Abstract
The utility model discloses a double-airbag safety gasbag device which comprises a gas generator, and is characterized by also comprising an inner airbag, an outer airbag and a reducing valve, wherein the inner airbag is coated in the outer airbag and is communicated with the gas generator; and the outer airbag is communicated with the gas generator through the reducing valve. By utilizing double-layer airbags with different pressures, the impact of high-pressure airbag on a human body is effectively reduced; and meanwhile, enough supporting force of the airbags is guaranteed. The double-airbag safety gasbag device has the characteristics of buffer effect and simple structure, has a certain practical value, and is mainly suitable for passive safety protection of automobiles.
Description
Technical field
The utility model relates to the safety air bag of automotive use, particularly a kind of pair of airbag air bag device.
Background technology
Air bag device is widely used on automobile, has effectively alleviated occupant's extent of injury.But the air bag device that uses at present has only an air bag, for the impact of bearing human body must guarantee bigger inflation pressure and eject speed faster, easily human body is damaged.
Summary of the invention
The utility model technical matters to be solved is the defective that overcomes above-mentioned prior art, and a kind of pair of airbag air bag device is provided, and adopts different inflation pressuries to reduce the purpose of air bag device to occupant injury to arrive through internal airbag, outer airbag.
The utility model solves the technical scheme that its technical matters adopted: a kind of pair of airbag air bag device; Comprise gas generator; It is characterized in that: also comprise interior airbag, outer airbag, reducing valve; Interior airbag is wrapped in the outer airbag, is communicated with gas generator, and outer airbag is communicated with gas generator through reducing valve.
The airbag inflation pressure is higher than outer airbag inflation pressure in described.
The expanding gas that gas generator excites the back to produce, airbag in a part gets into, airbag outside a part gets into after the reducing valve step-down.The pressure of interior airbag is higher than the pressure of outer airbag, plays a supportive role, and outer airbag plays buffer action.After the collision happens, human body at first clashes into outer airbag, because outer airbag pressure is lower, has played buffer action, has reduced the injury to human body.And interior airbag pressure is higher, has played supporting role.
The utility model compared with prior art has the following advantages and good effect: owing to adopted the double-deck airbag of different pressures, effectively reduced the impact of high pressure airbag to human body, simultaneously, guaranteed that also airbag has enough bearing forces.
It is good to the utlity model has buffering effect, and characteristic of simple structure has certain practical value.
Description of drawings
Fig. 1 is the schematic diagram of the utility model
Among the figure: 1, outer airbag 2, interior airbag 3, reducing valve 4, gas generator
The specific embodiment
In the utility model schematic diagram shown in Figure 1, interior airbag 2 is wrapped in the outer airbag 1, and interior airbag 2 is communicated with gas generator 4, and outer airbag 1 is communicated with gas generator 4 through reducing valve 3.The inflation pressure of interior airbag 2 is higher than the inflation pressure of outer airbag 1.
The expanding gas that gas generator 4 excites the back to produce, in the airbag 2, in the airbag 1, the pressure of airbag 2 was higher than the pressure of outer airbag 1 in making outside a part got into after reducing valve 3 step-downs in a part got into.Like this, interior airbag 2 is just played a supporting role, and 1 of outer airbag plays buffer action.After the collision happens, human body at first clashes into outer airbag 1, because outer airbag 1 inflation pressure is lower, has played buffer action, avoids the directly interior airbag 2 of bump of human body, has reduced the injury to human body.
Claims (2)
1. a two airbag air bag device comprises gas generator, and it is characterized in that: also comprise interior airbag, outer airbag, reducing valve, interior airbag is wrapped in the outer airbag, is communicated with gas generator, and outer airbag is communicated with gas generator through reducing valve.
