Abstract:
1. An igniter for a projectile to be fired from a barrel with angular momentum, comprising an ignition chain triggering an active effect, a safety device which, in a first position, interrupts the ignition chain and, upon firing of the projectile, passes over to a second position releasing the ignition chain due to an initial acceleration and angular momemtum of the projectile, wherein the safety device comprises a disk-shaped element having a central portion and a boundary portion surrounding the central portion; wherein only the central portion of the disk-shaped element interrupts the ignition chain; wherein the central portion of the disk-shaped element, but not the boundary portion, is supported and kept in place by a holding device; wherein the central portion and the boundary portion are connected with each other through a rated breaking point or line that tears upon the initial acceleration of the projectile; and wherein a collecting space is provided around the holding device which receives the boundary portion that is separated from the central portion upon the initial acceleration of the projectile and the central portion that is subsequently removed from the ignition chain by rotation of the projectile.
