    Abstract: A covering for an architectural opening may include a brake assembly including a first housing, a clutch on which the first housing may be mounted, a sleeve, a second housing attached to the sleeve, and a spring element attached to the second housing. The brake assembly may permit relatively unrestricted rotation of the first housing in a first direction, and impart rotational resistance to rotation of the first housing in a second direction. A method for assembling a covering for an architectural opening may include coupling a clutch to a first housing, coupling the clutch to a sleeve, coupling a second housing to the sleeve, mounting the second housing over a hub, and positioning a torsion spring between the hub and the second housing. The brake assembly may be used to impart rotational resistance to extension of a shade member, such as to resist unintended extension of the shade member.

    Abstract: A system for incorporation into a retractable covering that includes a flexible lift cord extending from a headrail to a bottom rail. The system includes a flexible protector of a length similar to that of an associated lift cord with the lift cord being operatively connected to the protector. The protector is in turn connected to a fabric extending between the headrail and the bottom rail at predetermined spaced locations so that any loop of protector formable is limited by the spacing between the locations at which the protector is connected to the fabric. The maximum size of a loop so formed in the protector and thus the lift cord associated therewith is insufficient to encapsulate a body part of a child or infant.

    Abstract translation: 一种用于结合到可伸缩覆盖物中的系统,其包括从头轨延伸到底部轨道的柔性起重绳索。 该系统包括具有与相关提升绳的长度相似的长度的柔性保护器,其中提升绳可操作地连接到保护器。 保护器又连接到在预定的间隔位置处在头轨和底轨之间延伸的织物,使得可形成的保护器的任何环都受到保护器连接到织物的位置之间的间隔的限制。 如此形成在保护器中并因此与其相关联的提升绳索的环的最大尺寸不足以包封儿童或婴儿的身体部分。

    Abstract: An architectural-structure covering and corresponding method of manufacturing, assembly, or the like is disclosed. The architectural-structure covering including a covering comprising a front layer, a rear layer, and an intermediate barrier layer, wherein the intermediate barrier layer is coupled to a rear side of the front layer and to a front side of the rear layer so that the intermediate barrier layer is positioned between the front and rear layers. The architectural-structure covering further comprising a plurality of lift elements arranged and configured to move the covering between extended and retracted positions. The lift elements being positioned being the intermediate and rear layers. In this manner, the lift elements may be sandwiched between the intermediate and rear layers thus rending the lift elements inaccessible, or at least greatly limiting accessibility, to an end user.
