An assistance apparatus for opening and closing a scissor door for a vehicle includes: a door hinge having one side installed at a vehicle body to be rotated vertically through a hinge shaft, and having a door mounted at an opposite side thereof; a gas lifter having a first side installed at the vehicle body, and having a second side installed at the door hinge to assist a rotational force of the door hinge or keep a posture thereof through compression and elongation; and an opening and closing assistance unit for providing the rotational force to the door hinge in interlocking with the pressing operation of a vehicle passenger.

A multi-axis hinge mechanism for a vehicle door. The multi-axis hinge mechanism moves the vehicle door laterally and vertically by means of multiple axial rotations. An actuator pivots the door hinges attaching the door to the vehicle to move the door away from the vehicle while a set of gears translates the motion of the actuator into a vertical rotation of the door.

A bi-directional door opening structure includes a front door configured to be rotatably opened with respect to a front hinge part positioned in a roof of a vehicle, a rear door configured to be rotatably opened with respect to a rear hinge part positioned in the roof of the vehicle, and a drive unit positioned in the roof at a point where the front door and the rear door are adjacent to each other, and configured to apply an opening force to the front door and the rear door, wherein the drive unit includes a spindle unit configured to open at least one of the front door and the rear door, which has been unlocked by a driving force applied from a driving part, and a differential gear configured to deliver the driving force between the spindle unit and the driving part.

A door hinge mount of a side external panel for a vehicle, may provide the door hinge mount, capable of being formed of a material, requiring low initial investment expenses, and securing the same level of rigidity as in the case where a steel material is used.

An emergency exit door assembly for a vehicle. The door assembly comprises a main panel including an interior-facing surface and exterior-facing surface. The main panel is rotatably connected to the vehicle, such that the main panel is configured to selectively alternate between a closed position in which the interior-facing surface faces an interior of the vehicle and an open position in which the interior-facing surface faces an exterior of the vehicle. The door assembly additionally comprises one or more projection members extending from the interior-facing surface of the main panel. The projection members each include a first major surface configured to support articles within an interior of the vehicle while the main panel is in the closed position. The door assembly further comprises a support mechanism configured to support the main panel in the open position.

A door hinge is provided to slant such that a free end of a door is rotated obliquely upward while the door is opened, and an energizing type balancer to assist an opening/closing operation of the door is provided. A hinge axis of the door hinge slants relative to a vertical line, having an upper side thereof being positioned on an inward side in a vehicle width direction and on a forward side in a vehicle longitudinal direction such that a locus of the free end of the door while the door is opened becomes substantially horizontal or lowers in an opening direction at a point before the door is opened to a maximum open position.

A mechanism for mounting of a hinged car door, comprising a stabilizing frame (1) attached to a vehicle frame (15). The stabilizing frame (1) is equipped, in its lower part, with a lock (6) for stabilizing a bracket (3) of a door (14) and, in its upper part, the stabilizing frame (1) is equipped with a toothed pinion (5) and at least one guiding roller (4), whereas a toothed arm (2) is arranged between the toothed pinion (5) and the guiding roller (4), and the bracket (3) of the door (14) is swing attached to the toothed arm (2), whereas the door (14) is attached to the bracket (3) of the door (14) by means of pins (13) of the door (14).

An exemplary motor vehicle includes a first door on a first side of the motor vehicle including a first pad adjacent a rear edge of the first door, and a second door on the first side of the motor vehicle including a second pad adjacent a front edge of the second door. Further, the first pad and second pad are arranged such that, in a first condition, the first pad and second pad are spaced-apart from one another and, in a second condition, the first pad and second pad contact one another to prevent overlap of the first door and second door.

A vehicle door arrangement includes a first closing element arranged on a vehicle door and a second closing element arranged on a bodywork of the vehicle. The first and closing elements can be connected to each other in a positive looking manner to hold the door on the bodywork. A door handle is connected to a sensor for detecting a pressure input or a pulling input of a user on the door handle. The sensor is connected to a control unit, which controls a locking actuator and a door opening actuator. The locking actuator separates the first and second closing elements, and the door opening actuator opens the vehicle door relative to the bodywork. The control unit controls the locking actuator to separate the first closing element and the second closing element in response to a detected pressure input or pulling input, and to control the door opening actuator to open the door relative to the bodywork.

A ramp door closure apparatus is provided for recreational vehicles, having a recessed linear actuator both draw a cable from a mounting bracket on the ramp door adjacent to the RV opening, to raise and lower the ramp door, and then cam a locking pin fixed to the ramp door into a seal tight position after the ramp door is raised. Upon release of the locking pin from the cam when opening the door, an initial push is provided to facilitate downward rotation of the ramp door. The linear actuator is selectively detachable from the cable so as to allow manual raising and lowering of the ramp door from within the RV, by means of releasable pins accessed in the mounting structure.
