Abstract
An automotive air conditioning system mode control film belt that uses a single drive shaft to shift the belt back and forth. The belt follows a continuous loop that begins and ends at the single drive shaft, wrapping around idler rollers, where necessary, to maintain defined runs of the belt against one or more vent windows in a housing. Thin, long, and widely spaced pairs of drive bands at either end of the belt wrap around the single shaft in opposite directions, clear of one another, wrapping or unwrapping from the shaft in opposite directions as it turns in either direction. The belt is thus able to shift back and forth to open or close the vent widows, while air is able to flow unobstructed between the widely spaced belt drive bands and out to the vent windows.
