<p>A window dressing control device includes a housing defining a base, an axially extending hollow cylinder, and an axially extending central shaft, the cylinder and shaft each projecting from the base so as to be substantially parallel and coaxial. The device also includes at least one resilient member between the cylinder and the shaft; a rotatable spool coupled to the housing about the cylinder, and a clutch device mounted on the spool. The resilient member engages the spool and the clutch device, providing a friction brake that bears on the inner wall of the cylinder (or a reinforcing insert within the cylinder) to resist rotation of the spool and clutch.</p> |
