Patent attributes
A tonneau system for a cargo box of a vehicle having a support frame connectable to the cargo box. A cover spans the support frame and is positionable between a tensioned position and an untensioned position. A pivot block is mounted to the support frame, while the cover is coupled to a front bracket member. The front bracket member carries the cover and pivotally engages the pivot block such that the front bracket member rotates between a raised position and a lowered position. The front bracket member can be automatically locked in the lowered position. The front bracket member can also be unlocked and rotated to a raised position. In the raised position, bracket member may be removed from the support frame and positioned to provide temporary access to the cargo box without unsecuring the remaining portions of the tonneau cover. A bow member couples the cover along a cross vehicle direction. The bow member or other member can operate to tension the cover in the cross vehicle direction.
