Aircraft seat with moveable headrest

An aircraft seat comprising a headrest having a headrest surface and a backrest having a backrest surface,

• wherein the headrest is movable relative to the backrest surface between a first position in which the headrest surface is oriented at a first angle to the backrest surface, and a second position in which the headrest surface is oriented at a second angle to the backrest surface,
• wherein the aircraft seat further comprises a variable length gas strut, the gas strut being coupled at a first end to the headrest and coupled at a second end to a structure of the aircraft seat such that the headrest can be moved between the first position and second position by varying the length of the gas strut between extended and retracted configurations of the gas strut,
• wherein the gas strut comprises a locking mechanism having:
• an unlocked configuration in which the length of the gas strut can be adjusted, thereby allowing movement of the headrest to any position between the first position and second position, and
• a locked configuration in which the length of the gas strut is locked so that the headrest can be held at any position between the first position and second position,
• wherein the aircraft seat further comprises a mechanical linkage comprising an actuatable member located on a surface of the aircraft seat and a trigger configured to move the locking mechanism of the gas strut between the locked configuration and the unlocked configuration upon actuation of the actuatable member, and
• wherein the mechanical linkage comprises an elongate tension member coupled at a first end to the actuatable member and coupled at a second end to the trigger such that actuation of the actuatable member exerts a tensile force on the tension member and causes the tension member to pull the trigger into engagement with the gas strut locking mechanism to move the gas strut locking mechanism from the locked configuration to the unlocked configuration.
