Patent abstract
An automatic winding screen device has a coil spring fixed to a bracket at one end of a winding box, the other end of the coil spring being fixed to a winding shaft, and a damper for alleviating impact and collision noise. Between the damper on a shaft fixed to the winding box and the winding shaft, a one-way clutch mechanism is interposed such that, when the winding shaft is rotated in a screen deploying direction, the connection between the damper and the winding shaft is cancelled while when the winding shaft rotates in a screen winding direction the damper is connected to the winding shaft.
