ABSTRACT:
An air outlet louver assembly (10) includes a housing (12), primary vanes (14,36), secondary vanes (48,49), and a damper door (86). A control handle (58) independently controls the primary and secondary vanes (14,36,48,49), and a wheel (100) controls the damper door (86). Ridges (74) on a secondary vane (48) engage a control fork (66) on the control handle (58) to provide ratcheting control of the primary vanes (14,36) by the control handle (58). A nub (82) on a secondary vane (48) contacts depressions (80) in the housing (12) to provide ratcheting control of the secondary vanes (48,49). Frictional contact between a nub (106) on the wheel (100) and depressions (108) in the housing (12) provide ratcheting control of the damper door (86).
