First Claim
Patent Images
1. A stored-gas inflator comprising:
- a container including a pressure chamber and a gas outlet for ejecting a gas from the pressure chamber;
a burst shim attached to the gas outlet for sealing the same;
a duct disposed inside the pressure chamber and having one end facing the burst shim and a sealing plate formed at the one end for sealing the same, said sealing plate and said burst shim being connected to each other; and
an initiator attached to the duct for generating gas pressure so that when the initiator is actuated, the gas pressure thereof is guided through the duct to the sealing plate and burst shim to break the sealing plate and burst shim.

Abstract
A stored-gas inflator includes a pressure-resistant container having a high-pressure-gas chamber and a gas outlet for ejecting gas from the high-pressure-gas chamber; a burst shim attached to the gas outlet for sealing thereof; a duct disposed inside the high-pressure-gas chamber having an end facing the burst shim; and an initiator attached to the duct for generating gas pressure so that the gas pressure is guided through the duct to push the burst shim. The stored-gas inflator can easily eject gas with significantly lower bursting pressure to burst the burst shim, and a lower-output initiator can be used.
