Inflator and occupant head protecting device
First Claim
1. An inflator for ejecting high-pressure gas from inside a container through a gas flow-out opening comprising a gas ejection adjusting mechanism located inside of the container, wherein the gas ejection adjust mechanism is configured to reduce the amount of gas ejected by the inflator at a predetermined time after start of a gas ejection operation.

Abstract
An inflator configured to operate so that during a predetermined time from start of operation thereof, the amount of gas supplied by the inflator is large, and, thereafter, the amount of gas supplied is reduced and wherein the gas is continued to be supplied for a long period of time. The inflator includes first and second gas flow openings and a valve mechanism that operates to selectively open the first gas flow opening. When gas is supplied to the gas flow openings at a pressure equal to or greater than a predetermined value, the valve mechanism opens the first gas flow opening. When the pressure of the gas supplied to the gas flow openings becomes equal to or less than a predetermined value, the valve mechanism closes the first gas flow opening.
