Mr Humm presented a summary (PSI-07-06) of MCW 2" rigid abdomen offset sled tests conducted to investigate the influence of pelvis flesh and lower abdominal rib interference on the WorldSID 50th male rib response. The tests were conducted in upright and reclined seating positions using the standard pelvis flesh and a modified (partially cut-away) pelvis flesh. The tests showed that the WorldSID 50th lower abdominal rib responses were not substantially affected by pelvis flesh interference. On the basis of these results, the ISO WorldSID 50th working group had decided not to recommend changing the WorldSID 50th male pelvis flesh geometry.
