Abstract:
1. A water activated inflator comprising: a gas cylinder opening device for opening a sealing mechanism of a gas cylinder, the gas cylinder opening device being disposed at least partially within a housing and being movable between a cocked position and a fired position along a first axis having a first orientation relative to the housing; a tension mechanism in mechanical communication with the housing and the gas cylinder opening device for providing a force F acting along the first axis for moving the gas cylinder opening device from the cocked position to the fired position; a plunger for holding the gas cylinder opening device in the cocked position, the plunger being 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 for holding the plunger in the first position through mechanical communication along the second axis with the plunger and the housing; a conduit for providing water to the water soluble element; a first interacting element in mechanical communication with the gas cylinder opening device and having a first interacting surface, wherein a portion of the first interacting surface is disposed at a predetermined angle other than 90 or 180 degrees to the first axis; and, a second interacting element in mechanical communication with the plunger and having a second interacting surface for interacting with the first interacting surface at the predetermined angle, such that a component F wherein the predetermined angle is determined such that along the second axis a component F
