ABSTRACT:
Upon a sudden deceleration of a vehicle, if an inertial body moves a predetermined amount against the urging force of a return spring, the trigger means will be released from engagement with the firing pin. Under the urging force of a spring, the firing pin is released from engagement with the trigger means, strikes and ignites a detonator so as to activate the actuator. The trigger means will not move until the inertial body has moved by the predetermined amount. Only after the inertial body has moved the predetermined amount, will the trigger means start to move suddenly and quickly. Therefore, friction at the time the inertial body engages the trigger means is kept constant. The stable operation of the sensor is thereby assured.
