Shell assembly of air generator of safety airbag

The invention relates to the field of safety airbag assemblies, and provides a shell assembly of an air generator of a safety airbag. The shell assembly of the air generator of the safety airbag comprises a shell body and a shield nozzle, wherein the shell body is in the shape of a hollow pipe, an inlet is formed in one end of the shell body, and the air generator of the safety airbag is arrangedin the shell body through the inlet; and the shield nozzle is connected to the other end of the shell body, and air jet holes connected with an airbag are formed in the shield nozzle. Assembly holes used for assembling the air generator of the safety airbag are formed in the shell body. The shell assembly is used for shielding heat generated when the air generator of the safety airbag works, the air generator can be directly installed, and an air generator installation part formed by a plurality of layers of coating cloth no longer needs to be sewn on the airbag in a target mode, so that the airbag is easier to fold a
