Abstract
A control system for an occupant restraint system including an airbag which is mounted on an automotive vehicle to protect a vehicle occupant from coming into direct contact with a steering wheel and/or a windshield. The control system comprises a control circuit including a microcomputer. The microcomputer is adapted to execute the following control. A decision is made to operate (inflate) the airbag when a vehicle deceleration exceeds a predetermined threshold level. The threshold level is changed at a timing which is set in accordance with a physical amount representative of a deceleration condition of the vehicle, thereby securely operating the airbag merely by making a simple adjustment to the control system.
