  • Ignition capsule, which can be inductively activated, for occupant restraint systems, and a test circuit for said ignition capsule
    Patent number: 6722282
    Abstract: The invention relates to a firing capsule for the gas generator of a passenger restraint system in a motor vehicle, especially for the gas generator of an inflatable impact protection cushion (airbag), in which the electrical energy necessary for detonating the igniting agent is inductively coupled into the firing capsule from the outside by means of alternating magnetic fields. The secondary circuit located in the firing capsule is formed by a closed resistance wire which is applied to a carrier plate of insulating or poorly conductive material.
