A window covering slat includes a core material and a covering layer covering thereon. The core material is substantially long, and a surface thereof could be divided into two side surfaces and a continuous surface, wherein one of the side surfaces is on one side of the core material in a longitudinal direction, and the other one of the side surfaces is on the other side of the core material in the longitudinal direction. The continuous surface connects the peripheries of the side surfaces. The continuous surface has a flat segment provided in the longitudinal direction. The covering layer covers the continuous surface, wherein the covering layer has a greater thickness on the flat segment than on any other parts of the continuous surface.

A shutter is provided. First and second side rails have cavities running in a direction from top to bottom, each cavity having an opening along a lateral side. A plurality of pairs of slat supports are present, each pair having a slat support mounted in the cavity of the first rail and mounted in the cavity of the second rail. Each slat support has a first section and a second section. The first section has a shape to slide into one of the cavities, and to stack and nest with an adjacent first section of another slat support in the one of the cavities. The second section protrudes through the opening of the one of the cavities. A plurality of slats are present, each slat being mounted on the second sections of one of the pairs of slat supports.

A shutter assembly including a plurality of shutter panels arranged side-by-side. Each shutter panel has a respective plurality of louvers and a respective operable tilt mechanism configured to adjust the tilt angle of the respective plurality of louvers. A control shaft operates the tilt mechanisms. The control shaft is configured to drive simultaneously the respective tilt mechanisms of all of the plurality of shutter panels.

A control system for a shutter is disclosed. The shutter includes a force-bearing mechanism and a plurality of slats. The control system includes a power source, a driving device connected to the power source to output a first driving force, which drives the force-bearing mechanism to rotate the slats, and a clutch mechanism, which includes an input member and an output member which are drivable to be connected together for synchronous operation, or to be mutually disconnected for independent operation. When the driving device outputs the first driving force, the input member is engaged with the output member, and the first driving force can be transmitted to the force-bearing mechanism through the clutch mechanism to rotate the slats. When the driving device stops, the input member is disengaged from the output member, and the slats and the force-bearing mechanism are rotatable relative to the driving device.

In one aspect, a shutter assembly includes a shutter frame and a plurality of louvers supported by the frame. The shutter assembly also includes a louver drive assembly and a motor positioned within the frame. The motor is configured to rotationally drive a drive shaft extending within the frame. Additionally, the shutter assembly includes a clutch assembly rotationally coupled between the drive shaft and the louver drive assembly. The clutch assembly is configured to disengage or decouple the drive shaft from the louver drive assembly when a torque transmitted through the clutch assembly exceeds a given torque threshold.
