Abstract: A tonneau system comprising: (a) a plurality of tonneau sections; (b) a retraction system including: (i) a drive roller; (ii) a pulley spaced apart from the drive roller; (iii) a track extending from a location proximate to the drive roller to a location proximate to the pulley; and (iv) a line connected to the drive roller and one or more of the plurality of tonneau sections; wherein the line extends between the one or more of the plurality of tonneau sections and the driver roller when the plurality of tonneau sections are in the closed position, and the line extends from the one or more of the plurality of tonneau sections around the pulley and to the drive roller when the plurality of tonneau sections are in the stored position.

Abstract: 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.

Abstract: A tonneau system that includes one or more tonneau sections and a retraction system. The retraction system has an adjuster shaft; a bias member; a drive roller in communication with the adjuster shaft; one or more lines connected to the one or more tonneau sections and/or to the drive roller; and an adjuster to adjust torque provided by the bias member. The bias member is connected to the adjuster shaft, the drive roller, or both.

Abstract: 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.

Abstract: A retraction system for a tonneau cover system, the retraction system includes: an adjuster shaft; a bias member disposed around the adjuster shaft; a drive roller in communication with the bias member; an adjuster configured to permit rotation of the bias member to increase or decrease an amount of force or torque provided by the bias member; a line connected to the drive roller and to one or more tonneau sections of the tonneau cover system, and a clamp that extends around the adjuster.

Abstract: A tonneau system comprising: (a) a plurality of tonneau sections; (b) a retraction system including: (i) a drive roller; (ii) a pulley spaced apart from the drive roller; (iii) a track extending from a location proximate to the drive roller to a location proximate to the pulley; and (iv) a line connected to the drive roller and one or more of the plurality of tonneau sections; wherein the line extends between the one or more of the plurality of tonneau sections and the driver roller when the plurality of tonneau sections are in the closed position, and the line extends from the one or more of the plurality of tonneau sections around the pulley and to the drive roller when the plurality of tonneau sections are in the stored position.
