Side Air Bag: Description and Operation
SIPS
SIPS airbag
The SIPS airbag with electronic ignition is standard on both front seats. Bag volume is approximately 10 liters.
The airbag is inflated by a gas cartridge located inside the bag. The gas consists of a mixture of Argon (95%) and Helium (5%). (Helium is only used to
be able to carry out leak tracing on the airbag during manufacture). The airbag also contains a pyrotechnic powder charge to heat, and thereby expand the
gas mixture.
The SIPS airbag is triggered approximately 3 ms after impact. The bag reaches its operational pressure after 10 ms. Pressure in the bag begins to fall 25
ms after impact.
The SIPS bag volume has been increased in comparison to the previous version. This results in the rib cage being covered further forward and pressure is
maintained for a longer period. This combination provides better protective qualities.
A new type of connector with a spring lock is used to connect the SIPS airbag to the SRS system. The connector is yellow.
The SRS system runs diagnostics on the SIPS bag up to the ignition wire.
