Heating element and method of making same for use as an igniter for pyrothecnic charges
A heating element for the ignition of a pyrotechnic charge, e.g. for firing an air bag, has increased stability with respect to transient pulses and electrostatic discharge as a result of a selection of this mass, specific resistance and specific heat capacity. In particular the mass is 1.0x10kg to...

| Zusammenfassung: | A heating element for the ignition of a pyrotechnic charge, e.g. for firing an air bag, has increased stability with respect to transient pulses and electrostatic discharge as a result of a selection of this mass, specific resistance and specific heat capacity. In particular the mass is 1.0x10kg to 4.0x10kg, the specific resistance is 1x10Omegam to 2x10Omegam and the specific heat capacity is 100 W/(kg.K) to 400 W/(kg.K). |
