Role of the Seat in Rear Crash Safety
David C. Viano, October 2002, 514 Pages, CASE Binding
$100.00

Role of the Seat in Rear Crash Safety addresses the historic debate over seatback stiffness, energy absorbing yielding, occupant retention and whiplash prevention; and it provides a scientific foundation for the direction GM pursued in the development and validation of future seat designs. It also describes the multi-year research study into the role of the seat in rear crash safety - first by addressing the need for occupant retention in the more severe rear crashes; and then by addressing the needs for an adequately positioned head restraint and changes in the compliance of the seatback to lower the risks of the whiplash in low-speed crashes.

Chapters covered include:

  • Significance of Rear Crash Injuries
  • A New Procedure to Evaluate Occupant Interactions with the Seat in Rear Crashes
  • Role of the Seat in Rear Crash Safety
  • Performance Criteria for Quasistatic Seat Tests (QST) and Head Restraint Placement
  • Ultra-High Retention Seat
  • Human Head, Neck and Torso Responses to Pendulum Impacts on the Back
  • Self-Aligning Head Restraint (SAHR) System for Whiplash Prevention
  • Energy Absorption Properties of Head Restraints Neck Biomechanical Responses with Active Head Restraint Systems: Rear Barrier Test with BioRID and Sled Tests with Hybrid III
  • High Retention Seat Performance in Quasistatic Seat Tests
  • Plus much more!
