Definitions

  • the invention relates to a gas generator for airbags.
  • Known gas generators have an ignition charge, for example a solid charge, in a combustion chamber and a compressed gas in a storage chamber.
  • an ignition element ignites the primer charge.
  • the resulting fuel gas accelerates a piston, which destroys an inlet closure of the storage chamber, so that the fuel gas flows into the storage chamber.
  • an outlet closure of the storage chamber is destroyed by the piston, so that the gas from the storage chamber gets into a diffuser and from there into the airbag.
  • the object of the invention is to simplify the sealing of gas generators.
  • the storage gas chamber is formed by a thin-walled inner container which, after being filled with the compressed gas, can be easily sealed, but which does not independently withstand the pressure of the compressed gas contained in the inner container.
  • the thin-walled inner container is surrounded by a thick-walled, pressure-resistant housing.
  • the housing only has to absorb the pressure of the compressed gas, but it must not be designed so that it can be sealed.
  • the housing can thus be constructed considerably more simply. For example, a cover of the housing no longer has to be welded tightly to the housing, but can be connected by flanging, clinching or rolling.
  • the inner container preferably has at least one deformation region. Dimensional tolerances that occur when the housing or the inner container are manufactured can thus be compensated for, so that the filled inner container always lies completely against the inner wall of the housing. This ensures that the inner container does not have to absorb the gas pressure or only has to take it up in a few places.
  • the deformation region can be designed, for example, as a circumferential bead pointing into the interior of the inner container.
  • the bead is preferably provided in the vicinity of a weld seam that also runs all the way round. Thus, the bead additionally serves to relieve the weld seam when filling the inner container.
  • Fig. 2 shows a longitudinal section of a second embodiment of a gas generator.
  • an inner container 11 is provided in an essentially tubular housing 10, the interior of which forms a storage chamber 12.
  • the housing 10 is fixedly connected to a head piece 13, in which two ignition sets 14, 14 a are arranged in a combustion chamber 15, 15 a.
  • Each primer 14, 14a each has a solid charge 16, 16a.
  • the two ignition charges 14, 14a form an ignition charge 17.
  • the solid charges 16, 16a can be ignited by ignition elements 20, 21.
  • the ignition elements can be ignited electrically by a control part (not shown). They each contain an ignition charge that burns off and thereby ignites the associated solid charge 16 or 16a.
  • the housing 10 has an attachment designed as a diffuser 22. After opening the inner container 11 described later, the compressed gas present in the storage chamber 12 flows through openings 23 of the diffuser 22 into the airbag.
  • the ignition element 20 is first ignited electrically. By igniting the solid charge 16 fuel gas develops. This increases the pressure on an inlet closure 25 of the inner container 11 in the combustion chamber 15 and an intermediate chamber 24. When the pressure in the intermediate chamber 24 is sufficient, the predetermined breaking points 26 delimiting the inlet closure 25 break open.
  • a head part 31 of a piston 32 located in an inlet opening 30 of the head piece 13 is moved to the right in FIG. 1 after the predetermined breaking points 26 have been broken open by the gas pressure prevailing in the intermediate chamber 24.
  • a foot part 33 of the piston 32 is pressed into an outlet opening 34 of the housing 10.
  • the foot part 33 of the piston 32 presses against an outlet closure 35 of the inner container 11.
  • predetermined breaking points 36 of the outlet closure 35 are broken open, so that the outlet opening 34 of the housing 10 is opened.
  • the compressed gas contained in the storage chamber 12 thus flows through the outlet opening 34 into the diffuser 22 and through its openings 23 into the airbag.
  • the second solid charge 16a can be ignited by means of the ignition element 21 at any time after opening the inlet opening 30.
  • the fuel gas which forms in the combustion chamber 15a and an intermediate chamber 40 acts on a second inlet closure 41 of the inner container 11. If there is a sufficient pressure difference between the storage chamber 12 and the intermediate chamber 40, the second inlet closure 41 is opened by predetermined breaking points 42 breaking open. Thus, the fuel gas generated by the solid charge 16a can flow into the storage chamber 12.
  • the inner container When assembling the gas generator, the inner container is first produced from two cup-shaped parts 45, 46 by means of a weld seam 47 running on the circumference. To compensate for dimensional tolerances, the inner container 11 has a deformation region in the form of a bead 48 pointing into the interior of the inner container 11, which is arranged all around in the region of the weld seam 47 to relieve the weld seam 47. The inner container 11 is then inserted into the housing 10 from the left in FIG. 1 and the housing 10 is closed with the head piece 13. For this purpose, the head piece 13 has a foot 50, the outer diameter of which corresponds to the inner diameter corresponds to an opening 49 of the housing 10. Tabs 52 of the housing 10 are bent into a circumferential groove 51 of the foot 50. In order to be able to absorb the pressure later prevailing in the storage chamber 12, an edge 53 of the housing 10 is crimped around an upper edge 54 of the foot 50.
  • the primers 14, 14 a have not yet been inserted into the head piece 13.
  • the inner container 11 has a shoulder 56 pointing into a cylindrical opening 55 of the foot 50 of the head piece 13. After filling, the neck 56 of the inner container 11 is closed, for example by means of laser welding.
  • the two primer sets 14, 14 a are inserted into the head piece 13 and held in the head piece 13 by flanging an edge 57.
  • the embodiment shown in FIG. 2 also has a housing 60 in which an inner container 61 is arranged, the interior of which forms a storage chamber 62.
  • a first opening 63 of the housing 60 is closed with a head piece 64.
  • a second opening 65 of the housing 60 is arranged opposite the first opening 63.
  • the second opening 65 is closed with a second head piece 66.
  • the housing 60 is thus designed as a hollow cylinder, the openings 63, 65 of which lie opposite one another and have the same dimensions.
  • the head piece 64 and the second head piece 66 are in accordance with the head piece 13 (Fig. 1) by flanging the housing edges 67 and 68 with connected to the housing 60 so that the housing 60 and the two head pieces 64, 66 can receive the gas pressure.
  • the inner container 61 like the inner container 11 (FIG. 1), consists of two cup-shaped parts 70, 71 welded together and likewise has a circumferential bead 72 to compensate for dimensional tolerances. Furthermore, the inner container 61 has an inlet closure 74 provided with predetermined breaking points 73, an outlet closure 76 provided with predetermined breaking points 75 and a second second inlet closure 78 also provided with predetermined breaking points 77. To fill the inner container 61 with compressed gas, the inner container 71 has a projection 80 which projects into the head piece 64 and is welded tight after filling.
  • the head piece 64 has only one ignition charge 81, which consists of an ignition element 82 and a solid charge 84 arranged in a fuel chamber 83.
  • the fuel gas generated when the solid charge 84 is burned the inlet opening 85 closed by the inlet closure 74 and, with the aid of the piston 86, the outlet opening 87 closed by the outlet closure 76, so that gas flows out the storage chamber 62 flows through the outlet opening 87 into the second head piece 66 and passes through the opening 88 thereof into the airbag (not shown).
  • a second ignition charge 90 which likewise consists of an ignition element 91 and an ignition element in a combustion chamber 92. orderly solid charge 93, is arranged in the second head piece 66.
  • the second priming charge 90 can be fired at a time relative to the first priming charge 81.
  • the predetermined breaking points 77 of the inlet opening 78 are destroyed by the pressure which arises after the ignition of the solid charge 93 and the fuel gas flows into the storage chamber 62.

Abstract

Un générateur de gaz pour airbags comporte au moins une composition d'amorçage (14, 14a) dans une tête (13). Cette composition d'amorçage contient une charge de poudre (16) amorçable par un élément d'allumage (20). Dans un carter (10) du générateur de gaz se trouve un récipient interne (11) dont l'espace intérieur forme une chambre d'accumulation (12). Lors du déclenchement du générateur de gaz, la poudre (16) produit une pression de gaz qui perce, au niveau de points destinés à la rupture (26), une ouverture d'admission (25) du récipient interne (11) à paroi mince. Ainsi, un piston (32) est mû en direction d'une ouverture de sortie (34) du carter (10). Une partie jupe (33) du piston (32) détruit, pour ouvrir l'ouverture de sortie (34), un obturateur (35) du récipient interne (11) à paroi mince. Du gaz provenant de la chambre d'accumulation (12) peut ainsi s'écouler, par l'ouverture de sortie (34), dans un diffuseur (22) et de ce dernier dans un airbag par des ouvertures (23).
