VARIABLE-BIAS SHUTTER

摘要

A variable-bias shutter system for controlling an airstream through an entryway includes a plurality of louvers. Each louver has a pivot axis and a louver face that includes a first portion arranged to one side and a second portion arranged to the other side of the respective pivot axis. The shutter system also includes a mechanism configured to select a position for the shutter system by rotating in tandem each of the plurality of louvers about the respective pivot axis. An area of the first portion that is exposed to the airstream is smaller than an area of the second portion when the shutter system is substantially closed. Additionally, the area of the first portion that is exposed to the airstream is larger than the area of the second portion when the shutter system is not closed. A vehicle employing the variable-bias shutter system is also disclosed.
