A vehicle door assembly includes an outer panel and an inner panel. The outer panel has an inboard surface and an outboard surface. A door handle receiving area is disposed in the outer door panel and is configured to receive a door handle. The inner panel has an inboard surface and an outboard surface. The inner panel is connected to the outer panel. A first stiffener member is disposed beneath the door handle receiving area. A second stiffener member is disposed above the door handle receiving area.

The present disclosure relates to a vehicle door coupling device, and more specifically, to a vehicle door coupling device for mechanically coupling together a first member having a first hole and a second member having a second hole at a position corresponding to the first hole. The vehicle door coupling device includes: a stopper configured to support the first member; and a shaft including a crossbar configured to support the second member and couple the second member to the first member when the shaft is rotated to a final coupling position, and a hook portion configured to cause the shaft to be caught on the first member in a temporary coupling position, the shaft being connected to support the stopper and the crossbar, wherein the shaft is shaped such that the shaft is inserted into the first hole of the first member and the second hole of the second member and rotatably passes therethrough, and an material for airtight is provided on the shaft to maintain airtightness between the shaft and the first hole of the first member in the final coupling position.

A door structure comprises a door body, a window glass having a substantially rectangular shape, and a window regulator. The door body has a sash being provided to the door body before the window glass is connected to the carrier plate at one side of the door body in a front and rear direction of the vehicle, and the sash has a groove, in which only one edge of the window glass is inserted, and the door structure further includes a separating member configured to separate the window glass from the sliding face of the guide rail.

A convertible vehicle door includes a high visibility exterior off-road frame door including a hinge assembly to hingedly couple to a vehicle body, and an inner on-road panel configured to releasably couple to the high visibility exterior off-road frame door inboard thereof. The convertible vehicle door is convertible between an on-road door configuration where the inner on-road panel is coupled to the high visibility exterior off-road frame door, and an off-road door configuration where the inner on-road panel is detached from the high visibility exterior off-road frame door.

A motor vehicle door having a frame defining a window opening, and a window lift system having a first guide rail, a first sliding piece guided on the first guide rail, a second guide rail, a second sliding piece guided on the second guide rail, a cable drum and a drive cable driven by the cable drum and coupled to the sliding pieces, the drive cable guided in a Bowden cable sheath between an upper end region of the second guide rail and a connection region located between an upper end region of the first guide rail and a lower end region of the first guide rail. The Bowden cable sheath fastened in the upper end region of the second guide rail and in the connection region of the first guide rail.

The vehicle door assembly includes an outer panel which has a rocker sill area and a beltline area. A reinforcement member, which is made of one or more pieces, is attached with the outer panel along at least a portion of an outer periphery of the outer panel. The door assembly further includes a module which is made as a single integral piece and is fixedly attached with the reinforcement member. The module has an inner beltline reinforcement and supports a pair of window channels and a window regulator for controllably raising and lowering a window between an open position and a closed position.

A door assembly and an assembly method for a door assembly with a door skin, a support component and an interior trim component, the support component is fastened to the door skin by at least one mounting component. The at least one mounting component is also used for mounting the interior trim component since a head section of the mounting component projects from the support component and the interior trim component is mounted on the head section.

A method of assembling at least two types of vehicles with different powertrain requirements on the same assembly line is provided. The method includes assembling a first structural body component for a first vehicle type including a first powertrain requirement. The first structural body component comprises a first structural core surrounded by a first fiber reinforced material having a first thickness. The first structural body component has a first external geometry. The method includes assembling a second structural body component for a second vehicle type that has a second powertrain requirement different from the first powertrain requirement. The second structural body component comprises a second structural core surrounded by a second fiber reinforced material having a second thickness different from the first thickness. The second structural body component has a second external geometry that is the same in shape and dimension as the first external geometry.

A door of a vehicle may include a first door module forming a door skeleton; a second door module coupled with the first door module and forming a door window; and a door frame coupled to the first door module and engaged with the second door module; wherein the second door module may include a relatively lightweight material as compared to the first door module, reducing weight and cost of the door for the vehicle.

A keyfob has an electronic controller, a plurality of command inputs, a keyfob antenna and a feedback device. The plurality of command inputs, the keyfob antenna and the feedback device are in electronic communication with the controller. The controller is configured to send signals to a vehicle door lock system in response to operation one or more of the plurality of command inputs that instruct the vehicle door lock system to switch at least one door between a locked state and an unlocked state. The controller is further configured to enter a diagnostic mode in response to a predetermined operation of the plurality of command inputs such that in the diagnostic mode the keyfob operates as a diagnostic tool that detects an operating state of at least one of the keyfob and the vehicle door lock system.
