Title: Manual disconnect system for powered retractable cover

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority to U.S. Provisional Pat. Application No. 63/271,925, filed on Oct. 26, 2021, all of which is hereby incorporated by reference herein in its entirety for all purposes. 
    
    
     FIELD 
     The present teachings generally relate to a tonneau cover, and more specifically, to a retractable tonneau cover having a manual disconnect system. 
     BACKGROUND 
     Tonneau systems are typically used to cover and protect a cargo bed or unoccupied portion of a vehicle from environmental degradation. Typical tonneau systems include a plurality of structural members that are attached directly to the vehicle to form a frame. A cover is then secured to the frame, preventing moisture, debris, or unwanted objects from entering the cargo bed or unoccupied portion and damaging cargo or the vehicle itself. The tonneau system may include a rigid frame design, such that when fully assembled and attached to the vehicle, the frame creates a unitary structure. The tonneau system may also include one or more rails that movably secure the cover so that the cover may be retracted by rolling or folding the cover onto itself to uncover only a portion of the cargo bed or unoccupied portion. 
     It may often be desirable to easily open and close a cover to access the cargo bed or unoccupied portion of a vehicle. In an effort to aid with opening and closing of the tonneau cover, many tonneau systems include a motor that opens and closes the cover automatically based upon user input (e.g., a button, a fob, etc.). However, while automatic tonneau systems increase ease of opening and closing the tonneau cover, a user may be unable to open and/or close the cover when the motor is not operational. For example, a user may be unable to open a closed cover if the tonneau system is without power to operate the motor, or if the motor has failed or otherwise been rendered defective. Thus, a user may be required to service the vehicle and repair the tonneau system before the tonneau cover may be opened. 
     Examples of tonneau systems may be found in U.S. Pat. Application No. 17/496,290, filed on Oct. 7, 2021, all of which is incorporated herein in their entirety for all purposes. It would be attractive to have a tonneau system with motorized operation that includes manual accessibility. What is needed is a motorized tonneau cover with the ability to manually open and close the cover. It would also be attractive to have a motorized tonneau system with a mechanical release. What is needed is a motorized tonneau system having a mechanical disconnect system in communication with the drive system of the tonneau cover. Additionally, it would be attractive to have the aforementioned disconnect system be easily operated by a user of the tonneau system. Thus, what is needed is a disconnect system positioned near a tail of the vehicle bed for easy access by the user.

     DETAILED DESCRIPTION 
     The explanations and illustrations presented herein are intended to acquaint others skilled in the art with the teachings, its principles, and its practical application. Those skilled in the art may adapt and apply the teachings in its numerous forms, as may be best suited to the requirements of a particular use. Accordingly, the specific embodiments of the present teachings as set forth are not intended as being exhaustive or limiting of the teachings. The scope of the teachings should, therefore, be determined not with reference to the description herein, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of all articles and references, including patent applications and publications, are incorporated by reference in their entirety for all purposes. Other combinations are also possible as will be gleaned from the following claims, which are also hereby incorporated by reference in their entirety into this written description. 
     The teachings herein generally relate to a vehicle and a system for a vehicle. The vehicle may be any type of automobile, such as a car, truck, SUV, commercial vehicle, or a combination thereof. The vehicle may include a system integrating one or more accessories into the vehicle. The accessories may be assembly as part of the vehicle by the Original Equipment Manufacturer (OEM), may be provided as a secondary aftermarket accessory, or a combination thereof. The accessories may include one or more lights, one or more latches, one or more mechanical disconnects, one or more actuators, one or more mirrors, one or more doors, one or more interior accessories, one or more exterior accessories, or a combination thereof. 
     The accessories may be located near or along a cargo box of the vehicle. The cargo box may be defined as a storage portion of the vehicle adjacent to a cabin of the vehicle. The cargo box may be partially enclosed, fully enclosed, or both. The cargo box may include one or more openings, one or more doors, or a combination thereof. The cargo box may be formed from one or more side rails, one or more fenders, one or more panels, or a combination thereof. The side rails may extend parallel to each other and may be further enclosed by the fenders, panels, or both. 
     The cargo box may include a tailgate. The tailgate may function to at least partially enclose the cargo box. The tailgate may function as an access point into the cargo box. The tailgate may be considered an accessory of the cargo box. The tailgate may be moveable between an open position and a closed position. The open position may be when the tailgate is substantially parallel to the ground and provides an open access point into the cargo box. The closed position may be when the tailgate is substantially perpendicular to the ground and substantially encloses at least a portion of the cargo box. The tailgate may also move and/or be secured in one or more positioned between the open position and the closed position. The tailgate may be manually operated by a user or may be actuated by one or more powered actuators. The tailgate may operate with physical user interaction or may be actuated remotely. 
     The tailgate may be used in conjunction with a tonneau cover. The tonneau cover may function to protect against dirt, debris, water, other contaminants, or a combination thereof from entering an inside of a cargo box. The tonneau cover may be a cover that functions to conceal the inside of the cargo box and/or any contents inside the cargo box. The tonneau cover may be placed over the cargo bed of a vehicle, such as a pickup truck. As such, the tonneau cover may also be considered an accessory of the vehicle. 
     The tonneau cover may comprise multiple enclosure panels or a single panel. One or more of the panels may be slats. One or more of the slats may be moved or repositioned relative to one another to move the tonneau cover between an open position and a closed position. One or more of the slats may be substantially rigid. One or more of the slats may be substantially flexible but may be stabilized with a rigid frame. One or more of the slats may be interconnected to form the tonneau cover. Thus, the slats may be moved, pivoted, or both independent or simultaneously. The slats may also extend transverse to a length of the cargo box. As such, a plurality of slats may be interconnected to cover the cargo box. 
     One or more of the slats may include a channel. The channel may function to increase structural integrity of the slats. The channel may function to receive a component of the tonneau cover, such as a disconnect or other type of interlocking component. The channel may include an opening to receive the one or more components or may be substantially enclosed. The channel may form a U-shape, a V-shape, a C-shape, a D-shape, or a combination thereof. The channel may include one or more flanges projecting inwardly toward each other or away from the channel. The flanges may include a lip or may be substantially planar. The flanges along with one or more portions of the channel may guide a component along the channel in a substantially linear direction along a longitudinal axis of the channel. That is, the flanges and the channel may act as a track to guide the one or more components. 
     To further guide one or more components, the channel of the slats may include one or more notches. The notches may function as a stopping point to stop or otherwise secure the one or more components. The notches may receive a portion of the one or more components, such as a disconnect as described herein, to maintain a position of the component. As such, the component may be released from the notches prior to any further movement along the channel. The notches may be a single notch or a plurality of notches. The notches may be formed in pairs, such as along opposing flanges of the channel, opposing faces or sidewalls of the channel, or both. That is the pair of notches may extend transversely to each other relative to the longitudinal axis of the channel. Additionally, it is envisioned that the notches may be any desired size and/or shape to receive a portion of the one or more components located within the channel. 
     Some of the panels may be slats while others may be a panel of a different structure. For example, a plurality of interconnected slats may form a portion of the tonneau cover. Additionally, a front and/or rear panel may be located at opposing ends of the interconnected slats. The front and/or rear panel may be configured for pivoting, rotation about a hinge-point, or both while the interconnected slats may be substantially free of pivoting and/or rotation, and the slats may be configured for guidance along side rails of the cargo box. Similarly, the tonneau cover may include a front panel located proximately to a cab of the vehicle while a tail slat may be positioned proximately to the tailgate of the vehicle. Thus, it may be gleaned from the present teachings that the tonneau cover may provide various functionality within the slats or other panels of the tonneau cover. 
     The open position of the tonneau cover may be when the tonneau cover, or at least one enclosure panel of the tonneau cover, is free from contacting, engaging, or is spaced apart from: the tailgate, a top edge of the tailgate, the walls of the cargo bed, a top edge or top surface of the one or more walls of the cargo bed, or a combination thereof. The closed or retracted position of the tonneau cover may be when the tonneau cover, or at least one enclosure panel of the tonneau cover, is in contact with, engages, or rests on the tailgate, a top edge or top surface of the tailgate, a top edge or top surface of the one or more walls of the cargo box, or a combination thereof, but applies less force or pressure thereon compared to when the tonneau cover is in the closed or lowered position. Therefore, the tonneau cover may also provide one or more positions where the tonneau cover may be partially open or raised partially closed or lowered, or a combination thereof. For example, a partially opened or partially closed position may be defined as one or more enclosure panels spaced apart from the walls or side rails of the cargo bed while a plurality of interconnected slats remains in contact with the side rails to cover a portion of the cargo box. 
     The tonneau cover may be electronically actuated between the open position and the close position, or one or more positions therebetween. Electronic actuation of the tonneau cover may be triggered by one or more interactions from the user. These interactions may include, but are not limited to: one or more commands entered into a wireless application (e.g., an application on a mobile device, tablet, computer, etc.); one or more buttons or commands entered on a wireless fob (e.g., a key fob); a user nearing the vehicle within a proximity range that senses the users presence and sends a signal for electronic actuation of the tonneau cover; one or more sensors or buttons along the vehicle physically touched by the user; one or more voice commands; one or more physical motions of the user recognized by one or more sensors and/or cameras along the vehicle; or a combination thereof. 
     Actuation of the tonneau cover may be completed by one or more motors. The one or more motors may be positioned anywhere along the tonneau cover. The one or more motors may be located within the confines of the cargo box, the vehicle cab, or somewhere therebetween. It is envisioned that the teachings herein may be advantageously integrated into any automated tonneau cover whereby any type of automated drive system is utilized. For example, the drive system may be a drum drive system, a helical cable drive system, or both. The motor may be a brushless motor, an AC or DC motor, a geared and/or stepped motor, or a combination thereof. Examples of drive systems for tonneau covers can be found in U.S. Application Pat. No. 17/496,290, filed on Oct. 7, 2021, all of which is incorporated herein for all purposes. 
     The tonneau cover may be electronically actuated to retract from the closed position (i.e., a position where the tonneau cover is in contact with the cargo box to enclose the cargo box) to the open position (i.e., a position where the tonneau cover is free of enclosing the cargo box). In the open position, all or a portion of the tonneau cover may be contained within a canister. 
     The canister may function to house one or more panels, one or more slats, or both of the tonneau cover. The canister may house the panels and/or slats in a fully open position of the tonneau cover, in a semi-open position of the tonneau cover or both. The fully open position may be considered retraction of the tonneau cover (e.g., slats of the tonneau cover) into the canister. Thus, when in such a retracted or open position, the slats may be contained in the canister and free from view. To house the slats and/or panels of the tonneau cover, the canister may include a canister body. The canister body may be enclosed by one or more side panels. However, it should be noted that while a visible canister may be mounted within the cargo box (e.g., near a front of the cargo box closes to a cab of the vehicle), the tonneau cover may also be housed within a bulkhead or false bulkhead located within the cargo box of the vehicle. As such, the canister or a storage compartment of the tonneau cover may include a front panel to facilitate opening and/or closing of the canister or storage compartment. 
     The front panel may extend across the opposing side walls or side rails of the cargo box. The front panel may be located nearest a cab of the vehicle where the tonneau cover is housed when in an open or retracted position. The front panel may function to pivot between an open position and a closed position. The open position may be defined as a position where the front panel is disconnected from, or space apart from, the side rails, canister opening, bulkhead opening, or a combination thereof. The closed position may be defined as a position where the front panel is in contact with, or engages, the side rails, canister opening, bulkhead opening, or a combination thereof to enclose the canister and/or bulkhead. Thus, it may be gleaned from the present teachings that the front panel may be actuated by one or more actuator assemblies or striker assemblies, such as those found in U.S. Pat. Application No. 16/953,839, filed on Nov. 20, 2020, all of which is incorporated herein in its entirety for all purposes. 
     As discussed above, the tonneau cover may be driven by a drive system having one or more motors. To facilitate movement of the tonneau cover by the one or more motors, one or more cables may be connected to the tonneau cover (e.g., one or more slats) and maintain communication with the one or more motors. The cable may include one or more engaging portions to communicate with the motor. For example, the cable may be a helical cable that facilitates teeth of a motor gear meshing with the cable to advance the cable along the motor gear, thereby moving the tonneau cover. However, it is envisioned that the cable may be any gauge or configuration that may connect to the tonneau cover to move the tonneau cover. For example, the cable may be free of a coil surrounding a core and may instead include one or more divots, channels, barbs, notches, projections, or a combination thereof that engage the teeth of the drive gear and move the tonneau cover. Additionally, the type of cable may also be selected based upon the drive system configuration being utilized (e.g., a gear drive system versus a drum drive system). 
     It is also envisioned that the cable may be at least partial secured within a casing. The casing may function to protect the cable from debris or moisture that may degrade the cable, thereby impacting performance of the drive system. The casing may partially or fully encapsulate an outer circumference of the casing. The casing may extend along an entire length or a portion of the length of the cable. For example, the casing may enclose the cable except for localized, exposed regions of the cable. Such exposed regions may allow for engagement of the cable with the motor (i.e., a drum and/or drive gear of the motor), allow for connection to one or more slats and/or panels of the tonneau cover, facilitate routing through one or more tight packaging constraints (e.g., a hole having a smaller diameter than a diameter of the casing), or a combination thereof. Therefore, it is envisioned that routing of the casing and/or cable may be particular to a desired configuration for a vehicle. Thus, the casing may be selected based upon varying packaging constraints. 
     The drive system may move one or more slats along side rails to open and close the tonneau cover. The side rails may function to guide the tonneau cover between the open position and the closed position. The side rails may abut one or more surfaces of the cargo box so that the tonneau cover may be secured to the cargo box. The side rails may include one or more projections, one or more protrusions, or both that mate to a surface of the cargo box. For example, the side rails may include a mounting portion that is positioned substantially parallel to a vertical sidewall of a cargo box so that, when installed, the side rail abuts the sidewall in a substantially flush manner (i.e., the abutment is substantially free of gaps between the mounting portion and the vertical lip). The side rails may abut the sidewall in a manner other than substantially flush. For example, a gap may exist between the side rail and the sidewall, yet the tonneau cover system may still properly function. The side rail may be a unitary piece or may comprise a plurality of components. For example, the side rail may be a single injection-molded piece having a plurality of integrated projections. Alternatively, the side rail may include a body having one or more projections fastened or adhered to a surface of the body. 
     The side rails may also include an opening. The opening may function to receive an end portion of the slats and/or panels of the tonneau cover. The opening may be formed between an overhang portion of the side rail - that is, a portion of the side rail that overhands an upper surface of the slats and/or panels - and a lower lip. The slats and/or panels may extend into the opening between the lip and the overhand portion to facilitate guidance of the tonneau cover along the side rails. As a result, the overhand portion and/or the lip may extend towards opposing surfaces of the slats and/or panels to prevent moisture and/or debris from entering the opening. As discussed further below, one or more seals along the overhand portion, the lip, or both, may compressibly engage the slats and/or panels to further prevent moisture and/or debris from entering the opening. 
     The opening may include a wear strip. The wear strip may function to contact the slats and/or panels and guide the slats and/or panels along the side rail. The wear strip may prevent degradation of the side rail due to friction between the tonneau cover and the side rails (i.e., dragging the slats along the side rail). The wear strip may be positioned to support the slats and/or panels or a portion thereof. For example, the wear strip may support an end cap of the slats. 
     The slat end cap may be secured to a terminal end of the slat. The end cap may function to engage the wear strip within the opening of the side rail. The end cap may function to at least partially close the channel of the slat, thereby at least partially containing a component within the channel. The end caps may slide along the wear strip to open and close the tonneau cover. The end caps may act as a riser to ensure the slats sit above the lip of the opening, thereby more freely allowing the slats to move along the side rails while still maintaining sufficient moisture and/or debris protection for the opening. The end caps may also include an opening or aperture to facilitate communication of a component within the channel and a portion of the side rails or the drive system, as further discussed below. 
     As discussed above, the drive system of the tonneau cover may utilize one or more cables connected to the tonneau cover (e.g., connected to slats and/or panels of the tonneau cover) to drive the tonneau cover between the open position and the closed position. To further improve packaging constraints of the tonneau cover, the cable may beneficially be routed through the side rails, thereby fully integrating the drive system within the tonneau cover. That is, the cable may be substantially or entirely hidden from the view of a vehicle user. For example, the side rails may be integrated with bed caps of the cargo box and thus the cables and drive system may also look to be visually integrated with the bed caps of the cargo box. As a result, the tonneau cover may visually look to be an OEM product and not an aftermarket component. 
     To create such integration, the side rails may include one or more channels to route the cables, wires, other items, or a combination thereof. The channels may be fully or partially enclosed to secure the cables. The channels may extend along a length of the side rails so that the cables may be routed into or through holes along the side rails to connect the cables between the tonneau cover and the drive systems through the side rails. As such, the cables may advantageously not encroach on an interior of the cargo box, thereby optimizing storage space within the cargo box. 
     To create such integration, the side rails may include one or more channels to route the cables, wires, other items, or a combination thereof. The channels may be fully or partially enclosed to secure the cables. The channels may extend along a length of the side rails so that the cables may be routed into or through holes along the side rails to connect the cables between the tonneau cover and the drive systems through the side rails. As such, the cables may advantageously not encroach on an interior of the cargo box, thereby optimizing storage space within the cargo box. 
     While there may be many benefits to an automated or motorized drive system for the tonneau cover, a user may be required in certain circumstances to manually release or otherwise move the tonneau cover to access and/or enclose the cargo box. For example, during a power outage (e.g., a dead battery within the vehicle) or a faulty motor, a user may be required to manually move the tonneau cover to access their cargo box. In such a case, a disconnect in communication with the drive system may be utilized to manually disconnect the tonneau cover or slats thereof from the drive system. 
     The disconnect may function to connect one or more slats of the tonneau cover with a drive system of the tonneau cover. Similarly, the disconnect may provide a user a mechanical release to disconnect the one or more slats of the tonneau cover from the drive system. The disconnect may be secured to one or more slats of the tonneau cover, such as a tail slat closest to the tailgate. The disconnect may be secured to the slat within the channel of the slat. For example, the disconnect may be at least partially contained within the channel. Advantageously, such packaging may conceal most or all of the disconnect from a line of sight when the tonneau cover is in a closed or partially closed position. However, the disconnect may still be easily accessible by a user if needed. 
     To optimize ease of disconnection, a single disconnect may be integrated into the tonneau cover. As a result, a user may beneficially disconnect a release mechanism to disconnect the slats or panels of the tonneau cover from engagement with the drive system. Thus, a user may then manually move the slats or panels along the side rails to open and/or close the tonneau cover. However, when needed, it should also be noted that a plurality of disconnects may utilized within a single tonneau cover. For example, a pair of disconnects may be located along the same or different slats near opposing side rails. That is a first disconnect may release the slats or panels of the tonneau cover from a first side rail while a second disconnect may release the slats or panels of the tonneau cover from a second side rail. 
     The disconnect may be fixedly secured to the slat. However, it is envisioned that the disconnect may be movable secured to the slat, such as movably guided along the channel of the slat. Such movement may facilitate connection and/or disconnection between the disconnect and the drive system. For example, a block of the disconnect may be guided along the channel or one or more flanges of the channel. 
     The block may function as a movable member of the disconnect. The block may function as a base of the disconnect. The block may function as a connection point to the drive system. The block may be received by the channel so that the block is guided along the channel. The block may be any desired size and/or shape to fit within the channel. However, it is envisioned that the block is an appropriate size to fit withing the channel yet not release from the channel accidentally through an opening therein. 
     The block may include an extension. The extension may function to connect the disconnect - and thus the one or more slats - with the drive system. The extension may project away from the disconnect towards a side rail of the tonneau cover. Similarly, the extension may project towards a drive system located within the side rail. The extension may extend through an opening of an end cap of a slat to be at least partially received within an opening of the side rail or the extension may stay within the confines of the channel to receive a portion of the drive system. While the extension may be any shape, the extension may include a receiving portion that receives a portion of the drive system. That is, the receiving portion may be a female portion while the drive system includes a male portion that may be inserted or otherwise connected to the female portion. The male portion of the drive system may be located along the cable of the drive system. The male portion along the cable may be a cable extension. 
     The cable extension may function to connect the cable - and thus the drive system - to the disconnect or one or more additional parts of one or more slats. The cable extension may extend from the cable to communicate with the disconnect, such as the receiving portion of the extension of the block tab. The cable extension may extend away from the side rail towards a slat or an end cap thereof. As such, the cable extension may be unobstructed by the casing of the cable. For example, the cable extension may be a localized portion of the cable that is free of casing or the cable extension may extend through a cutout along the case to communicate with the disconnect. The cable extension may be secured to the cable or may be integrally formed (i.e., monolithically formed) with the cable. It should also be noted that while the cable extension described below is a male portion being received by the receiving portion of the block extension, the cable may also include a female portion. For example, the extension of the block may extend as a male portion that is received by a female portion of the cable. 
     Communication between the cable extension and the block tab (e.g., an extension thereof) may maintain connection between the slats and the drive system. To facilitate disconnection, the block may be moved along the channel of a slat to release the cable extension from the receiving portion of the block extension. To create such movement, the block may include one or more bulbs. 
     The bulbs may function to contact the channel and guide the block along the channel. The bulbs may be a contour or other projection extending from the block. The bulbs may be positioned near one or more corners of the block to contact the channel. Each bulb may contact one or a plurality of sidewalls of the channel. The bulbs may be any contour, bump-out, undulation, projection, rounded portion, arcuate portion, or a combination thereof. The bulbs may extend along an entire length of the block or only partially along the length. For example, the extension of the block may be free of any bulbs. 
     The block may also include a cavity to house one or more additional components of the disconnect. The cavity to may function to house one or more movable members of the disconnect. The cavity may be any hollowed portion of the block. The cavity may include one or more openings, one or more cutouts, one or more apertures, or a combination thereof. 
     A lever may be at least partially contained within the cavity of the block. The lever may function to release the disconnect from engagement to the slat or a channel thereof. The lever may function release the disconnect from connection to the drive system. The lever may be pivotally or movably engaged to the block of the disconnect. For example, a pin of the disconnect may pivotally or movably connect the lever to the block, such as by one or more barrels of the lever at least partially secured around the pin. As such, it is envisioned that the block or the cavity of the block may include one or more openings or sufficient clearance to receive all or a portion of the lever. 
     During a release operation of the lever, a tab of the lever may be grasped or pushed by a user. The lever may be pushed away from the channel to disconnect the lever from the channel. For example, as further discussed below, the one or more projections of the lever tab may engage notches along the channel. However, the tab may connect or engage the channel in any desired fashion that may facilitate disconnection between the lever and the channel. As such, the lever may be pushed upward into or towards the block of the disconnect. Therefore, the block may include one or more openings to receive at least a portion of the lever tab. Once the lever tab has been released from the channel, the disconnect may be moved to one or more designated locations along the channel (e.g., one or more additional locations along the channel having a notch), or one or more locations therebetween. 
     To move the disconnect along the channel, a user may grasp either the tab of the lever, a tab of the block, or both. While a portion or most of the disconnect may be contained within a channel of the slat, the lever tab and/or the block tab may project outward through an opening of the channel to provide a user a contact point to release the disconnect from the channel and also move the disconnect along the channel. However, the lever tab and/or the block tab may also be contained within the channel to provide flush packaging. 
     The lever tab may include one or more projections. The projections may function to engage the channel of the slat. The projections may be received by notches along the channel to establish a determined stopping and/or locking point for the disconnect. The projections may be located anywhere along the tab that facilitates releasable connection to the channel. However, the tab may also be free of projections in certain applications. 
     To ensure proper connection between the disconnect and the channel, the disconnect may include a biasing member. The biasing member may function the lever away from the block and/or towards the channel. For example, the biasing member may bias the lever towards notches of the channel to ensure automatic engagement of the projections within the notches when in an appropriate location along the channel. The biasing member may contain a helical portion the is positioned around a pin of the disconnect. The biasing member may also include one or more arms or fingers the abut a surface of the block and/or lever to create a biasing force. The biasing member may be a spring, coil, elastic member, or a combination thereof. 
     Turning now to the figures,  FIG.  1    illustrates a cargo box  12  of a vehicle  10 . The cargo box  12  includes a tonneau cover  16  disposed along an upper surface or edge of the cargo box  12 . The tonneau cover  16  may span between opposing bed caps  24  and may be supported by side rails (not shown) connected to, or integrally formed with, the bed caps  24 . As shown, the tonneau cover  16  is in a closed or extended position, whereby the cover  16  includes a plurality of interconnected slats  32  spanning between a tail slat  34  and a front panel  42  to cover an interior of the cargo box  12 . Therefore, the tonneau cover  16  along with a tailgate  14  of the cargo box  12  and outer fenders  22  of the cargo box  12  may at least partially or fully enclose the interior of the cargo box  12 . 
       FIG.  2    illustrates the tonneau cover  16  of the cargo box  12  in  FIG.  1   . As shown, the tonneau cover  16  is in an open or retracted position, whereby all or a portion of the interior of the cargo box  12  is exposed or otherwise accessible. That is, a user may access the interior of the cargo box  12  via the tailgate or along the top edge of the cargo box  12 . The tonneau cover  16  may be guided along the side rails  26  recessed from, flush with, or protruding from an upper surface of the bed caps  24 . It is envisioned that the tonneau cover  16  may be guided along the side rails  26  by one or more motors (not shown) in communication with the slats of the tonneau cover  16 . The one or more motors may drive the tonneau cover  16  in a direction of closing (Dc) to extend the tonneau cover  16  over all or a portion of the cargo box  12 . Similarly, the one or more motors may also drive the tonneau cover  16  in a direction of opening (Do) to retract the tonneau cover  16 , thereby exposing all or a portion of the interior of the cargo box  12 . During retraction, one or more (e.g., two or more, three or more, all, etc.) slats may be retracted into a canister  18  to house the slats when in an open or partially open position. As shown, the canister  18  may beneficially be positioned at least partially beneath the front panel  42  and extend between opposing inside panels  20  of the cargo box  12 . 
       FIG.  3    illustrates a perspective view of a tonneau cover  16 . The vehicle and cargo box as shown in  FIGS.  1  and  2    has been omitted for simplicity and clarity. A plurality of slats  42  extend between opposing side rails  24 . The opposing side rails  24  are adapted to mount to one or more side walls, top edges, panels, fenders, or a combination thereof of the cargo box of the vehicle. Similarly, the opposing side rails  24  may be integrated with, or otherwise connected to, the bed caps  26  of the cargo box. As discussed above, one or more slats  42  of the tonneau cover  16  may be housed within the canister  18  when retracted. The front panel  42  may be positioned adjacent to or above the canister  18  to form an opening with the canister  18  to receive the one or more slats  42  within the canister  18 . It should be noted that only a portion of slats  32  have been shown in  FIG.  3    to further simplify the structure. 
     Additionally, a tail slat  34  may be interconnected with one or more additional slats  32  of the tonneau cover  16 . The tail slat  34  may be positioned rearmost in the cargo box of the vehicle. As a result, the tail slat  34  may be positioned closest to the tailgate when the tailgate is in an upright position. The tail slat  34  may extend and/or retract with the other slats  32  during articulation. However, in some instances, the tail slat  34  may remain stationary during moving of the other slats  32 . 
       FIG.  4    illustrates a bottom view of a partial tonneau cover  16 . As discussed above, a plurality of slats  32 , including a tail slat  34 , may extend between opposing side rails  26  secured to the cargo box of a vehicle. One or more of the slats  32 , such as the tail slat  34 , may include a channel  36  therein configured to receive a disconnect  60  of the tonneau cover  16 . The disconnect  60  may be supported by opposing flanges  38  of the tail slat  34  so that the disconnect  60  is positioned substantially within the channel  36 . While it is envisioned that the tonneau cover  16  may be operated by one or more motors, a user may still need to manually open the tonneau cover  16  due to a lack of power being received by the one or more motors, a defect in the one or more motors causing the tonneau cover  16  not to articulate correctly, or both. Thus, the disconnect  60  may provide the user access to manually disconnect the tonneau cover  16  (e.g., the one or more slats  32 ,  34 ) from the side rails  26  or a drive system disposed therein. 
     The disconnect  50  may include a block  62  positioned with the channel  36  of the tail slat  34 . A lever  86  may be movably connected to the block  62  by a biasing member  80  so that the lever  86  may be moved by a user to release the disconnect  50  from the side rail  26  or drive system therein. 
     The tail slat  34  may include a plurality of notches  40 . In a connected position, the disconnect  60  may be secured within a first pair of notches  40 A so that one or more projections  92  extending from a tab of the lever  86  are positioned within the first pair of notches  40 A. The projections  92  may be secured in the first pair of notches  40 A due to the biasing member  80  biasing the lever  86  towards the flanges  38  of the tail slat  34  and thus towards the first pair of notches  40 A. As discussed in further detail below, the disconnect may include a portion in communication with the drive system of the tonneau cover  16  or the side rail  26 , thereby mechanically interlocking the disconnect - and by extension the slats  32 ,  34  - with the drive system and/or the side rail  26 . 
     To disconnect the slats  32 ,  34  from the drive system and/or the side rail  26 , a user may apply a force on the lever  86  to press the lever  86  towards the block  62 . That is, the lever  86  may be pushed upward into the channel  36  of the slat  34  to disengage the projections  92  of the lever  86  from the first pair of notches  40 A. Once the projections  92  are disengaged from the first pair of notches  40 A, the disconnect  60  (i.e., the block  62 ) may slide in a direction (S) away from the side rail  26 . A user may slide the disconnect  60  using a tab  66  of the block  62 , a tab of the lever  86 , or both. 
     To secure the disconnect  60  in a position no longer in communication with the side rail and/or the drive system therein (i.e., in a release position), the disconnect  60  may be guided within the channel  36  of the slat  34  until the projections  92  of the lever  86  are secured within a second pair of notches  40 B inwardly positioned relative to the first pair of notches  40 A. Similarly, to reengage the slats  32 ,  34  with the side rail  26  and/or a drive system therein, the projections  92  may be released from the second pair of notches  40 B and the disconnect  60  (i.e., the block  62 ) may be moved in an opposing sliding direction (S) until the projections  92  are once again positioned in the first pair of notches  40 A. 
       FIG.  5    illustrates a sectional view of a tonneau cover  16  having a disconnect  50  as described herein. As shown, the disconnect  50  is in a secured positioned, whereby an extension  64  of the disconnect  60  is in communication with an extension  54  of a cable  50  of the tonneau cover  16  drive system. As discussed above, the disconnect  50  may be positioned within a channel of a slat  32 . It should be noted that while the disconnect  50  has been described as being in communication with a tail slat ( FIG.  4   ), the disconnect  50  may be located within any slat  32  of the tonneau cover  16 . Similarly, a plurality of disconnects  50  (e.g., one or more, two or more, three or more, etc.) may be located within one or more slats  32  of the tonneau cover  16 . 
     When in the secured positioned, the extension  64  of the disconnect  60  may extend through an end cap  44  of the slat  32  to communicate (e.g., connect) to the extension  54  of the cable  50 . As shown, the cable  50  may be at least partially housed within a casing  52  and secured within a cable channel  56  positioned in an opening  28  of a side rail  48 . It is envisioned that the cable  50  may be in communication with one or more motors to drive the tonneau cover  16  between an open position and a closed position, or one or more positioned therebetween. Thus, by engaging the extension  54  of the cable  50  with the extension  64  of the disconnect  60 , the slats  32  of the tonneau cover  16  may remain engaged with the drive system. In the engaged position, the slats  32  or end caps  44  connected to the slats  32  may be guided along a wear strip  46  secured in a slot  48  of the side rail  28  to move between an open and a closed position. 
     Beneficially, a tab  88  of the lever of the disconnect  60 , a block tab  66  of the disconnect  60 , or both, may protrude from the channel of the slot  32 . As a result, a user may easily access the tab  88  of the lever, the block tab  66 , or both to release the disconnect (see  FIG.  6   ). 
       FIGS.  6  and  7    illustrate a close-up view of the disconnect shown in  FIG.  5   .  FIG.  6    illustrates the disconnect in a secured position while  FIG.  7    illustrates the disconnect in a released position. As discussed above and shown in  FIG.  6   , the disconnect may be positioned within a channel of a slat  32  such that an extension  64  of the disconnect extends through an end cap  44  secure to the slat  32 . The extension  64  may extend inwardly into the opening of the side rail  48  so that an extension  54  of the cable  50  extends into a receiving portion of the extension  64  of the disconnect (see  FIG.  8   ). As a result, when the extension  64  of the disconnect and the extension  54  of the cable are in communication, movement of the cable  50  along the cable channel  56  of the side rail  26  results in movement of the slats  32  of the tonneau cover  16 . During such movement, a drive system (e.g., a motor) may move the cable  50 , and thus move the slats  32  along a wear strip  46  positioned beneath a bottom surface of the end caps  44  and secured within a slot  48  of the side rail  26 . 
     As detailed herein, the disconnect may be released to disengage the extension  64  of the disconnect from the extension  54  of the cable  50 . To do so, the disconnect may be released from the channel of the slat  32  and moved in a disconnection direction (D D ). As shown in  FIG.  7   , once the disconnect has been moved in the disconnection direction (D D ), the extension  54  of the cable  50  is free of contact with the disconnect, thereby releasing the slat  32  and end cap  44  from communication with the cable  50 . As a result, a user may advantageously manually operate the tonneau cover  16  to move the one or more slats  32  free from the drive system and cable  50  thereof. 
     Additionally, it can be seen from  FIG.  7    that the extension  54  of the cable  50  may extend through an opening of the cable channel  56 , an opening or cutout along a casing  52  of the cable  50 , or both. As a result, the extension  54  of the cable  50  may extend inwardly toward the end cap  44 , thereby contacting or otherwise being in communication with the extension  64  of the disconnect. 
       FIG.  8    illustrates a perspective view of a disconnect  60  in accordance with the present teachings. The disconnect  60  includes a block  62  forming a body of the disconnect. The block  62  may be configured to be positioned within a channel of a slat of the tonneau cover (see  FIG.  4   ). Once positioned within the channel of the slat, a plurality of bulbs  78  may be positioned to extend along a surface of one or more flanges of the channel, one or more inner surfaces of the channel, or both. As a result, the bulbs  78  may help guide the disconnect  60  along the channel during operation of the disconnect. 
     The block  62  may further include an extension  64  adapted to extend towards an opening within a side rail of the tonneau cover. The extension  64  may include a receiving portion  76  that receives a portion (e.g., an extension) of a cable located within the opening of the side rail, thereby engaging the disconnect  60  to the cable. As a result, the slats of the tonneau cover may be in communication with the cable to be driven by a drive system of the tonneau cover. 
     In certain instances, a user may be required to manually move the slats of the tonneau cover to open the tonneau cover, close the tonneau cover, or both. For example, if a vehicle battery powering the motor of the tonneau cover drive system is drained, a user may be required to manually operate the tonneau cover to access the cargo box. In such circumstances, the disconnect  60  must be released from the cable to manually move the slats of the tonneau cover. 
     To release the disconnect  60 , a lever  86  positioned within a cavity of the block  62 , as seen through the cutout  70  of the block  62 , may be articulated upward until projections  92  along a tab  88  of the lever  86  are received into openings  68  of the block  62 . As a result, the projections  92  and thus the lever  86  may no longer be engaged to the channel of the slat. Once the lever  86  have been articulated, a user may slide the block  62  along the channel of the slat via the tab  88  of the lever  86 , a tab  66  of the block  62 , or both. In doing so, the user may disconnect the extension  64  from the cable, thereby releasing the slats of the tonneau cover from the drive system. 
     Additionally, the disconnect may be moved to one or more designated positions along the channel (see  FIG.  4   ) in which the projections  92  of the tab  88  engage the channel. Upon releasing the lever  86 , a user may move the disconnect  60  to a desired position, whereby the lever  86  may automatically be biased towards the channel due to a biasing member  80  connected between the block  62  and the lever  88 . The biasing member  80  may include a helical portion  82  extending around a pin  84 . The pin  84  may extend between apertures  72  of the block  62  and barrels  90  of the lever  88  so that the lever  88  is biased away from - or outwardly from - the cavity of the block  62 . As a result, the projections may be biased away from the block  62  once the projections  92  reach the designated location along the channel of the slat (i.e., once the projections  92  reach notches along the channel of the slat). 
       FIG.  9    illustrates a side view of the disconnect  60  shown in  FIG.  8   . The disconnect  60  includes a block  62  having one or more bulbs  78  extending along a length of the block  62  near an upper and lower surface of the block  62 . As such, the bulbs  78  may engage or otherwise contact a channel of the slat. As discussed above, a lever  86  may be biased relative to the block  62  by a biasing member positioned within a cavity of the block  62  and secured to a pin  84  extending between apertures  72  of the block  62 . Due to the nature of the biasing member, a tab  88  of the lever  86  may be moved upwardly toward the block  62  until projections  92  along the tab  88  of the lever  86  are received within an opening  68  of the block  62 . However, once the tab  88  of the lever  86  is released, the level  86  may be biased away from the block  62  to engage the channel of the slat. Thus, it may be gleaned from the present teachings that the disconnect  60  may be engaged and/or released from the channel of the slat due to articulation of the lever  86  relative to the block  62 . Similarly, when the lever  86  is disengaged from the channel of the slat, the disconnect  60  may be moved via a tab  66  of the block  62  to release the extension  64  of the block  62  from the drive system of the tonneau cover. 
       FIG.  10    illustrates a bottom view of the disconnect  60  shown in  FIGS.  8  and  9   . As discussed above, the disconnect  60  includes a lever  86  positioned within a cavity  74  of a block  62 . The lever  86  may be articulated relative to the block  62  due a to a biasing member  80  positioned therebetween. The biasing member  80  may include a helical portion  82  wrapped around a pin  84  to maintain a position of the biasing member  80 . Similarly, barrels  90  of the lever  86  may receive the pin  84  to allow for pivoting of the lever  86  relative to the block  62 . 
     Upon pivoting, a tab  88  of the lever  86  may extend upward into openings  68  of the block  62 , thereby releasing projections  92  along the tab  88  from the channel of the slat. Once the projections  92  are released, the disconnect  60  may be guided along the channel of the slat by a plurality of bulbs  78  of the block  62  due to a user moving the disconnect  60  via a tab  66  of the block  62 . As a result, an extension  64  of the block  62  may be disconnected from a drive system of the tonneau cover (e.g., a cable or extension thereof). 
       FIG.  11    illustrates an exploded view of a disconnect  60  in accordance with the present teachings. The disconnect  60  may include a block  62 . The block  62  may include a plurality of bulbs  78  positioned near corners of the block  62  and extending at least partially along a length of the block  62 . The block may further include an extension  62  extending away from a cavity  74  of the block  62  and may be adapted to engage a drive system of the tonneau cover. Additionally, the block  62  may include a tab  66  positioned near a terminal end of the block  62  that opposed an end having the extension  62 . 
     A pin  84  may be positioned within the cavity  74  of the block  62  so that the pin  84  extends between opposing apertures  72  located on side walls of the block  62 . The apertures  72  may be substantially coaxial or aligned to receive the pin  84 . A helical portion  82  of a biasing member  80  may be positioned around the pin  84  to locate the biasing member  80  within the cavity  74  of the block  62 . Similarly, the pin  84  may extend through a plurality of barrels  90  located near an end of a lever  86  so that the lever  86  is at least partially positioned within the cavity  74  of the block  62 . The biasing member  80  may also be at least partially positioned between the lever  86  and the cavity  74  of the block to bias a tab  88  of the lever  76  away from the block  62 . As a result, a user may move the tab  88  upwards so that projections  92  of the tab  88  are received by openings  68  of the block  62  to decrease an overall height of the disconnect  60 , to release the lever  86  from connection to a channel of a slat, or both. However, the biasing member  80  may thus beneficially bias the lever  86  away from block  62  once a user releases the tab  88  of the lever  86 .

     The explanations and illustrations presented herein are intended to acquaint others skilled in the art with the invention, its principles, and its practical application. The above description is intended to be illustrative and not restrictive. Those skilled in the art may adapt and apply the invention in its numerous forms, as may be best suited to the requirements of a particular use. 
     Accordingly, the specific embodiments of the present invention as set forth are not intended as being exhaustive or limiting of the teachings. The scope of the teachings should, therefore, be determined not with reference to this description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The omission in the following claims of any aspect of subject matter that is disclosed herein is not a disclaimer of such subject matter, nor should it be regarded that the inventors did not consider such subject matter to be part of the disclosed inventive subject matter. 
     Plural elements or steps can be provided by a single integrated element or step. Alternatively, a single element or step might be divided into separate plural elements or steps. 
     The disclosure of “a” or “one” to describe an element or step is not intended to foreclose additional elements or steps. 
     While the terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings. 
     Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature’s relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. 
     Unless otherwise stated, a teaching with the term “about” or “approximately” in combination with a numerical amount encompasses a teaching of the recited amount, as well as approximations of that recited amount. By way of example, a teaching of “about 100” encompasses a teaching of 100 +/-  15 . 
     The disclosures of all articles and references, including patent applications and publications, are incorporated by reference in their entirety for all purposes. Other combinations are also possible as will be gleaned from the following claims, which are also hereby incorporated by reference in their entirety into this written description.
