Safety arming system for an explosive charge

A safety arming system for an explosive charge, comprising:

• a sleeve that carries a detonator for actuating said explosive charge and which, in a cylinder, is able to move between a fixed safety position in which the detonator is away from said explosive charge, and a fixed arming position in which said detonator is aligned with said explosive charge;
• an arming actuator for moving said sleeve from said fixed safety position to said fixed arming position;
• a disarming actuator arranged opposite said arming actuator with respect to said cylinder, able to return said sleeve from said fixed arming position to said fixed safety position;
• and
• a jacket inside said cylinder, inside which said sleeve is able to move, under the action of said arming actuator, from said fixed safety position to said fixed arming position until it is secured to said jacket, in said fixed arming position, by virtue of spontaneous securing means, and which is able, under the action of said disarming actuator, to slide in said cylinder in order to return said sleeve, which has thus become spontaneously fixed thereto, from said fixed arming position to said fixed safety position.

The system according to claim 1, further comprising:

• a first breakable connection, between said sleeve and said jacket, able to be broken by the action of said arming actuator;
• a second breakable connection, between said jacket and said cylinder, able to be broken by the action of said disarming actuator;
• and
• a stop system able to prevent said jacket from moving to the arming position under the action of the arming actuator.
