Abstract

A grommet is attached between a body panel and a trunk lid at a location spaced from a hinge structure that movably supports the trunk lid. The grommet forms a wiring passageway between an opening in the body panel and an opening in the trunk lid. The grommet includes a body mounting end, a closure panel mounting end, a first flexible section, a second flexible section and a middle flexible section. The first flexible section extends from the body mounting end and the second flexible section extends from the closure panel mounting end. The middle flexible section extends between the first and second flexible sections in a free floating configuration with respect to the hinge structure, with the first and second flexible sections having a more bendable configuration than the middle flexible section.

the first flexible section has a first wall thickness, the second flexible section has a second wall thickness and the middle flexible section has a third wall thickness such that the third wall thickness is greater than either of the first and second wall thicknesses.

13. The vehicle grommet assembly according to claim 1 , wherein

the body mounting end, the closure panel mounting end, the first flexible section, the second flexible section and the middle flexible section are all made as a single unitary homogeneous member.

14. The vehicle grommet assembly according to claim 1 , wherein

the middle section pivots about one end of the first flexible section.

15. The vehicle grommet assembly according to claim 1 , wherein

the first flexible section and second flexible section are more flexible than the middle section.

16. The vehicle grommet assembly according to claim 15 , wherein

the first flexible section and second flexible section are configured and arranged to bend before the middle section when the closure panel is moved from the open position to the closed position.

17. The vehicle grommet assembly according to claim 15 , wherein

the middle section remains substantially straight as the closure panel is moved from the open position to the closed position.

18. The vehicle grommet assembly according to claim 1 , wherein

the first flexible section and the second flexible section are configured and arranged to bend as the closure panel moves between the open position and the closed position to prevent contact of the grommet member to the hinge structure.

19. A vehicle grommet assembly comprising:

a body panel having a first opening;

a closure panel having a second opening;

a hinge structure pivotally coupling the body panel to the closure panel for movement of the closure panel between a closed position and an open position; and

a wiring grommet member attached only to the body panel and closure panel free from connection to the hinge structure and forming a wiring passageway between the first and second openings, the grommet member including
