Vehicle body structure

1. A vehicle body structure comprising:

at least one vehicle body panel including a roof ditch that is defined by a recessed support surface, a first wall surface extending longitudinally along a first side of the recessed support surface and a second wall surface extending longitudinally along a second side of the recessed support surface, with the second wall surface being disposed outboard of the first wall surface;

a cover including a top portion that spans a width of the roof ditch between respective top edges of the first and second wall surfaces such that a first lateral side of the top portion extends along the first wall surface and a second lateral side of the top portion extends along the second wall surface, the cover further including a cover attachment section and a molding attachment section, the cover attachment section coupling the cover at a fixed position relative to the vehicle body panel; and

a molding member extending in a lengthwise direction along the roof ditch between the first and second wall surfaces of the roof ditch, the molding member including an attachment member and an attachment projection, the attachment member mating with the molding attachment section of the cover to form a lengthwise movement connection that retains the cover to the molding member such that the lengthwise movement connection allows the molding member and the cover to undergo a predetermined amount of movement relative to one another along the lengthwise direction of the roof ditch, the attachment projection extending under one of the first lateral side and the second lateral side of the cover with an upper surface of the top portion of the cover facing an underside of the molding member restricting movement of the molding member relative to the cover in a direction perpendicular to the lengthwise direction of the roof ditch.

2. The vehicle body structure according to claim 1 , wherein

the attachment projection is a snap fitting projection.

3. The vehicle body structure according to claim 1 , wherein

the attachment projection extends in a direction perpendicular to the lengthwise direction of the molding member.

4. The vehicle body structure according to claim 3 , wherein

the attachment projection extends in a direction perpendicular to the attachment member.

5. The vehicle body structure according to claim 1 , wherein

the attachment projection extends in a direction perpendicular to the attachment member.

6. The vehicle body structure according to claim 1 , wherein

the cover includes an insertion recess dimensioned such that with the molding member moving from an installation orientation to an installed orientation relative to the cover, the attachment projection is passed through the insertion recess.

7. The vehicle body structure according to claim 1 , wherein

the attachment projection is positioned to retain an upper surface of the top portion of the cover flush to an underside of the molding member.

8. The vehicle body structure according to claim 1 , wherein

the lengthwise movement connection includes a first slot that extends in the lengthwise direction of the roof ditch as a part of the molding attachment section of the cover, and the attachment member is movably disposed in the first slot in the lengthwise direction of the roof ditch.

9. The vehicle body structure according to claim 8 , wherein

the first slot is defined by the top portion of the cover.

10. The vehicle body structure according to claim 8 , wherein

the attachment member snap-fits into the first slot of the cover to secure the molding member to the cover.

11. The vehicle body structure according to claim 8 , wherein

the lengthwise movement connection further includes a second slot that extends in the lengthwise direction of the roof ditch as a part of the molding attachment section of the cover, and

the lengthwise movement connection further includes an additional attachment member that is disposed on the molding member and is movably disposed in the second slot.

12. The vehicle body structure according to claim 11 , wherein

the first and second slots are laterally offset from each other with respect to the lengthwise direction of the roof ditch.

13. The vehicle body structure according to claim 11 , wherein

the first and second slots are longitudinally offset from each other with respect to the lengthwise direction of the roof ditch.

14. The vehicle body structure according to claim 11 , wherein

the attachment members snap-fit into the first and second slots of the cover to secure the molding member to the cover.

15. The vehicle body structure according to claim 11 , wherein

the first and second slots are both laterally and longitudinally offset with respect to the lengthwise direction of the roof ditch.

16. The vehicle body structure according to claim 11 , wherein

the attachment projection is laterally aligned with one of the first and second slots and longitudinally offset with respect to the other of the first and second slots.

17. The vehicle body structure according to claim 11 , wherein

the attachment projection is a snap fitting projection.

18. The vehicle body structure according to claim 11 , wherein

the attachment projection extends in a direction perpendicular to the lengthwise direction of the molding member.

19. The vehicle body structure according to claim 18 , wherein

the attachment projection extends in a direction perpendicular to both of the attachment members.

20. The vehicle body structure according to claim 11 , wherein

the cover includes an insertion recess dimensioned such that with the molding member moving from an installation orientation to an installed orientation relative to the cover, the attachment projection is passed through the insertion recess.
