Auslösevorrichtung

摘要

The release device (16) has an acceleration sensor (6) coupled to an evaluation stage (5), detecting an impact to provide an impact signal (11), for automatic release of the passenger restraint. The release circuit (15) has a first switch (2) operated by the impact signal connected in series with a second switch (3) operated by an activation signal (12) provided by an activation device (10), evaluating the signal from a piezoelectric sensor (9) for determining the accident risk.
