It will a basic element with cylindrical, transverse cavities, e.g. Elongated holes, manufactured or the elongated holes mechanically introduced after the production of a full basic element. Finally, the basic element is parallel to the lying or Separated seat level. Depending on the respective options the manufacturer can use the basic element as above or else as halves or as open, contiguous halves with semi-cylindrical recesses. The hollows can take up the mattress width in their length or shorter than the mattress width.
  • the elongated holes and thus the insert parts extend in the Interior of the mattress, the mattress core or basic element, so that there are no impairing depressions on the contact surface or ridges arise.
  • the basic element of two basic element parts lying one above the other parallel to the support plane.
  • the user only needs the upper basic part take off to the insert parts desired by him insert, exchange with each other or with new ones.
  • the basic element into more than two basic element parts.
  • the construction and Maintaining dimensional stability of the basic element is the basic element in two parts with a connection of the basic element parts a respective edge, preferably a longitudinal edge. Any wrappings are removed and the basic element is opened and the insert parts distributed in the elongated holes.
  • Suitable for the hollows, recesses or elongated holes Appropriate insert parts of different hardness manufactured. In this way, the user can insert parts accordingly Choose hardness for its needs and into the elongated holes deploy.
  • the insert parts can with each other or Part can be exchanged for new, different hardness if the chosen one Distribution of the degrees of hardness along the mattress not the corresponds to individual burdens.
  • cylindrical elongated holes and insert parts with square, cuboid, oval, poligonal cross to understand cut.
  • the simplest forms in terms of production technology are cylinders with a round cross-section.
  • the cross section of the elongated holes and that of the insert parts are usually have the same shape and dimension. It is but also possible to provide different shapes. At the combination of elongated holes with round and insert parts with poligonal cross sections, for example, can be the result Longitudinal gaps serve as ventilation holes. Ventilation holes are also achieved with the same cross-section in that the Insert parts are provided with longitudinal grooves on the circumference.
  • the basic element according to the invention can be used variably, for example with textile wrappings, inserts, etc. processed into a mattress or upholstery or directly is designed as a mattress or upholstery.
  • a very simple execution in terms of production technology consists in that the hollows or slots are bores that are extend across the basic element or mattress width. This are easy to manufacture, especially if the holes are through go through the side long sides of the basic element.
  • the Elongated holes in a row in several rows or in height staggered regularly over the length of the mattress become. But it is also possible to drill the holes irregularly, i.e. to be focused on in the basic element.
  • the basic element and the insert parts are preferably made of Plastic, such as polyurethane or latex.
  • Plastic such as polyurethane or latex.
  • the usage of natural products, such as wool, and their combination with Plastics is especially for the production of the basic element equally suitable.
  • the insert parts are as required or request can be interpreted in many ways. You can be massive made of foam, full latex or the like, or also hollow or be inflatable.
  • the mattress according to the invention is also suitable for heating elements, Radio speakers, etc. with the insert parts in the Bring mattress.
  • the mattress is particularly good for beds, seats, -chairs suitable. By dividing the mattress into areas the mattress can easily accommodate different levels of compression be folded or folded. So are on seats, chairs, etc. one-piece upholstery or mattresses can be used. At strong kink angles can be a particularly soft one at the kink Insert part used or the insert part even omitted become.
