Abstract

Particular embodiments may provide a tonneau system for a vehicle. The tonneau system may be movable between an extended configuration and a retracted configuration. The tonneau system may include a cover, a beam, and rails. The cover may have two side edges and a tail edge, the beam may be coupled to the tail edge of the cover, and the rails may be coupled to the side edges of the cover. In some embodiments, the beam and the rails bi-directionally tension the cover when the tonneau system is in the extended configuration.

First claim

The invention claimed is:

1 . A tonneau system for a vehicle, the tonneau system movable between an extended configuration and a retracted configuration, the tonneau system comprising:
a cover comprising two side edges, a lip along one of the side edges, and a tail edge; a beam coupled to the tail edge of the cover; a rail coupled to the lip of the cover; and a mechanism coupled to the rail and configured to move the rail to cause the lip to move outward to tension the cover in a direction parallel to the tail edge when the tonneau system is in the extended configuration.

2 . The system of claim 1 , wherein the beam and the rail bi-directionally tension the cover by tensioning in a direction parallel to the side edges and in the direction parallel to the tail edge.

3 . The system of claim 2 , wherein the beam and the rail bi-directionally tension the cover by first tensioning the cover in the direction parallel to the side edges and then simultaneously further tensioning the cover in the direction parallel to the side edges and tensioning the cover in the direction parallel to the tail edge.

4 . The system of claim 1 , wherein the rail interacts with the lip to tension the cover in the direction parallel to the tail edge.

5 . The system of claim 4 , wherein the mechanism comprises a cam coupled to the beam such that turning the cam turns the rail, thereby moving the lip away from a center of the cover.

6 . The system of claim 1 , further comprising a rod coupled to the beam such that pulling the rod moves the beam in a direction parallel to the side edges and wherein rotating the rod relative to the beam causes the rail to tension the cover.

7 . The system of claim 6 , wherein the rail is a first rail and the lip is a first lip along a first side edge of the two side edges, the system further comprising:
a second lip along a second side edge of the two side edges; a first linking element connecting the rod to the first rail; and a second linking element coupled to the rod and connecting the rod to a second rail, wherein rotating the rod relative to the beam causes the first linking element to move toward the first rail to tension the cover and the second linking element to move toward the second rail to tension the cover and wherein the mechanism comprises the first linking element.

8 . The system of claim 2 , further comprising a rib to support the cover, wherein a force acts on the rib when the beam and the rail bi-directionally tension the cover, the force causing the rib to bow.

9 . The system of claim 1 , wherein the rail comprises a track, and the system comprises slugs attached to the lip of the cover and configured to sit in the track.

10 . The system of claim 1 , wherein, in the extended configuration, the cover overlaps an area corresponding to an open cargo volume of the vehicle.

11 . The system of claim 1 , wherein;
the beam comprises a straight middle portion and angled end portions; the rail is a first rail and the system further comprises a second rail; and the end portions are proximal to the first and second rails.

12 . The system of claim 11 , wherein the mechanism comprises a plunger and the beam is coupled to the plunger at an end portion and the plunger contacts the rail.

13 . A method of closing a tonneau system, the system comprising a cover, a rail coupled to a side edge of the cover, and a mechanism coupled to the rail, the method comprising:
moving the tonneau system from a retracted configuration to an extended configuration; and moving the rail, using the mechanism, to cause the side edge of the cover to move outward to tension the cover in a direction parallel to a tail edge of the cover when in the extended configuration.

14 . The method of claim 13 , wherein;
the tonneau system comprises a beam; the beam is coupled to the tail edge of the cover; and the beam and the rail cooperate to bi-directionally tension the cover.

15 . The method of claim 14 , wherein the beam and the rail cooperate to bi-directionally tension the cover by tensioning the cover in a direction parallel to the side edge and in a direction parallel to the tail edge.

16 . The method of claim 15 , wherein the beam and rail cooperate to bi-directionally tension the cover by first tensioning the cover in the direction parallel to the side edge and then simultaneously further tensioning the cover in the direction parallel to the side edge and tensioning the cover in the direction parallel to the tail edge.

17 . The method of claim 14 , wherein:
the mechanism comprises a rod coupled to the beam; the method further comprises pulling the rod to move the beam in a direction parallel to the side edges; and rotating the rod relative to the beam causes the rail to move.

18 . A vehicle comprising
a cargo area; and a tonneau system comprising an extended configuration that overlaps the cargo area and a retracted configuration that overlaps less of the cargo area than the extended configuration, wherein the tonneau system comprises:
a cover comprising two side edges, a lip along one of the side edges, and a tail edge;
a beam coupled to the tail edge of the cover;
a rail coupled to the lip of the cover; and
a mechanism coupled to the rail and configured to move the rail to cause the lip to move outward to tension the cover in a direction parallel to the tail edge when the tonneau system is in the extended configuration.

19 . The vehicle of claim 18 , wherein the vehicle comprises a wall adjacent to the cargo area and wherein the rail is coupled to the wall.

20 . The vehicle of claim 18 , wherein a trim of the vehicle overhangs a point of interaction between the cover and a side wall of the cargo area.
