Abstract
A retractable awning adapted to be moved between extended and retracted positions includes a pair of support arms and a pair of rafter arms each of which can be extended or retracted with the awning. A motor rotates a drive shaft and a roll bar to which an awning sheet is connected so that energization of the motor causes the awning to be wrapped around the roll bar when the awning is being retracted or unwrapped from the roll bar when the awning is being extended. A belt system is disposed in each support arm which causes the support arm to extend or retract depending upon the direction of rotation of the motor so that the arms are extended simultaneously with the unwrapping of the awning sheet from the roll bar or retracted simultaneously with wrapping of the awning sheet around the roll bar. A rigid or alternatively resilient brace extends between each support arm and an associated rafter arm for holding the rafter arms in an extended position as the awning reaches a fully extended position. An embodiment of the invention is also disclosed wherein the awning automatically retracts in inclement weather conditions.
