WorldSID seating procedure used for this testing à Use FMVSS 214 seat cushion setup (mid angle / lowest

height) with seat track at midtrack-20mm à Seat the dummy using the FMVSS 214 test protocol Oscar the seat using J826 per current standard H-point tolerance (add 20mm ± 5mm)

à Use tilt sensors to level the head and thorax (±2.5°)

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.


Summary of 50th Male: MDB Test Results

10

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

External Dimensions

16

Initial look à Use the SID-IIs seating procedure protocol in FMVSS

214 and previous experience with the WS 50th Seat cushion setup (mid angle / lowest height) determined in the rear most position Seat full forward or until knees contact dash and seat back adjusted full upward or until head is level Used tilt sensors in the head and thorax to determine final position Monitored the pelvic angle and pelvis sensor



Seating Procedure

17

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



General Results/Observations

18

Rear Seat à Seatbacks had limited adjustability (5 vehs) Head leveling issues à Final head position slightly different à Alignment of ribs with door different in

some vehicles à Limited ankle articulation Feet sometimes cannot get under front seat, which causes knees to be higher

Question: Can WS 5th ribs be directly compared to the SID-IIs ribs? • SID-IIs has linear pots and ribs all move together • WS 5th has IRTRACs and ribs can move individually 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.

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.


Overall kinematics very similar for WorldSID 5th and SID-IIs
