Driver restraints and dummy kinematics

Action shot taken during the frontal offset crash test.

The energy of the crash was absorbed by the front end of the car, preserving the driver's survival space very well.

Smeared greasepaint indicates where the dummy's head contacted the B-pillar, roof rail, grab handle, and head restraint during rebound. Head accelerations from these hits were low.

Forces on the lower right leg were high enough to indicate the possibility of injury.

About the original moderate overlap front test

Side: original test

Rating applies to 2005-08 models

Tested vehicle: 2005 Acura TSX 4-door with standard front and rear head curtain airbags standard and front seat-mounted torso airbags

The Acura TSX was introduced in the 2004 model year. Beginning with 2005 models, changes were made to the side curtain and side torso airbags to improve occupant protection in side impact crashes.

View of the vehicle after the crash with doors removed, showing the side airbags and damage to the occupant compartment.

Action shot taken during the side impact crash test showing the driver dummy's head was protected from being hit by hard structures by the side curtain airbag.

Smeared greasepaint shows where the rear passenger dummy's head was protected by the side airbag.
