Office Chair Pull Back and Armrest Strength Test Machine: Ensuring Safety and Durability

This testing system is essential for furniture manufacturers and quality control laboratories aiming to improve product reliability and meet global ergonomic safety standards.

1. What Is an Office Chair Pull Back and Armrest Strength Test Machine?

The Pull Back and Armrest Strength Test Machine applies controlled pulling or pushing forces to an office chair’s backrest and armrests to simulate long-term use conditions. By analyzing deformation, fatigue, and failure points, manufacturers can optimize chair design and ensure user safety during prolonged usage.

Main Functions:

• Simulates pulling and pressure forces on backrest and armrests
• Tests structure strength and durability under cyclic loading
• Evaluates compliance with international safety standards
• Provides adjustable load, speed, and stroke settings

2. Technical Specifications

• Control system: PLC or computer-based intelligent control
• Load application: servo motor or pneumatic actuator
• Force range: customizable 0–2000N
• Displacement range: up to 500mm
• Testing modes: static load, cyclic load, fatigue test
• Test speed: adjustable from 10–300 mm/min
• Safety protection: overload, emergency stop, and automatic shutdown
• Power supply: AC 220V, 50Hz
• Applicable standards: BIFMA X5.1, EN 1335, ISO 21015

The system provides precise control and real-time monitoring, ensuring consistent and traceable results for every test cycle.

3. Testing Principles

The testing machine uses a servo motor or pneumatic cylinder to apply horizontal pulling or downward pressure on the office chair’s backrest and armrests. The machine measures the load response, deformation, and potential breakage under specific forces and durations.

Typical Test Steps:

1. Fix the chair securely on the test platform.
2. Set pulling angle, distance, and load parameters.
3. Apply cyclic or static force as per standard requirements.
4. Record deformation, load curve, and final results.

This process replicates real usage conditions such as leaning back, arm pressure, and repeated motion, helping identify structural weaknesses.

4. Key Features and Benefits

• High precision control: Servo system ensures consistent and accurate load output.
• Multi-standard compatibility: Meets BIFMA, EN, and ISO test criteria.
• Durable structure: Reinforced steel frame ensures long service life and stability.
• Smart software: Real-time data collection, curve display, and report generation.
• Safety mechanisms: Automatic limit stop, overload alarm, and emergency power cut.

These advantages make it ideal for R&D departments, certification agencies, and manufacturing quality assurance.

5. Applications

The Office Chair Pull Back and Armrest Strength Test Machine is widely used for structural strength testing across various seating products.

• Executive office chairs
• Gaming and ergonomic chairs
• Task and conference chairs
• Reclining and mesh office chairs

It ensures that the furniture can withstand long-term use without compromising comfort or safety.
