That depends on what you run into :
If you run into a concrete wall that doesn't have any " give " , another vehicle that is
parked , another vehicle that is moving towards you or in the same direction
The force of the collision has to be enough to deploy the airbag(s)
Airbag deployment can happen at any speed. It's not about the speed, but rather the impact that the car feels to deploy the bags.
SRS (Supplimental Restraint System) aka Airbags dont have a set speed that they deploy... They deploy when jolted hard enough or have been strucked in an impact.
Yes, it is possible for an airbag not to deploy when going 35 miles per hour. If the hit was not forceful enough at that speed, it will not deploy because it could do more damage than good.
On sensing a collision an airbag will deploy in an average of just 30 milliseconds.
An airbag depoys when a hard impact its the vehicle and the airbag automatically deploy's before the driver and passengers hit the front of the car/seat.
typically 5 mph +
it will deploy if hit hard enough.
The force of the collision has to great enough
It is suppose to deploy in a frontal crash
Airbag deployment is generally not done on the basis of speed: they deploy mostly when there is a sudden stop in speed which has resulted from an impact.Additional: Most aribag sensors are calibrated to activate when they sense an impact equivelant to striking something at a speed of about 30-35 MPH.
No an airbag will not deploy if the battery is disconnected
The airbag system has a malfunction and will not deploy if needed as long as the airbag symbol stays on.
