Abstract

A door assembly includes a door that turns between a fully-closed position and a fully-open position to open or close a door opening, and hinges that support a front edge portion of the door and are provided such that the trajectory of the center of gravity of the door when the door turns from the fully-closed position to the fully-open position is curved upwardly in an up-down direction and the highest point of the trajectory is positioned between both ends of the trajectory.

Claims (16)

1. A vehicle door assembly comprising:

a door that turns between a fully-closed position and a fully-open position to open or close a door opening; and

a hinge that supports a front or rear edge portion of the door and is provided such that a trajectory of a center of gravity of the door when the door turns from the fully-closed position to the fully-open position is curved upwardly in a vehicle up-down direction and a highest point of the trajectory is positioned between both ends of the trajectory, wherein

the highest point of the trajectory is positioned closer to the fully-closed position with respect to a center of the trajectory.

2. The vehicle door assembly of claim 1 , wherein

a turning axis of the hinge upon turning of the door is inclined in a vehicle width direction, and displaces inwardly in the vehicle width direction as the turning axis extends upwardly.

3. The vehicle door assembly of claim 1 , wherein

a turning axis of the hinge upon turning of the door is inclined in a vehicle front-rear direction, and a distance between the turning axis and the center of gravity of the door in the front-rear direction increases as the turning axis extends upwardly.

4. A vehicle comprising:

a pair of front wheels and a pair of rear wheels;

a vehicle body having a pillar forming part of an edge portion of a door opening; and

a door assembly provided at the door opening,

wherein the door assembly includes

a door that turns between a fully-closed position and a fully-open position to open or close the door opening, and

a hinge that supports a front or rear edge portion of the door and is provided such that a trajectory of a center of gravity of the door when the door turns from the fully-closed position to the fully-open position is curved upwardly in a vehicle up-down direction and a highest point of the trajectory is positioned between both ends of the trajectory, wherein

the highest point of the trajectory is positioned closer to the fully-closed position with respect to a center of the trajectory.
