RIGID TONNEAU COVER

A retractable cover system includes laterally spaced apart guide rails that define an opening and each provide a track. A drive assembly includes a motor that drives a first gear. The first gear is coupled to a second gear. A cover has multiple slats configured to interlock with one another in a deployed configuration. The slats cooperate with the drive assembly and are slidable in the tracks between first and second positions within the opening in response to actuation of the drive assembly. The slats are stacked onto one another in a stowed configuration. One of the first and second gears is axially movable relative to the other of the first and second gears between coupled and decoupled positions. The motor is coupled to the slats with the first and second gears in the coupled position for automated operation. The motor is disconnected to the slats with the first and second gears in the decoupled position for manual operation.
