BACKGROUND

Numerous types of truck bed covers can be arranged over the utility or cargo bed portion of a ute or pickup truck to secure and protect the bed including cargo items disposed therein. In particular, roll top covers generally include a motorized or mechanical drive system for operably covering and uncovering the top of an open cargo bed, truck box or the like by way of an extendable and retractable slat assembly.

Prior art roll top covers can suffer from a number of drawbacks. By way of example, such roll top covers may not be fully weather resistant and/or impervious to moisture and dust. Additionally, the frictional forces that are produced between the drive chain and the associated drive chain track or rail during operation (i.e., opening and/or closing) of the roll top cover can be significant so as to make closing and/or opening difficult for a user. Further to this, movement or vibration of the slats of the roll top cover can result in the production of undesirable noise during operation of the associated vehicle.

Accordingly, an improved roll top cover that overcomes one or more of the above disadvantages is required.
