Anti Pinch Sofa Headrest Hinge for Upholstered Furniture
The Anti Pinch Sofa Headrest Hinge (Model BLS-180) manufactured and supplied by BLS Hardware is an engineered multi-angle joint designed for adjustable sofa headrests, armrests, and functional backrests. Stamped in our Jinli, Guangdong source factory (Zhaoqing Gaoyao Jinli Zhengkai Hardware Factory) from 2.5 mm cold-rolled steel, this safety-shielded hinge eliminates finger trapping hazards, gear slippage, and joint looseness across modern residential and commercial furniture collections.
Within the integrated BLS manufacturing framework, furniture factories integrate this anti pinch sofa headrest hinge alongside high-load metal sofa legs and precision interlocking sofa connector hardware to build modular seating suites. These articulation mechanisms also function synchronously with heavy-duty sofa bed hardware in multi-functional convertible daybeds.
Key Features of the Anti Pinch Sofa Headrest Hinge
- Safety Anti-Pinch Enclosure: Engineered protective shroud covers internal scissor gears, completely eliminating finger trapping risks and preventing upholstery fabric from jamming in the gear teeth.
- Multi-Position Ratchet Gear: Hardened internal steel teeth provide 5 positive locking angles ranging from 90° to 180° with a 35 N·m anti-slip holding torque.
- Heavy-Gauge Q235 Steel: Stamped from 2.5 mm cold-rolled structural steel arms to withstand excessive downward pressure without bending or warping.
- Smooth Reset Spring Action: Built with high-tensile 65Mn spring steel; push past the maximum angle (180°) to release the locking pawl for effortless, quiet return to the initial 90° stance.
- Galvanized Anti-Rust Finish: Electro-zinc plating (white zinc) protects interior moving parts from ambient moisture, friction wear, and oxidation.
