The hinge device performs the opening and closing of a door of a vehicle without the door changing orientation. The device has an L-shaped arm provided with two ends attached in a pivotable way, around parallel rotation axes, to respective mounting bodies, one being fixable to the door and the other to the frame of the vehicle. Each body has a concentric pulley body with the respective rotation axis and fixed to a respective mounting body. The device further has a linking mechanism that extends along the arm and has a path formed by a first segment and a second segment that cross at least once.

A door drive assembly including: a drive arm including a first end configured to be rotatably coupled to the body and a second end configured to be rotatably coupled to the door. The door drive assembly also includes a drive mechanism coupled to the drive arm and configured to rotate the drive arm between an open position and a closed position. The door drive assembly also includes a control arm including a first end configured to be rotatably coupled to a vehicle body and a second end configured to be rotatably coupled to the door. The door drive assembly also includes a race configured to be disposed between the body and the first end of the control arm where the first end of control arm is configured to translate by a first distance along the race as the drive arm rotates between the open and closed positions.

A door closure assembly and a method of moving a door is disclosed. The door closure assembly includes a cabinet attachment member attachable to a cabinet, a door attachment member attachable to a door, and first and second arms hingedly attached to the cabinet attachment member and the door attachment member. In some embodiments, the cabinet attachment member is attached to a central portion of the door and the door attachment member is attached to an end portion of the door.

A vehicle door system includes doors with a door module attached to a hinge module, which is attached to the vehicle body. The door module includes a latch mechanism configured to engage a striker pin of the vehicle body, with a pawl that pivots to accommodate a misalignment with the striker pin during a door closing operation, with the latch mechanism shifting following engagement with the striker pin. A door check mechanism includes a permanent magnet and a steel plate. Activation of the permanent magnet shifts the steel plate from a closed position to an open position permitting the hinge module to move from a locked position. An interface between doors includes a primary and secondary seal each having a constant cross section, with filler pieces disposed between the door and the secondary seal along a portion of the interface.
