Abstract
A passenger protection system comprises an air bag operating circuit having a G sensor and a squib, and a back-up circuit connected in parallel to the operating circuit. A terminal of the parallel circuit including the air bag operating circuit and the back-up circuit is connected to the body earth through a battery mounted in the automobile, and the other terminal thereof is grounded through a diode, thus making it possible to supply power to squib for expansion of the air bag even if the G sensor is short-circuited on the occasion of an automobile collision.
