I looked up the American regs and they say record event if "non-reversible deployable restraint" was deployed ... or if the vehicle accelerated over a delta-V greater than 8km/h in 150ms. The regulatory record from 20 years ago is available at https://www.federalregister.gov/documents/2006/08/28/06-7094/event-data-recorders https://www.federalregister.gov/documents/2006/08/28/06-7094...
