A sliding door system for a vehicle includes a sliding door including an upper edge and a lower edge; a lower roller coupled to the lower edge of the sliding door, the lower roller defining a groove; a lower guide coupled to the lower edge of the sliding door adjacent to the lower roller, the lower guide defining a groove; an upper roller coupled to the upper edge of the sliding door, the upper roller defining a groove; an upper guide coupled to the upper edge of the sliding door adjacent to the upper roller, the upper guide defining a groove; a lower rail affixed to a frame of the vehicle and disposed vertically below the lower edge of the sliding door, wherein the groove of the lower roller is engaged with the lower rail and wherein the groove of the lower guide partially surrounds the lower rail; and an upper rail affixed to a frame of the vehicle and disposed vertically above the upper edge of the sliding door, wherein the groove of the upper roller is engaged with the upper rail and wherein the groove of the upper guide partially surrounds the upper rail.

A guide rail includes: a first rail that has a bottom wall on which a load roller rolls and supports the weight of a sliding door; a second rail that has side walls on which two guide rollers roll and defines a moving direction of the sliding door; and a first restriction part that restricts the motion of the load roller in an axial direction.

A guide mechanism for a sliding door includes a rail configured to be mounted on the sliding door, a roller carriage configured to move along the rail, and including a roller bracket and a roller configured to be rotatably mounted on the roller bracket, a hinge arm configured to be pivotally connected to a vehicle body, a first shaft configured to pivotally connect the roller carriage to the hinge arm, and a second shaft configured to pivotally connect the hinge arm to the vehicle body.

A rolling device having a bearing housing accommodating a wheel axle carrying a wheel element, axle support members rotatably accommodated in the bearing housing and supporting the wheel axle, end portions of the wheel axle being connected to the axle support members in an eccentric position displaced from the rotational axis/4 line of the axle support members, a drive wheel connected to one of the axle support members for the axle support member to rotate following the rotation of the drive wheel, a first drive motor having a spindle engaged with the drive wheel to rotate the drive wheel and thereby the axle support member relative to the bearing housing, to displace the wheel element by eccentric movement between an extended position where at least a portion of the wheel element projects outside the bearing housing and a retracted position where the wheel element is located inside the bearing housing.

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 furniture hinge device capable of implementing wide range loading, comprising a housing and a fixing plate. A linkage assembly is provided between the housing and the fixing plate. A lever assembly and a power assembly are provided on the housing. The power assembly comprises a primary spring and a secondary spring. Positioning ends of the primary spring and the secondary spring are respectively mounted, from bottom to top, at a lower swinging end of the lever assembly. An adjustment assembly is provided on connection ends of the primary spring and the secondary spring. A fixing part of the adjustment assembly is fixedly mounted on a side plate of the housing. Adjustment parts of the adjustment assembly are respectively rotatably connected to the fixing part of the adjustment assembly and are connected to adjustment ends of the primary spring and the secondary spring.

The invention relates to a double-leaf vehicle door device comprising at least the following: two door leaves, each of which can be moved between an open position and a closed position in the form of a respective end position and into any intermediate position between the first open position and the first closed position, wherein a first movement of the first door leaf between the first open position and the first closed position is carried out without mechanically coupling the first door leaf to the second door leaf in contrast to a second movement of the second door leaf between the second open position and the second closed position, and a common locking device is provided which locks the first door leaf in the closed position when the first door leaf is located in the closed position and which locks the second door leaf in the closed position when the second door leaf is in the closed position. A pre-locking function is provided such that of the first door and the second door leaf, the door leaf which first reaches the closed position is held in the closed position at least until the other door leaf has also reached the closed position, and the locking device is additionally designed to only then lock or become capable of locking the first door leaf and the second door leaf.
