Vehicle passenger restraint device for use in automotive vehicle or the like.

摘要

Disclosed are circuits via which increase the reliability of a passenger restraint system. In one embodiment the connection layout with respect 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.
