Head Restrain Test Bench

The static load test bench is a system designed to check the behavior of seats and headrests during rear impact tests in accordance with the ECE R17-R25, FMVSS 202-A, and FMVSS 202 regulations.

The system can apply a constant torsion to a specific point on the seat (the “H point”) by use of elements shaped like human backs and a system of calibrated load actuators. These actuators are applied to one, two, or three seats and accurately measure the maximum deformation angle. Up to three head forms simultaneously apply a constant torsion to the headrests, accurately measuring displacement during the test.

The system tests height retention in accordance with the FMVSS 202A regulation. It is independently or simultaneously conducted without using any additional actuator.
