摘要： An electric ignition type initiator applies an electrical signal via a pair of electrical signal input portions to a resistance element connected across the electrical signal input portions to heat the resistance element to cause the heat from the resistance element to ignite an explosive charge and thereby operate a vehicle safety apparatus. The resistance element is formed by etching a film of nickel-chrome alloy provided on the top surface of a substrate. The first side of the resistance element extends in a straight line between the electrical signal input portions, and the second side is inclined from each of the electrical signal input portions so that the width between the first side and each incline on the second side decreases as distance from the respective electrical signal input portion increases. The resistance element has its minimum sectional area where the inclines meet.

摘要： An ignition charge for an initiator provided with an igniting mechanism for setting aflame an ignition charge by the heat generated by an exothermic element connected via a pair of current conducting pins in response to an electric signal is a slurry ignition charge which is formed mainly of a mixture consisting of zirconium as a fuel component and potassium perchlorate as an oxidizing agent component. The ignition charge for the initiator contains nitrocellulose as a binder component in an extrapolated compounding ratio of 0.1% by weight or more and 0.5% by weight or less based on the total amount of zirconium and potassium perchlorate and isoamyl acetate as a solvent in an extrapolated compounding ratio of 12.5% by weight or more and 14.0% by weight or less based on the total amount of zirconium and potassium perchlorate. The ignition charge is spread on the exothermic element and dried. The ignition charge is for the initiator of a gas generator, particularly an electric gas generator.
