Abstract: A door assembly for a truck including an outer door assembly, a reinforcement panel, and a door cover panel. The outer door assembly is made of a lightweight aluminum for weight savings, the reinforcement panel is made of a high strength steel to provide required strength and the added benefit of subassembly.

Abstract: A device for limiting the extent to which a vehicle door, hinge-mounted to the cab jamb along one side thereof for movement between a closed position and an open position within the surrounding jamb, will flex as a result of an individual hanging from or otherwise pulling downward on a mirror assembly externally mounted to said door.

Abstract: An alignment assembly for aligning a door in a door jamb as the door is rotated into a closed position is disclosed. The door alignment assembly includes at least two door alignment components mounted in proximity to one another generally opposite the pivot axis of the door, one alignment component mounted on the door and the other alignment component mounted on the door jamb. The door alignment components include an alignment wedge having an arcuate surface and an alignment assistor having an angled lateral edge positioned to contact the arcuate surface of the alignment wedge along a substantially point contact to align the door in a top/bottom orientation in the door jamb.

Abstract: An articulating vent window assembly is provided wherein a vent window is pivotally mounted with respect to a sealing element for adjustment between a closed and an open position. A pivot mechanism is mounted near a peripheral edge of the vent window, providing articulation of the vent window around a pivot axis in proximity and substantially parallel to one of the peripheral edges of the vent window. The articulating vent window is adjustable between a closed position and at least one discrete open position by engagement of the pivot mechanism with spaced grooves provided in a corresponding detent member. A method for pivotally mounting a vent window in a vent window sealing element is also disclosed.

Abstract: A hinge assembly for a vehicle is provided having an internal passageway defined by mated slotted portions of the hinge and the door jamb, check assembly, mounted on the hinge and having a specifically configured free end extending through the passageway, and detent arrangement, mounted on the interior of the door jamb for engagement with the specifically configured free end of the check assembly to restrain rotation of the door in a primary intermediate open position. The specifically configured free end of the check assembly and the detent arrangement cooperated with one another so as to alternatively restrain rotation of the door in the primary intermediate open position and a less open secondary intermediate open position, and the check assembly is formed for releasable engagement with the detent arrangement to permit free rotation of the door to a fully open position.
