Abstract

A vehicle seat comprising a seat frame (20) articulatedly connected by a first articulation (70) to a longitudinal forward sliderail (36) and articulatedly connected by a second articulation (72) to a backrest frame (40). The backrest frame (40) is articulatedly connected at its lower end by a third articulation (74) to at least one longitudinal rear sliderail (52). At least one of the articulations (70, 72, 74) has a circular cylindrical sleeve element (80) supported about a circular stemlike element (84), which elements (80, 84) have a rubber bushing (82) arranged permanently between them. The invention reduces the risk of play at the articulations of the frame structure.

Description

25 30 35 530 343 2 Ryggstödsramen 40 innefattar två på avstånd fràn varandra anordnade, långsträckta, parallella, huvudsakligen vertikalt lutande ryggstödsbalkar eller -stolpar 42 anpassade att uppbära ett ryggstöd (ej visat). The backrest frame 40 comprises two spaced apart, elongate, parallel, substantially vertically inclined backrest beams or posts 42 adapted to support a backrest (not shown).

Ryggstödsramen 40 är vidare i ryggstödsstolparnas 42 nedre ändar ledbart lagrad (C) i var sin led 74 i bakre glidskenor 52 som glider i icke visade styrskenor fästa i fordonets golvkonstruktion 100.The backrest frame 40 is further articulated in the lower ends of the backrest posts 42 (C) in each joint 74 in rear slide rails 52 which slide in guide rails (not shown) attached to the floor construction 100 of the vehicle.

Sätesramen 20 är vidare ledbart, kring en första horisontell tvärgående axel, fäst (B) i två leder 72 vid ryggstödsramen 40 genom var sitt fästelement 50 som är uppåt och nedåt glidbart fästa på vardera ryggstödsbalken 42. l mitten av sätesramen 20 i en icke visad tvärstång är en led 76 för ledbart fäste (D) anordnad för ett pneumatiskt ställdon 60 av kolv-cylindertyp eller bälgtyp vars nedre ände är ledbart, kring en andra horisontell tvärgående axel, fäst (E) i en led 78 på en främre glidskena 36, vilket ställdon 60 i övrigt fungerar som en gasfjåder kring vilken sätesramens 20 lutning är inställbar. Den främre glidskenan 36 är anpassad för att glidande upptas i en främre inte visad styrskena anordnad ifordonets golvkonstruktion 100.The seat frame 20 is further articulated, about a first horizontal transverse axis, fixed (B) in two joints 72 to the backrest frame 40 by each fastening element 50 which is slidably up and down on each backrest beam 42. In the middle of the seat frame 20 in a position not shown crossbar is a hinge 76 for articulated bracket (D) arranged for a pneumatic actuator 60 of piston-cylinder type or bellows type whose lower end is articulated, around a second horizontal transverse shaft, fastened (E) in a hinge 78 on a front slide rail 36, which actuator 60 otherwise functions as a gas spring around which the inclination of the seat frame 20 is adjustable. The front slide rail 36 is adapted to be slidably received in a front guide rail (not shown) arranged on the floor construction 100 of the vehicle.

En vertikal teleskopisk stång 30 i två delar är med sin övre rörformiga del 34 ledbart, kring en tredje horisontell tvärgående axel, fäst (A) i sätesramen 20. Den nedre delen 32 som är koaxiellt invändigt anordnad i den övre rörformiga delen 34 är fäst i den främre glidskenan 36.A vertical telescopic rod 30 in two parts is hinged with its upper tubular part 34, about a third horizontal transverse axis, fixed (A) in the seat frame 20. The lower part 32 which is coaxially arranged internally in the upper tubular part 34 is fixed in the front slide rail 36.

En utföringsform av de ovan nämnda lederna 70-78 visas i Fig. 2 användande hänvisningsbeteckningarna i samband med leden 70 även om de övriga lederna 72-78 kan vara utförda på motsvarande sätt.An embodiment of the above-mentioned joints 70-78 is shown in Fig. 2 using the reference numerals in connection with the joint 70, although the other joints 72-78 may be designed in a corresponding manner.

I Fig. 2 visas således ett område (A) för leden 70 där den övre rörfonniga stångdelen 34 är ledbart förbunden med sätesramen 20. Leden 70 innefattar en på änden av stångdelen 34 tvärgående vågrätt anordnad cirkulärt cylindrisk ledhylsa 80. På innerväggen av denna ledhylsa 80 är fäst en cirkulärt cylindrisk bussning 82 av ett gummimaterial eller ett material med motsvarande elastiska egenskaper. Bussningens 82 mantelyta kan vara fastvulkaniserad på innerväggen av ledhylsan 80 eller fäst på mekaniskt sätt med t.ex. utsprång på bussningsytan och fördjupningar i ledhylsans inneryta eller tvärt om.Fig. 2 thus shows an area (A) of the hinge 70 where the upper tubular rod part 34 is hingedly connected to the seat frame 20. The hinge 70 comprises a circular cylindrical hinge sleeve 80 arranged horizontally at the end of the rod part 34. On the inner wall of this hinge sleeve 80 is attached a circular cylindrical bushing 82 of a rubber material or a material with corresponding elastic properties. The mantle surface of the bushing 82 can be fixed vulcanized on the inner wall of the joint sleeve 80 or fixed mechanically with e.g. protrusions on the bushing surface and depressions in the inner surface of the joint sleeve or vice versa.

Bussningens 82 innerryta är fäst på mantelytan hos en inre leddel 84 pà motsvarande sätt som ovan, genom fastvulkanisering eller mekanisk låsning enligt ovan.The inner surface of the bushing 82 is attached to the mantle surface of an inner hinge portion 84 in the same manner as above, by solid vulcanization or mechanical locking as above.

Den inre leddelen 84 kan vara en del av sätesramen 20 eller en separat del fäst på denna.The inner hinge portion 84 may be a portion of the seat frame 20 or a separate portion attached thereto.

Bussningen 82 monteras spänningsfri så att de i leden 70 ledade delarna, den övre rörformiga stångdelen 34 och sätesramen 20, då är i ett önskat utgångsläge.The bushing 82 is mounted without tension so that the parts articulated in the joint 70, the upper tubular rod part 34 and the seat frame 20, are then in a desired initial position.

De andra lederna 72, 74, 76 och 78 är som tidigare nämnts ovan utförda på motsvarande sätt. Motsvarigheten till den cirkulärt cylindriska ledhylsan 80 sitter i leden 72 företrädesvis på ryggstödsbalkarna 42 och i leden 76 på ställdonets 60 övre ände. Genom 10 530 343 3 bussningarnas 70, 72, 74, 76, 78 torsionsfjäderegenskaper kan fordonstolens normalläge väljas genom att leden monteras med lämpliga vinkelförhållanden mellan de i leden ingående parterna. Eftersom bussningen då är spånningslös kommer den att sträva efter att återta detta läge. D.v.s. fordonsstolen kan ges ett utgångsläge exempelvis rätt uppstàende eller i ett ändläge.The other joints 72, 74, 76 and 78 are, as previously mentioned above, designed in a corresponding manner. The equivalent of the circularly cylindrical hinge sleeve 80 is located in the hinge 72, preferably on the backrest beams 42 and in the hinge 76 on the upper end of the actuator 60. By the torsion spring properties of the bushings 70, 72, 74, 76, 76, 78, the normal position of the vehicle seat can be selected by mounting the joint with suitable angular ratios between the parts included in the joint. Since the bushing is then voltage-free, it will strive to regain this position. I.e. the vehicle seat can be given a starting position, for example the correct standing or in an end position.
