Automobile safety air bag filter with two annular convex ends

The utility model provides an automobile safety air bag filter with two annular convex ends, which comprises a filter body, the inner side of the end surface of a hollow annular convex body is a concave surface, and the outer side of the end surface of the hollow annular convex body is a convex surface; the filter body is formed by overlapping a plurality of layers of steel screens, and mesh outward-turning bulges are arranged at the peripheries of meshes of the steel screens; hole sites of the multiple layers of steel screens are staggered with hole sites of the outermost layer and the innermost layer, and the air bag has the advantages of being firmer in the whole, higher in impact resistance, higher in gas flow rate and more effective in detention of explosion residues, so that the inflation speed of the air bag is increased, and harm caused by the explosion residues is further reduced. 本实用新型提供了一种两端环凸的汽车安全气囊过滤器，包括过滤器本体，所述空心环凸体的端面内侧为凹形面，所述空心环凸体的端面外侧为凸形面；所述过滤器本体由多层钢板网叠加组成，所述钢板网的网孔周边开设有网孔外翻凸起；所述多层钢板网中各层钢板网的孔位
