SAFETY AIRBAG DEVICE

A safety airbag device (10), including: a safety airbag (200), having an inflated state and a stowed state; a gas generator, used to generate gas to inflate the safety airbag so that the safety airbag enters the inflated state; and a deflector (100), used to guide the gas generated by the gas generator before the gas generated by the gas generator enters the safety airbag (200). The deflector (100) includes a first cavity (101) and a second cavity (102). The first cavity (101) includes a first gas inlet (101A) and a first gas outlet (101B). The second cavity (102) includes a second gas inlet (102A) and a second gas outlet (102B). The first gas outlet (101B) and the second gas inlet (102A) are in fluid communication with each other. The gas generated by the gas generator enters the first cavity (101) by means of the first gas inlet (101A), exits the first cavity (101) by means of the first gas outlet (101B), then enters the second cavity (102) by means of the second gas inlet (102A) in fluid communication with the first gas outlet (101B), exits the second cavity (102) by means of the second gas outlet (102B), and then enters the safety airbag (200). The safety airbag device can change a flow direction of the gas generated by the gas generator and prevent an airflow from directly striking the safety airbag and causing the safety airbag to tear. Respective wall surfaces in the first cavity and the second cavity of the deflector reduce the impact of high-temperature metal particles on the safety airbag, such that the safety airbag device is highly reliable.
