Definitions

  • the invention relates to a cushion core according to the preamble of claim 1 and a method for its production.
  • the upholstery cores of previous aircraft seats generally consist of a suitable polyurethane foam.
  • all of the upholstery materials under consideration in the event of a fire neither develop toxic smoke gases nor contribute to the spread of fire.
  • these are covered with fire-proof covers. In this way, ignition is avoided and the release of poisonous gases from such upholstery in the event of a fire is substantially reduced.
  • the complete covering with refractory covers is technically difficult or impossible in many cases (e.g. in the case of penetrating parts such as support pipes, etc.), so that upholstered foam liquefied by the action of heat can drip off and burn out on the floor. Therefore, in many cases, such fabric coverings cannot offer adequate fire protection.
  • poisonous gases are created, which are also explosive.
  • Silicone foam is also known as the material for producing such upholstery. Although this has the values required for flammability and flue gas development, it is disadvantageous for reasons of weight. Parts consisting of this material can only be formed from one block.
  • the object of the invention is to design a cushion core of low weight using suitable materials in such a way that it has the properties required in terms of flammability and flue gas development, so that special envelopes are not required to achieve these properties and Upholstery core can be molded in one operation.
  • FIG. 2 shows a mold for producing an upholstery core.
  • FIG. 3 shows a section of an upholstery core with knot points and
  • Substitute H'-tt Fig. 4 shows a section of an upholstery core with welds.
  • FIG. 1 shows a head cushion 1 with a cushion core 2, a covering 3 and a fabric cover 4.
  • the cushion 1 is held by a U-shaped support 5 which penetrates the cushion core 2.
  • the core 2 consists of relatively temperature-resistant fibers 6, preferably of synthetic fibers. Such upholstery can be used in the automotive and furniture industries in addition to the aerospace industry.
  • the individual fibers 6 are arranged inside the cushion 2 in preferably irregularly running spatially curved lines, so that these are predominantly subjected to bending when the cushion is loaded. As a result of the elasticity of the fibers 6, the cushion 2 takes on its original shape again and again after relief.
  • plastics is between 1.1 and 1.5 g / cm. This makes it possible to manufacture upholstery cores that are used in one
  • the following materials can be used as basic materials for the production of the fibers 6.
  • PEEK Polyether ether ketone
  • PEI Polyetherimide
  • Figure 2 shows a mold 7 for the manufacture of cushion cores.
  • This shape 7 consists of an upper half 8 and a lower half 9, which touch in the parting plane 10.
  • the shape 7 is partially cut.
  • the cavity shown in dashed lines has the shape of the pad 11 to be produced.
  • the halves 8, 9 have cooling channels 12 for a cooling liquid.
  • Arranged within the mold 7 are two nozzles 13 and 14, each of which has a large number of small bores 17 and are designed to be displaceable in the direction of the arrows 15 and 16.
  • a suitable plastic is extruded through the holes 17 into the cavity of the mold 7.
  • FIG. 3 shows in a section of a cushion core with fibers 6 a further embodiment of the invention.
  • fertilizer This consists in that the fibers 6 are provided with a coating which surrounds them as thin skin and forms nodes 19 at the points of contact of the fibers 6.
  • the coating can be applied by dipping or spraying and generally consists of a suitable resin, for example based on polyimide. It is also conceivable that a silicone elastomer is used as the coating material. This further increases the heat resistance of the fibers 6. It is also conceivable that hollow microspheres containing fire-retardant active substances are mixed into the coating.
  • FIG. 4 shows a further embodiment of a cushion.
  • the fibers 6 are welded together at their contact points.
  • the welds 20 result automatically if the intrinsic temperature of the fibers is sufficient for this after extrusion.
  • One embodiment of the molding process is that the extrusion takes place from above into an open mold and the mold is only closed afterwards.
  • the nozzles perform controlled movements in order to distribute the fibers evenly.
  • a further embodiment of the invention consists in the fibers 6 of the cushion core being made of different materials.
  • the core 2 within the mold 7 is provided with a skin which preferably consists of a silicone material.
