Patent attributes
Novel techniques are provided for implementing a tonneau cover system. A tonneau cover system might include a first side rail configured to be coupled to a side wall of a bed of a truck, a first connection plate attached to and extending from the first side rail, a second connection plate, an extension plate extending from and attached to the second connection plate, and a cover for covering the bed of the truck and coupled to the extension plate. The first connection plate might include a recess on a bottom surface of the first connection plate. The second connection plate might include a first protrusion mirroring the first recess on the first connection plate. The first protrusion of the second connection plate might removably engage with the recess on the bottom surface of the first connection plate to couple the second connection plate to the first connection plate.
