Static and dynamic studies were conducted with conventional and belt integrated vehicular seats. Most conventional seat backs failed with a static FMVSS 207 rearward torque of approximately 700 to 800 Newton meters (Nm) while integrated seats sustain a comparably measured torque of up to approximately 3,500 to 4,000 Nm. Correspondingly greater rearward changes in speed can be sustained by integrated seats with less likelihood of injury to front and rear seated occupants. The dynamic tests demonstrate the importance of testing within the full vehicle interior structure to insure that floor strength is compatible with seat strength to attain optimum occupant protection in stronger seat designs and to assess injury risk to occupants in collapsing seat designs.
