Backrest tester for BIFMA III chair - Fr···

Features:

1. Seat back endurance testing machine conforming to GB BIFMA standard;

2. Closed loop control. The output end of the cylinder is equipped with an American fatigue-grade tension pressure sensor, and the cylinder air pressure control adopts the Japanese SMC gas-electric proportional valve control, which forms a closed loop real-time control with PLC;

3. Multifunctional. The output power of the cylinder can be controlled through the touch screen (used for the durability test of the backrest) or output displacement (used for the durability test of the back tilt mechanism of the chair chassis);

4. Use BIFMA-compliant backrest loading pad to load. When unloading, the loading pad is separated from the chair back, and the backrest rebounds to the initial position by its own structure; compared with the rear pull type, the forward push type is closer to the simulated seat use state. Or it is more standard. (Our opinion) Therefore, it is recommended that the laboratory adopt;

5. Simple clamping structure, all operations can be realized by one person without any tool assistance;

6. The cylinder (power component) can be slid left and right to adjust to meet the BIFMA requirements of the backrest side force durability test.
