When the automobile has a front collision accident, the gas generator in the safety airbag device quickly provides high-pressure gas, the bag is quickly flicked, the front seat comprises a driving seat and a passenger seat, and the forward kinetic energy of the human body is absorbed, so that the passenger is protected.
Since the automobile runs at a high speed, when the automobile is in a collision accident, the time of passenger injury caused by the motion inertia of the automobile is measured in tens of milliseconds, which puts high technical requirements on an air bag device serving as an automobile collision safety protection device. However, the current automobile airbag device has several problems as follows: first, when the head of the passenger hits the airbag, the head of the passenger often slips off the airbag due to the body inertia after the collision of the vehicle, the bounce of the airbag, and the difference in relative displacement between the body and the vehicle caused by the collision, which impairs the protection function of the airbag device. Secondly, the prior airbag device for front protection has one or more air release holes, when the gas flows into the airbag from the gas generator, the gas continuously flows out from the air release holes of the airbag, and the problem of low gas utilization rate exists. Thirdly, when a collision accident occurs in a high-speed running automobile, the inertia of a human body and an automobile body is large, the human body and objects cannot stop moving immediately after the first wave impact, and the collision of a second wave can often occur, but the conventional airbag device for front protection can only protect the first wave collision and basically has no protection effect on the second wave collision. Fourth, the automobile body deformation characteristic is also different when different automobile models lead to the car collision because of body structure's difference, and its best matching's air bag parameter requirement is also different, but present air bag device is because there is the gas in the design from the air bag hole uncontrolled gas leakage phenomenon that loses heart, so hardly do the use of best matching's air bag parameter meticulously, influence the protection effect.
Therefore, it is important to develop a new high-efficiency airbag device to solve the above problems.
