A tonneau cover comprising: (a) a plurality of panels; (b) one or more hinges between each panel of the plurality of panels so that the plurality of panels are rotatably connected together, wherein some or all of the one or more hinges include: (i) a plurality of expansion links that are movably interconnected together, some of the plurality of expansion links including: (1) one or more expansion projections; (2) one or more pockets that receive all or a portion of the one or more expansion projections from an adjacent one of the plurality of expansion links; and (3) one or more expansion stops that restricts movement of the one or more expansion projections from the adjacent one of plurality of the expansion links that extend within the one or more pockets; wherein the one or more hinges rotate so that the one or more hinges form of angle of about 90 degrees or more and about 225 degrees or less.

Provided are a folding device, a compartment cover, and an automobile, belonging to the technical field of automobile accessories. The automobile includes the compartment cover. The compartment cover includes a folding device and plates disposed on two sides of the folding device. The folding device includes a pivot profile, a connection profile, and a rolling element. The connection profile is connected to each of two sides of the pivot profile. One of the pivot profile or the connection profile is provided with an accommodation recess. The other one of the pivot profile or the connection profile is provided with an engaging portion. The engaging portion rotates in the accommodation recess. The rolling element is rotatably disposed between the inner wall of the accommodation recess and the engaging portion.

A retractable truck bed cover having an array of parallel aluminum slats joined together by connective hinges including leading and trailing edge configuration for improving the security of the cover by covering and concealing the seam between adjacent slats while improving the connective hinge's resistance to the effects of aging and/or exposure to temperature fluctuations. The truck bed cover connective hinge slat is designed to be in an array of discrete slats, which are joined to one another by means of joiner members secured at each end to slat end caps. The distal ends of the joiner members are attached to slat end caps at the distal ends of the slats, thereby preventing the joiner members from shrinking in relationship to the slats due to aging and I or exposure to temperature fluctuations.

A tonneau cover comprising: (a) a first panel and a second panel; (b) a hinge located between and connecting the first panel and the second panel; and (c) a cover extending over all or a portion of the first panel, the second panel, or both, and the hinge so that, when the first panel or the second panel rotates about the hinge, the cover forms a portion of the hinge and maintains the integrity of the hinge.

A tonneau cover that includes a first panel, a second panel, a hinge between the first panel and the second panel, and a torsion element between the first panel and the second panel. The torsion element applies an urging force onto one or both of the first panel and the second panel during movement of the first panel and/or the second panel about the hinge.

A nestable covering assembly for a bed of a truck includes a pair of rails, each of which comprises a plurality of channels. Each rail is mountable to a respective opposed sidewall of a bed of a truck so that the rail extends from proximate to a front of the bed to proximate to a rear of the bed. A plurality of nested panels is slidably engaged to the rails so that each nested panel extends between the rails. Respective nested panels are operationally engaged to associated channels so that the respective nested panels are selectively slidable between a nested configuration and an extended configuration. In the extended configuration, the plurality of nested panels covers the bed of the truck and protects contents of the bed.

A retractable pickup truck box cover system includes a pivot joint with improved strength, durability, and manufacturability between panels of a panel assembly of the cover system. A sealing system between the panels and along ends of the panel assembly provides improved weather resistance to the cover system. A lateral support system provides resistance to binding loads when opening and closing the panel assembly. The lateral support system may also aid installation of the cover system. A ramp adjustment system allows fine tuning of the ramps that guide folding and unfolding of the panel assembly. An improved locking system and the pivot joints allow more compact storage of the panel assembly. The improved locking system includes lock rods that engage rails of the cover system. Connecting structures connect adjacent panel pairs when the cover system is deployed and do not connect the adjacent panels when the cover system is stowed. A seal of the sealing system includes angled and/or transvers ribs to support a bulb of the seal when pivotally scrubbing against the panels. The seal includes a plurality of interior portions that selectively compress and bulge between the panels. The seal includes a coating that may provide stiffness, wear resistance, hardness, and/or reduced friction. A clamping system allows installation of the cover system without drilling holes and includes built-in fixturing for locating clamps and thereby locating the cover system on the pickup truck box.

A tonneau cover that includes a first panel, a second panel, a hinge between the first panel and the second panel, and a torsion element between the first panel and the second panel. The torsion element applies an urging force onto one or both of the first panel and the second panel during movement of the first panel and/or the second panel about the hinge.

A tonneau cover comprising: (a) a plurality of panels; (b) one or more hinges between each panel of the plurality of panels so that the plurality of panels are rotatably connected together, wherein some or all of the one or more hinges include: (i) a plurality of expansion links that are movably interconnected together, some of the plurality of expansion links including: (1) one or more expansion projections; (2) one or more pockets that receive all or a portion of the one or more expansion projections from an adjacent one of the plurality of expansion links; and (3) one or more expansion stops that restricts movement of the one or more expansion projections from the adjacent one of plurality of the expansion links that extend within the one or more pockets; wherein the one or more hinges rotate so that the one or more hinges form of angle of about 90 degrees or more and about 225 degrees or less.

A tonneau cover comprising: (a) one or more panels pivotally connected to one or more additional panels via hinge portions; and (b) hinges having a plurality of engaging features, the hinges being positioned within the hinge portions so that the plurality of engaging features are secured within channels of the panels to connect the panels, the hinges further including a fin that projects from the hinges and seals a gap between the connected panels.
