Description

10 15 20 25 30 35 J* CJ \ C: J (JJ CI' L, l N Vid en kollision uppblåses SRS-enhetens gassäck hastigt. var- efter den töms på gas under energiupptagning, när den trycks ihop under den âkandes tyngd och gasen i säcken pressas ut genom hål i säcken. Vid högre krockhastigheter kan det i slut- skedet av kollisionsförloppet inträffa att den åkande trots närvaro av gassäcken slår i ratten och i beroende av hur stor resterande rörelseenergi den åkande har kan rattringen samt SRS-enheten orsaka skador. 10 15 20 25 30 35 J * CJ \ C: J (JJ CI ' L, l N In the event of a collision, the SRS unit's gas bag inflates rapidly. where- after it is emptied of gas during energy absorption, when pressed together under the weight of the patient and the gas in the bag is squeezed out through holes in the bag. At higher crash speeds, it may eventually stage of the collision process occur that the occupant despite presence of the gas bag strikes the steering wheel and depending on the size residual kinetic energy the rider has can the steering wheel as well The SRS device is causing damage.

Syftet med föreliggande uppfinning är att åstadkomma en for- donsratt av i inledningen angivet slag, genom vilken det är möjligt att reducera skadeverkningarna i samband med en kolli- sion, vid vilken den energiabsorberande säcken inte förmår absorbera tillräckligt medrenergi för att förhindra rattislag.The object of the present invention is to provide a steering wheel of the type specified in the introduction, by which it is possible to reduce the adverse effects of a collision at which the energy-absorbing bag is not capable of absorb enough co-energy to prevent steering stroke.

Detta uppnås enligt uppfinningen genom att gaskuddeanordningen är fast förbunden med rattcentrum via en från rattcentrum upp- skjutande, från rattkransen och dess förbindelseelement med rattcentrum skild och så formad bärare, att bäraren vid viss tryckbelastning av gaskuddeanordningen kan deformeras för att medge av förskjutning av rattkransen oberoende förskjutning av gaskuddeanordningen mot rattcentrum.This is achieved according to the invention by the gas cushion device is permanently connected to the steering wheel center via a steering wheel sliding, from the steering wheel and its connecting elements with steering wheel center separated and so shaped carrier, that the carrier at certain pressure load of the gas cushion device can be deformed to allow of displacement of the steering wheel independent displacement of the gas cushion device towards the steering wheel center.

Genom utförandet enligt uppfinningen är det möjligt att inordna en gaskuddeanordning i den kedja av komponenter i en styrinrättning, i vilken genom bestämd dimensionering och for- mgivning av komponenterna ett avsiktligt deformationsförlopp med åtföljande styrd energiupptagning kan uppnås.By the embodiment according to the invention it is possible to arrange a gas cushion device in the chain of components in a control device, in which by certain dimensioning and giving the components a deliberate deformation process with concomitant controlled energy uptake can be achieved.

Uppfinningen beskrives närmare under hänvisning till på bifo- gade ritningar visade utföringsexempel. där fig. 1 visar en perspektivisk röntgenvy av en schematisk framställd fordons- ratt med en ännu icke monterad gaskuddeanordning, fig. 2 en vy motsvarande fig. 1 med gaskuddeanordningen monterad och fig. 3 en vy motsvarande fig. 2 efter förarislag i samband med kolli- síon.The invention is described in more detail with reference to the appended drawings show exemplary embodiments. where Fig. 1 shows a perspective X-ray view of a schematically represented vehicle steering wheel with a gas cushion device not yet mounted, Fig. 2 a view corresponding to Fig. 1 with the gas cushion device mounted and Fig. 3 a view corresponding to Fig. 2 by driver type in connection with the collision síon.

Den i figurerna visade ratten 1 har en rattkrans 2. bestående av en av ett folieöverdraget skumplasthölje 3 omgiven stålring 10 15 20 25 30 35 3 463 šüš 4. Ringen 4 är via ekrar 5 förbunden med ett rattcentrum i form av ett nav 6. vilket är monterad på en rattaxel 7. Ekrar- na 5 är på känt sätt dimensionerade och formade för att defor- meras vid viss belastning av rattkransen 2 och därmed absor- bera energi och innefattar för detta ändamål metallband 8, vilka är bockade vid 9 för att kunna veckas vid belastning.The steering wheel 1 shown in the figures has a steering wheel ring 2 consisting of of a steel ring 3 surrounded by a foil-coated foam plastic casing 10 15 20 25 30 35 3 463 šüš 4. The ring 4 is connected via spokes 5 to a steering wheel center in in the form of a hub 6. which is mounted on a steering axle 7. 5 are dimensioned and shaped in a known manner in order to under certain load on the steering wheel ring 2 and thus absorbed carry energy and for this purpose comprises metal strips 8, which are bent at 9 to be able to be folded under load.

Ekrarna 5 är liksom kransen 2 omgiven av det folieöverdragna skumplasthöljet 3.The spokes 5 are like the wreath 2 surrounded by the foil coated the foam cover 3.

En generellt med 10 betecknad gaskuddeanordníng, vilken kan vara av den i och för sig kända typ. som går under beteck- ningen SRS-enhet, är monterad centralt i ratten. I enlighet med uppfinningen är enheten 10 förbunden direkt med navet 6 under förmedling av fyra i huvudsak i Z-form bockade metall- band ll. vilka är förbundna med varandra parvis medelst ett par metallremsor 12, som i sin tur bildar fästen för enheten 10.A gas cushion device generally designated 10, which can be of the type known per se. which goes under the designation sRS unit, is mounted centrally in the steering wheel. According with the invention, the unit 10 is connected directly to the hub 6 while conveying four mainly Z-shaped bent metal band ll. which are connected to each other in pairs by means of one pair of metal strips 12, which in turn form brackets for the unit 10.

Såsom framgår av figurerna uppnås med det beskrivna arrange- manget en gaskuddeinstallation. som vad beträffar sin infäst- ning är helt frikopplad från rattkransen 2 och rattekrarna 5.As can be seen from the figures, the described arrangement is achieved many a gas cushion installation. as regards its attachment is completely disengaged from the steering wheel ring 2 and the steering wheel hubs 5.

Detta betyder att förloppet vid en kollision. som leder till förarislag i ratten, resulterar i en kontrollerad deformation med åtföljande energiupptagning oavsett om föraren först slår i rattkransen 2 eller gaskuddeanordningen 10. I fig. 3 illust- reras formen hos rattekrarnas och gaskuddeanordningens metall- band 8 resp. ll efter förarislag i ratten. Figuren visar slut- resultatet efter förloppet vid en kollision, som resulterat i att både rattkransen 2 och gaskuddeanordningen 10 belastats så kraftigt, att rattekrarnas 5 metallband 8 och enhetens 10 metallband 11 deformerats. Oberoende av om föraren träffar rattkransen 2 eller gaskuddeanordningen 10 först erhålles ett kontrollerat förlopp. vid vilket banden 8 och ll fungerar som energiupptagare både i serie och parallellt med varandra.This means that the course of a collision. which leads to driver impact in the steering wheel, resulting in a controlled deformation with accompanying energy consumption regardless of whether the driver strikes first in the steering wheel ring 2 or the gas cushion device 10. In Fig. 3 illustrated the shape of the metal of the steering wheel and gas cushion device band 8 resp. ll after driving in the steering wheel. The figure shows the final the result after the course of a collision, which resulted in that both the steering wheel ring 2 and the gas cushion device 10 are so loaded strongly, that the metal strip 8 of the steering wheel 5 and the unit 10 of the unit 10 metal strip 11 deformed. Regardless of whether the driver hits the steering wheel ring 2 or the gas cushion device 10 is first obtained one controlled course. at which bands 8 and 11 function as energy absorbers both in series and in parallel with each other.

Inom ramen för uppfinningen kan även andra deformerbara organ än bockade metallband utnyttjas för fixering av gaskuddeanord- ningen vid rattcentrum. Exempelvis kan en metallbälg anordnas mellan rattcentrum och gaskuddeanordningen.Other deformable members can also be used within the scope of the invention than bent metal strips are used for fixing gas cushion devices. at the steering wheel center. For example, a metal bellows can be provided between the steering wheel center and the gas cushion device.
