Abstract
The utility model provides a layering buffering formula air bag belongs to motor vehicle safety airbag technique field, the utility model discloses to motor vehicle driver and crew's impact injury in the time of can effectively reducing motor vehicle air bag and pop out. This gasbag includes the air bag main part, and the hole is aerifyd to gasbag interlayer, high pressure balloon, high pressure balloon, the low pressure gasbag, and the hole is aerifyd to the low pressure gasbag. Its characterized in that: the air bag main part is separated for high pressure balloon and low pressure gasbag by the gasbag interlayer, high -pressure gas aerifys the hole through high pressure balloon and fills into high pressure balloon when car gas generator aerifys to air bag, by the gasbag interlayer through filtering the decompression, it gets into the low pressure gasbag to aerify the hole by the low pressure gasbag again, when human body striking air bag, at first contact and be located the more mild low pressure gasbag in air bag upper strata, the buffering gasbag is to the impact velocity of human body, the high pressure balloon who later is located air bag lower floor bears the impact force after the buffering again, thereby ensure human safety.
Description
Technical field
The utility model provides a kind of hierarchical buffering type air bag, particularly belongs to a kind of hierarchical buffering type air bag
Technical field.
Background technology
Air bag refers to the soft capsule of inflation being arranged on automobile, is a kind of protection system of passive safety, it and seat
Safety belt uses cooperatively, and can provide effective Anti-bumping protection for occupant.
The principle of air bag is in vehicle traveling process, and sensing system constantly changes letter to control device transmission speed
These information are analyzed judgement by control device by breath, if the acceleration surveyed, velocity variable or other index exceed
Predetermined value really there occurs collision, then control device sends out to gas that body generator sends ignition order or sensor directly controls
Igniting.There is explosive reaction after igniting, produce nitrogen or compressed nitrogen in air accumulator is discharged full of collision airbag, when driving
When taking advantage of personnel to contact with airbag, by the braking absorption collision energy of airbag upper air-vent, reach the purpose of protection occupant.
Air bag system will wash air bag cover plate open when starting, and launch inflation in moment, and process about only needs to
0.03 second, air bag then can be ejected with the speed of about 300km/h, and thus produced impact there are about 180 kilograms, this for
Can be difficult to bear for the more fragile position of the human body such as head, neck and eyes and inner ear, thus causing either large or small injury.
Prior art creates corresponding novel safety airbag for the problems referred to above, that is, release pressure security airbag apparatus and
Air bag device of gradable inflation etc..Release pressure security airbag apparatus add pressure relief device, in driver and crew
When head encounters air bag, air bag starts to be vented by the pore of balloon surface, and the discharge of gas has certain speed,
Guarantee to allow the body part of people lentamente to slow down, to avoid major injury.And the air bag device of gradable inflation, i.e. gas
Generator divides two-stage point quick-fried, and the first order produces about 40% gas volume, and far below maximum pressure, produce mobile to head part is delayed
Punching acts on, the quick-fried generation residual gas of second level point, and reaches maximum pressure.Because the quick-fried maximum pressure of two-stage point is less than single-stage
Quick-fried, this form of point, pressure is stepped up, thus avoiding air bag moment to be full of the impact injury to human body.
But release pressure security airbag apparatus are the remedial measures after air bag ejects to be filled it is impossible to be prevented effectively from air bag
The injury to human body for the gas moment.And the air bag device of gradable inflation needs accurately software and hardware to control facility, institute
With expensive, only it is equipped with sedan limousine at present.
Content of the invention
For the drawbacks described above of prior art, the utility model provides a kind of hierarchical buffering type air bag, can effectively subtract
Little air bag injures to the impact of human body, thus ensureing the personal safety of motor vehicle driver and crew.And the utility model exists
Be not required in prior art basis to do big change and can install and use on vehicle because can make full use of existing mature technology and
Equipment so safe and reliable, cheap, promote by convenience.
A kind of hierarchical buffering type air bag, including air bag main body and be arranged on high-pressure gasbag in air bag main body and low
Pressuring gasbag, high-pressure gasbag side is connected with high-pressure gasbag air-filled pore, and high-pressure gasbag air-filled pore is connected with air bag gas generator
Connect.
High-pressure gasbag opposite side is connected with air bag interlayer, and air bag interlayer is provided with low pressure air bag air-filled pore one to multiple,
High-pressure gasbag is wanted to connect with low pressure air bag by the low pressure air bag air-filled pore on air bag interlayer.
Brief description
Fig. 1 is hierarchical buffering type air bag sectional side view.
Fig. 2 is hierarchical buffering type air bag orthogonal view.
Specific embodiment
Describe specific embodiment in conjunction with accompanying drawing in detail as follows：
A kind of hierarchical buffering type air bag, its structure as depicted in figs. 1 and 2, described airbag body（1）, setting
There is high-pressure gasbag（2）With low pressure air bag（3）.
Described high-pressure gasbag（2）Side and high-pressure gasbag air-filled pore（4）It is connected, high-pressure gasbag air-filled pore（4）And air bag
Gas generator（5）It is connected.
Described high-pressure gasbag（2）Opposite side and air bag interlayer（6）It is connected, air bag interlayer（6）It is provided with low pressure air bag to fill
Pore（7）, low pressure air bag air-filled pore（7）With low pressure air bag（3）It is connected.
Described high-pressure gasbag（2）By air bag interlayer（6）On low pressure air bag air-filled pore（7）With low pressure air bag（3）Think even
Logical, air bag interlayer（6）Can be according to air bag main body（1）Thickness arrange one layer to several layers, the more buffering effects of the number of plies are better.
When vehicle is clashed into other objects, cause air bag gas generator（5）Produce gases at high pressure, gases at high pressure pass through height
Pressuring gasbag air-filled pore（4）, make high-pressure gasbag（2）Expand, gases at high pressure impact air bag interlayer simultaneously（6）And by air bag interlayer（6）
Stop, reduce pressure as low-pressure gas, low-pressure gas is according to low pressure air bag air-filled pore（7）Size and quantity number by a certain percentage
It is filled with low pressure air bag（3）, make low pressure air bag（3）Expand, low pressure air bag（3）Speed of expansion and expand dynamics all in proportion
Less than high-pressure gasbag（2）.
As automobile driver and crew because Vehicular impact inertia hits air bag main body（1）When, first shock be speed of expansion and
The all less low pressure air bag of the bulbs of pressure（3）, thus harmless carry out to human body buffering for the first time, reduce human body inertia force it
Second clashes into speed of expansion and the larger high-pressure gasbag of the bulbs of pressure afterwards（2）, by high-pressure gasbag（2）Isolation human body is to Automobile
The shock of body, afterwards, high-pressure gasbag（2）Exit first, low pressure air bag（3）Continue to bear human pressure, in high-pressure gasbag（2）Put
Gas low pressure air bag to certain proportion（3）Also and then exitting, completing entirely to protect process, thus protecting the people of automobile driver and crew
Body safety.
