The invention relates to the technical field of automobile safety air bags, in particular to a gas generator and an automobile. The gas generator comprises a main body, an elastic body, a gas generating unit and an annular filtering unit; the body is provided with an inner cavity. The elastic body is contained in the inner cavity and divides the inner cavity into a filter cavity and a combustion cavity, and the filter cavity is located above the combustion cavity; the gas production unit is accommodated in the combustion cavity; the annular filter unit is contained in the filter cavity, the annular middle of the annular filter unit communicates with the combustion cavity, and a hole opening is formed in the side wall, right opposite to the periphery of the annular filter unit, of the body. The gas generator is simple in structure, convenient to assemble and capable of simplifying the assembling steps and improving the assembling efficiency, so that the assembling quality can be improved, and abnormal sound can be avoided.

    本发明涉及汽车安全气囊技术领域,具体而言,涉及一种气体发生器和汽车。气体发生器包括主体、弹性体、产气单元以及环形过滤单元;主体设置有内腔;弹性体容置于内腔,且将内腔分隔为过滤腔以及燃烧腔,过滤腔位于燃烧腔的上方;产气单元容置于燃烧腔;环形过滤单元容置于过滤腔内,且环形过滤单元的环形中部与燃烧腔连通,主体正对于环形过滤单元外周的侧壁开设有孔口。该气体发生器结构简单,装配方便,能够简化装配的步骤,提高装配效率,从而能够提高装配质量,并且能够避免出现异响。
