Opfindelsen angâr en elastisk brandsikker st0tte for den menneskelige krop eller dele deraf. Madrasser og lignende stotter for menneskekroppen, sâsom hynder og puder, ber udvise en god modstandsdygtighed ouer for 5 brand, og dette gælder specielt, nâr der er taie om stotter, som anvendes i offentlige indstitutioner, ek-sempelvis hospitaler, hvor faren for udbrud af brand er betragelig.The invention relates to a resilient fireproof support for the human body or parts thereof. Mattresses and similar supports for the human body, such as cushions and pillows, must exhibit good resistance to fire for 5, and this is especially true when there are many supports used in public institutions, such as hospitals where the risk of outbreaks of fire is considerable.
Man kan pâ simpel mâde indeslutte en elastisk stotteblok, 2Q sâsom en blok af skurn, i et hylster af brandhæmmende bomuldsvæv, men pâ denne mâde er det sandsynligt, at man opnâr en kropsstette, som er ubekvem at anvende.You can simply enclose an elastic support block, such as a block of scour, in a sheath of fire-retardant cotton fabric, but in this way it is likely to achieve a body support that is uncomfortable to use.
Den foreliggende opfindelse er sâledes resultatet af et udviklingsarbejde gennemfort med henblik pâ at finde 25 frem til en stettekonstruktion, som frembyder en til- strækkelig hoj grad af komfort og en tilfredsstillende hoj modstandsdygtighed imod brand.The present invention is thus the result of a development work carried out in order to find a support structure which provides a sufficiently high degree of comfort and satisfactory high resistance to fire.
Forholdsregler til opnâelse af brandsikring i polstrede artikler er foreslâet i GB patentskrift nr. 1 477 145, 2Q og et for vand uigennemtrængeligt madrasovertræk - frem- stillet ved at binde et strækbart tekstilvæv til et fleksibelt, for vand uigennemtrængeligt lag - er beskre-vet i GB offentliggorelsesskrift nr. 2 012 159. Disse skrifter omtaler imidlertid ikke de krav til stræknings-25 og restitutionsegenskaber i relation til deformerbarheden af en madras, en blok eller en anden stotte for den menneskelige krop, som er specificeret ifolge den foreliggende opfindelse. Skrifterne foreslâr heller ikke en kombination af disse strækningsegenskaber med krav til 30 opnâelse af tilfredsstillende brandsikring.Precautions for obtaining fire protection in padded articles are proposed in GB patent specification No. 1 477 145, 2Q and a water-impermeable mattress cover - made by bonding an extensible textile fabric to a flexible, water-impermeable layer - is described in GB Publication No. 2,001,159, however, does not disclose the requirements for stretching and restoring properties in relation to the deformability of a mattress, block or other support for the human body specified in accordance with the present invention. The scriptures also do not suggest a combination of these stretching characteristics with requirements to achieve satisfactory fire protection.
Med den foreliggende opfindelse tilvejebringes en elastisk stotte for den menneskelige krop eller dele heraf, hvilken stotte bestâr af en elastisk blok omsluttet af et fleksibelt brandsikkert hylster af strækbart vævet stof. DenThe present invention provides an elastic support for the human body or parts thereof, which consists of an elastic block enclosed by a flexible fireproof wrapper of stretchable woven fabric. The

2 elastiske kropsst0tte ifelge opfindelsen er ejendommelig ved, at i det mindste den del af hylsteret, der er bereg-net til at ligge imellem den elastiske blok og menneske-kroppen, har sâdanne strækningskarakteristika, at den 5 er i stand til at tilpasse sig efter den tilgrænsende overflade af blokken, nâr stotten under brugen deforme-res under menneskekroppens indvirkning, og at den er i stand til i tilstrækkelig grad at genvinde sin form efter en sâdan deformation, sâledes at man undgâr folder 10 eller rynker, efter at den elastiske blok er vendt til- bage til ikke-deformeret tilstand, at den elastiske blok er fuldstændigt omsluttet af et brandsikkert mate-riale, og at det strækbare stof er et lagdelt materiale med en strækbarhed pâ mindst 20 % i bredderetningen 15 og mindst 10 % i længderetningen malt pâ et Fryma Ex- tensiometer i overensstemmelse med britisk standard nr. 4294 under anvendelse af en belastning pâ 3 kg, idet lagdelingen er lokaliseret pâ den indre overflade af det brandsikre hylster, der grænser op til den elas-20 tiske blok.2 resilient body supports according to the invention are characterized in that at least the part of the sheath intended to lie between the resilient block and the human body has such stretching characteristics that it is able to adapt to the adjacent surface of the block as the support deforms during use under the action of the human body and is capable of sufficiently regaining its shape after such deformation to avoid folds 10 or wrinkles after the elastic block is reversed to non-deformed state, that the elastic block is completely enclosed by a fireproof material, and that the extensible fabric is a layered material having an extensibility of at least 20% in the width direction 15 and at least 10% in the longitudinal direction painted on a Fryma Extensiometer in accordance with British Standard No. 4294 using a load of 3 kg, the layering being located on the inner surface of the brass and other secure sleeves adjacent to the elastic block.
Den omhandlede elastiske kropstotte kan være en madras eller en del af en madras, eksempelvis en "biscuit" af den art, der benyttes som senge i eksempelvis beboelses-vogne, sammen med andre lignende "biscuits". Stotten kan 25 ogsâ eksempelvis være en hynde, som udgor en del af en stol eller en sofa, eller den kan være en pude eller hovedpude.The elastic body support in question may be a mattress or part of a mattress, for example a "biscuit" of the kind used as beds in, for example, carriages, together with other similar "biscuits". The support may also be, for example, a cushion forming part of a chair or sofa, or it may be a pillow or pillow.
Nâr den elastiske stotte ifalge opfindelsen har form af en madras, vil den elastiske natur af hylsteret 30 sikre, at dette noje folger de deformationer, som pâ grund af brugerens krop dannes i den ovre overflade af madrassen, hvorved man undgâr den lokaliserede for-ogelse af trykket pâ brugerens krop, som kan optræde, nâr sâdanne madrasser forsynes med mindre elastiske 35 hylstre. Den kendsgerning, at de foldede lag af hylsteret,When the elastic support according to the invention takes the form of a mattress, the elastic nature of the sheath 30 will ensure that this closely follows the deformations which, due to the user's body, form in the upper surface of the mattress, thereby avoiding the localized destruction. of the pressure on the user's body, which may occur when such mattresses are provided with less elastic casings. The fact that they folded layers of the sheath,

3 der omgiver en elastisk stette ifolge opfindelsen, befin-der sig pâ den indre overflade af hylsteret, reducerer ogsâ hylsterets tendens til at forskyde sig i forhold til stottens elastiske blok. I de tilfælde, hvor en 5 madras ifolge opfindelsen anvendes i længere tid, f.eks.3, which surrounds an elastic support according to the invention, which is located on the inner surface of the sheath, also reduces the tendency of the sheath to displace with respect to the elastic block of the support. In cases where a mattress according to the invention is used for a longer period, e.g.
af en invalid, har det vist sig, at hylsterets elastiske natur reducerer hyppigheden af liggesâr.by an invalid, it has been found that the elastic nature of the sheath reduces the frequency of bed sores.
Modstandsdygtigheden imod brand for et hylster anvendt i en stotte ifolge opfindelsen, eller for et væv an-10 vendt til fremstilling af hylsteret, er fortrinsvis af et sâdant omfang, at hylsteret eller vævet efter en enkelt vask i vand ved 71 °C vil opfylde kravene (uden rensningsproceduren ) svarende til type C, nâr de afpro-ves i overensstemmelse med del 2 i denbritiske stan-15 dard nr. 5867.The fire resistance of a casing used in a support according to the invention, or for a tissue used to make the casing, is preferably of such a size that the casing or fabric after a single wash in water at 71 ° C will meet the requirements (without the purification procedure) corresponding to type C when tested in accordance with Part 2 of British Standard No. 5867.
Man foretrækker, at det strækbare hylster til anvendelse i en kropsstette ifolge opfindelsen udviser en forlængelse pâ ikke under 30 % i bredden og ikke under 15 % i længde-retningen, nâr det afproves under de ovennævnte betingel-20 ser. Strækningen i bredderetningen kan være 35 % eller derover. Vævet behover ikke at indeholde elastomert garn.It is preferred that the stretchable sleeve for use in a body support according to the invention exhibits an extension of not less than 30% in width and not less than 15% in the longitudinal direction when tested under the above conditions. The width in the width direction can be 35% or more. The fabric does not need to contain elastomeric yarn.

Vævet behandles pâ en sâdan mâde,at cellulose-garnet, og dermed det samlede væv, bliver modstands-10 dygtigt over for brand. Fortrinsvis udgar cellulosegar net mindst 75?ô, og med fordel 80¾ eller derover af-vægten af vævet, og det har en vægt, efter behandling med et brandhæmmende middel, pâ mindst 250 g/m .The stretchable casing may be made of a fabric 5 comprising a flat polyamide yarn and a cellulose yarn, the fabric being knitted in a simple jersey structure so that the cellulose yarn is incorporated in the form of floral varnishes. The tissue is treated in such a way that the cellulose yarn, and thus the total tissue, becomes resistant to fire. Preferably, cellulose yarns comprise at least 75 oz, and advantageously 80¾ or more, of the tissue weight, and having a weight, after treatment with a fire retardant, of at least 250 g / m
Det omsluttende hylster kan bestâ af et lag, der skal 15 ligge an imod en avre statteoverflade pâ en elastisk blok, et lag, der skal ligge an imod en nedre statte-overflade pâ den elastiske blok, og et sidestykke, som er fastsyet til de avre og nedre lag, og hvis ender er syet sammen, eksempelvis ved hjarnet af den elastiske 20 blok. Alternativt kan det omsluttende hylster bestâ af stykker af et lagdelt materiale, der er fastklæbet pâ aile overfladerne af den elastiske blok. Som en yder-ligere mulighed kan hylsteret bestâ af et stykke af et plant materiale, der er fastklæbet til en underover-25 flade af den elastiske blok, og et yderligere materiale- stykke, der dækker den avre overflade og sideoverflader-ne af den elastiske blok. F. eks. kan et sâdant yderligere stykke af et lagdelt materiale bestâ af et avre lag, hvortil der er knyttet et yderligere lag, som hæn-30 ger ned fra kanterne og dækker sideoverfladerne af den elastiske blok, idet den nedre kant af dette yderligere lag er forsynet med et stykke af et elastisk materiale. Nâr dette yderligere stykke af det lagdel-te materiale anbringes pâ en tilsvarende formet elastiskThe enclosing sleeve may consist of a layer to abut against an outer stature surface of an elastic block, a layer to abut a lower stature surface of the elastic block, and a side piece secured to the lower and lower layers, and whose ends are sewn together, for example, at the corner of the elastic 20 block. Alternatively, the enclosing envelope may consist of pieces of a layered material adhered to all surfaces of the resilient block. As a further option, the sheath may consist of a piece of a flat material adhered to a bottom surface of the elastic block and an additional piece of material covering the outer surface and side surfaces of the elastic block. For example, such an additional piece of a layered material may consist of an outer layer to which is attached an additional layer which hangs down from the edges and covers the side surfaces of the elastic block, the lower edge thereof being layers are provided with a piece of elastic material. When this additional piece of the layered material is applied to a correspondingly shaped elastic

Med henblik pâ at lette udskiftningen af hylstrene 6 og 9, nâr disse skal renses eller repareres, er nvert af disse hylstre forsynet med en âbning, der fortrins-vis ligger langs den ene side af madrassen, og som kan 5 lukkes med en anordning, der let kan losnes, f. eks. en lynlâs.In order to facilitate the replacement of the casings 6 and 9 when they are to be cleaned or repaired, each of these casings is provided with an opening which is preferably located along one side of the mattress and which can be closed with a device. that can be easily detached, such as a zip.
Vævet, hvoraf hylsteret 6 er fremstillet, er et plant_ -.....skudstrikket lokkevæv. Dette væv er strikket pâ en ro- terende strikkemaskine i en konstruktion, der omfatter 10 - en grundstruktur af et fiadt nylongarn (polyamid) og_ florlokker af et cellulosegarn. Vævets florlokker er kun til stede pâ den ene af vævets overflader, nærmere bestemt den indre overflade af hylsteret 6. Florlak-kerne er sâledes i kontakt med polyurethanskummet fra 15 blokken 5, og resultatet er en reduceret tendens hos hyl steret 6 til at bevæge sig i relation til blokken 5.The tissue, of which the sheath 6 is made, is a plant-laced knit-knit fabric. This fabric is knitted on a rotary knitting machine in a construction comprising 10 - a basic structure of a threaded nylon (polyamide) and floral locks of a cellulose yarn. The floral loops of the tissue are present only on one of the surfaces of the tissue, more specifically the inner surface of the sheath 6. The floral core is thus in contact with the polyurethane foam from block 5, and the result is a reduced tendency of the sheath 6 to move. in relation to block 5.
Cellulosegarnet i vævet i hylsteret 6 er et spundet garn, der bestâr af 67 vægt-“ô bomuld og 33 vægt-% viscose. Vævet bestâr af 23 vægt-?ô nylon-grundgarn og 77 vægt-?i cel-20 lulose-florgarn, og vævet er gjort flammeresistent ved behandling med "Proban ® 210" forhandlet af Albright and Wilson Limited. Behandlingen til opnâelse af flamme-resistans samt selve vævet skal være af en sâdan beskaf-fenhed, at det behandlede væv efter en vask i vand ved 25 71 °C kan opfylde de krav (med undtagelse af rensnings- proceduren), der betegnes "type C", ved afprevning ifelge del 2 i britisk standard nr. 5867. En alternativ behandling til opnâelse af flammeresistens, som forer til en nodvendig grad af modstandsdygtighed, er en behand-The cellulose yarn in the tissue of the sheath 6 is a spun yarn consisting of 67 wt. Cotton and 33 wt.% Viscose. The fabric consists of 23 wt? Nylon base yarn and 77 wt.
