INFLATOR FOR SAFETY AIR BAG IN AN AUTOMOTIVE VEHICLE

摘要

An inflating device for safety air bag or cushion to be installed in an automotive vehicle constructed principally with air bag actuating device, a first sensor provided in the neighborhood of the vehicle cabin and to generate an actuating signal when a change in the running speed of the vehicle within a sampling time exceeds a predetermined value, a second sensor provided in the forward position of the first sensor and to detect the change in the vehicle speed at the initial stage of the collision, a third sensor provided within the vehicle cabin, the sensor having no sampling time relative to a predetermined speed reduction value in the vehicle, and a memory device composed of an electronic circuit or mechano-electric components, in which construction the actuating signal is made to be applied to the air bag actuating device when output signals are generated from the memory device and the first sensor simultaneously.
