Abstract
The firing mechanism for a pyrotechnical gas generator in the tightening means of a safety belt restraining system includes a pivotally mounted vehicle-sensitive inertia mass, a spring-loaded pivotally mounted strike piece, a firing pin which is arranged with its free end lying opposite the impact fuse of the gas generator and with its other end lying opposite the strike piece, and a roller blocking mechanism which in the readiness state holds the strike piece at a distance from the opposite end of the firing pin and on vehicle-sensitive pivoting of the inertia mass after over-coming an inhibition threshold releases the strike piece which then under the action of the spring biasing is driven to the oppositely disposed end of the firing pin, strikes the latter and via the firing pin effects firing of the gas generator.
