Abstract

An airbag structure device, comprising a press cover (1), an airbag (2), and a base (3); the press cover (1) is mounted on the base (3); a collar of the mouth of the airbag (2) is clamped between the press cover (1) and the base (3); at the portion of the collar of the mouth where it is clamped, the press cover (1) presses against the outer surface of the collar of the mouth, and the base (3) presses against the inner surface of the collar of the mouth. By latching the press cover (1) on the base (3) in a snap-fit manner, a pressing and sealing connection is implemented at the collar of the mouth of the airbag; a reinforcing rib (101) increases a pressing force, implementing locking and sealing at a time. A sealing strip (201) extends out from the airbag (2), and an injection-molded needle (4) is integrally formed with the base (3), reducing the number of components and wirings. By increasing the thickness of some of the walls of the airbag (2), the deformation of the airbag (2) can be restricted.
