An automatic retractable awning assembly includes a roller, a flexible canopy rollable on the roller and having an inner edge for connection to a wall and an outer edge secured to the roller, a torsion spring operably connected to a first end of the roller to bias the roller to roll the canopy onto the roller, a pair of arm assemblies supporting opposite ends of the roller and operable to move the roller between a retracted position adjacent the wall and an extended position spaced from the wall, and an electric motor operably connected to a second end of the roller with a gear train to selectively rotate the roller in either direction. Each of the arm assemblies include a vertically extending base arm for connection to the wall, a bottom arm having a first end pivotally connected to the base arm, an extended arm having a first end pivotally connected to the bottom arm and a second end connected to and supporting the roller, a top arm having a first end pivotally connected to the base arm above the bottom arm and a second end pivotally connected to the extended arm, and a gas compression spring extending between the base arm and the top arm for outwardly biasing the arm assembly toward the extended position.
