Abstract
A headrest extension assist system is disclosed. In embodiments, a headrest extension assist system includes a headrest extension assembly movably coupled to a backrest assembly. The headrest extension assist system may further include an extension assist assembly. The extension assist assembly may be coupled to the headrest extension assembly at one end, and a fixed point relative to the headrest extension assembly at another end. The extension assist assembly exerts an extension force on the headrest extension assembly to offset, or partially offset, an extension resistance force. The extension assist assembly exerts the extension force to extend the headrest extension assembly to at least one of a retracted position, an intermediate position, and an extended position.
