Abstract

The invention relates to an igniter with a delay time (Vz) that can be set. The delay time (Vz) can be fixedly defined, or individually and situation-dependently set on-site. In particular, the invention relates to a delay time that can be set for a stun grenade, a hand grenade etc., with options for the individual setting and situation-dependent or situation-contingent customisation of the delay time (Vz), and consequently of the effect of the active compositions in-situ. In order to achieve individual setting options, the invention proposes that at least two different delay times (Vz) can be set. To this end, the igniter has, in a delay section, preferably in the fuse head, a relief bore that can be closed or opened.

First claim

What is claimed is:

1. An igniter with an adjustable delay time, wherein a relief bore is provided in a delay line of a delay charge and wherein the relief bore is configured to be opened or closed by a pin.

2. The igniter as claimed in claim 1 , wherein the pin includes a split pin.

3. The igniter as claimed in claim 1 , wherein the pin is configured to be pulled, pressed, or twisted.

4. The igniter as claimed in claim 1 , wherein the delay time is adjustable between a first set delay time and a second set delay time.

5. The igniter as claimed in claim 4 , wherein the delay time is adjustable between at least one of the following: 0.5 seconds and 1.0 second, 1 second and 1.5 seconds, and 1.5 seconds and 2 seconds.

6. An irritation body comprising the igniter as claimed in claim 1 .

7. The irritation body as claimed in claim 6 , further comprising an igniter head, wherein the relief bore is inserted in the igniter head.

8. The irritation body as claimed in claim 7 , further comprising a housing, wherein an opening of the relief bore is realized by a slight movement of the igniter head upwards relative to the housing.

9. The irritation body as claimed in claim 6 , further comprising a safety catch configured to prevent manipulation of the adjustable delay time and the pin.

10. A hand grenade comprising the igniter as claimed in claim 1 .

11. The hand grenade as claimed in claim 10 , further comprising an igniter head, wherein the relief bore is inserted in the igniter head.
