FLEXIBLE LUMBAR SUPPORT OF AIRCRAFT SEAT
DRIVE
November 23, 2016
A flexible lumbar support (10) for an aircraft seat (12) includes a frame (14) and flexible seat pad (24) connected thereto for supporting a seat user. At least first and second rods (36,38) are spaced from each other and the frame (14), extend across and are secured to the seat pad (24), and define respectively at least first and second control lines (50,52) about which the seat pad (24) is rotatable. A third rod (40) is spaced from the seat pad (24), extends across and is secured to the frame (14), and defines a third control line (54). At least a first actuator (46) extends between and is attached to the first and third rods (36,40). A second actuator (48) extends between and is attached to the second and third rods (38,40). The actuators (46,48) are movable along the frame (14) and pivotable about the third control line (54) for allowing a change of respective positions of the control lines (50,52,54) to generate multiple profiles of the flexible lumbar support (10).
