General introduction
Universal Testing Bench for automobile seats, seat anchorage points, and head restraints strength is designed based on mandatory testing requirements of automotive seat safety regulations such as ECE R17 and GB 15083, and is capable of performing strength tests on car seats, seat mounting points, and headrests. The system should be equipped to carry out static strength tests, dynamic impact tests, and fatigue durability tests, covering the full-process inspection and verification of key components including seat assemblies, mounting points, and headrests.
This test bench is applicable to:
Seat assemblies of M1 passenger vehicles and N1 light commercial vehicles.
Front seats, rear seats, and individual headrests.
Key components such as seat frames, adjustment mechanisms, and mounting points.
