Patent ID: 8065960

Claim:
A hand grenade with an active body containing an active charge, and with an ignition device that acts on a detonator to ignite the active charge, wherein: (a) the ignition device is an electronic ignition system comprising an ignition trigger and a fuze; (b) the fuze includes a first ignition circuit arranged in the active body and the ignition trigger is arranged in a control part that can be removed from the active body before the hand grenade is thrown and that can remain with the user of the hand grenade; (c) the ignition trigger includes a transmitting device that operates by wireless, and the fuze includes a receiving device that interacts with the transmitting device, so that after the hand grenade has been thrown into a target area, a carrier signal coded with an ignition code is emitted by the transmitting device by means of an ignition trigger element of the ignition trigger, wherein the carrier signal is received by the receiving device of the fuze, decoded, and utilized to activate the detonator of the hand grenade, wherein the ignition device includes a code generator that, with the aid of a random generator, produces an ignition code immediately before or at detaching of the control part, wherein the ignition code is stored both in a code memory of the ignition trigger and in a code memory of the fuze and, upon activation of the transmitting device, serves to code the carrier signal produced by the transmitting device.
