Abstract

The item of furniture for seating has a seat support which runs essentially horizontally with a front edge, which in use is positioned near the knee of a user on the under side of the thigh of the user. The seat support is composed of four side surfaces, which support the thigh of a user and the lowermost part of their bottom. The seat support has also two rearmost seat surfaces which support an uppermost part of the bottom of a user. When a user sits on the seat, a correct lumbar swaying movement is possible because of the reciprocal angles between the side surfaces. The item of furniture may also be provided with a back support.

Stolesædet er baseret på ergonomiske betragtninger og er udformet for dels at tilfredsstille ergonomiske behov hos brugeren og undgå risiko for trykbelastninger og dermed risiko for siddesår hos handicappede personer, som er bevægelseshæmmede eller lammede. Stolesædet skal samtidig være indrettet for en let og enkel produktion. : 15The chair seat is based on ergonomic considerations and is designed to partly satisfy the user's ergonomic needs and avoid the risk of pressure loads and thus the risk of sitting wounds in disabled people who are disabled or paralyzed. The chair seat must also be designed for easy and simple production. : 15

Der kendes således mange forskellige typer sædeunderstøtninger, som er udformet med henblik på at skabe den bedst mulige brugerkomfort og den bedst mulige understøtning for brugeren. Der kendes således siddemøbler, som er tilvejebragt alene med sædeunderstøtning eller som tillige er forsynet med en rygunderstøtning. For at skabe 20 en fornøden understøtning, og stabilitet for brugeren er sædeunderstøtningen almindeligvis udformet med en anatomisk afrundet tilpasning, som er afpasset efter kroppens former.Thus, many different types of seat supports are known, which are designed in order to create the best possible user comfort and the best possible support for the user. Thus, seating furniture is known which is provided solely with seat support or which is also provided with a back support. In order to create a necessary support and stability for the user, the seat support is usually designed with an anatomically rounded fit which is adapted to the shapes of the body.

Det er almindeligt kendt, at mange siddemøbler, som benyttes i køretøjer, kørestole 25 eller til arbejdsbrug, bør have en stabiliserende effekt for brugeren for at undgå unødige belastninger. De fleste sædeunderstøtninger har imidlertid været ufordelagtige, da det har været nødvendigt at foretage individuel justering til hver enkel bruger. Endvidere har de været ufordelagtige, idet der til trods for bestræbelser på at opnå en sidde-komfort alligevel har været gener forbundet med at sidde i disse stole. Brugere, som 30 sidder lang tid i sådanne stole, har således oplevet træthedsfomemmelser. Endvidere har brugere, som er fysisk handicappede, og som har vanskeligt ved at bevæge sig samt brugere der er lammede, haft risiko for at få siddesår ved længere tids ophold i t· 2 DK 173053 B1 siddemøbler. Sådanne siddesår eller fysiske gener er forekommet, selvom siddemøblet har været tilpasset den enkelte bruger.It is well known that many seating furniture used in vehicles, wheelchairs 25 or for work use should have a stabilizing effect on the user to avoid unnecessary strain. However, most seat supports have been disadvantageous as it has been necessary to make individual adjustment for each individual user. Furthermore, they have been disadvantageous in that, despite efforts to achieve a sitting comfort, there have nevertheless been inconveniences associated with sitting in these chairs. Users who sit in such chairs for a long time have thus experienced feelings of fatigue. Furthermore, users who are physically handicapped and who have difficulty moving and users who are paralyzed have had a risk of getting seat wounds during prolonged stays in t · 2 DK 173053 B1 seating furniture. Such seat wounds or physical inconveniences have occurred even though the seat furniture has been adapted to the individual user.

Til grund for den foreliggende opfindelse har der været et ønske om at tilvejebringe en S stol med en højere siddekomfort, og som gør det muligt at etablere et siddemøbel, som har en siddeunderstøtning og eventuelt også en rygunderstøtning, som kan benyttes af forskellige personer uden at kræve individuel tilpasning, og som tillige giver en sikker og anatomisk korrekt understøtning.Based on the present invention, there has been a desire to provide an S chair with a higher seating comfort, and which makes it possible to establish a seating piece of furniture which has a seating support and possibly also a back support which can be used by different persons without require individual adaptation, and which also provides a secure and anatomically correct support.

10 Ifølge den foreliggende opfmdelse opnås dette med et siddemøbel af den indledningsvis nævnte type, som er særpræget ved, at sædeunderstøtningen er dannet af fire sædeflader, der er indrettet for at understøtte brugerens lår og en nederste del af brugerens balder henholdsvis den bageste del af brugerens balder, at nævnte sædeflader er tilvejebragt to og to symmetrisk på hver side af et lodret midtplan gennem sædeun-15 derstøtningen, at sædeflademe parvis er dannet med en indbyrdes vinkel mellem 140 og 160°, fortrinsvis 150°, således som målt i et plan vinkelret på sædeflademe, og at de to bageste sædeflader er tilvejebragt med en bagud og opefter rettet hældning mellem 110 og 130®, fortrinsvis 120®, i forhold til et plan for de forreste sædeflader.According to the present invention, this is achieved with a seating piece of the type mentioned in the introduction, which is characterized in that the seat support is formed by four seat surfaces which are arranged to support the user's thighs and a lower part of the user's buttocks and the rear part of the user's buttocks, said seat surfaces being provided two and two symmetrically on each side of a vertical center plane through the seat support, that the seat surfaces are formed in pairs at a mutual angle between 140 and 160 °, preferably 150 °, as measured in a plane perpendicular on the seat surfaces, and that the two rear seat surfaces are provided with a rearward and upwardly directed inclination between 110 and 130®, preferably 120®, relative to a plane of the front seat surfaces.

20 Et siddemøbel af ovennævnte type kan karakteriseret som en taburet eller et siddemøbel, som alene omfatter et sæde.A seat piece of furniture of the above type may be characterized as a stool or a seat piece of furniture which comprises only one seat.

Ifølge et andet aspekt ved den foreliggende opfmdelse opfyldes det ønskede formål i et siddemøbel af den type, som er forsynet med en iygunderstøtning i en udformning, 25 som er særpræget ved, at sædeunderstøtningen er dannet af to sædeflader, der er indrettet for at understøtte brugerens lår og en nederste del af brugerens balder, at nævnte sædeflader er tilvejebragt symmetrisk på hver side af et lodret midtplan gennem sædeunderstøtningen, at sædeflademe er dannet med en indbyrdes vinkel mellem 140® og 160®, fortrinsvis 150®, således som målt i et plan vinkelret på sædeflademe, og at to 30 bageste sædeflader er tilvejebragt i rygunderstøtningen og er indrettet for at understøtte en øverste del af brugerens balder/brugerens lænd, idet de er dannet med en ftemad 3 DK 173053 B1 og opefter rettet hældning mellem 75® og 85°, fortrinsvis 80®, i forhold til et plan for de forreste sædeflader.According to another aspect of the present invention, the desired object is fulfilled in a seating piece of furniture of the type provided with a reclining support in a design which is characterized in that the seat support is formed by two seat surfaces arranged to support the user's thighs and a lower part of the user's buttocks, said seat surfaces being provided symmetrically on each side of a vertical center plane through the seat support, that the seat surfaces are formed at a mutual angle between 140® and 160®, preferably 150®, as measured in a plane perpendicular to the seat surfaces, and that two rear seat surfaces are provided in the back support and are arranged to support an upper part of the user's buttocks / user's loins, being formed with a fat food 3 DK 173053 B1 and upwards directed inclination between 75® and 85 °, preferably 80®, relative to a plane of the front seat surfaces.

Med et siddemøbel af denne type er dannet en stol, som omfatter sidde- og ryglæn. En 5 sådan stol kan især være anvendelig til kørestole, hvor ryggen skal kunne svinge bagud til en stort set vandret stilling i forlængelse af sædeunderstøtningen. Denne svingning kan udføres på forskellige måder. Ved nedfældningen af ryglænet vil der med en udformning, som angivet ovenfor, ikke opstå ubehagelige tiykbelastning på lænden under rygunderstøtningen svingende bagud.With a seating piece of furniture of this type, a chair is formed, which comprises a sitting and backrest. Such a chair can be particularly useful for wheelchairs, where the back must be able to swing backwards to a substantially horizontal position in extension of the seat support. This oscillation can be performed in different ways. When the backrest is folded down, with a design as stated above, there will be no unpleasant tensile load on the lumbar during the backrest swinging backwards.

Efter lang tids arbejde har det overraskende vist sig, at en sædeunderstøtning, der er udformet på denne måde, giver en behagelig understøtning og tillige giver en stabilitet, således at man kan undgå slingrekanter på stolens sædeunderstøtning. Siddemøbler er især velegnet til brug i kørestol for fysisk handicappede og lammede personer, -15 idet der opnås en god stabilitet i stolen samtidig med, at der opnås en anatomisk korrekt understøtning med meget lille risiko for tiykskader.After a long time of work, it has surprisingly been found that a seat support designed in this way provides a comfortable support and also provides a stability, so that one can avoid swaying edges on the seat support of the chair. Seating is particularly suitable for use in wheelchairs for the physically handicapped and paralyzed persons, -15 as good stability is achieved in the chair at the same time as anatomically correct support is obtained with very little risk of tyke injuries.

Det har vist sig muligt at fremstille sædeunderstøtningen med en udformning, som er meget lidt afhængig af polstringen på de flader, som danner sædeunderstøtning og 20 eventuel rygunderstøtning.It has been found possible to manufacture the seat support with a design which is very little dependent on the upholstery on the surfaces which form the seat support and any back support.

Ved at udforme sædeunderstøtningen med fire sædeflader, som defineret ovenfor, bliver det muligt at etablere en understøtning på brugerens kødfulde del af låret ved hjælp af de forreste siddeflader, medens der etableres en understøtning på den kødful-25 de bageste del af brugerens baller ved hjælp af de to bageste sædeflader. Når sædefla-deme er etableret med en indbyrdes vinkel indenfor det angivne interval, har det vist sig, at voksne brugere, som kan siges at være indenfor et bredt spekter af normal størrelse, vil sidde med en sikker understøtning, hvor der ikke vil være tendens til at glide på siddemøblet. Endvidere har det også vist sig, at der med vinkler indenfor det angiv-30 ne interval ikke vil opnås en ubehagelig effekt ved sammenklemning af lår, således som brugere kan opleve i traditionelle sædeunderstøtninger, hvor der er tilvejebragt slingrekanter, som presser mod ydersiden af brugerens lir.By designing the seat support with four seat surfaces, as defined above, it becomes possible to establish a support on the user's meaty part of the thigh by means of the front seating surfaces, while a support is established on the meaty rear part of the user's balls by means of of the two rear seat surfaces. When the seat surfaces are established at a mutual angle within the specified range, it has been found that adult users who can be said to be within a wide range of normal size will sit with a secure support where there will be no tendency to slide on the seating furniture. Furthermore, it has also been found that with angles within the specified range, an unpleasant effect will not be obtained when squeezing thighs, as users may experience in traditional seat supports where sling edges are provided which press against the outside of the user's. lir.

Med en udformning af sædeunderstøtningen i overensstemmelse med opfindelsen er det også muligt at reducere risikoen for siddesår eller andre fysiske skader på personer, som er bevægelseshæmmede eller lammede. Idet understøtningen optræder på de S kødfulde dele af lårenes og ballemes bagside, vil der ikke optræde trykbelastninger ved de dele af brugerens legeme, hvor knogler ligger nær overfladen. Således vil der ikke optræde trykbelastninger på undersiden af brugerens baller, som normalt kan give anledning til tryksår. Ligeledes vil der ikke optræde nogen trykpåvirkning ved brugerens haleben. Tværtimod vil dette befinde sig i en position stort set uden kontakt med 10 sædeunderstøtningen i en placering ud for grænsefladen mellem to tilstødende sædeflader.With a design of the seat support in accordance with the invention, it is also possible to reduce the risk of seat wounds or other physical injuries to persons who are disabled or paralyzed. As the support appears on the S fleshy parts of the back of the thighs and buttocks, no pressure loads will occur at the parts of the user's body where bones are close to the surface. Thus, no pressure loads will occur on the underside of the user's bales, which can normally give rise to pressure ulcers. Likewise, there will be no pressure effect on the user's tailbone. On the contrary, it will be in a position substantially without contact with the seat support in a location off the interface between two adjacent seats.

Sædefladen, som støtter mod bagsiden af brugerens baller, kan være tilvejebragt som en integreret del med de forreste sædeflader. I denne udførelsesform kan sædeunder- : ' 15 støtningen være tilvejebragt som almindeligt stolesæde uden ryglæn. Alternativt har det også vist sig muligt at tilvejebringe de to bageste sædeflader sammen med støtte-fladerne i rygunderstøtningen. I denne udførelsesform vil den bageste del af sædeunderstøtningen således kunne siges at udgøre en del af ryglæn, som er tilvejebragt på en stol. I en sådan udførelsesform vil et sådant siddemøbels stolesæde alene være dannet 20 af de to fojreste sædeflader.The seat surface, which abuts the back of the user's bales, may be provided as an integral part with the front seat surfaces. In this embodiment, the seat support may be provided as an ordinary chair seat without a backrest. Alternatively, it has also been found possible to provide the two rear seat surfaces together with the support surfaces of the backrest. In this embodiment, the rear part of the seat support can thus be said to form part of a backrest which is provided on a chair. In such an embodiment, the chair seat of such a seating piece of furniture will only be formed 20 of the two furthest seat surfaces.

Siddemøbler kan således være tilvejebragt med en udformning uden ryglæn eller i en udformning med ryglæn. Såfremt siddemøbler er udformet med et ryglæn, som er svingbart lejret i forhold til selve sædedelen, foretrækkes det, at den bageste sædeflade 25 er forbundet med rygunderstøtningens støtteflader. Dette er for eksempel tilfældet i kørestole, hvor ryglænet er nedfældelig, idet det svinges bagud i forhold til sædeunderstøtningen. Det har således vist sig at være den ergonomiske bedste løsning, som giver mindst ulemper for brugeren at tilvejebringe den bageste sædeflade på ryglæn og lade den bageste sædeflade svinge nedefter sammen med rygflademe i ryglænet. Her-30 ved kan der opnås en tilbagevipning ved en kurveformet svingningsbevægelse af ryglænet, som foretages på en sådan måde, at der ikke optræder strækning eller forkortning af afstanden mellem understøtningspunkteme, hvor brugeren er i kontakt 5 DK 173053 B1 med siddemøblet. Det bliver således muligt at få en såkaldt neutral nedfældning af ryggen, hvilket er særligt væsentligt i kørestole for fysisk handicappede personer. Ved en sådan nedfældning af ryglænet vil der ikke optræde en fysisk belastning på brugeren, når de bageste sædeflader svinges nedefter sammen med ryglænet.Seating can thus be provided with a design without backrest or in a design with backrest. If seating furniture is designed with a backrest which is pivotally mounted relative to the seat part itself, it is preferred that the rear seat surface 25 is connected to the support surfaces of the backrest. This is the case, for example, in wheelchairs, where the backrest is fold-down, as it swings backwards in relation to the seat support. Thus, it has been found to be the ergonomic best solution which provides the least inconvenience to the user to provide the rear seat surface on the backrest and allow the rear seat surface to pivot downwards together with the back surfaces of the backrest. Hereby a recoil can be obtained by a curved oscillating movement of the backrest, which is made in such a way that no stretching or shortening of the distance between the support points occurs, where the user is in contact with the seating furniture 5 DK 173053 B1. It will thus be possible to have a so-called neutral lowering of the back, which is particularly important in wheelchairs for physically disabled people. With such a lowering of the backrest, no physical load will occur on the user when the rear seat surfaces are swung downwards together with the backrest.

5 Når siddemøblet ifølge opfindelsen er forsynet med en rygunderstøtning, har det vist sig, at vinklen mellem rygflademe, således som målt i et stort set vandret plan eller et plan vinkelret på rygflademe, ligeledes skal være mellem 140 og 160°. Herved vil brugerens rygrad ikke komme i kontakt med ryglænet, og der vil derfor ikke være an-10 ledning til trykskader. Brugeren vil derimod være i kontakt med rygunderstøtningen via de kødfulde dele bagerst på ryggen.When the seating furniture according to the invention is provided with a back support, it has been found that the angle between the back surfaces, as measured in a substantially horizontal plane or a plane perpendicular to the back surfaces, must also be between 140 and 160 °. As a result, the user's spine will not come into contact with the backrest, and there will therefore be no reason for pressure injuries. The user, on the other hand, will be in contact with the back support via the fleshy parts at the back.

Det foretrækkes, at sædeunderstøtningen er tilvejebragt for at kunne vinkelstilles i forhold til en ramme for siddemøblet. Når der kan etableres en sådan vinkelstilling : 15 foretrækkes det også, at den er tilvejebragt, således at de forreste sædeflader kan tilvejebringes med en hældning, som er rettet bagud og nedefter, og som har en vinkel mellem ca. 2 og 10°. En sådan vinkel vil fortrinsvis være relativ begrænset og vil især være i størrelsesordenen 2-5°, hvorved der opnås en komfortabel siddestilling for brugeren.It is preferred that the seat support be provided to be able to be angled relative to a frame for the seating furniture. When such an angular position can be established: it is also preferred that it is provided so that the front seat surfaces can be provided with an inclination which is directed backwards and downwards and which has an angle between approx. 2 and 10 °. Such an angle will preferably be relatively limited and will in particular be of the order of 2-5 °, whereby a comfortable sitting position is obtained for the user.

Et siddemøbel ifølge opfindelsen vil kunne tilvejebringe en polstring af sæde- og rygunderstøtningen ved hjælp af fleksible eftergive! ige pudeorganer. En sådan polstring kan være etableret af almindelig kendte principper. Det vil således sige, at der kan tilvejebringes en polstring med en vis tykkelse, som er anbragt ovenpå stort set 25 stive understøtningsflader, som befinder sig indeni sæde- og rygunderstøtningens polstringer.A seating piece according to the invention will be able to provide an upholstery of the seat and back support by means of flexible resins! cushion organs. Such padding may be established by commonly known principles. That is, a padding of a certain thickness can be provided which is placed on top of substantially 25 rigid support surfaces which are located inside the padding of the seat and backrest.

Alternativt kan siddemøblet være opbygget af pudeorganer, der er tilvejebragt i flere lag. I en sådan konstruktion vil mindst et lag, fortrinsvis det lag som er tilvejebragt 30 længst væk for brugeren, være tilvejebragt med en stort set ensartet tykkelse over hele udstrækningen. Hvert af understøtningens støtteflader vil derefter være defineret med de ønskede vinkler ved indskydelse af mindst et yderligere lag, som er dannet af kile- i 3 i , DK 173053 B1Alternatively, the seating furniture may be constructed of cushion members provided in several layers. In such a construction, at least one layer, preferably the layer provided furthest from the user, will be provided with a substantially uniform thickness over the entire extent. Each of the support surfaces of the support will then be defined by the desired angles by inserting at least one further layer formed by wedges in 3 i, DK 173053 B1

stykker. Ved at opbygge siddemøblerne efter et sådant princip er det relativt let at foretage de få justeringer, som kan være påkrævet for at foretage en individuel tilpasning indenfor de områder og indbyrdes vinkler, som optræder mellem de enkelte ryg-og sædeflader.pieces. By constructing the seating furniture according to such a principle, it is relatively easy to make the few adjustments that may be required to make an individual adjustment within the areas and mutual angles that occur between the individual back and seat surfaces.

Ved fremstilling af siddemøbel i flere lag kan der fordelagtigt anvendes lag med forskellig elastisk eftergivelighed. Det er således muligt at kombinere almindelige lag med traditionel skummaterialer med andre lag, der er fremstillet af viskoelastiske skummaterialer.When manufacturing seating furniture in several layers, layers with different elastic resilience can be advantageously used. It is thus possible to combine ordinary layers of traditional foam materials with other layers made of viscoelastic foam materials.

Siddemøbler vil fortrinsvis kunne anvendes i forbindelse med kørestole. Imidlertid vil siddemøblet på grund af sin komfort ligeledes kunne anvendes i traditionelle lænestole, arbejdsstole, hvilestole, stole i behandlingsklinikker mv.Seating can preferably be used in connection with wheelchairs. However, due to its comfort, the seating furniture can also be used in traditional armchairs, work chairs, recliners, chairs in treatment clinics, etc.

15 £t siddemøbel ifølge opfindelsen kan, som nævnt, ligeledes være udformet uden ryglæn. I en sådan udførelsesform kan siddemøblet være udformet som en traditionel taburet eller vipbare taburetter, hvor brugeren hviler knæene på en støtteflade, der er placeret foran stolesædet med henblik på at få en siddestilling med konekt lændesvaj.As mentioned, a piece of seating furniture according to the invention can also be designed without a backrest. In such an embodiment, the seating furniture may be designed as a traditional stool or tiltable stools, where the user rests the knees on a support surface located in front of the chair seat in order to have a sitting position with a conical lumbar sway.

20 Opfindelsen vil herefter blive forklaret nærmere under henvisning til den medfølgende skematiske tegning, hvor fig. 1 viser et perspektivisk billede af et siddemøbel ifølge et første aspekt ved opfindelsen, 25 fig. 2 viser et sidebillede til illustration af det i fig. 1 viste siddemøbel i brug, fig. 3 viser et perspektivisk billede af et siddemøbel ifølge det andet aspekt ved opfindelsen, fig. 4 viser et sidebillede til illustration af det i fig. 3 viste siddemøbel i 30 brug, fig. 5-7 viser tre sidebilleder set fra forskellige sider til illustration af støtte fladen i et siddemøbel ifølge et første aspekt ved opfindelsen, 7 DK 173053 B1 fig. 8-10 viser sidebilleder set fra forskellige sider af en rygunderstøtning til brug i et siddemøbel ifølge et andet aspekt ifølge opfindelsen, og fig. 11-13 sidebilleder set fra forskellige sider til illustration af en sædeunderstøtning til brug i et siddemøbel ifølge et andet aspekt ved opfin-5 delsen sammen med den i fig. 8-10 viste rygunderstøtning.The invention will now be explained in more detail with reference to the accompanying schematic drawing, in which fig. 1 shows a perspective view of a seating piece of furniture according to a first aspect of the invention, fig. 2 shows a side view for illustration of the device shown in fig. 1 in use, fig. Fig. 3 shows a perspective view of a seating piece of furniture according to the second aspect of the invention; 4 shows a side view for illustration of the device shown in fig. 3 in use, fig. 5-7 show three side views seen from different sides to illustrate the support surface in a seating piece of furniture according to a first aspect of the invention, 7 DK 173053 B1 fig. 8-10 show side views seen from different sides of a back support for use in a seating piece of furniture according to another aspect according to the invention, and fig. 11-13 side views seen from different sides to illustrate a seat support for use in a seating piece of furniture according to another aspect of the invention together with the one in fig. 8-10 showed back support.

Det bemærkes, at figurerne viser den principielle opbygning af støtteflademe i siddemøblet. I praksis vil siddemøblet forsynes med polstringer, som dækker de viste fla-, der. Imidlertid bemærkes det, at siddemøblet ifølge opfindelsen er opbygget med stort 10 set plane flader, der uanset om de er polstrede adskiller sig markant fra traditionelle siddemøbler, hvor understøtningsflademe er dannet med krumninger og kurver, som er tilpasset efter brugeren.It is noted that the figures show the basic structure of the support surfaces in the seating furniture. In practice, the seating furniture will be provided with upholstery which covers the surfaces shown. However, it is noted that the seating furniture according to the invention is constructed with substantially flat surfaces which, whether upholstered or not, differ markedly from traditional seating furniture, where the support surfaces are formed with curves and curves which are adapted to the user.

I tegningens forskellige figurer vil tilsvarende eller identiske elementer blive betegnet -IS med samme henvisningsbetegnelse. Der vil derfor ikke gives en specifik forklaring i forbindelse med hver enkelt figur.In the various figures of the drawing, corresponding or identical elements will be denoted -IS by the same reference numeral. Therefore, no specific explanation will be given in connection with each individual figure.

Fig. 1 og 2 viser et siddemøbel i form af en sædeunderstøtning 1. Sædeunderstøtningen 1 er i den viste form udformet i et første aspekt ifølge opfindelsen. Det vil sige en 20 udformning, hvor den vil anvendes uden rygunderstøtning. En bruger 2 er således placeret i sædeunderstøtningen, som er orienteret stort set vandret. Sædeunderstøtningen har en forreste kant 3, der er beregnet til i brug at være placeret nær brugerens knæ 4 ved undersiden af brugerens lår 5.FIG. 1 and 2 show a seating piece of furniture in the form of a seat support 1. The seat support 1 is in the form shown formed in a first aspect according to the invention. That is, a design where it will be used without back support. A user 2 is thus located in the seat support, which is oriented substantially horizontally. The seat support has a front edge 3 which, in use, is intended to be located near the user's knee 4 at the underside of the user's thigh 5.

25 Sædeunderstøtningen er dannet af fire sædeflader. Der er tilvejebragt to forreste sædeflader 6, der er beregnet til at understøtte brugerens lår 5 samt en nederste del 7 af brugerens baller. Sædeunderstøtningen 1 omfatter endvidere to bageste sædeflader 8, der er indrettet for at understøtte en øverste del 9 af brugerens baller. Når brugeren i sidder i stolen vil der være etableret et korrekt svaj i lænden 10 på grund af indbyrdes 30 vinkler mellem sædeflademe 6,8.25 The seat support is formed by four seat surfaces. Two front seat surfaces 6 are provided which are intended to support the user's thighs 5 as well as a lower part 7 of the user's balls. The seat support 1 further comprises two rear seat surfaces 8 which are arranged to support an upper part 9 of the user's bales. When the user is sitting in the chair, a correct sway will be established in the lumbar 10 due to mutual angles between the seat surfaces 6,8.

] DK 173053 B1 s Sædeflademe 6 og 8 er parvis placeret symmetrisk på hver side af et lodret midtplan, der indikeret ved 11 i fig. 1.
