In 1967, a breakthrough occurred in the development of airbag crash sensors when Allen K. Breed invented a mechanically-based ball-in-tube component for crash detection, an electromechanical sensor with a steel ball attached to a tube by a magnet that would inflate an airbag in under 30 milliseconds.early all airbags are designed to automatically deploy in the event of a vehicle fire when temperatures reach 150-200 Â°C (300-400 Â°F). This safety feature, often termed auto-ignition, helps to ensure that such temperatures do not cause an explosion of the entire airbag module.
