When Should an Airbag Inflate?Frontal airbags are designed to inflate in moderate tosevere frontal or near-frontal crashes to help reducethe potential for severe injuries mainly to the driver's orright front passenger's head and chest. However, theyare only designed to inflate if the impact exceeds apredetermined deployment threshold. Deploymentthresholds are used to predict how severe a crash islikely to be in time for the airbags to inflate and helprestrain the occupants.Whether the frontal airbags will or should deploy is notbased on how fast your vehicle is traveling. It dependslargely on what you hit, the direction of the impact, andhow quickly your vehicle slows down.Frontal airbags may inflate at different crash speeds.For example:. If the vehicle hits a stationary object, the airbagscould inflate at a different crash speed than if thevehicle hits a moving object.. If the vehicle hits an object that deforms, theairbags could inflate at a different crash speedthan if the vehicle hits an object does not deform.. If the vehicle hits a narrow object (like a pole), theairbags could inflate at a different crash speedthan if the vehicle hits a wide object (like a wall).. If the vehicle goes into an object at an angle, theairbags could inflate at a different crash speedthan if the vehicle goes straight into the object.Thresholds can also vary with specific vehicle design.Frontal airbags are not intended to inflate during vehiclerollovers, rear impacts, or in many side impacts.In addition, the vehicle has dual-stage frontal airbags.Dual-stage airbags adjust the restraint according tocrash severity. The vehicle has electronic frontalsensors, which help the sensing system distinguishbetween a moderate frontal impact and a more severefrontal impact. For moderate frontal impacts, dual-stageairbags inflate at a level less than full deployment. Formore severe frontal impacts, full deployment occurs.The vehicle has a seat position sensor. Vehicles withdual stage airbags also have seat position sensorswhich enable the sensing system to monitor the positionof the driver seat.The seat position sensor provides information that isused to determine if the airbags should deploy at areduced level or at full deployment2-56Ofrecido por www.electromanuales.com
