The electric enabling circuit for manner, and the crew-member conservation system which enable, the ignition possible at least two ignition steps inside the crew-member conservation system separately in ignition possible state

摘要

The invention relates to a passenger protection system which is provided with a safing switch (20). If only one ignition stage (2) of a passenger protection airbag which can be ignited in two stages is ignited by a control device (6), the safing switch being closed and a circuit module (16) output (46) that is parallel to the safing switch is switched to a signal mode corresponding to the closed safing switch. In this way and the second ignition stage (4) can then be ignited by the control device (6) even when the safing switch is no longer closed.
