Abstract
An improvement to foldable headrests remote actuators by providing a tube mounted spring compensator to facilitate movement between a stowage position and an operating position. The spring compensator is inserted concentrically within the hollow tubes that support the adjustable headrests to boost or compensate for the lack of force routinely experienced under cold weather use or aging of materials. The spring compensator is positioned inside the headrest support tube to help pull the cable up through the seat when the seat and headrest are returned from a stowage position to a passenger seating position. The spring compensator inside the headrest support tube allows the use of a smaller torsion spring in the headrest and reduces the stress on the components in the mechanism.
