Definitions
- the invention relates to a diffuser for a gas generator of a gas bag module, which has an outer wall which encloses the gas generator in the circumferential direction at least in an outflow region, wherein the outer wall has a substantially longitudinal interrupting edge and is bent during activation of the gas generator along this interrupting edge and defines an outflow direction for the gas.
- Gas bag modules have diffusers which serve to influence the inflation behavior of the gas bag and to swirl the gas flowing out of the gas generator in order to protect the gas bag fabric from direct flow of the hot gas. Diffusers are known from the prior art, which surround the gas generator in a discharge area. After activation of the gas generator they are opened completely or partially by the resulting pressure wave.
- the diffuser defines an outflow opening through which the gas can flow into the gas bag.
- the lying behind the diffuser region of the airbag fabric is protected from direct flow of hot gas, while the guided through the discharge gas stream is fluidized, so that a cooling of the gas and a uniform increase in pressure takes place in the gas bag.
- the Verwirbelungseigenschaften these diffusers are, however, inadequate, so that the airbag fabric must often be protected by additional protective layers.
- the gas flow is merely deflected, so that the pressure wave of the gas generator or the hot gas impinges directly on the airbag fabric.
- the object of the invention is to provide a diffuser for a gas generator of a gas bag module, which allows a more effective turbulence or deflection.
- gas guide elements which influence in the bent state of the diffuser, the outflow direction of the gas emerging from the gas generator.
- the influence of the outflow direction or of the outflowing gas takes place according to the invention not only by the shape of the diffuser in the bent state, but also by additional gas guide. These cause an effective influence, for example, a more targeted deflection or additionally acting for deflection turbulence of the gas flow.
- the gas guide elements may be formed, for example, such that the gas flow is directed away from the airbag fabric and is additionally swirled. As a result, the pressure wave generated by the gas generator is weakened, so that a uniform pressure increase takes place in the gas bag.
- the gas is cooled by the mixing, before this impinges on the airbag fabric.
- the gas flow thus does not impinge on the airbag fabric as a directed stream, but due to the swirling, a uniform pressure increase is achieved in the interior of the airbag.
- the gas guide elements can be, for example, projections and / or recesses provided on the inside of the diffuser. Through this an uneven reflection surface is formed on the inside of the diffuser through which no directed reflection of the gas flow takes place. Rather, the gas flow is deflected depending on the impact point on the inside in different directions, so that an effective turbulence is achieved. Through the outflow opening, which defines the diffuser in the bent state, the swirling gas is directed in the direction of the gas bag, even with a turbulence, so that a targeted inflation of the gas bag takes place.
- the projections and / or the depressions are for example punctiform, for example circular or angular.
- the side surfaces of such a punctiform gas guide element are designed to be sloping down to different sides, so that different angles of reflection result for the impinging gas flow, by which a particularly good turbulence is generated.
- the projections and recesses are linear and extend in particular in the axial direction with respect to the longitudinal direction of the diffuser.
- line-shaped projections or depressions may, for example, be arranged at regular intervals so that they form a wave profile in an axial cross-section.
- the projections or depressions can be formed particularly easily by embossing the outer wall. That is, the diffuser is made of a deformable material, and the recesses or protrusions are individually adjusted in a subsequent manufacturing step. This embossing also requires no additional material to be applied or removed to form the depressions or protrusions. Since the thickness of the outer wall is not changed substantially during embossing, that is, the outer wall after embossing substantially the same thickness, the stability of the diffuser is not affected, so that the deformation properties in particular during bending of the diffuser upon activation of the gas generator Corresponding deformation properties of a conventional diffuser.
- the outer wall is bent radially inwardly at the interrupting edge.
- the gas flow usually impinges on the outer wall and is guided essentially along this outer wall in the direction of the outflow opening and subsequently into the gas bag.
- the radially inwardly bent interruption edge deflects this gas flow in front of the outflow opening again inwards, so that this is additionally swirled before hitting the airbag fabric.
- This radially inwardly bent interrupt edge at the same time a portion of the gas stream is redirected in the axial direction.
- the wider the radially inwardly bent interrupt edge the greater the proportion of the axial directed gas flow.
- the proportion of the axially flowing gas is also adjustable by the angle of the bend. This gas distribution is possible, which can otherwise be achieved only by a closed diffuser. Compared with closed, tubular diffusers such diffusers can be produced more cheaply.
- the interruption edge When viewed in the axial direction, the interruption edge can also be designed wave-shaped, with this irregular edge additionally causing refraction or scattering of the gas flow.
- the gas guide elements are formed by recesses provided in the outer wall, in particular oblong, or slits extending in the axial direction. Through these slots, a small proportion of the outflowing gas can escape from the diffuser. Due to the expansion behind the slots, a strong slowing down of the gas flow and thus a strong turbulence takes place.
- the slots are preferably designed so narrow that only a small proportion of the gas flowing out of the gas generator can escape through these slots, so that even in this embodiment, after activation of the gas generator within the diffuser, a strong pressure increase takes place, through which the diffuser is bent ,

- FIG. 2 shows a sectional view through the gas generator from FIG. 1 in the area of the diffuser
- FIG. 3 shows the sectional view from FIG. 2 in the opened state of the diffuser
- FIGS. 4 a) to c) show a perspective view of a first embodiment of a diffuser according to the invention and in each case a sectional view through a gas generator with a closed and bent diffuser
- FIGS. 5 a) to c) show a second embodiment of a diffuser according to the invention in a perspective view and in each case a sectional view through a gas generator with a closed and bent diffuser
- FIGS. 6 a) to c) show a third embodiment of a diffuser according to the invention in a perspective view and in each case a sectional view through a gas generator with a closed and bent diffuser,
- FIG. 8 shows a fifth embodiment of a diffuser according to the invention in a perspective view.
- FIG. 1 shows a gas generator 10 for a gas bag of a vehicle.
- the gas generator 10 has a substantially elongated shape with an outflow region 12, which is arranged on the right with respect to FIG.
- the outflow region 12 is designed such that the gas can flow out with respect to the longitudinal axis L of the gas generator 10 in the radial direction (see also FIG. 3) and in the axial direction (see FIG. 1).
- the outflow region 12 is here surrounded by a diffuser 14 which has a substantially cylindrical outer wall 16 which completely covers the outflow region 12 of the gas generator 10 in the axial direction and encloses it in the radial direction (see FIG. 2).
- the gas generator 10 is arranged at least with the outflow region 12 and the surrounding diffuser 14 within a gas bag 20 in order to fill it with a gas when the gas generator is activated (FIG. 3).
- the gas generated by the gas generator 10 flows out through the discharge area 12 in the axial and radial directions. Due to the resulting pressure wave of the diffuser 14 and the pressure rise in the interior of the diffuser 14, the outer wall 16 is bent away from the interrupt edge 18 away. In this bent state, the diffuser 14 forms a cup-shaped trough, which defines an outflow opening 19, through which the gas can flow into the airbag 20. As can be seen in particular in FIG. 3, part of the outflowing gas strikes the bent-up diffuser 14 and is deflected by it. The gas flowing downwards and laterally out of the gas generator with respect to FIG. 3 impinges on the outer wall 16 and is deflected in the direction of the outflow opening 19.
- the underlying tissue behind or behind the outer wall 16 is thereby protected from the direct pressure wave of the effluent gas from the gas bag 20, since the gas is deflected upward into the airbag 20.
- the pressure wave is attenuated by the bending of the diffuser 14, so that a more uniform pressure increase takes place in the gas bag.
- protective measures must be taken to protect the fabric in the area where the gas stream impacts the airbag fabric. Usually additional protective layers on the inside of the airbag 20 are provided for this purpose.
- gas guide elements are provided on the diffuser 14 or on the outer wall 16 of the diffuser 14 according to the invention. This results in an additional deflection of the gas stream, wherein a directed gas flow is prevented by the shape and the arrangement of the gas guide.
- the gas flow through these gas guide elements as explained below, swirled more effectively, so that no directed pressure wave impinges on the airbag fabric, but a more uniform increase in pressure in the airbag 20 is effected.
- this cooling takes place a cooling of the hot gas.
- the gas-conducting elements are formed by inwardly projecting projections 24 distributed on the inner side 22 of the outer wall 16.
- the projections 24 are here formed by embossing and formed substantially point-shaped.
- the inside 22 of the diffuser 14 on an uneven reflection surface. Due to the conical peripheral surface 25 of the projections 24 takes place depending on the impact point of the gas flow an irregular deflection of the gas flow. Due to the uneven reflection is a very effective turbulence, so that a very good mixing of the gas flow and the formation of a directed gas flow is prevented on the gas bag fabric.
- the swirling gas flow increases along the outer wall 16 or after exiting the discharge opening 19 along the gas bag inner wall upwards, whereby a uniform deployment of the airbag 20 is ensured by the uniform pressure increase.
- the shape of the punctiform projections 24 or depressions can be adapted as desired. These may be, for example, spherical, conical or pyramidal.
- the gas-conducting elements are formed by linear projections 24 which extend in the axial direction with respect to the longitudinal axis L of the diffuser. As can be seen in particular in FIGS. 5 b) and c), these linear depressions are likewise produced by embossing, wherein the projections 24, viewed in an axial cross section, form a corrugated profile.
- the gas flow of the gas generator is also reflected in this embodiment by the inner wall of the diffuser, whereby due to the different angle of incidence caused by the wave profile, a swirling, upwardly directed gas flow is produced.
- the wave profile is designed so that the gas flow after the turbulence with respect to Figure 5 c) is deflected upward and rises along the gas bag wall upwards.
- the outer wall 16 of the diffuser 14 is essentially planar.
- the gas guide elements are formed here at the interrupt edge 18 by this is bent radially inwardly.
- the gas flowing out of the gas generator 10 would occur on the inside of the diffuser 14 and be deflected by it so that the gas flows upwards into the gas bag 20 along the inside of the diffuser (see, for example, also FIG. 5 c).
- the radially inwardly bent interrupt edge 18 of the gas stream is deflected radially inwardly in front of the outflow 19 (see Figure 6c), so that it is mixed with the upwardly exiting gas or swirled with this.
- the gas-conducting elements are formed by slots 26 extending in the longitudinal direction L. These slots 26 are so narrow that only a small proportion of the gas flowing out of the gas generator can flow through them. Since the space behind the slots 26 is greatly expanded, the gas flow through the slots 26 behind the slots 26 is greatly slowed down and thereby greatly swirled. Upon activation of the gas generator 10, despite the slots 26 due to the increasing pressure of the diffuser 14 is bent so that it forms a shell shape.
- the swirling effect is additionally reinforced by a wave-shaped interrupting edge 18, which serves as a refractive edge for the outflowing gas.
- the embodiments illustrated here can also be combined with one another in order to bring about a specific influence on the gas flow. It is conceivable, for example, for the diffuser 14 to have depressions or projections 24 as well as an interrupt edge bent over inwards.
