Definitions

  • the invention initially relates to a cushion, mat, mattress or the like (hereinafter referred to as "cushion"), consisting of an elastic insert and a covering completely surrounding this insert made of an air-impermeable material, and an air seal of the cushion interior (preamble of the claim 1).
  • Such cushions are known in principle, for example, from DE-PS 99773. They are also known in the form of a so-called ring pillow.
  • the airtight closure takes place with the aid of a valve which is inserted into the casing and can be opened or closed as desired. When the valve is open, the cushion can be compressed by a certain amount, the corresponding portion of the air in the cushion being pressed out by the opened valve.
  • the invention intends to design a cushion according to the preamble of claim 1 cited at the outset so that, while maintaining its functional advantages, simplification is achieved both in terms of manufacture and handling.
  • the insert is compressed over a substantial area of its surface to a fraction of the thickness that it has in the unloaded state, that the covering is essentially against the insert and without Use of a valve that forms the air seal of the interior of the cushion against the atmospheric external pressure solely with the material on all sides (characterizing part of claim 1).
  • the cushion according to the invention has a partially compressed insert that forms a relatively hard, but within certain limits still resilient seat shell. In many cases, this is not only advantageous but also desirable, in which a merely compressible foam insert with any coating, as described, for example, in DE-OS 34 44 459, would be too soft and flexible.
  • a further embodiment of the invention is the subject of claim 3. This allows, on the one hand, if desired, a cooling effect to be achieved with such a cushion. This also prevents or at least reduces the risk of so-called bedsores lying on a cushion or sitting for a long time. Another advantage is that the specific weight of such a cushion, which is partially filled with a flowable medium (e.g. water or gel), is greater, so that it does not float as strongly when used in a bathtub, if necessary. even drops.
  • a flowable medium e.g. water or gel
  • Claims 4 and 5 contain design options for the insert.
  • the invention further relates to a method for producing a cushion according to one of the preceding claims, according to which the insert is first provided with the only partially closed covering, then the insert is compressed in the desired manner and by the desired amount and then the envelope is sealed airtight while maintaining this compression.
  • the cushion consists of a partially compressed elastic insert 1 and an all-round airtight covering 2 surrounding this insert, which essentially bears against the insert.
  • These can be two webs 2 ', 2 ⁇ , which are connected to one another in an airtight manner along their circumferential edges 2, preferably welded.
  • the manufacture of such a cushion is very simple. First take the non-compressed insert 1 (see Fig. 3) and surround it with the two wrapping halves 2 ', 2,, one side, for example the numbered 4 in Fig. 3 and the right side there is not yet airtight . Then the compression takes place the insert 1, for example according to a preferred embodiment of the invention by about 60 percent, and at the same time welding the edges 3 located on the side 4.
  • the thickness of the insert 1 thus decreases from the amount a of the uncompressed state and in the compressed area the smaller amount b (see Fig. 1).
  • the insert of this cushion (see FIGS. 1, 2) is and remains compressed accordingly, which is also indicated in the drawing by the hatching which is denser than that in FIG. 3. It forms a kind of seat shell, which is relatively firm and resistant, ie only has a low elasticity. There is the further advantage that the shape of this seat shell once achieved can be easily changed by appropriate pressure on the surface of the upper envelope half 2 '. However, a re-expansion of the insert 1 to the thickness a according to FIG. 3 is not possible, since with the compression of the insert 1 to the thickness b according to FIG.
  • a cushion according to the invention can also be designed as a mattress and the like.
  • the interior of the cushion can also be partially filled with a liquid, preferably water (not shown).
  • a liquid preferably water (not shown).
  • the airtight cover prevents the liquid from escaping.
  • the elastic insert 1 can be an elastic foam, but also another elastically compressible material, e.g. Rubber fibers.
