Body generator and a kind of air bag including such gas generator.
Background technique
Gas generator is widely used in security technology area, is especially applied in air bag.In addition, for example
It can also apply in belt with pre-load device.Air bag for motor vehicle generally includes gas generator and sends out with gas
The expandable airbag of raw device connection.When emergency occurs in operation for motor vehicle, such as collides or overturn, gas occurs
Device can be triggered and to generate a large amount of gas rapidly, and gas is filled into expandable airbag, and the airbag of expansion rises
To the effect of protection vehicle occupant.
In some gas generators, gas can be generated and gas generant composition in accordance point is quick-fried, this gas generator can be with
Referred to as firework type gas generator.In some gas generators, ignition charge can be arranged around igniter, wherein
Ignition charge can be ignited device and light, and the ignition charge then to burn leads to lighting and burning for gas generant composition in accordance.Ignition charge can be with production
Gas medicine in the same manner or is differently composed.Such as ignition charge can have better inflammability than gas generant composition in accordance.Occur in some gases
In device, it can be generated largely by mixing at least two components and by the chemical reaction of these back to back components
Gas.
A kind of gas generator as known to patent document CN204279333U comprising shell and be directly injection-moulded on shell
The quick-fried device module of point.Present inventor has found under study for action, has the following deficiencies: in this gas generator
1., may be between injection molding body and the metal surface of shell due to the cooling of injection molding body in injection molding process
Form gap, it is thus possible to influence the sealing performance of gas generator.When the moisture in atmosphere invades gas by gap
Behind generator inside, gas generant composition in accordance may be made to fail, to influence the working performance of gas generator.Gas generator even can
Energy is entirely ineffective or has the risk exploded at any time.
2. passing through at shell in the lead for putting quick-fried device, injection molding body can have the cylindrical body that a diameter is several millimeters.Such as
Fruit generates gap between injection molding body and the surface of shell of metal, it would be possible that pulling force will be applied directly on the cylindrical body.
Since the cylindrical body has small cross section, which may have insufficient tensile strength.If in injection moulding process by
Some small cavities are formed in the center of the cylindrical body in cooling, then the insufficient defect of tensile strength will be more serious.
