A sliding door device for a vehicle, includes: a door that opens or closes a door opening formed in a vehicle body; a door arm having a first end portion connected to the inside of the door and to extend toward a side sill of the vehicle body; a mover disposed to face the door and to be movable along the side sill; a body arm having a first end portion connected to one side of the mover, wherein the body arm is disposed in parallel to the door arm to extend toward the inside of the door; and a roller having an edge portion, respectively coupled to the door arm and the body arm so that the door arm and the body arm relatively move to each other in accordance with rotation of the roller.

A vehicle has a sliding door fitted with a rotatable brake member to apply a braking force to the sliding door when the vehicle is on a slope. The brake member is automatically rotated about a pivot axis X-X by a moveable member forming part of an actuator when the vehicle is resting on a slope into a position in which a braking force is applied to the sliding door by the interaction of the brake member with an elongate track in the form of a sliding door support track.

A sliding door device for a vehicle may include a sliding door opening/closing a door opening formed in a vehicle body, a door rail mounted on the sliding door, a vehicle body rail mounted on the vehicle body, a central support structure for movably supporting the sliding door, a hook releasably locking the central support structure to the door rail, and a lower support structure for movably supporting a lower portion of the sliding door. The central support structure includes a central slider. The lower support structure includes a lower slider, a gear device, a link mechanism, a chain, and a chain tensioner.

An apparatus for window is used for moving a movable window plate among an insertion position for being inserted into an aperture portion of a fixed window plate, an extraction position for being extracted from the aperture portion toward an indoor side, and an opening position for being moved from the extraction position in a sliding direction that is different from an inserting and extracting direction to open the aperture portion. The apparatus includes a rotating shaft rotatably supported at a predetermined position for the movable window plate; a movement conversion mechanism configured to convert a rotation of the rotating shaft into a translation of the movable window plate between the insertion position and the extraction position; and a drive shaft, fixed to the rotating shaft, configured to rotate the rotating shaft around a central axis of the rotating shaft by revolving around the central axis of the rotating shaft.

The present disclosure relates to a windows and doors assembly having a ventilation function and a horizontal contact function, and more particularly to a horizontal contact windows and doors assembly for crime prevention and security functions by preventing a window from being open even when the window is slightly open and it is possible to ventilate with the outside air. To achieve the objective of the present disclosure, the windows and doors assembly having a ventilation function and a horizontal contact function includes a window frame, and a windowsill in which the window frame is slidably installed, a handle rotatably installed on the window frame, an engagement unit provided on a lateral surface of the window frame, linked to movement of the handle, and moved in upward and downward directions, an engagement guide provided on the windowsill to face the engagement unit and configured to catch or not catch the engagement unit depending on a position of the engagement unit, and a horizontal moving device provided on at least one of a top surface or a bottom surface of the window frame, linked to the handle, and configured to make the window frame horizontally come into contact with the windowsill or to release horizontal contact depending on movement of the handle, and in this case, when a contact state of the window with respect to the windowsill by the horizontal contact device is released while a catching operation between the engagement unit and the engagement guide is performed, it is possible to ventilate through a gap between the window and the windowsill, the window is restrictly moved to form the gap, and the window is prevented from being freely open.

A structure can provide separation strength of an opposed sliding door. The structure includes a rail configured to be mounted to a vehicle body in a longitudinal direction thereof, a first bracket configured to be fixedly connected to the vehicle body at a first side of the rail and having a hook receiver, a slider inserted into the rail and coupled thereto, a swing arm configured rotatably connected to a sliding door and to the slider, and a second bracket fixedly connected to the swing arm. The second bracket has on a first side thereof a hook to be received in the hook receiver. The hook is received in the hook receiver when a load is applied to the sliding door in a direction from an inside to an outside of the vehicle body with the sliding door being closed.

A vehicle includes a chassis, a door track, a door operatively connected to the door track and adapted to move between a closed position and an open position, and a hinge assembly coupled to the door. The hinge assembly is movably coupled to the door track and includes a first bracket coupled to the door, a second bracket coupled to the first bracket, and a transport assembly coupled to the second bracket and adapted to move along the door track as the door moves between the open and closed positions. The transport assembly includes a coupling member for releasably coupling the second bracket to the transport assembly. Upon movement of the second bracket from the first position to the second position, the door moves to an extended open position with respect to the door track.

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.
