Aircraft Seat Back Frame & Seat Pan
This series of core load-bearing structures—the back frame and seat pan—is engineered for commercial aircraft economy and business class seating. The back frame utilizes high-strength aviation aluminum alloy profiles via welding/riveting, integrating a mesh tension adjustment system to ensure superior crashworthiness and occupant comfort. The seat pan employs aluminum honeycomb or syntactic foam core with carbon/glass fiber face sheets, thermally bonded to provide rigid support while achieving extreme lightweight performance. Critical joints are reinforced, complying with CCAR 25.853 flammability and CCAR 25.562 16g dynamic impact standards. The modular design facilitates rapid installation and refurbishment, seamlessly integrating with Boeing, Airbus, and COMAC seat systems. It serves as the cornerstone for flight safety and operational cost efficiency.
