A general air bag question

Mar 02, 2009 2 Replies

This morning a car pulled out in front of my sister in law and husband. He didn't have time to brake. He believes the two or three year old Avalon is totaled. Everyone is OK, the sister in law was taken to the hospital for chest pains. Probably due to the seat belt. My question is......... Not one air bag inflated. What would be the reason for having no airbags inflate when you hit something hard enough to total a large vehicle other than fraulty bags or sensors?


Sorry for the trauma to the family. I hope everything checks out OK with the SIL.

There are certain criteria that the sensors must see. I don't know a lot about this area, but I do know that the sensor must see a certain G level purely in the fore-aft direction to trigger the bags. Any component of the G level vector from the side doesn't enter into it.

Unless there are side airbags, presumably...

Glad to hear that Peter's family ok; let's hope chest pain is temporary.
