What speed on impact would the airbags go off on a C220 merc, and where are the sensor points?

Answer 1

Not speed alone there are several things that have to happen to make the air bags deploy. G force angle of the car to the crash and one of those crash sensors getting smashed. If you walked away and the bags did not go off there was a reason next time crash harder. Just kidding! Manufactures do not give out air bag information even to Dealership mechanics. Law suits would follow. Dynamics of car crash vary so greatly. People say I barely hit and the bag went off and other say the bags did not deploy and I was going 45 miles an hour? Trust me AIRBAGS SAVE LIFES

Answer 2

Airbags deploy only when they might be needed to prevent serious injury. Frontal driver and passenger airbags are designed to inflate in moderate to severe frontal crashes equivalent to hitting a solid barrier at 10-12 mph.

Some manufacturers use different inflation thresholds depending on whether people are using their safety belts.

Thresholds of 10-12 mph typically are used for unbelted occupants, but thresholds are higher — about 16 mph — for belted occupants because the belts alone are likely to provide adequate protection up to these moderate speeds.

Answer 3

theres is a whole bunch of math and sensors that are placed around the car for front airbags, side head curtain airbags. They will only go off if the senor believes that it needs to go off.
