  • Patent number: 7819714
    Abstract: A water activated inflator and a method of air deployment of a water activated inflatable device are provided. A gas cylinder opening device for opening a sealing mechanism of a gas cylinder is disposed at least partially within a housing and is movable between a cocked position and a fired position along a first axis having a first orientation relative to the housing. A tension mechanism provides tension acting along the first axis for moving the gas cylinder opening device from the cocked position to the fired position. A plunger is holding the gas cylinder opening mechanism in the cocked position. The plunger is disposed in the housing and movable between a first position and a second position along a second axis having a second different orientation relative to the housing. A water soluble element is holding the plunger in the first position. A first interacting surface of the gas cylinder opening device is disposed at a predetermined angle to the first axis.

  • Publication number: 20050245149
    Abstract: The present invention relates to a water activated inflator and a method of air deployment of a water activated inflatable device. A gas cylinder opening device for opening a sealing mechanism of the gas cylinder is disposed in the housing movable along a first axis having a first orientation between a cocked position and a fired position. A tension mechanism provides tension acting along the first axis for moving the gas cylinder opening device from the cocked position to the fired position. A plunger is holding the gas cylinder opening mechanism in the cocked position. The plunger is movable along a second axis having a different second orientation between a first position and a second position. A water soluble element is holding the plunger in the first position. A first interacting surface of the gas cylinder opening device is disposed at a predetermined angle to the first axis. A second interacting surface of the plunger is in contact with the first interacting surface at the predetermined angle.
