Abstract: The present invention relates to a safety device for a pyrotechnic assembly in a projectile, provided with an explosive charge, and comprising a mobile member actuated by a clockwork mechanism with pivoting regulator and with drive pinion and able to occupy two different positions, for the first of which the ignition of said explosive charge is prevented, while for the second of said positions the ignition of this explosive charge is possible, wherein said mobile member is housed in a recess in said projectile and encloses the clockwork mechanism, as well as a disengagement lever blocking in said first position any movement of said member with respect to the projectile but whose action may be inhibited by said clockwork mechanism and, in the first position, the axis of the pivoting regulator is merged with the axis of rotation of said projectile.

Abstract: The invention relates to a safety device for a pyrotechnic assembly in a projectile, comprising a fire-screening flap disposed between an ignition primer and explosives, said flap being mounted so as to be escapable under the action of a mechanism provided with a regulator, said regulator being mounted on said flap itself.
