Interactive Cushion Systems
Below is our line of interactive lumbar support cushions designed for aircraft crew and passenger seats. The cushion is comprised of a foam filled, airtight bladder with a two way vent valve installed through the airtight membrane. The cushion begins fully inflated with the ability to be individually contoured to the occupants personal comfort level using the "Push to Adjust" button. While supporting the muscular areas of the back, it also relieving the spine from direct pressure. The valve can be accessed directly through the upholstery cover of the seat back or mate with a Semco Cable Control routed to the side panel or armrest of the seat depending on your needs and design.

Cable Control Systems
Semco Aerospace is the worlds supplier of Interactive Lumbar Supports for aircraft crew seats, and passenger seating. This concept provides a fully passenger adjustable, form fitting back support system that provides support to the muscles of the back while relieving the pressures on the spine. This back support system is remotely adjusted with a cable type control with a variety of customer interface inputs. Here is the traditional button type input, but has been designed to require less that 1” clearance from the outer panel surface. The output mates directly with the Semco lumbar cushion valve.
