The primary roller 20 of an awning assembly has an internal cavity 21, an opening between the internal cavity 21 and the exterior of the primary roller 20 and a first arresting element 26. A first awning material 30 is adapted to be unwound from the primary roller 20 when the primary roller 20 rotates in a first direction and wound onto the primary roller 20 when the primary roller 20 rotates in a second direction. A secondary roller 40 is mounted for rotation within the internal cavity 21 of the primary roller 20. One end 52 of a second awning material attached to the secondary roller extends through the opening in the primary roller. A second arresting element 55 is attached to the one end 52 of the second awning material and is adapted to engage the first arresting element 26 of the primary roller, whereby rotation of the secondary roller 40 in the second direction causes the primary roller 20 to rotate in the second direction together with the secondary roller 40.
