AIRBAG TRIGGERING SYSTEM

摘要

A plurality of first accelerometers are positioned forward of the passenger compartment and interconnected between vehicular ground and an airbag ignitor. At least one second accelerometer is positioned with the passenger compartment and electrically connected in series between the airbag ignitor and a reserve source of electrical power thereby providing a first firing path. Electronic circuitry positioned within the passenger compartment and connected to the airbag ignitor provides a second firing path through the ignitor to a passenger compartment ground independent of the vehicular ground which the first accelerometers are connected. This second conductive path is provided for a predetermined or dwell time in response to actuation by any of the first accelerometers. The electrical circuitry also includes prefiltering circuitry.
