Definitions

  • the invention relates to a method for producing mattresses, chair seats or the like.
  • the invention is based on the object of developing this method for producing mattresses, chair seats and the like.
  • Upholstery elements in the sense of shortening the production time and improving the quality of the unit consisting of the two foam blocks and the spring elements.
  • this object is achieved in that a layer of a liquid, hardenable and self-extinguishing polyurethane is applied to the inner contact surface of the foam block provided for anchoring the ends of the spring elements, that the ends of the spring elements are inserted into the still liquid polyurethane layer and that the polyurethane layer is then cured while avoiding foaming.
  • the advantages achieved by the invention are essentially that the anchoring of the ends of the spring elements on at least one foam block is now independent of its actual manufacture, so that prefabricated foam blocks of any shape can be used, which are otherwise also provided for other purposes.
  • the application of the polyurethane layer on one surface of such a foam block is very easy to carry out, as is the insertion of the ends of the spring elements into the still liquid polyurethane layer, which hardens cold in just a few minutes, which then already firmly anchors the ends of the spring elements to the foam block is guaranteed.
  • the polyurethane layer also has an intimate connection with the foam block due to certain impregnation effects with regard to the pores of the foam, as a result of which the support surface receives a very effective abutment for the ends of the spring elements due to the polyurethane layer, which also penetrates the foam block and thus with a greater pressure load prevent its destruction.
  • the polyurethane layer is also flexible and can therefore follow any evasive movement of partial areas of the foam block under pressure, which means that the risk of premature spring breaks is correspondingly low.
  • the mattress consists of two foam blocks 1, which are cast from polyurethane.
  • the foam blocks 1 rest with outer contact surfaces on lying surfaces 3 and, with their inner contact surfaces, delimit an intermediate space 2 in which spring elements 4 are arranged.
  • the ends of these spring elements 4 are anchored to the two foam blocks 1 by means of a layer 5 made of a liquid, curable and self-extinguishing polyurethane.
