Abstract
A gas generator includes at least two functional subassemblies and at least two retention parts. The functional subassemblies each have an axis defining an axial direction and at least one outer dimension in a plane normal to the axial direction. The retention parts are each radially crimped for retaining one of the at least two functional subassemblies on the gas generator. The at least two retention parts are formed on the same part of the gas generator and the at least two functional subassemblies are positioned on the gas generator with a centre distance of axes less than or equal to 1.5 times this outer dimension and that each retention part is radially crimped over at least 90% of its periphery.
Claims15
Gas generator comprising:
- at least two functional subassemblies, each with an axis;
- at least two housings, each housing designed to receive a corresponding one of the at least two functional subassemblies;
- at least two retention parts, each retention part crimped radially for retaining a corresponding one of these at least two functional subassemblies on the gas generator,
- wherein each of the at least two housings comprises a section transversal to the axis of the functional subassembly received with a characteristic dimension such as an inside diameter, and
- wherein the at least two functional subassemblies are positioned on the gas generator with a centre distance of axes lower than or equal to 4 times one half of the sum of the characteristic dimensions and that each retention part is crimped radially on at least 90% of its periphery.
