Abstract

A window shade system and housing-guide assembly for shading a window systemically includes a shade assembly, a bracket element and a guide-cover element. The shade element is furlable and unfurlable about an axis for rotation for selectively shading an outfitted window site. The bracket element includes a bracket-to-support interface portion and a guide-cover attachment portion. The guide-cover element includes a bracket-attachment portion, a shade-cover portion, and a shade-guide portion. The guide-cover element is attachable to the bracket element via mated engagement of the guide-cover attachment portion and the bracket-attachment portion. The shade-cover portion is formed so as to subtend an arc length radially anterior relative to the interface portion. The furled shade element is receivable in a space defined by the shade-cover portion and unfurlable via a shade-letting gap defined intermediate the shade-guide portion and the interface portion.
