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.

Systems and methods include providing an aircraft with a fuselage having a sliding door system disposed on at least one side of the fuselage. The sliding door system includes a forward sliding door having an upper slide rail and a lower slide rail, a rearward sliding door having an upper slide rail and a lower slide rail, an upper rail coupled to each of the upper slide rail of the forward sliding door and the upper slide rail of the rearward sliding door, a lower rail coupled to each of the lower slide rail of the forward sliding door and the lower slide rail of the rearward sliding door, and a plurality of actuators coupled to each of the upper rail and the lower rail and configured to displace and retract the forward sliding door and the rearward sliding door linearly with respect to the fuselage.

This disclosure relates to a motor vehicle with an arrangement configured to oppose movement of a vehicle door, and a corresponding method. An example motor vehicle includes a body, a door configured to slide relative to the body between an open position and a closed position, and a bracket connected to the door. The bracket includes a slot. Further, a locking arm is mounted to the body, and, when the door is in the closed position, the locking arm is configured to move such that the locking arm is received in the slot.

A sliding door device for a vehicle includes a door panel for opening and closing a door opening and covered by an upper trim and a lower trim, and a center rail mounted on the door panel to extend in a longitudinal direction of the vehicle body and providing a path for a center roller mounted on a center portion of the vehicle body, wherein a lower portion of the upper trim and an upper portion of the lower trim are disposed to overlap each other vertically. The center roller is mounted on a center roller mounting bracket including a first surface extending toward the vehicle body to be vertical to the door panel, a second surface bent from the first surface toward a lower side of the vehicle body, and a third surface extending from the second surface toward the vehicle body to be vertical to the door panel.

A sliding door device for a vehicle includes a door configured to open or close a door opening formed in a vehicle body, a door arm including one end portion rotatably connected to the door and the other end portion provided to be movable along a side sill of the vehicle body, a mover connected to the other end portion of the door arm and configured for straight line movement along the side sill of the vehicle body, a door arm plate configured to rotatably connect the mover with the other end portion of the door arm and provided to perform cycloid rotation and straight line movement when the mover moves along the side sill, a pin provided to protrude on the door arm plate, and a cycloid rail provided in the side sill and configured to provide a path on which the roller moves when the other end portion of the door arm moves along the side sill.

A slide door harness includes a wiring material, a vehicle body-side fixing portion provided in a vehicle body to rotatably hold an end of the wiring material below a lower end of an inner surface member of a slide door, and a door-side fixing portion provided on the slide door to rotatably hold another end of the wiring material, and the door-side fixing portion includes a holding portion configured to hold the another end of the wiring material toward the lower end side of the inner surface member, a first rotating shaft configured to allow the holding portion to rotate around a first rotation axis, and a second rotating shaft configured to allow the holding portion and the first rotating shaft to integrally rotate around a second rotation axis intersecting the first rotation axis.

An opening and closing structure of a sliding door for a vehicle includes: a sliding door disposed on a side surface of the vehicle and configured to be slidably open and closed in a longitudinal direction of the vehicle; at least one rail arranged in a longitudinal direction of the vehicle on one of a vehicle body of the vehicle and the sliding door; at least one roller arranged on the other one of the vehicle body and the sliding door, the at least one roller configured to slide while being fitted in the at least one rail; and a sliding unit disposed on a side of the vehicle body or the sliding door on which the at least one roller is arranged, the sliding unit configured to slide the at least one roller in a direction in which the sliding door slides. The at least one roller is configured to slide with respect to the vehicle body and the sliding door.

A structure includes a lower rail mounted to a lower portion of a vehicle body in a longitudinal direction of the vehicle body. A lower-rail roller part is rollably connected to the lower rail. A lower-rail swing arm is rotatably connected to the lower-rail roller part and a door. A lower guide rail is mounted to the door and defines a lower guide path in the longitudinal direction of the vehicle body. A lifter has a first end that moves along the lower guide path, and a second end that is fixed to the vehicle body. The lifter applies a force in a direction from the door toward the vehicle body. An upper guide rail is mounted to an upper portion of the vehicle body. An upper-guide roller part is mounted to the door to be seated in the upper guide rail.

A door track assembly along which a vehicle door travels between an open position and a closed position is provided. The door track assembly includes a first track portion defining a first track surface, a second track portion, and a third track portion coupled to the second track portion. The third track portion includes a top wall, a first side wall, a second side wall, and a lower wall, where the lower wall defines a second track surface. The first track portion defines at least a first finger and a first groove in the first track surface, and the third track portion defines at least a second finger and a second groove in the second track surface. The first finger is disposable within the second groove and the second finger is disposable within the first groove such that the first track surface and second track surface are substantially coplanar.

An embodiment is a vehicle door opening and closing apparatus. The vehicle door opening and closing apparatus including a vehicle door, a rail mounted on a vehicle body, a roller unit mounted on the vehicle door, the roller unit configured to move along the rail and allow the vehicle door to open and close in a mode selected from a swing mode and a sliding mode, and a hold lock mounted on the vehicle body, the hold lock including a passing rod configured to releasably hold the roller unit in a predetermined position.
