The Car Seat Static Strength Tester is a dedicated testing system used to evaluate the static load-bearing strength of automotive seats, seat fixtures, and headrests under controlled force application.
By applying specified static loads and measuring deformation, displacement, and angular variation, the tester verifies whether seat structures comply with regulatory strength and durability requirements.
The system is widely used for type approval testing, OEM validation, quality control, and R&D evaluation in automotive seating applications.
(1) Static strength testing of complete automotive seat assemblies.
(2) Load-bearing performance evaluation of seat backs under forward and backward static forces.
(3) Static load testing of seat cushions and supporting structures.
(4) Strength verification of headrests under prescribed static loading conditions.
(5) Static strength testing of seat fixtures, seat rails, and mounting brackets.
(6) Structural deformation measurement of seat frames under sustained load.
(7) OEM certification and regulatory compliance testing for automotive seating systems.
(8) Quality inspection and consistency verification during seat mass production.
(9) Comparative strength testing of different seat designs or structural materials.
(10) R&D validation for newly developed seat structures and reinforcement solutions.
(1) GB 15083-2006 – Automobile seats, seat fixtures, and headrest strength requirements and test methods.
(2) GB 11550-2009 – Strength requirements and test methods for automotive seat headrests.
(3) FMVSS 207 – Seating systems strength requirements (static load tests).
(4) ECE R17 – Strength and safety requirements for vehicle seats and head restraints.
(5) ISO 6549 – Road vehicles – Procedure for H-point determination (related seat structural evaluation).
(6) EN 71-1 – Mechanical and physical properties (reference for static mechanical safety testing).
(7) OEM internal standards and enterprise technical specifications for seat static strength testing.
(1) Designed for static strength testing of seats, headrests, and seat fixtures.
(2) Wide load measurement range suitable for various seat structures and components.
(3) High load accuracy ensures reliable and repeatable test results.
(4) Long cylinder stroke supports full displacement and deformation measurement.
(5) High-precision displacement and angular measurement for detailed structural analysis.
(6) High sampling frequency captures complete load–displacement behavior.
(7) Professional test software supports manual and automatic control modes.
(8) Advanced data processing functions including curve analysis and slope calculation.
(9) Robust mechanical structure ensures stability during high-load static testing.
(10) Integrated safety protection for secure and controlled operation.
