Description

den antar sin normale fremad konvekse form. "Den sistnevnte under-stbttelsesplate som anbringes direkte under brukerens rygg, kan ganske visst tjene til å rette pasientens ryggsbyle ui ;år han ligger på ryggen i helt utstrakt stilling, men den er ikke egnet til innbygning i f.eks. en stol med vinkelinnstillbar ryggstbtte eller en seng med bæreflater som kan vinkelinnstilles innbyrdes. De utadbbyde partier som i visse lenestoler tjener som særlig stbtte for korsryggen, kan heller ikke overfores direkte til stoler eller senger med et mer eller mindre skrått innstillbart ryggparti, idet det har vist seg at en understbttelse som befin-ner seg i en konstant avstand fra dreieaksen mellom en bæreflate for understbttelse. av ryggen og en bæreflate for understbttelse av setet, selv om den gir riktig understbttelse av korsryggen i liggende stilling, ikke vil gi den mest hensiktsmessige understbttelse når bæreflaten på ryggen dreies opp i en vinkelstilling, idet den på grunn av ryggsbylens anatomi og setepartiets plasering foran dreiningsaksen vil komme til å virke på et sådant parti av ryggsbylen at den nærmest understøtter bekkenpartiet, hvilket Ikke tjener noe nyttig formål, men tvertimot virker sjenerende. it assumes its normal forward convex shape. "The latter under-supporting plate, which is placed directly under the user's back, can certainly serve to straighten the patient's spine when he is lying on his back in a fully extended position, but it is not suitable for installation in, for example, a chair with angle adjustment back support or a bed with supporting surfaces that can be adjusted at an angle to each other. The protruding parts that in certain armchairs serve as special support for the lower back cannot be transferred directly to chairs or beds with a more or less obliquely adjustable back part, as it has been shown that a support located at a constant distance from the axis of rotation between a supporting surface for supporting the back and a supporting surface for supporting the seat, even if it provides the correct support for the lower back in the lying position, will not provide the most appropriate support when the supporting surface on the back is turned up into an angular position, as due to the anatomy of the spine and the position of the seat in front of the turn the ksen will come to work on such a part of the spinal abscess that it almost supports the pelvic part, which does not serve any useful purpose, but on the contrary seems embarrassing.

Formålet med oppfinnelsen er derfor å skape en slik innstillbar seng eller stol av den omhandlede art at lendestbtten i enhver vinkelstilling som bæreflaten til understbttelse av brukerens rygg inntar, kan understbtte ryggsbylen riktig på det sted hvor det er allermest påkrevet, dvs. midtfor lendehvirvlene. The purpose of the invention is therefore to create such an adjustable bed or chair of the type in question that the lumbar support in any angular position that the support surface for supporting the user's back takes, can support the spinal cord correctly in the place where it is most required, i.e. in the middle of the lumbar vertebrae.

Dette er ifblge oppfinnelsen oppnådd ved at leddforbindelser mellom den svingbare bæreflate og sengens eller stolens stativ er forbundet slik med stbtteorganet at dette forflytter seg i oppovergående retning på lendestbtten når bæreflaten svinges oppover. Det har vist seg at det er mulig å konstruere en slik lendestbtte, så at den i alle vinkelstillinger av den opp-svingbare bæreflate for brukerens rygg gir en så riktig og behagelig understbttelse av lenden at stbtteorganet praktisk talt ikke kan merkes, uansett om brukeren av stolen eller sengen hviler direkte på ryggen eller mer eller mindre på siden. According to the invention, this is achieved by joint connections between the swiveling support surface and the bed or chair stand being connected in such a way to the support member that it moves in an upward direction on the lumbar support when the support surface is swung upwards. It has been shown that it is possible to construct such a lumbar support, so that in all angular positions of the up-swinging support surface for the user's back it provides such correct and comfortable support for the lower back that the support device is practically unnoticeable, regardless of whether the user of the chair or bed rests directly on the back or more or less on the side.

En foretrukken utfbrelse av sengen eller stolen ifblge oppfinnelsen utmerker seg ved en på hver side av den svingbare bæreflate stivt anbragt nedadrettet arm som bærer en svingearm, hvis svingepunkt er innstillbart langsetter armen, og hvilken svingearm ved sin annen ende er forbundet med en arm med variabel virksom lengde som ved sin ene ende er svingbar om et innstillbart punkt på sengens eller stolens stativ og som ved sin motsatte ende er forbundet med en forskyvbar sleide som bærer stbtteorganet. De innstillbare dreiepunkter bevirker at lendestbttens avstand fra dreieaksen mellom setebæreflate og ryggbæreflate kan innstilles individuelt etter brukerens behov, og når innstillingen en gang er foretatt, vil stbtteorganet understbtte lenden riktig i enhver vinkelstilling av stolryggen eller den tilsvarende bæreflate på sengen. Det har vist seg at stbtteorganet for å virke tilfreds-stillende skal forskyves i stigende grad for en gitt vinkeldreie-bevegelse, når ryggbæreflaten dreies opp fra vannrett stilling til en viss skråstilling, hvoretter forholdet mellom forskyvning og vinkeldreining igjen skal avta når ryggbæreflatens stilling blir ennå steilere. Dette kan oppnås ved passende innstilling av leddforbindelsens dreiepunkter. A preferred embodiment of the bed or chair according to the invention is characterized by a rigidly arranged downward arm on each side of the pivotable support surface which carries a pivoting arm, the pivoting point of which can be adjusted along the length of the arm, and which pivoting arm is connected at its other end to an arm of variable effective length which at one end can be pivoted about an adjustable point on the bed or chair frame and which is connected at its opposite end to a displaceable slide which carries the support member. The adjustable pivot points mean that the distance of the lumbar support from the axis of rotation between the seat support surface and the back support surface can be set individually according to the user's needs, and once the setting has been made, the support body will support the lower back correctly in any angular position of the chair back or the corresponding support surface on the bed. It has been shown that, in order to work satisfactorily, the support member must be displaced to an increasing degree for a given angular rotation movement, when the back support surface is turned up from a horizontal position to a certain inclined position, after which the ratio between displacement and angular rotation must decrease again when the position of the back support surface remains steeper. This can be achieved by suitable setting of the joint connection's pivot points.

Por at understbttelsen skal virke etter hensikten og være behagelig å ligge på uansett om brukeren er mer eller mindre svai-rygget, er det ifblge oppfinnelsen hensiktsmessig at stbtteorganet omfatter en på sleiden dreibart lagret aksel med eksenterskiver som hver ligger an mot en lamell. In order for the support to work as intended and be comfortable to lie on regardless of whether the user has a more or less slouched back, it is appropriate according to the invention that the support means comprises a shaft rotatably mounted on the slide with eccentric discs, each of which rests against a slat.

Oppfinnelsen skal forklares nærmere nedenfor ved hjelp avThe invention will be explained in more detail below by means of

et eksempel i forbindelse med tegningen, hvor:an example in connection with the drawing, where:

Sig. 1 viser en del av en seng med anordningen ifblge oppfinnelsen og sett fra siden og fig. 2 det samme sett ovenfra. Sig. 1 shows part of a bed with the device according to the invention and seen from the side and fig. 2 the same seen from above.

Den viste seng har et stativ 1 , hvorpå det er anbragt en bæreflate 2 for understbttelse av pasientens sete og en i forhold, til denne bæreflate svingbar bæreflate 3 for understbttelse av pasientens rygg og hode. I den viste utfbrelsesform svinges bæreflaten 3 manuelt oppad og understbttes på kjent måte med en bbyle 4, men det vil forstås at bæreflaten 3 likesåvel kan svinges oppad ved hjelp av hydrauliske eller elektriske drivmekanismer. Langsgående lameller 5 er fastgjort til en tverrgående stang 6 The bed shown has a stand 1, on which is placed a support surface 2 for supporting the patient's seat and a support surface 3 that can be pivoted in relation to this support surface for supporting the patient's back and head. In the embodiment shown, the bearing surface 3 is manually swung upwards and supported in a known manner with a bracket 4, but it will be understood that the bearing surface 3 can also be swung upwards by means of hydraulic or electric drive mechanisms. Longitudinal slats 5 are attached to a transverse bar 6

i bæreflaten 3 og strekker seg inn i mellomrom mellom tilsvarende lameller 7 i bæreflaten 2. For tydelighets skyld er bare vist de lameller 5 som understbttes av eksenterorganer 8 på en tverrgående aksel 9 som danner lendestbtte. I den viste utfbrelsesform er vist tre eksenterorganer 8, hvorav det midterste er lavere enn de to ytterste, slik at en madrass som anbringes på sengen får er svak krumning i tverretningen. Eventuelt kan det midterste eksenterorgan utelates helt. Akselen 9 er dreibar i lagre i en sleide 10 på hver side av rammen og kan spennes fast i innstilt stilling ved hjelp av en ikke vist stramraeskrue. Sleiden 10 er dreibart forbundet med en teleskoparm 11 som ved sin motsatte in the support surface 3 and extends into spaces between corresponding slats 7 in the support surface 2. For the sake of clarity, only the slats 5 which are supported by eccentric members 8 on a transverse shaft 9 which form lumbar support are shown. In the embodiment shown, three eccentric members 8 are shown, the middle one of which is lower than the two outermost ones, so that a mattress that is placed on the bed has a slight curvature in the transverse direction. Optionally, the middle eccentric member can be omitted entirely. The shaft 9 is rotatable in bearings in a slide 10 on each side of the frame and can be clamped in the set position by means of a tightening screw, not shown. The slide 10 is rotatably connected to a telescopic arm 11 as with its opposite

ende har et dreiepunkt 12 som er forskyvbart i loddrett retning på en fra delen 1 nedadrettet arm 13. I stedet for armen 11 kan eventuelt anvendes en boltleddforbindelse med en langsgåande slisse som glir over en bolt i dreiepunktet 12. Teleskoparmen 11 end has a pivot point 12 which is displaceable in a vertical direction on an arm 13 pointing downwards from part 1. Instead of the arm 11, a bolt joint connection with a longitudinal slot that slides over a bolt in the pivot point 12 can possibly be used. The telescopic arm 11

er i avstand fra sin bverste ende dreibart forbundet med en svingearm 14, hvis motsatte ende er dreibart forbundet med en ved hver side av bæreflaten 3 fastsveiset nedadrettet arm 15»Dreie- is at a distance from its uppermost end rotatably connected to a swing arm 14, the opposite end of which is rotatably connected to a downwardly directed arm 15 welded to each side of the bearing surface 3"

punktet mellom armene 14 og 15 er forskyvbart langs den sist-the point between the arms 14 and 15 is displaceable along the last

nevnte arm som f.eks. som vist kan være forsynt med en rekke hull for en dreietapp. said arm as e.g. as shown can be provided with a number of holes for a pivot pin.

Ved å endre beliggenheten av dreiepunktet 12 og av dreie-By changing the location of the pivot point 12 and of the

punktet mellom armen 14 og armen 15 kan avstanden mellom dreie-the point between arm 14 and arm 15, the distance between turning

aksen mellom bæreflatene 2 og 3 og akselen 9, som danner lendestbtte, varieres og tilpasses individuelt etter pasientens behov f og enn videre kan stbrrelsen av den forskyvning av lendestbtten som fremkalles ved en gitt vinkeldreining herved endres. the axis between the bearing surfaces 2 and 3 and the axis 9, which forms the lumbar support, is varied and adapted individually according to the patient's needs f and furthermore, the movement of the displacement of the lumbar support which is induced by a given angular rotation can thereby be changed.

Lamellene 5 som fritt kan tilpasse seg til enhver stilling hvori de understbttes av eksenterorganene 8, gir en slik under- The slats 5, which can freely adapt to any position in which they are supported by the eccentric members 8, provide such a

stbttelse for sengens madrass at denne i enhver stilling av rammen 3 danner en jevnt krummet understbttelsesflate for pasientens rygghvirvelparti, og en plate som er behagelig å support for the bed's mattress that in any position of the frame 3 forms an evenly curved support surface for the patient's spine, and a plate that is comfortable to

ligge på uansett om pasienten ligger på ryggen eller på siden.lie on regardless of whether the patient lies on his back or side.

Det vil forstås at anordningen ifblge oppfinnelsen ogsåIt will be understood that the device according to the invention also

kan finne anvendelse ved stoler hvis ryggstbtte skal kunne svinges fra en sittestilling bakover til en hvilestilling slik som det f.eks. er tilfelle med stoler i fly og langturbusser. can be used in chairs whose backrest must be able to be swung from a sitting position backwards to a resting position such as e.g. is the case with seats in airplanes and long-distance buses.
