摘要 |
A disc inflator having gas cooling and mist removal functions, and reduced in weight and in size in a radial direction. An inflator case (40) has an upper case (36) at an occupant side and a lower case (38) at a side opposite an occupant. A tubular holding member (60) having a separation wall (64) at a base portion thereof is provided in the inflator case. A gas flow path (74) is formed at a periphery of the holding member (60), and communication holes (80) communicating with the gas flow path (74) are formed in the separation wall (64). At a peripheral wall portion (36B) of the upper case (36) is formed a gas ejection hole (76) at a position offset towards an occupant side only by a distance δ from a central position P of a combustion chamber (68). Accordingly, a length (L1) of a flow path from the starting end of the flow path to the gas ejection hole (76) increases, enabling effective heat exchange of a high temperature gas and removal of mist (82). Thereby, a conventionally used filter may be disposed of. |
