Abstract
A lift assist mechanism is provided for assisting lifting of a movable component that can move between lowered and raised positions relative to a fixed structure. The lift assist mechanism includes a lift assist spring connected to a spring shaft, and an elongated track in which an end of the lift assist spring or an end of the spring shaft are movably engaged. A spring lock restrains movement of the spring shaft when a lift assist is not required, and releases the spring shaft when a lift assist is required.
