  • Patent number: 5941752
    Abstract: A self-inflating enclosure providing a fracturable first envelope; a first reactive component contained within the first envelope, the first reactive component being fluid; a second envelope having at least one self-sealing aperture therethrough, the first envelope being contained within the second envelope, the first envelope being in fluid communication with the second envelope upon fracturing of the first envelope, the first reactive component being dischargeable into the second envelope upon fracturing of the first envelope; a second reactive component contained within the second envelope, the second reactive component being reactable with the first reactive component to generate a gas; and, a third envelope, the second envelope being contained within the third envelope, the third envelope being in gas communication with the said second envelope only during the second envelope having a predetermined internal pressure, the gas being dischargeable into the third envelope only upon the second envelope having

  • Patent number: 4929214
    Abstract: The invention provides novel inflatable enclosure means including an inflatable outer envelope surrounding novel means for generating a gas to inflate the outer envelope. The novel gas generating means includes a fracturable first envelope, which contains a first reactive component of a multi-component gas generating chemical system, and a second envelope in fluid-communication with the first envelope upon fracture of the first envelope and containing a second reactive component of the gas generating chemical system. The first envelope is fractured to release the reactive component contained therein, so that it mixes with the other reactive component contained in the second envelope, thereby generating an inflating gas.
