Abstract
A lumbar support system for an aircraft seat includes a deformable lumbar support basket having a proximate end and a distal end. The system includes a shape memory alloy tension cable in communication with the proximate end of the deformable lumbar support basket, and the distal end of the deformable lumbar support basket. The shape memory alloy tension cable has a changeable tension length with an electric current through the cable. The system also includes a controller operatively connected with the shape memory alloy tension cable. The controller transmits the electric current through the shape memory alloy tension cable based on the user actuation. The electric current causes the shape memory alloy tension cable to deform the lumbar support basket by tension force applied to the proximate end of the deformable lumbar support basket and the distal end of the deformable lumbar support basket.
