Opfindelsen angår et møbel med en rygstøtteanordning og som 5 angivet i krav l's indledning.The invention relates to a furniture with a backrest device and as stated in the preamble of claim 1.

Der kendes mange forskellige former for rygstøtteanordninger til sidde- eller liggemøbler, f.eks. ryghynder til en briks eller et andet i det væsentlige plant sidde- eller liggemøbel.Many different types of back support devices are known for sitting or reclining furniture, e.g. back cushions for a piece of furniture or other substantially flat sitting or reclining furniture.

10 De kendte rygstøtteanordninger kræver alle en eller anden form for fastgørelseselement eller afstivningselement, som i sin enkleste form kan udgøres af den væg, møblet er placeret op ad. I andre tilfælde anvendes bøjler, faste rygplader eller lignende som mekanisk støtte for et rygstøtteorgan, der f.eks.The known back support devices all require some form of fastener or stiffener, which in its simplest form can be constituted by the wall on which the furniture is placed. In other cases, shackles, fixed back plates or the like are used as mechanical support for a back support member, e.g.

15 er et betrukket skumgummistykke, en betrukket pude eller lignende .15 is an upholstered foam piece, cushion or the like.

Fra USA patent nr. 3.003.815 kendes en rygstøtteanordning af skumgummi og med en opbygning, der ligner den, der er angivet 20 i krav l's indledning. Rygstøtteanordningen er beregnet som et selvstændigt rygstøtte og kan vendes på forskellig vis. Skal rygstøteanordningen anvendes til en siddende person, anviser patentet dog, at den må vendes således, at en bagudvendende part hviler mod en væg eller lignende.From U.S. Patent No. 3,003,815, a foam rubber back support device is known and having a structure similar to that set forth in claim 1 of claim 1. The backrest device is intended as an independent backrest and can be reversed in various ways. However, if the backrest device is to be used for a seated person, the patent states that it must be reversed so that a rearward-facing member rests against a wall or the like.

Formålet med opfindelsen er at angive et møbel med en rygstøtteanordning, der er således indrettet, at rygstøtteanordningen kan placeres hvorsomhelst på en sidde- eller liggeflade og forblive, hvor den anbringes, helt uden anvendelse af yder-30 ligere afstivende midler, fastgørelsesmidler og lignende.SUMMARY OF THE INVENTION The object of the invention is to provide a furniture with a backrest device which is arranged so that the backrest device can be placed anywhere on a sitting or reclining surface and remain where it is placed, without the use of additional stiffeners, fasteners and the like.

Dette opnås ved at udforme møblet ifølge opfindelsen som angivet i krav l's kendetegnende del. Ligegyldigt hvor rygstøtteanordningen anbringes på fladen, forbliver den her, selvom én 35 eller flere personer bruger den som ryglæn med hele overkroppens vægt, fordi rygstøtteanordningens særlige form, herunder den fremadvendende flades hældning bagud og den herpå montere- DK 172663 Bl 2 de pude, og den særligt udformede underside, der i det væsentlige skal være plan, så størst mulig berøring med sidde- eller liggefladen opnås, får den til at "holde" fast i underlaget, så den ikke skrider, bl.a. fordi dens dimensioner er som angi-5 vet i kravet.This is achieved by designing the furniture according to the invention as set forth in the characterizing part of claim 1. No matter where the backrest device is placed on the surface, it stays here, even if one or more people use it as a backrest with the entire body weight, because the special shape of the backrest device, including the inclination of the forward face, and the cushion mounted thereon, and the specially designed underside, which must be essentially flat, so that maximum contact with the seating or lying surface is achieved, it causes it to "stick" to the substrate so that it does not slip, ia. because its dimensions are as specified in the claim.

Udtrykket "fremadvendende side" anvendes i ansøgningen som betegnelse for den side af rygstøtteanordningen, der ved sædvanlig brug vender mod en brugers ryg, d.v.s. den side man læ-10 ner sig op ad.The term "forward-facing" is used in the application to denote the side of the backrest device which, in normal use, faces a user's back, i.e. the side you lean on.

Hermed fås et møbel med utallige anvendelsesformål. Møblet kan f.eks. have en forholdsvis stor sidde- eller liggeflade og udgøre et sofaarrangement, man sidder i, eller et sofaarrange-15 ment, hvori man sidder eller halvt sidder og ligger, når man f.eks. ser TV eller video. Anvendes der flere rygstøtteanordninger på samme flade, kan de placeres helt individuelt efter brugernes ønske om siddestilling m.v. Møblet kan også have en mindre flade og være indrettet til kun én rygstøtteanordning 20 og dermed udgøre en individuelt indstillelig læne- eller liggestol. De frit flytbare rygstøtteanordninger kan, uden at dele overhovedet skal adskilles, mekanisk omkobles eller lignende, fjernes fra sidde- eller liggefladen, således at møblet momentant kan ændres fra et siddemøbel til et liggemøbel, 25 f.eks. en seng.This gives you a piece of furniture with countless uses. The furniture can, for example. have a relatively large sitting or reclining surface and constitute a sofa arrangement in which you sit, or a sofa arrangement in which you sit or half sit and lie down, for example. watching TV or video. If multiple backrest devices are used on the same surface, they can be placed completely individually according to the users' desire for a sitting position, etc. The furniture may also have a smaller surface and be arranged for only one backrest 20 and thus constitute an individually adjustable reclining or reclining chair. The freely movable backrest devices can be removed from the sitting or reclining surface without any part at all, separated, mechanically switched or the like, so that the furniture can be momentarily changed from a sitting furniture to a reclining furniture, e.g. a bed.

Trykket fra en person (eller flere personer), der læner sig op ad rygstøtteanordningen, vil på grund af anordningens skrå, bagudhældende udformning føres ned mod understøtningsfladen og 30 medvirker til at øge friktionen, så rygstøtteanordningen ikke kan skride på sidde- eller liggefladen.The pressure of a person (or more persons) leaning on the backrest device will, due to the inclined backward design of the device, be brought down towards the support surface and will help to increase the friction so that the backrest device cannot slip on the sitting or lying surface.

Desuden fås en øget siddekomfort samtidigt med, at pudens forankring til rygstøtteanordningen medvirker til, at trykket fra 35 en person, der læner sig mod puden og dermed mod rygstøtteanordningen, rettes mod understøtningsfladen. Pudens fastgørelse sikrer desuden, at den ikke flytter sig i forhold til rygstøt- 3 DK 172663 B1 teanordningen.In addition, increased seating comfort is obtained at the same time as the cushion's anchorage to the backrest device causes the pressure from a person leaning against the cushion and thus against the backrest device to be directed to the support surface. In addition, the cushion attachment ensures that it does not move relative to the backrest device.

Ved at udforme møblet Ifølge opfindelsen som angivet i krav 2's kendetegnende del kan man øge friktionsfladen mellem ryg-5 lænet bestående af rygstøtteanordningen og puden og sidde-eller liggefladen, hvilket øger valgmulighederne for betræk til de enkelte dele, således at et meget stort antal forskellige materialer kan anvendes, både til rygstøtteanordningens understøtningsflade og til sidde- eller liggefladen.By designing the furniture according to the invention as set forth in the characterizing part of claim 2, one can increase the friction surface between the backrest consisting of the backrest device and the cushion and the sitting or reclining surface, which increases the choice of covers for the individual parts, so that a very large number of different materials can be used both for the backrest support surface and for the seating or reclining surface.

Ved at udforme møblet ifølge opfindelsen som angivet i krav 3's kendetegnende del fås mulighed for utallige varianter i udformningen af ryglænet, både med hensyn til udseendet, sid-dekomforten, størrelsen o.s.v. Ved at udforme ryglænet på den-15 ne måde fås en udførelse, der endnu bedre "bider" sig fast i sidde- eller liggefladen. Vinklen mellem de to aflange dele er fortrinsvis 140e-160°, men kan til visse formål være 90®, f.eks. til brug i møbelhjørner.By designing the furniture according to the invention as defined in the characterizing part of claim 3, it is possible to countless variants in the design of the backrest, both in terms of appearance, seating comfort, size etc. By designing the backrest in this way, an embodiment is obtained which even better "bites" into the sitting or reclining surface. The angle between the two elongated portions is preferably 140e-160 °, but may for certain purposes be 90®, e.g. for use in furniture corners.

20 Opfindelsen forklares herefter nærmere under henvisning til tegn i ngen, hvor fig. 1 viser en udførelsesform for et møbel ifølge opfindelsen med to rygstøtteanordninger, set i perspektiv, 25 fig. 2 vi^er et ryglæn set skråt bagfra i en første udførelsesform, fig. 3 viser et ryglæn skråt bagfra i en anden udførelses-30 form, og fig. 4 viser et lodret, plant snit i ryglænet.The invention is then explained in more detail with reference to the drawings, in which fig. 1 is a perspective view of an embodiment of a furniture according to the invention with two backrest devices; FIG. Fig. 2 is a backrest, obliquely viewed from the rear in a first embodiment; 3 shows a backrest inclined from behind in another embodiment; and FIG. 4 shows a vertical, flat section of the backrest.

På tegningens fig. 1 er vist et sidde- eller liggemøbel 1 be-35 stående af en plan overdel 2 og en underpart 3, der f.eks. som vist kan udgøre et møbel på fire ben. På møblets i det væsentlige plane overflade 4 er der anbragt to rygstøtteanordninger DK 172663 B1 4 5, hver med en pude 8 anbragt foran, således at rygstøtteanordningen 5 sammen med puden udgør et ryglæn 14, der mere detaljeret er vist på tegningens fig. 2-4.In the drawing FIG. 1, a seating or reclining furniture 1 is shown consisting of a flat top 2 and a lower part 3, e.g. as shown, can be a four-legged piece of furniture. On the substantially planar surface 4 of the furniture there are arranged two backrest devices DK 172663 B1 4,5, each with a cushion 8 arranged in front, so that the backrest device 5 together with the cushion constitutes a backrest 14, which is shown in more detail in FIG. 2-4.

5 Hver rygstøtteanordning 6 omfatter en polsterkile 7, eksempl-vis med trekantet tværsnitsprofil, og som kan være fremstillet af eller polstret med et hvilket som helst materiale. I den viste udførelsesform er der anvendt polyuretanskumgummi; såkaldt koldskum. Skumkilerne 7 har en i det væsentlige plan un-10 derstøtningsflade 6, indrettet til at hvile på fladen 4, samt to opadgående sideflader 12 og 13, hvor fladen 12 er hældende bagud med en sådan hældning, at belastningen fra en siddende person giver en i det væsentlige nedadrettet belastning, så friktionen mellem rygstøtteanordningens 5 understøtningsflade 15 6 og overfladen 4 øges. Det er vigtigt, at fladerne 4 og 6 er 1 i tæt kontakt med hinanden, d.v.s., at fladen 6 også er rela tiv plan. Rygstøtteanordningerne 5 kan være sammensat af to kiler som vist på fig. 3, samlet langs knæklinien 9, så ryglænet får det viste vinkelpræg, der både øger siddekomforten og 1 20 friktionen mod fladen 4, men kan også være udformet helt ret linet, som vist på fig. 2. Hver skumkile omfatter en understøtningsflade 6, indrettet til at hvile på fladen 4, og to opadgående, indadhældende sideflader 12 og 13. Hvilken form bagsiden, d.v.s. fladen 13, skal have, er uafhængig af hæld-25 ningen af den fremadvendende side 12 og undersidens 6 kon struktion. Man er således frit stillet med hensyn hertil, -= hvilket givet mulighed for forskellige detailudformninger, f.eks. en lige, lodret ryg. Den viste form med trekantet tværsnitsprofil er dog materialebesparende.Each backrest device 6 comprises a padding wedge 7, for example with a triangular cross-sectional profile, which may be made of or padded with any material. In the embodiment shown, polyurethane foam rubber is used; so-called cold foam. The foam wedges 7 have a substantially planar support surface 6, adapted to rest on the surface 4, and two upwardly facing surfaces 12 and 13, the surface 12 being inclined rearwardly with a slope such that the load from a seated person gives a substantially downward loading so that the friction between the support surface 15 of the backrest device 6 and the surface 4 is increased. It is important that the surfaces 4 and 6 are 1 in close contact with each other, i.e., the surface 6 is also a relative plane. The backrest devices 5 may be composed of two wedges as shown in FIG. 3, assembled along the knuckle line 9, so that the backrest is given the angular appearance shown, which increases both the sitting comfort and the friction towards the surface 4, but can also be designed quite straight, as shown in fig. 2. Each foam wedge comprises a support surface 6, adapted to rest on the surface 4, and two upward, inwardly inclined side surfaces 12 and 13. What shape of the back side, i.e. the surface 13, must have, is independent of the inclination of the forward-facing side 12 and the construction of the underside 6. One is thus free to do so, - = which allowed for various retail designs, e.g. a straight, vertical back. However, the shape shown with a triangular cross-sectional profile is material saving.

5 30 v Rygstøtteanordningen 5 er selvfølgelig betrukket med passende materiale, det være sig stof, skind eller eventuelt kunstskind. Dog er understøtningsfladen 6 altid beklædt med et materiale, der giver stor friktion mod overfladen 4. Et sådant 35 materiale kan være skind, kunstskind, stof, d.v.s. i mange I; tilfælde det materiale, som sidefladerne 12 og 13 er beklædt ^ med. Understøtningsfladen 6 kan også være beklædt eller belagt 14 (1 5 DK 172663 B1 med særlige friktionsgivende plast- eller gummiarter, alt afhængigt af, hvilket materiale overfladen 4 er fremstillet af eller betrukket med.5 30 v The back support device 5 is of course covered with suitable material, be it fabric, leather or possibly artificial leather. However, the support surface 6 is always coated with a material which gives great friction to the surface 4. Such a material can be leather, artificial leather, fabric, e.g. in many I; in this case, the material with which the side surfaces 12 and 13 are coated. The support surface 6 may also be lined or coated 14 (1 DK 172663 B1) with special frictional plastic or rubber species, depending on the material the surface 4 is made of or coated with.

5 Foran rygstøtteanordningen (se fig. 1) er der anbragt en pude 8, der f.eks. kan være en sædvanlig rygpude stoppet med fjer, dun eller skumstoffyld af en eller anden art. Puden udgør den del af ryglænet 14, en person sædvanligvis vil læne sig op ad.5 A cushion 8 is arranged in front of the backrest device (see Fig. 1), e.g. can be a usual back cushion stuffed with feathers, down or foamy stuff of some kind. The pillow forms the part of the backrest 14 that a person will usually lean on.

10 Bagsiden af puden 8 er fortrinsvis fastgjort til rygstøtte-organet 5, se især fig. 4, således at puden altid står op ad rygstøtteanordningen og ikke kan glide herpå. Forbindelsen kan etableres ved hjælp af en langsgående lynlås, tryklåse, vel-crolåse eller lignende, eller være udført permanent ved sam-15 mensyning af stof- eller læderbetræk. Sammenhæftningen er vist foretaget langs den nederste kant på rygstøtteanordningen 5 og langs pudens bagside i hele længden, men der er selvfølgelig intet i vejen for, at samlingen udføres andre steder i den flade, hvor puden 8 rører sidefladen 12.10 The back side of the pad 8 is preferably attached to the backrest member 5, see in particular FIG. 4 so that the cushion always stands up against the backrest device and cannot slide on it. The connection can be established by means of a longitudinal zipper, pressure locks, velcro locks or the like, or be made permanently by the sewing of fabric or leather covers. The bonding is shown to be made along the lower edge of the backrest device 5 and along the back of the pillow throughout its length, but of course there is nothing in the way of the joint being performed elsewhere in the surface where the pillow 8 touches the side surface 12.

For at øge friktionen mellem ryglænet og fladen 4 kan undersiden 10 af puden 8 være forsynet med et friktionsgivende lag eller materiale ligesom ovenfor forklaret om understøtningsfladen 6, hvis pudens betræk i sig selv ikke yder tilstrække-25 lig friktion.In order to increase the friction between the backrest and the surface 4, the underside 10 of the pad 8 may be provided with a friction-giving layer or material, as explained above, on the support surface 6, if the cover of the pad does not in itself provide sufficient friction.

Rygstøtteanordningens højde h, se fig. 4, bør være mindre end summen af dybderne p + b for puden 8 og rygstøtteanordningens 5 grundflader, så tilstrækkelig friktion altid opnås, og man 30 undgår, at ryglænet kan kæntre bagover.The height h of the backrest device, see fig. 4, should be less than the sum of the depths p + b of the pad 8 and the back surfaces of the backrest 5 so that sufficient friction is always obtained and 30 is prevented from the backrest tapping.

Forsøg har vist, at hvis fladen 4 er af relativt glat skind, og hvis understøtningsfladen 6 er beklædt med et skridlag af friktionsgivende materiale, f.eks. polyuretanbelagt eller gum-35 mibelagt stof, og hvis puden 8 er betrukket med relativt glat skind, f.eks. det samme skind, som fladen 4 er betrukket med, bliver ryglænet 14, d.v.s. rygstøtteanordningen 4 med puden 8, DK 172663 B1 6 stående fast på overfladen.Tests have shown that if the surface 4 is of relatively smooth skin and if the support surface 6 is lined with a skid layer of frictional material, e.g. polyurethane-coated or rubber-coated fabric, and if the pad 8 is covered with relatively smooth skin, e.g. the same skin with which the surface 4 is covered becomes the backrest 14, i.e. the back support device 4 with the cushion 8, standing firmly on the surface.
