Upgrade your functional seating and ergonomic motion furniture lines with our heavy-duty sofa headrest lift up hinges (Model: BLS-317). Weighing 2.2 kg per pair and engineered from high-tensile Q235 thickened carbon steel, these multi-angle sofa headrest lift up hinges deliver smooth multi-stage ratchet angle adjustment, solid gear locking, and rock-solid structural stability for modern adjustable couches, functional sectionals, home theater seating, and luxury lounge armchairs.
Multi-Stage Ratchet Angle Adjustment & Ergonomic Head Support
Our heavy-duty sofa headrest lift up hinges are precision-engineered for smooth, jam-free ergonomic positioning:
• Multi-Gear Ratchet Locking: Features a high-precision internal ratchet gear track that allows end-users to adjust the headrest or armrest smoothly through multiple elevation angles, providing tailored cervical and neck support.
• Smooth Reset Mechanism: Simply lift the headrest to its maximum top angle to disengage the ratchet pawl, allowing the cushion to return smoothly to the flat horizontal starting position.
• Solid Hydraulic Riveted Joints: Solid steel pivot pins paired with self-lubricating wear-resistant nylon friction washers ensure whisper-quiet articulation, zero lateral play, and eliminate annoying frame squeaks over decades of use.
• Anti-Slipping Gear Teeth: Hardened carbon steel ratchet teeth prevent sudden collapsing or slipping under heavy dynamic head and neck pressure.
Heavy-Duty 2.2kg Solid Q235 Carbon Steel Construction
Unlike lightweight stamped hinges that sag and bend under daily head pressure, our sofa headrest lift up hinges are built for commercial furniture durability:
• Thickened Q235 Steel Plate: Laser-cut and stamped from 2.5mm–3.0mm high-strength carbon steel, delivering a solid net weight of 2.2 kg per pair.
• Corrosion-Resistant Bright Zinc Plating: Multi-layer electro-galvanizing (silver zinc) finish passes standard 48-hour neutral salt-spray testing, protecting against rust, oxidation, and humidity in all global climates.
• Smooth Burr-Free Finish: 100% deburred and polished edges ensure the metal mechanism never wears, cuts, or frays inner sofa foam and upholstery fabrics.
• 30,000+ Cycle Fatigue Tested: Ratchet gears and pivot joints maintain crisp locking and smooth reset action across thousands of open-close cycles.
