Abstract
A window shade comprises a head rail, a shading structure, a bottom part, suspension cords connected with cord winding units, and a control module. The control module includes a drive axle assembled with the cord winding units, a sleeve affixed with the drive axle, an arrester assembled around the drive axle, and a release unit. The arrester has a locking state in which the arrester blocks a rotational displacement of the sleeve and the drive axle to keep the bottom part at a desired position, and an unlocking state in which rotation of the sleeve and the drive axle is allowed to lower the bottom part by gravity action. The release unit includes an actuator that is operatively connected with the arrester and has an elongated shape. The actuator can rotate about its lengthwise axis to turn the arrester from the locking to unlocking state.
