Abstract

A seat in a vehicle has a squab(1) which is fastened to the vehicle floor. A back-rest(9) is mounted on the squab so that when the vehicle is hit from the back, the lower part of the seat-back moves back relative to the squab and head-rest on the upper part. Energy is absorbed by an energy absorber. The head of the vehicle occupant is brought into contact with the head-rest. The entire seat-back may then move backwards, for example by pivoting about an axis defined by a recliner(3).

Description

in »ml 1:1 :zlzza in' v 512 722 2 huvudet av stolens nackstöd ( eller av ryggstödet om personen är kort). I och med att ryggstödets nedre del ( 7 ) utsättes för en plötslig och kraftig belastning utlöses en speciell mekanism så att ryggstödet kommer att i en integrerad rörelse föras bakåt och uppåt. Dessa lägesändringar är i figur 2 markerade med kraftpilar 8 och 9. Ryggstödets övre del 10 kommer att föras framåt relativt fordonets färdriktning och som i figur 2 markeras av kraftpilen 11. in »ml 1: 1: zlzza in 'v 512 722 2 the head of the headrest of the chair (or of the backrest if the person is short). As the lower part (7) of the backrest is exposed to a sudden and heavy load, a special mechanism is triggered so that the backrest will be moved backwards and upwards in an integrated movement. These position changes are in 2gur 2 marked with power arrows 8 and 9. The upper part 10 of the backrest will be moved forward relative to the direction of travel of the vehicle and which in figur 2 is marked by the power arrow 11.

Att ryggstödets övre del föres framåt är av utomodemtligt stor betydelse emedan detta betyder att huvudet fångas upp av det mötande nackstödet 12. Vid beskriven lägesändring erhålles en förändring av ryggstödets vinkel i förhållande till den tänkta lodlinjen ( 4).The fact that the upper part of the backrest is advanced is of immeasurable importance because this means that the head is caught by the oncoming headrest 12. When the position change described is described, a change in the angle of the backrest in relation to the imaginary vertical line (4) is obtained.

Således vrids ryggstödet så att vinkeln gentemot lodlinjen förändras med minst 5°. Enligt uppfinningen kan lutningen förändras med maximalt 45°.Thus, the backrest is rotated so that the angle to the vertical changes by at least 5 °. According to the invention, the slope can be changed by a maximum of 45 °.

Vid nästa lägesändring kommer passagerarens huvud, bål och ben att i stort sett trycka an mot hela ryggstödet ( 2 ), vilket enligt uppfinningen resulterar i att hela ryggstödet fälles bakåt.At the next change of position, the passenger's head, torso and legs will largely press against the entire backrest (2), which according to the invention results in the entire backrest being folded back.

Denna lägesändring åskådliggöres av kraftpilen 13, flgur 3. På detta sätt erhålls en förhållandevis mjuk inbromsning av kroppen. Sammantaget erhålls ett ergonomiskt samspel mellan huvud ( nacke), bål och ben som resulterar i att nackskador vid påkörning bakifrån väsentligen kan reduceras och i de flesta fall elimineras vid lindrigare påkörningar.This change of position is illustrated by the force arrow 13, fl gur 3. In this way a relatively soft deceleration of the body is obtained. All in all, an ergonomic interaction is obtained between the head (neck), torso and legs, which results in that neck injuries in a rear-end collision can be significantly reduced and in most cases eliminated in milder collisions.

I enlighet med ovan gjorda beskrivning kan sammanfattningsvis sägas, att uppfinningen kännetecknas av att nedre delen av ryggstödet (7 ) i ett första moment föres bakåt och uppåt medan ryggstödets övre del ( 10 ) samtidigt föres framåt vid tryckbelastning bakifrån mot stolen. I ett andra moment tvingas ryggstödet bakåt varvid hela bålen och huvudet ligger an mot ryggstödet ( 2 ) och nackstödet ( 12 ), figur 3. Vid detta andra moment erhålles en relativt mjuk inbromsning med hjälp av till exempel en friktions-eller momentbroms som kan ingå i inställningsratten ( 3 ).In accordance with the description made above, it can be said in summary that the invention is characterized in that the lower part of the backrest (7) is moved backwards and upwards in a first step while the upper part (10) of the backrest is simultaneously moved forwards under pressure load from behind towards the chair. In a second step, the backrest is forced backwards, the entire torso and head abutting against the backrest (2) and the headrest (12), fi gur 3. In this second step, a relatively soft braking is obtained by means of, for example, a friction or torque brake which can be included in the setting knob (3).

För att åstadkomma beskrivna positioner hos stolen fordras en anordning ( 5 ) som åstadkommer beskrivna rörelseschema. I det följande skall lämnas ett exempel på en sådan mekanism, som i det följande benämnes styrskena. Det skall betonas att det kan finnas altemativ till styrskena.In order to achieve the described positions of the chair, a device (5) is required which provides the described movement diagram. The following is an example of such a mechanism, hereinafter referred to as the guide rail. It should be emphasized that there may be alternatives to the guide rail.

Styrskenan ( 5 ) utgör med sätet ( 1 ) och ryggstödet ( 2 ) en integrerad enhet. Styrskenan är försedd med minst två slitsar ( ursparingar ) 14 och 15. Den nedre slitsen ( 14 ) lutar snett uppåt i förhållande till sätet medan den övre ursparingen ( 15 ) i stort sett ligger parallellt med ryggstödet. I vardera slits finns en tapp 16 och 17 ( metallstång) som är fäst i ryggstödets sida Den övre slitsen ( 15 ) och dess tapp ( 17 ) ska placeras relativt högt upp på ryggstödet Således ska tappen ( l7 ) och slitsen ( 15 ) placeras på ett höjdläge som åtminstone utgör 40 % och företrädesvis över 50 % av ryggstödets totala höjd ( längd ).The guide rail (5) forms an integrated unit with the seat (1) and the backrest (2). The guide rail is provided with at least two slots (recesses) 14 and 15. The lower slot (14) slopes obliquely upwards relative to the seat, while the upper recess (15) is substantially parallel to the backrest. In each slot there is a pin 16 and 17 (metal bar) attached to the side of the backrest. The upper slot (15) and its pin (17) should be placed relatively high up on the backrest. Thus, the pin (l7) and the slot (15) should be placed on a height position which constitutes at least 40% and preferably over 50% of the total height (length) of the backrest.

Vid aktivering av stolens säkerhetsfunktion under det första momentet glider tappen ( 16 ) från läget 18 till läge 19. Som syns av figur 2 ger denna bana en riktning som går snett uppåt och bakåt i förhållande till tänkt färdriktning framåt. Den övre tappen ( 17 ) beskriver en tämligen lodrät bana och förflyttas från postion 20 till position 21, vilket framgår av figurer.When activating the seat's safety function during the first step, the pin (16) slides from position 18 to position 19. As can be seen from Figure 2, this path gives a direction that goes obliquely upwards and backwards in relation to the intended direction of travel forwards. The upper pin (17) describes a rather vertical path and is moved from position 20 to position 21, as shown by fi gures.

Fördelar Vid påkörningar av fordon bakifrån uppnås med installtion av föreliggande uppfinning en rad fördelar.Advantages When driving vehicles from behind, the present invention achieves a number of advantages.

En väsentlig och viktig fördel är att frekvensen av personskador reduceras och kan i de flesta fall undvikas helt och hållet. Förutom minskning av mänskligt lidande erhålls också väsentliga ekonomiska fördelar. Således kan i de flesta fall undvikas stora kostnader för både samhälle 'och individ. Vidare kan sparas stora belopp genom radikalt minskat behov av rehabiliteringsvård.Genom stolens unika konstruktion erhålls vanligtvis inga skador på själva stolen. Med smärre åtgärder kan stolen ånyo brukas.A significant and important advantage is that the frequency of injuries is reduced and can in most cases be avoided altogether. In addition to reducing human suffering, significant economic benefits are also obtained. Thus, in most cases, large costs for both society and the individual can be avoided. Furthermore, large amounts can be saved through radically reduced need for rehabilitation care. Through the chair's unique construction, no damage is usually obtained to the chair itself. With minor measures, the chair can be used again.
