Abstract

Die Erfindung geht aus von einer Sicherungseinrichtung (2, 74) für einen Zünder, umfassend eine Zündkette (8) mit einem Zündmittel (10) und einer Barriere (16, 76), die in ihrer Sicherstellung von einem ersten Sicherungsmittel (24) und einem vom ersten unabhängigen zweiten Sicherungsmittel (26) verriegelt ist, die zu einer Entriegelaktion aufgrund zwei voneinander unabhängiger physikalischer Entsicherungspararneter vorgesehen sindThe invention relates to a safety device (2, 74) for an igniter, comprising a detonating chain (8) with an ignition means (10) and a barrier (16, 76) secured by a first securing means (24) and a safety device is locked by the first independent second securing means (26), which are provided for an unlocking action due to two independent physical Entsicherungspararneter

Es wird vorgeschlagen, dass die Zündkette (8) ein zweites Zündmittel (14) umfasst und die Barriere (16, 76) in einer Sicherstellung einen Zwischenraum (62) zwischen den beiden Zündmittein (10, 14) blockiert und durch eine den Zwischenraum (62) freigebende Freigabebewegung in eine Scharfstellung bringbar ist. Es kann eine kompakte und sehr zuverlässige Sicherungseinrichtung (2, 74) erreicht werden.

It is proposed that the firing chain (8) comprises a second firing means (14) and the barrier (16, 76) in a safeguard blocks a gap (62) between the two firing centers (10, 14) and through a gap (62 ) releasing release movement in a focus can be brought. It can be a compact and very reliable security device (2, 74) can be achieved.
