A headrest assembly for a seat, such as an aircraft pilot seat, including a headrest and a headrest tilt mechanism. The tilt mechanism includes a headrest support, a casing fixed to the headrest support defining a rotation limiter feature determining a full aft headrest position and a full forward headrest position, a driven gear rotatably disposed in the casing, a driver gear rotatably disposed through an axial opening formed though the driven gear, an engaging feature for urging against the headrest, and an actuator for rotating the driver gear. The driven gear and the driver gear have a predetermined gear tooth reduction ratio and a predetermined axial shift distance such that the two gears are arranged in a profile shifted configuration.
