  • Publication number: 20090102080
    Abstract: There is provided a tubular molded article of a gas generating agent consisting of a non-azide-based composition. Both ends of the molded article are squashed. A gas-generating-agent producing process is to obtain a gas generating agent which is molded into the form of a tube both ends of which are squashed in such a way that the tubular molded article of the gas generating agent being in a wetted state is passed through a gap between a pair of molding gears that are rotatable so that each convex tooth of one of the molding gears can face that of the other molding gear, thereafter the molded article is squashed with the convex teeth at predetermined intervals, thereafter the molded article is cut off at the squashed concave parts in such a way as to be folded, and the resultant cut pieces are dried.

    Abstract: There is provided a tubular molded article of a gas generating agent consisting of a non-azide-based composition. Both ends of the molded article are squashed. A gas-generating-agent producing process is to obtain a gas generating agent which is molded into the form of a tube both ends of which are squashed in such a way that the tubular molded article of the gas generating agent being in a wetted state is passed through a gap between a pair of molding gears that are rotatable so that each convex tooth of one of the molding gears can face that of the other molding gear, thereafter the molded article is squashed with the convex teeth at predetermined intervals, thereafter the molded article is cut off at the squashed concave parts in such a way as to be folded, and the resultant cut pieces are dried.

  • Publication number: 20050225064
    Abstract: A gas generator comprising a housing (3) made of metal and having an initiator shell (1) and a closure shell (2), (a) combustion chamber(s) (5, 5a, 5b) formed in the housing (3) and packed with gas generant (4) that generates high temperature gas by burning, (a) filter member(s) (6, 6a, 6b) arranged around the combustion chamber(s) (5, 5a, 5b), (an) igniter device(s) (7, 7a, 7b) put in the housing (3) for igniting and burning the gas generant (4) in the combustion chamber(s) (5, 5a, 5b), and a plurality of gas discharge holes (8) formed at the housing (3), for discharging gas generated in the combustion chamber(s) (5, 5a, 5b), wherein either or both of the initiator shell (1) and the closure shell (2) forming the housing (3) has a head portion (14, 10) of a semispherical form or an oval semispherical form and a cylindrical portion (13, 9) of a diameter (D) formed continuously from the head portion (14, 10), and wherein a ratio H/D between the diameter D of the cylindrical portion (13, 9) and a distance H betw
