In 2013, several MV-22s received communications and seating modifications to support the Marine One presidential transport squadron due to the urgent need for CH-53Es in Afghanistan.
Under the driver's seat was a custom modification.
However, it remains unknown whether modification of seat tilt actually alters the posture of the lumbar, thoracic, and cervical spine, and whether it can aid in spinal unloading.
Thus, a wide range of seating adaptation is possible through modification of chair posture, and dynamic seating options may therefore provide a key feature in reducing or even preventing back pain caused by prolonged static sitting.
In striking the licensing deal with AgustaWestland, a unit of Finmeccanica of Italy, Boeing will be starting with a larger helicopter than Sikorsky, and one that was selected in 2005 partly because it could seat more people with fewer modifications.
The findings of this study suggest that a wide range of seating posture adaptation is possible through modification of chair posture.
In this study, we assessed a modification of a standard airline seat (NewSit) designed to decrease the incidence of DVT on long flights.
At approximately one year into the project, a joint BAe/CoA decision was made to progress the project to completion with an 'affordable' set of modifications, providing the basic two seat capability, increased endurance, and approaching the desired performance.
Home hazard modification (including grab rails, raised seats, lighting, trolleys and removal of rugs) was provided by 60% of services.
There was standardization of the removable seat fixing, for quick extraction, and survival cell modifications.
