Abstract

This invention provides a supplementary restraint system (air bag) with dynamical control of inflow air to ensure a full fill-up and full unfolding of the air bag. The supplementary restraint system consists of a burning box, a gas generator, and an air bag. There is a reaction chamber with gas-composition in the burning box. When the supplementary restraint system is triggered, the gas-composition is burned to generate the working gas, and when the pressure of the working gas inside the chamber is greater than the ambient air pressure, the chocking wing will be deflected by the reverse flow of the working gas, and will close the inflow holes to prevent the gas running out of the air bag, and to ensure a full fill-up and full unfolding of the air bag.

Description of the invention: [Technical field to which the invention belongs] The present invention relates to an airbag device, in particular to an airbag device capable of dynamically controlling the state of air intake by improving the gas escape phenomenon of the airbag and fully deploying the airbag bag. . [Previous technology] An air bag device is composed of a combustion box body, a folded air bag ′, an inflatable gong, a gas generator and a gas generating agent. The principle is to sense the impact of the vehicle with foreign objects through several sets of sensors placed in the front of the vehicle or a single-point sensor used in the vehicle to determine whether the airbag should be detonated. When the vehicle is hit by a frontal impact, the instantaneous acceleration detected by this sensor exceeds a set value. The body generator will ignite the gas and generate a large amount of working gas. At this time, the airbag bag will expand instantly to prevent the driver. The head of the front passenger and the front passenger directly hit the windshield or the steering wheel of the vehicle, so as to achieve the purpose of protecting the safety of the driver and front passenger. Here is a brief description of the inflated state, the inflator can be divided into the following types ... and the mixed type " ... etc. However: At present, the amount of aerobic agent filled in the inflator depends on a lot of demand values, for example, in the "inflated state" of the airbag of the driver's seat, the gas generating agent tablets can produce about 0.000. The energy near the mouth, but actually the energy A required to inflate the entire sac is about 500 stone-absorbing energy, so almost 99% of the energy of the chemical medicine is wasted. The cause of this phenomenon is due to the instant chemical composition of the chemical tablets. At the same time, the fire-type inflator requires a large amount of chemical medicine to release a gas flow sufficient to fill the entire airbag. In order to reduce the amount of chemical tablets, therefore, some people use the medicine type) composed of a hybrid inflator, this mixture = = Erloqian heating storage gas to expand the airbag bag. Of course, /, to do: account for: large volume, heavy cylinder weight, not easy to hide in the decoration of the body! Lusheng: f Γ Ϊ is a forward-looking inflatable module, which uses a small amount of chemical bonds to burn the day ^ milk body ′ plus direct inhalation of air in the car to achieve about 30% of the inflation of the airbag. . And the efficiency of this air-inflating module to inhale the air in the car is about the same as that of the King Airbag device of ffiJL II. No matter what kind of inflation method is used, although it can reasonably operate the second degree, it still faces the same. The problem, especially this type of airbag device, is to make the Si ^ swell by the point of view so that the intake end wheel l cannot be cut, otherwise it will be read and read the pure surface _ 彡 ,, secret shadow _ hider's life security f make the working gas quickly drain from the opening at the intake end, after the driver ’s bag is filled with airbags 2 ?, or: the driver ’s frontal impact on the airbag II: and the same cannot be protected so the gas Access must be restricted. First of all, when the β is set to detonate and ignite, the outside air must be able to self-initiate, and when the gunpowder reaction inside the ^ king ’s breast pack is completed, it must be able to quotient, and § the airbag working gas ship to the outside, and Nubulin f will make y inflated, and the driver will be limited to the driver's seat: 3 笈 is why, how can the airbag device's air intake === dissipate too quickly to the outside world, it is quite similar solution

The hole is blocked. If it is, the movable flap can prevent the gas in the airbag bag from dissipating to the outside world and dissipating it to the outside world, thereby ensuring the safety of the driver. Based on the above description, I believe that the basic spirit of the present invention can be understood initially. As for the other purposes, detailed structural features and functions of the present invention, a preferred embodiment will be given below with the accompanying drawings. Say this' [Embodiment] ϋ ° According to the airbag device disclosed in the present invention that can dynamically control the state of air intake, its main purpose is to block the working gas filled in the airbag bag in a timely manner ^: To avoid the rapid loss of working gas phenomenon. Regarding the airbag capable of dynamically controlling the air intake state of the present invention, it is explained in "Fig. 1" to "Fig. 3A". The present invention is mainly composed of 'Office 10', airbag bag 20, gas generator 30, perforated air inlet plate 40, and switch. The combustion box body 10 is a hollow shell seat, which has a reaction chamber and i 丄 therein. The airbag bag 20 can be folded and stored to reduce its volume, and is sleeved on one side of the combustion chamber reaction chamber 11. The gas generator 30 is connected to the combustor body-1233409 60 ° 1130 315 ^ 2 money hole 32, and short # 31 is covered with a filter screen 33. And ^ ρρ ^^ 内 的 反应 室 11 'and is socketed to the gas generator 30, button 71. It is expected that the inner body of the listening room "Fig. 3A" 'porous air plate 4G is assembled on the other side of the combustion box / Sichuan reaction to 1, and corresponds to the airbag bag 20. The multi-hole air inlet ΓΓ ΐ ϊ is a circular air inlet hole 41 that connects the outside world with the reaction chamber 11. The air intake 1—is formed on the porous air intake plate 40 in a linear arrangement, and H i® ”/! *” Can also be formed on the porous air intake plate in a honeycomb-like manner. Mingsisi, the shape, aperture size, and arrangement of the air inlet holes 41 Various product specifications and different actual use conditions: itn ′ The present invention does not specify what it can be implemented. ^ m50 is through the fixed portion 51, and is bonded to the side of the porous inlet imf chamber 11 in a gluing manner. The moving flap 50 also includes movable flaps 52 and 53. The movable flaps 52 and 53 are opposite to the fixed portion 51. The side extends outward, in a dynamic state, and can be forced to cover the ventilation hole 41 of the full perforated air inlet plate 4G such as Kao An and enter and exit the reaction chamber 11 freely. The gas pressure of this reaction to 11 is communicated with the outside world. Therefore, it is shown that after the full gas set is activated, the gas generator 30 will ignite the gas and gas, and enter the expansion through the exhaust hole 32 of the short pipe 31. The filter 33 in the new official 31 is At this time, it plays a role in cooling the high-pressure gas generated by the gas generating agent 60, and hindering the unburned solid particles in the wide gas ejected from the short gas 31. The gas generated by the agent generating gas The exhaust hole 71 of the expansion tube 70 impacts the baffle 72 to generate a squeak effect, and forms a high-speed and low-wish airflow. If so, the reaction chamber η will generate an internal and external pressure difference with the outer 1233409 boundary, and the outside air will pass through The air inlet holes 41 of the perforated air inlet plate 40 are sucked into the reaction chamber and communicate with the gas. The gas generated by the biological agent is mixed into a working gas, and the airbag bag 20 in the folded storage state is stretched. Then, as shown in "Figure 5", the working gas instantly fills the reaction chamber ^ and the airbag bag 20, At this time, the pressure of the gas will be greater than the outside atmospheric pressure, and the working gas will inevitably have a reverse reflux phenomenon that is compressed and flushed out toward the air inlet 41. At the same time, the movable flaps 52, 53 of the deflection wing 50 will be affected by the reverse flow of the working gas, and the deformation along the flow direction of the working gas will cause deformation and cover the air inlet 41, blocking the reaction chamber 11 and the airbag. The bag 2G⑽jl is discharged to the outside as a gas, which reduces the loss of soil-made gas, so that the product can maintain a certain pressure, and the airbag bag 20 is fully deployed. It is also necessary to add that J groove 42 can be accommodated in New Test 4 (), so that the movable flaps π and M of the deflection wing 50 can be closely attached to the air intake plate 40 to prevent the escape of working gas. Improve the effect of closeness. The present ^ can be used to check the remaining state of the safe gas attachment, which through the Jit to block the working gas in a timely manner, to prevent the working gas from being too i _ points, and then let the gas limit; Wai is not intended to be used as a rough ride Minus ° & ^. 1 Tu Linfa's cross-section view of the airbag device of the Secret Secret Service-^ The picture shows another hairbag device that controls the movement of the airbag, which is controlled by a hybrid airbag. ^^ Fig. 1233409 of an airbag device capable of dynamically controlling the intake state according to the invention.
