Most air bags will not deploy at less than 10 miles per hour
the other posibillity is that there was a fault in the air bag system.
The force of the collision , with the front of your vehicle , has to be great enough for the airbags to deploy
Speed up to avoid the collision.
when you get in an accident with another vehicle and you both receive damage to the front of you vehicle.
your car could have been hit by a freight train in the rear and the airbags would not deploy unless, of course, you hit something in the front after the rear end collision had already occurred. the sensors are in the front and are designed to deploy the srs units if the occupants are in danger of going forward not backwards as the case in a rear end collision.
The force of the collision has to great enough
Frontal Airbags will deploy at at least a 55 mph crash or more.
The force that the air bags deploy isn't as great when the collision is less severe
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.
They shouldn't!! the impact sensors are on the front end of the vehicle.
When a vehicle is in a car accident there can be a secondary collision. For example, if car ÒbÓ was rear ended that is the first collision but when that car hit the car in front of them that is the secondary collision.

It doesn't tend to be illegal (of course that varies by state/country) but in the event of a collision, the child would be much safer in the back seat than in the front. Under no circumstances should a child in a rear facing booster seat be placed in the front seat as if the airbags deploy, the child will probably be killed.
