Changes to Insurance Institute for Highway Safety (IIHS)

IIHS is considering replacing the SID IIs with a WorldSID 50th percentile male ATD in their Side Impact Crashworthiness crash test protocol to assess the injury risks for the driver occupant. When these tests are executed at Calspan, the ATD is positioned according to the IIHS SICE protocol while following the seat positioning procedure for a WorldSID 50th percentile ATD equipped with a RibEye multi-point deflection measurement system owned by Calspan. The RibEye system reports three-dimensional displacement measurements that are then converted to a resultant deflection for each of the three LED locations on every rib.

In this test, a stationary test vehicle is struck on the driver side by a moving deformable barrier (MDB) fitted with an IIHS deformable barrier element. The 1,500 kg MDB has an impact velocity of 50 km/h (31.1 mi/h) and strikes the vehicle on the driver side at a 90-degree angle.
