Abstract
The present invention enhances the safety of a stairlift by providing a movement sensor (46) to detect movement of the stairlift chair, such movement being deemed to indicate that a user is attempting to occupy or leave the chair. Upon detection of such movement, the stairlift hand control (38), and remote call controls (22, 24) are rendered inoperative. A chair occupancy sensor (40) may also be provided to restore power to the hand control (38) when the user is safely seated within the chair.
