Sensor system for releasing passive safety apparatus in car crashes

摘要

A sensor system for the release of passive safety systems such as air cushions, belt tighteners or similar arrangements during car collisions is disclosed. The sensor system is designed to release the passive safety systems only within predetermined limits. The sensor system will prevent release of the safety systems during improper voltage conditions. Asymmetrical limitation of the acceleration-responsive electrical signal is provided. The provision of delay elements and a circuit for avoiding release of the passive systems during ordinary acceleration conditions insure the use of the safety systems only during collision situations.
