Definitions

  • the invention relates to a cover material comprising a textile carrier material made of threads and a coating applied on the visible side of the textile carrier material based on thermoplastic and / or thermosetting plastics, the textile carrier material containing threads of low tear resistance to form predetermined breaking points for the cover material.
  • cover materials are used, for example, to cover safety-relevant systems, such as an airbag unit in motor vehicle interiors as a cover material or surface material for instrument panels, door panels, seat constructions and the like, in order to hide the airbag unit under a visually appealing surface.
  • Covering materials known to date from the prior art are based, for example, on artificial leather and leather, whereby it is necessary to pay particular attention to the positioning of the covering materials, since the predetermined breaking points worked into the covering material are exactly over by so-called tear threads or on the back, for example by means of laser processing the airbag unit must be positioned in order to ensure the correct function of the airbag unit.

  • a cover material designed in this way can be positioned at will, because regardless of its positioning, it always allows access to the security system or its deployment due to the low maximum tensile force inherent in the cover material, regardless of the orientation of the cover material.
  • the cover material according to the invention is a planar sheet-like structure which extends in every direction, i. H. has comparable strength values longitudinally and transversely as well as at any angle.
  • the safety function of the cover material due to its tear-open capability is guaranteed at any point and orientation so that it can be positioned anywhere.
  • the effort for positioning and the previously unavoidable waste can therefore be reduced to a minimum.
  • the cover material according to the invention can be used in particular to cover safety-relevant devices, such as airbags in a motor vehicle, underframe sprinklers in the interiors of buildings, and to encase expandable life rafts, life jackets and the like.
  • the maximum tensile force of the cover material according to the invention is selected so that, for example, when a covered airbag unit is triggered, the cover material reliably tears open regardless of its position and ensures the function of the airbag unit.
  • the separation force within the temperature range between ⁇ 45 ° C. and 130 ° C. that is to be expected for the operation of a motor vehicle is selected to be so high that separation or separation of the carrier material from the coating is reliably excluded.
  • the cover material according to the invention allows extraordinary freedom and variety of design due to its almost arbitrary positionability, since possible cuts from the cover material according to the invention, which is usually manufactured as a web material, can have very narrow radii.

  • a single layer can be formed from a layer thickness of about 1 ⁇ m.
  • At least one layer of the coating can comprise a lacquer layer applied on the visible side, whereby several, for example up to 4 lacquer layers can also be combined with one another in order to achieve desired functional layers, for example to achieve abrasion resistance or water-repellent properties, as well as printed layers for a desired color.
  • the degree of gloss and the feel can also be adjusted accordingly.
  • the visible surface of the cover material according to the invention can also be provided with a profile, for example an embossing / structuring, e.g. in the manner of a textile structure or a technical grain or leather grain, in order to form an artificial leather. Fantasy structures can also be introduced as required.
  • a profile for example an embossing / structuring, e.g. in the manner of a textile structure or a technical grain or leather grain, in order to form an artificial leather. Fantasy structures can also be introduced as required.
  • Such an embossing can be formed, for example, by vacuum embossing, embossing between steel or silicone roller pairs and by building up the coating on a removable profiled base, for example a release paper, grain tape or a steel carrier tape in the so-called reverse process.
  • Multilayer composite systems based on calendered films and their combinations can also be created, which can also be manufactured without removable auxiliary carriers such as release paper or grain tape.
  • the textile carrier material and / or the coating can be equipped with flame retardant properties according to the requirements.
