In the early 1960s, deployment of rocket-powered ejection seats designed for use at supersonic speeds began in such planes as the Convair F-106 Delta Dart. Six pilots have ejected at speeds exceeding 700 knots (1,300 km/h; 810 mph).
If you meant the speed at which the air-bag comes out of the steering wheel in a crash then I can help. I believe the small cars have an activation of some 150mph and that executive vehicles deploy at some 250mph. The passenger air-bags, in a crash, will deploy at twice the steering wheel bag.
