GRENADE FIRING MECHANISM, GRENADE AND GRENADE OPERATING METHOD

Abstract

The invention relates to a grenade firing mechanism (12) comprising a body (24) containing a firing pin (20) and a firing pin actuator mechanism (22). A safety system includes a twisting arm collar (70) and a safety lock (92). The collar can move between an unarmed position and an armed position, and the safety lock can move between a collar locking position, a collar release position, and a firing position. When the collar (70) is in the unarmed position and the safety lock (92) is in the collar locking position, actuation of the firing pin (20) is prevented, and the safety lock (92) prevents movement of the collar to the armed position. When the safety lock (92) is in the collar release position, the collar (70) can move between said unarmed and armed positions, and actuation of the firing pin is prevented.When the collar (70) is in the armed position and the safety lock (92) is in the firing position, the firing pin is activated.
