Overall kinematics very similar for WorldSID 50th and ES2-re All responses were below IARVs for all vehicles for both dummies à All HICs were below 300 and were similar for both dummies à All pubic forces were below 60% of IARV, but they were more
often higher in the WorldSID à Rib responses were all below 80% of IARV but were generally higher for the ES2-re (as a percent of IARV) The WS maximum rib response were mostly from the abdomen rib2 and ES2 thorax rib 3 The Hyundai Tucson, Cadillac CTS, Jeep Cherokee had peak deflections with thorax rib 1 for both dummies This is a work of the U.S. Government and is not subject to copyright in the United States; it may be used or reprinted without permission.

Shoulder deflection, lower spine and pelvic accelerations were
not measured with the ES2-re. For the WorldSID: à Shoulder deflections were relatively low (below 30 mm, except CTS) Elevated response in the Cadillac CTS (58 mm) Driver dummy sits down in the vehicle, airbag caught in B-pillar Hyundai Tucson had questionable data during impact Arm may have been caught between the thorax side air bag/curtain and Bpillar à Lower spine and pelvic accelerations were low except for one vehicle 2010 Kia Forte pelvis resultant acceleration was elevated (~84g’s)
WorldSID dummy: very durable à Nothing damaged

WorldSID legs are longer than SID-IIs WorldSID ankles don’t articulate like SID-IIs WorldSID head and ribs are more rearward with respect to
the H-point WorldSID head CG typically was lower and rearward for all occupants WorldSID H-Point: à Driver and right front passenger typically same as SID-IIs in X
direction, but slightly higher in the Z-direction à Rear passenger more forward (X-dir) and slightly higher (Z-dir) than SID-IIs

Summary of 5th Female: MDB Test Results All HICs were below 650 and were generally similar for both dummies à
Somewhat higher for WorldSID in Kia Forte, Hyundai Tucson, and Hyundai Sonata
Maximum Rib deflections were all below 40 mm à
Rib deflections were higher with SID-IIs in every test. Hyundai Sonata and Suzuki SX4 had the largest difference
à à
WS 5th: Maximum rib deflections were mostly from abdomen rib 1 SID-IIs: Maximum rib deflections were mostly thorax rib 1.
Lower spine peak accelerations were similar for both dummies à
2010/11 Kia Forte results were high for both SID-IIs and WS5th
Shoulder deflection, pubic symphysis, and pelvic accelerations were not
measured with the SID-IIs. For the WorldSID: à à à
Shoulder deflections were all below 35 mm Pubic symphysis forces were all below 1400 N Peak pelvic accelerations were above 80 g’s in 4 of 12 vehicles.
