Abstract
There is provided a roof structure of a vehicular body. The roof structure includes right and left side roof rails disposed on opposing sides of the vehicular body. The roof structure further includes a plurality of roof reinforcements installed in a spaced-apart relationship between the side roof rails and extending along a lateral direction across the vehicular body and a roof panel attached to the roof reinforcements, wherein at least one roof reinforcement of the plurality of roof reinforcements is a first roof reinforcement having a maximum width portion wider than a closest relative spacing between the first roof reinforcement and an adjacent roof reinforcement of the plurality of roof reinforcements on a first side of the first roof reinforcement.
Claims15
A roof structure of a vehicular body, comprising:
- right and left side roof rails disposed on opposing sides of the vehicular body;
- a plurality of roof reinforcements installed in a spaced-apart relationship between the side roof rails and extending along a lateral direction across the vehicular body, said spaced-apart relationship defining through apertures extending continuously from the right side roof rail to the left side roof rail between adjacent roof reinforcements;
- and
- a roof panel attached to the roof reinforcements, wherein at least one roof reinforcement of the plurality of roof reinforcements is a first roof reinforcement having a maximum width portion wider than the respective through apertures between the first roof reinforcement and two adjacent roof reinforcements of the plurality of roof reinforcements on opposing sides of the first roof reinforcement,
- wherein at least one of the respective though apertures between the first roof reinforcement and the two adjacent roof reinforcements has an hour-glass shape.
A roof structure of a vehicular body, comprising:
- right and left means for supporting a roof disposed along right and left sides of the vehicular body;
- a plurality of means for reinforcing the roof laterally installed in a spaced-apart relationship between the first and second support means, each extending along a lateral direction of the vehicular body, said spaced-apart relationship defining an open area extending continuously from the right supporting means to the left supporting means between adjacent lateral edges of adjacent roof reinforcement means;
- and
- a roof panel attached to the roof reinforcement means,
- wherein at least one roof reinforcement means of the plurality of roof reinforcement means is a first roof reinforcement means having a maximum width portion wider than respective open areas between the first roof reinforcement means and two adjacent roof reinforcements means of the plurality of roof reinforcements means on opposing sides of the first roof reinforcement means, and
- wherein at least one of the respective open areas between the first roof reinforcement means and the two adjacent roof reinforcements means has an hour-glass shape.
A method of forming a roof structure of a vehicular body having right and left side roof rails disposed on opposing sides of the vehicular body, the method comprising:
- disposing a plurality of roof reinforcements laterally across the vehicular body between the side roof rails and in a spaced apart relationship along a length of the vehicular body wherein the space apart relationship defines through apertures extending continuously from the right side roof rail to the left side roof rail between adjacent roof reinforcements;
- and
- attaching a roof panel to the roof reinforcements,
- wherein at least one roof reinforcement of the plurality of roof reinforcements is a first roof reinforcement having a maximum width portion wider than respective through apertures between the first roof reinforcement and two adjacent roof reinforcements of the plurality of roof reinforcements on opposing sides of the first roof reinforcement, and
- wherein at least one of the respective through apertures between the first roof reinforcement and the two adjacent roof reinforcements has an hour-glass shape.
A roof structure of a vehicular body comprising:
- a plurality of roof reinforcements disposed in a spaced-apart relationship between a pair of opposing side roof rails of the vehicular body, the spaced-apart relationship defining an hour-glass shaped through aperture extending continuously between the pair of opposing side roof rails, wherein the plurality of roof reinforcements have a greater relative width adjacent a front of the vehicular body than adjacent a rear of the vehicular body and a smaller relative spacing between the plurality of roof reinforcements adjacent the front of the vehicular body than the rear of the vehicular body.
