A drive chain element for operably connecting a slat of a roll top cover to a drive rail enables more efficient roll top cover operation. The drive chain element includes: an elongate body that defines a longitudinal axis and first and second ends, an inner side of the elongate body configured for engaging an end portion of the slat; first and second hinge elements disposed at the respective first and second ends of the body, the first and second hinge elements configured to define a hinge arrangement between adjacent drive chain elements that facilitates relative pivotal movement therebetween; and first and second pins disposed in a spaced arrangement along an outer side of the body and extending outwardly therefrom; wherein the first and second pins are configured for operably contacting a drive system during operation of the roll top cover.

A locking structure of a vehicle cover includes a vehicle cover, at least two mounting rods, a depressor and a torsion spring. The mounting rods are arranged in parallel. The vehicle cover is laid on the mounting rods. The depressor is rotatably mounted on the mounting rods through the torsion spring, and cooperates with the mounting rods to clamp the vehicle cover. The depressor is installed on the mounting rods through the spring, and cover is clamped between the rod and the depressor by the depressor, so that the spring always has a tendency to drive the depressor to clamp the rod, and the cover is pressed against the rods, which means the cover is fixed on the rods, so that a connection between the cover and the rods is more stable and it is not easy for the cover to shake off from the rods.

A transmission stretching truck box covering device with heating control, includes: a clutch-type drive gear box, wherein the drive of the transmission motor drives the electric roller shutter to operate, and the motor is communicatively connected to a roller shutter control board; an electric roller shutter, one end of which is connected to the clutch-type drive gear box, the other end of which is fixed in a driven bearing; a roller shutter cover, which stretches along the extension direction of a side rod; a side rod, which is a support frame in which the roller shutter cover stretches; wherein the inner side of the side rod is a guide rail in which the roller shutter cover stretches, and the outer side is attached to the two sidewalls of the open top cover in the truck box.

An arm assembly for a cover system includes a force mechanism associated within a hollow arm of the assembly that includes a resiliently compressible element, such as a compression spring or gas spring, connected to one end of a cable. The opposite end of the cable is fastened to a non-circular pulley mounted to the container body, so that the cable is wound around the pulley as the arm pivots relative to the container body. As the arm pivots in a stowed direction, energy is stored by the compressible element, and releasing the stored energy causes the arm to pivot toward an extended or deployed position.

A bed cover for a vehicle that may be deployed electromechanically, either on demand or automatically, when a vehicle operator so desires, when predetermined weather conditions are detected, when the vehicle reaches a predetermined speed or experiences predetermined operating conditions, and/or when predetermined aerodynamic drag conditions are detected. The bed cover is deployable from a stowed configuration to one or more use configurations. These use configurations may include a traditional horizontal bed cover and/or an angled “cap-style” bed cover, with the angled bed cover providing enhanced aerodynamic drag reduction characteristics. A vehicle control module and camera, sensor, and/or stop trigger are used to ensure that is safe to deploy and use the bed cover, without negatively impacting an item, animal, or person present in the bed or rear cargo space of the vehicle.

A tonneau system that includes a tonneau cover and a canister. The canister includes one or more tracks for guiding the tonneau cover within the canister during movement of the tonneau cover relative to the canister; and a retraction system including: a drive roller; one or more drive gears; and a bias member that moves the drive roller and the one or more gears to assist in moving the tonneau cover relative to the canister.

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.

A tonneau system that includes tonneau cover and a canister. The canister includes one or more tracks for guiding the tonneau cover within the canister during movement of the tonneau cover into the canister; and a retraction system including: a drive roller; one or more lines connecting the drive roller to the tonneau cover; a bias member that moves the drive roller and the one or more lines to assist in moving the tonneau cover into the canister, and a tensioner.

Disclosed are embodiments of a retractable tonneau cover for a vehicle that has been modified in order to generally minimize the size of a housing of the tonneau cover, providing more vehicle cargo space for a user. The modified retractable tonneau cover can be automatically closed through an electronic system.

A retractable overhead assembly for a vehicle having a retractable cover under tension and an integrated stiffening rod that includes attachment features to selectively connect to a windshield area. The retractable system is self contained within an extrusion keeping the overall package size small and the installation/removal simple. The retractable cover creates a sun shade over the vehicle front cockpit and/or rear passenger area when deployed, and is retractable to a stowed position. The retractable overhead assembly is installable under any hard or soft top assembly configuration, and does not impede use or operation of the hard top or soft top assembly.
