Multi-Segment Flexible Sofa Headrest Hinge for Petal & Curved Sofas (BLS-PS180)
A flexible sofa headrest hinge is a multi-joint articulating hardware mechanism featuring a series of interconnected gear ratchets that bend fluidly into curved, semicircular, or custom geometric profiles. Manufactured by BLS Hardware using heavy-duty stamped carbon steel, the BLS-PS180 allows furniture designers and upholstery factories to create flexible petal sofa backrests, adjustable roll armrests, and ergonomic neck supports that hold their shape under pressure.
Key Features & Engineering Advantages
- Fluid Multi-Joint Articulation: Composed of precision-machined interlocking gear links that bend continuously from a flat line (180°) into a tight arc or U-shape without pinching or binding.
- Reliable Multi-Angle Holding Torque: Internal heavy-duty ratchet springs hold designated angles securely, supporting up to 15–20 kg of leaning force per joint.
- High-Tensile Carbon Steel Construction: Stamped from cold-rolled structural steel plates with heavy-duty center rivets to eliminate lateral looseness and prevent gear slippage.
- Electro-Galvanized Anti-Rust Finish: Multi-layer blue-white zinc plating protects the gear mechanisms from oxidation, humidity, and long-term friction wear.
- Versatile Mounting Flanges: Both end brackets feature multi-hole mounting plates for seamless fastening directly to internal wood, foam, or metal structural frames.

Frequently Asked Questions (FAQ)
Q1: How does the flexible sofa headrest hinge reset back to a straight line?
A: Push or bend the joint fully past its maximum inward angle; the internal ratchet spring disengages and allows the mechanism to smoothly return to its 180° straight position.
Q2: Can BLS Hardware customize the mounting hole spacing on the end plates?
A: Yes. We offer bespoke stamping tooling to modify bracket hole diameters, center-to-center distances, and overall plate lengths to match your wood framing.
Q3: What is the MOQ and sample lead time?
A: Our standard MOQ is 500 sets (1,000 pcs). Free evaluation samples are available and dispatch within 2-4 business days.
