The panels 102, 104, 106, etc. may be rolled into a roll as illustrated in Fig. 2B. In some configurations, the panels 102, 104, 106, etc. may be rolled and stored in a canister. The canister may be located anywhere in the vehicle 10 or the cargo area 12, for example, near the front wall 18 of the cargo area adjacent to the passenger area 12.

[0039] Fig. 3 A illustrates a tonneau cover 100. The tonneau cover 100 comprises at least two panels. In this example, the tonneau cover 100 comprises panels 102, 104, and 106. Each of the panels 102, 104, 106 comprise a top side 108 and an opposing bottom side 110. In vehicle position, the top side 108 is configured to face outwardly when the tonneau cover is in a closed configuration. In vehicle position, the opposing bottom side 110 is configured to face the floor 22 of the cargo area 12 (Figs. 1 A, 2A) at least when the tonneau cover is in a closed position.

[0040] The tonneau cover 100 comprises a carrier 112. The carrier 112 is applied onto the top side 108 of the at least two panels 102, 104, 106. The carrier 112 is configured to connect the at least two panels 102, 104, 106 together. The carrier 112 is configured to provide a hinge 114 between two adjacent panels 102 and 104, 104 and 106, etc.

[0041] The panels 102, 104, 106 are arranged so that a gap 116 is defined between opposing or adjacent edges 118 of the panels 102, 104, 106. In other words, two or more adjacent panels 102, 104 and 104, 106 are spaced spart from one another and are not connected to one another, except via the carrier 112. The carrier 112 is configured to restrict or prevent fluid and / or debris from passing through the gap 116 between two or more adjacent panels.PCT / US24 / 47367 19 September 2024 (19.09.2024)Filed via USPTO. Gov. on September 19, 2024Docket No.: 2021A.030WO (8877357)

[0042] Figs. 3B and 3C illustrate one of the panels 106 being folded or rotated about the hinge 114 of the carrier 112.

[0043] Figs. 4A and 4B illustrate a tonneau cover 100. The tonneau cover 100 may be substantially the same as the one illustrated and described above at Fig. 3A; therefore, like elements will not be described again. The tonneau cover 100 comprises a second carrier 120 that is provided in between the carrier 112 and the top surface 108 of the at least two panels 102, 104, 106. The second carrier 120 may function to provide a connection between the panels 102, 104, 106 before the carrier 112 is applied. The second carrier 120 may function to prevent the carrier 112 from dripping or falling into the gap 116 before the carrier 112 is applied. The second carrier 120 may have the same material and / or functional characteristics as the first carrier 112. The second carrier 120 may have different material and / or functional characteristics as the first carrier 112.

[0044] In Fig. 4A, the second carrier 120 extend along an entirety of the top surfaces 108 of the panels 102, 104, 106.

[0045] In Fig. 4B, the second carrier 120 extends along the top surfaces 108 only in a region of the 116 defined between the adjacent panels 102, 104 and 104, 106.

[0046] Figs. 5A-5D illustrate an exemplary fixture 200 for making or assembling the tonneau cover 100. The fixture 200 comprises a plurality of bays 202, 204, 206. The bays 202, 204, 206 are defined between a pair of walls or separators 208. Each of the bays 202, 204, 206 are sized and configured to receive a respective panel 102, 104, 106. The number of bays of the fixture 200 will correspond at least to the number of panels of the tonneau cover.

[0047] A method 300 of making the tonneau cover 100 according to these teachings may include one or more of the following steps.

[0048] The method 300 may include a step of inserting 302 a panel into a respective one of the bays of the fixture. For example, panel 102 may be inserted, placed, or received into bay 202, panel 104 may be inserted, placed, or received into bay 204, panel 106 may be inserted, placed, or received into bay 206, etc.

[0049] The method 300 may include a step of applying 304 the carrier 112 onto the top surfaces of the panels. For example, the carrier 112 may be applied, sprayed, provided, adhered, onto the top surfaces 108 of the panels 102, 104, 106. The separators 208 may be configured to maintain the carrier 112 within the footprint of the top surface of the panels. The separators 208PCT / US24 / 47367 19 September 2024 (19.09.2024)Filed via USPTO. Gov. on September 19, 2024Docket No.: 2021A.030WO (8877357) may be configured to restrict or prevent the carrier 112 from falling or dripping into the gap 116 defined between adjacent panels.

[0050] In the event that the tonneau cover is to have a second carrier between the top surfaces of the panel and the carrier, the method may include a step of applying a second carrier onto the desired region of the top surfaces of the panels (See e.g., Fig. 4A and 4B, carrier 120).

[0051] In some configurations, a gap may be defined between an edge of some panels and a separator. This may allow for the carrier 112 to also cover a side edge of one or more panels. For example, referring to Fig. 5C, a gap 112 may be defined between an edge of the panels 102, 106, which may be the outer panels, so that the carrier 112 also coves the side edges of the panels. This may provide for a more finished look.

[0052] The method may include a step of removing 306 the tonneau cover 100 from the fixture 200.
