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.

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.

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. The alignment wedge also includes a tapered interface surface extending in a plane substantially perpendicular to the arcuate surface, the interface surface being positioned to contact an opposing surface of the door or door jamb when the door is in the closed position to align the door in a fore/aft orientation with respect to the door jamb. An improved method for simultaneously aligning the door and the door jamb in top/bottom and fore/aft orientations is also provided.

Door alignment assembly and method

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.

Articulating vent window assembly

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.

Door check and stop

A truck cab including entry doors on either side, a fender below and spaced in front of each entry door, and a fuel tank below and spaced behind each entry door is disclosed herein. The cab also includes aerodynamic step assembly which is located on each side of the cab below the entry door on that side and which contains a readily accessible tool or battery box. This box and the steps leading to the entry door are no wider than the door itself and therefore are spaced from the adjacent fender and fuel tank. However, aerodynamically shaped panels form part of the overall assembly for closing these spaces.

Aerodynamically streamlined step assembly for a truck

A vehicle of the type having a manual transmission is disclosed herein. The manual transmission includes a clutch, a clutch pedal and a linkage assembly interconnecting the clutch with the pedal and requires that the driver of the vehicle depress the clutch pedal in order to disengage the clutch. There is also disclosed herein an arrangement for assisting the driver in disengaging the clutch when the clutch pedal is depressed. This arrangement includes a power assist device, a source of power for driving the device, and a valve assembly including a valve and mounting components interconnecting the valve with the transmission's linkage assembly such that the manual depression of the pedal by the driver automatically acts on the valve to cause the latter to connect the power assist device to its source of power in order to drive the device and therefore aid the driver in disengaging the clutch.
