In a door hinge device for vehicles, in a vehicle without a B pillar, a hinge slider connected to a hinge portion of a door slidably moves in an external diagonal direction of a vehicle body along a rail in a case to secure a rotational trajectory of the door, and then a first striker configured in the hinge slider is restrained to a hinge latch unit fixed onto the rail inside the case in association with an action of a second striker provided at one side of the door to fix a slide movement location of the hinge slider, stably achieving an opening/closing operation of the door.

An eccentric hinge includes a rail, a stop block arranged on a first end of the rail, a fixing rod parallel with the rail, a sliding block, a connecting rod and a transmission rod, where the sliding block is arranged on the rail; a first end of the connecting rod is connected with a second end of the rail; a second end of the connecting rod is connected with the fixing rod; a first end of the transmission rod is connected with the sliding bock; a second end of the transmission rod is connected with the connecting rod; when the eccentric hinge is in a closed state, a first centerline of the fixing rod and a second centerline of the rail are parallel lines in a same plane; and a distance between the parallel lines is greater than 0 mm and less than or equal to 10 mm.

A sliding door assembly includes a door panel, a frame that supports the door panel and includes a bottom member with a lower profile and a top member with an upper profile, wherein the lower profile and the upper profile are parallel to one another. A lower sliding assembly is operatively coupled to a bottom of the door panel and engages the lower profile, and an upper sliding assembly is operatively coupled to a top of the door panel and engages the upper profile. A gasket interposes the door panel and a portion of the frame when the door panel is in a sealed position. The door panel is movable between the sealed position, where the gasket creates a sealed interface between the door panel and the frame, and a sliding position, where the door panel is moved laterally relative to the frame while remaining substantially perpendicular to a floor.

A vehicular door assembly that can be opened by both sliding and pivoting movements includes an outer frame portion and an inner door portion. One of the outer frame portion and the inner door portion is slidably mounted on the vehicle, and the other of the outer frame portion and the inner door portion is pivotally mounted on the vehicle. In a first embodiment, the outer frame portion is slidably mounted on the vehicle, and wherein the inner door portion is pivotally mounted on the outer frame portion. In a second embodiment, the outer frame portion is pivotally mounted on the vehicle, and wherein the inner door portion is slidably mounted on the outer frame portion.

A coach door of a vehicle is provided. The door includes a hinge assembly that has a first hinge hinged to a vehicle body and a second hinge hinged to the first hinge and engaged with a rear end of a rear door. An opening start device rotates the rear end of the rear door to the outside of the vehicle at an early stage of opening of the rear door and a closing end device rotates the rear end of the rear door to the inside of the vehicle at a last stage of closing of the rear door. A guide unit is configured to guide a front end of the rear door to move the front end of the rear door in a longitudinal direction of the vehicle at the initial stage of opening of the rear door and the last stage of closing of the rear door.

In a second embodiment, the outer frame portion is pivotally mounted on the vehicle, and wherein the inner door portion is slidably mounted on the outer frame portion.

According to some embodiments, a door system includes a door attachment device and a receiver. The door attachment device may be coupled to a door, and the receiver may be coupled to a door frame. A receiving surface of the receiver may be configured to at least partially receive the door attachment device along a first axis. The receiving surface may have a non-planar portion curved relative to the first axis such that the receiving surface responds to movement of the door attachment device in a direction parallel to a second axis, the second axis perpendicular to the first axis, by repositioning the door attachment device in a third direction perpendicular to the plane formed by the first axis and the second axis.
