The invention relates to the technical field of automotive passive safety devices, in particular to a safe airbag and a folding method of a safe airbag bag. Compared with the prior art, according to the folded safe airbag bag, in the initial expanding stage, the expanding tendency is mainly concentrated in the upward direction, and therefore the damage risks of the surface skin of an instrument board and a foaming layer are reduced; in the middle expanding stage, due to the fact that the tucked portions which are right opposite to the upper portion of a windscreen are quickly released, air in the corresponding portion in the safe airbag bag is quickly diffused towards the periphery, a low pressure portion is formed at the portion opposite to the windscreen, and therefore the risk of the windscreen damage is reduced; in the later expanding stage, due to the existence of a folding portion, the motional tendency of the safe airbag bag towards the face of a passenger is limited and guided downwards, and therefore the risk that the airbag bag flaps the face of the passenger is reduced. In addition, due to the left-side tucked portion and the right-side tucked portion, the method not only is suitable for folding the safe airbag bag designed in a two-dimensional mode, but also can flatten and fold the safe airbag bag designed in a three-dimensional mode, and therefore the adaptability is wider.
