Abstract
Description
Die Erfindung betrifft einen Heizleiter, insbesondere für Heizelemente eines Kfz-Sitzes.The invention relates to a heating conductor, in particular for heating elements of a motor vehicle seat.
Zum Beheizen von Sitzen insbesondere in Personenkraftwagen werden hauptsächlich verzinnte oder versilberte Kupferleiter eingesetzt. Diese Heizleiter zeigen trotz dieser Beschichtung in Abhängigkeit von den Umgebungsbedingungen Korrosionserscheinungen, die durch Feuchtigkeit und Salzeinfluß induziert werden. Aufgrund dieser Korrosionserscheinungen kommt es zu die Heizleiter schädigenden Querschnittsreduzierungen, folglich zu lokalen Überhitzungen und schließlich zu einem Bruch des Heizleiters, was in einer verkürzten Lebensdauer des Heizleiters resultiert. Desweiteren kann die Beschichtung mit Silber oder Zinn oder auch anderen Metallen die Reibung der Einzelfilamente des Heizleiters untereinander so weit erhöhen, daß der Heizleiter aufgrund seiner erhöhten Steifigkeit abknicken und somit stark beschädigt werden kann. Ein weiterer Nachteil einer metallischen Beschichtung der einzelnen Heizleiterfilamente liegt in dem stark unterschiedlichen Redoxpotential der Beschichtungsmetalle gegenüber dem eigentlichen Drahtmaterial. Für den Fall, daß die Beschichtung nicht porenfrei ist und Fehlstellen vorhanden sind, setzt unter Einfluß eines aus Wasser und Salz gebildeten Elektrolyten Korrosion und damit die Auflösung des unedleren Metalls ein, was wiederum eine Beschädigung des Heizleiters darstellt.Mainly used to heat seats, especially in passenger cars tinned or silver-plated copper conductors are used. Despite this, these heating conductors show Coating depending on the environmental conditions which are induced by moisture and salt influence. Based on these Signs of corrosion will damage the heating conductor Cross-sectional reductions, consequently to local overheating and eventually to one Breakage of the heating conductor, which results in a shortened service life of the heating conductor. Furthermore, the coating with silver or tin or other metals Increase the friction between the individual filaments of the heat conductor so far that the heat conductor kink due to its increased rigidity and can therefore be severely damaged. Another disadvantage of a metallic coating on the individual filaments of the heating conductor lies in the very different redox potential of the coating metals compared to the actual wire material. In the event that the coating is not pore-free and Flaws are present, is influenced by one formed from water and salt Electrolyte corrosion and thus the dissolution of the less noble metal, which in turn represents damage to the heating conductor.
Aus dem vorgenannten ergibt sich das Problem, mit Hilfe eines neuartigen Heizleiters die obengenannten Nachteile zumindest teilweise zu beseitigen. Das sich ergebende Problem besteht insbesondere darin, einen Heizleiter bereitzustellen, der gegenüber in Sitzen auftretenden Korrosionserscheinungen resistent ist und eine hohe mechanische Flexibilität aufweist.The problem arises from the above, with the help of a novel heating conductor to at least partially eliminate the above-mentioned disadvantages. The problem that arises consists in particular in providing a heating conductor, which is located opposite in seats occurring corrosion is resistant and high mechanical flexibility having.
Dieses Problem wird erfindungsgemäß durch einen Heizleiter nach Anspruch 1, ein Gewirke nach Anspruch 11, ein Heizelement nach Anspruch 13, eine Sitzheizung nach Anspruch 14, einen Sitz nach Anspruch 15 und eine Verwendung nach Anspruch 16 gelöst.This problem is solved according to the invention by a heat conductor according to claim 1, a knitted fabric according to claim 11, a heating element according to claim 13, a seat heater according to claim 14, solved a seat according to claim 15 and a use according to claim 16.
Der erfindungsgemäße Heizleiter besteht im wesentlichen aus nahezu in einem Strang zueinander verlaufenden (entweder im wesentlichen zueinander parallel oder miteinander verdrillt), sich berührenden Einzelleitern aus leitfähigem Material, wobei mindestens ein Einzelleiter durch eine Isolation von allen anderen Einzelleitern elektrisch getrennt ist.The heating conductor according to the invention essentially consists of almost one strand to each other (either essentially parallel to each other or to each other twisted), touching individual conductors made of conductive material, at least one Individual conductors are electrically isolated from all other individual conductors by insulation.
Es ist vorteilhaft, wenn die Einzelleiter monofil sind, da durch diese Art der Ausgestaltung eine besonders hohe Flexibilität erreicht wird.It is advantageous if the individual conductors are monofilament, because of this type of design a particularly high degree of flexibility is achieved.
Weiterhin ist es von Vorteil, daß jeder Einzelleiter durch eine Isolation von allen anderen Einzelleitern elektrisch getrennt ist, um auf diese Art und Weise eine maximale Korrosionsresistenz bereitzustellen und bei lokaler Zerstörung der Einzelleiter eine unerwünschte Temperaturerhöhung an der jeweiligen Bruchstelle zu vermeiden.Furthermore, it is advantageous that each individual conductor is isolated from all others by isolation Individual conductors are electrically isolated in order to achieve maximum Provide corrosion resistance and a in the event of local destruction of the individual conductors to avoid undesirable temperature increases at the respective break point.
Darüberhinaus ist es vorteilhaft, daß die Einzelleiter an ihren längsachsialen Enden elektrisch leitend verbindbar sind, beispielsweise mit einer Spannungsquelle bzw. den eigentlichen Heizelementen einer Sitzheizung verbunden werden zu können, um eine gut zugängliche Kontaktierungsmöglichkeit zu haben. Dieses wird dadurch erreicht, daß der thermische Zersetzungspunkt der Isolierung so gewählt ist, daß die Einzelleiter an ihren Enden in einem Bad aus flüssigem Zinn von der Isolierung befreit und durch das Zinn miteinander verbunden werden.In addition, it is advantageous that the individual conductors are electrical at their longitudinal axial ends are conductively connectable, for example with a voltage source or the actual one Heating elements of a seat heater can be connected to an easily accessible To have contact possibility. This is achieved in that the thermal Decomposition point of the insulation is chosen so that the individual conductors at their ends in one Bath made of liquid tin freed from the insulation and connected by the tin become.
Es ist auch von Vorteil, daß die Isolation aus mehreren Schichten besteht, da damit eine dichte und dennoch flexible Isolation erzeugt werden kann.It is also advantageous that the insulation consists of several layers, since it is one tight, yet flexible insulation can be created.
Die Isolation besteht vorteilhafterweise aus Polyurethan, weil auf diese Weise eine flexible, hochisolierende und mechanisch hoch beanspruchbare Schicht erzeugt wird.The insulation is advantageously made of polyurethane, because in this way a flexible, highly insulating and mechanically highly stressable layer is produced.
Die Isolation besteht vorteilhafterweise aus mindestens einer inneren Schicht aus Polyurethan und mindestens einer äußeren Schicht aus Polyester oder Polyacrylat, da Polyurethan selbst Wasser und Feuchtigkeit aufnehmen kann und die äußere Schicht aus Polyester oder Polyacrylat den direkten Kontakt der Einzelleiter mit Wasser unterbindet. Auf diese Weise besteht ein sehr wirksamer Schutz vor Wasser.The insulation advantageously consists of at least one inner layer made of polyurethane and at least one outer layer made of polyester or polyacrylate, since polyurethane itself Can absorb water and moisture and the outer layer of polyester or Polyacrylate prevents direct contact of the individual conductors with water. In this way there is a very effective protection against water.
Weiterhin ist es von Vorteil, wenn die Einzelleiter aus Kupfer oder leitfähigem Kunststoff bestehen, da sich diese Materialien in der Praxis bewährt haben. Als leitfähige Kunststoffe haben sich insbesondere stark mit Carbon (Ruß, Kohlenstoff) versetzte Kunststoffe bewährt, da bei kleinen Netzspannungen eine hohe Leitfähigkeit gewährleistet sein muß.Furthermore, it is advantageous if the individual conductors are made of copper or conductive plastic exist because these materials have proven themselves in practice. As conductive plastics have proven themselves especially with carbon (soot, carbon) mixed plastics, since high conductivity must be guaranteed at low mains voltages.
Darüberhinaus ist es vorteilhaft, daß mindestens ein Einzelleiter aus einem Material besteht, welches seinen elektrischen Widerstand in Abhängigkeit der Eigentemperatur ändert, da ein solcher Einzelleiter als Temperatursensor fungieren kann. Als Material haben sich Nickel, Eisen oder Legierungen bewährt, die einen hohen Temperaturkoeffizienten aufweisen und so ein großes Ausgangssignal in Form einer Widerstandsveränderung erzeugen.In addition, it is advantageous that at least one individual conductor consists of a material which changes its electrical resistance depending on the intrinsic temperature, since a such a single conductor can act as a temperature sensor. Nickel has become the material Iron or alloys have proven that have a high temperature coefficient and so generate a large output signal in the form of a change in resistance.
Schließlich ist es vorteilhaft, wenn sämtliche Einzelleiter von einer äußeren Isolationshülle aus FEP (Tetrafluorethylen-Hexafluorpropylen), Silikon (gemeint sind hier die üblicherweise eingesetzten Silikonharze) oder PTFE (Polytetrafluorethylen) ummantelt sind, um einen weiteren mechanischen wie elektrischen Schutz des Heizleiters zu gewährleisten.Finally, it is advantageous if all of the individual conductors are covered by an outer insulation sheath made of FEP (tetrafluoroethylene-hexafluoropropylene), silicone (what is usually meant here used silicone resins) or PTFE (polytetrafluoroethylene) to be covered to ensure further mechanical and electrical protection of the heating conductor.
Ein einen erfindungsgemäßen Heizleiter enthaltendes Gewirke weist die oben genannten vorteilhaften Eigenschaften auf, wobei es als besonders positiv anzusehen ist, wenn der Heizleiter im Teil- oder Kurzschuß (unter diesen Bezeichnungen sind die auf dem Gebiet der Wirktechnik üblichen Begriffe mit ihren entsprechend semantischen Inhalten gemeint) in das Gewirke eingebunden ist, da auf diese Art und Weise der Heizleiter in eine textile Umgebung eingebunden ist, die äußere Kräfte aufnimmt und den Heizleiter so vor hohen Zugkräften schützt. Durch die textile Einbindung im Teil- oder Kurzschuß ist ein wellenförmiger Verlauf des Heizleiters im Textil gegeben, ohne daß es zu scharfen Knicken oder hohen Zugbeanspruchungen kommen kann. Das Gewirke-Material besteht insbesondere aus einem Polyester, Polyethylen oder Baumwolle.A knitted fabric containing a heating conductor according to the invention has the above-mentioned advantageous properties, it being particularly positive if the Heating conductor in partial or short shot (under these names are those in the field of Terms of knitting technology with their corresponding semantic content) in the Knitted fabric is involved, because in this way the heating conductor is in a textile environment is integrated, absorbs the external forces and the heating conductor against high tensile forces protects. Due to the textile integration in the partial or short weft there is a wavy course of the heat conductor in the textile, without sharp kinks or high Tensile stresses can come. The knitted material consists in particular of a Polyester, polyethylene or cotton.
Ein mindestens einen erfindungsgemäßen Heizleiter enthaltendes Heizelement und eine diesbezügliche Sitzheizung weisen die oben genannten Eigenschaften auf. Es sei daher ausdrücklich darauf hingewiesen, daß einzelne Heizelemente einer elektrischen Sitzheizung erfindungsgemäß aus dem erfindungsgemäßen Heizleiter bestehen können. A heating element containing at least one heating conductor according to the invention and one relevant seat heating have the above-mentioned properties. It is therefore expressly pointed out that individual heating elements of an electric seat heater according to the invention can consist of the heating conductor according to the invention.
Ein erfindungsgemäßes Gewirke enthaltender Sitz, insbesondere ein Kfz-Sitz, weist die oben genannten Eigenschaften auf.A seat containing knitted fabrics according to the invention, in particular a motor vehicle seat, has the above properties.
In diesem Zusammenhang ist die Verwendung eines erfindungsgemäßen Heizleiters zur elektrischen Verbindung einer durch einen Abspanngraben eines Sitzes geteilten elektrischen Sitzheizung zu erwähnen, die sich in der Praxis als ausgesprochen wichtig herausgestellt hat. Unter dem Begriff "Abspanngraben" ist der Bereich eines gepolsterten Sitzes zu verstehen, an dem ein äußerer Sitzbezug "nach innen" gezogen und mit einem inneren Trägerrahmen befestigt wird. Es entsteht quasi ein "Graben", der wiederum von zwei benachbarten Polsterwulsten umgeben ist. Das Abspannen des Sitzbezuges dient in erster Linie dazu, bei nicht-profilierter Sitzoberfläche eventuelle auftretende Verwerfungen des Sitzbezuges zu vermeiden.In this context, the use of a heating conductor according to the invention for electrical connection of an electrical divided by a guy trench of a seat To mention seat heating, which has proven to be extremely important in practice. The term "guy trench" is to be understood as the area of an upholstered seat an outer seat cover "pulled in" and with an inner support frame is attached. A "ditch" is created, which in turn is created by two neighboring ones Upholstery beads is surrounded. Unclamping the seat cover primarily serves to to non-profiled seat surfaces to avoid any warping of the seat cover avoid.
(Unter der Bezeichnung "Abspanngraben" ist somit der auf dem Gebiet der Polsterung von Sitzen übliche Begriff mit seinem entsprechend semantischen Inhalt gemeint.)(Under the name "guy trench" is the one in the field of upholstery from Sitting usual term meant with its corresponding semantic content.)
Das nachfolgende Beispiel dient zur näheren Erläuterung der Erfindung.The following example serves to explain the invention in more detail.
Ein mehrere Abspanngräben aufweisender Kfz-Sitz enthält eine elektrische Sitzheizung aus mehreren Teilen, insbesondere einzelnen Heizelementen. Die einzelnen Heizelemente verlaufen in unmittelbarer Nähe entlang der Abspanngräben quasi "in den Polsterwulsten" des Sitzes. Die Heizflächen sind untereinander jeweils mit einem Heizleiter mit folgenden Merkmalen elektrisch verbunden, wobei der Heizleiter im Teilschuß in ein Gewirke aus Polyester eingebunden ist.A motor vehicle seat which has several guy trenches contains an electric seat heater several parts, especially individual heating elements. The individual heating elements run in the immediate vicinity along the guy trenches, so to speak "in the upholstery beads" of the Seat. The heating surfaces are each one with a heating conductor with the following Features electrically connected, the heat conductor in the partial shot in a knitted fabric Polyester is included.
Der Heizleiter selbst besteht im wesentlichen aus nahezu in einem Strang zueinander laufenden, sich berührenden Einzelleitern aus Kupfer, wobei jeder Einzelleiter monofil ist und durch eine aus einer inneren Schicht aus Polyurethan und einer äußeren Schicht aus Polyester bestehenden Isolation von allen anderen Einzelleitern elektrisch getrennt ist. Die Einzelleiter sind an ihren längsachsialen Enden über ein Lötzinn elektrisch leitend miteinander verbunden. Sämtliche Einzelleiter sind von einer äußeren Isolationshülle aus PTFE ummantelt.The heat conductor itself essentially consists of one another in almost one strand running, touching individual conductors made of copper, each individual conductor being monofilament and by an inner layer made of polyurethane and an outer layer made of polyester existing insulation is electrically isolated from all other individual conductors. The single ladder are electrically connected to each other at their longitudinal axial ends via a tin solder. All individual conductors are encased in an outer insulation jacket made of PTFE.
