Abstract: A spring clip has a first and second retention member. The first retention member retains a first part to the spring clip. The second retention member retains the spring clip in a second part. The second retention member provides for retention in a first and second position. In the first position, the first and second parts are in an engagement position and in the second position, the retention member enables servicing of the first part while still connecting the first and second members.

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).
