A vehicle door includes a door panel slidably operable between a secured position within a door aperture and a staging position partially distal from the door aperture. A latch is engaged with a striker path during operation of the door panel between the secured and staging positions, and is selectively disengaged from the striker path to define open and closed positions of the door panel when the door panel is in the staging position.

A device for operating opposite sliding doors of a vehicle includes a center rail mounted at a center inside a door and formed in a curved shape so that the door moves to the outside of a vehicle interior of the vehicle when the door is opened. A center roller is mounted on the vehicle body so as to correspond to the center rail. The center roller is configured to move the center rail by being coupled to the center rail when the door is opened or closed as a center bearing unit formed at one side of the center roller is seated on the center rail. The center roller has a center shaft formed at a position spaced apart from the center bearing unit such that the center shaft can rotate the center roller.

An opposed type sliding door device includes a center rail mounted on a center of a door in a longitudinal direction of the door. A center roller is mounted on a vehicle body so that the center rail moves while supporting the center rail. A lower rail is mounted on a lower portion of the vehicle body in a straight line in the longitudinal direction of the vehicle body. A lower roller is mounted on the door and moves along the lower rail to pivot the door toward the outside. The lower roller further includes a pinion gear which engages in a rack gear mounted on a lower portion of the lower rail, a planetary gear reducer coupled to an upper portion of the pinion gear, and a swing bracket moving the door toward the outside with rotation of the pinion gear.

A vehicle includes a support structure. The vehicle also includes a side door operable to move relative to the support structure between an open position and a closed position. In the open position of the side door, access to a vehicle interior of the vehicle is provided. In the closed position of the side door, the side door extends across a longitudinal centerline of the vehicle. The vehicle further includes a plurality of pivot members, each pivotably coupled to the support structure at a first end and pivotably coupled to the side door at a second end. The side door is movable between the open and closed positions via pivotal movement of each of the plurality of pivot members relative to the support structure and pivotal movement of the side door relative to each of the plurality of pivot members.

An embodiment is a side sill assembly for a vehicle including a side sill inner part coupled to a floor of a vehicle and extending in a longitudinal direction of the vehicle, the side sill inner part having an accommodation space formed by recessing a partial section toward an inside of the vehicle and configured such that a link mechanism connected to a door of the vehicle is rotatably accommodated in the accommodation space, a side sill center part having a cross-section extending from the side sill inner part to an outside of the vehicle, the side sill center part extending in the longitudinal direction of the vehicle along the side sill inner part, and a side sill cover configured to define a closed cross-section by connecting the side sill center part and an upper portion of the side sill inner part in a section except for the accommodation space.

A vehicle door includes a door panel slidably operable between a secured position within a door aperture and a staging position partially distal from the door aperture. A latch is engaged with a striker path during operation of the door panel between the secured and staging positions, and is selectively disengaged from the striker path to define open and closed positions of the door panel when the door panel is in the staging position.

A vehicle door assembly according to an exemplary aspect of the present disclosure includes, among other things, a first door, a second door and a first hinge assembly connected to the first door and the second door. The first door is movable between a first position and a second position about the first hinge assembly, and in the second position, the first door is received against the second door.

A vehicle includes a chassis, a cab coupled to the chassis, a cargo body coupled to the chassis and positioned rearward of the cab, a door coupled to the cab and selectively repositionable relative to the chassis between an open position and a closed position, and a door lock assembly configured to selectively prevent movement of the door from the closed position to the open position. The door lock assembly defines a key aperture configured to receive a key. The door lock assembly is coupled to the cab, and wherein the key aperture is positioned forward of the door.

A vehicle door system and a control method thereof, and a vehicle having the same. The vehicle door system comprises: a top door, the top door opening or closing a first opening of a vehicle body top portion; and a side door, the side door comprising a side door member and a side window, wherein the side door member opens or closes a second opening of a vehicle body side wall, the side window is mounted on the side door member, both a top edge and a side edge of the side window are configured to be frameless, and the side window is capable of raising or lowering relative to the side door member. When the side door body closes the second opening, the side window raises or lowers to open or close a third opening of the vehicle body side wall, wherein the third opening is located above the second opening, and the first opening, the second opening, and the third opening communicate with each other.
