Abstract

A multi-joint hinge for a motor vehicle having a body and a panel, the hinge allowing the panel to be moved between an open position and a closed position relative to the vehicle body. The hinge includes at joint having at least one roller bearing, and is preferably a four bar joint having two bearings mounted on the body and two bearings mounted on the panel.

Claims

1. A multi-joint hinge for a motor vehicle having a body and a panel, the hinge allowing the panel to be moved between an open position and a closed position relative to the vehicle body, the hinge comprising at least one joint having a roller bearing.

2. The multi-joint hinge of claim 1 wherein the roller bearing comprises rolling elements, the rolling elements being at least one of balls, cylindrical rollers, needles, conical rollers, barrel rollers, convex rollers, rollers having ends with elevations, rollers having tapered ends, and rollers having ends with tips.

3. The multi-joint hinge of claim 2 wherein the roller bearing further comprises at least one of an inner bearing ring and an outer bearing ring for guiding the rolling elements.

4. The multi-joint hinge of claim 2 further comprising a bearing pin received through the roller bearing.

5. The multi-joint hinge of claim 4 further comprising a first lever and a second lever which are pivotable with respect to each other by means of the roller bearing.

6. The multi-joint hinge of claim 5 wherein the first lever has a first bore and the second lever has a second bore.

7. The multi-joint hinge of claim 6 wherein the bearing pin is received in the first bore in an interference fit.

8. The multi-joint hinge of claim 7 further comprising an outer bearing ring for guiding the rolling elements, the outer bearing ring being received in the second bore in an interference fit.

9. The multi-joint hinge of claim 8 further comprising an inner bearing ring for guiding the roller elements, the bearing pin being received in the inner bearing ring in an interference fit.

10. The multi-joint hinge of claim 4 wherein the bearing comprises an outer bearing ring, wherein the rolling elements are guided between the outer bearing ring and the bearing pin.

11. The multi-joint hinge of claim 6 wherein the rolling elements are guided between the first bore and the bearing pin.

12. The multi-joint hinge of claim 5 wherein the second lever is riveted to the bearing pin.

13. The multi-joint hinge of claim 1 wherein the hinge comprises a four-bar joint.

14. The multi-joint hinge of claim 13 wherein the four-bar joint comprises four roller bearings.

15. The multi-joint hinge of claim 14 wherein two of the bearings are mounted on the panel and two of the bearings are mounted on the vehicle.

16. The multi-joint hinge of claim 1 further comprising a source of energy to assist opening the panel.

17. The multi-joint hinge of claim 16 wherein the source of energy is a gas spring.

18. The multi-joint hinge of claim 16 wherein the source of energy is mounted to the vehicle body and the panel by pivot bearings.

19. A motor vehicle comprising:

a vehicle body;

a panel which can be pivoted between an open position and a closed position relative to the vehicle body; and

a multi-joint hinge fixed to panel and the vehicle body, the multi-joint hinge comprising at least one roller bearing.
