Abstract
A seat assembly for a patient transport device includes a seat casing including a bottom surface, a rear edge including a rear edge outward-facing surface, where the rear edge extends downward from the bottom surface in a vertical direction, and a lighting unit including a controller including a processor and a memory storing a machine readable and executable instruction set, a sensor communicatively coupled to the controller, and a light output communicatively coupled to the controller, where the light output is coupled to at least one of the bottom surface or the rear edge outward-facing surface of the seat casing, where the light output extends across the seat casing in a lateral direction, and where the light output selectively provides light beneath the seat assembly, where the controller commands the lighting unit to change between an ON position and an OFF position based on a signal from the sensor.
