A door system has a door leaf configured to be moved between closed and opened positions while carrying out a door leaf movement. The door leaf is moved in the vehicle transverse direction across a door leaf movement distance in the vehicle transverse direction, a door seal, disposed underneath a lower edge of the door leaf closing off the door leaf towards the bottom, and extends along the lower edge. The door seal is arranged such that the door seal, when the door leaf movement is carried out, undergoes a door seal movement and is moved in the process in the vehicle transverse direction across a door seal movement distance in the vehicle transverse direction. An arrangement of the door leaf and door seal that ensures that the door seal movement distance in the vehicle transverse direction is smaller than the door leaf movement distance in the vehicle transverse direction.

A vehicle door device includes a first link arm and a second link arm each having a first pivot coupling point with respect to a vehicle body and a second pivot coupling point with respect to a door of a vehicle, and a biasing force applying device configured to, during opening and closing operation of the door based on an operation of a link mechanism formed by the first link arm and the second link arm, apply, to the door, a biasing force in a direction in which a rotational moment around the second pivot coupling point generated based on inertia of the door generated in the door accompanied by the operation of the link mechanism is reduced.

A door linkage system for guiding a door of a motor vehicle between an open position and a closed position relative to a vehicle body includes at least one linkage pivotally connected between the door and the vehicle body to move a rear portion of the door away from the vehicle body substantially in a cross vehicle direction to a partially open position while a front portion of the door concurrently moves substantially in a longitudinal vehicle direction of the vehicle, and then, move the front portion and the rear portion of the door concurrently in substantially the longitudinal vehicle direction of the vehicle to the open position.

The motorized drive according to the application is particularly suitable for auxiliary or emergency drives and is configured to open or close a wing of a barrier such as a door. The motorized drive includes a motor and a reduction unit through which the motor can open or close the wing, an auxiliary motor including a helical spring which is able to absorb mechanical energy during the opening of the wing and release it during the closing of the same, a reduction unit connecting the auxiliary motor to the wing. A first and a second toothed profile realize a gear with a variable transmission ratio. The first and/or the second toothed profile form at least one toothing having a pitch profile which is substantially non-circular or not formed by a simple arc of a circle or a straight line.

A sliding door for a vehicle, which is applicable to a door portion to which a straight rail is difficult to be applied, may include a door rail mounted in a door which is configured to be closed to a vehicle body in a vertical direction of the vehicle; a vehicle body rail mounted in the vehicle body to which the door is configured to be closed in a longitudinal direction of the vehicle; and a moving arm having one end portion which is movably coupled along the door rail in the vertical direction to open or close the door in a transverse direction of the vehicle body during moving, and the other end portion which is movably coupled along the vehicle body rail in a longitudinal direction to allow the door to be slidingly moved in a longitudinal direction of the vehicle body during moving.

Loading, shifting, and staging objects in automated or semi-automated fashion including systems, methods, and apparatuses for the same. The embodiments hereof enable automated and/or semi-automated loading, shifting, organizing, staging, and accessing of objects in different environments, e.g., those associated with a logistics network operation. For example, one such environment is a vehicle. In one aspect, a loading mechanism is used to load objects into a storage space of the vehicle. In another aspect, a shifting mechanism is used to shift objects in a storage space of the vehicle. In another aspect, a door assembly allows for automated opening and closing of a door into a storage space of a vehicle. In addition, methods of manufacturing and using the same are provided.

A door opening assembly is provided for moving a door of a vehicle between an open position and a closed position. The assembly includes a frame member coupled to the vehicle, a link is coupled to the frame member, and a link arm pivotally coupled to the link. A pivot arm is pivotally coupled to the frame member and a pivot bracket is pivotally coupled to the door and the pivot arm. The pivot bracket includes a slot such that a pin on the link arm slides therethrough. The assembly includes a gear rack and a gear operably coupled to the gear rack. The gear is driven by a motor as the door moves between its open and closed positions. The assembly further includes a guide track coupled to the vehicle and a roller rotatably driven along the guide track as the door moves between its open and closed positions.

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.
