Window blind support assembly

A window blind including a window blind support assembly and a deployable blind assembly including a headrail or a roller tube and a blind substrate;

• wherein the window blind support assembly includes one or more elongate support members;
• a mounting bracket;
• and a locating element;
• wherein one or more of the elongate support members include a pair of spaced apart and opposed side walls, an arm, and a channel floor together defining a longitudinal channel, wherein the arm projects from one of the side walls toward another of the side walls and overlies a part of the channel floor;
• the locating element is slidably coupled to the respective elongate support member within the longitudinal channel;
• the locating element includes a resiliently deformable compression element, and one or more resiliently deformable friction members which engage one or both of the side walls and urge the locating element toward an opposed one of the side walls;
• the mounting bracket defines a retaining portion and a connecting portion;
• and the retaining portion of the mounting bracket is secured to the support member between the channel floor element of the longitudinal channel and the resiliently deformable compression element of the locating element under a spring force applied by the resiliently deformable compression element, whereby the retaining portion of the mounting bracket is secured within the longitudinal channel of the elongate support member at a desired position via the locating element;
• wherein the support assembly further includes a window blind frame member coupled to the elongate support member via the connecting portion of the mounting bracket;
• and wherein the headrail or roller tube of the deployable blind substrate is secured to the window blind frame member.
