Abstract

A patient transport apparatus operable by a user for transporting a patient along stairs. A seat section is coupled to a support structure supporting a track assembly having a belt. A motor selectively generates torque to drive the belt. A user interface is arranged for engagement by the user, and has a direction input control for selecting a drive direction of the motor, and an activation input control for operating the motor to drive the belt. A controller in communication with the motor and the user interface is configured to limit operation of the motor in response to user engagement of the activation input control preceding engagement of the direction input control to prevent driving the belt, and to permit operation of the motor in response to user engagement of the activation input control following engagement of the direction input control to drive the belt in a selected drive direction.
