Abstract
A pyrotechnic inflator using a thermoelectric device decreases the temperature and pressure of a gas generated when the explosive of the inflator is detonated to simplify the structure thereof. The inflator includes the thermoelectric device for receiving a power from an electronic control unit to cool an inflator housing in a predetermined temperature, and a linear flow passage therein. A metal is installed to one side of the flow passage for eliminating minute particles included in the gas generated during the detonation of the explosive and lowering the temperature of the gas. Upon the power supply to the inflator, the inflator housing is cooled to reduce the temperature of the gas generated when the explosive of the inflator is detonated and to decrease the peak explosion pressure, thereby simplifying the structure and facilitating the manufacturing of the inflator.
