凯发登录Inflators produce a quantity of gas, with a certain composition and temperature, at a controlled rate, which then fills the airbag system to sufficiently cushion an automobile occupant from certain injury scenarios.
Autoliv designs airbag protection throughout a vehicle:
- Stored Gas
A pyrotechnic is a chemical material that burns at a controlled rate to produce gas, heat or particles.
A gas generant is a pyrotechnic whose primary output is gas.
Autoliv’s pyrotechnic inflators contain a core of solid gas generant. During a crash, this generant is ignited and produces a harmless nitrogen-based gas as it burns. This gas is then forced through filters in the inflator which cool the gas and remove particulates. As the gas exits the inflator, it enters the airbag cushion, deploying it in time to provide lifesaving protection for the vehicle’s occupants.
Stored Gas Inflator
Gas is produced by a controlled release of gas that is stored at a high pressure.
凯发登录Unlike our pyrotechnic inflator designs, Autoliv’s stored gas designs rely on compressed gas to deploy the airbag. Our hybrid designs use an internal pyrotechnic heating device to compensate for the cooling effect resulting from the expansion of the compressed gas when the airbag deploys. Other award-winning designs, such as our side impact and head protection inflators, use stored nitrous or helium to inflate our safety restraints. These stored gas technologies offer a cooler gas alternative to solid pyrotechnic inflators.
A hybrid inflator features a combination of stored gas and pyrotechnic technologies.
