A structure for shielding a rail exposed to an outside of a sliding door vehicle includes a rail configured to be mounted in a vehicle, a drive unit movably connected to the rail, and a cover unit having one side connected to the drive unit and configured to be foldable and unfoldable. The cover unit is configured to move to open or close a space in which the rail is positioned.

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 provided with a first end portion rotatably connected to the door and a second end portion movable along a side sill of the vehicle body; a first slider pivotally coupled to the second end portion of the door arm so that the door arm rotates; a second slider coupled to the first slider to provide a path in which the first slider moves and to linearly move along the side sill; and a lower arm pinion gear which is rotatably coupled to the second end portion of the door arm and gear-engaged with the second slider to provide rotation force to the door arm so that the door arm rotates when the first slider moves in a longitudinal direction of the second slider.

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.

A control device for opening and closing bodies of vehicles comprises a driving device that drives an opening and closing body of a vehicle and a controlling unit that controls operation of the driving device. The controlling unit is configured so as to cause the opening and closing body to move while controlling the speed of the opening and closing body movement by executing speed feedback control and to set a plurality of control regions over the range of movement of the opening and closing body and change control properties for the speed feedback control in each of the control regions.

A vehicle door system includes, among other things, a vehicle body and a slidable door that is slidable back and forth relative to the vehicle body between an open position and a closed position. The system further includes an alignment bracket assembly having a door-mounted portion and a body-mounted portion. The door-mounted portion and the body-mounted portion are wedged against one another when the slidable door is in the closed position to restrict movement of the slidable door relative to the vehicle body when the slidable door is in the closed position.

An entrance handrail includes: a base portion provided proximal to an entrance opening of a vehicle so as to be turnable; a handrail body that extends from the base portion; and a rail portion that extends from the base portion and that holds a second end portion of a link arm such that the second end portion is slidable. A first end portion of the link arm is turnably attached to a slide door that is movable along an outer wall surface of the vehicle to open and close the entrance opening. The handrail body and the rail portion project outward of the vehicle when the slide door opens the entrance opening. The handrail body and the rail portion are disposed to extend along the slide door when the slide door closes the entrance opening.

A track extender for a sliding door track of an OEM passenger vehicle having a passenger opening, and a door operatively coupled to a sliding mechanism configured to slide along the sliding door track of the OEM vehicle. The sliding door track includes a track channel extending from the passenger opening toward a rear portion of the vehicle, wherein the sliding door track includes a first end located toward the passenger opening and a second end located toward the rear portion of the vehicle. The track extender includes a track extension body located at the second end of the track wherein the track extension body defines an extension channel. The extension channel is aligned with the track to lengthen the track and to extend a travel distance of the sliding mechanism along the track and to increase a width of the passenger opening.

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 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.

A system for opening and closing a sliding vehicle door includes a vehicle door that engages with the body in the closed position. A longitudinal track is fixedly mounted to an interior of the vehicle door. A hinged bracket is fixedly mounted to the vehicle body adjacent an opening defined by the vehicle body. The hinged bracket has a laterally compressed shape when the door is closed, and expands laterally outward when the door is opened. The door and the track fixed thereto slide longitudinally along the opened hinged bracket when the door is opened. The interface between the hinged bracket and the track remains at the same generally location relative to the vehicle body, and shifts relative to the vehicle door when the door is opened.
