Definitions

  • the invention is directed to a molded foam cushion, the surface of which has elevations in the form of cylinders, cones, truncated cones, pyramids, truncated pyramids, spherical caps, cuboids, prisms, ribs and the like.
  • Such upholstery cushions are used in the furniture sector and above all in the vehicle sector.
  • Another known possibility is the working out of separate recesses, whereby a reduction in the hardness in partial areas of cushion elements has been achieved by reducing the load-bearing foam volume.
  • the former manufacturing processes are cumbersome and labor intensive.
  • the latter method is much more efficient; there is no optimal adaptation to the human body.
  • the above-mentioned cushion cushions always show indentations under load, i.e. that is, in addition to the directly loaded areas - e.g. B. in automobile seats through the thighs of the passenger - the non-loaded neighboring areas are deformed by lateral tensile stresses. This means that the desired local differences in hardness cannot be set.
  • the object of the invention is that an upholstery cushion is found which has an indentation characteristic which is optimal for the body and for the stress.
  • the elevations can be foamed at the same time as the cushion cushion during the molded foaming process and that, for example, elevations of a different geometry can be provided in the area of the buttocks in the area of the buttocks than in the area of the less stressful thighs.
  • the elevations can have a wide variety of configurations. Size and height are also of particular influence.
  • a reaction system which, for example, forms polyurethane foam with high indentation hardness is used to produce the foam-molded cushion.
  • the areas of the cushion that can be adjusted to be softer are obtained by dimensioning the knobs accordingly. In this way, cushion cushions with increasingly different hardness can be produced, in which the transition from one degree of hardness to the other can be adjusted almost continuously.
  • the cushion cushion 1 has side reinforcements 2, between which the actual seat 3 extends.
  • This seat 3 is covered with three groups 4, 5, 6 of frustoconical elevations 7 of different sizes and heights.
