<p>A retractable sunblind comprising a web of flexible material (12, Figure 4 4) is stored on a roller (14, Figure 4) when retracted, and supported when extended by transverse ribs (18, Figure 4). The ends of the ribs are received in guide tracks 22 on either side of the web. Each guide track has a transitional portion 28 at an inlet end near the roller, in which upper and lower guide track surfaces 22A, 22B converge to guide the rib ends into a main portion 26, where the rib ends are a close sliding fit between surfaces 22A, 22B. To reduce rattling between the rib ends and surfaces 22A, 22B when a rib is located in portion 28, at least one of surfaces 22A, 22B has a region 44 in which the surface is recessed 46 to provide a region with a plurality of spaced peaks to reduce the surface area contacting the rib ends. A vehicle having the above system and a method of reducing noise using the above system are also disclosed.</p> |
