PCT No. PCT/FR94/01356 Sec. 371 Date Jul. 10, 1995 Sec. 102(e) Date Jul. 10, 1995 PCT Filed Nov. 22, 1994 PCT Pub. No. WO95/16891 PCT Pub. Date Jun. 22, 1995A safety device to lock a firing pin of a spin-stabilized projectile fuse includes a flexible strip and a spiral spring. The flexible strip is disposed around the firing pin and has a first end, a second end and a length. The flexible strip is made of an elastic material. The spiral spring is windable around the flexible strip in a safe position and is disposed to unwind under centrifugal force to a firing position. The spiral spring is made of a spring strip that is wound around itself. When the spiral spring unwinds, the flexible strip unwinds within the spiral spring without exerting an elastic return force toward the firing pin. The length of the flexible strip is dimensioned such that the first end is offset in a circumferential direction relative to the second end by an offset amount when the flexible strip presses against the spiral spring in the firing position. As a result, the spin-stabilized projectile fuse functions reliably. |
