DUPLEX ACTUATION SYSTEM FOR INFLATABLE RESTRAINTS

摘要

A duplex firing initiator for an airbag inflator includes both a primary initiator and a secondary initiator for electrical connection to a Restraint Control Module. In the duplex firing initiator, current is conducted in a forward polarity through the primary initiator to actuate the primary initiator and current is conducted in a reverse polarity through the secondary initiator to actuate at least the secondary initiator.
