Description
25 30 530 679 2 Enligt en betraktelse av uppfinningen har fordonsstolen ett flertal inbördes sväng- och förskjutbart förbundna delar som bildar en sitsram, ett främre understöd och en till ett bakre understöd förlängd ryggstödsram. De sväng- och förskjutbart förbundna delarna är genom fjäderkraft förspända i riktning mot ett utgångsläge hos stolen. Ett från utgångsläget awikande önskat sittläge, som kan vara åtminstone ett par av ett höjdläge hos sitsramen, en sitsvinkel hos sitsramen och en lutningsvinkel hos rygg- stödsramen, kan inställas simultant av en i stolen sittande person. Personen frigör då åtminstone en spärranordning som verkar på de förskjutbara delarna, utövar därpå en kraft mot fjäderkraften i riktning mot det önskade sittläget och låser slutligen spär- ranordningen eller -anordningarna. According to a consideration of the invention, the vehicle seat has a plurality of mutually pivotally and slidably connected parts which form a seat frame, a front support and an backrest frame extended to a rear support. The pivotally and slidably connected parts are biased by spring force in the direction of a starting position of the chair. A desired seating position deviating from the initial position, which may be at least a pair of a height position of the seat frame, a seat angle of the seat frame and an inclination angle of the backrest frame, can be adjusted simultaneously by a person sitting in the chair. The person then releases at least one locking device which acts on the displaceable parts, then exerts a force against the spring force in the direction of the desired sitting position and finally locks the locking device or devices.
Justering av den fjädrande och helsimultantjusterbara fordonsstolen börjar alltså med frikoppling av minst en spärrmekanism, vilket leder till att stolen kan justeras i en eller flera riktningar. Justeringen sker i jämvikt med kroppen genom användning av motverkande supportfjädrar, vilket gör att endast minimala muskelrörelser krävs.Adjustment of the resilient and fully-simultaneously-adjustable vehicle seat thus begins with disengagement of at least one locking mechanism, which means that the seat can be adjusted in one or fl your directions. The adjustment takes place in balance with the body through the use of counteracting support springs, which means that only minimal muscle movements are required.
Spärrmekanismen kan innefatta en elektrisk, hydraulisk eller pneumatisk spärr, var- vid till exempel en tryckluftskälla såsom en trycktank eller en kompressor används.The locking mechanism may comprise an electric, hydraulic or pneumatic lock, in which case, for example, a source of compressed air such as a pressure tank or a compressor is used.
Spärren är frikopplad antingen när tryck appliceras eller när tryck inte appliceras.The latch is disengaged either when pressure is applied or when pressure is not applied.
Fordonsstolen kan automatiskt justeras i höjdled, genom att tyngden varieras utanför ett normalintervall, det vill säga att den sittande personen reser sig respektive sätter sig ned bestämt, alternativt lyfter fötterna från golvet. Tyngdskillnader utanför interval- let, vilket kan definieras i förväg, identifieras av en kraftgivare i stolen, och leder till att stolen automatiskt höjs respektive sänks. Höjden justeras genom användning av en dynamisk eller statisk tryckfjäder.The vehicle seat can be automatically adjusted in height, by varying the weight outside a normal range, ie the seated person gets up or sits down firmly, or lifts his feet off the floor. Weight differences outside the range, which can be defined in advance, are identified by a power sensor in the chair, and lead to the chair being automatically raised or lowered. The height is adjusted by using a dynamic or static compression spring.
Fordonsstolens läge i längdled kan justeras genom att den dras framåt respektive bakåt av den sittande personen, varvid den förskjuts i minst en glidskena, till exempel med ett underskuret spår. Det förlängda ryggstödets lutning kan justeras kring en rör- lig led mot golvet.The longitudinal position of the vehicle seat can be adjusted by pulling it forwards and backwards, respectively, by the seated person, whereby it is displaced in at least one slide rail, for example with a undercut groove. The inclination of the extended backrest can be adjusted around a movable joint towards the floor.
Fordonsstolens sitsram är under användning svängbar omkring en led mellan en sits- ram och ett främre understöd, medan sitsramens bakre del kan fjädra i höjdled, vilket 10 15 20 25 30 530 G79 3 gör att läget för sitsramens främre del endast pâverkas minimalt. Positionen för föra- rens underben kommer därför att variera endast obetydligt, vilket minskar risken för påverkan pà broms- och gaspedaler. Detta är viktigt för att trafiksäkert kunna justera sittställningen under gång och är därmed viktigt för åkkomforten, inte minst under långa körningar.In use, the seat frame of the vehicle seat is pivotable about a joint between a seat frame and a front support, while the rear part of the seat frame can spring vertically, which means that the position of the front part of the seat frame is only minimally affected. The position of the driver's lower leg will therefore vary only insignificantly, which reduces the risk of impact on the brake and accelerator pedals. This is important in order to be able to safely adjust the sitting position while walking and is thus important for riding comfort, not least during long journeys.
Uppfinningen kommer nu att beskrivas mer i detalj med hänvisning till de bifogade figurerna. Utföringsformerna skall endast uppfattas som åskådliggörande den förelig- gande uppfinningens anda och omfång, och på inget som helst sett som en begräns- ning.The invention will now be described in more detail with reference to the accompanying figures. The embodiments are to be construed as merely illustrating the spirit and scope of the present invention, and are not to be construed as limiting in any way.
Kortfattad beskrivning av figurema FIG. 1 är en schematisk sidovy som visar stolen enligt den föreliggande uppfinning- en.Brief Description of the Figures FIG. 1 is a schematic side view showing the chair according to the present invention.
FIG. 2 är en vy av stolskonstruktionen snett ovanifràn, vari stolsregleringen och styr- systemet är inkluderade.FIG. 2 is a view of the chair construction obliquely from above, in which the chair control and the steering system are included.
Detal'|erad beskrivning av uggfinningen Utföringsforrnen enligt FlG.1 innefattar en sitsram 20 och två ryggstödsstolpar 42 som är sammanbundna till en ryggstödsram 40. De två ryggstödsstolparna 42 bildar cylindrar för kolvstänger 48, vilka kan vara fritt rörliga I cylindrarna och i förhållande till varandra. Ryggstödsramen 40 är således förskjutbari höjdled. Kolvstängerna 48 kan, som alternativ till den tryckfjäder 60 som kommer att beskrivas närmare i det föl- jande, vidare vara påverkade av en tryckfjäder bildad av en fjäder 60 i varje rygg- stödsstolpe 42, som antyds med streckprickade linjeri FIG. 2. Fjädrarna 60 kan utgö- ras av till exempel gastjädrar. Ryggstödsramen 40 är kopplad till sitsramen 20 genom en dubblerad svängled B. 10 15 20 25 30 530 679 4 Vid ett bakre understöd 50 finns en svängled C. Denna led C är fritt vridbar. Under- stödet 50 kan, då ryggstödsramen 40 löper ända ned till golvet, utgöras av en tvär- balk 54. Ryggstödsramens 40 nedre ände är förbunden till golvet 100 genom en glid- sko 52, vilken medelst en ryggstödstjäder 70 är förbunden till en med golvet 100 glid- bart förbunden glidsko 36 hos ett främre understöd 30. FlG. 2 visar hur stolen via glidskorna 36 och 52 är förskjutbart anordnad vid golvet 100, i detta fall via ett under- skuret spår 102. Glidskorna 36 och 52 kan emellertid på ej visat vanligare sätt löpa i glidskenor förbundna med golvet.DETAILED DESCRIPTION OF THE UNIT The embodiment according to Fig. 1 comprises a seat frame 20 and two backrest posts 42 which are connected to a backrest frame 40. The two backrest posts 42 form cylinders for piston rods 48, which can be freely movable in the cylinders and relative to each other. . The backrest frame 40 is thus displaceable in height. The piston rods 48 may, as an alternative to the compression spring 60 which will be described in more detail below, be further actuated by a compression spring formed by a spring 60 in each backrest post 42, which is indicated by dash-dotted lines FIG. 2. The springs 60 can be, for example, gas springs. The backrest frame 40 is connected to the seat frame 20 by a double pivot joint B. At a rear support 50 there is a pivot joint C. This joint C is freely rotatable. When the backrest frame 40 runs all the way down to the floor, the support 50 may be formed by a cross beam 54. The lower end of the backrest frame 40 is connected to the floor 100 by a sliding shoe 52, which by means of a backrest strut 70 is connected to one with the floor 100 slidably connected sliding shoe 36 of a front support 30. FlG. 2 shows how the chair is slidably arranged at the floor 100 via the sliding shoes 36 and 52, in this case via an undercut groove 102. However, the sliding shoes 36 and 52 can run in sliding rails connected to the floor in a manner not shown in a more common manner.
Sitsramen 20 är via en svängled A förbunden till ett främre understöd 30, vilket inne- fattar ett par med varandra förskjutbart förbundna delar, i det visade exemplet en cy- linder 34 och en kolvstång 32. Kolvstången 32 är orörligt fäst vid glidskon 36, vid vil- ken en undre ände av ovannämnda tryckfjäder 60 är ledad. Dess övre ände är ledad vid sitsramen 20 via en tvärgående ramdel 24. Denna ramdel 24 är lokaliserad mel- lan sitsramens främre respektive bakre kant, företrädesvis lett mittläge under den sittande personens tyngdpunkt. Tryckfjädern 60 är i det visade exemplet en gasfjä- der, såsom en kolv-cylinderenhet eller en ej visad gummibälg, vars tryck kan påver- kas av ett driv- och styrarrangemang 110 som kommer att närmare beskrivas längre fram. Vid sidan om den helsimultana inställningen enligt uppfinningen kan det med tryckfjädern 60 även vara möjligt att enbart inställa sitthöjden.The seat frame 20 is connected via a pivot joint A to a front support 30, which comprises a pair of parts slidably connected to each other, in the example shown a cylinder 34 and a piston rod 32. The piston rod 32 is immovably attached to the sliding shoe 36, at which a lower end of the above-mentioned compression spring 60 is articulated. Its upper end is articulated at the seat frame 20 via a transverse frame part 24. This frame part 24 is located between the front and rear edge of the seat frame, preferably slightly centered below the center of gravity of the seated person. The compression spring 60 in the example shown is a gas spring, such as a piston-cylinder unit or a rubber bellows (not shown), the pressure of which can be influenced by a drive and control arrangement 110 which will be described in more detail later. In addition to the fully simultaneous adjustment according to the invention, it may also be possible with the compression spring 60 to adjust only the seat height.
Framför det främre understödet 30 är en dragfjäder 74 anordnad, vilken är förbunden med ett golvfäste 78. De två fjädrama 70, 74, vilka kan men inte behöver vara pneu- matiska fjädrar, och det främre understödet 30 är försedda med spärranordningar 72, 76 resp. 38, av vilka minst en frikopplas vid justering av stolen 10. I det visade ex- emplet är, som antyds i FIG. 2, spärranordningarna 72, 76 och 38 pneumatiska, vilka då tryck appliceras kan vara anordnade att inta antingen ett spärrat eller icke spärrat läge. Varje spärranordning kan då innefatta t.ex. en ej visad kolv eller spärrhake som med friktion resp. formbundet ingrepp låser de inbördes förskjutbara delarna vid var- andra.In front of the front support 30 a tension spring 74 is arranged, which is connected to a floor bracket 78. The two spring frames 70, 74, which may but need not be pneumatic springs, and the front support 30 are provided with locking devices 72, 76 and . 38, of which at least one is disengaged when adjusting the chair 10. In the example shown, as indicated in FIG. 2, the locking devices 72, 76 and 38 are pneumatic, which when pressure is applied can be arranged to assume either a locked or non-locked position. Each locking device can then comprise e.g. a piston or pawl not shown which with friction resp. molded engagement locks the mutually displaceable parts next to each other.
I FIG. 2 visas även ett exempel på ovannämnda driv- och styrarrangemang 110 för stolen 10. 10 15 20 25 30 530 679 5 Tryckfiädern 60 är för höjdreglering av sitsramen 20 kopplad till en tryckkälla 110, till exempel en tryckbehållare eller en kompressor. Tryckkällan 112 är via en ledning 114 förbunden med en ventilenhet 116 som i sin tur styrs av en elektronisk styrenhet 128 via en signalledning 126.In FIG. 2 also shows an example of the above-mentioned drive and control arrangement 110 for the seat 10. The pressure spring 60 is for height adjustment of the seat frame 20 connected to a pressure source 110, for example a pressure vessel or a compressor. The pressure source 112 is connected via a line 114 to a valve unit 116 which in turn is controlled by an electronic control unit 128 via a signal line 126.
Ett önskat sittläge kan inställas ungefär enligt följande genom simultant kombinerade rörelser hos stolens rörliga delar orsakade av krafter utövade av en i stolen sittande person mot verkan av en sammansatt fjäderkraft som strävar att förspänna stolen mot ett utgångsläge, som kan vara ett fjäderändläge, t.ex. ett framåtriktat läge hos stolen, eller ett normalläge.A desired sitting position can be adjusted approximately as follows by simultaneously combined movements of the moving parts of the chair caused by forces exerted by a person sitting in the chair against the action of a composite spring force which seeks to bias the chair towards a starting position, which may be a spring end position, e.g. . a forward position of the chair, or a normal position.
Vid stolen 10 finns för den sittande personen tillgänglig en strömställare 132 med ett enda återtjädrande manöverorgan i form av en àterfjädrande tryckknapp134. När personen håller tryckknappen 134 nedtryckt skickas en signal till styrenheten 128 via en signalledning 130. Styrenheten 128 avger då via signalledningen 126 en signal till ventilenheten 116 att öppna förbindelsen från tryckkällan 1 12 till tryckledningar 1 18, 120 och 122, vilka är förbundna med ovan beskrivna respektive spärranordningar 72, 76 och 38.At the seat 10, a switch 132 with a single resilient actuator in the form of a resilient push button 134 is available for the seated person. When the person holds down the pushbutton 134, a signal is sent to the control unit 128 via a signal line 130. The control unit 128 then sends via the signal line 126 a signal to the valve unit 116 to open the connection from the pressure source 12 to pressure lines 11, 120 and 122, which are connected to the above. described respective locking devices 72, 76 and 38.
Därigenom frikopplas spärranordningarna. Det främre understödet 30 och ryggstöds- ramen 40 är då inbördes fritt förskjutbara. Sitsramens 20 lutning kan nu inställas ge- nom att understöden 30 och 40 ändrar läge i förhållande till varandra genom att den sittande personen flyttar sin tyngdpunkt framåt eller bakåt. Ej visad fjäder kan vara anordnad för att hålla sitsramen i ett ursprungsläge, t.ex. ett horisontalläge.Thereby the locking devices are disengaged. The front support 30 and the backrest frame 40 are then mutually freely displaceable. The inclination of the seat frame 20 can now be adjusted by the supports 30 and 40 changing position relative to each other by the seated person moving his center of gravity forwards or backwards. A spring (not shown) can be arranged to hold the seat frame in an original position, e.g. a horizontal position.
Den sittande personen kan samtidigt förskjuta hela stolen till önskat läge i längdled mot fjäderkraften av dragfjädern 74, och samtidigt även inställa lutningen av rygg- stödsramen 40 mot verkan av trycktjädern 70. När personen funnit den önskade sitt- ställningen frigör personen tryckknappen 134, så att spärranordningarna 72, 76 och 38 återgår till sina spärrade lägen och stolen låses i sitt därigenom inställda sittläge.The seated person can simultaneously move the entire chair to the desired position longitudinally against the spring force of the tension spring 74, and at the same time also adjust the inclination of the backrest frame 40 against the action of the push cap 70. When the person has found the desired sitting position, the person releases the push button 134 the locking devices 72, 76 and 38 return to their locked positions and the chair is locked in its sitting position thereby adjusted.
Som vidare framgår av FIG.2, kan även trycket i en tryckledning 124 till den pneuma- tiska tryckfjädern 60 styras av ventilenheten 118 på t.ex. följande sätt: 10 15 20 25 530 S79 6 En nedàtriktad kraft från den sittande personen på tryckfjädern 60 avkänns av en kraftgivare 62 för avkänning av en kraftkomponent hos kraften från den sittande per- sonen verkande på trycktjädern 60, Givaren 62 kan vara placerad t.ex. mellan sits- ramen 20 och tryckfjädern 60. Givaren 62 är vidare via en signalledning 136 förbun- den med styrenheten 128 för att kontinuerligt signalera ett värde på den nedåtriktade kraften till styrenheten 128 när strömställarens 132 tryckknapp 134 är nedtryckt. Om kraften understiger ett förinställt undre värde, indikerande att den sittande minskar kraften mot sitsramen 20 - dvs. reser sig obetydligt- avger styrenheten 128 en sig- nal till ventilenheten 116 att inkoppla tryckledningen 124 med tryckkällan 112 så att trycket stiger i tryckfjäden 60 och sitsramen höjs. När personen åter ökar kraften mot sitsramen 20, eller frigör den återfjädrande tryckknappen 134, stänger ventilenheten 116 förbindelsen mellan tryckledningen 124 och tryckkällan 112, så att sitsramen 20 stannar i sitt nya höjdläge. Om å andra sidan kraften överstiger ett förinställt övre värde, indikerande att den sittande ökar kraften mot sitsramen 20 - t.ex. genom att lätta sina fötter från golvet 100 - avger styrenheten 128 en signal till ventilenheten 116 att frikoppla tryckledningen 124 till atmosfären t.ex. via en ej visad strypning, så att trycket sjunker i tryckfjädern 60 och sitsramen sänks. När personen åter ökar kraf- ten mot sitsramen 20, eller frigör tryckknappen 134, stänger ventilenheten 116 för- bindelsen mellan tryckledningen 124 och atmosfären, så att sitsramen 20 äter stan- nari sitt nya höjdläge. Nämnda förinställda undre och övre värden på den nedåtrikta- de kraften finns lagrade i ett minne hos styrenheten 128 eller i en ej visad dator i for- donet och kan kalibreras t.ex. efter den sittande personens vikt.As further shown in FIG. 2, the pressure in a pressure line 124 to the pneumatic compression spring 60 can also be controlled by the valve unit 118 on e.g. the following method: 10 15 20 25 530 S79 6 A downward force from the seated person on the compression spring 60 is sensed by a force sensor 62 for sensing a force component of the force from the seated person acting on the pressure spring 60. The sensor 62 may be located t. ex. between the seat frame 20 and the compression spring 60. The sensor 62 is further connected via a signal line 136 to the control unit 128 to continuously signal a value of the downward force to the control unit 128 when the push button 134 of the switch 132 is depressed. If the force is less than a preset lower value, indicating that the occupant reduces the force against the seat frame 20 - ie. rises insignificantly, the control unit 128 sends a signal to the valve unit 116 to connect the pressure line 124 to the pressure source 112 so that the pressure rises in the pressure spring 60 and the seat frame is raised. When the person again increases the force against the seat frame 20, or releases the resilient push button 134, the valve unit 116 closes the connection between the pressure line 124 and the pressure source 112, so that the seat frame 20 remains in its new height position. If, on the other hand, the force exceeds a preset upper value, indicating that the occupant increases the force against the seat frame 20 - e.g. by lifting its feet off the floor 100 - the control unit 128 sends a signal to the valve unit 116 to disconnect the pressure line 124 to the atmosphere e.g. via a throttle (not shown), so that the pressure drops in the compression spring 60 and the seat frame is lowered. When the person again increases the force against the seat frame 20, or releases the pushbutton 134, the valve unit 116 closes the connection between the push line 124 and the atmosphere, so that the seat frame 20 eats permanently to its new height position. Said preset lower and upper values of the downward force are stored in a memory of the control unit 128 or in a computer (not shown) in the vehicle and can be calibrated e.g. according to the weight of the seated person.
