The invention relates to the technical field of automotive passive safety devices, in particular to a knitting molding gasbag comprising a gasbag body. The gasbag body is formed by warp yarn knitting integrally, the section of the yarns is in a special shape, the special-shaped sections of two adjacent yarns are fitted tightly, an outer cavity fixing bag is arranged outside the gasbag body, and warp and weft directional stripes are arranged on the outer cavity fixing bag in the warp and weft directions. Compared with the prior art, the knitting molding gasbag has the advantages that the one-step forming gasbag structure by warp yarn knitting is designed, the manufacture process is simpler, and the production cost is reduced; the section of the yarn is in the special shape, the tightness of the yarns is improved, the gas leakage is controlled after the gasbag is inflated, the outer cavity fixing bag is arranged outside the gasbag body to control the shape of the gasbag body and limit the drawing degree of the fabric of the gasbag body during operation, and the passenger restraint performance can be guaranteed accordingly.
