Definitions

  • the invention relates to an electrically heatable surface element for a vehicle seat according to the preamble of claim 1.
  • the WO 2007/031324 Discloses a heating element, comprising at least one layer of a matrix of functional fibers, wherein the matrix is electrically conductive and / or heated, via contact lines with a current or voltage source is connectable against each other electrically insulated conductive sections and at least partially exclusively non-metallic fibers as functional Fibers includes, for. B. carbon fibers. The production is not easy and the resistance is limited by the components used.
  • a fabric is used as a heating mat, which consists of carbon fibers, which have a relatively high electrical resistance.
  • each Zuhausens- or contact wires are provided at the ends.
  • One of the contact wires is grounded, while another is energized. Due to the potential difference, a current flows through the carbon fibers of the fabric to the grounded contact wire and thereby generates heat.
  • Such a heating mat theoretically allows a uniformly constant heat dissipation over the entire surface, but a concentration of heat development at certain locations with this heating mat is not possible.
  • the requirement for the carbon fiber fabric in terms of uniformity is very high in order to achieve a truly uniform heat distribution. This in turn complicates the manufacture, as noted above.
  • Another surface heating element is in DE 41 10 36 425 A1 disclosed.
  • sinusoidal weft threads are provided in a knitted textile base material, which act as a heat conductor.
  • power supply conductors are provided, to which the heating conductors are each performed.
  • special attention must be paid to the contacting of the heating conductors with the power supply conductors. This is achieved by a long contact distance, which is somewhat unfavorable.
  • the DE 10 2012 000 445 A1 discloses seat heating for a pad of a vehicle seat with at least one controllable by a control device and can be acted upon by electric current heating element, wherein the heating element has a heating layer, which is formed by a Schulack.
  • individual and demand-based heating elements should be produced in shape and size. Although this allows the geometry of the heating elements, but not set their electrical resistance.
  • the DE 102005050459 B3 discloses a flexible surface heating element for seat heaters, with a heating field of conductive fibers, which are electrically connected to a contact strip.
  • At least one contact strip contains a proportion of conductors in the form of steel filaments and a proportion of conductors in the form of filaments of a higher conductivity than the steel filaments, wherein the two types of conductors are electrically interconnected and held on a textile belt by means of textile and / or metallic threads become.
  • the higher conductivity conductors are wavy or meandering, crossing the respective steel conductors and being in contact with the former.
  • the higher conductivity conductors are above or below the steel filaments.
  • the surface heating element is to be able to continue to operate in the event of breakage of single thin filaments without overheating. Of course, the production is very expensive.
  • DE 41 24 684 A1 discloses a surface heating element integrated in an elastic carrier material, consisting of heating wires arranged substantially parallel, which are electrically connected at their ends and / or deflection points to current supply conductors are.
  • Each power supply conductor is designed as a flexible contacting strip with a plurality of individual conductors, which are electrically connected in parallel with the heating wires. This is an attempt to achieve greater flexibility for the electrodes / contact elements. Again, the production is quite complicated and the risk of overheating in fractures is not eliminated.
  • the WO 2005/020246 A1 discloses a process for making electrically conductive flexible sheets comprising applying an aqueous film-forming polymer composition comprising a binder B with a non-film-forming powder having core-shell morphology.
  • the shell-forming material consists of at least one noble metal or an alloy consisting predominantly of at least one noble metal.
  • the polymer composition is applied in the form of a reticulated pattern to the surface of a flexible, flat support which does not conduct electrical current.
  • EP 2457 944 A1 discloses an electrically heatable surface element for a vehicle seat according to the preamble of claim 1.

  • heating mats which, for a given geometry, have an electrical resistance and thus their specific heat output, i. are adjustable in the achievable temperature and can be used for accurate temperature control with a standard commercial seat heating control, where usually the electrical resistance of the heating surfaces must be known and specified in close tolerances.
  • a typical task in this regard is e.g. the heating of an automobile seat with heating elements in the seat, in two seat side panels, in the backrest surface and in the two backrest side panels by means of a commercially available seat heating control.
  • the heating surfaces are usually predominantly rectangular.
  • the surface elements according to the invention can also be combined with any alternative heating mats, with the same commercial controls can be used for temperature control.

  • the control technology of such seat heating control units allows error-free operation only within certain current limits.
  • the minimum current is greater than or equal to 2.1A and the maximum current is less than 12.8A.

For error-free operation, therefore, both heating circuits must have an electrical resistance between 0.94 and 11.4 ⁇ .
  • the surface heating elements according to the invention can now be adjusted in their resistance simply by the formation of the shape of the network or grid and by the coating thickness of the coating adapted to the grid shape so that they can be operated without problems with such a standard seat heating control.
  • An advantageous development in this sense also consists in that, in addition, the width-height ratio and the electrode spacing of the surface element can be adjusted after its application as a parameter for determining the total electrical resistance.
