Safety device for use in igniter for preventing unintentional activation of main charge of artillery projectile, has retaining element holding safety element during movement of safety element out of catching chamber

摘要

The device (6) has an ignition blocker (16) i.e. mechanical barrier, for blocking ignition of an igniter. A safety element (20) e.g. bolt, blocks a releasing movement of the ignition blocker. A catching chamber (24) is arranged so that a part of the safety element is moved in the catching chamber during a releasing movement of the safety element. A retaining element (34) i.e. planar metallic disk, holds the safety element during a movement of the safety element out of the catching chamber. A pyrotechnic charge (22) is prepared for producing the releasing movement of the safety element.
