Abstract
Abstract A retractable awning assembly including an elongated housing mountable on a recreational supporting vehicle and carrying a spring-loaded elongated roller, an awning having an inner edge attached to the roller and an outer edge secured to an elongated lead bar, and means for bracing the awning in an extended position. The bracing structure includes main brace arms pivotally connected to the ends of the lead bar to extend between the lead bar and anchors on the vehicle, and stabilizer arms pivotally attached to the brace arms to extend between the brace arms and anchors on the housing. The brace arms are channels which receive the stabilizer arms for storage, and the lead bar also is a channel which receives the main brace arms for storage, with the stabilizer arms nested in them. In an alternative embodiment, the inner edge of the awning is attached to the receptacle, and the awning is retracted by rolling it upon the lead bar.
