Abstract: A cushion subassembly includes a support, a cushion of non-woven polymeric (PET) or PETE fibers with a formed edge that wraps over an edge of the support, and an upholstery sock pulled onto and covering the support and the cushion. The formed edge has sufficient mechanical structure to retain the cushion on the support as the upholstery sock is pulled onto the support. A back support shell supports the cushion assembly, and has first fasteners that engage in a first direction and second fasteners that prevent disengagement. The cushion assembly is stressed during assembly, especially at corners, but is thermally stress-relieved after assembly to relax the polymeric fibers and the upholstery sock to a state of minimized balanced tension. The back support shell includes a shallow depression on its face. The cushion fills the depression sufficient to eliminate loose fabric but provides a same force deflection curve across its shape.

Abstract: A fifth wheel mounting assembly for mounting a fifth wheel hitch plate to a frame of a tractor that includes a pair of first support members adapted to be fixedly coupled to a pair of rails of a tractor, and each having a plurality of first apertures, and a pair of first mounting brackets each including a plurality of apertures that receive mounting hardware therein, wherein the mounting hardware extends through the plurality of apertures of the first mounting bracket and through the plurality of first apertures of the support members, thereby fixedly coupling the mounting brackets with the support members. Each mounting bracket further includes an inwardly exposed aperture adapted to receive a mounting pin therein for pivotally coupling a fifth wheel hitch plate to the mounting brackets, and a recess.

Abstract: A hydrofoil for mounting on the lower unit of a marine outboard engine/marine outdrive which improves the performance and stability of a boat driven by the lower unit. Each hydrofoil includes an upwardly angled wing segment and a wingtip fin at the outer end of the wing segment. The hydrofoils are preferably mounted in a pair on the lower unit and form a V-shaped assembly. Alternately, the hydrofoils may be formed as a single unit in which they are joined near their trailing edges. When mounted on the lower unit on a boat with a V-shaped hull bottom, the hydrofoil assembly generally matches the hull bottom shape to lower drag and water resistance during operation and to prevent interference with the forks of a fork lift truck when the boat is lifted.

Abstract: A low silhouette cargo bay cover for pickup trucks and the like includes an angle member mounted on the cargo bay sides equipped with a flexible gasket to form a seal with the cover. The cover has a special narrow panel adjacent the cab to make it possible to more completely expose the cargo area of the turck and improved seal means at each of the hinges to more effectively exclude moisture.
