Abstract
Description
Die Erfindung betrifft einen Gasgenerator mit radialen Abströmöffnungen für aufblasbare, dem Schutz der In sassen von Kraftwagen dienende Gaskissen.The invention relates to a gas generator with radial Discharge openings for inflatable, protecting the In sat gas cushions from motor vehicles.
Die Anordnung radialer Abströmöffnungen ist bei noch nicht montiertem Generator insofern von Vorteil, als bei einer Fehlauslösung des Treibsatzes praktisch keine axiale Komponente des ausströmenden Gases auftritt, so daß der Generator in diesem Falle nicht als gefähr liches Wurfstück wirken kann.The arrangement of radial outflow openings is still at non-assembled generator is advantageous in that practically none if the propellant is triggered incorrectly axial component of the outflowing gas occurs, so that the generator is not considered dangerous in this case can throw.
Beim Auslösen des eingebauten Generators ergeben sich durch eine solche Konstruktion jedoch die folgenden Nach teile.When the built-in generator is triggered by such a construction, however, the following after parts.
Die ganze Gaskisseneinheit ist im Fahrzeug üblicherweise durch eine Polsterplatte abgedeckt, die mittig verlaufende Sollbruchlinien als Aufreißkanten aufweist, die durch das sich entfaltende Gaskissen zerstört werden. Bei über wiegend radialem Gasaustritt werden diese Aufreißkanten aber nur ungenügend beaufschlagt, so daß an ungewollten Stellen der Polsterplatte unkontrollierbare Anrisse ent stehen, die u.U. bis zu einem unerwünschten Ablösen von Polsterfetzen führen können.The entire gas cushion unit is common in the vehicle covered by a cushion plate, the one in the middle Has predetermined breaking lines as tear edges, which by the unfolding gas cushions are destroyed. At over these tear edges become predominantly radial gas outlet but insufficiently applied, so that unwanted Uncontrollable cracks appear on the pad standing, which may to an undesirable detachment of scraps of upholstery.
Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, hier Abhilfe zu schaffen und trotz der radialen Abström öffnungen des Gasgenerators ein gezieltes Öffnen der Polsterabdeckung ohne Gefahr eines Ablösens von Teilen der Abdeckung sicherzustellen.The present invention was therefore based on the object to remedy this and despite the radial outflow openings of the gas generator a targeted opening of the Upholstery cover without risk of parts coming off the cover.
Dies wird bei einem gattungsgemäßen Gasgenerator erfindungs gemäß dadurch erreicht, daß im Abstand vor den Abström öffnungen ein Prallblech zum im wesentlichen axialen Ablenken der ausströmenden Gase angeordnet ist.This is fiction, in a generic gas generator according to achieved in that the distance before the outflow openings a baffle to the essentially axial Deflecting the escaping gases is arranged.
Der Gegenstand der Erfindung soll im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbei spieles näher erläutert werden.The subject matter of the invention will be described in the following of an embodiment shown in the drawing game will be explained in more detail.
In der Zeichnung zeigen:The drawing shows:
Fig. 1 einen Vertikalschnitt durch eine im Bereich eines nicht dargestellten Lenkrades eines Kraft wagens eingebaute Gaskisseneinheit, und Fig. 1 shows a vertical section through a gas cushion unit installed in the area of a steering wheel, not shown, of a motor vehicle, and
Fig. 2 in größerem Maßstab eine Einzelheit aus Fig. 1. FIG. 2 shows a detail from FIG. 1 on a larger scale.
Ein rotationssymmetrischer Gasgenerator 1 mit radialen Abströmöffnungen 2 ist über Niete 3 bzw. Schrauben 4 an einem Generatorträger 5 befestigt. Der Generatorträger 5 bildet den Gasgenerator 1 umgebende Taschen 6 zur Auf nahme nicht dargestellter Faltlagen eines Gaskissens 7, das durch einen gleichfalls durch die Niete 3 und Schrauben 4 beaufschlagten Ring 8 befestigt ist.A rotationally symmetrical gas generator 1 with radial outflow openings 2 is fastened to a generator support 5 via rivets 3 or screws 4 . The generator support 5 forms the gas generator 1 surrounding pockets 6 for taking on not shown folded positions of a gas cushion 7 , which is fastened by a ring 8 also acted upon by the rivet 3 and screws 4 .
Auf den Generatorträger 5 ist eine Polsterplatte 9 auf geclipst, die Sollbruchlinien 10 aufweist, die durch das sich entfaltende Gaskissen 7 aufgerissen werden und ein Austreten des Gaskissens 7 gestatten.A cushion plate 9 is clipped onto the generator support 5 , which has predetermined breaking lines 10 , which are torn open by the gas cushion 7 that unfolds and allow the gas cushion 7 to emerge.
Um ein mittiges Beaufschlagen der Unterseite der Polster platte 9 durch das aus den radialen Abströmöffnungen 2 ausströmende Gas sicherzustellen, ist im Abstand vor den Abströmöffnungen 2 ein Prallblech angeordnet, das von einem abgewinkelten Schenkel 11 des Ringes 8 gebildet wird. Der Strömungsverlauf des austretenden Gases ist in Fig. 2 der Zeichnung durch Pfeile 12 angedeutet.About a central applying the underside of the cushion plate 9 ensure by the flowing out of the radial outflow openings 2 gas, at a distance in front of the discharge openings 2, a baffle plate is arranged, which is formed by an angled leg 11 of the ring. 8 The flow pattern of the escaping gas is indicated by arrows 12 in FIG. 2 of the drawing.
Es wäre auch denkbar, das Prallblech durch einen Schenkel eines separaten Winkelringes zu bilden, der auf den das Gaskissen haltenden Ring aufgesetzt und mit diesem ver bunden ist.It would also be conceivable to pass the baffle through one leg to form a separate angle ring, which on the Gas ring holding ring placed and ver with this is bound.
