Double-pivot hinge for motor vehicle door
First Claim
1. A double pivot door hinge for a door of a motor vehicle comprising:
- a first hinge assembly, the first hinge assembly including a first door connector for connecting to the door of the motor vehicle, a first pillar connector for connecting to a door pillar or body of the motor vehicle, and a first link rotatably connected to the first door connector at a first door-side pivot and rotatably connected to the first pillar connector at a first pillar-side pivot;
a second hinge assembly, the second hinge assembly including a second door connector for connecting to the door and a second pillar connector for connecting to the door pillar or the body, and a second link rotatably connected to the second door connector at a second door-side pivot and rotatably connected to the second pillar connector at a second pillar-side pivot; and
a connecting member rigidly joining the first and second hinge assemblies;
wherein the first and second links are u-shaped.

Abstract
A double pivot notch-brake hinge for securing a door to a motor vehicle body, including a first leaf or connector securable to a door pillar of the vehicle body, a second leaf or connector securable to the door, and a U-shaped link pivotally connecting the first and the second leaves. The U-shaped link has two opposite legs at its respective ends, and gudgeons for receiving hinge pins and defining, respectively, pillar-side and door-side pivot connections of the U-shaped link with the first and the second connectors. The pillar and door side pivots are checked with a resistance pivot using a notch-brake mechanism, which allows controlled movement of the pivot.

9. A double pivot door hinge for a door of a motor vehicle comprising:
-
a first hinge assembly, the first hinge assembly including a first door connector for connecting to the door of the motor vehicle, a first pillar connector for connecting to a door pillar or body of the motor vehicle, and a first link rotatably connected to the first door connector at a first door-side pivot and rotatably connected to the first pillar connector at a first pillar-side pivot; a second hinge assembly, the second hinge assembly including a second door connector for connecting to the door and a second pillar connector for connecting to the door pillar or the body, and a second link rotatably connected to the second door connector at a second door-side pivot and rotatably connected to the second pillar connector at a second pillar-side pivot; and a connecting member rigidly joining the first and second hinge assemblies; wherein a rotation of the first link at the first door-side pivot is resisted by a first braking resistance between the first link and the first door connector and a rotation of the first link at the first pillar-side pivot is resisted by a second braking resistance between the first link and the first pillar connector, the second braking resistance being less than the first braking resistance during opening. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method of opening a vehicle door connected to a vehicle pillar by a double pivot door hinge comprising a door-side pivot connected to the door, a pillar-side pivot connected to the pillar, and a link connecting the door-side pivot and pillar-side pivot, the method comprising the steps of:
-
opening the door from a closed position to an intermediate position while overcoming a pillar-side resistance between the pillar-side pivot and the link while simultaneously failing to overcome a door-side resistance between the door-side pivot and the link, thereby causing the link to rotate about the the pillar-side pivot while the link remains rotationally stationary about the door-side pivot; opening the door from the intermediate position to a fully-open position while overcoming the door-side resistance, thereby causing the link to rotate about the the door-side pivot.

23. A method of opening a vehicle door connected to a vehicle pillar by a double pivot door hinge comprising a first door-side pivot connected to the door, a first pillar-side pivot connected to the pillar, and a first link connecting the first door-side pivot and first pillar-side pivot, and a second door-side pivot connected to the door, a second pillar-side pivot connected to the pillar, and a second link connecting the second door-side pivot and second pillar-side pivot, and a connecting member rigidly connecting the first link and second link, the method comprising the steps of:
-
opening the door from a closed position to an intermediate position while overcoming a pillar-side resistance between the first pillar-side pivot and the first link while simultaneously failing to overcome a door-side resistance between the first door-side pivot and the first link, thereby causing the first link to rotate about the the first pillar-side pivot while the first link remains rotationally stationary about the first door-side pivot; simultaneously with the foregoing step, transmitting the movement of the first link to the second link through the connecting member, thereby causing the second link to rotate about the the second pillar-side pivot while the second link remains rotationally stationary about the second door-side pivot; opening the door from the intermediate position to a fully-open position while overcoming the door-side resistance, thereby causing the first link to rotate about the the first door-side pivot; simultaneously with the foregoing step, transmitting the movement of the first link to the second link through the connecting member, thereby causing the second link to rotate about the the second door-side pivot while the second link remains rotationally stationary about the second pillar-side pivot.
