Abstract: A tonneau cover assembly for a pick-up truck includes a cover that is manufactured by sandwiching a rectangular metal frame between an inner panel and an outer panel. The metal frame provides stability to the cover assembly as well as providing attachment points for the outer components of the tonneau cover assembly. The cover is pivotally attached to a pair of side rails using a four-bar linkage hinge, the four-bar linkage hinge causes the cover to move up from the pick-up box and away from the pick-up cab when the cover is opened. This up and away movement allows the cover to be positioned closer to the cab without causing interference between the cab and the cover when it pivots to its open position.
