Definitions

  • the invention relates to a cushion body, in particular a seat cushion for a motor vehicle, consisting of a spring body deformed in the loaded state and thereby permeable to air and moisture as well as an air-permeable covering material stretched thereon which is deposited with a buffer layer having a substantial content of cellulosic fibers.
  • DE-GM 75 03 063 refers to an upholstered body of the type specified above.
  • the spring body consists of a foam block that has through openings and into one more layered coating is encased.
  • the openings serve to improve the air circulation in the foam block and thus to dissipate moisture.
  • This effect is supported by the cover fabric, which has a layer of cellulose fibers and is able to absorb the moisture without saturation. If there is a large amount of moisture, however, this requires a considerable layer thickness and a long drying time between the periods of individual use, because the relative size of the exchange surfaces touching the openings is too small in relation to the surface of the cover fabric and because the openings contained in the openings are renewed Air volume is too slow.
  • Upholstered bodies of this type are therefore only conditionally suitable for long-term use.
  • the invention has for its object to show a cushion body which no longer has such disadvantages and which can be used continuously without the risk of the appearance of wet areas.
  • the spring body consists of fibers with hydrophilic properties and a titer of 3 to 50 dtex, which are combined to form a spatially oriented network and are glued at the crossing points, which when using natural and / or synthetic fibers a thickness of 5 to 20 mm has a density of 10 to 100 kg / m 3 and the basis weight of the buffer layer is 150 to 350 g / m 2 .
  • the spring body of the proposed cushion body has only a very small thickness of approximately 8 to 15 mm.
  • the preferred density is 50 kg / m 3.
  • the spring body consists of relatively coarse fibers with hydrophilic properties, which are combined to form a spatially oriented network and are glued at the crossing points.
  • the result is preferably in Area of greatest load, a local compression of 2 0 to 60% and a corresponding reduction in the volume of the cavity enclosed by the network. This reduction in volume is not constant in normal use, but changes depending on each change in the seat position or when using the cushion body as a seat cushion in a motor vehicle depending on each vehicle vibration initiated. In the network, therefore, a direction of the air flow is constantly reversed between the zones of different loads and parallel to the surface, which touches areas with different levels of moisture.
  • the network consists of fibers with hydrophilic properties, which lie against a buffer layer made of cellulose fibers and which, together with this, form a closed unit with regard to the absorption and desorption behavior.
  • the moisture absorbed by the buffer layer in a partial area is diverted before the occurrence of the saturation state into the fibers of the network and distributed over an exchange surface that is several times larger than the actually loaded surface.
  • the moisture can thus be more easily absorbed by the air flowing through the network and transported to other areas that are less heavily loaded.
  • Moisture is deposited here, preferably in turn in the fibers of the network, discharged into the buffer layer and evaporating over the surface during use. Moisture is no longer to be feared, even with long-term stress in an unchanged sitting position.
  • the basis weight of the buffer layer should be 150 to 350 g / m 2 . If the weight per unit area is lower, then an insufficient distribution of the moisture absorbed in a sub-area over as many fibers of the network as possible can result, but if the weight per unit area is higher, then an unsatisfactory desorption behavior when loaded by an average heavy, sedentary person in the unloaded areas, and in extreme conditions, for example when driving for a long time in summer, a moisture build-up can occur in the area of the polluted zone.
  • the dry feel of the surface can be promoted by applying a layer of hydrophobic fibers to the surface of the buffer layer.
  • This layer must be sufficiently permeable and must not significantly impair the absorption and desorption behavior of the buffer layer.
  • Woven and knitted fabrics, but also velor and terry fabrics with a basis weight of 100 to 500 g / m 2 made of polypropylene and / or polyester fibers have proven themselves, whereby any customary upholstery material can be used if the aforementioned requirements are met.
  • the usage properties of the proposed upholstery body depend to a large extent on a constant elasticity of the network.
  • the use of synthetically produced fibers made of hydrophobic materials is preferred, which have a surface coating made of a hydrophilic material.
  • Cross section of the coating made of a hydrophilic material is available. This cross-section is, however, quite sufficient in view of the large number of fibers combined in the network and in view of the fact that the possibility of moisture exchange both with regard to. is limited to the buffer layer as well as with regard to the air flowing past on the surface of the fibers.
  • practically the entire underside of the buffer layer and, in addition, the entire surface of each individual fiber of the spring body are available for the moisture exchange between the flowing air and the buffer layer.
  • the fibers can consist of metal and / or plastic. Corrosion-resistant materials are preferred for metals, in particular brass and corresponding steel grades. Of the plastics, those with low water absorption capacity are preferred, in particular polypropylene and polyester.
  • crimped fibers are preferably used.
  • the number of crimps per centimeter is 5 to 40.
  • the fibers are permanently glued to one another, so that there is no fear of the binding sites breaking up during use.
  • Chemically crosslinked binders are preferably used, for example based on rubber or synthetic resin.
  • the network within which the fibers are glued to one another can be a knitted fabric made of at least one endless thread.
  • the network consists of fibers combined according to a nonwoven technology, on the other hand, have the advantage of better fiber separation and, accordingly, a frequently improved moisture exchange.
  • the spring body 1 is connected to the top of the foam body 4. This consists of a mixture of the fibers defined below:
  • the binder deposited as a continuous layer on the surface of the fibers of the nonwoven and, after drying and subsequent crosslinking, caused them to bond to one another at the crossing points.
  • the proportion by weight of binder is 70%, the thickness of the spring body is 15 mm and the basis weight is 600 g / m.
  • a buffer layer made of a fleece obtained by wet means is arranged on the top of the spring body.
  • the fiber mixture consists of a mixture of the following fibers:
  • this binder After drying and subsequent crosslinking, this binder causes the fibers to bond to one another.
  • the proportion by weight of the binder in the buffer layer is 20%. With a weight per unit area of 250 g / m 2, it has a thickness of 1.5 mm.
  • the cover fabric 2 consists of a highly air-permeable knitted fabric made of polyamide fibers. This has a basis weight of 400g / m. It is cut and sewn in such a way that the unit consisting of foam body, spring body and buffer layer is enclosed on all sides.
