Abstract

A firing pin assembly for mechanically igniting a warhead detonator of a projectile by being accelerated in a forward direction by inertia upon impact, includes a firing pin having a rearward firing pin part and a frontal firing pin part arranged in series with the rearward firing pin part as viewed in the forward direction. The assembly further has a firing pin spring urging the firing pin in a direction opposite to the forward direction, and a mechanical device positioned between the rearward firing pin part and the frontal firing pin part. The mechanical device includes a transmission arrangement for transmitting a forward motion of the rearward firing pin part to the frontal firing pin part with a stepped up transmission ratio whereby a forward motion of the rearward firing pin part through a first distance results in a forward motion of the frontal firing pin part, against the force of the firing pin spring, through a second distance which is greater than the first distance.

A firing pin assembly for mechanically igniting a warhead detonator of a projectile by being accelerated in a forward direction by inertia upon impact;

comprising
(a) a firing pin including
(1) a rearward firing pin part;
and
(2) a frontal firing pin part arranged in series with said rearward firing pin part as viewed in said forward direction;
(b) a firing pin spring urging said firing pin in a direction opposite to said forward direction;
and
(c) a mechanical device positioned between said rearward firing pin part and said frontal firing pin part and including
(1) means for spacing said rearward firing pin part from said frontal firing pin part;
and
(2) transmission means for transmitting a forward motion of said rearward firing pin part to said frontal firing pin part with a stepped up transmission ratio whereby a forward motion of said rearward firing pin part through a first distance results in a forward motion of said frontal firing pin part through a second distance against a force of said firing pin spring;
said second distance being greater than said first distance.
