Abstract
The utility model creates the air bag gas generator providing a kind of adjustable inflatable amount, comprise gas generator, distributing valve, air bag inflator mouth and gas generator leakage port, described gas generator is connected with distributing valve, described distributing valve is respectively equipped with air bag inflator mouth and gas generator leakage port.The utility model creates the good effect had: according to the different factor adjustments of gas producer such as height, body weight, build of occupant to the charge air of airbag; even if when passenger and standard occupant differ greatly; occupant restrain system can protect occupant preferably, is of value to and reduces extent of injury suffered by personal casualty ratio and occupant in road traffic accident.
Description
Technical field
The invention belongs to technical field of vehicle safety, especially relates to a kind of air bag gas generator of adjustable inflatable amount.
Background technology
When Passenger motor vehicle occurs to endanger the collision of occupant safety in arteries of communication process, in its car, safety air bag will be opened automatically, avoids occupant to be subject to severe impact and collision by gas generator to air bag inflator.By having carried out reasonable selection to air bag gas generator, vehicle can ensure that standard dummy obtains best protected effect in an impact in the design process.But Passenger motor vehicle has only carried out the Configuration selection and optimal match of air-cushion inflator for standard occupant in the design at present; can not for the automatic adjustments of gas producer of factor such as different heights, body weight, build of internal members to the charge air of airbag in daily traffic accident; cause passenger and the standard occupant occupant restrain system when the factors such as height, body weight, build differ greatly better can not protect occupant if Here it is, even can increase the weight of the injury situation of occupant.
Summary of the invention
The problem that the invention will solve is the use by a kind of New Type of Gas Generator, air bag is made can, according to factor conservative control gas generators such as occupant's height, body weight, builds to the charge air of airbag, to enable air bag ensure the safety of interior passenger to greatest extent when there is traffic accident.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: a kind of air bag gas generator of adjustable inflatable amount, comprises gas generator and distributing valve, and described distributing valve is connected with the air extractor duct of gas generator.
Preferably, described distributing valve is respectively equipped with air bag inflator mouth and gas generator leakage port.
Preferably, described gas generator is multi-stage gas generators.
Preferably, also comprise gas distributing chamber, described gas distributing chamber is connected with the air extractor duct of multi-stage gas generators, and described distributing valve is placed in gas distributing chamber inside.
Preferably, described gas distributing chamber is respectively equipped with air bag inflator mouth and gas generator leakage port.
Preferably, described distributing valve is electromagnetic valve.
The advantage that the invention has with good effect is: according to the different factor adjustments of gas producer such as height, body weight, build of occupant to the charge air of airbag; even if when passenger and standard occupant differ greatly; occupant restrain system can protect occupant preferably, is of value to and reduces extent of injury suffered by personal casualty ratio and occupant in road traffic accident.

Detailed description of the invention
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
First embodiment:
As shown in Figure 1, a kind of air bag gas generator of adjustable inflatable amount, comprise gas generator 1 and distributing valve 2, described distributing valve 2 is connected with the air extractor duct of gas generator 1, also comprise air bag inflator mouth 3 and gas generator leakage port 4, described distributing valve 2 is respectively equipped with air bag inflator mouth 3 and gas generator leakage port 4.A distributing valve 2 is installed additional at gas generator 1 air extractor duct; control with unlatching size the gas flow entering airbag by the opening time of this distributing valve 2; and then control degree of inflation and the inflationtime of air bag; when reaching desired gas amount; discharged by gas generator leakage port, reach the effect all can better protected different building shape occupant.
Second embodiment:
As shown in Figure 2, when gas generator 1 according to the first embodiment is multi-stage gas generators 10, comprise multi-stage gas generators 10, distributing valve 2, gas distributing chamber 5, described multi-stage gas generators 10 comprises first order gas generator 11, second stage gas generator 12, n-th grade of gas generator 13, described first order gas generator 11, second stage gas generator 12, the air extractor duct of n-th grade of gas generator 13 is connected with gas distributing chamber 5 successively, it is inner that described distributing valve 2 can be placed in gas distributing chamber 5, described gas distributing chamber 5 is respectively equipped with air bag inflator mouth 3 and gas generator leakage port 4.When using multi-stage gas generators 10; the air extractor duct of gas generator at different levels is connected with gas distributing chamber and carries out unifying distribution; control with unlatching size the gas flow entering airbag again by the opening time of distributing valve 2; and then control degree of inflation and the inflationtime of air bag; when reaching desired gas amount; discharged by gas generator leakage port 4, reach the effect all can better protected different building shape occupant.
Distributing valve 2 can use continuous break-make Controlling solenoid valve or openings of sizes controollable Valve controlling can be entered the gas flow of air bag by air bag inflator mouth 3 in actual use.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
