Automotive Seat Three-Station Headrest and Backrest Static Strength Testing Machine，Vehicle seat static load testing rig
The Automotive Seat Three-Station Headrest and Backrest Static Strength Testing Machine is designed to evaluate the static strength of vehicle seat headrests and backrests. You can use this system to perform assessments on new seat designs, process modifications, material changes, supplier validation, and quality control inspections. It allows for precise, repeatable measurement of load and displacement under controlled conditions, ensuring compliance with automotive safety standards.
Application
This testing machine is suitable for a variety of scenarios in automotive seat design and validation:
Headrest Static Strength Testing: Assess headrest durability and safety under static load.
Backrest Static Strength Testing: Evaluate seatback structural integrity under static load.
Design Verification: Validate new seat designs or material modifications.
Supplier Assessment: Perform qualification and batch inspections of seat components.
Quality Control: Monitor production consistency and ensure compliance with automotive standards.
Typical products tested include automotive seats, headrests, and seatbacks from passenger vehicles, commercial vehicles, and railway seats.
Standards
The machine supports compliance with major international and national standards:
GBI 5083-2019 – Automotive seats, seat anchorage, and headrest strength requirements and test methods.
ECE R17 – Automotive seat and headrest strength test methods and safety requirements.

Installation and operation manual.
Test Procedures
Ensure the sample is properly mounted and secured on the test frame.
Configure test parameters, including stroke, load, and displacement limits, using the software.
Start the test and monitor load and displacement curves in real-time on the control interface.
Record the results; curves and data can be exported for analysis.
Repeat for multiple samples if required.
Maintenance Information
Inspect servo cylinders, load sensors, and optical encoders regularly for wear or damage.
Calibrate load cells and displacement sensors periodically.
Keep the control cabinet and electronics free of dust and moisture.
Ensure all moving parts are lubricated according to the maintenance schedule.
Verify safety limit switches and overload protection functionality.
