Overview
This lightweight seat meets FAR 29 and the flammability resistance of FAR part 25.853(b). It has been subjected to the environmental requirements of MIL-STD- 810. The adjustable five point restraint system is certified to TSO-C114. It is capable of accommodating 5-95 percentile range of male and female aircrew. The single point harness quick release can be operated with either hand. The S-92 seat is adjustable in the fore and aft directions and has a vertical height adjustment of 5 inches. Adjustable lumbar support provides added comfort.
Optional sheepskin cushion covers are also available for comfort enhancement. Alternatively a lighter seat, qualified to TSOC39b and fitted in to the S-76 helicopter, is also available.

How it works
A relatively high percentage of helicopter crashes are survivable. This is especially true in modern helicopters with robust structures designed to survive the crash. However, the human body cannot tolerate the crash forces and accelerations. The back and neck are particularly vulnerable to major and often fatal injuries. Our patented crashworthy seat technologies offer reliable and proven solutions to this problem by attenuating crash energy so that forces and accelerations imposed on the seat occupant are below injury thresholds. In the process of attenuating energy, the seat strokes (moves downward) in a controlled fashion. The energy is attenuated by the seat structure over a longer time period and keeps it well below injury thresholds. Martin-Baker has developed the technology and design approach that not only attenuates these loads over a broad weight range, but remains lightweight and affordable.
