It means that thrust is zero . That is, the gas discharge openings of the inflator, Ugasu by force to physically move the Lee Nfureta does not occur is placed so as to be discharged in the opposite direction. Therefore, the inflator usually consumes the generated energy at a predetermined position.

[0004]

BACKGROUND OF THE INVENTION Availability of the prior art is shown <br/> in the following US Pat. Patent No. Issue Date Patentee 3,414,292 December 3, 1968 S. Oldberg et al 3,715,131 February 6, 1973 EK Hurley et al 3,880,447 April 29, 1975 WF Thorn et al 4,332,398 June 1, 1982 GR Smith 4,817,828 April 4, 1989 GW Goetz 4,832,300 June 27 , 1989 JF Zionmek et al. 4,941,678 July 17, 1990 DR Lauritzen et al.

[0005] Oldberg et al patents attached by clamps, the vehicle occupant having a inflatable crash bag which is folded to surround firmly long cylindrical diffuser member discloses a safety device Ru coercive Mamorusu.
Diffuser member, an inflator comprising a fluid container of the internal reservoir to form the placed Ru chamber concentrically. In order to provide a tight seal, inside the reservoir, the end of both sides
Bordered sheet over beam penetration into the diffuser member in section. When activated by explosive means, fluid from the container
The air flows rearward from only one side of the inflator toward the inner wall near the diffuser member. The stream is split and discharged forward through a single row of longitudinally spaced openings on only one side of the diffuser member toward the stationary baffle member. Baffle member, the fluid was divided, Keru countercurrent fluid again backwards towards the inflatable air bag.

[0006] In the assembly and construction of inflatable devices for protecting occupants in a vehicle, the inflator causes potentially greater risk. Send transportable, storage, and during installation
Accidental activation of the safety equipment could result in harm to humans.
Along with the department, to spawning a specific damage especially when it is not inflator is thrust neutral type. Therefore, in order to minimize the potential for injury and damage such as this, less handling amount inflator is subjected to assembly and during the construction of the safety device
It is desirable to do. Mounting the inflator Te <br/> a final working of the assembly of the safety device substantially reduces the risk of injury and damage. With the thrust neutral type inflator, in further reducing the risk of the harm and injury
I can .

[0007] The structure of Oldberg these safety devices, was omitted by attaching the Lee Nfureta as the final work of the device assembly
Things . Particularly inflatable air bag is provided in the diffuser member surrounds it firmly teeth relationship, inflator, i.e. the internal reservoir within the diffuser member at its end

The Hurley et al. Patent discloses a collapsible inflatable bag surrounding a gas generator having an open stern end closed by a closure plate and a cylindrical head assembly having a closed end. . Orifice centrally located normally closed by rupture disc is provided in the closing plate. Diffuser positioned concentrically with closed end shape dished head provides an annular cavity the cylindrical portion of the f Tsu <br/> de assembly enclosed Mutame, around the gas generator. When gas generator is actuated, because rupture disc is released in accordance with the pressure of the head assembly exceeding the burst pressure of the rupture disk, the generated gas is made possible flow out of the orifice of the closure plate of the stern end of the gas generator made possible collision with the inner <br/> wall Difuyu tHE end. This causes the gas to be dispersed within the annular cavity and out through a plurality of openings spaced around the diffuser wall. The operation is not thrust-neutral due to the outgassing of the generated gas out of the stern end of the gas generator. Also the structure of Hurley, preparative gas generator as a final work of the assembly
It is not possible to manufacture devices such as mounting .

The Thorn et al. Patent discloses a collapsible inflatable bag that is placed in intimate contact with a long cylindrical gas generator. The gas generator comprises a row of gas outlet ports extending 360 degrees around the cylinder. Gas exchange
Was arising thrust counteracting being discharged in the opposite direction to have
Because, it is a thrust neutral. Plate semi-cylindrical shape of the container for guiding the gas again, are spaced between about parts <br/> component facing the front of the gas generator. The plate is forward
Inflatable again to rear the released inflation gas into an electrically rather into the bag. The redirected gas expands the bag normally is folded directly discharged as gas and co in the inflatable bag to the expanded state. Bag in storage position
Is positioned adjacent and in contact with the rear half of the gas generator. This is the final work of equipment assembly
Prevent the attachment of the gas generator Te.

The Smith patent discloses a long horizontally disposed nozzle, a concentrically long cylindrical inflator-diffuser assembly, and a collapsible inflatable cushion.
An inflatable restraint system having the same is disclosed. The inflator and diffuser are folded because disposed within the cushion, are connected to the side wall of the housing as a unit by bolts extending into tapped bosses, the boss is fixed to the unit to which it has been linked. Therefore, not only the connected unit but also the inflator cannot be mounted as a final operation in the system assembly.

In the Goetz patent , the folded airbag and long cylindrical inflator are mounted on a rigid reaction canister that is mounted on the dashboard of the vehicle, and the structure and arrangement of the exhaust port or gas exhaust opening of the inflator is activated. The most
First gas flow is guided rearward by Lee Nfureta, back
Inflate the gusset . Excess gas flows from the inflator to the front to <br/> surrounding environment. This is found towards both the front and rear side
It is achieved by Rukoto using rupturable foil layers to close the inflator exhaust ports, wherein the port directed to <br/> rear is <br/> rupture ports directed forward Explodes at a predetermined pressure lower than the pressure. Therefore, the inflator is not thrust neutral and the air
Bag for placement in close proximity to the reaction canister to the inflator, it is not possible to attach the inflator as the final working of the device assembly.

[0012] As disclosed in the patent and the other aforementioned prior art patents of Goetz, are known prior art structure for providing a container you accommodate an inflator and an airbag. Containers are generally reaction canisters
Called, it provides a medium for attaching and holding the module to the instrument panel using a suitable bracket.

[0013] The reaction canister, bag deployment
An inflator and the diffuser until, if provided, et al.
Protect the airbags if they are . In addition reaction canister is, Scripture that occurs when the server Tsu grayed is deployed
Absorbs a large load in terms of type . If the load is sufficiently absorbed, the inner portion of the vehicles, to cod particular also serious damage to the instrument panel.

[0014] A disadvantage in using the reaction canister to the air bag module in order to protect an occupant is enclosed in the instrument panel or the dashboard Ategau for mounting the module. Since usually to limit the height, to accommodate the volume of the air bag folded, rather long length of the top panel and bottom panel, namely deep. And the deployment of the airbag is restricted, and before deployment the distance is longer than desired.
You must move back and forth . Large amount of generated gas and
For required movement distance of the airbag deployment before the bag, the pressure in the reaction canister to a level that would expand to expand the vessel and is increased. This condition, known as bell mouth is broken <br/>壊的took the instrument panel, in particular disorders in other damages have low-speed collision small of the vehicle.

[0015] Zionmek et al patents and Lauritzen et al patent, in order to prevent the Airbus <br/> Tsu grayed Exhibition bell mouth open when to suppress the force distribution of the reaction canister, the use of the limit strap Disclose. This technology allows the use of lighter and cheaper reaction canisters. However <br/> while, the structural arrangement, the remaining ones to be desired with regard to directing the desirability <br/> wards complexity to manufacturing and assembly operations
In addition, it is not possible to attach the inflator in the final work of assembling the module.

[0016] Thus normally airbag module assembly of the prior art three basic configurations, i.e. 1) Transportation and cushion or air bag to be inflated by at gas and collision Shikagen velocity, 2) when activated An inflator to provide the gas used to inflate the airbag, and 3) the direction of gas from the inflator and a mounting base for mounting of the vehicle assembly, while at the same time providing the inflator and airbag. A reaction canister that typically functions as a structural housing that supports both.

Generally, a conventional inflator, for example, about 1
05 to 210 kg / cm ² (about 1500 to 3000 ps
pressures in the range of i) usually due to the relatively high pressures generated by the pyrotechnic inflator generates, wall Lee Nfureta are typically manufactured with a relatively thick material to provide additional strength. However, as described above, conventional airbag module assemblies typically house the inflator in a reaction canister surrounded by a wall.
If you use the inflator surrounded by thick walls housed within reaction housing surrounded by walls, typically
A heavy Kunar Ri by weight is most desirable weight of the assembly.

Furthermore, if the reaction canister is normally manufactured using formed and / or melted steel, such manufacturing techniques can be used to prepare for various mountings and connections, for example, especially for the inflatable vehicle. various desirable features, such as the adaptation of the design of the restraint system for economically and efficiently incorporate do not contribute.

[0019] Further, by further emphasis on weight reduction of vehicle weight, requests for more weight with lighter inflatable restraint systems and demand has been created.

[0020] Therefore, there is <br/> request and demand relates to an improved type reaction canister for use in an air bag module for customer side of the vehicle.
