Abstract: A flexible tonneau cover assembly is provided that includes a side rail and a rear rail that is removably securable to the side rail. The rear rail is rotatable between a closed position wherein a flexible cover secured thereto is under tension, and an open position wherein the flexible cover is untensioned. Optionally, the assembly includes a securing member that is securable in a fixed position with respect to the side rail and defines a channel, and the rear rail is rotatable between the open position and the closed position when the rear rail is positioned in the channel of the securing member. Optionally, the flexible cover includes a cable operatively connected to the rear rail, and the side rail receives the cable therein when the rear rail is in the closed position to secure the flexible cover to the side rail.

Abstract: A gap seal for a tonneau cover assembly is provided to seal between a front rail, a sliding element, and a side wall of a vehicle between the front rail and the sliding element. The gap seal includes a base, an extension extending from a first side of the base, the extension being disposed in the front rail, and a series of lips extending from a second side of the base, the lips each having a distal edge making sealing contact with the sliding element and a bottom edge making sealing contact with the side wall. Notches in the bottom of the lips allow the lips to easily move with the sliding element.

Abstract: A flexible tonneau cover assembly includes a pair of side rails positioned on side walls of a cargo box of a motor vehicle, two sliding elements slidably received in the side rails, spring blocks inserted within each side rail, and a spring located between the sliding element and the spring block in each side rail. The flexible tonneau cover assembly also includes a front rail including a first end having an opening for receiving a projection of the first sliding element, and a second end having a latch receivable by the latch receptacle of the second sliding element. A tonneau cover is attached to the front rail and extends to cover the cargo box of the vehicle, which is tensioned by the springs.

Abstract: A flexible tonneau cover assembly includes a pair of side rails positioned on the side wall of a cargo box of a vehicle. A first element is received in the first side rail having a projection extending laterally inward from the first side rail. A second element is received in the second side rail having a laterally inward facing latch receptacle. A front rail includes a first end having an opening for receiving the projection of the first sliding element and a second end having a latch receivable by the latch receptacle of the second sliding element. The tonneau cover is removable by rolling it up, disengaging the latch from the laterally inward facing latch receptacle, lifting the second end of the front rail from the second element, and removing the first end of the front rail from the projection of the first element.
