The paper is divided into three sections describing design considerations of the: A) System, B) Electronic Diagnostic Module and C) Crash Sensors. An Abstract from each of these sections follows: System In a vehicle crash event, the inflatable restraint system functions in considerably less than 100 milliseconds. The state and rate of deployment at any given time during the crash event determines the system effectiveness across the range of occupant seating conditions and vehicle crash situations. The inflatable restraint system which includes the inflator and bag assembly, diagnostic module, crash and safing sensors, is designed to perform in concert with other vehicle subsystems, such as the vehicle structure, steering control system, instrument panel, seat belts, and the seats. This paper examines these critical interrelationships that are considered in order to achieve occupant protection in a vehicle equipped with an inflatable restraint system.
