Claims15
A device for firing a pyrotechnic propellant composition comprising:
- a firing pin drivable by a drive spring, a locking means which holds the drive spring in a prestressed rest condition and having a locking lever, which is supported at a stationary location and which is subjected to the action of a release moment due to the prestressing of the drive spring and being held in the rest position by a sensor mass, which is moved, away from the locking lever, upon excessive acceleration and by which the locking means can be released, wherein the firing pin (1) is held in a prepositioned condition with respect to a firing device of the pyrotechnic propellant composition, and a firing pin actuating means (9;
- 33) is provided which is movable with respect to the firing pin (1) and movable about a pivot axis and which is drivable by the drive spring (2;
- 34) and can be impacted against the firing pin (1).
