Pyrotechnic, stored gas and hybrid airbag inflators are used to fill the airbag cushion during a crash. Autoliv’s single-stage and dual-stage airbag inflator technologies are proven to meet the most stringent governmental and customer requirements worldwide.

Nov 15, 2022 · Yasuzaburou Kobori, a Japanese automobile engineer, solved the problem of creating a lot of gas very quickly in 1964. His ingenuous idea was to use a gas-generating chemical explosion to inflate airbags. The first widespread deployment systems used sodium azide to inflate airbags.

This gas-generating device protects the occupant by receiving a signal from a collision to inflate airbags. Daicel Safety Strategic Business Unit(SBU) develops, manufactures and sells various products such as Inflator for automobile Airbag, Gas Generators for Seat Belt Pretensioners(PGG) and Pyro-Fuse(Volt Breaker).

Hybrid generators are used for the front passenger airbag or side airbag. These types of generators also use a second gas source in addition to the burnup gas. A pressure vessel contains a gas mixture of 96% argon and 4% helium at a pressure of approx. 220 bar.

Aug 9, 1999 · When a car is involved in a crash severe enough to activate the sensing unit(s), an electrical charge is routed to the gas generator, which ignites the fuel. The fuel then creates a tremendous amount of inert nitrogen gas filling the airbag.

Feb 12, 2025 · The increasing demand for vehicle safety features has positioned airbag gas generators as a crucial market segment. Several factors contribute to their growing significance: Regulatory Mandates: Stringent safety standards globally, including Euro NCAP, NHTSA, and UNECE regulations, have made airbags mandatory in most vehicles.

Sep 6, 2022 · Dealers will replace the front-passenger air bag module, free of charge. Owner notification letters are expected to be mailed September 23, 2022. Owners may contact Volkswagen’s customer service at 1-800-893-5298.

Modern vehicles may contain up to ten airbag modules in various configurations, including driver, passenger, side-curtain, seat-mounted, door-mounted, B- and C-pillar mounted side-impact, knee bolster, inflatable seat belt, and pedestrian airbag modules. [2]

The Takata gas generator housing could burst when the passenger airbag is deployed. This may cause small metal parts to become detached from the housing, posing a risk of injury to the occupants. The Audi A4 models affected by this recall were equipped with a Takata passenger airbag and manufactured between 12 May 2003 and 29 September 2011.

Joyson Safety Systems develops and manufactures pyrotechnic, stored gas and hybrid inflators to cover all airbag applications. Airbag Systems / Components — Inflators 01. Pyrotechnic inflators generate gas by combustion of a propellant.
