Abstract
Pyrotechnic signaling means () are ignited manually by pulling on a pulling member (). In known pyrotechnic signaling means (), the pulling member () has a short cable which is knotted to an operating means (). A knot such as this can be produced only manually, thus making the production of pyrotechnic signaling means () quite complex. In addition, an ignition device () for known pyrotechnic signaling means () has a hole through it for a firing bolt () which is connected to the pulling member (). This allows moisture to enter the pyrotechnic signaling means () through the ignition device (). The pyrotechnic signaling means () according to the invention provides for the pulling member () to be formed from flexible strip-like sections (), which are connected by film hinges () and can be collapsed, saving space, when not in use. The sections () can be integrally connected to an operating means (), such that the entire pulling member () can be formed integrally from plastic and manual fitting of the individual components of the pulling member () is superfluous. The invention also provides for the ignition device () to be sealed by a coupling device () of the pulling member () until the pyrotechnic signaling means () are activated. This means that no moisture can pass through the ignition device () before the pyrotechnic signaling means () are activated.
