Abstract: A passenger protecting apparatus for inflating an air bag or tightening a seat belt is provided that is smaller in size and more reliable than any previously known passenger protecting apparatus. The passenger protecting apparatus has two switches connected in series with a squib. The switches are controlled by a control unit using independent program routines in a redundant manner. The control unit combines front collision and side collision detection in one unit. The control unit controls the switches based on the outputs of several acceleration sensors, by comparing their respective outputs to threshold values.

The damage discrimination circuit produces a second air-bag deploying signal when judging the need of activation of the air-bag. A so-called AND circuit is further employed which actually activates the air-bag when receiving the first and second air-bag deploying signals concurrently.

Abstract: The invention relates to circuits which increase the reliability of a passenger restraint system. In one embodiment, the connection layout with respect to a main power source, such as a vehicle battery, prevents accidental activation in the event certain portions of the wiring become grounded and which enables the activation when required even when some of the wiring is cut. Another embodiment increases the time for a which a diagnostic system can be maintained operative should the connection with the vehicle battery be lost. A third and more complex embodiment features circuits which can estimate the amount of damage which has occurred to the vehicle and predict the displacement of person under the influence of the acceleration (deceleration) caused by a collision.
