A vehicle door opening and closing apparatus includes a vehicle door, a rail mounted on a vehicle body having a door aperture, a roller unit mounted on the vehicle door and configured to move along the rail and to allow the vehicle door to open and close in a sliding mode and in a swing mode, a sliding guide extending from a rear edge of the door aperture and extending straightly in a longitudinal direction of the vehicle body, a swing guide bent from the sliding guide toward an interior of the vehicle body, a center roller unit mounted on the vehicle door and guided along the sliding guide and the swing guide, and a variable stopper mechanism covering an exterior-side opening of the swing guide in the sliding mode and uncovering the exterior-side opening of the swing guide in the swing mode.

A voice activation system for a vehicle. The voice activation system for a vehicle which has at least one sound panel capable of providing vibrations of a user's voice from the outside of the vehicle into an inside area of the vehicle. A laser listening device is operably connected to the panel for receiving vibrations from a user's voice. A controller receives a pre-identified command of the user from the laser listener and operates an action in the vehicle in response thereto.

A vehicle door includes a belt structure and a rigid handle having a rigid base and a rigid outer grip portion. The rigid outer grip portion includes a portion that is spaced apart from the base to form a gap. The base of the handle is rigidly connected to the belt structure whereby the outer grip portion of the handle does not move relative to the belt structure. The vehicle door may include a powered door opening mechanism that moves a portion of the door away from a vehicle body when actuated.

A vehicle control device includes: an acquisition section configured to acquire a determination result for a first area indicating whether or not a predetermined communication terminal is in a predetermined first area outside a cabin of a vehicle, and to acquire a determination result for a second area indicating whether or not the communication terminal is in a second area that is further away from the vehicle than the first area; and a control section configured to perform a closing operation of a vehicle door based on the acquired determination result for the first area and on the acquired determination result for the second area.

An embodiment of the present disclosure provides a swing-in type of door structure of a vehicle that includes a door disposed in parallel at both sides of an entrance of a vehicle, and a door arm mounted on one side of the door to open or close the door by rotation, including: a center door bracket of which one end is fixed to one surface of an upper center of the door and that extends in a direction perpendicular to the door; a roller bracket of which one end is coupled to the other end of the center door bracket in a direction perpendicular to the center door bracket; and a roller mounted on the other end of the roller bracket and coupled to be rolled and rotated while in contact with a rail formed on a vehicle body of an upper side of the 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.

An assembly for a vehicle includes a front pillar and a rear pillar spaced along a vehicle-longitudinal axis. The front pillar and the rear pillar define a door opening. The assembly includes a first track supported by the front pillar and a second track supported by the rear pillar. The assembly includes a lower bar and an upper bar movable upwardly relative to the lower bar along the first track and the second track. The upper bar is movable between a lowered position and a raised position. The assembly includes a crossmember pivotally coupled to the lower bar and the upper bar.

Provided is a cab for a work machine capable of preventing an actuator from being damaged by vibration. A cab body is formed with a doorway. A door is rotatably supported on the cab body. The door opens and closes the doorway. A closed position locking unit locks the door so as to disable it from rotating relative to the cab body. The actuator generates a driving force to unlock the door locked by the closed position locking unit. The actuator is mounted on the cab body and is supported by the cab body.

A system includes: a door opening/closing switch which receives, from a user, a manipulation instruction for opening or closing the door; a door position sensor which detects a position of the door; a steering controller which measures a steering angle of the vehicle; a door controller which receives, from the door opening/closing switch, the manipulation signal for opening or closing the door, receives door position information from the door position sensor, receives steering angle information from the steering controller, and determines that the door and the wheel are in an interference state when the wheel is not in an aligned state in which the wheel is parallel to a longitudinal direction of the vehicle, when the user attempts to open the door; and a warning device which warns the user of a situation when the door controller determines that the door and the wheel are in the interference state.

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.
