Heavy-Duty Black Sofa Headrest & Armrest Ratchet Hinge (BLS-HR260)
A black sofa headrest ratchet hinge is a heavy-duty mechanical dual-pivot friction hardware designed to adjust the elevation, tilt, and forward angle of sofa headrests, lumbar supports, and multi-position armrests. Manufactured by BLS Hardware using high-strength stamped carbon steel and precision internal gear teeth, the BLS-HR260 curved mechanism provides smooth multi-stage ratcheting, high holding torque, and concealed durability for premium functional furniture builders.
Key Features & Engineering Benefits
- Dual-Pivot Articulation: Features independent heavy-duty gear joints at both the base plate and top headrest bracket, enabling complex curved motions and ergonomic multi-angle positioning.
- Multi-Stage Precision Ratcheting: Multiple positive locking gear stops allow users to effortlessly dial in the exact angle for reading, watching TV, or resting, with an automatic reset when pulled past full stroke.
- High-Torque Load Bearing: Heavy-gauge solid steel curved body with reinforced central rivets withstands heavy leaning forces (up to 35–45 kg torque per hinge) without slippage.
- Industrial Matte Black Electrophoresis: Advanced e-coating surface treatment provides complete rust prevention, scratch resistance, and silent, friction-free operation.
- Reinforced Dual Flange Plates: Oval top mounting plate and rectangular bottom chassis flange feature pre-drilled countersunk holes for rigid fastening to wooden or steel internal frames.

Working Principle & Operation Guide
- Forward Ratcheting: Pull the upholstered headrest or armrest forward; the internal spring-loaded steel pawl clicks through each gear step, locking firmly at the chosen angle.
- Full Release & Reset: Pull the headrest all the way forward past the final gear stop; the internal mechanism disengages, allowing the hinge to smoothly return back to its original flat position.
- Concealed Frame Integration: Mounts inside the sofa foam cushion or wooden structural cavity for clean, invisible operation.

Frequently Asked Questions (FAQ)
Q1: Are the left and right hinges identical or handed (pair configuration)?
A: The BLS-HR260 hinges are manufactured as symmetrical left and right matched pairs to ensure balanced lifting torque on both sides of wide headrests.
Q2: Does the black electrophoresis coating chip or peel off during high-friction use?
A: No. Unlike ordinary spray paint, our industrial electro-coating bonds molecularly with the steel substrate, passing 48-hour salt-spray and abrasion tests for extreme durability.
Q3: What is the MOQ and sample lead time for wholesale orders?
A: Our standard MOQ is 500 pairs (1,000 pcs). Quality evaluation samples are available and dispatch within 2-3 business days.
