Arming safety device for ammunition such as a rifle grenade or an anti-tank rocket

摘要

The invention relates to an arming safety device for ammunition, such as a rifle grenade or an anti-tank rocket, of the type comprising a piezoelectric generator 9 arranged to charge a capacitor when pressure is applied to it, and a rotor 33 which, in a first position, keeps an element 34 of the pyrotechnic chain away from said pyrotechnic chain and, in a second position, keeps said element of the pyrotechnic chain aligned with the pyrotechnic chain. It comprises driving means to bring the rotor virtually instantaneously from its first position to its second position, and a delay mechanism 23 arranged so as to keep said driving means inert during a first operating sequence commencing at the firing of the shot and of predetermined duration, and to release these driving means at the end of said first sequence.
