Abstract: The present disclosure provides a fastening system for using in a flexible tonneau cover system. In one aspect, the fastening system comprises a corner member connected to a end rail, and a connecting member connected to an side rail. The corner member comprises a positioning tab that is received in a positioning groove formed on the connecting member. In another aspect, the fastening system comprise a corner member with a recess portion. When the corner member is connected with a side rail at an end thereof, the recess portion and the end of side rail form an accommodating groove. In another aspect, the fastening system comprise a fastening element coupled to an elongated slat. A reinforce tab is coupled with the fastening element, and wraps over an end of the elongated slat to extend at a bottom surface of the elongated slat.

Abstract: The present invention is directed a tonneau system. More specifically, embodiments of the present invention provide a tonneau system, which includes multiple frame bars interconnected by latches. At least one of latches includes a rod that is operably coupled to its main portion, which includes an opening to accommodate the rod. The rod attaches to a hook jaw that includes two openings for attaching to the truck frame. There are other embodiments as well.
