Description
10 15 20 25 30 35 463 553, 2 rattaxel och leder, som tillsammans givit en avsiktlig, styrd kollaps hos styrsystemet med åtföljande styrd energiupptagning vid kollision. vid en kollision uppblåses SRS-enhetens gassäck hastigt, var- efter den töms på gas under energiupptagning. när den trycks ihop under den åkandes 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 gassäcker 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 35 463 553, 2 steering axle and joints, which together have given a deliberate, steered collapse of the control system with concomitant controlled energy uptake in the event of a collision. in the event of a collision, the gas bag of the SRS unit inflates rapidly, after it is emptied of gas during energy absorption. when pressed together under the weight of the rider 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 gas bags 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.
Det är även känt exempelvis genom US-A-3 600 003 att samordna en teleskopisk rattaxel och ett hoptryckbart rattrör med en gaskuddeanordning, vilken har en utlösningsmekanism, som vid uppblåsning av gaskudden samtidigt medverkar till att ratt- röret kollapsar.It is also known, for example, from US-A-3,600,003 to coordinate a telescopic steering axle and a compressible steering tube with a gas cushion device, which has a release mechanism, as in inflation of the gas cushion at the same time contributes to the pipe collapses.
Syftet med föreliggande uppfinning är att åstadkomma en styr- inrättning av i inledningen angivet slag. vid vilken i stället det hoptryckbara rattröret medverkar till energiabsorbtion i serie med gaskuddeanordningen.The object of the present invention is to provide a control establishment of the kind specified in the introduction. at which instead the compressible steering tube contributes to energy absorption in series with the gas cushion device.
Detta uppnås enligt uppfinningen genom att gaskuddeanordningen är inrättad att utlösas vid kollision för att absorbera energi i ett första steg oberoende av lageranordningen och att denna är anordnad att deformeras vid viss belastning av ratten och/eller gaskuddeanordningen för att absorbera energi i ett ytterligare steg efter det första steget.This is achieved according to the invention by the gas cushion device is designed to be triggered in the event of a collision to absorb energy in a first step independent of the bearing device and that this is arranged to be deformed at a certain load on the steering wheel and / or the gas cushion device for absorbing energy in one additional steps after the first step.
Utförandet enligt uppfinningen innebär att gaskuddeanordningen inte utnyttjas som ett alternativ till i och för sig kända passiva säkerhetsarrangemang i en styrinrättning utan istället inordnas i den kedja av komponenter i styrínrättníngen. i vil- ken genom bestämd dimensionering och formgivning av komponen- terna ett styrt deformationsförlopp i flera steg kan uppnås. 10 15 20 25 30 35 3 465 553 Uppfinningen beskrives närmare under hänvisning till på bifo- gade ritningar visade utföringsexempel, där fig. 1 visar en perspektivisk röntgenvy av en schematiskt framställd fordonsratt. fíg. 2 ett längdsnitt genom en schematiskt framställd styrin- rättning innefattande ratten i fig. 1 samt fig. 3, en vy av styrinrättningen i fig. 2 i deformerat till- stånd efter förarislag.The embodiment according to the invention means that the gas cushion device not be used as an alternative to per se known passive safety arrangements in a control device but instead arranged in that chain of components of the steering gear. in vil- through specific dimensioning and design of the components a controlled deformation process in several stages can be achieved. 10 15 20 25 30 35 3 465 553 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 schematic manufactured vehicle steering wheel. fig. 2 is a longitudinal section through a schematically represented guide correction including the steering wheel in Fig. 1 and Fig. 3, a view of the control device of Fig. 2 in a deformed stand after driver's license.
Den i figurerna visade ratten l har en rattkrans 2, bestående av en av ett folieöverdraget skumplasthölje 3 omgiven stålring 4. Ringen 4 är via ekrar 5 förbunden med ett rattcentrum i form av ett nav 6, vilket är monterad på en rattaxel 7. Ek- rarna 5 är på känt sätt dimensionerade och formade för att de- formeras vid viss belastning av rattkransen 2 och innefattar för detta ändamål metallband 8, vilka är bockade vid 9 för att kunna veckas vid belastning. Ekrarna 5 är liksom kransen 2 om- given av det folieöverdragna skumplasthöljet 3.The steering wheel 1 shown in the figures has a steering wheel ring 2, consisting of a steel ring 3 surrounded by a foil-coated foam plastic casing 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 shaft 7. 5 are dimensioned and shaped in a known manner in order to formed at a certain load on the steering wheel ring 2 and includes for this purpose metal strips 8, which are bent at 9 to can be folded under load. The spokes 5, like the wreath 2, are given by the foil-coated foam cover 3.
En generellt med 10 betecknad gaskuddeanordning. vilken kan vara av den i och för sig kända typ. som går under beteck- ningen SRS-enhet. är monterad centralt i ratten. Enheten 10 är förbunden direkt med navet 6 under förmedling av fyra i huvud- sak i Z-form bockade metallband 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 device. is mounted centrally in the steering wheel. Unit 10 is directly connected to the hub 6 while transmitting four in the main thing in Z-shape bent metal strip ll. which are associated with each other in pairs by means of a pair of metal strips 12. which in turn forms brackets for the device 10..
Rattaxeln 7 har en rörformig överdel 7a med invändiga splines och en nederdel 7b med utvändiga splines. som inskjuter i överdelen 7a. Delarna 7a och 7b är således axiellt förskjut- bart men ovridbart förbundna med varandra. Rattaxeln 7 är lag- rad i ett övre och ett nedre lager 20 resp. 21 i ett rörfor- migt lagerhus 22, som har vid 23 och 24 schematiskt antydda fästen i fordonet. Lagerhuset 22 består av metall och har ett veckat parti 25 avsett att ge en kontrollerad komprimering av röret vid belastning i samband med förarislag vid kollision.The steering shaft 7 has a tubular upper part 7a with internal splines and a lower part 7b with external splines. which inserts in upper part 7a. The parts 7a and 7b are thus axially displaced. bare but inextricably linked. The steering shaft 7 is row in an upper and a lower layer 20 resp. 21 in a tubular migt bearing housing 22, which has at 23 and 24 schematically indicated mounts in the vehicle. The bearing housing 22 consists of metal and has one pleated portion 25 intended to provide a controlled compression of the pipe under load in connection with the driver's impact in the event of a collision.
Det övre fästet 23 är dimensionerat att tåla lägre belastning än det nedre fästet 24. vid viss belastning på ratten brister 463 555 4 10 fästet 23, varefter ratten kan förskjutas framåt under kompri- mering av det veckade partiet 25 och inskjutning av axeldelen 7b i delen 7a. vid en kollosion som utlöser gaskuddeanordningen uppfångas föraren först av gaskudden. Om kollisionen är så kraftig, att föraren trots gaskudden i slutskedet träffar ratten med stor kraft, erhålles energiupptagning i ett andra steg när banden 8 och 11 deformeras vid belastning av rattkransen 2 och gas- kuddeanordningen 10. Energiupptagning i ett tredje steg er- hålles, när det övre rörfästet 23 brister och röret 22 kompri- meras, såsom illustreras i fig. 3.The upper bracket 23 is dimensioned to withstand lower loads than the lower bracket 24. at some load on the steering wheel breaks 463 555 4 10 bracket 23, after which the steering wheel can be moved forward during compression. insertion of the pleated portion 25 and insertion of the shaft portion 7b in section 7a. in a collision that triggers the gas cushion device is captured the driver first of the gas cushion. If the collision is so severe, that the driver, despite the gas cushion in the final stage, hits the steering wheel with a big power, energy uptake is obtained in a second step when the belts 8 and 11 are deformed when the steering wheel ring 2 is loaded and the gas pillow device 10. Energy absorption in a third step when the upper pipe bracket 23 breaks and the pipe 22 compresses as illustrated in Fig. 3.
