Test Procedures

(1) Install the seat and headrest assemblies on the test table and secure all fixtures.

(2) Adjust H-point alignment, height, and lateral spacing according to the standard.

(3) Lock all mechanical adjustments to prevent movement.

(4) Calibrate the load and displacement sensors.

(5) Set test parameters in the PC control software.

(6) Apply static load gradually at the specified loading point.

(7) Record force and displacement data until the target load or failure condition is reached.

(8) Stop the test and save the test data and curves.
