What is?
Additional variable vent disposed on the back surface of the airbag, and the cover plate and the restraint system by a flexible cord consisting of flexible connection control. When the passenger airbag pressed, the variable vent opening of the airbag quickly discouraged. Reduce the damage due to passenger air bag inflates caused.

You know what?
This technique may be applied in a single stage airbag.
two airbag smaller compared with the structure simpler, less costly.

Principle
provided additional back surface of the airbag variable vent, a new cover plate covers the flexible vent hole, the flexible cover is controlled by a flexible connection cord is connected to the interior of the restraint system. The stage when the airbag is inflated, by an internal restraint system flexible connection cord tightly cover the flexible plate at a variable vent to prevent the deflated balloon in the inflated phase advance. When the passenger airbag squeeze due to the inertia of the traditional balloon deflated system to work, while internal restraint system burdens when squeezed soft relaxation, open the vent cap flexibility, the balloon deflated quickly, reduce the damage due to passenger air bag inflates caused.

two airbags
a collision when, or if the occupant sitting relatively thin body near the steering wheel, the system will issue an ignition command to the ignition device of the airbag is not fully inflated. It reduces the chances of small stature occupant injury. If the occupants of the stature and posture can withstand the greatest degree of protection, then the system will trigger two ignition devices to complete the whole inflatable balloon.
