What was the redesign of air bags in 1998?
In 1998-1999, air bags were redesigned by depowering – by removing some of the gas-generating propellant or stored gas from their inflators – and/or by reducing the volume or rearward extent of air bags, positioning them further from occupants, tethering and hybrid inflators.
Why are my air bags not deploying after a crash?
In used vehicles, a possible reason for the air bag not to deploy is that the air bag may not have been replaced after a previous crash. NHTSA recommends that air bags always be replaced after a deployment.
Can a weight sensor prevent an air bag from deploying?
Occupant weight sensors and pattern sensors can be used to prevent an air bag from deploying at all in the presence of children.” For example, NHTSA said the 1999 Hyundai Sonata introduced a weight sensor designed to prevent the passenger air bag from deploying unless a weight of more than 66 pounds is detected on the passenger seat.
When do front airbags deploy for unbelted occupants?
Typically, a front airbag will deploy for unbelted occupants when the crash is the equivalent of an impact into a rigid wall at 10-12 mph. Most airbags will deploy at a higher threshold — about 16 mph — for belted occupants because the belts alone are likely to provide adequate protection up to these moderate speeds.
