IGNITER AND GAS GENERATOR
Document Type and Number:
WIPO Patent Application WO/2022/186018
Kind Code:
A1
Abstract:
[Problem] To obtain an igniter and a gas generator in which the inhibition of flame transmission to a propellant is suppressed by adjusting the elongation of a cup-shaped member during operation while maintaining the sealing property and the insulating property. [Solution] A disk-type gas generator 100 has a short substantially cylindrical housing in which both ends in the axial direction are closed, and a holding portion 30, an igniter 40 having a squib cover 43, a cup-shaped member 50, a propellant 59, a gas generator 61, a lower support member 70, an upper support member 80, a cushion material 85, a filter 90, etc. are accommodated as internal components in an accommodation space provided inside the housing. The squib cover 43 is formed by molding a thermosetting resin or a thermoplastic resin including an elongation rate adjusting material into a cup shape so that the elongation rate during operation of the igniter 40 is greater than 0% and less than 10%.
