Automotive Seat Seatbelt Anchorage Strength Tester
Automotive Seat Seatbelt Anchorage Strength Test System is designed to evaluate the strength, deformation behavior, and structural integrity of seatbelt anchorage points installed on automotive seats. The system applies controlled static tensile loads to simulate real restraint forces during vehicle operation and crash conditions, helping manufacturers verify seat structures, belt anchorages, and fixing components according to safety regulations. It is widely used for vehicle safety certification, seat development, and quality inspection.
