Housings for Airbag Ignitors and Seatbelt Pretensioners
Airbags and seatbelt pretensioners are the most well-known among safety devices. Both of these types of equipment are based on similar operating principles: In the event of a collision, the crash sensors transmit an electrical signal to the igniter, which then ignites the initiator charge.
In airbags, this initiator charge ensures that the gas generator rapidly delivers large quantities of gas into the airbag; In seatbelt pretensioners, this charge activates the retractor mechanism, which continues tightening the belt until the passenger has settled in a specific seating position and the risk of injury has been minimized.
In both cases, it is extremely important that the initiator charge is protected long-term to ensure that these vital components will continue to be able to function at all times irrespective of the age of the vehicle.
