Modular deck lid hinge with coil springs
A vehicle body decklid hinge includes at least one hinge set carried by a bracket that retains a pivot pin and a retainer bar in a cantilevered manner. The pivot pin supports a lever, such as a gooseneck strap, that will be coupled to the hood, while the bracket includes a mount that will be carried by peripheral body structure around the decklid opening. The retainer bar carries a helically wound spring that secures one end of the spring for resistance to rotation about the axis of the bar. The other end of the spring engages an adjustor that variably urges the lever to pivot toward the open position. The method and apparatus reduce specificity of components and improve adaptably to various models and styles by reducing adjustments to tension variability in adjusting the biasing force applied to the decklid strap.
1. A decklid hinge for displaceably supporting a decklid to and between open and closed positions over an opening defined by peripheral vehicle body structure, comprising at least one hinge set, each hinge set comprising:
a support bracket with a mount for securing said bracket to the peripheral vehicle body structure;
a pivot pin carried cantilevered by said support bracket, at one end of said pivot pin;
a retainer bar carried cantilevered by and fixed against rotation to said support bracket at one end of said retainer bar;
a spring with a helically coiled strand portion, said coiled portion receiving said retainer bar within and said retainer bar retaining a first strand end; and
a linkage having a lever pivoted on said pivot pin, wherein said lever includes an adjuster engaging a second strand end for variably biasing said lever toward said open position.
2. The invention as described in claim 1 wherein said retainer bar is tubular.
3. The invention as described in claim 1 wherein said adjuster comprises a cam body with a plurality of engagement surfaces.
4. The invention as described in claim 3 wherein said cam body is rotatably mounted to said lever about an axis of rotation.
5. The invention as described in claim 4 wherein said cam engagement surfaces are radially spaced from said axis of rotation.
6. A method for modularizing a vehicle decklid hinge by installing a pair of hinge sets to a peripheral body structure defining an opening covered by the hood, the method comprising:
mounting a support bracket to said peripheral body structure;
carrying a pivot pin cantilevered on said support bracket;
carrying a retainer bar cantilevered on and fixed against rotation to said support bracket;
biasing a lever pivoted on said pivot pin with a spring including a helically coiled strand with an end that is held by the retainer bar, and adjusting the coupling of a second strand end to said lever for adjusting the biasing force.
7. The invention as described in claim 6 wherein said adjusting comprises rotating a cam mounted to said lever.
8. The invention as described in claim 7 wherein said cam includes a plurality of engagement surfaces, and said adjusting includes engaging said second strand end against selected engagement surfaces.
9. A decklid hinge for displaceably supporting a decklid to and between open and closed positions over an opening defined by peripheral vehicle body structure, comprising at least one hinge set, each hinge set comprising:
a support bracket with a mount for securing said bracket to the peripheral vehicle body structure;
a pivot pin carried cantilevered by said support bracket, at one end of said pivot pin;
a retainer bar carried cantilevered by and fixed against rotation to said support bracket at one end of said retainer bar;
a spring with a helically coiled strand portion, said coiled portion receiving said retainer bar within and said retainer bar retaining a first strand end;
a linkage having a lever pivoted on said pivot pin, wherein said lever includes an adjuster engaging a second strand end for variably biasing said lever toward said open position;
wherein said retainer bar is tubular; and
wherein said adjuster comprises a cam body with a plurality of engagement surfaces.
10. The invention as described in claim 9 wherein said cam body is rotatably mounted to said lever about an axis of rotation.
11. The invention as described in claim 10 wherein said cam engagement surfaces are radially spaced from said axis of rotation.
