Heavy-Duty 110 Degree Adjustable Sofa Headrest Hinges (BLS-110 Series)
110 degree adjustable sofa headrest hinges are multi-stage mechanical ratchet joint fittings designed to tilt, elevate, and lock sofa headrests and armrests across progressive ergonomic angles up to 110 degrees. Manufactured by BLS Hardware using high-tensile stamped Q235 carbon steel and precision internal spring pawls, the BLS-110 series provides rigid cervical spine support, quiet ratcheting action, and fail-safe return mechanics for functional furniture factories worldwide.
Key Features & Engineering Benefits
- 0°–110° Multi-Stage Ratcheting: Features internal hardened gear teeth offering 5 to 6 positive locking angle stops, allowing users to dial in optimal head and neck ergonomics.
- Curved Guide Linkage Stability: Integrated with a precision curved steel tracking link that stabilizes the upper angle bracket, preventing side-to-side wobble under heavy leaning pressure.
- Black Anti-Pinch Safety Cam: Fitted with an engineering polymer cap over the gear joint to prevent sofa foam batting and upholstery fabrics from catching in moving teeth.
- Heavy-Gauge Q235 Carbon Steel: Stamped from thickened structural steel plates with heavy solid pivot rivets, resisting bending and tooth deformation over decades of use.
- Multi-Pattern Mounting Flanges: Upper angle bracket and elongated lower mounting blade feature pre-punched multi-hole screw patterns for fast alignment into wood or metal sofa frames.
- Corrosion-Resistant Zinc Coating: Electro-galvanized surface treatment protects internal springs and pivot pins from moisture, oxidation, and friction wear.

How the 110-Degree Ratchet Mechanism Works
- Upward Ratcheting: Lift the sofa headrest forward from 0° flat; the internal pawl clicks into each gear tooth, locking securely at chosen angles up to 110°.
- Full Forward Disengagement: Pull the headrest all the way forward past the 110° maximum stop to release the internal spring pawl.
- Smooth Flat Reset: Fold the headrest back down flat to 0° to restart the ratcheting cycle.
