Igniter for an inflatable occupant restraint

摘要

An igniter for use in a vehicle having gas generating material which upon ignition produces gas for inflating an inflatable occupant restraint. The igniter comprises a pyrotechnic transmission line having one end located adjacent the gas generating material. The pyrotechnic transmission line includes a housing and a plurality of pyrotechnic cords located in the housing and extending for substantially the length of the housing. A pair of electrically conductive members are located at a position spaced from the one end of the pyrotechnic transmission line. Each of the members have a portion disposed within the housing. The members are spaced apart. A spark is generated between the members to heat and thereby ignite the pyrotechnic cords in response to a sensor sensing deceleration of the vehicle at a rate above a predetermined rate of deceleration.
