I fordonet forekommande fordonsstolar maste da vara sa konstruerade att de medger en fri passage f6r att mojliggora en snabb och effektiv evakuering av fordonet. 1 SYFTE MED UPPFINNINGEN Ett syfte med foreliggande uppfinning är att astadkonnnna en fordonsstol, som underlattar evakuering av en i fordonsstolen sittande person. In certain types of vehicles, such as off-road and combat vehicles, it is unfortunate to be able to quickly evacuate the vehicle in the event of danger. Vehicle seats present in the vehicle must then be so constructed that they allow a free passage to enable a quick and efficient evacuation of the vehicle. OBJECT OF THE INVENTION An object of the present invention is to provide a vehicle seat which facilitates the evacuation of a person sitting in the vehicle seat.
Ett ytterligare syfte med uppfinningen är att astadkomma en fordonsstol, som vid utrymningsbehov mojliggOr en snabb och effektiv evakuering av fordonet. A further object of the invention is to provide a vehicle seat which, in the event of a need for evacuation, enables a rapid and efficient evacuation of the vehicle.
Annu ett syfte med uppfinningen är att astadkomma en fordonsstol, som kan mano- vreras av bade forare och passagerare for aft underlatta evakuering av fordonet. Another object of the invention is to provide a vehicle seat which can be maneuvered by both drivers and passengers to facilitate evacuation of the vehicle.
SAMMANFATTNING AV UPPFINNINGEN Ovan angivna syften astadkommes med fordonsstolen enligt patentkrav 1. SUMMARY OF THE INVENTION The above objects are achieved with the vehicle seat according to claim 1.
Fordonsstolen kommer vid en utrymning av fordonet att medge fri passage, eftersom den manovrerbara fastanordningen i det andra laget är anordnad att frigora den minst ena linan fOr att nerfalla ryggstOdet. Nar ryggstOdet är nerfallt kommer en i fordonsstolen sittande person snabbt och enkelt kunna hjalpas ut ur fordonet utan att fordonsstolen utgor ett hinder. Samtidigit kommer fordonsstolen inte utgora ett hinder om medpassagerare forsoker lamna fordonet vid utrymningen. Den manovrerbara fastanordningen kan manovreras av bade den person som sitter i fordonsstolen och av andra personer i fordonet. Fordonsstolen kan exempelvis utgoras av en forarstol, som är avsedd for fordonets forare. For det fall fordonet är ett stridsfordon kan den enda mojliga utrymningsvagen ur fordonet vara bakat och forbi det utrymme som upptages av ryggstodet nar det är uppfallt. Darmed maste ryggstodet nerfallas for att nnojliggora utrynnningen. I det forsta, uppfallda laget är den nnanovrerbara fastanordningen anordnad att fasthalla den minst ena linan, sa att ryggstodet bildar ett stod for den i fordonsstolen sittande personen. In the event of an evacuation of the vehicle, the vehicle seat will allow free passage, since the manoeuvrable fastening device in the second layer is arranged to release the at least one rope in order to lower the backrest. When the backrest is folded down, a person sitting in the vehicle seat will be able to be helped out of the vehicle quickly and easily without the vehicle seat constituting an obstacle. At the same time, the vehicle seat will not be an obstacle if fellow passengers try to leave the vehicle during the evacuation. The manoeuvrable fixed device can be maneuvered by both the person sitting in the vehicle seat and by other persons in the vehicle. The vehicle seat can, for example, consist of a driver's seat, which is intended for the driver of the vehicle. In the event that the vehicle is a combat vehicle, the only possible evacuation trolley from the vehicle may be baked and past the space occupied by the backrest when it is noticed. Thus, the backrest must be lowered to make the thinning easier. In the first, conspicuous layer, the innovatable fixed device is arranged to hold the at least one rope, so that the backrest forms a stand for the person sitting in the vehicle seat.
Fordonsstolens ryggstod far enligt en utforingsform en mycket kompakt form i det nerfallda laget och är darmed inte i vagen for personal som skall ta sig ur fordonet vid evakuering. 2 Enligt en utf6ringsform av uppfinningen innefattar fastanordningen ett forsta manoverdon f6r att bringa fastanordningen till det andra laget och frig6ra den minst ena linan. Den manovrerbara fastanordningen kan manovreras av bade den person som sitter i fordonsstolen och av andra personer i fordonet. Vid en utrynnning av fordonet kan saledes ryggstodet snabbt och effektivt nerfallas sa att en i fordonsstolen sittande person eller andra personer i fordonet snabbt och enkelt kan evakueras ur fordonet utan att fordonsstolen utgOr ett hinder. According to an embodiment, the backrest of the vehicle seat has a very compact shape in the collapsed layer and is thus not in the way of personnel who have to get out of the vehicle during evacuation. According to an embodiment of the invention, the fastening device comprises a first actuator for bringing the fastening device to the second layer and releasing the at least one line. The manoeuvrable fixed device can be maneuvered by both the person sitting in the vehicle seat and by other persons in the vehicle. In the event of a dilution of the vehicle, the backrest can thus be lowered quickly and efficiently so that a person sitting in the vehicle seat or other persons in the vehicle can be quickly and easily evacuated from the vehicle without the vehicle seat constituting an obstacle.
Enligt en ytterligare utforingsform innefattar det forsta manoverdonet en forsta manoverspak, som styr fastanordningen via en kabel. Den forsta manoverspaken kan darmed placeras pa lamplig plats i forhallande till fordonsstolen. Rorelse och kraft fran manoverspaken over-fors via kabeln till fastanordningen. According to a further embodiment, the first actuator comprises a first actuator lever, which controls the fastening device via a cable. The first control lever can thus be placed in a suitable place in relation to the vehicle seat. Movement and force from the control lever are transferred via the cable to the fixed device.
Enligt en ytterligare utf6ringsform innefattar fastanordningen ett for den minst ena lman anordnat fastelement. Linan kan darmed effektivt forbindas med fastanordningen. According to a further embodiment, the fastening device comprises a fastening element arranged for the at least one person. The rope can thus be effectively connected to the fixed device.
Enligt en ytterligare utforingsform innefattar fastanordningen en sparrmekanism, som i det forsta laget sparrar fastelementet och i det andra laget frig& fastelementet. Linan kan darmed snabbt och effektivt frigoras fran fastanordningen genom att frigOra fastelementet medelst sparrelementet. According to a further embodiment, the fastening device comprises a locking mechanism, which in the first layer locks the fastening element and in the second layer the release & fastening element. The line can thus be quickly and efficiently released from the fastening device by releasing the fastening element by means of the spar element.
Enligt en ytterligare utf6ringsform innefattar fastanordningen en vridaxel pa vilken sparrmekanismen är anordnad. Genom att anordna sparrmekanismen pa vridaxeln kan fastanordningen utf6ras kompakt, vilket g6r fastanordningen mindre utrymmeskravande. According to a further embodiment, the fastening device comprises a pivot shaft on which the locking mechanism is arranged. By arranging the locking mechanism on the rotary shaft, the fastening device can be made compact, which makes the fastening device less space-consuming.
Enligt en ytterligare utforingsform är kabeln forbunden med en pa vridaxeln anordnad havarm. Rorelsen och kraften Than den f6rsta manoverspaken kan armed overforas till vridaxeln for att paverka sparrmekanismen och fastelementet i syfte att snabbt och effektivt bringa ryggstodet till det andra, nerfallda laget. 3 Enligt en ytterligare utforingsfornn är en andra manoverspak anordnad pa vridaxeln. Darmed kan sparrmekanismen och fastelementet manovreras genom att paverka den pa vridaxeln anordnade andra rnanoverspaken. FOretradesvis är vridaxeln och darmed den andra manoverspaken sa placerad vid fordonsstolen att en person som befinner sig bakom fordonsstolen och ryggstOdet kan paverka den andra manoverspaken f6r att nerfalla ryggstodet. Darmed kan den i fordonsstolen sittande personen eller andra personer i fordonet snabbt och enkelt kan evakueras ur fordonet utan att fordonsstolen utgor ett hinder. According to a further embodiment, the cable is connected to a sea arm arranged on the rotary shaft. The movement and force Than the first maneuvering lever can be armed transferred to the pivot shaft to actuate the ratchet mechanism and the fastening element in order to quickly and efficiently bring the backrest to the second, fallen team. According to a further embodiment, a second control lever is arranged on the rotary shaft. This allows the locking mechanism and the fastening element to be maneuvered by actuating the second transverse lever arranged on the rotary shaft. Preferably, the pivot shaft and thus the second control lever is positioned at the vehicle seat so that a person behind the vehicle seat and the backrest can actuate the second control lever to fall down the backrest. Thus, the person sitting in the vehicle seat or other persons in the vehicle can be quickly and easily evacuated from the vehicle without the vehicle seat constituting an obstacle.

Baspartiet 2 är uppbyggt av ett ramverk 6, som är fOrbundet med fordonet 4. Pa ramverket 6 är en sits 12 anordnad, vilken är ledbart forbunden med baspartiet 2. Sitsen 12 innefattar en eftergivlig baryta 14, som är anordnad vid och uppbares av en atminstone delvis kring barytan 14 omgivande ram 16. Fordonsstolen 1 uppvisar ocksa ett ryggst6d 22, som är anordnat vid ram- 4 verket 6. Ryggstodet 22 ar foretradesvis utfornnat av ett eftergivligt material och är uppburet av lastbarande linor 23, som är losgorbart forbundna med ramverket 6. Foretradesvis är de lastbarande linorna 23 utformade som rem mar, vilka loper kring en for respektive rem anordnad tapp 32, som är fasta vid ramverkets 6 ovre parti. De lastbarande linorna 23 är foretradesvis forbundna vid de yttre andarna av en Ovre ande av ryggstodet 22. DESCRIPTION OF EMBODIMENTS Fig. 1 shows a vehicle seat 1 according to the present invention. The vehicle seat 1 comprises a base portion 2 for attachment to a vehicle 4. The base portion 2 is built up of a framework 6, which is connected to the vehicle 4. On the frame 6 a seat 12 is arranged, which is hingedly connected to the base portion 2. The seat 12 comprises a resilient bar surface 14, which is arranged at and supported by a frame 16 surrounding at least partially around the bar surface 14. The vehicle seat 1 also has a backrest 22, which is arranged at the frame 4. supported by load-bearing ropes 23, which are releasably connected to the frame 6. Preferably, the load-bearing ropes 23 are designed as straps, which run around a pin 32 arranged for each strap, which are fixed to the upper part of the frame 6. The load-bearing ropes 23 are preferably connected to the outer spirits by an upper spirit of the backrest 22.
Ett sakerhetsbalte 26 är fast vid och stacker sig mellan sitsens 12 sidor. Sakerhetsbaltet 26 är ocksa fOrbundet vid sitsens 12 framkant samt innefattar ett axelparti 28, som är f6rbundet med insidan av ett tak 30 i fordonet 4. Fordonet 4 kan exempelvis vara ett terrangfordon eller ett stridsfordon. Med hjalp av sakerhetsbaltet 26 kvarhalls en i fordonsstolen 1 sittande person om fordonet 4 utsatts for kraftiga stotar pa grund av ojarnnt markunderlag eller om fordonet 4 \falter. Dessutom kan fordonet 4 utsattas f6r mycket kraftiga st6tar av en sprangladdning, sasonn en mina, som detonerar un- der fordonet 4. I fig. 1 visas ocksa pa ramverket 4 anordnad justerutrustning 34 for att justera och anpassa fordonsstolen 1 for den i fordonsstolen 1 sittande personen. Pa ramverkets 6 ovre parti är ocksa en forsta manoverspak 36 anordnad, vars funktion skall beskrivas nedan. A seat belt 26 is attached to and extends between the sides of the seat 12. The safety bolt 26 is also connected to the front edge of the seat 12 and comprises a shaft portion 28, which is connected to the inside of a roof 30 in the vehicle 4. The vehicle 4 may be, for example, an off-road vehicle or a combat vehicle. With the aid of the safety belt 26, a person sitting in the vehicle seat 1 is retained if the vehicle 4 has been subjected to severe impacts due to uneven ground or if the vehicle 4 falls. In addition, the vehicle 4 can be subjected to very strong shocks by an explosive charge, such as a mine, which detonates under the vehicle 4. Fig. 1 also shows adjusting equipment 34 arranged on the frame 4 for adjusting and adapting the vehicle seat 1 to the one sitting in the vehicle seat 1. persons. A first control lever 36 is also arranged on the upper part of the framework 6, the function of which will be described below.
Fig. 2 visar fordonsstolen 1 i en perspektivvy bakifran. Ramverket 6 med den tillho- rande justerutrustningen 34 for fordonsstolen 1 har i fig. 2 avlagsnats i fortydligande syfte. Av sannma anledning har ocksa sakerhetsbaltet 26 avlagsnats. Det framgar hur ryggst6det 22 uppbares av de lastbarande linorna 23, som stracker sig i en riktning uppat fran ryggstodets 22 Ovre ande fOr att darefter vanda nedat bakom ryggstOdet 22 efter att passerat den for respektive lastbarande lina 23 anordnade tappen 32, som är fast vid ramverkets 6 Ovre parti, vilket visas i fig. 1. Fig. 2 shows the vehicle seat 1 in a perspective view from behind. The frame 6 with the associated adjusting equipment 34 for the vehicle seat 1 has been removed in Fig. 2 for clarification purposes. For real reasons, the safety belt 26 has also been removed. It can be seen how the backrest 22 is supported by the load-bearing ropes 23, which extend in an upward direction from the upper end of the backrest 22 and then wander downwards behind the backrest 22 after passing the pin 32 provided for each load-bearing rope 23, which is fixed to the frame. 6 Upper portion, as shown in Fig. 1.
Om fordonet 4 maste evakueras och den i fordonsstolen 1 sittande personen inte sjalv formar att lamna fordonet 4 är fordonsstolen 1 sa utformad att personen snabbt och enkelt kan hjalpas ut ur fordonet 4 utan att fordonsstolen 1 utgor ett hinder. Det- samma galler om personen sjalv eller medpassagerare forsoker lamna fordonet 4, sa kommer fordonsstolen 1 inte utgora ett hinder for utrymningen. Av den anledningen är de hos ryggstodet 22 lastbarande linorna 23 f6rbundna med en manovrerbar fästanordning 38, som i ett forsta lage är anordnad att fasthalla andarna hos de lastba- rande linorna 23 for att liana ryggstodet 22 uppfallt. I ett andra lage är den manovrerbara fastanordningen 38 anordnad att frigara de lastbarande linorna 23 for att falla ner ryggst6det 22. Nar fastanordningen 38 frig6r de lastbarande linornas 23 andar kommer tyngden fra'n den i fordonsstolen 1 sittande personen att trycka ryggstodet 22 nedat, vilket medfor att de lastbarande linorna 23 kommer att lopa kring respek- tive tapp 32. De lastbarande linorna 23 kommer saledes inte att halla ryggstodet 22 uppfallt nar den manovrerbara fastanordningen 38 styrs till det andra laget och frigar de lastbarande linorna 23. For det fall ryggst6det 22 besthr av ett mjukt och/eller eftergivligt material kommer ryggstOdet 22 att kollapsa nar de lastbarande linorna 23 frig6rs Than fastanordningen 38. Darmed kommer den i fordonsstolen 1 sittande personen att falla bakat, vilket medger utrymning bakat fran fordonsstolen 1. Det är ocksa mojligt att utfora ryggstodet 22 i ett styvt material, varvid ryggstodet kommer att tippas bakat och behalla sin ursprungliga form nar den manovrerbara fastanordningen 38 styrs till det andra laget och frig& de lastbarande linorna 23. Aven sitsens 12 horisontella lage kan paverkas nar de lastbarande linorna 23 frigars fran fastan- ordningen 38. Genom att anordna sitsen 12 ledad eller farskjutbar vid ramverket 6 kan sitsen sjunka nedat i fordonet 4 nar de lastbarande linorna 23 frigars fran fastanordningen 38, vilket nnedfor att utrynnnnet for att evakuera och utrymma fordonet 4 ytterligare akar. Detta majliggars genom att forbinda ryggstadets 22 nedre ande med sitsen 12, vilket medfar att nar de lastbarande linorna 23 frig6rs fran fastanordningen 38 halls ryggstodet 22 inte lagre uppe av de lastbarande linorna 23, vilket i sin tur medfar att sitsen 12 inte langre halls uppe av ryggstOdet 22. If the vehicle 4 must be evacuated and the person sitting in the vehicle seat 1 does not form to leave the vehicle 4 himself, the vehicle seat 1 is designed so that the person can be quickly and easily helped out of the vehicle 4 without the vehicle seat 1 constituting an obstacle. The same applies if the person himself or fellow passengers try to leave the vehicle 4, then the vehicle seat 1 will not constitute an obstacle to the evacuation. For this reason, the ropes 23 carrying the backrest 22 are connected to a manoeuvrable fastening device 38, which in a first layer is arranged to hold the spirits of the load-bearing ropes 23 in order to line the backrest 22 strikingly. In a second layer, the maneuverable fastener 38 is arranged to release the load-bearing ropes 23 to fall down the backrest 22. When the fastener 38 releases the spirits of the load-bearing ropes 23, the weight of the person sitting in the vehicle seat 1 will push the backrest 22 downwards, which so that the load-bearing ropes 23 will run around respective pins 32. The load-bearing ropes 23 will thus not hold the backrest 22 incident when the manoeuvrable fastening device 38 is guided to the second layer and releases the load-bearing ropes 23. In that case the backrest 22 consists of a soft and / or resilient material, the backrest 22 will collapse when the load-bearing ropes 23 are released. the backrest 22 in a rigid material, the backrest being tilted back and retaining its original in the form of the maneuverable fastening device 38 being guided to the second layer and releasing the load-bearing ropes 23. The horizontal position of the seat 12 can also be affected when the loading-bearing ropes 23 are released from the fastening device 38. the seat sinks downwards in the vehicle 4 when the load-bearing ropes 23 are released from the fixed device 38, which means that it has to be emptied to evacuate and evacuate the vehicle 4 further fields. This is accomplished by connecting the lower end of the backrest 22 to the seat 12, which means that when the load-bearing ropes 23 are released from the fixed device 38, the backrest 22 is not held lower by the load-bearing ropes 23, which in turn means that the seat 12 is no longer held by the backrest 22.
Fig. 3 visar en perspektivvy bakifran med ryggstOdet 22 nerfallt. Ramverket 6 med den tillhorande justerutrustningen 34 for fordonsstolen 1 visas i figuren, och det framgar att de lastbarande linorna 23 frigjorts, vilket medfar att ryggstOdet 22 nerfallts och hamnat bakom ramverket 6. Nar ryggstodet 22 är nerfallt kommer en i fordonsstolen 1 sittande person snabbt och enkelt kunna hjalpas ut ur fordonet 4 utan att fordonsstolen 1 utgor ett hinder. Samtidigit kommer fordonsstolen 1 inte att utgora ett hinder om medpassagerare forsaker lamna fordonet 4 vid utrymningen. Ryggstadet 22 far en mycket kompakt form i det nerfallda laget nar det anligger mot golvet i fordonet 1 och är armed inte i vagen far personal som skall ta sig ur fordonet 1 vid evakuering. Fordonsstolen 1 kan exempelvis utgoras av en forarstol, som är avsedd far fordonets 4 forare. Far det fall fordonet 4 är ett stridsfordon kan den enda majliga 6 utrynnningsvagen ur fordonet 4 vara bakat och forbi det utrynnnne som upptages av ryggstodet 22 nar det är uppfallt. Fig. 3 shows a perspective view from behind with the backrest 22 lowered. The frame 6 with the associated adjusting equipment 34 for the vehicle seat 1 is shown in the figure, and it appears that the load-bearing ropes 23 have been released, which means that the backrest 22 has fallen down and ended up behind the frame 6. When the backrest 22 is dropped, a person sitting in the vehicle seat 1 quickly can easily be helped out of the vehicle 4 without the vehicle seat 1 constituting an obstacle. At the same time, the vehicle seat 1 will not constitute an obstacle if fellow passengers attempt to leave the vehicle 4 during the evacuation. The backrest 22 takes on a very compact shape in the fallen team when it rests against the floor of the vehicle 1 and is not armed in the carriage by personnel who are to get out of the vehicle 1 during evacuation. The vehicle seat 1 can, for example, consist of a driver's seat, which is intended for the driver of the vehicle 4. In case the vehicle 4 is a combat vehicle, the only male 6 carriage out of the vehicle 4 can be baked and past the carcass taken up by the backrest 22 when it is noticed.

Figures 4 and 5 show perspective views of the maneuverable fixed device 38 for the vehicle seat 1. The manoeuvrable fixed device 38 is designed to be maneuvered by both the person sitting in the vehicle seat 1 and by other persons in the vehicle 4 and comprises a first operating vehicle 40, for bringing the fixed device 38 to the second layer and release the load-bearing ropes 23. The first actuator 40 comprises the first control lever 36, shown in Fig. 1. The first actuator also comprises a lever arm 42 of the fixed device 38 and a cable 44 or wire, which is arranged between the first control lever 36 and the lever 42. The first control lever 36 is preferably placed in a suitable place in relation to the vehicle seat 1, whereby movement and force from the first control lever 36 are transmitted via the cable 44 to the lever 42 of the fixed device 38. According to Figs. In the embodiment shown, the first control lever 36 is arranged at the upper part of the framework 6, which is that the first control lever 36 is accessible to the person sitting in the vehicle seat 1. However, the maneuverable fixed device 38 can be maneuvered both by the person sitting in the vehicle seat 1 and by other persons in the vehicle 4.
Den manovrerbara fastanordningen 38 innefattar ett for vane lastbarande lina 23 anordnat fastelement 46, som effektivt forbinder de lastbarande linorna 23 med fastanordningen 38. Fastanordningen 38 innefattar aven en for varje fastelement 46 anordnad sparrmekanism 48, som i det fOrsta laget sparrar fastelementet 46 och i det andra laget frig6r fastelementet 46. I fig. 4 visas sparrmekanismen 48 i det fOrsta la- get och i fig. 5 visas sparrmekanismen 48 i det andra laget. Nar sparrmekanismen 48 sparrar fastelementet 46 kommer fastelement 46 effektivt f6rbinda de lastbarande linorna 23 med fastanordningen 38. Nar sparrmekanismen 48 frig& fastelementet 46 kommer de lastbarande linorna 23 att snabbt och effektivt frig6ras Than fastanord- ningen, sa att ryggstodet 22 kan neriallas. Fastanordningen 38 innefattar en vridaxel pa vilken sparrmekanismerna 48 ar anordnade. Genom att anordna sparrnnekanismerna 48 pa vridaxeln 50 kan fastanordningen 38 utforas kompakt, vilket gor fastanordningen 38 mindre utrymmeskravande. Havarmen 42 är anordnad pa vridaxeln 50. Genom att overfora rorelse och kraft fran den fOrsta manoverspaken 36 via ka- 7 beln 44 till havarnnen 42 hos fastanordningen 38 astadkonnnnes en vridrorelse hos vridaxeln 50, som darmed vrider sparrmekanismerna 48 till det i fig. 5 andra laget, sa att fastelementen 46 svangs undan av kraften Than de lastbarande linorna 23, och sa att de lastbarande linorna 23 frigors tan fastanordningen 38, vilket leder till att rygg- stodet 22 nerfalls. Foretradesvis är ett fjaderelement 52 anordnat vid vridaxeln 50 i syfte att f6ra fastanordningen 38 och darmed vridaxeln 50 till det forsta laget. Nar rOrelse och kraft fran den fOrsta manOverspaken 36 OverfOrs via kabeln 44 till havarmen 42 overvinns fjaderkraften hos fjaderelementet 52 sa att vridrorelsen hos vridaxeln 50 astadkommes. The maneuverable fastening device 38 comprises a fastening element 46 arranged as usual for load-bearing line 23, which effectively connects the load-bearing ropes 23 to the fastening device 38. The fastening device 38 also comprises a locking mechanism 48 arranged for each fastening element 46, which first locks the fastening element 46 and in the the second layer releases the fastening element 46. Fig. 4 shows the ratchet mechanism 48 in the first layer and Fig. 5 shows the ratchet mechanism 48 in the second layer. When the ratchet mechanism 48 locks the fastener 46, fastener 46 will effectively connect the load-bearing ropes 23 to the fastener 38. When the ratchet 48 releases the fastener 46, the load-bearing ropes 23 will be quickly and efficiently released from the fastener so that the backrest 22 can be lowered. The fastening device 38 comprises a pivot shaft on which the locking mechanisms 48 are arranged. By arranging the locking mechanisms 48 on the rotary shaft 50, the fastening device 38 can be made compact, which makes the fastening device 38 less space-consuming. The sea arm 42 is arranged on the rotary shaft 50. By transmitting movement and force from the first control lever 36 via the cable 44 to the port arm 42 of the fixed device 38, a rotational movement of the rotary shaft 50 is achieved, which thereby rotates the ratchet mechanisms 48 to the second in Fig. 5. said that the fastening elements 46 are pivoted away by the force than the load-bearing ropes 23, and said that the load-bearing ropes 23 are released tan the fastening device 38, which leads to the backrest 22 falling down. Preferably, a spring element 52 is arranged at the pivot shaft 50 in order to move the fixed device 38 and thus the pivot shaft 50 to the first layer. When movement and force from the first control lever 36 are transmitted via the cable 44 to the sea arm 42, the spring force of the spring element 52 is overcome so that the rotational movement of the rotary shaft 50 is achieved.
Sparrmekanismen 48 samverkar med respektive fastelement 46 medelst en hake 54 eller krok, som i det forsta laget anligger mot och forhindrar fastelementen 46 att svangas undan av kraften Than de lastbarande linorna 23. Nar vridaxeln 50 och darmed sparrmekanismerna 48 vrids till det for fastanordningen 38 andra laget konnmer haken 54 eller kroken hos respektive sparrmekanism att forlora kontakten med faste- lementen 46, vilket medfor att fastelementen 46 svangs undan av kraften Than de lastbarande linorna 23. The locking mechanism 48 cooperates with the respective fastening element 46 by means of a hook 54 or hook, which in the first layer abuts against and prevents the fastening elements 46 from being swung away by the force Than the load-bearing lines 23. When the pivot shaft 50 and thus the locking mechanisms 48 are rotated to the team causes the hook 54 or the hook of the respective ratchet mechanism to lose contact with the fastening elements 46, which means that the fastening elements 46 are pivoted away by the force Than the load-bearing ropes 23.
Ett andra manoverdon 56, som innefattar en andra manoverspak 58, är anordnat pa respektive sparrmekanism 48. Med den andra manoverspaken 58 kan respektive sparrmekanism 48 manovreras genom att med en kraft paverka den pa vridaxeln 50 anordnade andra manoverspaken 58, sa att ett vridmoment kring vridaxeln 50 alstras. Nar vridmomentet overvinner fjaderkraften fran fjaderelementet 52 astadkommes en vridrOrelse hos vridaxeln 50, som vrider sparrmekanismerna 48 till det i fig. andra laget, sa att fastelementen 46 svangs undan av kraften fran de lastbarande linorna 23, och sa att de lastbarande linorna 23 frigOrs fran fastanordningen 38, vilket leder till att ryggstodet 22 nerfalls. Foretradesvis är vridaxeln 50 och darmed den andra manoverspaken 56 sa placerad vid fordonsstolen 1 att en person som befinner sig bakom fordonsstolen 1 och ryggstodet 22 kan paverka den andra manoverspa- ken 58. Ryggstodet 22 kan darmed nerfallas, sa att den i fordonsstolen 1 sittande personen eller andra personer i fordonet 4 snabbt och enkelt kan evakueras ur fordonet 4 utan att fordonsstolen 1 utgor ett hinder. Beskrivna utforingsformer ovan kan kombineras med varandra och anvandas samtidigt pa en och samma fordonsstol 1. 8 A second actuator 56, which comprises a second control lever 58, is arranged on the respective ratchet mechanism 48. With the second control lever 58, the respective ratchet mechanism 48 can be operated by forcibly actuating the second operating lever 58 arranged on the rotary shaft 50, so that a torque around the rotary shaft 50 alstras. When the torque overcomes the spring force from the spring element 52, a rotational movement of the rotary shaft 50 is effected, which rotates the ratchet mechanisms 48 to that of the second layer in Fig. 2, so that the fasteners 46 are pivoted away from the load 38, which results in the backrest 22 falling down. Preferably, the pivot shaft 50 and thus the second control lever 56 is positioned at the vehicle seat 1 so that a person behind the vehicle seat 1 and the backrest 22 can actuate the second control lever 58. The backrest 22 can thus be lowered, so that the person sitting in the vehicle seat 1 or other persons in the vehicle 4 can be quickly and easily evacuated from the vehicle 4 without the vehicle seat 1 constituting an obstacle. The embodiments described above can be combined with each other and used simultaneously on one and the same vehicle seat 1. 8
