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 electrically conductive threads can be arranged in different ways. For example, it is known to guide at least one electrically conductive thread meandering along the Schugewebes. However, there is the problem here that at a transection of the filament, the entire heating effect fails.
  • a surface heating element with a plurality of each consisting of a group of electrically conductive filaments heating bands, which are interconnected via plate-shaped connecting means is in the EP 1 835 786 A1 described.
  • the interconnection of the individual heating strips also results in a substantially meander-shaped course, whereby targeted areas with heating power and without heating power can be created.
  • the invention has for its object to provide a heating fabric, which provides a reliable heating effect and is flexibly dimensioned.
  • a first basic idea of the invention can be seen in the fact that a pigtail, which serves to connect the electrically conductive threads to a voltage source, is introduced into the heating fabric.
  • the pigtail extends along a surface formed by the heating fabric, that is to say in the plane formed by the heating fabric.
  • the pigtail may be incorporated into the tissue or applied to a tissue surface.
  • 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.
  • a preferred embodiment of the invention is to form the heating fabric in the pigtail as a hollow fabric.
  • the hollow tissue section comprises at least two separate layers of fabric and a channel-shaped cavity extending between the layers of fabric in a longitudinal direction along the fabric.
  • the pigtail extends along the longitudinal direction of the hollow tissue section or the cavity.
  • 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.
  • the fabric is preferably designed as a single layer.
  • the heating fabric is preferably designed as a single layer on both sides of the longitudinally extending hollow fabric section.
  • threads are understood as meaning all linear, textile structures which can be processed into fabrics, in particular yarns, wires and mono- and multifilaments
  • a preferred embodiment of the invention consists in that at least one first pigtail and at least one second Pigtail are provided and that in the region of the first pigtail a first hollow tissue section and in the region of the second pigtail a second hollow tissue section is formed.
  • one of the connecting leads forms a positive pole and the other pigtail forms a negative pole.
  • electrically conductive threads can pass electrically without contact or at least with reduced contact on both connecting leads. Further, it is possible to make the electrical connections on one side close to each other.
  • the connecting leads can also be provided on a common hollow fabric section. Due to the hollow space between the fabric layers, the connecting wires can be spatially separated from one another and thus insulated from one another.
  • two oppositely polarized connecting strands can be arranged on one and the same edge region of the region of the fabric to be heated. The heat is then generated not so between the two leads, but beyond both leads. The electrical connection is made only from one side of the heating area. In this way, it is ensured that the surface of the heating fabric to be heated largely can be cut free.
  • the heating fabric can thus be dimensioned particularly flexible.
  • the connecting leads can in principle be arranged at any point of the fabric.
  • the connecting strands preferably extend along an edge region of the fabric, in particular at a small distance from a side edge of the fabric. They preferably run along an edge of the heating fabric, at the edge of a region to be heated.
  • the at least two pigtails of different polarity are arranged parallel and / or at a small distance from one another, wherein the region between the pigtails is preferably unheated.
  • An improved conductivity along the pigtail can be generated by providing at least one pigtail strand comprising a plurality of pigtails.
  • a plurality of connecting leads are combined to form a stranded strand strand, which serves as an electrode for the electrically conductive threads.
  • An improved conductivity can also be achieved by using one or more films as pigtails in addition to or instead of wires or filaments. The film may in particular be drawn into the hollow fabric.
  • 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.
  • a further preferred embodiment of the invention consists in that the insulating separating layer is conductively coated on at least one side.
  • the separating layer is preferably conductively coated on a side facing the connecting strands.
  • the conductive coating may for example be formed by a flexible printed circuit board. If both connecting leads (plus and minus) are arranged on the same hollow tissue section, the insulating separating layer can also be conductively coated on both sides. Incidentally, a one-sided conductive coating is preferred.
  • the connecting wires run in the warp direction.
  • the electrically conductive threads preferably run transversely to the connecting strands, ie in the weft direction.
  • the invention provides that a first pigtail is connected to a plurality of first, electrically conductive threads and a second pigtail to a plurality of second, electrically conductive threads.

  • a first part of these supply lines, the positive pole and another part of the negative terminal of a circuit is closed.
  • the heat generation thus takes place significantly between the electrically conductive threads in the high-impedance resistance medium. Due to the preferably uniformly distributed in the surface to be heated supply lines and the high compared to the resistance medium conductivity of the supply leads, a uniform heat effect can be generated in the heating fabric.
  • Another aspect is to connect all electrically conductive threads of the same polarity (plus or minus) each to a common pigtail or stranded wire unit.
  • a first group of electrically conductive threads is thus connected to a first pigtail, which for example forms a positive pole, and a second group is connected to a second pigtail, which then forms the negative pole.
  • the threads do not contact the respective other pigtail, so that there is an electrical separation between the plus threads and the minus threads.
  • the electrically conductive threads are therefore each connected to only one of the connecting leads (plus or minus).
  • 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.
  • a high-impedance conductor medium is understood in particular to mean a conductor medium in which heat can be generated by applying a voltage and which has a higher electrical resistance than the electrically conductive supply line threads.
  • the electrically conductive threads of the first pigtail and those of the second pigtail are evenly distributed over the tissue, which is to be understood as meaning that the return lines are distributed either alternately or in another predetermined, regular sequence over the surface of the fabric.
  • a multiplicity of circuits is formed along the surface of the tissue, wherein a uniform heating effect is produced by the uniform arrangement of the electrically conductive threads.
  • a high-impedance conductor medium can be provided according to a preferred embodiment of the invention, at least one high-impedance thread.
  • a multiplicity of high-impedance filaments are arranged transversely to the electrically conductive filaments. The high-resistance filaments thus each contact a multiplicity of electrically conductive filaments, which are alternately connected to the two connecting strands or stranded strands.
  • 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.
