Automotive Seat Seatbelt Anchorage Strength Test System
The Automotive Seat Seatbelt Anchorage Strength Test System is a dedicated test bench designed to evaluate the structural strength and deformation behavior of seatbelt anchorage points on automotive seats. The system applies controlled static tensile loads to verify whether seat structures, anchorage points, and related fixing components comply with national and international safety regulations. It is an essential testing device for ensuring occupant restraint safety and vehicle compliance certification.
