Control Cable for Aircraft Seat Back Recliner
This product line serves as the core transmission component of aircraft seat back recliner systems, connecting the armrest controller/button to the backrest lock mechanism (mechanical lock or actuator). The cable’s push-pull motion drives the lock plate/cam to actuate, enabling backrest unlocking, reclining and position locking. It features a galvanized steel wire rope + flame-retardant sheath + precision-machined end fittings structure, offering small bend radius, high flexibility, precise transmission and long service life. The sheath outer layer can be specified with flame-retardant materials per cabin requirements, accommodating complex installation routing. Cable stroke, length and end-fitting type are fully customizable by seat model, with light actuation force and consistent tactile feedback per adjustment. Validated through over 250,000 cycle tests, it is widely used in passenger and crew seat back recliner systems across Boeing, Airbus and COMAC aircraft, serving as a critical guarantee for reliable seat adjustment mechanism performance.
