Abstract

Die Erfindung betrifft ein Sperrelement (10) zum Verschließen eines Durchgangs umfassend einen beim Abbrand Wärme freisetzenden pyrotechnischen Satz (12) und einen thermisch expandierbaren Feststoff (14), wobei der pyrotechnische Satz (12) und der Feststoff (14) so zueinander und zum Durchgang angeordnet sind und der Feststoff (14) und der pyrotechnische Satz (12) so gewählt sind, dass der Feststoff (14) beim Abbrand des pyrotechnischen Satzes (12) expandiert und dadurch den Durchgang verschließt.

Figure imgaf001
The invention relates to a barrier element (10) for closing a passage comprising a heat-releasing pyrotechnic composition (12) and a thermally expandable solid (14), wherein the pyrotechnic composition (12) and the solid (14) are in communication with each other and for passage are arranged and the solid (14) and the pyrotechnic set (12) are selected so that the solid (14) upon combustion of the pyrotechnic composition (12) expands and thereby closes the passage.
