A sliding door device for a vehicle includes a door arm including a first end portion rotatably connected to an end portion of the door and a second end portion movable along a side sill of the vehicle body, a door power connection portion provided in the door arm, and a vehicle power connection portion provided in a position corresponding to the door power connection portion of the vehicle body and electrically connected to the door power connection portion according to rotation of the door arm, wherein the vehicle power connection portion includes: a first vehicle power connection portion electrically connected to the door power connection portion when the door is closed, and a second vehicle power connection portion electrically connected to the door power connection portion when the door is opened.

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 roller unit includes a base bracket (2) that supports a slide door, a cable holder (11) formed integrally with the base bracket (2) and that holds cable ends (112a and 113a) of cables (112 and 113), and a cable guide (40) detachably installed at the cable holder (11) and that guides the cables (112 and 113), wherein the cable guide (40) is formed to separate the cables (112 and 113) from the base bracket (2), and a load applied to the cable guide (40) by tensile forces of the cables (112 and 113) is received by the cable holder (11) and the base bracket (2).

An articulating mechanism for opening and closing a vehicle door utilizes a first mechanism having a first motion profile and a second mechanism having a second motion profile. To open the door, the first mechanism begins the first motion profile before the second mechanism begins the second motion profile. To close the door, the second mechanism completes the second motion profile before the first mechanism completes the first motion profile.

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 sliding door system for a vehicle includes a door frame defining a door opening and a sliding door covering at least a portion of the door opening in a closed position. An upper door slide assembly and a lower door slide assembly collectively interconnect the sliding door to the door frame and each are configured to slide the sliding door relative to the door frame from the closed position to an open position to dispose the sliding door either forward or rearward of the door opening. The lower door slide assembly includes a lower track extending along the sliding door and a lower hinge assembly pivotably connected to the door frame and slideably mated with the lower track for effectuating pivoting and sliding movement of the sliding door between the open and closed positions.

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.

A door assembly includes a door, a door actuator mechanism configured to transition the door between an open position and a closed position, a first latch configured to hold the door in the closed position, and a second latch engaging with a portion of the door actuator mechanism and being configured to hold the door in the closed position. The second latch includes a cam and a biasing member coupled to the cam. The biasing member is configured to transition the cam between a first position in which the cam engages the portion of the door actuator mechanism, and a second position in which the cam disengages the portion of the door actuator mechanism.

A cross-sectional shape of an open-side cable 22a is formed into a round shape, and a cross-sectional shape of respective connecting units 52 between a pulley groove 50 of a pulley 46 and flange portions 51 is formed into a circular arc shape. Thus, it is possible to surely suppress damage of the open-side cable 22a caused by being strongly pressed to a corner as a conventional manner. Therefore, it is possible to improve durability of the open-side cable 22a, whereby it is possible to extend a maintenance cycle of a driving unit and obtain high reliability thereof.

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.
