(4) Joint locking organization:
Lock the locking clasp of joint to fasten the connection of joint.
2. When the automobile front face is impacted, and generated force is bigger than the standard pre-set,
airbag will work automatically. The sensor in safety airbag controller will feel the impact, at the same
time, it will judge the generation of impact by inner arithmetic to make ignition electric current. Electric
current will flow in gas generator to make explosive function, then two gas generators in airbag at the
side of driver and passenger will make gas to increase quickly inner pressure of airbag and rush out
the trim cover of steering wheel and instrument panel. After airbag charging is closed, the gas ejects
from the gas outlet at the side or at the back of airbag.
