Abstract: An awning control system provides automatic retraction of an extended awning upon detection of awning motion in multiple dimensions caused by windy conditions. The awning control system includes a micro-electro-mechanical system (MEMS)-based accelerometer for motion-based auto-retraction. A single, combined motion sensor/controller module may be located in the motor head and connected to switches and a 12V power source through wires routed along or within the awning framework. The control system operates by gauging the vertical, horizontal (inward/outward), and lateral motion of the leading edge or lead rail of the awning when in a fully or partially extended position. When persistent motion or gust exceeds preset thresholds, the control system will automatically engage the motor to retract the awning. The control system provides full automatic retraction of the awning unless halted or interrupted by additional user input. Manual switching also controls the extension and retraction of the awning.

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.
