Abstract
A stairlift may include a rail, a chair with an armrest, a carrier that has a drive motor and is drivable along the rail, a control unit, and a first input device located at the at least one armrest and configured to provide a signal to the control unit to transport a user in a first driving direction. The control unit may start or stop a movement of the carrier in the first direction based at least on the signal of the first input device. The stairlift may also include a second input device that is separate from the first input device, and configured to provide a signal to the control unit to transport the user in the first driving direction. Further, the control unit may be adapted to start or stop the movement of the carrier based on the signal of the second input device.
