Roof and Seat Airbag Inflator Product Description
This product is a dedicated inflator for roof and seat airbags (Airbag Gas Generator), a critical component of the vehicle’s
passive safety system. Its core function is to rapidly release gas
via single explosion technology upon collision, inflating roof and seat airbags within
milliseconds to form a soft, energy-absorbing barrier around
occupants’ heads, torsos, and limbs. This effectively mitigates the
risk of severe injuries from impacts, providing comprehensive
protection for both front and rear passengers.
Designed with space adaptability at its core, the inflator features a compact ∅45*H190mm
cylindrical shape—perfectly fitting into space-constrained
installations such as roof liners and seat structures without
encroaching on valuable interior space. Weighing 1023g, its
lightweight construction minimizes vehicle load, striking a balance
between fuel efficiency and uncompromised safety performance.
Additionally, the inflator is compatible with roof and seat airbag
modules of various vehicle models, offering versatility for
original equipment manufacturers (OEMs) and repair facilities.
Rigorously tested under extreme conditions (including -40℃ to 85℃
temperature ranges and 10-2000Hz vibration), it maintains stable
gas output to ensure reliable protection when it matters most.
