Abstract
A device for sealing a gas fill port of an inflator of a vehicle restraint system, for providing pressure release of gases during bonfire of the inflator. During normal functioning of the inflator, the device can be examined to indicate the amount of compressed gas present in the inflator at the time of deployment. In one embodiment, a seal seals the fill port of the inflator. The seal is made of a material which melts at or just below auto-ignition temperature of the inflator during bonfire to allow the gases to vent from the inflator chamber, thereby preventing the inflator from experiencing extremely high internal pressures. Another embodiment of the device seals the fill port of the inflator and also acts as a tell-tale device, whereupon examination of the device after deployment, the amount of gas present in the inflator at the time of functioning can be determined.
