Abstract

An automotive hinge assembly adapted to facilitate motion of a closure panel relative to a fixed body structure comprises a door component constructed from two press formed angle brackets structurally connected via a pivot pin and adapted to be mounted to a vehicle closure panel, a body component constructed from two press formed angle brackets structurally connected via a simple formed feature and the pivot pin and adapted to be mounted to a vehicle body structure, such that the pivot pin structurally assembles the two hinge components, facilitates relative rotary motion between them and structurally connects the multiple press formed angle brackets so that the resulting assembly achieves a much higher material efficiency than the prior art with an associated significant cost reduction.

First claim

The invention claimed is:

1. A vehicular hinge assembly comprising:
a first component comprising first and second separate brackets, the first bracket being spaced apart from the second bracket;
a second component including a bushing aperture configured to accept a pivot bushing;
a pivot bushing;
a pivot pin that comprises a first end, a second end, and a pivot surface positioned between the first end and the second end, each of the first and second ends comprising an upset head following assembly of the hinge;
wherein the pivot surface of the pivot pin is disposed within the pivot bushing such that the second component is rotatable around the pivot surface, and the first and second ends of the pivot pin are structurally connected to the first and second brackets of the first component to hold the first and second brackets in a fixed relationship; and
wherein the upset heads of the pivot pin hold the first component and the second component together while permitting them to rotate relative to one another to form an assembly to be mounted as a whole to a vehicular closure panel and a vehicular body structure.

2. The vehicular hinge assembly of claim 1 , wherein each of the upset heads has a diameter greater than the diameter of each of the first end and the second end of the pivot pin.

3. The vehicular hinge assembly of claim 1 , wherein the upset heads are formed by material upset comprising at least one of riveting or staking.

4. The vehicular hinge assembly of claim 1 , wherein the first and second brackets of the first component have apertures for receiving the first and second ends of the pivot pin.

5. The vehicular hinge assembly of claim 1 , wherein the first and second ends of the pivot pin are knurled.

6. The vehicular hinge assembly of claim 1 , wherein the second component further comprises first and second separate brackets.

7. The vehicular hinge assembly of claim 6 , wherein the first bracket of the second component comprises a mating feature, and the second bracket of the second component comprises a matching alignment aperture, the mating feature being engaged within the matching alignment aperture using press fitting, welding, bonding, riveting or staking.

8. The vehicular hinge assembly of claim 1 , further comprising a hinge stop formation connected to, and projecting from, the second component to restrict the rotation of the first component within a predetermined angle.

9. The vehicular hinge assembly of claim 8 , wherein the second component further comprises a hinge stop aperture to allow the hinge stop formation to extend through the hinge stop aperture and to be mounted onto the second component.

10. A vehicular hinge assembly comprising:
a first component comprising first and second separate brackets, the first bracket being spaced apart from the second bracket;
a second component including an aperture;
a pivot pin that comprises a first end, a second end, and a pivot surface positioned between the first end and the second end, each of the first and second ends comprising an upset head following assembly of the hinge;
wherein the pivot surface of the pivot pin is disposed within the aperture of the second component such that the second component is rotatable around the pivot surface, and the first and second ends of the pivot pin are structurally connected to the first and second brackets of the first component to prevent relative rotation between the first and second brackets; and
wherein the upset heads of the pivot pin hold the first component and the second component together to form an assembly to be mounted as a whole to a vehicular closure panel and a vehicular body structure.

11. The vehicular hinge assembly of claim 10 , wherein each of the first and second brackets of the first component has an aperture, and the first and second ends of the pivot pin are secured within the apertures.

12. A vehicular hinge assembly comprising:
a first component comprising first and second separate brackets, the first bracket being spaced apart from the second bracket;
a second component including a bushing aperture configured to accept a pivot bushing;
a pivot bushing;
a pivot pin that comprises a first end, a second end and a pivot surface positioned between the first end and the second end, each of the first end and second end comprising means to structurally connect the pivot pin to the first and second separate brackets of the first component respectively;
wherein the pivot surface of the pivot pin is disposed within the pivot bushing such that the second component is rotatable around the pivot surface, and the first and second ends of the pivot pin are structurally connected to the first and second separate brackets of the first component so that the first and second brackets do not rotate in relation to each other;
wherein the first component and the second component are thus held together to form an assembly to be mounted as a whole to a vehicular closure panel and a vehicular body structure.

13. The vehicular hinge assembly of claim 12 , wherein the means to structurally connect the pivot pin to the first and second separate brackets includes a materially upset head on at least one of the first end and the second end of the pivot pin.

14. The vehicular hinge assembly of claim 13 , wherein the materially upset head on at least one of the first end and the second end of the pivot pin is formed by material upset comprising one of riveting and staking.

15. The vehicular hinge assembly of claim 12 , wherein the means to structurally connect the pivot pin to the first and second separate brackets includes materially upset heads on each of the first end and the second end of the pivot pin.

16. The vehicular hinge assembly of claim 15 , wherein the materially upset heads on each of the first end and the second end of the pivot pin are formed by material upset comprising one of riveting and staking.

17. The vehicular hinge assembly of claim 12 , wherein the first and second brackets of the first component have apertures for receiving the first and second ends of the pivot pin.

18. The vehicular hinge assembly of claim 12 , wherein the pivot pin is knurled adjacent each of the first and second ends.

19. The vehicular hinge assembly of claim 12 , wherein the second component further comprises first and second separate second component brackets.

20. The vehicle hinge assembly of claim 1 , wherein the second component comprises first and second body brackets.

21. The vehicle hinge assembly of claim 1 , wherein the second component comprises first and second door brackets.
