Airbag pyrotechnic gas generators occupy a key position in the vehicle passive safety system with all the importance of the other components. Despite the abundance of various types of the airbags, single-stage pyrotechnic gas generators for the driver and passenger airbags are most interesting to the domestic vehicles manufacturers due to the budget cars leading positions in the domestic market. For proprietary design, development and production of the airbag gas generators, it is necessary to combine efforts of specialists in the chemical industry and in general engineering. At the same time, it should not be forgotten that production of the pyrotechnic airbag gas generators is subject to strict national and international regulation. Therefore, comprehensive system analysis of the pyrotechnic gas generators design by foreign manufactures used in the modern vehicles becomes important and necessary to form scientific and technical base for design and development of the proprietary commercial gas generators and localizing the full cycle of mass production of such devices in the territory of the Russian Federation. General classification of the airbag gas generators is provided, key features of the product design and production technologies for the main components of the dome-shaped solid fuel gas generator with a single-stage airbag response are considered, and technological schemes of the assembly processes and basic assembly operations are analyzed using the example of gas generators of different generations. Results of the study are of interest to the automotive industry specialists
