Abstract
A clamping ring is used to mount an air bag gas generator cartridge on a support plate. A tensioning ear is formed in the clamping ring. Further, a wave is formed in the ring to increase the holding force between the ring and the cartridge. The wave consists of two convex arches projecting outward from the ring and an inward convex arch therebetween, the apex of the inward arch being at least tangential to the circle defined by the remaining portions of the ring in the initial condition of the ring. This type of clamping ring mounting is capable of withstanding torques between the cartridge and the support plate of well above 10 Nm.
