Abstract

An automobile airbag shell structure is composed of a metal framework, a fabric tape net, a bracket and a U-shaped steel wire, wherein the fabric tape net is formed by weaving fabric tapes. The fabric tape tail end located on the inner side of the fabric tape net is provided with circular collars. The fabric tape tail end located on the outer side of the fabric tape net is provided with angular hanging rings. The U-shaped steel wire penetrates through all the collars on the inner side of the fabric tape net and then is fixed on the inner side of the bracket. The periphery of the metal framework is provided with hooks corresponding to all the fabric tapes. The hanging rings on the outer side of the fabric tape net penetrate through the metal framework and then are hung on the hooks on the periphery of the metal framework. The netty structure is formed by sewing the fabric tapes, one end of the netty structure is hung on the metal framework, the other end of the netty structure is fixed on the bracket through the U-shaped steel wire, and therefore a hollow netty container structure is formed. The automobile airbag shell structure is high in rigidity, low in cost and light in weight, thereby being in accordance with the light weight development trend of automobiles.

Description

technical field [0001] The invention relates to an automobile safety air bag shell structure. Background technique [0002] In the airbag structure, the shell is used as a container assembled after the bag body of the airbag is folded. Traditional airbag shells are generally welded or stamped from metal sheets, plastic shells are also formed by injection molding, and fabrics are sewn into cloth bags to wrap the airbags. [0003] The shell structure of metal or plastic is complex in structure and heavy in weight, while the cloth bag structure formed of textile will cause large deformation due to its flexibility when the airbag is detonated, and requires higher strength for the surrounding parts of the airbag. Contents of the invention [0004] The object of the present invention is to overcome the above-mentioned defects and provide an automobile airbag shell structure with good rigidity, low cost and light weight, which is in line with the development trend of automobile ...
