1. An apparatus for inflating an inflatable container in which a delay is provided and wherein a gas propellant is activated without direct use of an electric signal, comprising:

  • first means for containing gas and having a wall;

    electro-explosive device means for creating a path for gas from said first means to the inflatable container, wherein said electro-explosive device means is electrically activated;

    propellant means positioned within said first means;

    pressure sensing means operatively connected to said first means for monitoring a differential pressure between a first pressure related to the pressure of the gas in said first means and a reference pressure, wherein said reference pressure exceeds said first pressure during the dynamic state and wherein the gas creating said reference pressure does not provide a substantial portion of the gas used to inflate the inflatable container; and

    second means for controlling activation of said propellant means, wherein said second means responds to movement of at least a portion of said pressure sensing means away from said reference pressure to activate said propellant means after a delay without electrical activation thereof, thereby increasing the gas flow rate provided to the inflatable container.
