Abstract
To achieve an air bag activation device that does not require the use of a mechanical safing sensor, the air bag activation device of the invention comprises: a first sensor for electronically detecting acceleration; second and third sensors, mounted at right and left front ends of a vehicle, for electronically detecting acceleration; a squib driver inserted between a power supply and a squib; a microcomputer for generating from outputs of the first, second, and third sensors a driving signal for driving the squib driver; safing signal generating means for generating a safing signal from the outputs of the second and third sensors; and an AND gate for receiving the driving signal and the safing signal as inputs, and for producing an output which is supplied to the squib driver.
