Abstract
An overhead-mounted air bag deployment system, having overhead sensors and a microprocessor to measure and analyze passenger motion as well as vehicle deceleration, for consideration by the microprocessor in deciding whether to deploy the air bag, so as to deal with case-to-case variations in passenger motion. The system also has both a warning light and a warning sleeve on the steering wheel, to discourage the driver from remaining in a position involving an increased risk of injury, and has an automatic bag release means to release the air bag and free the passenger when the collision is over.
