Objective: This study involved a number of different tests addressing theories for recliner and track release of front seats in rear impacts. It addressed the validity of the theories. Method: This study reports on several separate bench and sled tests addressing claims made about recliner and track release of front seats in rear impacts. The following theories were evaluated to see if they were true or a myth: • Recliner teeth slipping with minimal damage to the teeth • Recliner teeth bypass by disengage and re-engage under load without damaging the teeth • Recliner shaft bending and torque releasing the recliners • Track release by heel loading • Track release with occupant load on the seat: • Recliner handle rotation causes recliner release • Double pull body block tests: Results: Many of the theories were found to be myths once actual test data was available to judge the merits of the theory. Data from the tests and images from high-speed movies provide factual information. Conclusion: The data and photos provided demonstrate the robustness of the recliner and track systems in modern seats. Most of the theories are not supported by facts from testing.
