A self-contained inflatable passive restraint system for passenger vehicles includes a support housing structure that provides support for the inflatable cushion or crash bag which is folded thereon when in an undeployed state and contains all of the components, including collision responsive sensor
A self-contained inflatable passive restraint system for passenger vehicles includes a support housing structure that provides support for the inflatable cushion or crash bag which is folded thereon when in an undeployed state and contains all of the components, including collision responsive sensor means, required for inflation of the crash bag responsively to the occurrence of a collision. A plastic cover over the support housing structure and crash bag provides an environmental seal therefor.

1. Structure for the inflation of inflatable protective bags for safety systems for vehicles, comprising, in combination: a cup-shaped member having a substantially flat base and including an annular wall attached to said base, being generally perpendicular thereto, and forming a cylindrical open
1. Structure for the inflation of inflatable protective bags for safety systems for vehicles, comprising, in combination: a cup-shaped member having a substantially flat base and including an annular wall attached to said base, being generally perpendicular thereto, and forming a cylindrical opening therein, said wall having a screw thread formed on the inner surface thereof remote from said base and having at least one channel formed therein extending for substantially the full length of said wall in a direction generally perpendicular to said base, passageway means in said base providing communication between said channel and said cylindrical opening, stab primer and booster charge means located in said channel adjacent said base, inertial firing pin means located in said channel separated from said percussion and booster charge means, over-center spring means normally holding said firing pin means out of contact with said percussion and booster charge means but operative, when subjected to deceleration in the direction of said base accompanying a crash, to move over center thereby to effect actuation of said firing pin means toward and into contact with said percussion and booster charge means, cover means for covering the end of said annular wall remote from said base including a first substantially flat plate having an imperforate circumferential edge portion of size sufficient at least to close said channel and having a central portion with peforations therein, said central portion enclosing said cylindrical opening of said wall means to form a reaction chamber and to retain combustible gas generant means therein, said cover means further including first and second cylindrical portions extending substantially perpendicularly in opposite directions from said first plate with said first one of said cylindrical portions extending into said cylindrical opening of said wall means, said first one of said cylindrical portions having external screw threads thereon adapted for mating engagement with the screw threads formed on the inner surface of said opening, and said second cylindrical portion having perforations therein, a second substantially flat plate covering the end of said second cylindrical portion remote from said first plate, said second plate being imperforate and having a circumferential flange extending beyond the perimeter of said second portion to define, with said second cylindrical portion and said first plate, an annular space, heat sink screen means provided in said annular space, and crash bag means having an opening with said opening attached in gas tight relationship with said base, with said cup-shaped member, cover means and said second flat plate extending therein, said perforations in said first plate and in said second cylindrical portion providing openings for the outlet flow of generated gases through said heat sink screen means into said crash bag means. 2. Structure as defined in claim 1 wherein said base of said cup-shaped member is circular and includes a flange portion and further including a retaining ring, and wherein said opening of said crash bag means is retained in gas tight relation between said retaining ring and said flange portion of said base. 3. Structure as defined in claim 1 wherein said crash bag means when in undeployed state is folded on said cup-shaped member, cover means and second plate, and further including a plastic cover over said structure including said crash bag means, said plastic cover being connected in gas tight relation to said base of said cup-shaped member. 4. Structure as defined in claim 3 wherein said plastic cover is adhesively sealed to said base thereby to provide an environmental seal therefor.
