may in particular comprise a release film, which is drawn into the heating fabric 10 along the respective hollow fabric section 20, 40.
- the separating foil may be electrically coated on its side facing the pigtail.
- FIG Fig. 4 A second embodiment of a heating fabric 10 according to the invention is shown in FIG Fig. 4 shown.
- the heating fabric 10 is provided in the area to be heated with a high-resistance coating 68.
- the heating fabric 10 may be coated with a resistance paste.
- the connection region 16, in which the connecting leads 32, 52 are arranged, is preferably not coated.
- the already finished woven fabric is coated.
- the power supply is distributed over the threads 62, 64 on the surface and passed into the resistive coating. In the resistance coating, the heat is generated.
- the distance between the threads 62, 64 is determined by the operating voltage, the resistance paste or the paste thickness and the desired heating power.
- Fig. 5 shows a possibility of realization of a cable connection for the electrode wires 32, 52.
- a plate angle 70 is clamped on the electrodes.
- the sheet metal bracket 70 connects all the connecting leads 32, 52 of a stranded strand 30, 50 and forms a connection device for a voltage source, not shown in the figures.
- a conductive foil for example a copper foil
- Fig. 6 shows a way to heat a fabric with a hole 18 over its entire surface.
- two Gleichpolige connecting strands 32, 52 are provided on opposite tissue areas or fabric edges in each case.
- individual electrically conductive threads 62, 64 are cut through the hole 18, the heating fabric 10 is heated along the entire heating region 60.
- the electrically conductive threads 62 are electrically conductively connected to first connecting leads 32 arranged on opposite sides of the hole 18.
- the second electrically conductive threads 64 are connected to two corresponding connection strands 52 on opposite sides of the hole 18.
- the pigtails 32, 52 may be embodied as pigtails strands 30, 50. If there are several holes in the same line, there should be more intermediate pigtails to ensure power between adjacent holes.
