Den foreliggende opfindelse angår en stol såsom en lænestol med omstillingsmulighed mellem to stillinger, såsom en siddestilling, der er optimalt egnet til konversation, læsning, tv-kikning o.lign. og en mere udpræget hvilestil1ing. Med siddestilling forstås her en stilling med 5 forholdsvis opret rygstøtte, og hvor brugeren af stolen har fødderne på gulvet, mens der ved hvilesti11 ingen forstås en stilling, hvor fødderne er hævet, idet en form for fodskammel støtter underbenene.The present invention relates to a chair such as an armchair with the possibility of switching between two positions, such as a sitting position which is optimally suitable for conversation, reading, television viewing and the like. and a more distinct resting position. By sitting position here is meant a position with 5 relatively upright backrests, and where the user of the chair has his feet on the floor, while no resting position is understood to mean a position where his feet are raised, a form of footstool supporting the lower legs.

Der har i tidens løb været udtænkt utallige former for stole med omstillingsmulighed med henblik på at tilgodese specielle ønsker til 10 formen af stolen eller ønsker om valgmulighed, således at stolen kan anvendes til varierende formål eller eventuelt blot med det formål, at brugeren fra tid til anden kan skifte siddestilling. En hvilestilling med løftede fødder kan eksempelvis være meget behagelig, men er på den anden side ikke altid hensigtsmæssig, f.eks. hvis man ønsker at kunne 15 rejse sig op hurtigt. En stol med fast forlængelse til støtte for underben får desuden så stor længde, at alene pladshensynet er vigtigt nok til, at mange ønsker mulighed for på en eller anden måde at kunne fjerne fodstøtteelementet, når det ikke er i brug. Der kendes f.eks. stole med hængslede klapper, der kan svinges op til fodstøtte og svinges nedad, 20 når de ikke er i brug. De nedfældede klapper giver imidlertid stolen et mindre tiltalende og ret tungt udseende, og de vil være i vejen eksempelvis ved rengøring under stolen. Desuden må de nødvendigvis have en eller anden form for fikseringsmekanisme, som komplicerer betjeningen.Numerous types of chairs have been devised over the course of time with the possibility of adapting special wishes to the shape of the chair or wishes of choice, so that the chair can be used for varying purposes or possibly simply for the purpose of the user from time to time. another can change sitting position. For example, a resting position with raised feet can be very comfortable, but on the other hand is not always appropriate, e.g. if you want to be able to get up quickly. In addition, a chair with a fixed extension to support the lower leg is of such length that the space considerations alone are important enough that many want to be able to somehow remove the footrest element when not in use. It is known e.g. chairs with hinged flaps that can be swung up to the footrest and swung downwards 20 when not in use. However, the folded flaps give the chair a less appealing and rather heavy appearance, and they will be in the way, for example, when cleaning under the chair. Furthermore, they must necessarily have some sort of fixation mechanism that complicates the operation.

Indstillingsmekanismen eller betjeningsmekanismen kan udformes på 25 mange måder, og det skal her blot anføres, at det forekommer umiddelbart tiltalende og let forståeligt, hvis den er indrettet, så brugeren kan stille det pågældende element ved simpelthen at gribe om det med en hånd og føre det til den ønskede position. Dette kræver imidlertid et ekstra betjeningsgreb til en fikseringsmekanisme, eller elementet må føres i-30 gennem et særligt og for brugeren ikke umiddelbart indlysende bevægelsesprogram, som udløser en automatisk fikseringsmekanisme. Begge disse betjeningsmåder opleves som besværlige - og det i en grad, så mange brugere opgiver at anvende dem.The setting mechanism or the operating mechanism can be designed in many ways, and it should be stated here that it appears immediately appealing and easily understandable if it is arranged so that the user can position that element by simply grasping it with one hand and leading it to the desired position. However, this requires an additional control handle for a fixing mechanism, or the element must be guided through a special and not immediately obvious movement program which triggers an automatic fixing mechanism. Both of these modes of operation are perceived as cumbersome - and to a degree that many users give up using them.

Et vigtigt aspekt ved alle stole er faconen af rygstøttefladen, og 35 det er velkendt, at der er forskellige ønsker til den afhængigt af stolens anvendelse. Ønsker brugeren at indtage en forholdsvis opret stilling, f.eks. under konversation, ønskes en forholdsvis opret understøtning for ryggen, mens hovedet skal være frit, så det kan drejes ugene-An important aspect of all chairs is the shape of the backrest surface, and it is well known that there are different desires for it depending on the use of the chair. Does the user wish to take a relatively upright position, e.g. during conversation, a relatively upright support for the back is desired, while the head must be free so that it can be turned weekly.

2 ret. Til en hvilestilling er det derimod ofte hensigtsmæssigt med understøtning til hovedet eventuelt i form af en fremskudt nakkestøtte.2 ret. For a resting position, on the other hand, support for the head is possibly appropriate in the form of an extended head restraint.

Til hvile ønskes endvidere en mere bagud lænet rygunderstøtning i forhold til det, som foretrækkes til mere aktive sysler, og for at til -5 godese dette kendes der også utallige udformninger af stole, hvor ryglænet kan vippes. Ved fast indstilling af sædet og vipning af ryglænet forskydes kroppen imidlertid i forhold til både siddestøtteflade og rygstøtteflade, og hvis disse flader skal være facontilpassede, kan ryglænet derfor ikke vippes særlig meget, før brugerens placering bliver for-10 kert i forhold til facontilpasningen. Desuden kræver omstilling af ryglænshældningen nødvendigvis indstillelige fikseringsmekanismer, som medfører de ovennævnte ulemper.In addition, for a more backward leaning back support compared to that preferred for more active pursuits, a more desirable shape is also known for countless designs of chairs where the backrest can be tilted. However, when firmly adjusting the seat and tilting the backrest, the body is displaced relative to both the seat support surface and the back support surface, and if these surfaces are to be shape-adjusted, the backrest cannot therefore be tilted very much until the user's position is improper with respect to the shape adjustment. In addition, adjusting the backrest inclination necessarily requires adjustable fixing mechanisms which cause the aforementioned disadvantages.

God facontilpasning ud over et bredere område af hældninger kan naturligvis opnås, hvis sædestøttef1aden og rygstøttefladen vippes tilsam-15 men, dvs. så vinklen imellem dem holdes konstant eller stort set konstant. De hidtil kendte stole opbygget efter dette princip udviser imidlertid væsentlige praktiske ulemper.Good shape adjustment over a wider range of slopes can, of course, be achieved if the seat support surface and the back support surface are tilted together, ie. so the angle between them is kept constant or largely constant. However, the prior art chairs constructed according to this principle exhibit significant practical disadvantages.

En teknisk simpel løsning hertil er placeringen af en svingeaksel under sædet, dvs. i en afstand under tyngdepunktet for sæde og ryglæn.A technically simple solution for this is the placement of a pivot shaft under the seat, ie. at a distance below the center of gravity of the seat and backrest.

20 Herved bliver indstillingsbevægelsen imidlertid let ustabil, når man kommer ud i yderstillingerne, i en grad, som kan overraske brugeren.20 However, the setting movement becomes slightly unstable when entering the outer positions, to a degree that may surprise the user.

Dette kan undgås med stole, hvor man med buede skinneføringer eller lignende midler placerer omdrejningspunktet i eller oven over tyngdepunktet af sæde og ryglæn. I begge disse tilfælde kommer sædeforkantens højde o-25 ver gulv imidlertid til at variere, så den er lavest i oprejst stilling og højest i hvilestilling, hvilket er absolut uønsket ud fra et komfortmæssigt hensyn.This can be avoided with chairs where, with curved rail guides or similar means, the pivot point is placed in or above the center of gravity of the seat and backrest. In both of these cases, however, the height of the seat front o-25 across the floor will vary, so that it is lowest in the upright position and highest in the resting position, which is absolutely undesirable from a comfort standpoint.

Hvis gulvafstanden skal være optimal i alle stillinger for en stol, hvor sæde og ryglæn vippes sammen om en vandret tværgående akse, bør 30 denne akse placeres tæt ved sædeforkanten, så den er tæt ved brugerens knæled. Herved kommer aksen nødvendigvis til at ligge langt uden for den svingbare dels tyngdepunkt, så brugeren skal løfte og sænke en så tung masse, at der i praksis må indrettes fjedermekanismer, spindeldrev, omfangsrige vægtstangsmekanismer eller andre komplicerede konstruktioner.If the floor spacing is to be optimal in all positions of a chair where the seat and backrest are tilted about a horizontal transverse axis, this axis should be positioned close to the seat leading edge so that it is close to the user's knee joint. In this way, the axis will necessarily be far outside the center of gravity of the pivot, so that the user must lift and lower such a heavy mass that in practice spring mechanisms, spindle drives, bulky lever mechanisms or other complicated structures must be fitted.

35 Ifølge opfindelsen tilvejebringes en stol omfattende et understel, et sædeelement og et rygelement, hvor sædeelementet omfatter en sædehynde med en sædestøtteflade, hvor rygelementet omfatter en ryghynde med en rygstøtteflade, og hvor rygelementet er fast eller svingbart i forhold 3According to the invention there is provided a chair comprising a chassis, a seat element and a smoking element, the seat element comprising a seat cushion with a seat support surface, the smoking element comprising a back cushion with a back support surface and the smoking element being fixed or pivotal in relation to 3.

til sædeelementet, hvilken stol er ejendommelig ved, at der er indrettet et yderligere element med en hynde, hvilket element er svingbart om en stort set vandret og tværgående akse arrangeret i afstand under sædeelementet og kan hvile i mindst to stillinger, nemlig en oprejst stilling, 5 hvor svingeelementets hynde ligger ind mod og op ad rygelementet, og en nedfældet stilling, hvor svingeelementets hynde danner en fremadrettet forlængelse af sædeelementet.to the seat element, the chair being characterized by the fact that an additional element with a cushion is arranged, which element is pivotable about a substantially horizontal and transverse axis arranged at a distance below the seat element and can rest in at least two positions, namely an upright position, 5, wherein the pivot member cushion lies against and up the smoking member, and a folded-down position wherein the pivot member cushion forms a forward extension of the seat member.

Der opnås herved en stol, hvor fodskammel elementet kan svinges frem eller væk efter behov på uhyre enkel måde, og hvor fodskammel elementet 10 ikke er i vejen eller virker generende for udseendet, når det ikke er i brug. Når vippeelementet eller vippeklappen, der anvendes som fodskammel, svinges tilbage mod ryglænet, anvendes den side, der da vender fremad, som rygstøtte. Det bliver derfor muligt at udforme stolens rygelement, så det er optimalt for hvilestillingen, dvs. med lidt vigende 15 rygstøtteflade og fremad ragende nakkestøttefremspring, og samtidig kan vippeelementets rygstøtteside udformes, så der opnås den mest hensigtsmæssige støtte i den oprejste siddestilling, i princippet uden at være bundet af den facon, som stolen frembyder i hvil esti 11 ingen.There is thus obtained a chair in which the footstool element can be swung forward or away as required in an extremely simple manner, and where the footstool element 10 is not in the way or acts as a nuisance when not in use. When the rocker or rocker flap used as a footstool is pivoted back against the backrest, the side then facing forward is used as a backrest. Therefore, it becomes possible to design the chair's smoking element so that it is optimal for the rest position, ie. with a slightly reclining 15 backrest surface and forward projecting headrest protuberance, and at the same time the backrest side of the rocker element can be designed to provide the most appropriate support in the upright sitting position, in principle without being bound by the shape presented by the chair in rest.

Ifølge en hensigtsmæssig videreudvikling af opfindelsen tilveje-20 bringes en stol, der er ejendommelig ved, at sædeelementet er indrettet svingbart i forhold til understellet omkring en stort set vandret, tværgående akse arrangeret under sædestøttef1aden og lidt inden for dens forreste kant imellem en siddestilling og en hvilestilling.According to a suitable further development of the invention there is provided a chair which is characterized in that the seat element is pivotally arranged relative to the chassis about a substantially horizontal, transverse axis arranged under the seat support surface and slightly within its front edge between a seating position and a seat position. resting position.

Der opnås herved en stol, hvor sæde og ryglæn kan hældes noget bag-25 over til hvilestilling, hhv. rejses lidt mere op til siddestilling, ved svingning omkring en vandret tværgående akse, som ligger tæt ved sædeforkanten, således at forkantens højde over gulv er optimal for begge stillinger af stolen.A chair is thereby obtained in which the seat and backrest can be tilted slightly backwards to a resting position, respectively. is raised slightly more to the sitting position, by pivoting around a horizontal transverse axis, which is close to the seat front, so that the height of the front edge above the floor is optimal for both positions of the chair.

Ifølge en hensigtsmæssig udførelsesform tilvejebringes en stol, der 30 er ejendommelig ved, at svingeelementet omfatter et støtteorgan for sædeelementet bestående af en aksel parallel med svingeelementets akse og arrangeret i afstand derfra, hvor dette støtteorgan støtter imod gi ideskinner på sædeelementet og kan forskydes langs gi ideskinnerne under svingning af svingeelementet mellem dets forskellige positioner.According to a suitable embodiment, a chair is provided in that the pivot member comprises a support member for the seat member consisting of a shaft parallel to the axis of the pivot member and spaced therefrom, whereby this support member supports against idle rails on the seat member and can be displaced along the idle rails. during pivoting of the pivot member between its various positions.

35 Herved opnås, at hele svingeelementet kan udnyttes som vægtstang, så sæde- og rygdelen kan svinges op og ned med meget beskeden kraftudfoldelse.35 It is thus achieved that the entire swing element can be utilized as a lever, so that the seat and back part can be swung up and down with very modest force exertion.

Ifølge en hensigtsmæssig udførelsesform fungerer mekanismen såle-According to a suitable embodiment, the mechanism functions as such.

DK 163953 BDK 163953 B

4 des, at sæde- og rygdelen, når den rejses op ved bevægelse af svingeelementet, føres op over et dødpunkt, så den under den sidste del af svin-geelementets bevægelse sænkes en lille smule ned igen. Herved opnås en selvlåsende, stabiliserende virkning, idet vægten af stolesæde og ryglæn 5 virker til at fastholde vippeelementet.4, that when the seat and back section is raised by movement of the pivot element, it is raised above a dead point, so that it is lowered slightly again during the last part of the pivot element movement. Hereby, a self-locking, stabilizing effect is obtained, the weight of the chair seat and backrest 5 acting to hold the rocker element.

Stolen kan være udformet således, at sædehældningen i siddestillingen er omkring 10°, mens den i hvilestillingen er omkring 25°, dvs. der sker en omstilling svarende til 15°s svingning. Oversiden af svingeele-mentets hynde i nedfældet stilling, dvs. fladen til at støtte underbene-10 ne, er omtrent vandret.The chair may be designed such that the seat inclination in the sitting position is about 10 °, while in the resting position it is about 25 °, ie. there is a change corresponding to 15 ° oscillation. The upper surface of the pivot member cushion in the folded position, ie. the surface to support the lower legs is approximately horizontal.

Ifølge en anden hensigtsmæssig udførelsesform er et yderligere støtteorgan drejeligt forbundet til svingeelementet, så det skydes lidt frem fra stolesædets forkant, når svingeelementet svinges ned, således at svingeelementet afstøttes mod dette støtteorgan. Herved opnås en sta-15 bil og sikker placering af fodskammelelementet.According to another convenient embodiment, a further support member is pivotally connected to the pivot member so that it is slightly projected from the front of the chair seat as the pivot member is pivoted down so that the pivot member is supported against this support member. This provides a sta-15 car and secure placement of the footstool element.

Ifølge endnu en hensigtsmæssig udførelsesform er stolens understel udformet af fjederstål, hvorved det opnås, at stolen kan gynge ganske let.According to yet another convenient embodiment, the chair's base is made of spring steel, which means that the chair can swing quite easily.

Alle figurer er forenklede principskitser af de centrale elementer, idet alle detaljer, som ikke er nødvendige for forståelsen af opfindel-10 sen, er udeladt.All figures are simplified principle sketches of the central elements, omitting all details not necessary for the understanding of the invention.

Fig. 1 og 2 viser sidebilleder af en stol 1 ifølge den første udførelsesform af opfindelsen, hvor hovedkomponenterne er et understel 2, en sædehynde 6, en ryghynde 7, en nakkepølle 8 og et svingeelement 11. Understellet 2 omfatter fodstykket 3 beregnet til afstøtning mod en vand-15 ret understøtningsflade, og fra fodstykket 3 udgår der skråt opad og fremad en opstander 4, hvortil der halvt oppe er fastgjort et hængsel 10, og øverst oppe er opstanderen fast forbundet med sædehynden i et område nær dens forkant. Sædehynden 6 er fast forbundet med ryghynden 7, som igen er fast forbundet med nakkepøllen 8.FIG. 1 and 2 show side views of a chair 1 according to the first embodiment of the invention, wherein the main components are a chassis 2, a seat cushion 6, a back cushion 7, a neck puddle 8 and a swing element 11. The chassis 2 comprises the footpiece 3 intended for impact against a water -15 straight support surface, and from the footpiece 3, an upright 4 proceeds upwardly and an upright 4 to which a hinge 10 is mounted halfway up, and at the top up, the upright is firmly connected to the seat cushion in an area near its leading edge. The seat cushion 6 is firmly connected to the back cushion 7, which in turn is firmly connected to the neck paw 8.

20 Hængslet 10 er arrangeret med aksen vandret og på tværs af stolen omtrent midt under stolesædet og i nogen afstand derunder. Hængslet 10 er drejepunktet for et svingeelement 11, der omfatter stivere, som udgår fra hængslet 10 og ud omkring begge sider af sædehynden og op til svin-gehynden 14, som i fig. 1 ligger an mod ryghynden 7. En person, som sæt-25 ter sig i stolen i den stilling, der er vist i fig. 1, vil således sidde på sædehynden 6 og vil kunne støtte ryggen mod svingehyndens 14 rygstøtteside 15, og personen vil kunne støtte hovedet eller nakken mod nakkepøllen 8.20 The hinge 10 is arranged with the axis horizontal and across the chair approximately in the middle of the chair seat and at some distance below it. The hinge 10 is the pivot point of a pivot member 11 comprising struts extending from the hinge 10 and out around both sides of the seat cushion and up to the pivot cushion 14, as in FIG. 1 abuts the dorsal cushion 7. A person who sits in the chair in the position shown in FIG. 1, will thus sit on the seat cushion 6 and will be able to support the back against the back support side 15 of the swing pad 14, and the person will be able to support the head or neck against the neck paw 8.

I det tilfælde brugeren ønsker støtte til at sidde med fødderne hæ-30 vet, svinger han da helt enkelt svingeelementet 11 ned fra stillingen vist i fig. 1 og til stillingen vist i fig. 2, hvor dele af svingeelementet 11 kommer til anlæg mod det øverste stykke af opstanderen 4, og det forstås, at svingeelementet er udformet således, at svingehynden i denne position indtager en omtrent vandret stilling med lægstøttesiden 35 16 opad. Ryghynden 7 er udformet, så den giver behagelig understøtning af ryggen, og idet svingehynden har en vis tykkelse, forstås det ved sammenligning af fig. 1 og 2, at brugeren i hvilestillingen vil opleve nakkepøllen 8 mere fremtrædende, dvs. at der er fast understøtning tilIn case the user wants support to sit with his feet raised, he simply swings the pivot element 11 down from the position shown in FIG. 1 and to the position shown in FIG. 2, where portions of the pivot member 11 come into contact with the uppermost portion of the upright 4, and it is understood that the pivot member is designed such that the pivot cushion in this position assumes an approximately horizontal position with the leg support side 35 16 facing up. The dorsal cushion 7 is designed to provide comfortable back support, and since the cushion cushion has a certain thickness, it is understood by comparing FIG. 1 and 2, that the user in the resting position will experience the neck paw 8 more prominent, ie. that there is firm support for

6 hovedet i stillingen i fig. 2.6 shows the head in the position of FIG. 2nd

Ved den anden udføre!sesform af opfindelsen, vist i sidebilleder i fig. 3 og 4, er sædehynden 6 fastgjort til opstanderen 4 i et område under sædets forkant ved et hængsel 5, så sæde- og ryglænsdelen er sving-5 bar omkring hængslet 5 i forhold til understellets opstander 4. Der er derfor tilvejebragt en understøtning for sædehynden i et punkt bag ved hængslet. Denne understøtning er etableret derved, at sædehynden 6 er forsynet med gi ideskinner 9 på undersiden, mens svingeelementet omfatter en travers 12, som kan bære imod gi ideskinnerne 9. Ved svingning af 10 svingeelementet fra positionen vist i fig. 3 og ned til stillingen vist i fig. 4 opnås derfor dels fodstøtte og rygunderstøtningsflade svarende til fig. 2, men ydermere en vipning af sædehynde og ryghynde tilsammen ned til positionen vist i fig. 4, som er hvil esti 11 ingen.In the second embodiment of the invention, shown in side views in FIG. 3 and 4, the seat cushion 6 is attached to the upright 4 in a region below the front edge of the seat at a hinge 5, so that the seat and backrest portion is pivotal 5 about the hinge 5 relative to the upright of the chassis 4. A support for the seat cushion is therefore provided. at a point behind the hinge. This support is established in that the seat cushion 6 is provided with gi idea rails 9 on the underside, while the pivot element comprises a traverse 12 which can bear against the gi idea rails 9. When pivoting the pivot element from the position shown in fig. 3 and down to the position shown in FIG. 4, foot support and back support surface corresponding to FIG. 2, but furthermore a tilt of seat cushion and back cushion together down to the position shown in fig. 4, which is where no 11.

I det følgende forklares en praktisk udførelsesform af stolen iføl-15 ge en tredie udførelsesform af opfindelsen mere detaljeret under henvisning til fig. 5-10.In the following, a practical embodiment of the chair according to a third embodiment of the invention is explained in more detail with reference to FIG. 5-10.

For at de enkelte elementer skal kunne ses tydeligt, er polstringen udeladt fra disse figurer, og det anses at ligge inden for en fagmands kunnen at udforme og påsætte en passende polstring uden nærmere forkla-20 ring hertil.In order that the individual elements can be clearly seen, the padding is omitted from these figures, and it is considered to be within the skill of a person skilled in the art to design and apply a suitable padding without further explanation.

Fig. 5, 6 og 7 viser alene et understel principielt svarende til det ovenfor nævnte understel 2 og en stativdel til sæde og ryglæn med nakkepølle, dvs. en stativdel, som anvendes til understøtning af elementer svarende til sædehynden 6, ryghynden 7 og nakkepøllen 8.FIG. 5, 6 and 7 only show a frame in principle similar to the above mentioned frame 2 and a stand part for seat and backrest with neck padding, ie. a tripod member used to support elements corresponding to the seat cushion 6, the back cushion 7 and the neck pouch 8.

25 Understellet 22 i denne udførelsesform omfatter et fodstykke 23, som set i planbillede (fig. 7) er omtrent af form som et H, og som eventuelt kan være svagt forkrøbbet ved enderne, som det ses i fig. 5 og 6, eller det kan være forsynet med fødder ved enderne, så det kan stå på et vandret underlag. Fodstykket kan være udført i kraftigt fjederstål. Til 30 forbindelsesgrenen i H'et er der påsvejset en opstander 24 ligeledes af fjederstål og forløbende skråt opad og fremad. Opstanderen er i planbillede (fig. 7) omtrent U-formet, og øverst på opstanderen fastholdes et tværgående stykke rundstål 28 med små spændebøjler 29, så rundstålet kan dreje til etablering af et hængsel.The chassis 22 in this embodiment comprises a footpiece 23 which, as seen in plan view (Fig. 7), is approximately of the shape of an H and which may be slightly crippled at the ends as seen in Figs. 5 and 6, or it may be provided with feet at the ends so that it can stand on a horizontal surface. The foot piece may be made of strong spring steel. To the connecting branch in the H, an upright 24 is also welded of spring steel and extending obliquely upwards and forwards. The upright is in plan view (Fig. 7) approximately U-shaped, and at the top of the upright a transverse piece of circular steel 28 with small clips 29 is retained so that the circular steel can rotate to establish a hinge.

35 Sæderammen er opbygget med fire længdestivere 30, som er indbyrdes parallelle og fastsvejset til rundstålet 28 fortil. På undersiden af to af længdestiverne 30 er der fastgjort gi ideskinner 35 til understøtning af sæderammen. Ved forenderne af længdestiverne er der påsvejset en for- 7The seat frame is constructed with four longitudinal struts 30 which are parallel to one another and welded to the round steel 28 at the front. On the underside of two of the longitudinal struts 30 are secured idle rails 35 to support the seat frame. At the ends of the longitudinal struts, a front 7 is welded

At the rear of the longitudinal struts 30, a transverse beam 27 is welded which at the laterally projecting ends connects to lateral struts 32 which extend rearwardly 5 and to the rearwardly interconnect through the transverse beam 33. On the transverse beam 27 a rearwardly extending tube 31 is welded in approximately U-shaped and extending in the same plane as the longitudinal struts 30. A pipe piece 34 is bent in shape to define the backrest, and it is welded down to the U-pipe 31 and above to the cross beam 33, so that a stable construction is obtained. The backrest holder tube 34 forms extremely rounded corners to which the furniture upholstery may conveniently be attached.

I det følgende henvises der til fig. 8, 9 og 10, hvor der er vist visse yderligere komponenter til stolen ifølge den tredie udførelsesform. Mere konkret vises igen understellet 22 samt en stativdel til et 15 element svarende til det i forbindelse med fig. 1 nævnte svingeelement 11.Referring now to FIG. 8, 9 and 10, certain additional components of the chair according to the third embodiment are shown. More specifically, the chassis 22 and a stand part for a member 15 similar to the one shown in FIG. 1, said swivel element 11.

Fig. 8, 9 og 10 viser det samme understel 22 som omtalt i forbindelse med fig. 5, 6 og 7, og det skal hertil blot tilføjes, at der er vist et hængsel for svingeelementet 41 opbygget af et rundstål 44, der 20 kan dreje i U-formede spændebøjler 29 fastskruet på understellets opstander 24 i et område nær dennes midte. Idet der henvises til fig. 10, ses, at svingeelementet 41 omfatter to korte bærearme 45 udgående fra rundstålet 44, og til hvis forreste ender der er påsvejset en travers 42, som rager ud til siderne. Enderne af traversen 42 går over i side-25 grene 43, der forløber ud mod venstre i fig. 10 ind til endeområder, hvor de er bukket skråt tilbage til dannelse af trapezformet forløbende sideholdere 46. Imellem sideholderne 46 er der til venstre i figuren påsvejset en forholdsvis lang tværbjælke 47 og til højre i figuren påsvejset en forholdsvis kortere tværbjælke 48. Svingeelementets hynde afstøt-30 tes af sideholderne 46 og tværbjælkerne 47 og 48.FIG. 8, 9 and 10 show the same chassis 22 as discussed in connection with FIGS. 5, 6 and 7, it should be added only that there is shown a hinge for the pivot member 41 constructed of a round steel 44 which 20 can rotate in U-shaped clamps 29 screwed on the uprights 24 of the chassis 24 in an area near the center thereof. Referring to FIG. 10, it is seen that the pivot member 41 comprises two short support arms 45 starting from the round steel 44, and to the front ends of which is mounted a traverse 42 projecting to the sides. The ends of the traverse 42 extend into side-25 branches 43 extending to the left of FIG. 10 into end regions where they are bent obliquely to form trapezoidal extending side holders 46. Between the side holders 46 a relatively long cross beam 47 is welded to the left of the figure and to the right of the figure a relatively shorter cross beam 48 is welded. 30 of the side holders 46 and the crossbeams 47 and 48.

Traversen 42 danner understøtning for sæderammen, idet gi ideskinnerne 35 kan glide på den, hvorved sæderammen vippes, når svingeelementet svinges, som ovenfor forklaret under henvisning til fig. 3 og 4.The traverse 42 provides support for the seat frame, in that the idle rails 35 can slide on it, thereby tilting the seat frame as the pivot member is pivoted, as explained above with reference to FIG. 3 and 4.

Som det særligt tydeligt ses i fig. 8, forløber svingeelementets 35 sidegrene 43 med en vis vinkel i forhold til retningen af bærearmene 45, og sideholderne 46 er igen drejet en vis vinkel i forhold til sidegrenene 43. Tværbjælkerne 47 og 48 er svagt indadbuede, dvs. til højre vist i fig. 7, så de svarer til faconen af ryghyndepolstringen (ikke vist). Af-As is particularly evident in FIG. 8, the lateral branches 43 of the pivot element 35 extend at a certain angle with respect to the direction of the support arms 45, and the side holders 46 are again turned a certain angle with respect to the side branches 43. The transverse beams 47 and 48 are slightly inwardly curved, ie. to the right shown in FIG. 7 so that they correspond to the shape of the dorsal cushioning (not shown). Of-

8 standen mellem svingeelementets sidegrene 43 er så stor, at de under svingebevægelsen frit kan passere uden for sædets sider.8 the position between the side branches 43 of the swing element is so large that during the swing movement they can freely pass outside the sides of the seat.

Idet der henvises til fig. 10, ses en omtrent rektangulær støtteramme 51, der i den ene ende er fastgjort ved en drejelig holder 52 til 5 traversen 42 på svingeelementet. Støtterammen 51 hviler oven på rundstå let 28, og på den færdigsamlede stol begrænses bevægelse af støtterammen 51 i opadgående retning af sædeforbjælken 26. Der er så meget spillerum mellem rundstålet 28 og forbjælken 26 (fig. 6 og 7), at støtterammen 51 uhindret kan forskydes frem og tilbage, når den følger bevægelsen af 10 svingeelementets travers 42. Når svingeelementet er i oprejst stilling som vist i fig. 8, er støtterammen 51 trukket længst tilbage, og den kan her være skjult under sædehynden. Når svingeelementet 41 fældes ned til stillingen vist i fig. 9, vil støtterammen 51 blive bevæget fremad, og den kan herved danne støtte for svingehynden i området nær ved tværbjæl-15 ken 48, så der opnås en stabil afstøtning og god fastlæggelse af svinge- hyndens position i nedfældet stilling.Referring to FIG. 10, a roughly rectangular support frame 51, secured at one end by a swivel holder 52 to 5, the traverse 42 on the pivot member. The support frame 51 rests lightly on top of the round bar 28, and on the finished assembly, movement of the support frame 51 in the upward direction is restricted by the seat bar 26. There is so much clearance between the round steel 28 and the front bar 26 (Figures 6 and 7) that the support frame 51 can be unobstructed. is shifted back and forth as it follows the movement of the pivot member traverse 42. When the pivot member is in the upright position as shown in FIG. 8, the support frame 51 is retracted to the farthest, and it may here be hidden under the seat cushion. When the pivot member 41 is lowered to the position shown in FIG. 9, the support frame 51 will be moved forward, and it can thereby provide support for the pivot cushion in the area near the transverse beam 48, so that a stable support and good determination of the position of the pivot cushion in the folded position are obtained.

Omend stolen er beskrevet i en konkret udførelsesform, er det klart, at der kan foretages modifikationer heraf, uden at det går ud o-ver opfindelsens rammer. Eksempelvis kunne ryglænet indrettes vipbart i 20 forhold til sædet ved at indrette et hængsel element bagtil på U-røret 31 til ryglænsstiverne og en længdeindstillingsmulighed i forbindelse med sidestiverne 32.Although the chair is described in a specific embodiment, it will be appreciated that modifications thereof may be made without departing from the scope of the invention. For example, the backrest could be tilted in relation to the seat by arranging a hinge element at the rear of the U-tube 31 for the backrest struts and a length adjustment option in connection with the side struts 32.
