Abstract

The invention relates to a safety airbag, comprising: an airbag with a side air curtain and a front airbag; an air guide bag for introducing gas generated by a gas generator into the air bag; and an anti-backflow component connected to the air guide bag, The anti-backflow component prevents the gas in the front airbags from flowing back to the side air curtains when the front airbags are squeezed. The airbag can protect the occupant's head and effectively reduce the head and neck injuries of the occupant.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a safety airbag. Background technique [0002] Airbags are used to provide effective crash protection for occupants in the event of a car collision. Generally, the airbag device that protects the occupant's head in a side collision adopts a side air curtain, which can protect multiple rows of occupants at the same time. [0003] Traditional side air curtains are installed on the side wall sheet metal, generally extending from the front pillar to the rear pillar of the car, located above the pillar trim, partially hidden by the edge of the roof, and not visible from the inside of the car. When the vehicle is hit by the side, after the ECU (Electronic Control Unit, electronic control unit) sends out an ignition signal, the side safety air curtain is inflated rapidly, the air bag pushes the roof, spreads downward across the interior, covers the side window area, and is located i...
