First Claim
Patent Images
1. An occupant protection activation device comprising:
- a first and a second in-vehicle acceleration sensors that are disposed within a vehicle interior and electronically detect acceleration;
a third front-end acceleration sensor, disposed at the center of the vehicle'"'"'s front-end, for electronically detecting acceleration;
a collision determining means for making a collision determination by using at least one of the output signals of the first in-vehicle acceleration sensor and the front-end acceleration sensor;
a first safety determining means for making a safety determination by using the output signal of the first in-vehicle acceleration sensor;
a second safety determining means for making a safety determination by using at least one of the output signals of the second in-vehicle acceleration sensor and the front-end acceleration sensor;
a signal processing means including said collision determining means and said second safety determining means; and
an actuating means for actuating the activating means of the occupant protection apparatus by the AND of the output signal of said first safety determining means and the output signal of said signal processing means.

Abstract
A collision determination is made by using at least one of the output signals of a front G sensor disposed on a vehicle'"'"'s fore-end and an analog G sensor disposed within the vehicle interior; a safety determination is made by using at least one of the output signals of the analog G sensor, the front G sensor, and a safing G sensor; and when both of the collision determining signal and the safing signal indicate the significance, an application specific IC and a transistor switch actuate a squib activating an air bag.
