A roller blind assembly 10 comprising a web of material 12 mounted to a winding mechanism 14 and extendable between parallel guide tracks 26. A draw bar 20 at the free end of the web has a connection 34 at either end coupled with the guide tracks. Each connection has a first clamp member (42 Fig.2) within an undercut channel (28) in the guide track and a second clamp member (44) engaging a guide track exterior surface. The clamp members are biased by first biasing mechanism (46, 54) to clamp the guide track and hold the draw bar in any extended position. Each connection may have a second biasing arrangement (50,56) which applies an additional biasing force drawing the first and second clamp members towards each other if the draw bar becomes skewed and spacing between the first clamp members increases, acting to maintain the draw bar orthogonal to the guide tracks. The blind assembly may comprise further guide bars (74, Fig.5) disposed rearward of the draw bar to support the web at curved regions of the guide tracks. The assembly may be used as a vehicle panoramic sunroof shade.
