" air bag on rolling direction detonates " in Fig. 4 or Fig. 5 can also be changed to " all by the implementation strategy of rolling operating condition
Air bag detonation " (once rolling, which occurs, reaches threshold value, after all air bags detonation, the judgement for operating condition of rolling and execute program
It can stop, being rejudged without returning).It can be executed to after the judgement of operating condition to each airbag inflated and row by sensor
The independent control of gas.Judgement and execution to two kinds of operating conditions of collision and rolling are also independent.Drain tap is if necessary to be beaten
It opens, the energization moment of actuator can be delayed by, and the time of delay meets drain tap while air bag is full of and opens.
When single collision operating condition, system can be quick-fried by the gas generator point of the airbag inflated on corresponding direction, prolongs
The pyrotechnics device point quick-fried (or magnet suction device energization) of the drain tap of the air bag is exhausted, occupant after slow a period of time
Gas can be extruded and be discharged to the external world after touching air bag, since the time that air-bag deployment is full of faster (was unfolded
There is no discharge loss when journey), need the capacity of gas generator smaller, and the safety of exhaust structure (i.e. drain tap) arrangement
On airbag housing, position is fixed and in inside, will not be as the gas vent of existing air bag is on airbag, easily by environment part
It squeezes, block and influence exhaust rate, protecting effect is unstable.
When single rolling operating condition, the air bag on the unfolded rolling corresponding direction of system (can also be by interior all peaces
The gas generator point of full air bag inflation is quick-fried to be used for airbag deployment), since air bag is sealing state, when can provide long
Between lasting rolling protection, and provide the protection of more direction compared with the prior art, be also not only limited to the protection on head.
Continuous duty: if after first colliding and rolled, system can be automatically by other substitutes that do not detonate
The gas generator point of capsule is quick-fried (air bag to have detonated when collision is in rolling just without protective capability), if rolling it
Afterwards again collide, then system can the air bag point on corresponding direction is quick-fried (such as it up till now air bag had detonated, then neglect
Slightly), the larger kinetic energy of occupant is absorbed when opening by the drain tap of corresponding air bag after delay and be used to collide operating condition, to realize
Safeguard protection to occupant.
The present invention is convenient and practical, easy to operate.Beating automatically for bleeder port is controlled by the pressure of gas in airbag itself
Push And Release closes, and on the one hand can be lost heart less when airbag deployment is inflated, reduce gas consumption；On the other hand more importantly, can
Make to retain certain residual gas pressure in air bag, extends the buffer function time of air bag, pressure when avoiding high velocity impact in air bag
It quickly lets out to the greatest extent and interior driver (or occupant) is caused finally to strike on the hard object such as steering wheel (or instrument board) and sustain a severe injury.
