Abstract: A convertible cargo bed cover can function as both a tonneau cover and a cargo bed cap. The cover is raised by motorized elements to be substantially aligned with a roof of a passenger cabin of the vehicle. Side and rear window panels stored inside the cover can be installed to transform the cover to a cap to enlarge available enclosed cargo space. Rear pillars are installed at the rear corners of the tonneau cover in its raised position to complete the installation.

Abstract: A rear seat assembly of a passenger cabin of a pick-up truck includes a rear seat cushion and a rear seat back, each rotatable such that a bottom surface of the rotated rear seat back can rest upon a rear end of the rotated seat cushion to provide a storage space beneath the rotated seat back and between the rotated seat cushion and a rear wall of the passenger cabin. The cargo bed of the truck may be extended into the storage space by providing an access door thereto in a front wall of the cargo bed in communication with a corresponding opening in the rear wall of the passenger cabin.
