A vehicle door check mechanism includes a strap body mounted on a portion of a vehicle door adjacent to a rotation axis of the vehicle door, and configured to move with the vehicle door as the vehicle door swings around the rotation axis, and a hold unit configured to allow the strap body to be held at regular intervals, wherein the strap body is curved to have a predetermined curvature radius. A center of the curvature radius is located on the rotation axis of the vehicle door, and the strap body has a fixed end which is fixed to the vehicle door, and a free end which is spaced apart from the vehicle door.

A vehicle door opening and closing apparatus includes a rail mounted on a vehicle body, a roller unit mounted on a vehicle door, the vehicle door having a main latch releasably engaged with a main striker mounted on the vehicle body, the roller unit configured to allow the vehicle door to open and close in a sliding mode and a swing mode, and an outside handle operatively connected to the main latch, and including a handle base mounted on the vehicle door and a handle grip movably mounted on the handle base, wherein the handle grip is slidable in a longitudinal direction of a vehicle, and pivotal in a transverse direction of the vehicle, and wherein as the handle grip slides, the sliding mode is selected, and as the handle grip pivots, the swing mode is selected.

A spindle type structure includes a lower rail mounted in a longitudinal direction at a lower side of a vehicle body, a lower rail roller unit rollably connected to the lower rail, a lower rail swing arm rotatably connected to the lower rail roller unit and a door, a lower guide rail mounted on the door and configured to form a lower guide route in the longitudinal direction, and a spindle assembly positioned at one side of the lower rail, the spindle assembly including a spindle connected in the longitudinal direction to a fixing unit fixed to the vehicle body, having one end rollably connected to the lower guide rail, having a threaded portion formed on an outer circumferential surface thereof, and being configured to be movable in a threaded manner between the vehicle body and the door.

A vehicle includes a vehicle body having a door frame defining a door aperture, a vehicle door, a rail mounted on the vehicle body, a roller unit mounted on the vehicle door and configured to move along the rail and allow the vehicle door to open and close in a sliding mode and a swing mode, a center rail extending from an edge of the door aperture, and a center roller unit including rollers configured to be guided along the center rail, a roller bracket having the rollers mounted thereon, a roller-side hinge element connected to the roller bracket, and a door-side hinge element rotatably connected to the roller-side hinge element, wherein the roller-side hinge element and the door-side hinge element are releasably connected.

The disclosure relates to a sliding fenestration system assembly, such as a door or window system. The sliding fenestration system includes a sill having a first track channel and a second track channel formed thereon. A sill track including a first track segment, a second track segment, and a third track segment is coupled to the sill such that the first track segment is positioned within the first track channel, the third track segment is positioned within the second track channel, and the second track segment extends between the first and second track channels. The system further includes a sliding panel having one or more bottom guide assemblies, the assemblies engaging the sill track and operable to accommodate movement of the sliding panel along the sill track to reduce friction at a sealing interface between the sliding panel and the fenestration frame assembly.

A dual lower rail structure for opposite sliding doors is provided. The dual lower rail structure includes a first lower rail mounted in a longitudinal direction at a lower side of a vehicle body, a second lower rail mounted in a longitudinal direction on a vehicle body at one side of the first lower rail, a first lower rail roller unit rollably connected to the first lower rail, a second lower rail roller unit having one end rollably connected to the second lower rail, and the other end connected to a sliding door, and a lower rail swing arm rotatably connected to the first lower rail roller unit and the sliding door.

A sliding/swing complex door for a vehicle includes a sliding door configured to be opened upon a first operation of an outside handle positioned on an outside of the sliding door, a swing door configured to be integrated and opened with the sliding door upon a second operation of the outside handle, and a fixing unit configured to be opened in such a way to be integrated and rotated with the swing door in a state in which the sliding door is fully opened.

A sliding door mechanism includes a track that is fixed in position relative to a door opening, a post fixed in position relative to the track, and a member that is moveable longitudinally with respect to the track, the member being configured to be guided by the track. The mechanism further includes an arm mounted to the member, the arm rotatable about a vertical axis and configured to be pivotably attached to the sliding door. The arm defines a slot that is configured to receive the post as the door is moved from an open position toward a closed position such that the post urges the arm to rotate relative to the carriage such that the arm transmits a force to the door to urge the door to move laterally into the door opening.

A link mechanism for a vehicle door is provided. The link mechanism includes a body having a first end portion facing a vehicle body and a second end portion facing a vehicle door and a first mounting member that is mounted on the vehicle body, and rotatably connected to the first end portion of the body through a first shaft. A second mounting member is mounted on the vehicle door, and is rotatably connected to the second end portion of the body through a second shaft. A rotation restricting unit selectively restricts a rotation of the second mounting member.
