Martin-Baker has developed a range of crashworthy seats that meet the specialist safety needs of the helicopter community. Each seat type embodies special features that tailor it to the needs of the occupant and the mission. For example, pilot seats incorporate vertical and fore and aft adjustment while rear cabin crew members have seats that rotate, traverse both fore and aft and sideways and incorporate a special harness that enables the occupant to stand while still secured safely. Pilot seats can also be provided in unarmoured or armoured versions. Features such as these maximize occupant efficiency as well as safety.
