Abstract
Example air duct assemblies include an air duct including a tubular sidewall that is pliable, the tubular sidewall defining an interior of the air duct, the air duct elongate in a longitudinal direction. Example air duct assemblies include a hoop disposable within the interior of the air duct, the hoop providing the sidewall with support in a radial direction that is substantially perpendicular to the longitudinal direction. Example air duct assemblies include a cable disposable within the interior of the air duct, the cable to extend along a longitudinal length of the air duct, the cable to engage the hoop to help support a weight of the hoop and the tubular sidewall.
