TMSI’s Seat Test system is designed to comply with the procedure of the Department of Transportation FMVSS 202. Federal Motor Vehicle Safety Standard (FMVSS) 202 specifies requirements for head restraints to reduce the frequency and severity of neck injury in rear-end and other collisions.
The equipment described will perform tests according to the FMVSS 202 specifications.
Test equipment consists of a seat mounting test bed plate, A-frame loading stand with moveable crosshead, three dual electrohydraulic actuator loading frames, and three electro pneumatic actuator loading frames to apply the prescribed loads. Although designed primarily for FMVSS 202 testing, it can also be used for the appropriate sections of European Regulation ECE-R17.
The SeatTEST™ software is the TMSI’s designed data acquisition software to monitor and control the test equipment and to accurately record the test data. During automatic tests each of the actuator's current test conditions are recorded.
