The Car Seat Center of Gravity Measuring Tester is a precision testing instrument used to determine the center of gravity position of automotive seats and seat assemblies. By accurately measuring mass distribution, the system provides reliable data to support seat structural design, safety evaluation, and vehicle-level balance optimization.The tester is suitable for complete seats, seat frames, and partially assembled seat structures, and is widely applied in R&D verification, quality control, and compliance testing within the automotive seating industry.

Application

(1) Center of gravity measurement of complete automotive seats, including driver seats, front passenger seats, and rear seats.

(2) Testing of manual seats, power-adjustable seats, and seats with memory adjustment systems.

(3) Measurement of seats equipped with integrated functional modules such as airbags, heating systems, ventilation units, and massage components.

(4) Center of gravity determination for seat frames and semi-assembled seat structures during product development and prototype validation.

(5) Comparative analysis of center of gravity distribution for different seat designs, materials, or structural configurations.

(6) Evaluation of center of gravity variation caused by additional trim parts, covers, or accessory modules.

(7) Verification of lightweight seat designs to support vehicle mass reduction and balance optimization.

(8) Quality control inspection of center of gravity consistency during mass production.

(9) Incoming inspection and supplier evaluation of seat assemblies and seat sub-components.

(10) Support testing for vehicle-level mass distribution studies and dynamic performance analysis.

(11) OEM validation testing and third-party laboratory measurement of seat balance characteristics.

Standards

(1) GB/T 15084 – Measurement methods for automotive seat center of gravity (if applicable).

(2) ISO 7250 – Basic human body measurements for technological design (reference for mass distribution analysis).

(3) ISO 5353 – Earth-moving machinery — Seat index point (reference methodology for seat positioning and mass distribution).

(4) OEM internal standards and enterprise technical specifications.

Note: Applicable standards may vary depending on regional regulations and specific OEM requirements.
