The five-point head harness design is widely used in full-face respirators and SCBA facepieces to ensure optimal sealing, stability, and comfort.
1. Improved Face Seal
Five independent pull straps distribute the tension evenly across the head.
This uniform pressure ensures the facepiece maintains a tight seal even during head or body movements, minimizing the risk of air leakage.
2. Enhanced Stability
The harness includes one top strap, two upper side straps, and two lower side straps.
Together, these five anchor points keep the mask firmly in position, preventing shifting or slippage during intense activity such as firefighting or rescue operations.
3. Better Comfort
The five-point configuration spreads the load evenly, reducing pressure points on the scalp and face.
The harness materials—typically elastic rubber or woven fabric mesh—allow flexibility and comfort during long-term wear.
4. Easy Adjustment and Quick Donning
Each strap can be adjusted individually for different head shapes and sizes.
Modern harnesses often feature central-pull tightening, allowing users to quickly secure the mask with one motion.
5. Meets International Standards
The five-point harness design complies with major international standards such as:
- EN 136 (Full Face Mask Standard)
- NFPA 1981 (Firefighter SCBA Standard)
- GB/T 16556 (Positive Pressure SCBA Standard)
