Side curtain airbag
The Audi TT is equipped with side curtain airbags for the
rst time. The limited installation space resulting from the
shape of the bodyshell presented a number of engineering
challenges.
Despite the lack of installation space and the absence of a
B-pillar, the AudiTT meets the 2013 US statutory require-
ments according to
FMVSS 226 – Ejection Mitigation
.
Description of FMVSS 226 – Ejection Mitigation
•
FMVSS
= Federal Motor Vehicle Safety Standards.
•
226 – Ejection Mitigation
= the protection of vehicle
occupants from ejection through the side windows,
particularly in a rollover accident.
Side airbag
The side airbag in the AudiTT is designed as a thorax-pelvis
airbag, and not as a head-thorax airbag. Head airbags and
head-thorax airbags would obstruct each other if installed
together and thus be less eective in protecting the vehicle
occupants.

Side curtain airbag attachment
Due to the requirements of
FMVSS226 – EjectionMitigation
and the absence of a B-pillar, the side curtain in the AudiTT is
attached by self-tapping screws.
