  1. AMCHP 2005 Conference Injuries During PregnancyTracking & Understandingthe Hidden Epidemic Hank Weiss PhD, Associate Professor Center for Injury Research and Control University of Pittsburgh

  2. Pregnant women NOT wearing seatbelts 3 times more likely to experience fetal death Hyde et al (ObGyn, 2003): Effect of motor vehicle crashes on birth & fetal outcomes in Utah

  3. Why Is This Happening?

  4. Seat Belt Syndrome • Sternum Fracture • Rib Fractures • Clavicle Fracture • Lung Injury • Heart Injury • Thoracic Aorta Injury • Bowel Perforation • Abdominal Aorta Injury • Spinal Injury • Pelvic Injury

  5. Risk of Fetal Death With Lap & Shoulder Belt Research Projections based on Computer Modeling

  6. Normal Pregnancy 38 Weeks Best Possible Case

  7. Normal Pregnancy 38 Weeks Best Possible Case Placenta

  8. Normal Pregnancy 38 Weeks SUBMARINING

  9. L 2 DISC L 1

  10. L 2 DISC L 1 Wedge Shaped Fractures

  11. Risk To Fetus 5X Risk to 0 To 1 Year Old Sibling

  12. Lethal to the FETUS & MOTHER

  13. Required Reaction Force To Stop Submarining

  14. Currently Only 2 Ways To Prevent Submarining Crotch Strap - Pubis Load Knee Impact - Femur Load

  15. Crotch Strap Load To Pubis

  16. Crotch Strap Load

  17. Lethal to the FETUS

  18. Femur Load

  19. Femur Load Works (Knee Impact With Dashboard) Unreliable Too Late FMVSS 208 Sets Femur Load Limits

  20. USPTO Prior Art

  21. High Lap Belt Force Directly Into Abdomen Required Reaction Force

  22. High Lap Belt No Pubis Contact

  23. All Lap Belt Force Directly Into FETUS Lap Belt Force

  24. Crotch Strap Wide Lap Belt (Scoop Injury)

  25. Load Concentration On Neck Load Directly To Fetus

  26. Anything Below The Effective Lap Belt Level That Does Not Contact The Pubis And Stabilize The Pelvis Can And Will Cause SCOOPING INJURY As The Pelvis Submarines

  27. Normal Pregnancy 38 Weeks Best Possible Case Fetus Head

  28. Normal Pregnancy 38 Weeks SUBMARINING

  29. Fetus Head After Submarining Fetus Head At Start

  30. It’s Easy To Get Into Trouble In This Business Unless You Know What You Are Doing

  31. Supplemental Automotive Restraint System For Pregnant Women (SARSPM)

  32. SARSPW
