Description
i DK 166798 B1in DK 166798 B1
Opfindelsen angår en sædebærer til drejelige arbejdsstole, i det væsentlige bestående af et grundlegeme med en for enden fastgjort støtte for den kraftsluttende forbindelse med et centralt støtteben for sædebæ-5 reren, en sædepladeholder og en ryglænbærer samt indstillingsmidler til udløsning af forud givne funktioner hos sædebæreren og dens dele, hvor ryglænbæreren er u-formet og med sit nederste endeområde er ført til ca. midt under sædepladen og har en tværbolt, der forbinder 10 den ligeledes U-formede sædepladeholder ved dennes bageste ende med ryglænbæreren på hængsellignende måde, mens den forreste ende af sædepladeholderen ved hjælp af en yderligere tværbolt er forbundet på hængsellignende måde med det U-formede grundlegeme, der forløber 15 nedefter under dannelse af en spids vinkel med sædepladeholderen og bærer en tværbolt, som er bevægelig i en kulisseføring af i det mindste et forbindelsesled, der er tilsluttet ved ryglænbæreren, og hvor der er tilvejebragt et koaksialt med den nedre tværbolt af grundle-2Q gemet indrettet tilspændingsorgan til kraftsluttende forbindelse af forbindelsesleddet med grundlegemet.BACKGROUND OF THE INVENTION The invention relates to a seat support for swivel work chairs, consisting essentially of a basic body with an end-fixed support for the force-fastening connection with a central support leg for the seat support, a seat plate holder and a backrest carrier and adjusting means for performing predetermined functions of the seat support. and its parts where the backrest carrier is un-shaped and with its lower end region is led to approx. in the middle below the seat plate and has a cross bolt connecting the likewise U-shaped seat plate holder at its rear end to the backrest carrier in a hinge-like manner, while the front end of the seat plate holder is connected in a hinge-like manner to the U-shaped base body. extending 15 downwardly to form a pointed angle with the seat plate holder and carrying a transverse bolt movable in a backstop of at least one connecting joint connected to the backrest carrier and having a coaxial with the lower transverse bolt of the base -2Q stored tightening means for force-closing connection of the connector with the base body.
En sædebærer af denne art kendes fra DE-brugsmodel nr. 8326792.A seat carrier of this kind is known from DE utility model no. 8326792.
Det er kendt at udruste sædemøbler af nyere dato med 25 en række metalliske dele, hvoraf i det væsentlige kan nævnes sædebæreren, en søjle, som støtter denne mod et fodstykke, og selve fodstykket. Sædebæreren, der alt efter sædemøblets udførelse kan have en mere eller mindre kompliceret mekanik til diverse funktioner, er ofte 30 udført T-formet og udgøres af nogle funktionsdele, hvoraf de væsentlige er et såkaldt grundlegeme og en ryglænholder. Med henblik på at kunne indstille ryglænets hældning i forhold til sædefladen er ryglænholderen tilsluttet grundlegemet på hængsellignende måde, og grund-35 legemet selv er over forbindelsesmidler forbundet med DK 166798 B1 2 sædefladen. Støtten, der fortrinsvis er forbundet kraftsluttende med grundlegernet, har ved sin mod grundlegemet vendende ende en konus, som indgriber kraftsluttende i en konusformet bøsning og derved sikrer en fast for-5 bindelse mellem støtte og sædebærer. Med henblik på at udløse funktionen af støtten, der ofte kan være en gasfjeder, er der gennem sædebæreren ført betjeningsmidler, hvoraf ét betjeningsorgan er udløsningsarmen for gasfjederens udløsningsmekanik. Med henblik på at etablere 10 ryglænholderens hældning i forhold til sædebæreren er denne både tilsluttet grundlegemet på hængsellignende måde og forsynet med arreteringsmidler, som fastholder den øjeblikkelige hældningsindstilling for ryglænet og/eller sædefladen.It is known to furnish seat furniture of recent date with a variety of metallic parts, of which there can be essentially mentioned the seat-carrier, a column supporting it against a footpiece, and the footpiece itself. The seat carrier, which, depending on the design of the seat furniture, may have a more or less complicated mechanism for various functions, is often made of T-shaped and is made up of some functional parts, the essentials of which are a so-called basic body and a backrest holder. In order to be able to adjust the inclination of the backrest relative to the seat surface, the backrest holder is connected to the base body in a hinge-like manner, and the base body itself is connected to the seat surface by means of connection with DK 166798 B1 2. The support, which is preferably connected forcefully to the base member, has at its end facing the base body a cone which engages forcefully in a cone-shaped sleeve and thereby ensures a firm connection between the support and seat support. In order to trigger the function of the support, which can often be a gas spring, actuators have been passed through the seat carrier, one of the controls being the release lever for the gas spring release mechanism. In order to establish the inclination of the backrest holder relative to the seat carrier, it is connected to both the base body in a hinge-like manner and provided with restraining means which maintain the instantaneous inclination setting for the backrest and / or the seat surface.
15 Ved disse kendte sædebærere anses det imidlertid som ugunstigt, at det ved indstilling af ryglæn- og/eller sædefladehældningen gælder, at disse bevæger sig meget afvigende fra hinanden, hvorved en siddende person eksempelvis får forrykket sin beklædning (skjorte-20 optrækningseffekt), eller der bibringes den siddende person en ubehagelig fornemmelse. Også det forslag at gøre siddefladens hældning indstillelig opfattes som ukomfortabelt og forhindrer indstillingen af en ergonomisk siddestilling.15 However, in the case of these known seat carriers, it is considered unfavorable that when adjusting the backrest and / or seat surface inclination, they move very differently from one another, whereby a seated person may, for example, shift his clothing (shirt-20 pull-up effect), or there is an unpleasant feeling to the seated person. Also, the suggestion of adjusting the inclination of the seat surface is perceived as uncomfortable and prevents the setting of an ergonomic sitting position.

Til grund for opfindelsen ligger følgelig den opgave at videreudvikle en sædebærer af kendt udførelse således, at disse effekter ikke længere optræder, og at sædebæreren derudover selv funktionelt udgør en sluttet enhed, der kun kræver ringe vedligeholdelse og tillader 30 en totalt set let bevægelse af funktionsdelene i forhold til hinanden ved indstilling over et stort indstillingsområde .Accordingly, the object of the invention lies in the further development of a seat carrier of known embodiment such that these effects no longer occur and that the seat carrier itself also functionally constitutes a closed unit which requires little maintenance and permits a total easy movement of the functional parts. relative to each other when adjusting over a large setting range.
Fra US-A-3402964 kendes en drejestol med et grundlegeme.sædepladeholder og ryglænbærer. Stolen om-35 fatter endvidere en torsionsfjeder og det amerikanske DK 166798 B1 3 patentskrift vedrører navnlig justering af fjederens spænding. Sædepladeholderen og ryglænbæreren kan vippe uafhængigt, idet grundlegemet og ryglænbæreren ikke er indbyrdes forbundet direkte ved hjælp af et i forhold 5 til den ene af disse to dele ubevægeligt element, men ved hjælp af et mellemled. Stolen er således behæftet med de ovennævnte ulemper.From US-A-3402964 a swivel chair with a basic body seat plate holder and backrest carrier is known. The chair further comprises a torsion spring and the US patent specification relates in particular to adjusting the tension of the spring. The seat plate holder and the backrest carrier can tilt independently, the base body and the backrest carrier not being interconnected directly by means of a movable element in relation to one of these two parts, but by means of an intermediate joint. Thus, the chair has the disadvantages mentioned above.
Ifølge den foreliggende opfindelse løses opgaven ved en sædebærer af den indledningsvis omhandlede art, TO som er særegen ved, at ryglænbæreren har en yderligere tværbolt, som er indrettet neden og tilbageskudt for den første tværbolt, og at der mellem grundlegemet og sædepladeholderen er anbragt en fjeder, hvorved fjederkraften trykker grundlegemet og sædepladeholderen fra 15 hinanden.According to the present invention, the task is solved by a seat carrier of the kind initially referred to, TO, which is peculiar in that the backrest carrier has an additional cross bolt which is arranged below and retracted for the first cross bolt and that a spring is arranged between the base body and the seat plate holder. , whereby the spring force pushes the base body and seat plate holder apart.
Fordelagtige udførelsesformer for opfindelsen fremgår af underkravene.Advantageous embodiments of the invention are apparent from the subclaims.
Som følge af disse foranstaltninger skabes der en sædebærer, som både løser den stillede opgave på for-20 delagtig måde og konstruktivt og fremstillingsteknisk kan udføres på enkel måde og tilmed har en høj stabilitet. Opdelingen af sædebæreren i enkelte funktionsdele muliggør tilmed en optimering af hældningsindstillingsfunktionen, hvorved denne som følge af sin enkle hånd-tering på den ene side og den behagelige fornemmelse på den anden side gerne accepteres af brugere.As a result of these measures, a seat carrier is created which satisfies both the required task in an advantageous manner and can be constructed in a simple manner in a constructive and manufacturing manner and also has a high stability. The division of the seat carrier into individual functional parts also allows optimization of the tilt adjustment function, whereby, due to its simple handling on the one hand and the pleasant feeling on the other hand, it is welcome by users.
En særlig udførelsesform for opfindelsen er ejendommelig ved, at den U-formede ryglænbærer med sit øvre endeområde er fastgjort på hængsellignende måde til sæ-30 depladehoIderen og med sit nedre endeområde af de lodrette dele er fastgjort på hængsellignende måde til det U-formede grundlegeme og ligesom sædepladeholderen har en tværbolt, hvormed lameller med kulisseføringer er hængselforbundet, hvilke lameller er forskydelige om en 35 fælles tredje tværbolt i grundlegemet.A particular embodiment of the invention is characterized in that the U-shaped backrest carrier is secured with its upper end region in a hinge-like manner to the seat plate holder and with its lower end region of the vertical parts in a hinge-like manner to the U-shaped base body and just as the seat plate holder has a transverse bolt with which hinged slats are hinged, which slides are displaceable about a common third transverse bolt in the basic body.
DK 166798 B1 4DK 166798 B1 4
En videreudvikling af denne opfindelse er ejendommelig ved, at lamellerne er udført strimmelformet, lagt skiftevis over hinanden og med deres kulisseføringer kan forskydes ind over hinanden ved en relativ bevægelse om-5 kring tværbolten.A further development of this invention is peculiar in that the slats are strip-shaped, arranged alternately over one another and with their backstops can be displaced over one another by a relative movement about the cross bolt.
Endvidere kan tværbolten samtidigt optage tilspæn-dingsorganet til kraftsluttende forbindelse af lamellerne med hinanden og med grundlegemet mod kraften af en mellem grundlegemet og sædepladeholderen indsat skrue-^ fjeder.Som forbedring af denne opfindelseside kan tværbolten hensigtsmæssigt være udformet som en bøsning, gennem hvilken der er ført en stang, der ved sin ene ende har en gevindmøtrik og mellem gevindmøtrikken og den yderste lamel optager en spændbøsning, mens den mod-'D satte ende er ombukket 180 C og til drejningssikring af stangen er ført ind i en udboring på grundlegemet og mellem den yderste lamel og 180^-bukningen igen bærer en spændbøsning. Her kan der om tværbolten være lagt en formdel, som tjener til arretering af en til højdeind- 20 stilling tjenende arm.Furthermore, the cross-bolt can simultaneously receive the clamping means for force-closing connection of the slats with each other and with the base body against the force of a screw spring inserted between the base body and the seat plate holder. As an improvement of this invention, the cross-bolt may conveniently be designed as a sleeve through which guided a rod having at one end a threaded nut and between the threaded nut and the outer slab taking up a clamping bush, while the opposite end is folded 180 ° and for turning the rod into a bore on the base body and between the outer slat and the 180 ^ bend again carry a clamping bush. Here, a molding member may be placed about the cross bolt which serves to secure an arm serving for height adjustment.
De strimmelformede lameller ifølge opfindelsen er enkle at fremstille, de kræver kun meget lidt plads på den monterede sædebærer, og de har kun en ringe vægt.The strip-shaped slats according to the invention are simple to manufacture, they require very little space on the mounted seat carrier and have only a small weight.
Kulisseføringerne i disse strimmelformede lameller kryd-25 ser sig om den fælles tredje tværbolt og tillader som følge af de langt indskårne kulisseføringer en forholdsvis stor bevægelsesgrad. Endvidere muliggøres med lameller af denne art som forbindelsesled mellem funktionsdelene differentierede bevægelsesforløb for funktions-30 dele. Funktionsdelenes bevægeIsesforløb foregår ved udløsning af tilspændingsorganet alene ved hjælp af de indsatte skruefjedre. Det er en yderligere fordel, at den tredje tværbolt samtidigt optager tilspændingsorganet i form af en gennemgående stang, der er lejret i ^ bøsninger.The backing guides in these strip-shaped slats cross the common third cross bolt and, as a result of the long cut back guides, allow a relatively high degree of movement. Furthermore, with slats of this kind, as a link between the functional parts, different movement processes for functional parts are made possible. The movement of the functional parts takes place by releasing the clamping means only by means of the inserted spring springs. It is a further advantage that the third cross bolt simultaneously accommodates the tightening means in the form of a through rod which is housed in bushings.

15 Sædebæreren 1 ifølge opfindelsen dannes i det væ sentlige af tre funktionsdele, af hvilke den ene udgør grundlegemet 3, en yderligere funktionsdel udgør sæde-pladeholderen 2, og endnu en funktionsdel udgør ryglænbæreren 4. Alle funktionsdele er af hensyn til 20 styrken fortrinsvis fremstillet af U-formede profiler og forbundet med hinanden over ledforbindelser 5. Grundlegemet 3, som udgør sædebæreren 1's basisdel, er ved sin frit udragende ende forsynet med en konisk støtte 6, hvori en konus på siddemøblets støtteben 25 15 griber ind på kraftsluttende måde. Den anden ende af dette grundlegeme 3 er ved hjælp af tværbolten 5 tilsluttet sædepladeholderen 2 på hængsellignende måde, og denne er igen forbundet på hængsellignende måde med ryglænbæreren 4. Som følge af denne hængsel-20 lignende forbindelse mellem funktionsdelene 2-4 kan sædebæreren 1 ved hældning af denne indstilles således, at der næppe optræder nogen forskydningsvirkning mellem delene, og ryglænet dermed heller ikke udsættes for nogen forskydningsvirkning i forhold til sædefladen.The seat carrier 1 according to the invention is formed essentially of three functional parts, one of which constitutes the base body 3, an additional functional part constitutes the seat plate holder 2, and another functional part constitutes the backrest carrier 4. All functional parts are preferably made of U-shaped profiles and connected to each other over articulated joints 5. The base body 3, which forms the base part of the seat carrier 1, is provided at its freely projecting end with a tapered support 6, in which a cone on the support leg 25 of the seating furniture engages in a force-closing manner. The other end of this basic body 3 is connected to the seat plate holder 2 in a hinge-like manner by means of the cross-bolt 5, and this is again connected in a hinge-like manner to the backrest carrier 4. As a result of this hinge-like connection between the functional parts 2-4, the seat carrier 1 can at the inclination thereof is adjusted so that there is hardly any shear effect between the parts, and thus the backrest is also not exposed to any shear effect relative to the seat surface.
25 Til sikring af denne effekt er de enkelte funktionsdele 2-4 forbundet med hinanden over et forbindelsesled 7, DK 166798 B1 6 nemlig således, at kinematikken bliver mulig, og forbindelsesleddet 7 er fikseret på mindst én funktionsdel 2,4 og ført bevægeligt på en yderligere funktionsdel 3.To ensure this effect, the individual functional parts 2-4 are connected to one another over a connecting link 7, namely, so that the kinematics becomes possible and the connecting link 7 is fixed to at least one functional part 2.4 and movable on a additional function part 3.
5 Forbindelsesleddet 7, der kan være udformet som en trekantet lamelpakke, er med sine to endepunkter fastgjort til ryglænbæreren 4 og til sædepladeholde-ren 2 over bolte 8, 9. Det tredje endepunkt af denne lamelpakke er forsynet med en kulisseføring 10 og 10 ført bevægeligt på en bolt 11 på grundrammen 3. Som følge af denne forbindelse mellem funktionsdelene 2-4 kan en bevægelse af ryglænbæreren 4 finde sted om dens hængselpunkt 8 på sædepladeholderen 2, således at det gælder, at ved hældning af den på sædep ladeholderen ^ hvilende siddeflade 14 følger ryglænbæreren 4 synkront med.5 The connecting link 7, which can be formed as a triangular lamella package, is secured with its two end points to the backrest carrier 4 and to the seat plate holder 2 over bolts 8, 9. The third end point of this lamella package is provided with a backing guide 10 and 10 on a bolt 11 on the base frame 3. As a result of this connection between the functional parts 2-4, a movement of the backrest carrier 4 can take place about its hinge point 8 on the seat plate holder 2, so that when tilting the seat surface resting on the seat plate holder 14 follows the backrest carrier 4 synchronously.
Analogt til anvendelsen af lamelpakken kunne der her også findes et andet forbindelsesled 7.Analogous to the use of the lamella package, there could also be another connection link 7 here.
Et sådant forbindelsesled 7 kunne eksempelvis væ-20 re en udliggerarm som vist i fig. 2, som udgør en forlængelse af ryglænbæreren 4. Denne udliggerarm 12 har hængselpunktet 8 til sædepladehoIderen 4 og bærer i sin forlængelse, dvs. ved sin frie ende, kulisseføringen 10, som omslutter grundlegemet 3's tvær-9 RSuch a connecting link 7 could, for example, be an extension arm as shown in FIG. 2, which is an extension of the backrest carrier 4. This extension arm 12 has the hinge point 8 of the seat plate holder 4 and carries in its extension, ie. at its free end, the backing 10, which encloses the transverse-9 R of the base body 3
bolt 11. Det tredje hængselpunkt på ryglænbæreren 4 kan i et sådant tilfælde bortfalde eller føre en mellemkoblet lamelpakke.bolt 11. The third hinge point of the backrest carrier 4 may in such case lapse or carry an interconnected lamella package.
Forbindelsesleddet 7, der kan være udført som lamelpakke, som udliggerarm 12 eller som en anden for- 30 bindelsesdel, kan være beliggende på kun den ene side af sædebæreren 1 eller symmetrisk om dennes længde-midterakse X. Den symmetriske udførelse er for så vidt fordelagtig, som den sikrer en bedre føring af funktionsdelene 2-4 i forhold til hinanden. Med hen-^ blik på at bringe funktionsdelene 2-4 i en udgangsstilling kan der mellem grundlegemet 3 og sædeplade- DK 166798 B1 7 holderen 2 findes en fjeder 17 med to ben. En yderligere fjeder 16 med to ben findes af de samme årsager mellem ryglænbæreren 4 og sædepladeholderen 2.The connecting link 7, which may be designed as a lamella package, as a protruding arm 12 or as another connecting part, may be located on only one side of the seat carrier 1 or symmetrical about its longitudinal center axis X. The symmetrical design is advantageous as far as possible. , which ensures better guidance of the functional parts 2-4 relative to each other. With a view to bringing the functional parts 2-4 into an initial position, a spring 17 with two legs can be found between the base body 3 and the seat plate holder 2. An additional two-leg spring 16 is provided for the same reasons between the backrest carrier 4 and the seat plate holder 2.
Kraftbindingen i lamelpakken 7 sker på den måde, 5 at der findes en forskruning 13 på sædebæreren 1 , som presser lamellerne mod hinanden, fortrinsvis i kulisseføringen 10 ' s område.The force bonding in the lamella package 7 takes place in the way 5 that there is a screw 13 on the seat carrier 1 which presses the lamellae against each other, preferably in the area of the backing liner 10.
I stedet for forskruningen 13 kan også en fjeder bevirke kraftbindingen, idet denne til stadighed udøver 10 sin kraft på lamellerne 7 og kun til udløsning af disse ophæver denne kraft.In place of the screw 13, a spring can also effect the force-bonding, since it constantly exerts its force on the louvers 7 and only to release them the force is removed.
Udløsning af forskruningen hhv. tilspændingsorganet 13 bevirker, at funktionsdelene 2,3,4 som følge af de mellemkoblede fjedre 16, 17 automatisk foretager 15 en hældningsindstilling. Den af brugeren ønskede position arreteres ved hjælp af tilspændingsorganet 13.Release of the screws, respectively. the clamping means 13 causes the function parts 2,3,4 to automatically make a tilt adjustment due to the interconnected springs 16, 17. The position desired by the user is arranged by means of the clamping means 13.
I figurerne 5 og 6 består sædebæreren 18 i det væsentlige af en vandret forløbende sædepladeholder 19, et dermed ved hjælp af en tværbolt 22 hængselforbundet 20 grundlegeme 20 og en ryglænbærer 21 , som ved hjælp af en øvre tværbolt 24 er hængselforbundet med sædepladeholderen 19 og ved hjælp af en nedre tværbolt 25 er hængselforbundet med grundlegemet 20.In Figs. 5 and 6, the seat carrier 18 consists essentially of a horizontally extending seat plate holder 19, a hinge member 20 by means of a cross bolt 22 and a backrest support 21 which is hingedly connected to the seat plate holder 19 by means of an upper cross bolt 24. by means of a lower cross bolt 25, the hinge is connected to the base body 20.
25 Ryglænbæreren 21 har ved sit nedre endeområde forlængede lodrette stykker 34.The backrest carrier 21 has extended vertical pieces 34 at its lower end region.
Grundlegemet 20 forløber nedefter fra sædepladeholderen 19 under dannelse af en spids vinkel med denne og i retning mod ryglænbæreren 21. Grundlegemet 30 20 har ved sin nederste ende støtten 23. Ryglænbæ reren 21 har i sin bageste forlængelse den egentlige bærer 33 til fastgørelse af et ikke nærmere vist ryglæn. Ryglænbæreren 21 og bæreren 33 kan i den enkleste form skrues sammen med hinanden.The base body 20 extends downwardly from the seat plate holder 19 to form a pointed angle thereto and towards the backrest carrier 21. The base body 20 20 has at its lower end the support 23. The backrest carrier 21 has in its rear extension the actual carrier 33 for attaching a more specifically the backrest. The backrest carrier 21 and carrier 33 can be screwed together in the simplest form.
35 Til sædepladeholderen er der på en tværbolt 26 ophængt strimmelformede lameller 29 med en kulisseføring 31. Yderligere strimmelformede lameller 28 DK 166798 B1 8 med en kulisseføring 30 er fastgjort om en tværbolt 27 på ryglænbæreren 21. Lamellerne 29 og 28 omslutter med deres kulisseføringer 30 og 31 den fælles bolt 25 og er lagt skiftevis oven på hinanden.35 On the seat plate holder, strip-shaped slats 29 are mounted on a transverse bolt 26 with a backing guide 31. Additional strip-shaped slats 28 with a backing guide 30 are fixed about a cross-bolt 27 on the backrest carrier 21. The slats 29 and 28 enclose with their backstops 30 and 31, the common bolt 25 is mounted alternately on top of one another.
5 Den fælles tværbolt 25 udgøres i princippet af en stang 36, som hører til tilspændingsorganet 35 og tjener til udløsning og til kraftsluttende forbindelse af de skiftevis over hinanden lagte lameller. Til dette formål har stangen 36 ved sin yderste ende et gevind, 10 som bærer en gevindmøtrik 37. Mellem den yderste lamel 28 og gevindmøtrikken 37 er der indsat en spændbøs-ning 38. En yderligere spændbøsning 40 findes på den modsatte side mellem den der yderst beliggende lamel 28 og en 180°-bukning af stangen 36. Stangen 36's 15 o endestykke griber efter 180 -bukningen til drejningssikring af tilspændingsorganet 35 ind i en passende udboring 39 i grundlegemet 20. Mellem sædepladehol-deren 19 og grundlegemet 20 findes der to ved siden af hinanden beliggende skruetrykfjedre 32, som hensigtsmæssigt ved hjælp af skruebolte holdes i den indsatte position.5 The common transverse bolt 25 is in principle formed by a rod 36 which belongs to the clamping means 35 and serves to release and to force-connect the alternately superposed slats. For this purpose, the rod 36 has at its outer end a thread 10 carrying a threaded nut 37. Between the outer lamina 28 and the threaded nut 37, a tensioning bushing 38 is inserted. A further tightening bushing 40 is located on the opposite side between the outermost located lamina 28 and a 180 ° bend of rod 36. The end of rod 36 of rod 36 engages, after 180 bend, to pivotably secure tightening member 35 into a suitable bore 39 in base body 20. Between the seat plate holder 19 and base body 20, two next to each other screw compression springs 32 which are conveniently held in the inserted position by means of screw bolts.
Løsning af gevindmøtrikken 37 på tilspændingsorganet 35 bevirker, at kraftbindingen mellem de om bol-ten 25 over hinanden laminerede lameller 28 og 29 på begge sider af sædebæreren 18 ophæves. Derved muliggøres nu en bevægelse af grundlegemet 20 i retning mod skruetrykfjederen 32's kraft hhv. af sædepladehol-deren 19 i retning mod grundlegemet 20. På den anden side muliggøres imidlertid navnlig en sænkning af ryglænbæreren 21 sammen med bæreren 33 fra den i fig.Loosening of the threaded nut 37 on the tightening means 35 causes the force bond between the laminations 28 and 29 laminated to each other across the bolt 25 to be abolished on both sides of the seat support 18. In this way, a movement of the base body 20 in the direction towards the force of the spring compression spring 32 is now possible. of the seat plate holder 19 in the direction of the base body 20. On the other hand, however, in particular, a lowering of the backrest carrier 21 together with the carrier 33 of the embodiment of FIG.
5 viste stilling bagud-nedefter. Derved indtager ryglænet: en af brugeren ønsket stilling og holdning. Denne svingning af ryglænbæreren 21 sker sammen med den vandrette ^ sædepladeholder 19 om tværbolten 22, hvorhos de to5 downwards. Thereby, the backrest occupies: a position and attitude desired by the user. This oscillation of the backrest carrier 21 occurs together with the horizontal seat plate holder 19 about the cross bolt 22, wherein the two
