A vehicle opening and closing apparatus that opens and closes an opening and closing body provided on a vehicle includes: an electric motor that drives the opening and closing body; a position detection part that detects a position of the opening and closing body; a measurement part that measures a current value which flows in the electric motor when the opening and closing body arrives at a predetermined position; a counter that counts up a count value based on the current value; and a determination part that stops, for a predetermined period of time, the next and subsequent opening and closing operation of the opening and closing body when the count value exceeds a first threshold value.

A door roller includes a carriage member comprising a plurality of bores, and a plurality of roller assemblies connected to the carriage member, each roller assembly of the plurality of roller assemblies including a pivot bearing rotatably disposed within a bore of the plurality of bores and a pair of rollers coupled to the pivot bearing. Each wheel assembly is configured to pivot relative to the carriage member.

A hold lock mechanism for a vehicle door, the hold lock mechanism including a grip assembly configured to be mounted on a vehicle body, the grip assembly including a pair of grip members configured to releasably grip a door component and a hook provided on at least one of grip members, and a release assembly mounted on the door component, the release assembly including a release member configured to releasably engage with the hook.

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 motor vehicle having at least one side door opening formed in the body of the same and having a sliding door closing the same, wherein the side door opening has a sill structure for supporting and movably guiding the sliding door, wherein the sill structure has a hollow profile oriented in the vehicle longitudinal direction (x-direction) and formed as a welded part, and wherein the hollow profile on the vehicle exterior has a welding flange, extending along the sill structure and oriented in the vehicle vertical direction (z-direction), as a mounting flange for a door seal, which delimits an indentation formed in an upper section of the outer contour of the hollow profile. It is provided advantageously that a recess having at least one guide rail for a roller guide of the sliding door is disposed above the indentation, which recess is detachably secured to the sill structure.

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 structure includes a lower rail mounted to a lower portion of a vehicle body in a longitudinal direction thereof. 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 the 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 comes into contact with the lower guide path, and a second end that is fixed to the vehicle body, and applies a force in a direction of pushing the lower guide rail. 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 sliding-door drive device includes: a motor; a speed reducing mechanism reducing rotation of the motor; opening and closing cables having respective one ends secured to a sliding door of a vehicle; an opening drum, having the opening cable wound therearound, to be rotated by the motor through the speed reducing mechanism; and a closing drum, having the closing cable wound therearound, to be rotated by the motor through the speed reducing mechanism. Further, rotation axes of the motor, the opening drum, and the closing drum are parallel, and the opening drum and the closing drum are arranged parallel in radial directions thereof.

A front link of a sunroof apparatus shifts, based on power transmitted from a first guide shaft of a front shoe, among a full-close corresponding position that allows a movable panel to be arranged in a full-close position, a front-up corresponding position that allows the movable panel to be arranged in a front-up position and a full-open corresponding position that allows the movable panel to be arranged in a full-open position. In a side view from a width direction of the front link, a first guide groove, through which the first guide shaft is inserted, extends so as to intersect with a line segment connecting a front connection shaft and a front support shaft.
