Headed in the right direction

摘要

When a vehicle is impacted at the rear, it is accelerated forward and the seat back transmits a load to the occupant's body, i.e.. whiplash. Enter the head restraint. These components must have specific characteristics to ensure the occupant's safety. To test them, simulating the effects of the body and the head on the seat and the head restraint, the method recommended by UN ECE Transport Division Vehicle Regulations, USA Federal Motor Vehicle Safety Standards (FMVSS), and CE regulations, is the application of quasi-static loads over the seating system.
