Abstract: A hardtop shell is provided for vehicles having a variety of vehicle body styles, including all sport utility vehicles (SUV), trucks and crossovers. The hardtop shell follows the top frame of the vehicle/OEM roll cage, allowing for much more open-air space, when removing modular portions of the hardtop. The hardtop shell follows the top frame of the vehicle. The hardtop shell also can be mainly fabricated out of metal. The hardtop shell comprises a main outer frame that mates to the body and frame of the vehicle, and may also comprise modular and removable additional components such as roof panels, a rear door and gull wings. The main frame mates to the body or frame of the vehicle with a plurality of bolts, nuts, rivnuts, gaskets, seals, compression latches and other similar hardware or methods.

Abstract: A bead and interconnecting bead structure for use in a flexible arm assembly having improved interface characteristics allowing for simple, quiet adjustment of the structure in three dimensions, while simultaneously increasing the weight of object the arm assembly can support. The interface characteristics are improved by utilizing two different materials at the area of contact between two adjacent beads.
