Abstract: A safety airbag, including: an air bag, having an inflated and stowed state; and a gas generator, used to inflate the air bag to the inflated state, wherein the air bag includes a body portion and a cut-out portion, the cut-out portion being formed as being cut out from the air bag, but still remaining integral with the body portion, and in the inflated state, the cut-out portion being oriented in a predetermined direction relative to the body portion via an orienting member. Using the cut-out portion to provide protection for the head of an occupant increases the utilization rate of a material for making an air bag. In addition, the height of the airbag curtain is relatively large only at the cut-out portion, and is relatively small at the remaining positions, thereby reducing the volume of the air bag.

Abstract: A safety airbag device, including a safety airbag 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, used to guide the gas generated by the gas generator before the gas generated by the gas generator enters the safety airbag. The deflector includes a first cavity and a second cavity. The first cavity includes a first gas inlet and a first gas outlet. The second cavity includes a second gas inlet and a second gas outlet. The first gas outlet and the second gas inlet are in fluid communication with each other.
