Abstract
An assistance mechanism includes a base, a rotatable link, a lifting unit and a power unit which provides power to the lifting unit so that the lifting unit drives the rotatable link. A seat is connected to the rotatable link so that when the rotatable link is activated, the user sitting on the seat is transformed from a sit status into a stand status. This effectively assists the user who does not have sufficient muscle forces to stand up by the assistance mechanism.
