A damping device of a window covering is provided, including a headrail, a covering material, and a driving device, wherein the driving device is located in the headrail to raise and extend the covering material. The damping device is provided in the headrail, and includes a metal member and a magnetic member, wherein at least a magnetic pole of the magnetic member faces the metal member. The metal member is located within a magnetic field of the magnetic member. Either one or both the metal member and the magnetic member is drivable by the driving device to make the metal member and the magnetic member move relative to each other. Whereby, the damping device is able to provide a desired damping effect at different temperature or after a long period use, such that the rotation of the metal member and the movement of the covering material are slowed down.

Either one or both of the metal member and the magnetic member can be driven by the driving device to cause relative movement therebetween. The damping device is able to provide a desired damping effect regardless of changes in temperature or even after prolonged use. The damping device provides a damping effect which slows down the rotation of the metal member and the movement of the covering material.

The safety device for a chain of a shade. The invention proposes the development of a tamper-proof safety device configured for a chain of a shade, such as the roller type, which, when not being used, is fixed to the body of the chain, and when being used, the chain is free to slide in order to perform the raising and lowering operations of the roller shade.

A locking mechanism is disclosed, which is installed in a movable rail of a window covering, and is passed through by a cord. The locking mechanism includes a locking unit and a pressing member, wherein the locking unit includes a stopping member which is movable between a first position and a second position. The stopping member is normally located at the first position to abut against the cord, which prevents the cord from moving relative to the locking mechanism, whereby to maintain the position of the movable rail. By pressing the pressing member, the stopping member is moved to the second position, where the stopping member no longer abuts against the cord. Therefore, when the movable rail is moved in a direction away from a fixed rail of the window covering, the cord can move relative to the locking mechanism. Whereby, the movable rail can be smoothly moved downward.
