Embodiments provide fastening slats for use in a flexible tonneau cover system for covering and sealing a bed of a pickup truck. The fastening slat may include a substantially flat elongated slat having a width and a thickness. The elongated slat may be insertable in a channel of a side rail of the flexible tonneau cover system. The fastening slat may also include a first fastening portion coupled with a substrate that is configured to wrap around at least a portion of the elongated slat such that at least a portion of the substrate contacts a bottom surface of the elongated slat. The first fastening portion may be coupleable to a second fastening portion of a flexible cover of the flexible tonneau cover system that is extendable over a bed of a pickup truck.

A tonneau cover assembly that selectively covers a truck bed of a truck is provided. The tonneau cover assembly includes a cover and a longitudinally extending rail located adjacent a sidewall of the truck bed. The longitudinally extending rail includes an attachment member. The attachment member extends longitudinally along with the rail and at least a portion of the attachment member is located over a portion of the bed. The cover includes a stiffener located adjacent the attachment member of the longitudinally extending rail.

A protective rail for a trailer is formed of an extension or ridge projecting outwardly from a wall of the trailer and extending along at least a part of a length of the wall. The protective rail is provided with tie-down anchors for coupling with tie-downs having couplers such as rings, eyes, or loops. The anchors may tongues formed in the protective rail when the protective rail is cut-out at selected locations along the protective rail. The anchors may be sized and shaped such that the surrounding portion of the protective rail prevents or tends to prevent other trailers or objects contacting the protective rail from damaging or becoming caught on the anchors.

A movable carriage for a movable, tarp enclosure system includes a main body, plural primary support wheels connected to the main body and configured to engage and roll along support rails while supporting the movable carriage, at least one smaller stabilizing wheel connected to the main body and configured to engage the support rails for stabilizing and/or aligning movement of the movable carriage as it moves along the support rail supported by the primary support wheels, and a housing to which the at least one stabilizing wheel is rotatably secured. The housing is provided with one of a guide track and a channel which securely and sliding receives the guide track therein, the main body is provided with the other of the guide track and the channel, and the housing is secured to main body by engaging the guide track within the channel.

A quick release assembly for a side roll tarp is disclosed. The assembly has a roll-tube coupler connected to a roll-tube for rolling and unrolling the side roll tarp. A drive coupler is connected to a shaft of a motor, the drive coupler fitting within an opening in the roll-tube coupler. The drive coupler has a first groove and second groove circumferentially around an exterior of a circular shaft below a head portion of the driver coupler. A quick release pin traverses through a pair of tangential openings in the body of the roll-tube coupler to engage the first or second grooves of the drive coupler, wherein the driver coupler is engaged with the roll-tube coupler when in the first groove allowing the motor to drive the roll-tube and disengaged from the roll-tube coupler when in the second groove allowing the roll-tube to be rotated independently of the motor.

A cover assembly (10) for a vehicle having an integrated fiber windshield rod (14) that is connected to a windshield area and held in place using windshield footman loop portions (22) eliminating the need for a windshield channel or windshield header. The windshield footman loop portions (22) have a plate (24) with a snap stud (26) for attaching a snap eyelet (32) of a web strap (30) to secure the fiber windshield rod (14) in place, which is connected to a fabric cover. The cover assembly (10) has a plurality of straps (16, 20) to secure the sides and rear of the cover assembly to sport bars (18, 21) of the vehicle. The fabric cover assembly (10) creates a sun screen and/or soft top liner effect over at least the vehicle cockpit and is storable in the installed position while the vehicle roof hard top roof assembly or soft top roof assembly is also in installed position on the vehicle.

A vehicle includes a truck bed side panel, a top cover, a clamp, and a plug. The truck bed side panel has a top defining a stake pocket and an overhang extending from the top. The top cover has an upper surface defining an aperture. The clamp is secured to the top cover and engages the overhang to secure the top cover to the top of the side panel. The plug is disposed within the stake pocket and aperture to prevent slippage of the top cover.

A tonneau cover system is provided for a cargo box of a pickup truck. The cargo box including a sidewall having an inboard side, wherein the inboard side extends downward and includes a lower edge. The tonneau cover system comprises a framework assembly positionable over the cargo box of the pickup truck and a bed rail extender having an engagement surface. The bed rail extender is adapted to attach to the inboard side such that the engagement surface is spaced downward from the lower edge of the inboard side. A clamp assembly is operably coupled to the framework system. The clamp assembly has an engaging member selectively positioned between a latched position and an unlatched position. The engaging member is adapted to contact the engagement surface of the bed rail extender in the latched position to retain the framework assembly to the cargo box.

A clamp assembly for use with a tonneau cover assembly is provided. Illustratively, the clamp assembly may include a first clamp member, a second clamp member, a clamp fastener, and at least one shim. The second clamp member is located opposite the first clamp member to form a space located therebetween. The clamp fastener is extended through the space between the first clamp member and the second clamp member. The at least one shim is located in the space between the first clamp member and the second clamp member.
