Abstract: A powered truck bed tonneau cover includes a handle operating a clutch to engage and disengage an electric motor from the tonneau cover. The handle is operable whenever the tonneau cover is open. A Hall sensor measures the position of the cover and a user may select closed and open positions for powered operation. A drive assembly of the powered truck bed tonneau cover resides just behind the cab and urges the cover into a spiral to avoid binding.

Abstract: A truck bed cover includes rails attached along truck bed side tops, slats residing laterally between the rails, end caps attached to opposite ends of each slat sliding forward and rearward in the rails, and flexible joiner hinges attaching consecutive ones of the slats. A cover holder resided between truck sides against a truck cab. The cover slides into the holder for storage, and rolls into a spiral inside the holder. Each slat includes two end walls and a center wall. The center wall includes a center “C” shaped portion and vertical portions reaching up from the center “C” shaped portion to a slat top surface and down from the center “C” shaped portion to a slat bottom surface. The slat top is cambered to reduce or eliminate water pooling on the cover.
