摘要： An airbag and an airbag assembly comprising a gas generator and an airbag. An airbag (10, 20, 30, 40, 50, 100) comprises a deployed state and a collapsed state, the airbag being capable of providing protection for occupants between the occupants and the inside of a vehicle when the airbag is inflated and expanded to be in the deployed state, and being capable of being accommodated in a predetermined space in the vehicle when in the collapsed state. The airbag (10, 20, 30, 40, 50, 100) comprises at least a first end (11, 21, 51) and a second end (12), the first end (11, 21, 51) being a free end of the airbag, and the second end (12) being used for fixing the airbag to a mounting position. The airbag (10, 20, 30, 40, 50, 100) comprises a folding portion (13, 23, 33, 43, 53) and a rolling portion (14, 24, 34) when in the collapsed state, wherein the folding portion (13, 23, 33, 43, 53) is formed by folding one part of the airbag in an "N" shape; the rolling portion (14, 24, 34) surrounds a periphery of the folding portion (13, 23, 33, 43, 53), so that the folding portion (13, 23, 33, 43, 53) is completely surrounded by an inner side of the rolling portion (14, 24, 34); and the first end (11, 21, 51) is also positioned at the inner side of the rolling portion (14, 24, 34). The airbag assembly comprises a gas generator and the airbag described above. The airbag with the above structure has the advantages of easy to manufacure, needing only to take a small space of a vehicle, and a low mounting and fixing cost.
