Abstract

An apparatus for the quick inflation of an airbag has a compressed-gas tank and a propellant charge container having pyrotechnical contents which form a propellant gas upon ignition. A breakaway disk blocks passage of compressed-gas and propellant gas to the airbag and is blown off in response to the ignition of the pyrotechnical contents to unblock the passages. The breakaway disk has an opening through which the propellant gas can flow into the airbag immediately after the ignition and before the breakaway disk is blown off.
