DCFirst Claim
Patent Images
1. A double pivot door hinge for a door of a motor vehicle comprising:
- a door connector for connecting to a door of the motor vehicle;
a pillar connector for connecting to a door pillar or body of the motor vehicle;
a link;
a door-side pivot rotatably connecting the link and the door connector, the door-side pivot including a cam, a locking member and a biasing element biasing the locking member against the cam for imparting a door-side braking resistance between the link and the door connector; and
a pillar-side pivot rotatably connecting the link and the pillar connector, the pillar-side pivot imparting a pillar-side braking resistance between the link and the pillar connector;
wherein the pillar-side braking resistance is less than the door-side braking resistance during opening.

19. A method for providing a hinge to open a vehicle door comprising the steps of:
-
providing a first pivot to connect the vehicle door and a link so as to impart a door-side braking resistance between the vehicle door and the link, providing a second pivot to connect the link to a vehicle body so as to impart a body-side braking resistance between the vehicle body and the link, permitting the second pivot to rotate when the door opens from the closed position to an intermediate position, while keeping the first pivot rotationally stationary, and permitting the first pivot to rotate from the intermediate position to the fully open position while the second pivot remains rotationally stationary, wherein the body-side braking resistance is less than the door-side braking resistance during opening from the closed position, and the door-side braking resistance is less than the body-side braking resistance during closing from the fully open position.
