Abstract
An apparatus for inflating an air bag of a protection device. The apparatus includes a canister including a first compartment and a second compartment. The first compartment is adapted to contain a compressed gas. A seal is between the first compartment and the second compartment which is adapted to seal the compressed gas inside the first compartment. The second compartment includes a two-step mechanism configured to break the seal to cause thereby an initial gas flow from the first compartment into the second compartment. The initial gas flow causes a wide opening in place of the seal to be created for rapid gas flow through the second compartment and into the air bag to rapidly expand the air bag.
