Abstract

The backrest frame (40) has a resiliently compressible cylinder-rod extension (46) for pivoting to the seat bottom support (30) by a horizontal transverse axis (C) which is separate from forward and rearward horizontal transverse axes (A,B) about which the seat cushion frame (20) and the backrest frame are pivoted to the seat bottom support. The rod extension is a segment of the cylinder rod assemblies (42,48,50,52).

Description

[0007] [0007]

[0008] 528- 475 2/6 Den fjäderupphängning som tillhandahålls av den eftergivligt samman- .pressbara ryggstödsförlängningen gör sätesramen svängbar endast om- h kring den främre leden vid det undre sätesstödet. Den främre ändenavsä- ~ tet eller sitsdynan kommer därmed att utsättas för endast obetydliga rörel- ser som inte negativt påverkar förarens underben, medan de bakre delar- na av sätet. kan svänga avsevärt uppåt och nedåt. Fördelaktigt för trafiksä- kerheten är även att förarens huvud och ögon inte kommer att röra sig lika mycket uppåt och nedåt som i ett konventionellt svängande tjäderupp- hängt säte; förarens huvud och ögon kommer snarare att följa en platt övre sektion av en cirkelbàge som har sin medelpunkt vid ovannämnda främre led.528- 475 2/6 The spring suspension provided by the resiliently compressible backrest extension makes the seat frame pivotable only about the front joint at the lower seat support. The front end seat or seat cushion will thus be exposed to only insignificant movements that do not adversely affect the driver's lower legs, while the rear parts of the seat. can swing significantly up and down. It is also advantageous for road safety that the driver's head and eyes will not move as much upwards and downwards as in a conventional swinging capercaillie-suspended seat; the driver's head and eyes will rather follow a flat upper section of a circular arc having its center at the above - mentioned front link.

Ryggstödsramens stöd som tillhandahålls av förlängningen; tillåter att ryggstödsramen fönnår motstå avsevärda kollisionskrafter samt säkert » fasthålla en hög fästpunlct för ett säkerhetsbälte. The backrest frame support provided by the extension; allows the backrest frame to withstand significant collision forces and securely »maintain a high fastening point for a seat belt.

[0023] Den på ritningama visade sâtesramkonstruktionen 10 innefattar en sits- eller sätesram 20, ett undre sätesstöd 30 och en ryggstödsram 40.The seat frame construction 10 shown in the drawings comprises a seat or seat frame 20, a lower seat support 30 and a backrest frame 40.

I det som exempel i Fig. 1 visade modellutförandet innefattar såtesramen 20 ett par på avstånd anordnade, långsträckta, huvudsakligen horisontella stänger 22 anordnade att understödja en sätesdyna 24.In the exemplary embodiment shown in Fig. 1, the seat frame 20 comprises a pair of spaced apart, elongate, substantially horizontal bars 22 arranged to support a seat cushion 24.

Det undre sätesstödet 30 innefattar ett ramverk som även inkluderar ett par på avstånd anordnade längsgående stänger 32 förbundna med re- spektive främre vertikala stänger 34 och inbördes förbundna genom ett an- tal tvärgående stänger 38. Lufande stag eller strävar 36, som sträcker sig mellan respektive längsgående och vertikala stänger 32 och 34, verkar som stöd för de vertikala stångerna 34.The lower seat support 30 includes a framework which also includes a pair of spaced longitudinal bars 32 connected to respective front vertical bars 34 and interconnected by a plurality of transverse bars 38. Ventilating struts or struts 36 extending between respective longitudinal and vertical bars 32 and 34, act as support for the vertical bars 34.

Ryggstödsramen 40 innefattar att par av på avstånd anordnade huvudsak- ligen vertikalt lutande ryggstödsbalkar- eller stolpar 42 som år inbördes förbundna genom en övre tvärgående stång 44 och anordnad att uppbära ett ryggstöd 54. l den utföringsfonn som visas på Fig. 1, har enligt uppfinningen ryggstöds- ramen 40 även en efterglvligt sammanpressbar förlängning 46. Förläng- ningen 46. som gör att ryggstödsrarrfen 40 fömtår motstå avsevärda fram- åf- och bakåtriktade krafter. innefattar ett par tlllbakadragbara stänger 48, såsom förskjutbart lagrade och nedåt, av tex. gasfiädrar fjäderpåverkade kolvstänger, i respektive ryggstödsstolpar 42, vilka därigenom bildar cy- lindrar för kolvstängema 48.The backrest frame 40 comprises that pairs of spaced apart substantially vertically inclined backrest beams or posts 42 which are interconnected by an upper transverse bar 44 and arranged to support a backrest 54. In the embodiment shown in Fig. 1, according to the invention the backrest frame 40 also has a subsequently compressible extension 46. The extension 46. which enables the backrest arm 40 to withstand considerable forward and backward forces. includes a pair of retractable rods 48, such as slidably mounted and downwardly, of e.g. gas fi springs spring-actuated piston rods, in respective backrest posts 42, which thereby form cylinders for the piston rods 48.

Som antyds i Fig. 2 och 3. kan varje kolvstång 48 altemativt vara inklude- rad i ett fiädrande såtesupphängningsaggregat liknande det som vanligen As indicated in Figs. 2 and 3, each piston rod 48 may alternatively be included in a resilient seat suspension assembly similar to that normally used.

Den tillbakadragbara förlängningen 46 behöver inte nödvändigtvis vara ' tillbakadragbar in i ryggstödsramen 40. Ett valfritt omvänt arrangemang av en upphängningsenhet 52 (Fig. 4) kan vara lämpligt i syfte att eventuellt omfördela volym, massa-och komponenter fràn ryggstödsstolpama 40 till det undre stödet 30.The retractable extension 46 need not necessarily be retractable into the backrest frame 40. An optional reverse arrangement of a suspension unit 52 (Fig. 4) may be appropriate in order to optionally redistribute volume, mass and components from the backrest posts 40 to the lower support 30. .

Medande visade utföringsforrnema har en dubbel förlängning 46, 46, skul- le detvara närliggande för en fackman att modifiera förlängningen till en enkel förlängning (ej visat).While the embodiments shown have a double extension 46, 46, it would be obvious to a person skilled in the art to modify the extension to a single extension (not shown).

Rear to the seat frame 20 pivotable about a transverse horizontal axis through joints B at the seat frame 40, more specifically at respective lower portions of the backrest posts 42. Finally, the extension 48 is pivotable about a third horizontal transverse axis through lower joints C, located below the seat frame 20. at the lower the support 30. more specifically at the respective rear end portions of the lower support 30.

Som framgår av de schematiska vyerna i Fig. 2-4, är det undre stödet an- passat för att vara glidbartförbundet med ett par glidskenor 62 (endast en visas) hos en golvkonstruktion 60 i en fordonshytt för att tillàta inställning framåt eller bakät av stolens ramkoristruktion' 10.As can be seen from the schematic views in Figs. 2-4, the lower support is adapted to be slidably connected to a pair of slide rails 62 (only one is shown) of a floor structure 60 in a vehicle cab to allow forward or rearward adjustment of the seat. frame correction '10.

To adjust the height of the rear end of the seat frame 20, the above-mentioned units 50 can be slidably accommodated in the respective backrest post 42 and movably adjustable along the rod 42 by another linear actuator (not shown). The latter height can also be set by varying, for example, a bias voltage (or volume) of the (gas) cap which acts on each rod 48 (not shown).
