The sofa headrest lift up hinges manufactured and supplied by BLS Hardware are multi-stage ratchet mechanisms designed for raising and tilting sofa headrests, neck supports, and adjustable backrests. BLS Hardware supplies these functional hinges directly to upholstered furniture manufacturers, sofa factories, hardware distributors, and OEM brands.
Product Overview
These concealed mechanisms allow end-users to manually adjust the inclination of sofa head bolsters to achieve tailored ergonomic seating positions. Engineered with an internal ratchet mechanism, the hinge locks incrementally through multiple upward angles and releases smoothly once pulled to its maximum elevation.
Constructed with dual vertical pivot channels and reinforced base plates, each pair of sofa headrest lift up hinges provides dependable structural stability inside upholstered sofa frames without wobble or mechanical play.
Key Mechanical Features
- Multi-Stage Ratchet Indexing: Internal stepped ratchet track allows precise multi-angle positioning for headrests, armrests, and neck supports.
- Fluid Return Release: Lifting the cushion to its top elevation releases the internal pawl mechanism, allowing smooth return to the horizontal resting position.
- Solid Riveted Pivot Joints: Heavy-gauge steel pivot pins maintain precise alignment across moving links, preventing lateral deflection under head weight.
- Corrosion-Resistant Zinc Plating: Electro-galvanized bright zinc surface finish guards the stamped steel chassis against indoor humidity and atmospheric oxidation.
- Substantial Mechanical Weight: Solid stamped steel components deliver a verified net weight of approximately 2.2 kg per pair for contract durability.
- Multi-Hole Mounting Channels: Symmetrical base bracket flanges feature pre-drilled slotted holes to accommodate diverse screw spacing across timber frames.

Installation Guidelines for Assembly Lines
When installing these sofa headrest lift up hinges on upholstery assembly lines, secure the base channel firmly against the inner timber backrest chassis using appropriate structural wood screws.
Fasten the upper articulating bracket securely to the movable wooden headrest core, ensuring both left and right brackets are parallel and symmetrical.
Always cycle the mechanism manually before applying foam wrapping and fabric upholstery to verify that the ratchet engages crisply and clears internal framing members.
